This study aims to determine the ability to solve math story problems for class VIII students of SMPN 23 Simbang by using the Cooperative Reading Comprehension and Composition (CIRC) cooperative learning model. This type of research is an experiment using a quantitative approach. The design in this study uses True Experimental Design in the Posttest-Only Control Design category. The sampling technique used is simple random sampling. In this study the sample chosen was class VIIIA as the experimental class (using the CIRC cooperative learning model) and class VIIIB as the control class (using conventional learning models in learning). The data collection used includes observation sheets and tests of student learning outcomes that have been validated by experts. The data in this study used prerequisite analysis and hypothesis testing, namely the independent t-test. Based on the analysis of hypothesis testing, it shows that the ability to solve math story problems for class VIII students of SMPN 23 Simbang by using the Cooperative Reading Comprehension and Composition (CIRC) cooperative learning model is better than the conventional learning model.
