Abstract

This study aims to determine whether there is an effect of the Contextual Teaching and Learning model on learning outcomes and student learning activities at SMP Negeri 9 Pematangsiantar. The method used in this research is an experimental method using a True Experimental Design in the form of Pretest-Posttest Control Design. The sample consisted of two classes, namely the experimental class which was treated with the Contextual Teaching and Learning learning model and the control class which was given the conventional learning model, each of which amounted to 32 people. The data were collected by the method of tests and questionnaires. The number of test items used were 5 essay questions and 20 questionnaire items that had been declared eligible. Data analysis used normality test, homogeneity test, and hypothesis testing. The results of hypothesis testing showed that there was an effect of the Contextual Teaching and Learning learning model on learning outcomes and student learning activities at SMP Negeri 9 Pematangsiantar.

Abstract

The purpose of this study was to determine whether the use of the 3D Cabri application had an impact on student learning outcomes in studying prisms of building materials or not. This research is quantitative research with experimental research methods and True Experimental Design in the form of a Pretest-Postest Control Design. This research was conducted at SMP Negeri 1 Jorlang Hataran. The samples used in this study were students of classes VIII-4 and VIII-8, each of which amounted to 32 people. The instrument used is an essay test with 5 items that have been tested for feasibility. Data collection techniques in research are through observation, tests, and documentation. The data analysis technique is using Liliefors test for the normality test, Fisher's test for the homogeneity test, and a t-test for hypothesis testing. After the two sample data are declared normal and homogeneous, it can be continued with hypothesis testing. From the results of data analysis, it was found that the use of Cabri 3D had an effect on student learning outcomes in the material of building prisms at SMP Negeri 1 Jorlang Hataran.

Abstract

This study aims to determine whether there is an effect of the Contextual Teaching and Learning model on the mathematical reasoning abilities of seventh-grade students at SMP Negeri 9 Pematangsiantar. The method used in this research is an experimental method using a True Experimental Design in the form of a Pretest-Posttest Control Design. The sample consisted of two classes, namely the experimental class which was treated with the Contextual Teaching and Learning learning model, and the control class which was given the conventional learning model, each sample group totaling 32 people. Data were collected by observation, test, and documentation methods. Analysis of the data used is using normality test, homogeneity test, and hypothesis testing. The results of hypothesis testing indicate that there is an effect of the Contextual Teaching and Learning learning model on the mathematical reasoning abilities of seventh-grade students at SMP Negeri 9 Pematangsiantar.

Abstract

The purpose of this study was to determine the effect of the use of the learning model, the effect of the Think Pair Share (TPS) cooperative learning model on the mathematical communication skills of students in class VIII of SMP Negeri 12 Pematangsiantar. The design of this study used a pretest-posttest only control group design. The population in this study were all students of class VIII SMP Negeri 12 Pematangsiantar T.A 2022/2023, and the sample in this study were all students of class VIII-6 SMP Negeri 12 Pematangsiantar T.A 2022/2023 totaling 30 students. The instruments used in this study are validity, reliability, level of difficulty of test items and distinguishing power of test items. The data obtained were then analyzed using data analysis techniques, the average value of the Think Pair Share (TPS) learning model was 82.13 and the average mathematical communication ability was 56.03. The results of hypothesis testing after obtained thitung = 11.052 and ttable = 2.045. This means that thitung > from ttable which indicates the null hypothesis is rejected. Based on the description, it is concluded that the use of the Think Pair Share (TPS) learning model has an influence on students' mathematical communication skills in learning functions in class VIII of SMP Negeri 12 Pematangsiantar

Abstract

Mathematical reasoning ability is one of the learning objectives that are expected to develop optimally in students. But in reality, students' mathematical reasoning abilities cannot always be achieved by students optimally. This is also found in class VIII SMP Negeri 3 Pematangsiantar. One of the factors that causes this to happen is the lack of trained students to use and develop mathematical reasoning skills properly. One of the efforts that can be done to improve students' mathematical reasoning abilities is to apply a contextual teaching and learning approach. The purpose of this study was to determine whether the mathematical reasoning ability of students who used a contextual teaching and learning approach was better than the mathematical reasoning abilities of students who used conventional learning in class VIII of SMP Negeri 3 Pematangsiantar. The type of research used was a quasi-experimental design with a posttest only control design. design. The population in this study were eighth grade students of SMP Negeri 3 Pematangsiantar. Sampling was done by random sampling technique. Class VIII-7 was selected as the experimental class and class VIII-8 as the control class. The research instrument used was a final test sheet in the form of description questions to see students' mathematical reasoning abilities. Based on the analysis of the results of the final test of students' mathematical reasoning abilities, it was concluded that mathematical reasoning abilities by learning using a contextual teaching and learning approach were better than learning using conventional learning, which could be seen at an error rate of 5%. This shows that there is an influence on students' mathematical reasoning abilities. The average test for the experimental class is 82.63 and the control class is 60.59
