Abstract

The purpose of this study was to determine the differences in mathematical reasoning ability (KPM) based on gender variation (VG) and mathematical self-efficacy (SEM). Quantitative research was chosen to answer the research question. The research design used comparative causality on 75 students at a State University in Mataram City. Data collection was based on gender variance in the selected sample (51 women and 24 men, KPM test scores consisting of 5 items, and a 20-point SEM questionnaire, which were further categorized into 3 levels (low, medium and high). Analysis The data used two-way ANOVA with a 3 x 2 factorial design. The post-anava follow-up test used the turkey test. The results showed that male KPM was better than female KPM. Based on SEM category, student KPM at high SEM was better than student KPM at low SEM This finding emphasizes the importance of instructors being able to observe the characteristics of self-efficacy and gender variations that have an impact on the mathematics learning process.

Abstract

Self-confidence is one of the affective aspects that must be considered and developed, especially in building student readiness in undergoing online learning in the current pandemic era. This study aims to analyze the confidence of mathematics education students in online learning in the era of the covid-19 pandemic. This research use descriptive qualitative approach. The subjects of this study were first semester students who took the Differential Calculus course in the Mathematics Education study program at the Universitas Muhammadiyah Tapanuli Selatan for the 2021/2022 academic year. The instrument used in this research is a questionnaire. The data obtained in this study were analyzed descriptively. Based on the results of the study, it shows that the indicators of student self-confidence in online learning in the era of the covid-19 pandemic have not fully achieved, but most of the indicators have mostly achieved self-confidence, namely the first indicator of believing in self-ability, most of them have achieved self-confidence. Students also have not fully met the second indicator, namely being able to act independently in making decisions. In the third indicator having a positive self-concept, most students have achieved this indicator. In the fourth indicator, namely daring to express opinions, almost some students have the courage to express opinions. To further increase student confidence, it is necessary to provide innovation in the implementation of online learning.

Abstract

The purpose of this research to describe the level validity of mathematics lesson plan by using the Contextual Teaching and Learning (CTL) Approach on Quadrangle Substance at Grade VII MTs Negeri 3 Siak which was valid test. The development model in this research used an R&D model with six stages were the researcher have modified depends on the needs and conditions with current situation now it’s covid-19 pandemic. These six stages arepotential and problems, data collection, product design, design validation, design revision and final product. The data collection technique used in this research was the validation of lesson plan, the kind of data collection instrument was the form of a validation sheet. While the data analysis technique used in the form of descriptive analysis by describing the validity of the lesson plan which was developed by the researcher. The results of this research, the RPP validation were 85.86% with very valid criteria. While the results of LKPD validation were 89.81% with very valid criteria. Based on the results of this research, it can be concluded that the development of mathematics lesson plan with a Contextual Teaching and Learning (CTL) approach on quadrangle substance at grade VII MTs Negeri 3 Siak has been suitable for the validity.

Abstract

This research aimed to produce questions of mathematical literacy ability of Mathematical literacy ability on Triangular material for Class VII Junior High School students that are valid and practical and have a good level of difficulty and discriminatory index. This research used the Tessmer development model. Tessmer's development stages include preliminary, self-evaluation, expert review, one-to-one, and small group. The test subjects of this study were class VII students of SMP Negeri 02 Kepahiang, totaling 30 students. The selection of test subjects includes high, medium and low abilities. The data analysis technique of this study used qualitative analysis at the expert review and one to one stage and quantitative analysis at the small group stage by analyzing items based on the level of difficulty and discriminating power index. The results of the research show that the 10 questions developed, 10 questions with indicators of mathematical literacy ability on triangular material are valid and practical, 7 questions are said to be good based on the level of difficulty and discriminatory index, so that they can be used by all students of SMPN 02 Kepahiang.

Abstract

This study aims to describe the ability to understand mathematical concepts, activities and student responses in learning mathematics with realistic mathematics education approach. To achieve this goal, a quasi-experimental study was conducted with one group pretest posttest design. The population of the study was the eighth grade students of SMP Negeri 4 Angkola Timur, sampling by purposive sampling, namely class 8-2, totaling 26 students. Research activities include the stages of giving the Pre-test followed by learning for 3 meetings which then ends with a final test. Through research conducted using the Paired Samples Test, a significance of 0.00 < 0.05 was obtained, which gave the decision that the initial hypothesis was accepted. Of the 9 aspects of learning activities studied in the application of realistic mathematics education, the overall average value of the percentage of all activities met the active criteria. Furthermore, the average overall student response to being happy, new, interested and understanding/interested in the implementation of realistic mathematics education is 91.11% ≥ 85%. Thus it is concluded that: 1) The implementation of a realistic mathematics education approach has a significant positive influence in learning students' ability to understand mathematical concepts; 2) Student activities in learning mathematics with realistic mathematics education approach are effective; 3) Student responses to learning activities with realistic mathematics education are in the positive category.
