Psychometric Properties of Computational Thinking Using Artec-Robo for STEM Education

Abstract

Science, Technology, Engineering, and Mathematics (STEM) is part of the 21st Century curriculum
that promoting Computational Thinking. Various curriculum activities are still conducting using robotics to
promote STEM education among students. Therefore, Artec-Robo is playing a crucial role in fostering
Computational Thinking through STEM Education. This study aims to develop and validate instruments to
measure teachers' perceptions of Computational Thinking Using Artec-Robo for STEM Education (CTARS). A
total of 15 items was produced by using the literature review. As for the sample of this study, 33 educators who
attended a workshop on Computational Thinking Using Artec-Robo for STEM education had participated in
this study. The instrument was validated by three experts. The data was analyzed using Partial Least Square
(PLS), Structural Equation Modeling (SEM). The exploratory factor analysis (EFA) was run to confirm that the
data support the selected scale for the present study. The findings of the study revealed that the CTARS
instrument is valid and reliable, with a Cronbach's alpha value of 0.889. Besides, the results also informed that
the total variance extracted by the items within the constructs was 62.23%. The Artec-Robo plays a great role in
promoting Computational Thinking in STEM education. The CTARS instrument contributes to the knowledge
of literature for future researchers.
