Program Resitasi Berbasis Multi Representasi Disertai Umpan Balik dan Soal Penguatan Untuk Meningkatkan Penguasaan Konsep Momentum dan Impuls

This study aims to identify the improvement of students' conceptual mastery through a multi-representation-based recitation program accompanied by feedback and reinforcement questions. The method used in this study is a mixed method with an Embedded Experimental Model research design carried out on 84 students of the Physics Undergraduate Program, the State University of Malang, who took the Basic Physics course in the 2020/2021 academic year. The results showed that the mastery of the concepts of momentum and impulse students increased, marked by the transition of students' answers to questions with the context of determining impulses in related problems and determining the conservation of momentum in associated issues and the average of students from 30.8 to 52.8.
