Although aspect has been found to be particularly troublesome for heritage language learners (Montrul, 2009; Silva-Corvalán, 1994), few studies have focused on teaching conceptual development of verbal aspect in the HL classroom. This paper contributes to filling this gap by proposing an innovative pedagogical design aimed at providing HL students with the opportunity to generate and transform a conceptual understanding of aspect through conscious interaction in significant, coherent, and systematic ways. Key words: CONCEPT-BASED INSTRUCTION, ASPECT, HERITAGE LANGUAGE LEARNERS, SPANISH, SOCIOCULTURAL THEORY ES Enmarcado dentro de la teoría sociocultural de la mente aplicada al desarrollo y aprendizaje de segundas lenguas (Lantolf y Poehner, 2014), este artículo expone una propuesta pedagógica dirigida a la implementación de la instrucción basada en conceptos (C-BI, por sus siglas en inglés) en el aula de español como lengua de herencia (español LH ), con el fin de promover el desarrollo e interiorización conceptual del aspecto gramatical. Aunque se ha comprobado que el aspecto entraña una especial dificultad en los aprendices de LH (Montrul 2009; Silva-Corvalán, 1994), no hay, por el momento, propuestas específicas sobre cómo enseñar a desarrollar conceptualmente el aspecto verbal en el aula de LH. El presente trabajo contribuye a llenar este vacío, proponiendo un diseño pedagógico innovador, enfocado en proporcionar a los aprendices de LH la oportunidad de desarrollar y transformar su comprensión del aspecto verbal a través de una interacción consciente y significativa con el concepto y una presentación del concepto coherente y sistemática. Palabras clave: INSTRUCCIÓN CONCEPTUAL, ASPECTO, APRENDICES DE LENGUA DE HERENCIA, ESPAÑOL, TEORÍA SOCIOCULTURAL IT Questo articolo si inquadra all’interno della teoria socioculturale della mente in relazione all’acquisizione della seconda lingua (Lantolf & Poehner, 2014). Il lavoro presenta una proposta pedagogica per l'impiego dell’Insegnamento basato su concetti (C- BI) nell'ambito della classe di spagnolo come lingua ereditaria (SLE), al fine di promuovere lo sviluppo ed internalizzazione del concetto grammaticale dell’aspetto verbale. Sebbene si è visto che l'aspetto verbale è particolarmente difficile per studenti di SLE (Montrul, 2009; Silva-Corvalán, 1994), scarseggiano studi che si concentrino sull'insegnamento dello sviluppo concettuale dell'aspetto verbale nella classe di SLE. Questo testo contribuisce a colmare questa lacuna proponendo un innovativo disegno pedagogico volto a fornire agli studenti di SLE l'opportunità di generare e trasformare una comprensione concettuale dell'aspetto verbale attraverso la comunicazione consapevole in modi significativi, coerenti e sistematici. Parole chiave:   INSEGNAMENTO BASATO SU CONCETTI, ASPETTO VERBALE, STUDENTI DI LINGUE EREDITARIE, SPAGNOLO, TEORIA SOCIOCULTURALE GARCÍA     E-­‐JournALL  4(1)  (2017),  pp.  1–19     2   1.  Introduction   The  number  of  Spanish  speakers  in  the  United  States  has  grown  exponentially  in  the  past  20  years.   According   to   the   latest  American  Community   Survey,   13.1%  of   the   country’s   population   speaks   Spanish   at   home,  making   it   the  most  popular  non-­‐English   language  among  people  aged  5  or  older  (US  Census  Bureau,   2014).   In   the   face   of   this   reality,   American   higher   education   has   slowly   adopted   a   series   of   measures   to   promote  the  integration  of  heritage  bilinguals  in  college  classrooms  across  the  country  (for  a  comprehensive   overview,   see   Fairclough   &   Beaudrie,   2016).  What   started   as   the   implementation   of   remedial   courses   for   Spanish-­‐speaking  students  more  than  30  years  ago  (Valdés,  1997)  has  gradually  evolved  into  the  creation  of   programs  with   elaborated   curriculum   guidelines   and   learning   objectives   geared   toward   heritage   language   learners  (HLLs),  defined  as  “individuals  .  .  .  who  are  raised  in  homes  where  a  non-­‐English  language  is  spoken,   (or  who)  speak  or  merely  understand  the  HL,  and  are  to  some  degree  bilingual  in  English  and  the  HL”  (Valdés,   2001,  pp.  37-­‐38).   One   of   the   most   significant   changes   to   take   place   in   this   setting   was   the   understanding   that   the   psychological   and   linguistic   processes  behind  heritage   language   (HL)   acquisition  differ   in   some  ways   from   those   operating   in   second   language   (L2)   acquisition   (Montrul,   2002,   2009,   2011;   Valdés,   2005).   This   reconceptualization   of   heritage   language   learners   brought   about   the   transformation   of   one-­‐size-­‐fits-­‐all   models   to   meet   the   needs   of   this   highly   diverse   student   body   (Beaudrie,   2011).   If   we   consider   Valdés’s   definition   of  HLL,   given   at   the   end   of   the   previous   paragraph,   it   is   easy   to   see   that  HLLs   constitute   a   very   heterogeneous   community,   comprised   of   learners   with   varying   degrees   of   proficiency   and   literacy   in   the   heritage  language.  As  Carreira  (2012)  pointed  out,  the  interaction  of  students’  diverse  linguistic  profiles  with   socioaffective   factors   (i.e.   level   of   identification   with   the   Latino   community   or   confidence   regarding   their   linguistic  abilities)  calls  for  a  differentiated  approach  to  language  teaching.     In  this  paper,  I  present  a  pedagogical  sequence  for  implementing  concept-­‐based  instruction  (C-­‐BI)  in   the  heritage   language  classroom,  and   I  argue   that   the  adoption  of   this  model  provides   instructors  with   the   framework   needed   to   effectively   promote  HLL’s   cognitive   and   linguistic   development   through  meaningful,   transformative  activity.  Within  this  conceptual  approach,  the  implementation  of  different  instructional  tools   and   activities—such   as   written   and   oral   reflections   (verbalizations),   visual   models,   and   communicative   scenarios—creates  opportunities  for  heritage  learners  to  understand  complex  categories  of  meaning  through   conscious  and  contextualized  manipulation  of  concepts  (García,  in  press).     2.  Understanding  Spanish  heritage  language  learners   The   growing   number   of   heritage   speakers   (HS)  who   enroll   in   Spanish   classes   looking   to   improve   their   knowledge   of   the   heritage   language   raises   the   question   of   whether   their   grammars   and   linguistic   experience  are  comparable  to  those  of  L2  learners.  Montrul  (2012)  argues  that  beyond  differing  age  of  onset   of   bilingualism,   variations   in  HL   and  L2   learners’   settings   of   initial   acquisition   (naturalistic   vs.   instructed),   modes   of   input   (aural   vs.   aural   and   written),   and   frequency   of   input   (more   vs.   less   activation)   make   the   groups   fundamentally   different.   Additionally,   unlike   their   L2   counterparts,   HS   generally   undergo   a   certain   degree  of  attrition  and  reanalysis  in  their  home  language  due  to  a  wide  range  of  factors,  including  incomplete   acquisition  (Montrul,  2011),  low  levels  of  literacy  (Pascual  y  Cabo  &  Rothman,  2012),  and  lack  of  activation  of   the  heritage  language  (Putnam  &  Sánchez,  2013).  Prolonged  contact  with  the  majority  language  (English,   in   the  United  States)  from  an  early  age  is  also  likely  to  modulate  HS’  control  of  certain  grammatical  properties  in   the  home   language  (Montrul,  2011;  Pascual  y  Cabo  &  Rothman,  2012;  Putnam  &  Sánchez,  2013).  Aspectual   contrasts—the   focus  of   this  proposal—are  particularly  problematic   in   the  case  of  HL  grammar,  as   they  are   believed  to  be  mastered  around  the  ages  of  6;0-­‐7;0  in  monolingual  speakers  (Montrul,  2002),  the  time  when   HS  begin  schooling  in  English  and  often  undergo  a  shift  in  language  dominance  (i.e.  from  Spanish  to  English).   