Efektivitas Model Pembelajaran Contextual Teaching and Learning terhadap Kemampuan Pemecahan Masalah Matematis Siswa

Abstract

This research aims to determine the effectiveness of the contextual teaching and learning model on students' mathematical problem-solving abilities. This type of research is quasi experimental research with a pre-test post-test control group design. The population in this study were all class VIII students at the Wustho An-Ni'mah Batam Salafiyah Islamic Boarding School. The subjects in this research were 22 students from class VIII A as the experimental class and 12 students from class VIII B as the control class. The sampling technique was carried out using a saturated sample technique. Data was obtained with a test instrument consisting of 4 questions which had been tested for validity and reliability (rii = 0.67). The data analysis techniques used are normality tests, homogeneity tests, and hypothesis tests which include paired sample t-test and independent sample t-test. Based on the results of data analysis, (1) The CTL learning model is effective on students' mathematical problem-solving abilities, (2) The Direct Instruction learning model is not effective for students' mathematical problem-solving abilities, (3) There are differences in the effectiveness of the CTL learning model and the Direct Instruction learning model on students' mathematical problem solving abilities.
