Abstrak Kurangnya variasi pembelajaran yang diberikan pada suatu kelas menjadi salah satu penyebab rendahnya kemampuan pemecahan masalah matematik dan productive disposition siswa SD. Untuk meningkatkan kemampuan tersebut diterpkan pembelajaran menggunakan pendekatan problem solving berbantuan microsoft mathematics pada materi pecahan kelas VI SD Negeri di kota Bandung dengan sampel sebanyak 2 kelas yang diteliti secara kuasi eksperimen. Tes kemampuan pemecahan masalah matematik dan nontes skala sikap productive disposition menjadi instrumen dalam penelitian ini. Dapat digeneralisir temuan dalam penelitian ini yakni pencapaian dan peningkatan kemampuan pemecahan masalah matematik dan productive disposition siswa yang pembelajaran menggunakan pendekatan problem solving berbantuan microsoft mathematics lebih baik secara signifikan dari siswa yang menerima pembelajaran secara biasa serta terdapat asosiasi yang signifikan antara kemampuan pemecahan masalah matematik dan productive disposition pada siswa yang menemrima pembelajaran menggunakan pendekatan problem solving berbantuan microsoft mathematics. Pembelajaran menjadi lebih variatif dengan fitur pada aplikasi sehingga siswa lebih antusias dan bermakna dalam belajar matematika pada siswa SD. Abstract The lack of variety in learning given to a class is one of the causes of the low of mathematical problem solving ability and the productive disposition of elementary school students. To improve this ability, learning using a problem solving approach assisted by microsoft mathematics is applied to the fractions material of 6th grade at elementary schools in Bandung city with a sample of 2 classes carried out in a quasi-experimental research. The mathematical problem-solving ability test and the non-test of the productive disposition attitude scale became the instruments in this study. It can be generalized the findings in this study, namely building and improving mathematical problem solving skills and productive dispositions of students who learn using a Microsoft mathematics-assisted problem solving approach significantly better than students who receive ordinary learning and there is a significant association between problem solving abilities and productive disposition in students who receive learning using a problem solving approach assisted by microsoft math. Learning becomes more varied with the features in the application so that students are more enthusiastic and meaningful in learning mathematics for elementary students.

The purpose of this research was to identify students' difficulties in answering questions about mathematical problem solving abilities (KPMM) on the material quadratic equation (PK). The method used in this research is qualitative descriptive method. The subjects in this research were 18 students of class IX at SMPN 1 Cihampelas. The data collection technique was using a test question the KPMM with of 4 grains question. The results of this research found the level of students' ability to answer KPMM-PK questions based on the KPMM steps. The highest percentage of 74% lies in the difficulty of checking the correctness of answers with difficult criteria. While the lowest percentage of 60% lies in the difficulty of planning a settlement with quite difficult criteria. Meanwhile, when viewed from the level of student ability, the difficulties of students with high abilities have not difficult criteria, the difficulties of students who have moderate abilities are in the slightly difficult criteria, and the difficulties of students who have low abilities lie in quite difficult criteria.

Students' understanding of linear equations with one variable is still low. Of the total number of students in the class, namely 32 students, only 10 students scored above the minimum completeness criteria (KKM) while the remaining 22 scored below the KKM. This research aims to determine the improvement of mathematical communication skills by using problem-based learning better than ordinary learning. Two classes, an experimental group, and a control group, were selected for this study. The researchers tested the technique because experimental research requires both groups to have the same skill level. The researcher used a test of students' mathematical communication skills as a research tool in this study. The average N-gain score for students who apply the problem-based learning model with regular learning is 0.71 (high category), higher than students who receive regular learning. of 0.10 (low category). Then the N-gain score normality test was carried out, the results obtained were 0.023 in the experimental class and 0.216 in the control class and the results obtained were not normally distributed. Then proceed with non-parametric tests, from the results of the Mann-Whitney U-Test obtained by Asymp. Sig (1-tailed) is 0.000 ˂ which indicates it is rejected, meaning that the increase in mathematical communication skills of experimental class students is significantly better than that of the control class. The PBL model improves students' mathematical communication by promoting critical thinking, collaborative work, and active problem-solving. It also allows students to understand the practical relevance of mathematical concepts in real-life situations.

Adaptation in implementation and learning is the key to creating competent, excellent, and globally competitive human resources. Differentiated learning can address this challenge as it aligns with students' conditions, needs, and potential. This approach can stimulate students to master Mathematical Reversible Thinking Ability (KRTM), which plays a crucial role in students' success in solving mathematical problems. Despite its significance, field observations indicate that this ability remains relatively low. As a solution, a VBA-Excel-based digital module can be utilized in differentiated learning as a strategy to effectively enhance KRTM. he aim of this research is to assess the effectiveness of implementing differentiated learning using a VBA-Excel-based digital module to improve high school students' KRTM. The research method employed is the Mixed Method with The Explanatory Sequential Design. The research was carried out with high school students in a district in Bandung. The research instruments included ability tests and open-ended questionnaires to collect students' responses. The findings indicate that the differentiated learning strategy using a VBA-Excel-based digital module significantly improves KRTM. Students demonstrated a good understanding of the material and showed enthusiasm in learning, as the approach aligns with their characteristics and needs.

This research aims to stimulate mathematical communication skills in statistics for junior high school students using a realistic mathematics education approach to support the Pancasila student profile. In this research, the researcher chose a quasi-experimental research method. The population in this study were all class VIII students in one of the junior high schools in the city of Bandung, and two classes were used as research samples selected by purposive sampling. The first class was made into an experimental class using the RME approach. The second class was used as a control class whose learning used ordinary learning. The results of this study show that 1) There is a positive correlation between the Pancasila student profile and mathematical communication skills in experimental class students, this is because the mutual cooperation dimension in P5 emphasizes communication skills. 2) students' mathematical communication skills increase from the low category to the high category. 3) the students' characters are more similar to Pancasila students after being taught mathematics with a realistic approach.
