Abstract

This research aims to determine the effect of the cooperative learning model typeTwo Stay Two Stray (MP-TSTS) on the mathematics learning outcomes of class VIII students at MTs Al Aziziyah Putra Gunungsari. The type of research used is quantitative descriptive researchPost-test Only Control Design. The population in this study were all class VIII students at MTs Al Aziziyah Putra Gunungsari, consisting of 8 classes. The sample in this research was students in classes VIII A and VIII B. The instrument used in this research was a learning outcomes test. The data collected consists of student learning outcomes data. Data were analyzed using descriptive analysis. Results of inferential analysis using test independent sample t-test with the help ofSPSS 23 to test the hypothesis shows that the student learning outcomes data on post-test, gain normalized and student learning outcomes data with a significant value (2-tailed) < 0.05, namely 0.029. So the learning outcomes of students who use MP-TSTS and students who use the small group discussion method are significantly different. This means that MP-TSTS has an effect on improving learning outcomes. Based on the results of the inferential analysis, it can be concluded that the implementation of MP-TSTS is effective/influenced on the mathematics learning outcomes of class VIII students at MTs Al Aziziyah Putra Gunungsari for the 2022/2023 academic year.

Abstract

This study aims to perform modeling and determine the factors that significantly and not significantly influence the completion of the thesis. The analysis used is the path analysis of the decomposition method. The data used is primary data by distributing questionnaires. Based on the results of the analysis that has been done, the path analysis model for the factors that influence the completion of the thesis are: The factors that significantly effect are facilities (), selection of specialization courses (), and selection of courses (). While lecturer factor () and motivation factor () have no effect. Supporting facilities factor and selection of supporting courses factor only directly affect the completion of minithesis. While the selection of specialization courses also has indirect effect to the completionof the thesis.

Abstract

This research aims to determine the level and describe critical thinking abilities in solving story problems on fractional numbers in terms of the personality types of class VII students at SMPN 17 Mataram. This type of research is using mix method. The instrument used is a personality type test, namely a standardized personality testMyers Briggs Type Indicator (MBTI), critical thinking ability tests, and interview guidelines. The sample for this research was class VII-A students, totaling 32 students. From this class, 8 subjects were taken, namely high, medium and low categories for each personality type extrovert, introvert, andambivert to conduct in-depth interviews. The results of the research show that the percentage of students' critical thinking abilities has personality extrovert is 27.31%, namely in the low category. Percentage of students' critical thinking abilities with personality introvert is 57.54%, namely in the medium category. Percentage of students' critical thinking abilities with personality ambivert is 50.23%, namely in the medium category. The research results also show that students have personality extrovert with critical thinking skills in the medium category can go through the clarification and assessment stages while students with personality extrovert Low categories tend to only go through the clarification stage. Personality students introvert with high category critical thinking skills tend to go through the stages of clarification, assessment, strategy and conclusion. Then students have personality introvert Medium categories tend to go through the clarification and strategy stages. Meanwhile, students have personality introvert those in the low category tend to only go through the clarification stage. Personality students ambivert with high category critical thinking skills tend to go through the stages of clarification, assessment, strategy and conclusion. Then students have personality ambivert Medium categories tend to go through the clarification and strategy stages. Meanwhile, students have personality ambivert Low categories tend to only go through the clarification stage

Abstract

This qualitative descriptive research aims to describe students' mathematical problem solving abilities based on Polya indicators in solving social arithmetic problems in terms of self-efficacy. The research subjects were 4 students in class VII of SMP Negeri 4 Gunung Sari for the 2022/2023 academic year, consisting of 2 students in the high category and 2 students in the low category. Data collection techniques using questionnaires, tests and interviews. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results of this research were obtained from (i) students with level self-efficacy high have high mathematical problem solving abilities can go through all stages of problem solving abilities, namely understanding the problem, preparing a plan, implementing the plan, and checking again. (ii) students by level self-efficacy Low students have low mathematical problem solving abilities which can also be seen from the results of students' work through only two stages, namely the stage of understanding the problem and implementing the plan. With suggestions for students who are at each category level self-efficacy and the level of mathematical problem solving abilities, it is hoped that they can further maximize their abilities

Abstract

This study aims to develop Technological Pedagogical Content Knowledge (TPACK)-based learning media oriented towards motivation and mathematics learning outcomes that are valid, practical and effective. The subjects in this study are class VIII students at one of the junior high school in Mataram. This type of this study is Research and Development with the ADDIE (Analysis, Design, Development, Implementation and Evaluation) model. Data analysis in this study was carried out using descriptive quantitative and qualitative regarding the advisibility of learning media obtained from assessment or validation sheets, analysis of the practicality of learning media obtained from student response questionnaires and teacher responses to learning media, and analysis of the effectiveness of learning media obtained from posttest results. The study results obtained that:  TPACK-based learning media has been developed is suitable for use as learning media with high validity; TPACK-based learning media is practically used as learning media with a practicality score of 79.67%;  The N-gain value for increasing students matemathics learning motivation is 43.34% in the medium category, while for increasing students matemathics learning outcomes it is 56.74% in the medium category. Based on the results, TPACK-based learning media is suitable for use, practically applied for learning, less effective for increasing learning motivation, and quite effective in improving learning outcomes
