Abstract. As a result of the enactment of the National Education Act B.E. 2542 in Thai-
land, teachers have been encouraged to employ various methods for students’ 
learning assessment including student portfolio. Student portfolio is a collection of 
evidence that systematically reflects students’ learning processes and their learning 
outcomes in various aspects. The purposes of this study were to examine teach-
ers’ misconceptions in implementing student portfolio assessment, and to compare 
teachers’ current performance in implementing student portfolio assessment be-
tween teachers who had attended the training sessions concerning portfolio as-
sessment and those who had not. Four hundred and fifty-four elementary school 
teachers were randomly sampled to be participants in this study. Questionnaires 
were employed to collect data on teachers’ misconceptions about the principles of 
student portfolio assessment and the utilization of the results from student port-
folio assessment, as well as their current performance in implementing four main 
steps of student portfolio assessment [i.e., (a) planning for portfolio assessment, 
(b) collecting created products, (c) selecting products and reflecting on selected 
products, and (d) revising and evaluating products]. Results revealed that, overall, 
teachers had misconceptions in nine concepts. Six concepts were about the prin-
ciples of student portfolio assessment and three concepts were about the utiliza-
tion of the results from student portfolio assessment. Performance, which consisted

of implementing four main steps of student portfolio assessment, was higher for 
teachers who had attended the training sessions concerning student portfolio as-
sessment than for those teachers who had not attended the training sessions. The 
findings of this study could help related public sector personnel and teacher train-
ers from universities change teachers’ misconceptions more effectively.

Educational reform in Thailand which includes (a) curriculum re-
form, (b) teaching and learning reform, and (c) assessment reform, was 
enhanced after the enactment of the National Education Act of 1999. In 
the assessment reform, teachers have been encouraged to employ vari-
ous methods for students’ learning assessment as mentioned in the Sec-
tion 26 of the National Education Act. Authentic assessment, therefore, 
gained more interest from schoolteachers. Authentic assessment allows 
students to demonstrate the knowledge and skills learned from their 
lessons by creating a response or a task in real life situations (Cole, Ryan, 
Kick, & Mathies, 2000; Kinay, 2018; Mueller, 2005; Tangdhanakanond, 
Pitiyanuwat, & Archwamety, 2006a; Tangdhanakanond, 2016). Student 
portfolio is potentially an authentic assessment tool that teachers have 
been encouraged to use. 

Student portfolio is a collection of evidence that systematically 
reflects students’ learning processes and their learning outcomes in 
various aspects, such as achievement, skills, and characteristics (Chap-
puis, Stiggins, Chappuis, & Arter, 2012; Poowipadawat, 2001; Tangd-
hanakanond, 2016; Tangdhanakanond & Wongwanich, 2016; Tangd-
hanakanond & Wongwanich, 2012; Tangdhanakanond, et al., 2006a). 
In addition, portfolio could be used to monitor students’ learning de-
velopment continuously. Therefore, portfolio could be used for both 
formative and summative assessment purposes. Another advantage 
of portfolio is that its process could promote students’ achievement 
(Sootthipong, 2000; Chinnawong, 2000; Tangdhanakanond, Pitiyanu-
wat, & Archwamety, 2006b), achievement motivation (Chinnawong, 
2000), critical thinking (Koraneekid, 2007; Tyler & Dibble, 2019), ana-
lytic thinking (Tyler & Dibble, 2019), creative thinking (Sujarittanarugse, 
2005), meta-cognition (Gencel, 2016), self-directed learning (Elango, 
Jutti, & Lee, 2005; Tomkins & Quette-Frenette, 2010), and self-efficacy 
(Nicolaidou, 2012). Moreover, while students create their portfolios

(especially in the step of selecting products and reflecting on selected 
products, as well as the step of revising and evaluating products), they 
are encouraged by teachers to analyze their strengths and weaknesses 
in learning (Tangdhanakanond, 2005; Priest & Robert, 1998 as cited in 
McMullan, 2006). Portfolio is also used as a tool for communication be-
tween teachers and parents about students’ learning development and 
their characteristics (Kingkore, 1995; Benson & Barnett, 1999).