If   schooling   is   not   also   provided   in   the   HL,   reduced   input   and   decreased   use   of   Spanish   can   prompt   a   reanalysis   of   preterite/imperfect   contrasts,   following   English-­‐like   patterns   in  which   the   preterite   assumes   two  aspectual  values:  [±perfective]  (Montrul,  2002,  2009,  2011;  see  section  4.1  for  more  details).     2.1.  General  approaches  to  teaching  and  evaluating  HLLs  in  the  Spanish  classroom   Given  the  differences  between  HS  and  L2  learner  grammars,  the  teaching  of  HLLs  should  involve  the   adoption  of  specialized  techniques  that  take  into  consideration  the  affective  and  linguistic  needs  of  this  group   of  students.  The  field  of  Spanish  heritage  language  (SHL)  education  has  traditionally  focused  on  two  key  areas   of  the  HL  classroom:  the  implementation  of  fair  assessment  tools  capable  of  evaluating  such  a  heterogeneous   IMPLEMENTING  CONCEPT-­‐BASED  INSTRUCTION     E-­‐JournALL  4(1)  (2017),  pp.  1–19     3   student   population   and   the   development   of   effective   instructional   methods   dedicated   to   the   teaching   of   grammar   and   other   aspects   of   language.   Regarding   the   former,   Beaudrie   (2012,   2016)   and   Potowski   and   Carreira  (2004)  propose  that  placement  exams  and  classroom  assessments  should  be  as  individualized  and  as   flexible   as   possible.   As   Carreira   (2012)   showed,   this   can   be   achieved   by   setting   up   ongoing   formative   assessments  throughout  the  semester,  which  allow  for  close  monitoring  of  HLL’s  progress  and  the  adaptation   of   classroom   practices   to   better   suit   their   needs.   Regarding   instructional   methods,   the   pioneering   investigations  of  Montrul   and  Bowles   (2010)  and  Potowski,   Jegerski,   and  Morgan-­‐Short   (2009)   tackled   the   difficult   task  of   examining  whether   grammatical   instruction  would   foster  HLLs’   development   following   the   patterns  reported   in  L2  acquisition  (Norris  &  Ortega,  2000;  Russell  &  Spada,  2006).  Although  the  results   in   both   studies   indicated   that   HLLs   showed   significant   gains   in   comprehension   and   production   after   being   exposed  to  several  treatments,  it  was  not  clear  how  different  approaches  (processing  instruction,  traditional   techniques)  had  affected  their  performance.  Consequently,  Bowles  (2011)  and  Correa  (2011a)  proceeded  to   analyze  the  role  of  explicit  and  implicit  knowledge  in  HL  development,  evaluating   learners’  abilities  using  a   wide   range   of   experimental   tasks.   Data   from   these   investigations   showed   that,   when   compared   to   proficiency-­‐matched   L2   learners,  HLLs   exhibited   better   results   in  measures  where   explicit   knowledge  was   not  needed.       The  studies   summarized   thus   far   suggest   that   the  development  of   complex  grammatical  notions   in   HLLs  can  benefit   from  grammatical   instruction,  but   that  acquisition   is  highly  dependent  on  HLLs’  ability   to   build   upon   pre-­‐existing   knowledge.   Two   specific   approaches   that   attempt   to   capitalize,   therefore,   on   pre-­‐ existing  knowledge,  by  implementing  instructional  techniques  focused  on  the  links  between  mind,  language,   and  society,  are  Systemic  Functional  Linguistics  (SFL)  (Halliday,  1993,  1998,  2004)  and  Sociocultural  Theory   (SCT)   (Lantolf   &   Thorne,   2006).   Within   SFL,   the   work   of   Colombi   and   collaborators   has   explored   the   academic  and  linguistic  development  of  HLLs  (Achugar  &  Colombi,  2008;  Colombi,  2006,  2009;  Schleppegrell   &   Colombi,   2008).   From   a   systemic-­‐functional   perspective,   language   learning   is   understood   as   a   social   process   where   grammar   plays   a   central   role,   especially   in   more   advanced   uses   of   language   (Achugar   &   Colombi,  2008).  The  majority  of  these  studies  have  been  primarily  dedicated  to  the  teaching  and  development   of   two  areas   in  the  HL  classroom:  register  (academic/scientific  vs.   informal)  and  dialects  (standard  vs.  non-­‐ standard   varieties).  While   these   topics   provide  HLLs  with   the   opportunity   to   develop   the   skills   needed   to   achieve  advanced  biliteracy  (Colombi  &  Harrington,  2012),  they  do  not  address  specific  grammatical  notions   that   might   also   be   problematic   for   HLLs.   And   while   the   development   of   grammatical   concepts   has   been   examined   from   other   theoretical   perspectives,   in   this   paper,   I   propose   an   approach   to   HS   grammar   development   using   an   SCT   approach   to   language   learning   and   development.   The   next   section   reviews   the   main  tenets  of  the  SCT  approach,  as  well  as  the  most  relevant  investigations  dedicated  to  the  implementation   of  concept-­‐based  instruction  (C-­‐BI),  an  innovative  approach  focused  on  the  teaching  of  grammar  concepts  in   the  language  classroom.     3.  Concept-­‐based  instruction:  A  sociocultural  approach  to  aspectual  development  in   the  HL  classroom   Vygotsky’s   (1978)   cultural-­‐historical   theory  of   human   consciousness   is   the  basis   of   a   sociocultural   approach  (SCT)  to  the  study  of  second  and  heritage  language  development  (see  Lantolf  &  Poehner,  2014  for  a   general  overview).    One  of  Vygotsky’s  fundamental  claims  is  that  the  human  mind  is  mediated;  that  is,  human   beings   do   not   interact   directly   with   the   world,   but   through   physical   and   psychological   tools   (Lantolf   &   Thorne,  2006).  Mediation,   then,   indicates  that  conscious  human  activity   is  guided,  shaped,  and  transformed   by  material/physical  (i.e.  a  hammer,  a  phone,  a  pen)  and  psychological/symbolic  (i.e.  speech,   literacy,   logic,   geometry,   music,   etc.)   tools   and   artifacts.   In   his   theory   of   concept   formation,   Vygotsky   (1986)   makes   a   distinction   between   two   types   of   knowledge:   everyday   concepts   (learned   through   observation   and   characterized   by   being   highly   contextualized,   based   on   empirical   observation   and   subjective   to   concrete   practice)   and   scientific   concepts   (largely   abstract   and   systematic   in   nature,   and   generally   learned   in   educational   settings).   Everyday   concepts   typically   emerge   from   a   bottom-­‐up   reasoning   developed   from   empirical  observation  and  lack  the  malleability  to  be  transferred  to  other  contexts  (Vygotsky,  1986).  In  other   words,   learners   construct   these   notions   from   specific   experiences   and   internalize   them   through   abstract   thinking.   However,   while   spontaneous   concepts   facilitate   the   internalization   of   new   knowledge,   they   are   difficult  to  generalize  due  to  their  lack  of  systematicity  (Wertsch,  2007).  In  the  L2/HL  classroom  this  is  seen   in   learners’   and   teachers’   use  of   “rules   of   thumb”,  which  use  observations   and   situated   contexts   to   engage   GARCÍA     E-­‐JournALL  4(1)  (2017),  pp.  1–19     4   with  complex  grammatical  notions  (García,  2014;  Negueruela  &  Lantolf,  2006;  van  Compernolle,  2014).  This   type   of   simplified   rules   includes   recommendations   such   as   “always   use   the   imperfect   in   Spanish  when   an   action  is  repeated  in  the  past”,  or  “use  preterite  when  an  action  happens  only  once”  (see  Whitley,  2002  for  a   complete   review).   The   main   consequence   of   employing   this   type   of   everyday   knowledge   in   the   language   classroom   is   that   learners   often   fail   to   see   its   limited   functionality,   and   they   tend   to   apply   rules   indiscriminately   in  a  wide  variety  of   contexts   (García,  2012;  Negueruela  2003;  Negueruela  &  Lantolf  2006;   van  Compernolle  2014).   Vygotsky  (1986)  claimed  that  higher  forms  of  human  thinking  (e.g.  reasoning,  logical  deduction)  are   mediated   by   scientific   concepts,   due   to   their   high   levels   of   abstraction,   systematicity,   and   de-­‐ contextualization,  allowing  learners  to  consciously  manipulate,  transform,  and  apply  this  type  of  knowledge   to   multiple   contexts   (García,   in   press).   