Pemahaman Konseptual Matematis (PKM)  memiliki peran penting karena dengan kemampuan ini siswa mudah dalam membangun hubungan untuk memahamai ide dan konsep baru. Kemampuan PKM ini dapat ditumbuh-kembangkan melalui pembelajaran di kelas. Untuk mencapai kecakapan tersebut, pembelajaran perlu memperhatikan keberagaman siswa karena pembelajaran yang mengakomodasi keberagaman menjadi lebih efektif, efesien, dan menarik. Keberagam tersebut dapat berupa Gender (G), Kemampuan Awal Matematika (KAM) dan Gaya Belajar Matematis (GBM) siswa. Salah satu pendekatan pembelajaran yang mengakomodir keberagaman ialah pembelajaran pendekatan Rigorous Mathematical Thinking (RMT). Artikel ini bertujuan untuk mengkaji kemampuan PKM siswa SMP yang memperoleh pembelajaran pendekatan RMT ditinjau dari : a). Gender, b). KAM siswa, dan c). GBM siswa. Penelitian ini merupakan penelitian eksperimen pada siswa SMP di salah satu sekolah di Bandung. Salah satu hasil yang penting adalah dengan pembelajaran ini menjadikan siswa dengan KAM sedang dan rendah dapat mencapai kemampuan yang baik. The Effect of Rigorous Mathematical Thinking (RMT) Learning Approach On Students’ Understanding of Mathematical Concepts AbstractAn understanding of mathematical concepts (PKM) has an important role because with this ability students are easy in building relationships to understand new ideas and concepts. The ability of PKM can be grown-developed through learning in the classroom. To achieve these skills, learning needs to pay attention to the diversity of students because learning that accommodates diversity becomes more effective, efficient, and engaging. Such diversity can be Gender (G), An initial mathematical ability (KAM) and students’ mathematics learning styles (GBM). One approach to learning that accommodates diversity is the Rigorous Mathematical Thinking (RMT) learning approach. This article aims to examine the ability of junior high school students who have learned RMT approach in terms of: a). Gender, b). students’ KAM, and c). students’ GBM. This research is an experimental research on junior high school students in one school in Bandung. One important result is that this learning engages students with medium and low of KAM able to achieve good abilities.

Before And After

Learning mathematics is not only aimed at developing mathematical cognitive abilities, but also for developing affective domains. One important aspect in the affective domain that is very influential and determines success in learning mathematics is the positive view of students on mathematics or in mathematics learning called mathematical disposition. A student who has a high disposition will be more persistent and resilient in facing mathematical problems that are more challenging and will be more responsible for their own learning and always develop good habits in mathematics. The problem posing approach which in the learning process requires students to ask questions and make their solutions is expected to be able to change students 'views of mathematics to be more positive, while also improving students' mathematical abilities. This study aims to examine the differences in the levels of mathematical disposition of junior high school students before and after learning through the problem posing approach. The type of research is experimental research with the design of one group pre-test post-test design. The population in this study were all VII grade students of Bandar Baru 1 Junior High School, with research samples of class VII2 students selected through random sampling techniques. The instrument used to obtain the research data was a mathematical disposition scale questionnaire sheet. The statistical test used to analyze data on differences in mathematical disposition of junior high school students before and after learning through the problem posing approach is paired t-test. The results showed that there were significant differences in the level of mathematical disposition of junior high school students before and after learning through the problem posing approach. This means that students' mathematical dispositions get better after they get a problem posing learning approach. Keywords: Mathematical Disposition, Problem Posing Approach

Learning approaches, such as tactical approach and technical approach, have been widely discussed for promoting physical activity in physical education learning. The application of a suitable learning approach becomes an important issue related to different fitness level of individual. The purpose of this study was to investigate the results of basketball skill learning by applying the learning approaches based on the physical fitness level of adolescent students. A 2 x 2 factorial design (ANOVA) was applied in this study. Forty junior high school male students were involved in this study. They were divided into 4 groups, including 2 high physical fitness groups and 2 low physical fitness groups by applying the tactical approach and technical approach. This study used the Indonesian Physical Fitness Test (TKJI) instrument for the junior high school level and basketball skill test instruments, including passing, shooting, and dribbling tests. The results showed that, overall, students who received the tactical approach were better than students who received the technical approach. In the high physical fitness student group, the tactical learning approach showed a significant impact compared to the technical approach. However, in the students with low physical fitness group, the technical approach had a better effect on the students' basketball skills. It concludes that the two learning approaches are proven to be able to improve the outcomes of basketball skill learning. For that reason, it is recommended to teach basketball skills using a tactical approach to students with good physical fitness. However, if students have low physical fitness, it is suggested that technical learning approaches is given.

Mathematics learning is associated with 21st-century skills such as communication, collaboration, critical thinking in problem-solving, creativity, and innovation. To help students obtain these skills, a learning project was developed through Pendidikan Matematika Realistik Indonesia (PMRI) approach by using fruit salad recipes and collaborative learning based on the Lesson Study for Learning Community (LSLC) system. The primary purpose of this study was to develop fruit salad recipes to assist junior high school students in solving problems using mean, social arithmetic, and data presentation. It employed design research type validation studies using photos, fruit salad products, and document reviews as data collection techniques. The research subjects were 27 students of grade 8 from a junior high school in Palembang. This study resulted in a learning trajectory consisting of two activities and post-test questions. In the first activity, the students can analyze and solve problems in planning fruit salad recipes with material averaging, social arithmetic, and data presentation. In the second activity, the students can make fruit salads and write recipes based on skills to make fruit salad products. The results of this study demonstrate that in project-based learning through PMRI with the context of fruit salad recipes and the LSLC system, students can learn collaboratively. The learning helps them solve problems by using average material, social arithmetic, and data presentation in developing fruit salad recipes.
