Science is an essential social institution and a building block in advancing human 
societies. At the core of scientific discovery 
and problem solving is innovation to improve 
the human condition, within and beyond the 
institutions of higher education that shape sci-
entific minds. Research in any field, beginning 
in undergraduate education, is fundamentally 
about information—finding, understanding, 
generating, discussing, influencing, contradict-
ing, contextualizing, disproving, and communi-
cating it; the ability to do so generally referred 
to as information literacy.1 Parallel to this, 
everyday life increasingly requires navigating 
an overwhelming amount of complex scientific 
information, and misinformation. 

There has been a long-standing assump-
tion by professors that many students enter 
into college tech-savvy, and, adjacent to 
those skills, there is an assumption they are 
able to navigate information seeking in the 
same way.2,3 Similarly students are overcon-
fident in their abilities to find information, 
which has often been experienced by us 
hearing students say, “We’ll just Google it” 
as a benchmark for how they find what they 
perceive as good information. Parallel to this, 
in the applied sciences, like engineering, we 
have experienced a disconnect in perception 
around what we understand as necessary 
foundational information to practice, and 
what students perceive research necessary 
to make decisions.4 

When students begin college in science 
disciplines, they often arrive without mean-

ingful experience finding or using primary 
scientific literature and with engrained, yet 
underdeveloped, information-seeking be-
haviors built from prior experiences in high 
school classrooms and daily life.5 Many 
engineering students are focused on their 
professional future, and therefore do not 
understand the need to learn to research, 
since their goal is not to be an academic. Ef-
fective communication around professional 
responsibilities of finding and using informa-
tion is equally important to communicating 
information literacy skills. 

Training STEM students to properly 
navigate the current information landscape 
is foundational to their academic and profes-
sional success. The social and academic role 
of information seeking in science education 
is often taken for granted, and frequent as-
sumptions are made around how, when, and 
where science, technology, engineering, and 
mathematics (STEM) students are finding 
scientific information. Receiving even less 
consideration is the learning required to ac-
curately contextualize information within the 
current environment of overload, saturation,

and misinformation. Professors often think 
about teaching the specific subject of their 
discipline, and often teaching students ten-
ants around information-seeking and literacy 
is left out of traditional science courses.6 

Information literacy, though a term used 
widely in the library context, has failed to 
effectively resonate within the academic 
discourse in the STEM fields.7,8 Within STEM, 
there is an abundance of terms used for the 
concept ranging from science communica-
tion and data information literacy9 to sci-
ence media education10 and STEM literacy 
for learning.11 This indicates that while the 
ideals of information literacy are important to 
the STEM fields, the lack of consensus around 
terminology limits effective discussion and 
educational intervention. This absence of 
consensus is compounded by the concern 
that information literacy rarely resonates 
with STEM faculty, a gap STEM librarians 
face with communicating and supporting 
science faculties due to less than 30% of 
STEM librarians having a subject-specific 
degree, and the implicit connection of the 
term literacy exclusively with books.12 Sci-
ence faculty members and students often 
come from academic cultures that rely heavily 
on in-lab or personal networks and profes-
sional associations for much of their own 
information seeking.13,14,15 Finding the right 
terminology to connect with faculty helps 
open the conversation to the library’s value 
in supporting STEM research by placing our 
skills within the scientific scope.

In the health disciplines, the use of in-
formation for clinical decision-making is 
core to professional practice and research. 
Called critical appraisal, health fields use 
a systematic process to delineate strengths 
and weaknesses of research while ascer-
taining the applicability and validity of the 
content to the research or clinical task.16 
Critical appraisal at its core is the process of 
systematically assessing scientific evidence 
to judge its trustworthiness, value, and rel-
evance.17 Traditional critical appraisal tools 
evaluate information by asking “Does the 
study address a clear question? Does it use 

valid methods? Are they applicable to the 
population in question?”18 Readers are further 
encouraged to examine whether the research 
question is important, analysis is appropriate, 
and conflicts of interest are transparent. This 
question-based evaluation approach aligns 
closely with information evaluation models 
used in information literacy instruction, 
such as RADAR19 or CRAAP.20,21 The process 
asks individuals to probe evidence using a 
questioning approach, including the need to 
establish the relevance of any information 
consulted to the task at hand, an issue that 
Michael J. Carlozzi22 establishes as lacking in 
student information synthesis. 

