Conceptual Change Capability of the pra concepts constructed by students from the experience gained, most of which are not in accordance with scientific concepts. From the 5 items regarding concepts about movement, it can be seen that the students' pretest results (pre-concept abilities) are still very low. To carry out the process of changing students' preconcepts, it is necessary to use an approach or learning model that involves the process of Assimilation and Accommodation in the learning process, because changing students' pra concepts requires a cognitive conflict that is able to convince students that their initial knowledge (pra concepts) has been constructed into knowledge. science can be replaced with correct and appropriate concepts.