Literature proposes different steps in the portfolio process, depend-
ing on the learning activities, and portfolio purposes. Portfolio process 
is therefore flexible. However, the four common essential steps in the 
portfolio process are (a) planning for portfolio assessment, (b) collect-
ing created products, (c) selecting products and reflecting on selected 
products, and (d) revising and evaluating products (Burke, Forgerty, & 
Belgrad, 1994; Epstein, 2001; Educational Technique Department, 1996; 
Moonkum, 2000; Morin, 1995; Pearson Education Development Group, 
2001; Poowipadawat, 2001; Prawarnpruek, 1997; Punngam, 2000; Saer-
eerat, 1997; Siladech, 1997).

Kornketkamon (2001) found that Thai teachers had some difficul-
ties in the use of student portfolio assessment, especially in remind-
ing students to organize the products in their portfolios, reflecting on 
the created products, as well as revising and evaluating products in 
the portfolios. Moreover, Tangdhanakanond and Wongwanich (2015) 
found that Thai teachers lacked knowledge and deep understanding in 
implementing student portfolio assessment. They also recommended 
that an analysis of misconceptions of teachers in implementing student 
portfolio assessment should be conducted. Therefore, an examination 
of teachers’ misconceptions and current performance of teachers in 
implementing student portfolio assessment should be conducted. The 
purposes of this study were (a) to examine teachers’ misconceptions in 
implementing student portfolio assessment, and (b) to compare teach-
ers’ current performance in implementing student portfolio assessment 
between teachers who had attended the training sessions concerning 
portfolio assessment and those who had not. Findings on teachers’ mis-
conceptions and current performance of student portfolio assessment 
would produce valuable information for related sectors and personnel 
to conduct a conceptual change in teachers in the use of student port-
folio assessment in the future.

Participants

Participants were 454 elementary school teachers (134 male and 
320 female) from all regions (northern, middle, northeastern and south-
ern parts) of Thailand selected by multi-stage random sampling. Partici-
pants included 66 Thai language teachers, 69 mathematics teachers, 59 
sciences teachers, 58 career and technology teachers, 46 art teachers, 
54 social study teachers, 56 English language teachers, and 46 physical 
education teachers. Two hundred and thirteen participants taught in the 
lower elementary school levels (i.e., grades 1 to 3), whereas 241 partici-
pants taught in the upper elementary school levels (i.e., grades 4 to 6). 
In these numbers of participants, 229 teachers had 20 years of teaching 
experience or less, while 225 teachers had more than 20 years’ teach-
ing experience. Two hundred and nineteen participants had attended 
the training sessions related to student portfolio assessment, while the 
other 235 participants had not. 

Instrument

A survey questionnaire was employed in this research study. Before 
creating the questionnaire, related literature on portfolio process was 
studied (Burke et al., 1994; Educational Technique Department, 1996; Ep-
stein, 2001; Moonkum, 2000; Morin, 1995; Pearson Education Develop-
ment Group, 2001; Poowipadawat, 2001; Prawarnpruek, 1997; Punngam, 
2000; Saereerat, 1997; Siladech, 1997). Subsequently, five experts in the 
field of educational measurement and evaluation were selected to be 
interviewed about teachers’ possible common misconceptions in imple-
menting student portfolio assessment. The survey questionnaire was di-
vided into three parts. In part one, respondent gender, education level, 
teaching experience, as well as grades and subjects the respondents 
taught in schools were requested as the respondents’ demographic in-
formation. Respondents were also asked whether they had attended the 
training sessions related to student portfolio assessment in part one of 
the questionnaire. In part two, teachers’ misconceptions in implement-
ing student portfolio assessment were examined. Teachers were asked