Hence,   pedagogical   approaches   within   this   framework   place   their   focus   in   teaching  scientific   (i.e.  abstract  and  systematic)   linguistic  concepts   to  mediate  heritage  and  second   language  learners’  internalization  of  complex  categories  of  meaning  such  as  mood,  voice,  tense,  or,  in  the  case   of  the  present  work,  aspect.  In  other  words,  an  SCT  pedagogical  approach  to  the  SHL  and  L2  classrooms  sees   learners   as   sense-­‐making   beings   and   focuses   on   putting   in  motion   a   coherent   and   systematic   approach   to   foster   learners’   ability   to   consciously   manipulate   scientific   concepts   as   tools   to   mediate   their   mental   and   communicative   activity   (Lantolf,   2011,   p.   24).   The   Vygotskyan   notion   of   using   scientific   concepts   as   mediational   tools   for   understanding   and   creating   meaning   in   the   teaching-­‐learning-­‐development   process,   developed   further   in   Davydov’s   (1999,   2004)   germ   cell   model   and   Gal’perin’s   (1989,   1992)   Systemic-­‐ Theoretical   Instruction   (see   Stetsenko   &   Arievitch,   2010   for   a   complete   analysis   of   both   methods),   is   considered  to  be  the  basis  of  C-­‐BI.     3.1.  Defining  concept-­‐based  instruction   As  it  name  indicates,  C-­‐BI  is  a  pedagogical  approach  where  learners  actively  interact  with  concepts  in   a   significant,   coherent,   and   systematic  manner   to   create   new  meanings   in   their   second/heritage   language.   While  the  materialization  and  transformation  of  conceptual  understandings  is  deemed  essential  to  promote   linguistic  development  (Negueruela  &  García,  2016),  communicative  activity  and  language  reflection  through   categories   of  meaning  play   a   fundamental   role   in   the   classroom.  As   a   result,   a   basic   C-­‐BI   sequence   always   intertwines  the  understanding  and  development  of  theoretical  concepts  through  didactic  models  with  the  use   of  verbalizations  (Negueruela,  2003,  p.  224).     Its   focus   on   development   as   a   conceptual   process   is   precisely   what   makes   C-­‐BI   different   from   mainstream  pedagogical   approaches.  While   traditional  models   of   L2   and  HL   instruction   expect   students   to   acquire   forms   first   and  meanings   second   (for   example,   learning   verbal  morphology   related   to   the   Spanish   preterite  and  imperfect  first,  and  then  their  respective  uses),  C-­‐BI  focuses  on  teaching  categories  of  meaning   and   explaining   how   they   are   connected   to   forms   in   context   (van   Compernolle,   2014).   In   summary,   a   C-­‐BI   approach   to   language   teaching  and  development   is  based  on   three  basic  principles.  First  and   foremost,   the   quality   of   the   explanation   given   to   the   students   matters;   thus   instructors   need   to   develop   pedagogically-­‐ adequate   accounts   of   the   phenomena   at   all   times.   Second,   conceptual   explanations   are   expected   to   be   presented,   using   concise   visual   representations   to   foster   learners’   assignment   of   functional   value   in   communicative  activity.  Lastly,  students  need  to  engage  in  social  interaction—with  the  self  or  with  others—to   convey   their   understanding   of   a   particular   grammatical   notion   through  written   and/or   oral   verbalizations   (Negueruela  &  García,  2016).       Although  research  suggests  that  C-­‐BI  is  a  feasible  tool  to  support  learners’  grammatical  development,   there   are   a   limited   number   of   publications   that   provide   specific   pedagogical   designs   detailing   how   this   approach   could   actually   be   implemented   in   the   HL   classroom   (Aguiló   &   Negueruela,   2015;   García,   2012;   Negueruela,  2003;  van  Compernolle,  2014;  Yáñez-­‐Prieto,  2008).  The  present  work  adds  to  the  literature  on  C-­‐ BI  by  proposing  a   complete  pedagogical   sequence   to  promote   the  conceptual  development  of  aspect   in   the   SHL  classroom.     3.2.  The  implementation  of  concept-­‐based  instruction  in  the  L2  classroom   In  the  years  since  Negueruela’s  (2003)  groundbreaking  study,  the  implementation  of  C-­‐BI  to  promote   the  development  of  categories  of  meaning  has  been  explored  in  a  wide  range  of  studies  across  languages.  For   example,   in  French,  there  have  been  investigations  in   literacy  (Buescher,  2015),  aspect  (Gánem-­‐Gutiérrez  &   Harum,   2011),   locative   prepositions   (Buescher  &   Strauss,   2015),   the   grammatical   concept   of   voice   (Swain,   Lapkin,  Knouzi,  Suzuki,  &  Brooks,  2009),  and  the  sociopragmatics  of  self-­‐representation,  social  distance,  and   IMPLEMENTING  CONCEPT-­‐BASED  INSTRUCTION     E-­‐JournALL  4(1)  (2017),  pp.  1–19     5   power  (van  Compernolle,  2014).  In  L2  English,  studies  have  examined  C-­‐BI  for  teaching  locative  prepositions   (White,  2012)  and  sarcasm  (Kim,  2013);   in  L2  Chinese,   tense   (Lai,  2012)  and   topicalization   (Zhang,  2014);   and   in  German,  declensions  (Walter  &  van  Compernolle,  2015).   In   the  Spanish  L2  classroom,  C-­‐BI  has  been   used   to  explore  aspect,   tense,   and  mood   (Negueruela,  2003,  2008);   locative  prepositions   (Serrano-­‐López  &   Poehner,   2008);   the   development   of   literary   metaphor   (Yáñez-­‐Prieto,   2008);   the   use   of   motion   events   as   mediational   tools   for   giving   directions   (Aguiló-­‐Mora   &   Negueruela,   2015);   the   sociopragmatics   of   self-­‐ representation,   social  distance,   and  power  applied   to   tú/usted   (van  Compernolle,  Webber,  &  Gomez-­‐Llaich,   2016);  and  the  concept  of  aspect  applied  to  the  relationship  between  Spanish  preterite  and  imperfect  tenses   (Gánem-­‐Gutiérrez  2016;  García,  2012,  2014;  Negueruela,  2003;  Polizzi,  2013).   Among   the   previous   studies,   Negueruela   (2003)   was   the   first   to   propose   a   well-­‐articulated   C-­‐BI   pedagogical  sequence.  In  that  investigation,  he  worked  with  12  intermediate  Spanish  L2  learners  to  improve   their  use  and  understanding  of  aspect.  After  being  exposed  to  a  didactic  design  similar  to  the  one  proposed  in   this   article   (see   Negueruela,   2003   and   2006   studies   for   more   details),   students   were   asked   to   engage   in   verbalization  activities  with  themselves  aimed  at  reflecting  on  and  promoting  their  aspectual  understanding.   Although   results   from  Negueruela’s   intervention   indicated   that   learners’  development  was  not  even  across   the  board,  there  appeared  to  be  a  connection  between  the  implementation  of  C-­‐BI  and  an  improvement  of  L2   learners’  control  of  aspect.       The   pedagogical   proposal   in   this   article—in   contrast   with   Negueruela   (2003)—is   geared   toward   HLLs  and   suggests  a  more  nuanced   teaching   sequence   that   includes  a  wide   range  of   activities   tapping   into   different  modalities  (oral  and  written)  and  involving  various  dynamics  (groups,  dyads,  and  individual  work),   aimed   at   enhancing   the   positive   effects   of   C-­‐BI   observed   in   previous   research   and   at   promoting   the   internalization  of  aspect  in  the  HL  classroom.     3.3.  The  implementation  of  concept-­‐based  instruction  in  the  HL  classroom   As  indicated  in  previous  sections,  HLLs’  exposure  to  the  home  language  occurs  largely  in  naturalistic   settings,   in  which  the  acquisition  of  grammatical  notions  such  as  aspect,  mood,  or  agreement  emerges  from   the  linguistic  input  received  (Montrul,  2009,  2011).  This  type  of  experience  with  the  heritage  language  stands   in  contrast  to  popular  L2  pedagogical  models,  which  typically  involve  the  explicit  instruction  of  morphology   and  prioritize  memorization  and  recognition,  often  creating  a  disconnect  between  meaning  and  form  (Correa,   2011b).  