PENGARUH MODEL PEMBELAJARAN KONTEKSTUAL TERHADAP PEMAHAMAN KONSEP MATEMATIKA SISWA

Abstract

One of the problems in learning mathematics is that students' absorption and understanding of mathematical concepts is still low. One learning model that can be used to solve this problem is the contextual learning model. The aim of this research is to determine the effect of contextual learning models on students' understanding of mathematical concepts. This type of research uses a pretest- posttest control group design. The population used in this research were all class VII students at SMPI Scholar Daarul Mubtadien and the sample was chosen randomly so that a sample size of 40 students was obtained which was divided into experimental class and control class. Data collection techniques are carried out by observation and tests. The data obtained was then tested using validation, reliability, difficulty index and discrimination tests. The test results were then analyzed using the normality test, homogeneity test, simple linear regression analysis and t-test. Based on the results of data analysis, it can be concluded that the contextual learning model has a significant effect on students' understanding of mathematical concepts (0,09 >0,05), and there is a significant difference between the average statistical value of the control class and the experimental class (0,020< 0,05). Based on these conclusions, suggestions can be given that the contextual learning model should be used as a learning model to improve students' mathematics learning outcomes in other materials.