43

to rate their understanding of various statements about the principles 
of student portfolio assessment and the utilization of the results from 
student portfolio assessment on a five-point rating scale (1=strongly 
disagree, 2=disagree, 3=undecided, 4=agree, 5=strongly agree). In part 
three, the respondents were asked to rate their current performance in 
implementing student portfolio assessment on a five-point rating scale 
(1=never, 2=rarely, 3=occasionally, 4= frequently, 5= very frequently). As 
mentioned earlier, student portfolio assessment was divided into 4 main 
steps, i.e., (a) planning for portfolio assessment, (b) collecting created 
products, (c) selecting products and reflecting on selected products, and 
(d) revising and evaluating products. The content validity of the ques-
tionnaire was examined by using the index of item-objective congruence 
(IOC). Five experts in the field of educational measurement and evalua-
tion were asked as content experts to independently rate the individual 
items on the degree to which they do or do not measure the specific 
objectives listed earlier by the researchers. More specifically, the content 
experts evaluated each item, for each objective, by giving the item the 
rating (1 = clearly measuring; 0 = degree to which it measures the objec-
tive is unclear; and -1 = clearly not measuring). Experts also were asked to 
suggest wording changes to improve the items. Then, the questionnaire 
was distributed to 30 elementary school teachers to check the reliability 
of the questionnaire. The reliability of the questionnaire was determined 
by Cronbach’s generalizability (G) coefficient in terms of internal con-
sistency of the items in each separate part of the questionnaire, as well 
as the total items in the questionnaire. It was found that the reliability 
of the various sets of items in regard to the teachers’ misconception in 
implementing student portfolio assessment (in the second part of the 
questionnaire) was 0.79, whereas the reliability of those in regard to the 
current performance in implementing student portfolio assessment (in 
the third part of the questionnaire) was 0.98. Overall, the reliability of this 
questionnaire (parts two and three combined) was 0.96.

Procedure

The questionnaires were randomly distributed to 640 elemen-
tary school teachers in all regions (northern, middle, northeastern and 
southern parts) of Thailand in a month. Four hundred and seventy-three

questionnaires were returned. Then, the 454 completed returned ques-
tionnaires were analyzed. Means and standard deviations were em-
ployed to analyze teachers’ misconceptions and their current perfor-
mance in the use of student portfolio assessment. An analyzed mean of 
the misconception analysis of less than 3.50 was interpreted as miscon-
ception (according to Waedramae’s (2004) study on the analysis of mis-
conceptions in educational quality assessment), whereas the analyzed 
mean of the current performance rating in implementing student port-
folio assessment was interpreted by following the labels (i.e., 4.50 - 5.00 
= very high, 3.50 - 4.49 = high, 2.50 - 3.49 = medium, 1.50 - 2.49 = low, 
and 1.00 - 1.49 = very low). In addition, independent-sample t-test was 
also used to compare teachers’ current performance in implementing 
student portfolio assessment between teachers who had attended the 
training sessions concerning student portfolio assessment and those 
who had not. 

RESULTS

Teachers’ Misconceptions in Implementing Student Portfolio 
Assessment

Teachers’ misconceptions in implementing student portfolio assess-
ment, measured by using the five-point rating scale, were as shown in 
Table 1. Overall, teachers (combining those who had attended the train-
ing sessions concerning student portfolio assessment with those who 
had not) had misconceptions in nine concepts (six concepts were about 
the principles of student portfolio assessment and three concepts were 
about the utilization of the results from student portfolio assessment). 
The most important teachers’ misconception concerning the principles 
of student portfolio assessment was: (a) portfolio is a container of all of 
the exercises done by students in a whole course (M= 2.24, SD=1.00); 
followed by (b) the same format of portfolios (e.g., an introduction 
part, a table of contents) should be set among students to follow the 
same standards (M= 2.35, SD=1.01); (c) portfolio must only be used to 
assess students’ learning separately for each course (M= 2.41, SD=1.08); 
(d) portfolio must only be used in a course that assigns students to

