IMPLEMENTATION OF RECIPROCAL TEACHING LEARNING MODEL TO IMPROVE STUDENTS’ MATHEMATICAL REPRESENTATION ABILITY IN GRADE VII AT SMP NEGERI 37 MEDAN

This study aims to measure the increase in mathematical representation ability and classical completeness of VII grade students of SMP Negeri 37 Medan through the Reciprocal Teaching learning model on data presentation material. This research is a Classroom Action Research (CAR) conducted
in three cycles. The subjects in this study were students of class VII-B SMP Negeri 37 Medan T.A 2022/2023, totaling 32 students. The research results obtained in the initial test before the Reciprocal Teaching model was applied, classically, there were seven students (21.8%) completed with an average score of 54.68 in the deficient category. In cycle I, there was an increase in classically obtained as many as 20 students (62.5%) completed with an average score of 71.09 in the medium category. In cycle II, increased again classically as many as 24 students (75%) were complete with an average score of 79.37. Then, in cycle III, increased classically as many as 28 students (87.5%) completed with an average score of 82.18 in the high category. The ability of seventh-grade students at SMP Negeri 37 Medan to accurately represent mathematical concepts can be enhanced by implementing the Reciprocal Teaching learning model.