Unlike  those  models,  C-­‐BI  focuses  in  the  development  of  complex  grammatical  notions  by  exploring   the   semantic   and   pragmatic   value   of   the   underlying   concept   behind   them,   establishing   a   link   between   meaning  and  form  in  the  last  stages  of  the  instructional  sequence.  Given  HLLs’  informal  experience  with  the   heritage  language,  it  is  proposed  here  that  SCT  and  C-­‐BI’s  emphasis  on  meaning  and  contextualized  learning   activity  is  more  in  tune  with  this  population’s  needs  as  language  learners.   Despite   these   observations,   there   has   been   just   one   investigation   (García   Frazier,   2013)   that   has   attempted   to   adopt   C-­‐BI   for   the   SHL   classroom.   The   objective   of   García   Frazier’s   qualitative   study  was   to   improve   HLLs’   (N   =   6)   understanding   and   use   of   indicative   and   subjunctive   mood   by   exposing   the   HL   students   to   C-­‐BI   instruction.   García   Frazier   noted   that,   before   adopting   this   pedagogical   approach,   the   majority   of   the   students   exhibited   a   rather   simplified   perception   of   mood,   which   affected   their   oral   and   written   performance.   In   her   study,   she   proposed   the   use   of   systemic-­‐theoretical   instruction   (STI),   a   tool-­‐ mediated   teaching   and   learning   approach   created   by   Gal’perin   (1969,   1989,   1992),   based   on   Vygotskyan   principles.  As  noted  by  Negueruela  and  Lantolf   (2006),   “C-­‐BI   in   itself  does  not  constitute  a  pedagogy,  but  a   theoretical  claim  about   the  appropriate  object  of   instruction   in  any  educational  domain”  (p.  98).  As  such,   it   requires  the  implementation  of  concrete  didactic  models  (such  as  STI)  to  be  used  as  tools  for  cognitive  and   linguistic  development.  Given  the  difficulty  García  Frazier’s  students  showed  regarding  the  notion  of  mood  in   Spanish,  she  decided  to  use  Negueruela’s  (2003)  cheme  of  a  Complete  Orienting  Basis  of  an  Action  (SCOBA),   shown  in  Figure  1,  to  introduce  aspect  to  the  class.   GARCÍA     E-­‐JournALL  4(1)  (2017),  pp.  1–19     6   WHAT  IS  THE  INTENTION  OF  THE  SPEAKER?   Does  he/she  want  to  convey  a  specific  a;tude  towards  a   statement?  (influence,  evaluate,  or  comment)   YES   Use  SUBJUNCTIVE   NO   Does  he/she  want  to  convey  a  specific  knowledge?   (repor?ng  or  asser?ng)   YES   Use  INDICATIVE                                                       Figure 1. Adaptation of the SCOBA implemented by García Frazier (2013) in her C-BI study   García   Frazier’s   graphic   representation   was   designed   to   help   HLLs   visualize   the   semantic   and   pragmatic   parameters   that   trigger  mood   selection   in   Spanish.   The   SCOBA   illustrated   in   Figure   1   not   only   allowed  students  to  identify  the  meaning  behind  the  presence  of  indicative  or  subjunctive  in  the  subordinate   clause  of  given  sentence,  but  also   fostered  the  use  of   this  knowledge   in  new  communicative  contexts.  After   being  exposed  to  the  conceptual  unit  of  instruction  (mood)  by  means  of  the  SCOBA,  students  were  asked  to   complete   a   series   of   written   activities   (i.e.   making   recommendations,   asking   for   favors,   etc.)   and   verbally   reflect  on  their  modal  choices  based  on  the  provided  pedagogical  model  to  justify  their  choice  of  indicative  or   subjunctive.   These   oral   reflections   (i.e.   verbalizations),   aimed   at   fostering   L2   conceptual   development,   constitute  what  Gal’perin   (1969,   p.   260)   called  dialogic   thinking,   as   they   allow   learners   to  use   language   to   socially  interact  with  themselves  by  using  the  concepts  to  explain  their  linguistic  choices.  In  García  Frazier’s   study,   HLLs’   verbalizations  were   recorded   and   later   reviewed   by   the   instructor.   Once   these   activities   had   taken  place,  HLLs  were  prompted  to  construct  their  own  definition  of  mood  based  on  their  experience  with   the  concept.  The  analysis  of  students’  verbalizations  and  written  data  indicated  that  they  were  in  the  process   of  developing  a  much  more  nuanced  understanding  of  Spanish  mood.  This,  in  turn,  resulted  in  higher  levels  of   accuracy  in  their  use  of  indicative  and  subjunctive  in  a  wide  variety  of  contexts.  These  results  suggest  that,  on   the  whole,   the   implementation  of  a  concept-­‐based  approach  appeared   to  be  beneficial   for   the  development   and  maintenance  of  a  complex  grammatical  notion,  such  as  mood,  in  HLLs.     However,  from  an  SCT  perspective,  development  of  conceptual  categories  proceeds  socially,  through   both   intra-­‐personal   communication   (with   the   self)   and   inter-­‐personal   communication   (with   others)   (Negueruela,  García,  &  Buescher,  2015,  p.  23).  Therefore,  it  makes  sense  to  incorporate  activities  that  not  only   prompt  learners’  dialogic  thinking  with  the  self,  but  also  “communicated  thinking”  (Gal’perin,  1969,  p.  260),   wherein  learners  aim  at  making  their  reflections  comprehensible  to  others  and  receive  mediation  from  more   experienced  peers   to  maximize   their   learning  opportunities.   In   the   following   sections,   I   propose   a  detailed   pedagogical  sequence,  based  on  these  principles,   for   implementing  C-­‐BI   in   the  HL  classroom  to  present   the   concept  of  aspect.           IMPLEMENTING  CONCEPT-­‐BASED  INSTRUCTION     E-­‐JournALL  4(1)  (2017),  pp.  1–19     7   4.  The  pedagogical  proposal:  Teaching  aspect  through  C-­‐BI   4.1.  HLLs  and  the  acquisition  and  development  of  aspect  in  Spanish   The   instructional   sequence  presented   in   this   article   focuses   on   the   grammatical   concept   of   aspect,   more  specifically,  the  aspectual  contrasts  that  emerge  between  the  Spanish  preterite  and  imperfect  tenses.  As   reported  in  previous  sections,  there  have  been  several  studies  dedicated  to  the  teaching  and  learning  of  this   linguistic   notion  within   a   SCT   perspective   (Gánem-­‐Gutiérrez,   2016;   García,   2012,   2014,   2017;   Negueruela,   2003;  Negueruela  &  Lantolf,  2006;  Polizzi,  2013);  however,  this  is  the  first  proposal  that  presents  a  complete   pedagogical  sequence  focused  on  how  to  present  aspect  in  the  SHL  classroom.     HLLs  have  been  reported   to  exhibit  a  considerable  degree  of  attrition  when  dealing  with  aspectual   contrasts  even  at  high   levels  of  proficiency   (Borik,  2013;  Cuza  &  Miller,  2015;  Cuza,  Pérez-­‐Tattam,  Barajas,   Miller,  &  Sadowski,  2013;  Montrul,  2002,  2009,  2011;  Montrul  &  Bowles,  2010;  Montrul  &  Perpiñán,  2011;   Montrul  &   Slabakova,   2003).  Difficulties   in   this   area   stem   from   several   crosslinguistic   differences   between   Spanish   and   English   in   the   expression   of   aspect.   Spanish,   the   weaker   language   of   HLLs,   presents   a   very   complex  aspectual  system,  in  which  perfectivity  and  imperfectivity  in  the  past  are  conveyed  by  means  of  two   morphological  instantiations:  preterite  (1a)  and  imperfect  (1b).     1)   a.   Estela   comió   un  donut   de  chocolate       Estela   eat    [3psgPRET]   a  doughnut   of  chocolate       Estela  ate  a  chocolate  doughnut               b.   Estela   comía   un  donut   de  chocolate       Estela   eat    [3psgIMP]   a  doughnut   of  chocolate       Estela  ate  a  chocolate  doughnut     In   the   first  example  (1a)   the  preterite   form  comió   (“ate”)  marks  that   the  action  of  eating   is  seen  as   bounded  by  the  speaker;  its  duration  has  a  clear  beginning  and  end.  In  the  second  example  (2b)  the  imperfect   form  comía  (“ate”)  profiles  that  the  event  is  viewed  as  unbounded,  and  that  the  emphasis  of  the  action  lies  in   its   progressiveness   and/or   habituality.   