45

create learning products (M= 2.58, SD=1.05); (e) portfolio is consistent 
with a lecture style instruction method (M= 2.94, SD=1.06); and (f ) it is 
not necessary that teachers plan the learning activities at the begin-
ning of the courses (M= 3.31, SD=1.18). As for the misconceptions about 
the utilization of the results from student portfolio assessment, it was 
found that the most important misconception was: (a) after finishing the 
portfolio process, teachers should keep all of the students’ portfolios to 
reflect the quality of their teaching (M= 2.28, SD=1.98); followed by (b) 
portfolio is better used for summative assessment rather than formative 
assessment (M= 2.90, SD=1.04); and (c) portfolio is a supplementary as-
sessment method, therefore it is not necessary to utilize the results from 
portfolio assessment (M= 2.83, SD=1.07), respectively. As for consider-
ing each group of participants, it was also found that teachers in both 
groups had the same misconceptions about the principles of student 
portfolio assessment and the utilization of the results from student port-
folio assessment as mentioned earlier. The above results are consistent 
with the results on the misconceptions of teachers who had attended 
the training sessions and those who had not attended the training ses-
sions. 

A two-way analysis of variance with repeated measure on one factor 
was also performed to compare teachers’ score on the misconception in 
implementing student portfolio assessment between two groups. The 
independent factor was group (teachers who had attended the train-
ing sessions concerning student portfolio assessment and those who 
had not), and the repeated-measure factor was teacher’s score on the 
misconception in implementing student portfolio assessment in two 
aspects [(a) principles of student portfolio assessment, and (b) utiliza-
tion of the results from student portfolio assessment]. A teacher’s score 
for each of the two aspects was calculated by averaging the two ratings 
of survey items corresponding to each aspect. It was found that overall 
mean ratings of teachers’ scores on the first aspect of misconception 
(principles) in implementing student portfolio assessment by teachers 
who had attended the training sessions concerning student portfolio 
assessment and those who had not were not statistically significant 
different, F(1,452) = 0.04, p > .05. Moreover, there was no statistically 
significant difference between the mean ratings of the teachers’ scores 
on the second aspect of misconception (utilization) in implementing

student portfolio assessment, F(1,452) = 0.01, p > .05. It was also found 
that there was no significant interaction effect between the group fac-
tor and the aspect of misconception factor, F(1,452) = 0.90, p > .05. 

The independent-sample t-test was employed to compare teach-
ers’ scores on the misconception in implementing student portfolio 
assessment between teachers who had attended the training sessions 
concerning student portfolio assessment and those who had not. It was 
found that, mostly, the two groups of teachers did not have significant 
differences in the misconception scores. Among the few significant dif-
ference findings, the most notable is that there was one concept (i.e., 
the same format of portfolio should be set among students to follow the 
same standards) that teachers had not attended the training sessions 
had more misconception than those who had attended the training ses-
sions (t= 2.73, p<.01).

Teachers’ Current Performance in Implementing Student 
Portfolio Assessment 

Teachers’ current performance in implementing student portfolio 
assessment is as shown in Table 2 and Figure 1. It was found that overall 
(combining teachers who had attended the training sessions concern-
ing student portfolio assessment and those who had not), teachers 
implemented the four main steps of student portfolio assessment at a 
medium to high level. The step of planning for portfolio assessment and 
the step of collecting created products were implemented at a high level 
(M=3.50, SD=0.82 and M=3.52, SD=0.93, respectively), whereas the step 
of selecting products and reflecting on the selected products as well 
as the step of revising and evaluating products were implemented at 
a medium level (M=3.34, SD=0.95 and M=3.39, SD=0.96, respectively). 
For the current performance of teachers who had attended the train-
ing sessions concerning student portfolio assessment, it was found that 
teachers also implemented the four main steps of student portfolio as-
sessment at a medium to high level. The step of planning for portfolio 
assessment, the step of collecting created products, as well as the step 
of revising and evaluating products were implemented at a high level 
(M=3.58, SD=0.79; M=3.66, SD=0.88, and M=3.52, SD=0.92, respectively), 
whereas the step of selecting products and reflecting on the selected 
products were implemented at a medium level (M=3.49, SD=0.90). As 
for the current performance of teachers who had not attended the train-
ing sessions concerning student portfolio assessment, it was found that 
teachers implemented the four main steps of student portfolio assess-
ment [(a) planning for portfolio assessment, (b) collecting created prod-
ucts, (c) selecting products and reflecting on selected products, and (d)

revising and evaluating products] at a medium level (M=3.43, SD=0.84; 
M=3.39, SD=0.96; M=3.20, SD=0.97; and M=3.26, SD=0.97, respectively)

