Challenges in Learning Physics: Conceptual Reasoning vs. Math
Physics poses challenges to learners not just due to the complexity of math involved, but primarily because of the struggle with conceptual reasoning. The mismatch between our intuitive understanding acquired from everyday experiences and the scientific principles of physics creates hurdles. Students often reason like Aristotle, with misconceptions such as objects stopping when no force is applied, which contradicts Newtonian and Einsteinian principles. Overcoming these hurdles requires a piecemeal acquisition of correct understanding, where students mix correct and naive reasoning.
Expert vs. Novice Reasoning in Physics Problem-Solving
Expert physicists and novice learners approach physics problems differently, showcasing distinctions in reasoning patterns. Experts focus on fundamental principles, while novices tend to get caught up in surface features of problems. Experts adopt a forward reasoning approach, starting from given information to apply relevant formulas, whereas novices work backward from the desired goal. This more demanding novice strategy often leads to rushed calculations, contrasting with the deeper understanding and problem analysis that experts prioritize.
