Abstract

The purpose of this research is to find out how the influence of the Team Assisted Individualization (TAI) type cooperative learning model on students' mathematics learning outcomes in class VII algebra form material at UPTD SMP Negeri12 Pematang Siantar. The approach taken in this study is a quantitative approach. The instruments used in this study were questionnaires (questionnaires) and learning outcome tests. Data analysis techniques use prerequisite tests, namely normality tests and linearity tests. To test whether Team Assisted Individualization (TAI) type cooperative learning models affect learning outcomes, a simple linear regression test was used. From the simple linear regression test performed, the regression equation Y = 8.804 + 0175.X which can be interpreted as every addition of 1% of the questionnaire value will cause an increase in learning outcome test scores of 0.175. It can be seen that the value of the regression coefficient is greater than 0 (positive value), so there is a positive influence between variable 50,8%.

Abstract

The aim of this research aims to see the influence of the Think Pair Share Type Cooperative Learning Model on Students' Ability to Understand Mathematical Concepts in Algebra Form Class VII UPTD SMP Negeri 3 Pematang Siantar. The type of research used in this research is quantitative research, because the data and research are in the form of numbers and require statistical calculations. In this research, the design used is a Pre-Experimental Design in the form of a One Shot Case Study. In this design, there is treatment given to the experimental class, namely the application of the Think Pair Share type cooperative learning model. This research was carried out in class VII UPTD of SMP Negeri 3 Pematang Siantar which is located on Jl. Laguboti Ujung, Martimbang Village, District. South Siantar, Pematang Siantar City. In this research, the sampling technique used is probability sampling with simple random sampling type. Based on the results of the research and discussion previously presented, it can be concluded that there is a positive and significant influence of the Think Pair Share type cooperative learning model on the ability to understand mathematical concepts of class VII students at UPTD SMP Negeri 3 Pematang Siantar Q.A 2023/2024. This influence can be seen through the regression equation Y = 11.572 + 0.140 H1 is accepted and the magnitude of the influence on the coefficient of determination is 23.2%.

Abstract

This research aims to describe and analyze the mathematical problem solving abilities of class VIII students at SMP Negeri 5 Pematangsiantar on two-variable linear equation systems material, with treatment in the form of a Contextual Teaching And Learning (CTL) learning model. The approach taken in this research is a quantitative approach. Sampling was carried out using a simple random sampling technique. The research subjects were class VIII-6, totaling 30 people. The data collection technique in this research is in the form of a test to determine students' mathematical problem solving abilities in the research process carried out. Data analysis techniques were carried out using normality tests and hypothesis tests. From the results of data analysis, the results of students' mathematical problem solving abilities showed that the average pre-test score was 54336 and the average post-test score = 79,400. A significant value (2-tailed) 0.000 < 0.05 indicates that there is a significant difference between the initial and final variables. Thus, the independent variable has a significant effect on the dependent variable. So it can be concluded that by applying the Contextual Teaching And Learning CTL learning model) it can improve the mathematical problem solving abilities of class VIII students at SMP Negeri 5 Pematangsiantar on the material of two-variable linear equation systems.