A two-way analysis of variance with repeated measure on one factor 
was also performed to compare teachers’ current performance in imple-
menting student portfolio assessment between two groups. The inde-
pendent factor was group (teachers who had attended the training ses-
sions concerning student portfolio assessment and those who had not), 
and the repeated-measure factor was teachers’ current performance in 
implementing student portfolio assessment [(a) planning for portfolio as-
sessment, (b) collecting created products, (c) selecting products and re-
flecting on selected products, and (d) revising and evaluating products]. 
A teacher’s score for each of the four performances was calculated by 
averaging the various ratings of survey items corresponding to each per-
formance. It was found that overall mean rating of teachers’ performance 
in implementing student portfolio assessment by teachers who had at-
tended the training sessions concerning student portfolio assessment and 
those who had not were statistically significant different, F(1,452) = 8.94, p 
< .01. Moreover, there was a statistically significant difference among the

four mean ratings of the performance of teachers in implementing stu-
dent portfolio assessment, F(3,1356) = 29.76, p < .01. It was also found that 
there was a significant interaction effect between the group of teachers 
and their student portfolio assessment performance, F(3,1356) = 3.04, p < 
.05. A simple effect analysis following significant interaction indicated sig-

ing in all four performances except “Planning” performance--(a) Planning,

ing, F(1,557) = 10.83, p = .001; (d) Revising, F(1,557) = 8.95, p = .003.

The independent-sample t-test was employed to compare teachers’ 
current performance in implementing student portfolio assessment be-
tween teachers who had attended the training sessions concerning stu-
dent portfolio assessment and those who had not. It was found that, over-
all, teachers who had attended the training sessions performed at a higher 
level in implementing the four main steps of student portfolio assessment 
than those who had not. However, it is noted that the two groups of teach-
ers did not have significant differences in performing some activities in 
the four main steps of portfolio assessment, i.e., (a) reviewing the learning 
standards and indicators of the courses, (b) identifying numbers of prod-
ucts required to produce in the courses, (c) informing students at the be-
ginning of the courses about the use of student portfolio assessment, (d) 
allowing students to participate in setting the purposes of creating port-
folios, (e) encouraging students to collect their created products in their 
working folders, and (f ) providing students with opportunities to revise or 
improve the products/evidence in their portfolios.

DISCUSSION

Teachers’ Misconceptions in Implementing Student Portfolio 
Assessment

The results of this study revealed that teachers in both groups had 
misconceptions in nine concepts concerning the principles of student 
portfolio assessment and the utilization of the results from student port-
folio assessment. The most serious misconception concerning the prin-
ciples of student portfolio assessment was that the portfolio is a con-
tainer of all of the exercises done by students in a whole course. This 
is the most common misunderstanding among Thai teachers. The Thai 
teachers, generally, probably view that the portfolio is merely used to