Critical appraisal is taught to students in 
healthcare professions through curriculums 
that incorporate evidence-based practice.23 

As an example, first-year pharmacy students 
at the University of Waterloo complete a 
required drug information fundamentals 
course, cotaught by the librarian and pro-
fessor, dedicated to finding, interpreting, 
evaluating, and applying health research. 
This course was developed through librarian 
and faculty collaboration, and favors the use 
of the term critical appraisal versus the term 
information literacy, as the course places 
emphasis on the importance of acquiring 
the skills necessary to assess the validity of 
information found on the Internet and in the 
published research. In addition to critiquing 
the published research, students are tasked 
with critically evaluating the credibility of a 
website related to opioid prescribing, draw-
ing from the RADAR24 approach. 

Using the pharmacy course as a guide-
line, in 2017, engineering librarians at the 
University of Waterloo adapted key elements 
from this course into a single lesson for a 
required first-year engineering communica-
tions course, followed in 2018 with a similar 
course for first-year science students led by 
the science librarians. Likewise, the focus 
of these two lessons was on giving students 
tools to acquire the skills they need to assess 
the validity of information they find, regard-
less of the source. Through field-specific 
examples, we have successfully approached

contextualizing research within the context 
of being a professional engineer, aligning it 
with expectations of engineering professional 
practice to find, use, and share ethically sound 
information. For the science students, the librar-
ians focus on the students becoming effective 
scientists—you need to be able to understand 
not only the lab-based experiments, but also to 
understand the process through which scientific 
discovery has happened.

In the engineering courses, we introduce 
students to critical appraisal, through the RA-
DAR framework and use this approach to eval-
uate both an online source and an academic 
article that they find, around an engineering 
topic of their choosing. In the science courses, 
framing the topic as critical appraisal gives 
students a framework for finding and contex-
tualizing information as part of building their 
understanding of science. With this in mind, 
we introduce these skills through interactive 
lecture and discussion and then reinforce them 
through a RADAR activity, where students must 
appraise a librarian-provided peer-reviewed 
article. Both of the activities focus on critiqu-
ing the information students are using to 
demonstrate that ease of availability does not 
equate accuracy or credibility, while offering 
opportunity for the approach to be scaffolded 
throughout the curriculum. For example, in 
one of the engineering programs, the librarian 
works with professors through each year on 
increasing levels of critical appraisal through 
design projects in the curriculum. 

As interventions are further developed, 
within one program we see significant po-
tential to implement broadly across other 
programs, and is currently being adapted for 
mathematics students. By using the term criti-
cal appraisal and having students draw their 
own conclusions when working through the 
RADAR framework, we have seen some suc-
cess in navigating students away from online 
search engines and towards scholarly materials 
with a more open mind. 

Moreover, this strategy has been extremely 
effective in working with STEM faculty to 
integrate into the curriculum. It has opened 
conversations around the role and importance 

of the librarian and the value of active assess-
ment of resources used by students. Because 
critical appraisal at its core is a process, it is 
readily adaptable for nonacademic literature 
that must be evaluated for use in the design 
process for engineering fields and technical 
documentation prevalent in science and tech-
nology. Furthermore, because the method of 
evaluation aligns with existing approaches 
used in the library field, there is a significant 
body of resources that can help librarians 
make the shift to critical appraisal without 
radically redesigning classroom activities and 
approaches.

For education to be effective, it must meet 
individuals where they are and build from 
their existing knowledge base. Using the 
terminology critical appraisal allows librar-
ians, particularly those who support STEM 
disciplines, to more effectively open discus-
sions around information literacy. Though 
seemingly insignificant, changing our rhetoric 
from information literacy to critical appraisal 
has had a huge impact on our ability to con-
nect with STEM faculty and students. Using an 
established process that is validated in health 
research (and therefore aligns with the scien-
tific method) moves STEM students away from 
literacy and its connotation with their ability 
to read books, and towards a critical mindset 
around information. As librarians seek to ef-
fectively communicate value in the modern 
academic landscape, we must align our efforts 
with established processes and perceptions of 
science faculty and learners to foster innova-
tion and drive scientific discovery.
