Abstract: This study aims to determine the effect of 'Contextual Teaching and Learning' on students 'mathematical communication skills in terms of students' self-confidence. This research uses factorial design. The population in this study were all students of class VII Madrasah Tsanawiyah Ansharullah Birandang Island in the academic year 2018/2019. The sample of this study is students of class VII.B as an experimental class and class VIII as a control class. The instrument used was a questionnaire instrument to measure the level of students 'Self Confidence and description tests to measure students' mathematical communication skills. Data were analyzed using two-way ANOVA. Based on the results of data analysis, it can be concluded that: 1) There are differences in mathematical communication skills between students who take the CTL learning model and students who take conventional learning. 2) There is no influence of the interaction between CTL learning models with Self Confidence on students' mathematical communication skills. Thus in general the CTL learning model influences students' mathematical communication skills.Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh 'Contextual Teaching and Learning' terhadap kemampuan komunikasi matematis siswa ditinjau dari self-confidence siswa.

Students' mathematical communication is stated to be low because students learn by listening and seeing the teacher solve mathematical problems and students have difficulty in expressing everyday events in mathematical models. This study aims to determine whether there is an influence of the Inside Outside Circle (IOC) type of cooperative learning model on students' mathematical communication skills better than using scientific learning. This study uses a quantitative approach with the type of research Quasi-Experimental Design and the design of this research The Nonequivalent Postets-Only Control Group Design. The population in this study were all students of class VIII SMP Negeri 1 Nisam, while the samples were class VIIIB as the experimental class and class VIII-A as the control class with the sampling technique of purposive sampling. The data collection technique in this study used a mathematical communication ability test. The data analysis was carried out for the mathematical communication ability test using the t-test because the data were normally distributed and homogeneous, the data were processed using SPSS 18 software and the hypothesis test results were obtained with a significant value of 0.000 less than 0.05, which means reject H0 and accept Ha. The results showed that there was an effect of the Inside-Outside Circle (IOC) type of cooperative learning model on students' mathematical communication skills.

This research aims to determine whether or not there is an effect of the TTW cooperative learning model on the mathematics learning achievement of class VIII students of SMPN 2 Batukiang Utara in the 2020/2021 academic year. This type of research is a quasi experiment with the posttest only control design with nonequivalent groups. The subjects in this study were class VIII A as the experimental class using the TTW learning model and VIII B as the Kontron class with the direct learning model. The data collection technique used a research instrument in the form of a description test. The statistical analysis used in this study is the t test and the effect size test. Based on the data analysis, the results of the posttest showed that the experimental class average was 62.28 and the control class was 51.25. This indicates that learning with the TTW cooperative model is better than direct learning. Data analysis with t-test at a significant level of 5% , namely 4.03≥1.67, and the effect size test with d = 1.17 (high). So it can be concluded that the type of cooperative learning model (TTW) affects the mathematics learning achievement of class VIII students of SMPN 2 Batukliang Utara in the 2020/2021 school year

This study aims to develop a digital module using Flip PDF Professional to facilitate students' mathematical communication skills through contextual problems. This research is Research & Development (R&D). The development model used is the ADDIE development model. The stages in the development model are analysis, design, development, implementation, and evaluation. The digital module was piloted to class VIII A MTs Al Ichsan students for the 2020/2021 academic year. The module was compiled to meet the valid, practical, and effective criteria. Based on the results of the study, it was obtained that (1) The digital module is declared “valid” with an average expert score of 88% with the “excellent” criteria. (2) The digital module is declared “practical” with an average score percentage of 90% with the “excellent” criteria. (3) The digital module is declared “effective” with an average score percentage of 88% with the “excellent” criteria. The analysis results of the effectiveness of the digital module to facilitate mathematical communication skills show that the average test results of students are more than the minimum completeness criteria.

This study aims to (1) find out the activities of teachers and students during the implementation of mathematics learning activities by applying Think Pair Share (TPS) learning model, (2) knowing the improvement of students' mathematical communication skills on geometry. Based on the results of observations made by researchers, the cooperative learning model of the Think Pair Share (TPS) type has been going well. Teacher activities and student activities are in a good category, this can be seen from the average score of teacher activity in the first cycle reached 20.75 (good), in the second cycle to 23.25 (good). While the average observation score of students in the first cycle reached 13.75 (enough), in the second cycle it increased to 19.5 (good). The results of the communication skills test in the first cycle were in the adequate category (55.56% of 36 students) and in the next cycle increased to a good category (72.22% of 36 students). From the results of the tests in the second cycle, the study was stopped because it had reached the expected criteria, namely the number of students in good category ≥ 70% of 36 students. Thus it can be concluded that the application of the cooperative learning model of the Think Pair Share (TPS) type can improve the mathematical communication skills of students in class X MIPA 1 of SMAN 7 Bengkulu City.Keywords : Think Pair Share Learning Model, Mathematical Communication Ability