55

keep all students’ works together so that they do not get lost. Therefore, 
they do not pay enough attention to other steps of portfolio assess-
ment, especially the reflection step which is essential. This is consistent 
with the finding of Saypetch’s (2003) study which revealed that teachers 
had difficulties at the moderate level in monitoring students to reflect 
on their opinion of the products or artifacts in their own portfolios and 
to revise their products or artifacts in their own portfolios. Tangdhana-
kanond & Wongwanich (2012) also found that teachers had most critical 
needs in the use of student portfolio assessment in the step of select-
ing products and reflecting on the selected products, respectively. As 
for the misconception about the utilization of the results from student 
portfolio assessment, it was found that Thai teachers perceived portfolio 
to be better used for summative assessment than formative assessment. 
That resulted in teachers not putting enough emphasis on some impor-
tant activities that provide students with learning feedback, such as en-
couraging students to do self-assessment, allowing students to revise 
the products in their portfolios. It was also found that overall, the two 
groups of teachers did not have significant differences in the miscon-
ception scores. This indicated that the current training sessions concern-
ing portfolio assessment could not change teachers’ misconceptions in 
this regard. The findings of this study could help related public sectors 
and personnel such as supervisors from the Ministry of Education and 
teacher trainers from universities change teachers’ misconceptions on 
the issues more effectively. 

Teachers’ Current Performance in Implementing Student 
Portfolio Assessment 

The findings of this study indicated that, overall, teachers in both 
groups (combining those who had attended the training sessions con-
cerning student portfolio assessment and those who had not) imple-
mented the four main steps of student portfolio assessment at a me-
dium to high level. The step of planning for portfolio assessment and the 
step of collecting created products were implemented at a high level, 
whereas the step of selecting products and reflecting on the selected 
products as well as the step of revising and evaluating products were 
implemented at a medium level. This is consistent with the previous 
finding of this study that teachers had a misconception that portfolio

56

is better used for summative assessment rather than formative assess-
ment. Therefore, they perform the step of selecting products and reflect-
ing on the selected products as well as the step of revising and evaluat-
ing products merely at a medium level – not at a high level. The finding is 
also consistent with other previous research studies (Tangdhanakanond 
& Wongwanich, 2012; Tangdhanakanond & Wongwanich, 2015). It is also 
consistent with results from the study by Sripijitworasakul and Tangd-
hanakanond (2012), which indicated that the step of revising products, 
as well as the step of self-assessment and revising products was less fre-
quently implemented by Thai language teachers. Similar findings were 
found in a previous research study of Kornketkamon (2001) which found 
that teachers had problems in some activities, such as giving students as 
well as parents a chance to express their opinion on students’ artifacts. In 
addition, the present research findings are also consistent with research 
by Srirod (2002) which found that teachers have some difficulties in 
guiding students in selecting products for their portfolios, encouraging 
students to reflect on their products, as well as guiding them to evaluate 
their products and learning. Actually, those two steps (revising and eval-
uating products, as well as selecting products and reflecting on the se-
lected products) are crucial to develop students’ learning. While students 
are revising and evaluating the products in their portfolios, they could 
examine their strengths and weaknesses reflected by the quality of their 
products, as well as take responsibility for their own learning (Priest & 
Robert, 1998 as cited in McMullan, 2006; Tangdhanakanond, 2006; Tang-
dhanakanond, 2016; Tangdhanakanond & Wongwanich, 2015).

It was also found that, overall, the performance in implementing the 
four main steps of student portfolio of teachers who had attended the 
training sessions concerning student portfolio assessment was higher 
than those who had not attended training sessions. Teachers who had 
attended the training sessions had more opportunities to learn about 
the portfolio assessment process. Therefore, they performed the four 
main steps of student portfolio assessment at a higher level than the 
other group. However, it is noted that the two groups of teachers did not 
have significant differences in performing some specific activities in the 
four main steps of portfolio assessment, i.e., (a) reviewing the learning 
standards and indicators of the courses, (b) identifying numbers of prod-
ucts required to produce in the courses, (c) informing students at the 



2019, 23, 39–62 p.Misconceptions And Current Per formance In Por tfolio Assessment

