KLEWS Chart’s Contribution to Promoting Students’ Creativity in STEM
Education with the Topic Optics

This study demonstrates that the KLEWS teaching technique is effective in
developing students’ creative abilities in STEM education with the subject
of Optics. The KLEWS chart allows students to practice logical and
argumentative thinking based on scientific information and evidence.
Furthermore, teaching according to KLEWS chart stimulates students’
curiosity, imagination, creativity, and desire to learn more about science.
The mixed methods research was carried out on 161 eleventh grade students
in Vietnam (including 80 students in the control group and 81 students in
the experimental group). The research evaluates students’ creative abilities
by observing students’ creative expression in normal STEM’s topics
without KLEWS chart in each group. Then, for the experimental group,
organize teaching STEM topics using the KLEWS chart, and for the control
group, organize teaching the topics of normal STEM. The results showed
that the experimental group reached a high level of creativity (7.77/10
points), while the control group had a medium level of creativity (4.81/10
points). In addition, the research found that students were excited and active
in STEM activities; applied the KLEWS chart to explore knowledge of
STEM topics; confidently made a presentation and had the ability to use the
keywords and scientific terms listed in the KLEWS chart and link them
together. The findings of this study will help to clarify the effectiveness of
developing students’ creative capacity in STEM education using the
KLEWS chart
