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 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 research aimed to determine the effect of the Realistic Mathematics Education (RME) learning model on students critical thinking ability for systems of linear equations with two variabels material in class VIII at SMP Negeri 3 Jerowaru for the academic year 2023/2024. Research with a quantitative approach that uses a quasi-experimental design, the experimental class learning using the RME learning model while the control class using direct learning. The population in this study was 3 class VIII students. The samples were taken using a simple random sampling technique, resulting in class VIII A as the experimental class and VIII B as the control class. Data collection was carried out using critical thinking ability test questions (posttest). From the research results, it was found that there were differences between the experimental class and the control class. Judging from the average score of the experimental class 69.08 and the control class 58.40, this shows that the critical thinking ability of the class whose learning uses RME is better than the class whose learning uses direct learning. The effect size test results obtained were 0.69, which is in the medium category. So it can be concluded that there is an effect of the RME learning model on students' critical thinking skills in SPLDV material in class VIII of SMP Negeri 3 Jerowaru in the medium category.

Abstract

Reasoning ability is a high-level thinking ability in learning mathematics. Mathematical reasoning and mathematics learning are two things that are interrelated and cannot be separated because mathematical material is understood through reasoning, and reasoning can be trained through studying mathematics. To achieve mathematical reasoning abilities in learning, students need adequate behavior, one of which is learning independence. The aim of this research is to analyze mathematical reasoning abilities based on students' independent learning at SMPN 1 Praya Timur on straight line equations. The method used in this research is qualitative research with descriptive methods. The samples in this study were taken randomly based on the class in the population. The class that the researcher took as a sample in this study was class VIII C at SMPN 1 Praya Timur for the 2023–2024 academic year. The results of this study show that subjects with low reasoning abilities are also categorized as having low learning independence. The learning ability of students who are categorized as moderate turns out to be moderate. So, it can be concluded that the relationship between learning independence and reasoning ability is based on high student learning independence, so their reasoning ability is also high. Based on the results of this research, it is hoped that teachers can develop teaching and practice problem-solving questions to improve students' reasoning abilities