The   problematic   issue   for   HLLs   is   that,   while   English   and   Spanish   overlap  in  their  expression  of  perfectivity,  they  differ  in  the  way  they  convey  imperfectivity.  As  shown  in  the   second  example   (1b),  Spanish  generally  expresses  unbounded  events  with   imperfect   forms.  English,  on   the   other  hand,  resorts  to  a  wide  variety  of  alternatives  to  convey  the  same  notion1.   The   contrast   between   these   two   languages   causes   English-­‐dominant   HLLs   to   have   difficulties   remapping   [±perfective]   aspectual   features   to   the   corresponding   tense/aspect   morphemes   in   their   home   language  (Spanish).  In  particular,  many  studies  have  reported  that  HLLs  lose  the  preterite/imperfect  contrast   in  favor  of  the  adoption  of  a  single  tense  (preterite)  to  convey  perfectivity  and  imperfectivity  (Montrul,  2002,   2009,   2011;   Silva-­‐Corvalán,   1994).   In   addition   to   the   challenges   that   emerge   from   the  mere   fact   of   being   bilingual,   mastery   of   this   linguistic   property   is   also   affected   by   the   interaction   of   the   inherent   lexical   properties  of  a  specific  verb  (i.e.  lexical  aspect)  and  other  linguistic  components  that  extend  beyond  the  verb   phrase,   such   as   temporal   markers   and   nominal   arguments   (Verkuyl,   1972).   If   we   focus   on   the   former,   a   considerable  number  of   investigations   in   the   fields   of   first   and   second   language   acquisition  have  observed   that  speakers  (monolingual  and  bilingual)  tend  to  express  congruent  combinations  of  lexical  and  grammatical   aspect   (that   is,   telic   predicates   with   the   preterite,   and   atelic   ones   with   the   imperfect)   more   so   than   non-­‐ congruent   ones   (Andersen   &   Shirai,   1994;   Bardovi-­‐Harlig,   2000).   This   preference,   known   as   Primacy   of   Aspect  Hypothesis  (PAH),  is  also  predicted  to  affect  HLLs,  especially  given  the  reinforcement  of  this  tendency   by  means   of   rules   of   thumb   (ROTs)  when  HLLs   are   enrolled   in   a   language   class   (see   section   3.1   for  more   information).   The  widespread  presence  of   these   issues   in  heritage  Spanish  populations  underscores   the  need   for   effective   pedagogical   interventions.   The   following   section   outlines   a   suggested   timeline   for   the   1  Some  of  these  alternatives  include  the  use  of  the  simple  past  –i.e.  preterite  forms-­‐  (Estela  ate  a  chocolate  doughnut)  or   different   types  of  periphrases   that   emphasize   either   the  habituality  of   the  action   (Estela  used   to/would   eat  a   chocolate   doughnut)  or  its  progressive  nature  (Estela  was  eating  a  chocolate  doughnut).  Note  that  the  last  periphrastic  option  is  also   available  in  Spanish  (Estela  estaba  comiendo  un  donut  de  chocolate),  but  the  auxiliary  verb  (estaba;  “was”)  appears  in  the   imperfect.   GARCÍA     E-­‐JournALL  4(1)  (2017),  pp.  1–19     8   implementation  of  a  C-­‐BI  sequence  and  provides  thorough  descriptions  and  samples  of  the  types  of  activities   and  instruments  included.     4.2.  Components  and  implementation  of  the  instructional  sequence   It   is   important   to   note   that,   from   an   SCT   perspective,   research   and   teaching   are   not   seen   as   two   separate  practices,  but  rather  as  a  unified  activity  (Lantolf  &  Poehner,  2014).  Consequently,  the  effectiveness   of  any  type  of  pedagogical  decisions  made  in  the  classroom  should  be  examined  by  the  instructor  from  two   different   perspectives:   that   of   a   practitioner   and   of   a   researcher   (García,   2012,   p.   8).   This   dialectical   relationship  allows  language  teachers  to  put  into  practice  new  ideas  and  modify  previous  ones  based  on  the   observation  and  careful  study  of  students’  learning  processes.  Thus,  although  the  implementation  described   below  was  originally  designed  to  take  place  during  four  sessions  of  70  minutes  each,   it  could  be  adapted  to   different  settings  in  order  to  work  around  specific  constraints  (total  length  of  the  session,  number  of  weekly   meetings,  specific  needs  of  the  students,  etc.).       Table 1 Timeline of the pedagogical implementation Session Objectives and Description Day 1: Pedagogical intervention: CB-I and aspect • The students and the instructor explore their previous knowledge on aspect and preterite and imperfect • Implementation of CB-I Days 2 and 3: Practicing the use of preterite and imperfect • Completion of controlled activities on the use of preterite and imperfect (contextualized multiple choices, elicited narratives) • Communicative scenarios (Di Pietro, 1987) Day 4: Reflecting on the concept of aspect • Individual reflections and completion of activities • Mediated interview (student-instructor)       The  pedagogical  sequence  outlined  in  Table  1  draws  from  the  models  presented  in  García  (2012)  and   García  and  Perez-­‐Cortes  (2017),  two  studies  focused  on  fostering  the  development  of  grammatical  categories   in   L2   learners   and   HLLs   respectively.   Although   these   investigations   implemented   C-­‐BI   in   the   language   classroom,  they  were  both  empirical  studies  that  focused  on  verbalization  data  obtained  after  the  completion   of   several   experimental   tasks   and   they   both   sought   to   determine   the   effectiveness   of   C-­‐BI   and   dynamic   assessment  to  promote  these  populations’  aspectual  development.  This  article  builds  on  those,  by  proposing   and   describing   a   pedagogical   sequence   to   implement   C-­‐BI   in   the   heritage   language   classroom,   providing   a   model  for  practitioners  to  use  directly  in  their  own  classrooms  or  a  template  to  be  adapted  according  to  their   own  pedagogical  needs.     It   is   highly   recommended   that   the   instructor   begin   by   gathering   extensive   information   about   the   HLLs’   previous   knowledge   of   preterite   and   imperfect   aspectual   contrasts   and   uses   before   the   start   of   the   session.  Given  the  documented  production/comprehension  asymmetries   in  HLLs  (Hendriks  &  Koster,  2010;   Sherkina-­‐Lieber,   2011)   and   their   sometimes-­‐limited  metalinguistic   knowledge,   this   proposal   advocates   for   the   use   of   tasks   tapping   into   different   skills   (comprehension,   production,   and   acceptability   judgments)   to   gauge  students’  underlying  linguistic  abilities.  During  this  evaluative  stage—prior  to  the  implementation  of  C-­‐ BI—HLLs  would  be   asked   to   complete   a  written   task  based  on   their   perceptions   and  previous   knowledge.   They   would   be   prompted   to   listen   to   two   pairs   of   sentences   (also   be   presented   in   written   form   on   the   blackboard),  and  asked  to  determine  whether  they  detect  any  semantic  difference  between  them.  In  order  to   expedite  the  process,  answers  should  be  done  in  writing  and  handed  to  the  instructor.  For  example:             IMPLEMENTING  CONCEPT-­‐BASED  INSTRUCTION     E-­‐JournALL  4(1)  (2017),  pp.  1–19     9   2)   a.   El   barco   llegó

