Abstract
The purpose of this study is (1) to determine the effect of the learning model (CTL) on the mathematics problem-solving abilities of the fifth-grade students of SDN 11 KK. (2) to determine the application of the learning model (CTL) in class V SDN 11 KK. The method used is ex post facto with a causal research design. The number of samples was 48 students divided into two groups, the experimental group used the CTL model and the control group used conventional methods. The research instrument used an essay test with 4 indicators of the test. The test is a pre-test & a final test of students' mathematical problem-solving abilities. Data processing techniques used statistical processing t-test & Wilcoxon test because one of the data is not normally distributed. Based on the results of the pretest and posttest data analysis for the experimental class can be concluded that there is no significant initial ability between the experimental class and the control class. Based on the results of the posttest data analysis of the experimental class and the posttest control class, it can be concluded that there is an effect of the CTL learning model on the mathematics problem-solving abilities of the fifth-grade students of SDN 11 KK.
