An analysis of student’s concepts understanding about simple harmonic motion: Study in vocational high school

Abstract

Abstract This study presents an analysis of the student’s concept of understanding about simple harmonic motion in vocational high school. The sample of the study consisted of 76 vocational high school students 1 Mondokan. The two-tier research instrument used to measure students’ understanding of concepts. The category of concept understanding assessment based on concept understanding indicators, i.e., no understanding, specific misconception, partial understanding with a specific misconception, partial understanding, and sound understanding. The results of the analysis of the quality of the instrument indicate the value of person reliability of 0.82, and item reliability of 0.76 is in a good category. The results showed that specific misconception was 14.6%, partial understanding with a specific misconception was 23.9, partial understanding 36.8%, and sound understanding 24.7%. These findings indicate the need to empower students’ understanding of concepts, using instructional media that can visualize abstract concepts of simple harmonic motion.
