Abstract

One of the physics matter that is considered difficult by high school students is the concept of collision in which discuss the coefficient of restitution (e). On that basis, the restitution coefficient becomes one of the studies discussed in Physics Depth II for pre-service physics teacher in one of LPTK in West Java. This paper describes the profile of pre-service physics teacher in understanding the physical meanings of restitution coefficients, how to write mathematical formulas and the appropriate didactic reduction in learning the concept of restitution coefficients in high school students. The population of this research is pre-service physics teacher in one of LPTK in West Java, while the sample is 80 pre-service physics teacher who has taken the subject of Physics Depth II. By using cross-sectional survey method, it was found that (1) the number of respondents who answered the physical meaning of the restitution coefficient in the right category were: 39.7%, the less appropriate category was 22% and the rest of the category was not exactly 38.3%. (2) The mathematical formula of the selected restitution coefficient is 91.3% using TYPE B1, 2.8% using TYPE B2 and the remaining 5.7% using TYPE B4. (3) The didactic reduction chosen by the respondents in learning the concept of restitution coefficient in high school students is 10.2% by returning to the qualitative mean, 66.7% using drawings and sketches, 20.3% using analogy, while the rest using particularization (1.4%) and generalization (1.4%).

Abstract

The study aimed to analyze the thematic focus and review the literature on the implementation of inclusive STEM education to enhance student participation in learning, as well as to address four research questions of the STEM education system, inclusive teaching practices, the principles of diversity, equity, and inclusion (DEI), and access to quality education. The particular study integrated bibliometric analysis (BA) and a systematic literature review (SLR). Article metadata from Scopus was extracted on December 7, 2025, and rigorously selected using the PRISMA 2020 protocol. Applying specific inclusion and exclusion criteria to ensure the study’s relevance and depth yielded 52 core journal articles that published between 2021 and 2025. The analysis identified four thematic clusters: the STEM learning system, inclusive teaching, diversity, equity, and inclusion (DEI), and access to quality education. The synthesis indicates that students’ participation in inclusive STEM learning is shaped by a student-centered, contextual, flexible, and collaborative system design; inclusive pedagogy through differentiation, a safe classroom climate, and equitable formative assessment; the application of DEI principles; and support for access to quality education through institutional support and a transformation of the learning culture.
