| Abstract: | Effective physics instruction should deepen students' understanding of core concepts and strengthen their ability to communicate scientific ideas. This is an exploratory empirical study based on a lab session on drag force - a key topic for future engineers. In addition to video analysis of an object falling under drag, student teams discussed and sketched their ideas in response to motion-related prompts. We qualitatively analyzed transcripts and sketches from 13 teams, exploring the conceptual and reasoning resources students employ. Students used a range of physics and mathematical ideas, including momentum, energy, kinematics, and experimental graphs. We identified both productive and unproductive uses of these resources. Our findings emphasize the need for iterative, data-informed instructional materials that support deeper engagement with conceptual resources in physics and mathematics. |