  two-­‐fold.  On   the   one  hand,   it   reveals  whether   students   are   sensitive   to   aspectual  contrasts  triggered  by  the  use  of  preterite  and  imperfect  before  they  are  exposed  to  C-­‐BI.  Given  the   diverse   nature   of   the   verbs   used   (telic   and   atelic),   their   responses   are   also   able   to   identify   any   potential   lexical  constraints  that  may  limit  students’  aspectual  control.  On  the  other  hand,  this  activity  promotes  HLLs’   awareness   of   perfective/imperfective   distinctions   in   Spanish,   a   first   step   towards   concept   formation   and   conceptual  development  of  the  notion  of  aspect.   In  addition  to  this  short  reflection,  the  instructor  would  also  ask  HLLs  to  write  a  couple  of  sentences   explaining  when  they  use  the  preterite  as  in  (2a)  and  (3a)  or  the  imperfect  as  in  (2b)  and  (3b).  The  evaluation   of  the  results  can  be  used  as  an  initial  assessment  of  the  students’  previous  knowledge,  as  well  as  a  potential   source   for   future   interventions,   as   it   provides   details   about   the   learners’   potential   development   that   will   inform  about   the   type  of  mediation  required   to   foster  conceptual  development  across   the  board,   inevitably   improving   the   quality   of   the   teaching-­‐learning   process.   One   way   of   dealing   with   differences   in   learners’   previous  knowledge  of  aspect  that  may  arise  in  this  task  would  be  to  group  students’  according  to  their  Zones   of   Proximal   Development   (ZPDs)2,   following   Lipkina   (1994)   and   Petrovsky   (1985).   The   aim   would   be   to   create  heterogeneous  groups  of  learners  with  differing  levels  of  control,  who  would  promote  different  kinds   of  mediation  (inter-­‐  and  intra-­‐group  mediation,  self-­‐mediation  and  instructor-­‐group  mediation).       4.2.1.  Implementing  C-­‐BI  to  the  teaching  of  aspect   After  the  initial  assessment,  C-­‐BI  is  then  implemented.  The  approach  to  C-­‐BI  is  based  on  Negueruela   (2003)   and   García’s   (2012)   proposals   for   the   development   of   concepts   as   categories   of  meaning.   In   these   studies,  exposure  to  coherent  and  systematic  didactic  models,  as  well  as  to  the  conscious  manipulation  of  the   concept  through  significant  communicative  activity  and  language  reflection,  played  a  fundamental  role  in  the   development  of  aspect.  These  principles  come  into  play  here  when  students  are  asked  to  form  small  groups  of   3  or  4  and  to  share  the  working  definitions  of  aspect  they  had  created  during  the  previous  activity.  Although   at   this   point   it   is   expected   that  most   of   the   definitions  would   rely   on   previously   acquired   rules   of   thumb   and/or  observations,   it   is  beneficial   to  establish  a  dialogue  so  that  students  can  become  more  familiar  with   the  conceptual  category  at  hand.     After   this   step,   HLLs   would   be   presented   with   a   SCOBA,   designed   as   a   mediational   tool   for   internalizing   the   grammatical   concept   of   aspect   in   Spanish.  Based   on  Bolinger’s   (1991)   formal   accounts   of   aspect,   and  Bull’s   (1984)   and  Whitley’s   (2002)   supporting   visual   representations,   the  model   suggested   for   this  proposal—shown  in  Figure  2  below—consists  of  two  parts:  1)  a  short,  written  explanation  tackling  the   notions  of   lexical   and  grammatical   aspect,   as  well   as   the   importance  of   the   speaker’s  perspective;   and  2)  a   chart  contrasting  the  preterite  and  imperfect  tenses  using  visual  cues.   2  If  we  follow  Vygotsky’s  (1986)  original  definition  of  ZPD  created  in  the  context  of  child  psychology,  this  notion  is  used  to   determine  the  child’s  potential  cognitive  development,  as  indicated  by  the  distance  between  what  the  child  can  do  on  his   own  and  what  can  do  with  the  assistance  of  an  adult  or  a  more  developed  individual.   GARCÍA     E-­‐JournALL  4(1)  (2017),  pp.  1–19     10   Understanding ASPECT The concept of aspect indicates the speaker’s perspective on an action. That is, what is the part/action that you as the speaker/writer want to emphasize. Aspect is determined by two factors: a) Lexical aspect: based on the meaning of the verb (bounded or unbounded). b) Grammatical aspect: based on the context of an action (perfective or imperfective) When these two elements are combined, they can emphasize the beginning, middle, end, or completion of an action. The speaker’s perspective over the past action to choose between preterite and imperfect is determined by the following questions: • What part of the action is the speaker emphasizing? • Does the verb have bounded meaning (e.g. to fall)? • Where in the past is the action from our present perspective? PRETERIT IMPERFECT Indicates the beginning or end of an action or that an action is completed from the present perspective (our perception from the present). Profiles an action that has no boundaries (limits) in the past. Salí de casa a las 6:00 (bounded event, points to the beginning of the action) El banco cerró a las 3:00 (bounded event, points to the end of the action) Viví en Londres durante un año (Completed action from a present perspective) Juan vivía en Perú (unbounded event, we don’t know its beginning, end, or duration in the past) Figure 2. SCOBA used during the implementation of C-BI   present ending present beginning IMPLEMENTING  CONCEPT-­‐BASED  INSTRUCTION     E-­‐JournALL  4(1)  (2017),  pp.  1–19     11   Following  the  presentation  of  the  SCOBA,  learners  should  be  given  some  time  to  explore  and  discuss   the  materials,   ideally   in  heterogeneous   groups  previously   formed  according   to   their   ZPD   in   relation   to   the   concept  of  aspect.  In  groups,  students  would  compare  their  initial  definitions  of  aspect  with  the  information   given   in   the   visual   representation.   Next,   since   the  main   objective   of   the   didactic  model   is   to   orient   HLLs’   performance,  it   is  recommended  to  have  a  phase  of  explicit   instruction  where  the  teacher  presents  the  new   grammatical   notions,   using   the   provided   SCOBA.   Then,   to   ensure   that   the   learners   understand   this   pedagogical  representation,  the  final  step  of  this  class  session  would  incorporate  a  practical  application  of  the   model  to  solve  an  activity.  Once  again,  students  would  return  to  their  groups  and  would  be  asked  to  analyze  a   narrative   in   the  past   in   their  dominant   language.   For   example,   in   a   class  of   Spanish  HLLs  whose  dominant   language  is  English,  students  could  be  exposed  in  English  to  the  theme  song  of  “The  Fresh  Prince  of  Bell-­‐Air”3.       Figure 3. Fragment of “The Fresh Prince of Bel-Air” lyrics used in an activity during the first session. The  lyrics,  a  short  narrative  from  the  show,  “The  Fresh  Prince  of  Bel-­‐Air,”  would  be  analyzed  by  all   the  members   of   the   group.   Students  would   be   instructed   to   underline   all   the   verbs   in   the   past   tense   that   appear   in   the   song.   They   would   then   discuss   whether   they   describe   perfective   or   imperfective   actions,   connecting   it   to   the   concept   presented   in   the   SCOBA   in   order   to   decide   whether   that   action   would   be   expressed  in  the  preterite  or  the  imperfect  in  Spanish.  As  mentioned  earlier,  unlike  Spanish,  English  does  not   mark   aspectual   distinctions   in   the  past  morphologically;   however,   both   languages   can   express   actions   that   profile  perfective  or   imperfective  events   in   the  past.  This   type  of   comparative  activity   is  designed   to   foster   HLLs’   awareness   towards   aspectual   distinctions   in   their   dominant   language   (i.e.   English),   which   can   be   bridged   to   their   heritage   language   with   the   mediation   of   the   proposed   pedagogical   model.   Ideally,   the   correction  of  this  task  would  take  place  at  the  end  of  the  session  so  that  the  different  groups  would  have  to   justify   their   choices,   using   the   SCOBA,   in   front   of   their   peers   and   so   that   they   would   receive   immediate   feedback  and  mediation  from  the  rest  of  the  class  (instructor  included).  However,  it  is  also  possible  to  resume   the  activity  at  the  beginning  of  the  next  session  to  confirm  that  students  had  understood  the  material  or  have   them  complete   the  activity  as  homework,  using   the  opportunity   to  have   learners  reflect  upon   their  choices   and   voice-­‐record   their   rationale   for   each   of   their   decisions   with   the   support   of   the   previously   presented   SCOBA.  