The Subject

The purpose of this study is to improve the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan through the STAD type cooperative learning model. This research is a Class Action Research (CAR). The subjects of this study were 40 students of grade VII-1 MTs Islamiyah Medan. The object in this study is to improve students' mathematical problem-solving abilities through the STAD Type Cooperative learning model on the subject of rectangular flat shapes. This research instrument uses tests of mathematical problem-solving abilities, observation, and interviews. Based on the preliminary results of the interviews conducted with the mathematics teacher, it was obtained that the mathematical problem-solving ability of students in class VII-1 MTs Islamiyah Medan was still not optimal. From the data obtained only 17.5% of students met the mathematical problem-solving ability criteria. This research was conducted in two cycles by providing treatment using STAD learning. Based on the results of data analysis students' mathematical problem-solving abilities in the first cycle obtained that 70% of students meet the criteria. But because it has not reached 85% completeness then continued with the second cycle. In the second cycle, 90% of students who met the criteria of mathematical problem-solving ability were obtained. The conclusion of this study is an increase in students' mathematical problem-solving abilities from cycle I to cycle II.

Before And After

This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test. The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.