57

beginning of the courses about the use of student portfolio assessment, 
(d) allowing students to participate in setting the purposes of creating 
portfolios, (e) encouraging students to collect their created products in 
their working folders, and (f ) providing students with opportunities to 
revise or improve the products/evidences in their portfolios. That could 
be because those six activities are basic to the portfolio process and 
well-known among teachers in both groups. Therefore, teachers in both 
groups perform those activities equally well. It is also interesting to note 
that the only step of the portfolio process that teachers in both groups 
performed differently in every specific activity was the step of selecting 
products and reflecting on selected products, which is a very important 
step in the portfolio process (Tangdhanakanond & Wongwanich, 2015; 
Pasiphol, Koraneekij, & Sotthayakom, 2015; Tangdhanakanond & Wong-
wanich, 2012; Pearson Education Development Group, 2001; Poowi-
padawat, 2001; Prawarnpruek, 1997; Punngam, 2000; Saereerat, 1997; 
Siladech, 1997). This should not be surprising considering the fact that 
teachers who had attended the training session had more opportunities 
to learn and practice the complete process and the crucial step of the 
portfolio assessment. 

Further Consideration

Only elementary school teachers were studied in this study. Further 
research with middle and high school teachers should be conducted. Ex-
amining their misconceptions and current performance in implement-
ing student portfolio assessment would also be a helpful plan for chang-
ing the misconceptions of middle and high school teachers in this issue 
in the future. 

CONCLUSION

The key concept in the present study (Portfolio Assessment) is an 
important topic in the field of Educational Psychology. As shown in the 
definition of “Educational Psychology” given by Ausubel, Novak, and 
Hanesian (1978), evaluation (or assessment) of school learning is an im-
portant area in the field of educational psychology. The purposes of this 
study were (a) to examine teachers’ misconceptions in implementing 



Kamonwan Tangdhanakanond, Teara Archwamety

58

student portfolio assessment, and (b) to compare teachers’ current per-
formance in implementing student portfolio assessment between teach-
ers who had attended the training sessions concerning portfolio assess-
ment and those who had not. Results revealed that, overall, teachers had 
misconceptions in nine concepts. Six concepts were about the principles 
of student portfolio assessment and three concepts were about the uti-
lization of the results from student portfolio assessment. Performance 
which consisted of implementing four main steps of student portfolio 
assessment was higher for teachers who had attended the training ses-
sions concerning student portfolio assessment than for those teachers 
who had not attended the training sessions. Findings on teachers’ mis-
conceptions and current performance of student portfolio assessment 
could help related public sectors and personnel such as supervisors from 
the Ministry of Education and teacher trainers from universities change 
teachers’ misconceptions on the issues more effectively in the future. In 
this study, only elementary school teachers were studied. Middle and 
high school teachers should be studied in further research.

Santrauka. Priėmus nacionalinį švietimo aktą B.E. 2542, Tailande mokytojams siūloma tai-
kyti įvairius mokinių vertinimo metodus, taip pat ir portfolio. Mokinių portfolio meto-
das – sisteminis įrodymų, kaip jiems sekasi mokytis ir ko yra pasiekę įvairiose srityse, 
rinkinys. Šio tyrimo tikslai – įvertinti klaidingus mokytojų įsitikinimus, susijusius su 
mokinių vertinimu portfolio metodu, taip pat palyginti mokytojų, kurie lankė portfolio 
metodo įgyvendinimo mokymus ir kurie juose nedalyvavo, portfolio metodo taikymo 
patirtį. 454 pradinių mokyklų mokytojai buvo atsitiktinai atrinkti dalyvauti šiame tyri-
me. Klausimynai buvo naudojami siekiant surinkti informaciją apie mokytojų klaidin-
gus įsitikinimus taikant portfolio principus mokiniams vertinti. Taip pat klausimynu

buvo vertinama, kiek mokytojai naudoja keturis portfolio metodo žingsnius: a) por-
folio vertinimo planavimas, b) atliktų užduočių rinkimas, c) užduočių parinkimas ir 
refleksija jų atžvilgiu, d) užduočių peržiūra ir įvertinimas. Tyrimo rezultatai atskleidė, 
kad mokytojai turi klaidingų įsitikinimų devyniose srityse. Šešios iš jų susijusios su 
portfolio vertinimo principais ir trys – su vertinimo rezultatų panaudojimu. Mokyto-
jai, kurie buvo mokomi naudoti portfolio vertinimo metodą, geriau taikė keturis šio