This  verbalization  technique,  used  by  Negueruela  (2003)  to  foster  L2  conceptual  development,  draws   from  what  Gal’perin  (1969,  p.  260)  called  dialogic   thinking,  as   it  allows   learners  to  use   language  to  socially   interact  with  themselves  by  using  the  concepts  to  explain  their  linguistic  choices.     Lantolf  and  Poehner  (2014)  indicate  that  “concepts  are  relevant  for  the  formation  of  consciousness   because   they   shape  how  we  perceive,  understand,   and  act   in  and  on   the  world”   (p.  61).  This  activity  helps   HLLs  to  do  precisely  that.  While  the  use  of  HLLs’  dominant  language  (English)  is  generally  discouraged  in  the   communicative   language   classroom,   this   activity   allows   students   to   explore  new  concepts   in   a   comfortable   environment  and  create   interlinguistic  connections  among   languages  while  still  emphasizing  morphological   differences  in  expression.         3  This  song  can  be  substituted  by  another  song  or  text,  as  long  as  it  features  a  narrative  in  the  past.  As  mentioned  in  the   proposal,  the  goal  of  this  activity  is  for  students  to  determine  how  past  events  are  expressed  in  their  dominant  language   (English)  and  make  connections  with  their  weaker  one  (Spanish),  reflecting  upon  what  would  be  the  best  way  to  convey   the  same  aspectual  nuances.   In west Philadelphia born and raised   On the playground is where I spent most of my days

 communicative  activity   Presenting   HLLs   with   visual   tools   and   representations   (i.e.   SCOBAs)   is   not   enough   to   foster   true   conceptual  development  (Vygotsky,  1986,  p.  148).  In  order  to  bring  students  closer  to  that  goal,  they  need  to   be  able  to  manipulate  and  transform  concepts  through  meaningful  communication,  a  process  that  García  (in   press)  refers  to  as  conscious  conceptual  manipulation  (CCM).  At  this  stage,  it  is  essential  that  learners  engage   with   the   original   models   to   make   them   their   own   by   transforming,   internalizing,   and   externalizing   them   through  social  interaction  with  others  and  with  the  self  (Negueruela,  García,  &  Buescher,  2015).  In  the  second   session,   this  would  be   achieved  by   exposing  HLLs   to   a  wide   range  of   activities  where   they   can   apply   their   newly-­‐acquired  knowledge.     Ideally,  these  tasks  should  be  organized  from  more  to  less  structured  in  order  to  facilitate  students’   progress  toward  conceptual  development.  A  suitable  exercise  to  start  this  process  would  be  a  multiple-­‐choice   activity  with  8-­‐10  items,  wherein  students  would  have  to  choose  between  three  potential  answers  that  would   best  fit  the  blank  provided:     4)   Ella   __________  (ir)                       a  la  piscina   todas  las  semanas     She     ___________(goINF)   to  the  pool   all  the  weeks                 a)  iba     b)  fue   c)  ambas  son  posibles        went  [3psgIMP]   went[  3psgPRET]                  both  are  possible     5)   El  estudiante   __________  (comenzar)       a    trabajar   a    las    seis     The  student             ___________    (startINF)           to  work               to  the  six       a)  comenzó   b)  comenzaba   c)  ambas  son  posibles        started[3psgIMP]   started[3psgPRET]                  both  are  possible       As  illustrated  by  the  previous  examples,  the  target  sentences  feature  linguistic  characteristics  (such   as  certain  type  of  events,  adverbs,  and  other  details  of  time  and  duration)  usually  linked  to  the  use  of  either   preterite  or  imperfect  by  traditional  ROTs.  In  Question  4  this  was  achieved  by  the  presence  of  the  expression   todas   las  semanas   (“every  week”),  generally  associated  to  the   imperfect;  and  in  Question  5  by  a   las  seis   (“at   six”),   where   preterite   would   be   expected.   As   we   know,   however,   the   application   of   ROTs   simplifies   the   richness  and  flexibility  of  Spanish  aspect,  which  would  actually  allow  for  the  presence  of  both  tenses  in  each   of   the   examples.   The   objective   of   this   task   is   two-­‐fold.   On   the   one   hand,   it   informs   how  HLLs’  make   their   aspectual   choices   (i.e.   by   observation,   rules   of   thumb,   alluding   to   the   concept,   etc.),   and   on   the   other,   it   provides  learners  with  the  opportunity  to  manipulate  and  transform  the  conceptual  tools  provided  (SCOBA)   to  orient  their  responses  as  an  additional  step  towards  conceptual  development.   The   next   activity   is   designed   to   favor   the   communicative   strengths   present   in  HLLs   by   prompting   them  to  produce  a  written  narration  in  the  past,  conceived  to  trigger  the  use  of  preterite  and  imperfect  forms   in   context.   The   images   provided—based   on   a   short   comic   strip   from   the   Spanish   textbook   Dos   Mundos   (Terrell,  Andrade,  Egasse,  &  Munoz,  2002,  p.  422)—depict  a  sequence  of  events  where  Miguel,  a  young  bike-­‐ rider   is   accidentally   run  over  by  a   car,   then   taken   to   the  hospital  where  he   is   seen  by   the  doctors  until   he   recovers  from  his  injuries.     This  task,  which  would  be  revisited  during  the  last  session,  allows  learners  to  produce  preterite  and   imperfect   forms   in   a   contextually-­‐rich   environment;   however,   it   still   lacks   the   meaningfulness   and   communicative  value  needed  to  foster  internalization  (Gal’perin,  1969).  The  next  activity,  based  on  DiPietro’s   (1987)  scenarios,  provides  a  strategic   interaction  approach  to   language  pedagogy.  These  types  of  scenarios   are  comprised  of  three  interconnected  stages—preparation,  performance,  and  debriefing—and  allow  for  the   implementation  of  communicative  activity  and  language  reflection  in  the  classroom.  In  contrast  to  traditional   role-­‐playing,   DiPietro’s   proposal   includes   a   dramatic   element   where   students   have   different   agendas   and   where  none  of   the   learners  know  the  other’s   role   in   the  scenario.  These  characteristics  generate  situations   with   a   “communicative   meaning-­‐making   improvising   quality”   (Negueruela,   2003,   p.   226),   which   is   often   lacking  in  traditional  role-­‐playing  activities.  Figure  5  shows  this  activity.       IMPLEMENTING  CONCEPT-­‐BASED  INSTRUCTION     E-­‐JournALL  4(1)  (2017),  pp.  1–19     13   Original Activity Translation Situación – Dos amigos se encuentran para tomar un café. Uno de lleva saliendo con su novio/a más de un año . El gran problema es que están discutiendo todo el día y la semana pasada tuvieron una gran pelea. Situation: “Two best friends meet for coffee. One of them has been seeing his/her boyfriend/girlfriend for more than a year. The big problem is that they’re always arguing, and last week they had a big fight. Estudiante A: Estás muy enfadado/a con tu novio/a y le cuentas a tu mejor amigo/a tu versión de la discusión y le explicas porque está discusión fue diferente de las anteriores. Le pides a tu mejor amigo/a que te aconseje lo que deberías hacer. Student A: “You are very angry with your boyfriend and tell your best friend your version of the discussion, explaining why it was different from the previous ones. You ask your best friend to advise you on what to do next. Estudiante B: Tu mejor amigo/a te cuenta la discusión que tuvo con su novio/a la semana pasada. Tú estás cansado/a de escucharle hablar siempre de sus problemas de pareja y le recomiendas que rompa con su novio/a basándote en tus experiencias de pareja anteriores. Student B: Your best friend tells you about the discussion he/she had with her/his boyfriend/girlfriend last week. You are tired of listening to him/her talk about their relationship problems and recommend that they break up based on your previous experiences. Figure 5. Sample of García’s (2012) design of a scenario (DiPietro, 1987) for strategic interaction     The   implementation   of   this   task   would   be   staged   as   follows:   First,   HLLs   go   through   a   short   “preparation”  process  in  small  groups,  where  they  receive  instructions  about  their  role  and  the  context  they   will  be  working  on.  