Achieving knowledge integration for deep learning requires students to develop well-connected knowledge structures through the central idea of a concept. However, a number of studies on student learning in momentum have revealed persistent difficulties in understanding its fundamental concept, particularly in relating net force, time, and change in momentum with each other. This study evaluates the effectiveness of a teaching intervention based on the conceptual framework of momentum that targets knowledge integration. The evaluation outcomes of the intervention provide encouraging evidence suggesting that the conceptual framework model can be a valuable guide to the development of instruction for promoting knowledge integration and deep learning.
