Efektivitas Penerapan Model Contextual Teaching and Learning terhadap Pemahaman Konsep Matematis pada Materi SPLDV

Abstract

This research is motivated by the low understanding of students concepts in the SPLDV material. Therefore, to overcome this problem, a research was conducted using the Contextual Teaching and Learning (CTL) model. This study uses a true experimental design method with a pretest posttest control group design. The population in this study consisted of class VIII A, VIII B, and VIII C at MTS Hidayatul Mustafidin. Sample selection using cluster random sampling technique obtained class VIII B as the experimentak class and VIII C as the control class. The results of the implementation of experimental class learning showed an increase in understanding of mathematical concepts. The normalized gain test shows an increase in the value of the experimental class by 0,48 with a moderate interpretation, and the control class by 0,13 with a low interpretation. This study indicates that the Contextual Teaching and Learning model can be used as an alternative learning model to develop an understanding of mathematical concepts in the material for the SPLDV.
