This study aims to determine the influence of the cooperative learning model CORE type on the mathematical communication skills at the eight grade students of SMPN 2 Kediri in Academic Year 2019/2020 on cube and block material. The method used in this study was a quasi-experimental research design with post-test only control group design. The population of this study were all eight grade students of SMPN 2 Kediri in academic year 2019/2020, which were distributed in three classes. The sample class was selected using cluster random sampling technique, obtained class VIII-B as the experimental class and class VIII-C as the control class. As for data collection techniques, namely observation and tests. The data analysis technique used the prerequisite test, namely the normality test and the homogeneity test followed by the pooled variance t-test. Based on the results of data analysis, it was found that there was a difference between the mathematical communication skills of students who obtained the cooperative learning model CORE type and those who used the direct learning model. Classes that using the CORE model get an average score of 77.86 while those taught with the direct learning model get an average score of 65.15. This shows that learning using the cooperative model type CORE has an influence on the mathematical communication skills of students of class VIII SMPN 2 Kediri in academic year.

This research was motivated by the lack of learning tools that can improve students' Mathematical Communication Skills (KKM). Activities that can encourage students to improve KKM have not been designed by the teacher in the learning device properly. This study aims to produce learning tools by applying Problem Based Learning models to improve KKM. This development research used the ADDIE development model with the stages of Analysis, Design, Development, Implementation, and Evaluation. The results of Syllabus, RPP, LKPD and KKM validation results showed highly valid criteria with percentages of 91.67%, 91.30%, 89.09%, and 87.15%, respectively. Practicality results indicate a very practical criterion with the percentage of small group trials at 95.57%, large group trials at 96.07%, and teacher responses at 96.25%. The effectiveness test results state that KKM of students who use learning tools with PBL models is better than KKM of students who use conventional learning.

Mathematical communication skills are one of the abilities that students must have to make it easier to solve problems contained in mathematics itself and in everyday life. Because if students have mastered mathematical communication skills, it will make it easier for students to take deeper learning. This study aims to analyze the difficulty of students' mathematical communication skills using the Google Classroom Application in the Algebra course. This type of research is descriptive qualitative. The subjects of this study were tree semester students who took Algebra courses in the Mathematics Education study program at Universitas Muhammadiyah Tapanuli Selatan, academic year 2020/2021 as many as 15 people. The instrument used in this study was Test and interview. The results showed that based on the test results obtained: difficulties in the ability to interpret mathematical ideas rationally in writing, difficulties in mathematical problems into mathematical models and difficulties in the ability to express mathematical ideas in the form of descriptions. Meanwhile, based on the results of the interview, namely: (1) technical difficulties, and (2) student adaptation difficulties. To overcome these difficulties, it is necessary which is a combination of Online and Offline learning or also called blended learning.

This study aims to test the validity, practicality, and effectiveness of pop-up questions-based learning videos integrated with religious characters of the human digestive system. The subjects of this study were students of class VIII A and VIII C of MTs Mazro'illah, Lubuklinggau City. This research is a type of research and development (R&D) that uses the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The data collection instruments in this study consisted of interview guides, expert validation questionnaires, practicality questionnaires, and test sheets. The results of the research data analysis showed that the experts stated that the three learning videos developed were very valid with an average score of 89.70% for the first video, 91.40% for the second video, and 90.80% for the third video. The learning videos that have been declared valid are then tested on students to find out the practicality of the learning videos developed. The results of the practicality questionnaire showed good responses by students and teachers with an average score of 85 and 84, respectively. The learning videos developed were then implemented for students to determine the effectiveness in aspects of knowledge and attitudes. The test results show that the ability of the students' knowledge aspect is still in the poor category with an average score of 55.20%, while the attitude aspect of students shows different things with an average score of 92.50% which is included in the very good criteria. Based on the results of this study, the pop-up question-based learning video integrated with the religious character of the human digestive system material was declared to be very valid, practical, and effective in the aspect of religious attitudes to be used in learning

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.
