ABSTRACT
Physics instruction looks different from one classroom to the next; however, the outcome of those classrooms should be one and the same. Students should understand simple concepts and be able to transfer concepts to more complex problems. This chapter provides students with an opportunity to explore their ideas before formulae or calculations are introduced. Students explain that the normal force becomes increasingly opposite to the direction of the force of gravity as the angle of the ramp decreases. The model lesson is an effective approach to teaching forces relating to the movement of an object rolling down an inclined plane. It creates an opportunity for students to understand the concept because it emphasizes a conceptual approach, providing students with hands-on experiences and guiding student inquiry prior to "solving the problem." When students understand the concept, they not only can solve the problem; they can transfer what they know to unique situations.
