Students' mathematical reasoning skills are very important in understanding mathematical concepts and solving mathematical problems. The lack of students' reasoning ability can affect student learning outcomes that do not reach the target so it needs to be honed in order to realize appropriate learning outcomes. The purpose of this research is to find out students' thought process in solving quadratic equation problems based on mathematical reasoning ability. The type of research used is qualitative research, and uses a descriptive approach. The source of data in this research is class IX students totaling 22 students with the subject selected 3 students. The data analysis technique in this research is qualitative data analysis. From the test results of students' mathematical reasoning abilities are categorized based on the assessment reference. Researchers categorized it into 3 categories, namely high, medium, and low. Based on the results of tests and interviews, students in the high category can fulfill 4 indicators well. