Abstract

Misconceptions in physics represent a persistent barrier in students’ learning processes, influencing how they interpret and apply fundamental principles. These misconceptions are often robust, deeply rooted in everyday experiences, cultural beliefs, or misleading linguistic expressions, making them resistant to traditional forms of instruction. The present study aims to map senior high school students’ misconceptions across a wide range of core physics topics—including mechanics, energy, waves, and optics—through a qualitative lens. The research employed a four-tier diagnostic test and semi-structured interviews administered to 45 eleventh-grade students from a public high school in South Tangerang, Indonesia. The diagnostic test allowed for the identification of misconceptions by probing students’ answers, reasoning, confidence levels, and justifications, while follow-up interviews provided deeper insights into students’ thought processes. Data were analyzed thematically to classify the most dominant misconceptions and to uncover the underlying reasoning patterns that sustain them. Findings revealed that the most prevalent misconceptions were associated with Newton’s third law, where students believed that action and reaction forces cancel each other out; with energy conservation, where energy was perceived as a consumable entity that “runs out”; with sound propagation, where students assumed sound could travel in a vacuum; and with optics, particularly shadow formation, where students believed that light rays could stop or bend arbitrarily in space. These misconceptions were not isolated errors but rather formed coherent alternative frameworks that strongly influenced students’ conceptualizations. The implications of this study are twofold. First, mapping misconceptions across different physics domains provides a comprehensive overview of the conceptual challenges faced by students, which can inform teachers’ pedagogical strategies. Second, the results emphasize the need for instructional approaches that combine multiple representations—verbal, graphical, and experimental—along with inquiry-based activities that explicitly challenge students’ existing ideas. Such approaches are expected to foster conceptual change and support students in developing a more scientifically accurate understanding of physics.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh bentuk lintasan terhadap waktu tempuh benda yang meluncur pada bidang miring tanpa gesekan. Dua jenis lintasan dibandingkan, yaitu lintasan lurus dan lintasan bergelombang. Metode penelitian yang digunakan adalah kajian teoritik dengan pendekatan hukum kekekalan energi serta perhitungan analitik dan simulasi numerik sederhana untuk menentukan waktu tempuh pada setiap lintasan. Lintasan bergelombang dimodelkan menggunakan fungsi sinusoidal dengan variasi amplitudo dan frekuensi gelombang. Hasil perhitungan menunjukkan bahwa beberapa lintasan bergelombang dapat menghasilkan waktu tempuh lebih singkat dibandingkan lintasan lurus karena memberikan percepatan awal yang lebih besar. Namun, jika gelombang terlalu curam atau rapat, waktu tempuh justru menjadi lebih lama. Temuan ini menunjukkan bahwa bentuk lintasan berpengaruh terhadap efisiensi gerak benda dan dapat digunakan sebagai contoh penerapan konsep energi dan kalkulus variasi dalam pembelajaran fisika.

Abstract

The distinction between heat and temperature is fundamental in physics learning, yet it remains a persistent source of student misconceptions. Many learners interpret heat as a tangible substance stored within an object or assume that temperature is equivalent to the amount of heat possessed. Such misunderstandings hinder the development of deeper concepts in thermodynamics and energy transfer. This study aims to investigate senior high school students’ conceptual understanding of heat and temperature through a qualitative lens. The research involved 30 Grade XI students from a public high school in Indonesia. Data were collected using a conceptual diagnostic test followed by semi-structured interviews that probed students’ reasoning about everyday thermal phenomena. Thematic analysis was applied to categorize misconceptions and identify underlying reasoning models. Findings revealed four dominant patterns: (1) the substance model of heat, where students described heat as a material that flows from hot to cold bodies; (2) the equation model of temperature, in which temperature was mistakenly treated as the total amount of heat; (3) the cold transfer misconception, where students believed coldness itself moves from one body to another; and (4) the size–temperature confusion, where larger objects were assumed to always have higher temperature. These conceptions align with reports in international literature, indicating the universal nature of such difficulties. The study underscores the value of qualitative exploration for uncovering the reasoning behind misconceptions, not merely their frequency. Implications for teaching include the use of particle-level representations, predict–observe–explain activities, and simple calorimetry experiments to help students reconstruct scientifically accurate models of heat and temperature.

Abstract

Misconceptions The study of heat conduction has long been a central topic in applied mathematics and physics, providing fundamental insights into the diffusion of thermal energy across various media. This research focuses on solving the one-dimensional heat conduction equation using Fourier analysis as a mathematical tool to obtain an exact solution under specified boundary and initial conditions. By applying separation of variables and Fourier series expansion, the temperature distribution of the rod is represented as an infinite series that converges to the exact solution. To validate the analytical solution, a numerical simulation based on the finite difference method is also performed, allowing comparison of accuracy and convergence. The results show that Fourier analysis provides a reliable and elegant framework to model heat conduction problems, with numerical methods serving as a complementary approach for cases where closed-form solutions are intractable. This study highlights the significance of Fourier techniques not only in mathematical physics but also in practical applications such as material science and thermal engineering.

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.

Abstract

Energy conservation is a fundamental principle in physics, yet numerous studies report that students often hold misconceptions regarding its meaning and application. This study aims to qualitatively explore senior high school students’ misconceptions about the conservation of energy in mechanical systems. Data were collected from 36 students in grades X and XI using a four-tier diagnostic test combined with semi-structured interviews. Thematic analysis was employed to identify the types and patterns of misconceptions. Results indicate that students frequently perceive energy as a consumable entity that disappears during processes involving friction, or equate kinetic energy directly with force. Other misconceptions include the belief that energy can be permanently lost in non-conservative systems and that potential energy does not exist unless motion occurs. These findings highlight persistent gaps in conceptual understanding despite formal instruction. The study suggests that explicit teaching strategies, such as conceptual change approaches and multiple representations, are required to address these alternative conceptions.
