Abstract

Newtonian mechanics remains a fundamental yet conceptually challenging domain for high school students. Numerous studies have shown that students consistently hold alternative conceptions that contradict scientific understanding, particularly in relation to Newton’s laws of motion. This study aimed to explore senior high school students’ misconceptions in Newtonian mechanics through a qualitative investigation. Data were collected from 28 Grade 11 students in an Indonesian high school using open-ended diagnostic tests, semi-structured interviews, and classroom observations. Thematic coding identified four major categories of misconceptions: inertia, force–motion relationships, action–reaction interactions, and free-body diagram representations. Among these, misconceptions of Newton’s third law were the most dominant, with the majority of students believing that the object with greater mass exerts a greater force during interaction. Inertia misconceptions, such as the belief that motion requires continuous force, were also widespread. The findings confirm that students’ misconceptions are robust cognitive frameworks reinforced by everyday experiences and traditional teaching practices. Pedagogically, the results highlight the importance of incorporating inquiry-based learning, multiple representations, and cognitive conflict strategies to promote conceptual change. This study contributes to the literature on physics education by providing context-specific insights into persistent misconceptions in Newtonian mechanics and suggesting implications for more effective teaching practices.

Abstract

This study explores senior high school students’ misconceptions of light and shadow formation within the context of physics education. Despite being a fundamental concept in optics, many students continue to experience difficulties in understanding the principles of light propagation, the rectilinear nature of light, and the conditions required for shadow formation. This research employed a qualitative exploratory design involving 32 students from Grade X and XI science classes in Central Java, Indonesia. Data were collected through diagnostic tests and semi-structured interviews, which allowed in-depth identification of alternative conceptions. The analysis revealed three dominant categories of misconceptions: (1) perceiving light as a substance that “flows” from the source, (2) assuming that shadows are independent objects rather than regions of blocked light, and (3) misunderstanding the relationship between light intensity, distance, and shadow clarity. These findings confirm that students often rely on intuitive reasoning based on everyday experiences rather than scientific explanations. The discussion highlights the implications for physics instruction, particularly the need for teaching strategies that incorporate conceptual change models and inquiry-based learning to address students’ alternative frameworks. The study concludes that addressing misconceptions in optics requires not only emphasizing correct scientific principles but also engaging students in reflective and interactive learning processes that directly confront their prior conceptions.