Once  this  phase  is  completed,  each  group  performs  their  scenario  in  front  of  their  peers,   who   in   turn,   take   notes   regarding   the   use   of   preterite   and   imperfect.   During   the   last   stage,   known   as   “debriefing”,  the  whole  class  provides  feedback  using  conceptual  explanations  with  the  help  of  their  SCOBAs.   If   students   are   not   able   to   justify   their   aspectual   choices   adequately,   the   instructor   would   provide   the   appropriate  mediation  to  ensure  the  conceptual  explanations  were  understood.     As   argued   throughout   this   article,   one   of   the   keys   to   internalization   lies   in   fostering   learners’   conscious  conceptual  manipulation  (CCM)  in  the  classroom,  allowing  them  to  reflect  upon  their  performance   by  creating  new  abstract  models  to  orient  their  actions  (in  this  case,  their  aspectual  choices).  Although  the  2-­‐3   sessions  described  so  far  provide  opportunities  for  HLLs  to  familiarize  themselves  with  the  concept  of  aspect   with  the  help  of  the  SCOBA,  they  have  not  been  involved  in  the  modification  of  this  diagram  based  on  their   own  emerging  understanding  of  this  notion.  This  appropriation  and  transformation  from  the  original  model  is   reported  to  increase  learners’  agency  “to  the  extent  that  it  allows  them  to  participate  in  the  co-­‐construction  of   new  knowledge”  (Stanfield,  2014,  p.  175).  Therefore,  the  last  session  would  be  dedicated  to  the  deployment   of  tasks  that  emphasize  introspection  and  CCM,  while  still  exposing  students  to  limited  dialogic  interactions.      4.2.3.  Reflecting  on  the  concept  of  aspect   In  this  fourth  and  final  session,  given  that  the  goal  is  reflection  on  the  part  of  the  learner,  the  majority   of   the   activities   proposed   have   either   a   dyadic   component   led   by   the   practitioner   or   an   individual   focus.   Following   the   suggestions   by   Negueruela-­‐Azarola   (2013)   and   García   (2017),   during   the   first   part   of   the   session,   learners  would  engage  with   the  original  models   and   transform   them   to  appropriate   them   through   conscious   conceptual   manipulation   in   social   interaction   with   others   and   with   the   self.   These   pedagogical   models   then   not   only   become   a   useful   tool   for   the   instructor,  who   is   able   to   observe   learners’   conceptual   development   in   the  making,  but  also   for   learners,  who  are   stimulated   to  use   scientific   concepts   to  mediate   their  thinking.     Once  students  have  created  their  models,  they  would  be  asked  to  revisit  two  of  the  five  activities  they   had   previously   completed   (the   multiple-­‐choice   test   and   the   written   elicited   narration)   during   a   short,   mediated  interview  conducted  by  the  teacher.  The  main  objective  of  these  dyadic  interactions  is  to  reveal— and   prompt—instances   of   conceptual   development   in   the   making   and   thus   to   provide   more   accurate   information  about  HLLs’  progress  than  could  be  learned  from  their  performance  in  static  activities.  As  noted   by  García  (2012),  when  engaged   in  verbalization  activities,   learners  do  not   limit   themselves   to   talk  about  a   grammatical   concept;   instead,   they   talk   through   the   concept   to   solve   a   particular   task.   As   a   result,   these   dialogic   interactions   are   expected   to   prompt   complex   justifications   for   students’   choice   of   preterite   and   imperfect   in   specific   situations   (with  or  without   the  help  of   the   SCOBA),   inevitably   exposing   students’   real   understanding  of  the  concept  of  aspect.   GARCÍA     E-­‐JournALL  4(1)  (2017),  pp.  1–19     14   In   contrast   with   previous   implementations   of   C-­‐BI,   the   present   proposal   incorporates   students’   reflections  (also  known  as  verbalizations)   in  a  wide  range  of  activities,   involving  the  participation  of  others   (groups   and   instructor-­‐student   dyads)   as   well   as   themselves.   This   variety   of   classroom   activities   is   particularly  beneficial  for  HLLs,  whose  levels  of  instructional  experience,  literacy,  and  proficiency  in  the  home   language  may  affect  how  they  perform  in  different  types  of  tasks  (Carreira,  2012).  Additionally,  the  possibility   of  receiving   immediate  mediation  by  the   instructor  and  by  peers  during  certain  classroom  activities   is  very   much  in   line  with  a  differentiated  approach  to   language  teaching,  essential   in  the  SHL  classroom  (Beaudrie,   2012,  2016;  Carreira,  2012).       5.  Conclusion   As   has   been   discussed   throughout   this   paper,   two  main   ideas   form   the   basis   of   C-­‐BI   for   the   SHL   classroom:  Vygotsky’s  (1986)  theory  of  concept  formation  and  Negueruela’s  (2003)  recommendations  for  the   design  and  implementation  of  pedagogical  models  focused  on  language  development  as  the  internalization  of   categories   of   meaning.   Grounded   in   those   sociocultural   principles,   this   paper   has   presented   a   didactic   sequence   aimed   at   the   development   of   the   grammatical   concept   of   aspect,   as   a   meditational   tool   for   understanding  and  gaining  control  over   the  heritage   language.  A  Vygotskian  approach  to   language   learning   and  development  proposes  that  properly  organized  learning  creates  and  promotes  conceptual  transformation   through  socially  mediated  and  significant,  goal-­‐oriented  activity  (Lantolf  &  Poehner,  2014).  This  is  precisely   what  has  been  proposed  in  the  present  article:  learners  consciously  engage  with  a  grammatical  concept  as  a   tool  for  thinking,  both  intrapersonally  or  interpersonally,  fostering  awareness  of  new  conceptual  categories  in   the  heritage  language.  This  process  of  engaging  with  concepts  and  actively  using  them  with  others  in  social   interaction   is   indeed   the   origin   of   conceptual   intra-­‐action,   leading   to   language   learning   and   development   (Negueruela-­‐Azarola,  García,  &  Buescher,  2015).  The  implementation  of  C-­‐BI  in  the  SHL  classroom  presented   in   this  paper   emphasizes   the   importance  of   all   these   sociocultural   elements,   including   the   crucial   role   of   a   properly-­‐organized  instruction  in  the  shaping,  development,  and  internalization  of  grammatical  notions.  This   paper  provides  practitioners  with  instructional  tools  to  foster  the  development  of  grammatical  categories  of   meaning   for   HLLs.   While   this   work   only   presents   a   proposal   for   putting   C-­‐BI   into   practice   in   the   HL   classroom,  a  detailed  discussion  of  empirical  data  related  to  the  implementation  of  this  pedagogical  sequence   can  be  found  in  García  &  Perez-­‐Cortes  (2017).     An  SCT  approach  to  HL  education  sees  HLLs  as  socio-­‐historical  beings  whose  agency  and  identity  are   mediated   by   their   experiences   and   social   interactions,   both   inside   and   outside   of   the   classroom   (García,   2014).  As  such,   it   seems   imperative   to  move  away   from  traditional  pedagogical  models  based  on  rules  and   repetition   and   to   embrace   those   that   empower   learners   and   foster   their   agency   as   they   co-­‐construct,   transform,   and   co-­‐own   their   learning   experiences.   Through   C-­‐BI,   teachers   also   become   mediators   who   provide   the   sense-­‐making   tools   and   significant   teaching-­‐learning   activity   that   allows   learners   to   be   active   participants  in  the  classroom.           References     Achugar,  Mariana,  &  Colombi,  Cecilia  (2008).  Systemic  functional  linguistic  approaches  to  longitudinal  studies   of   Spanish   heritage   learners.
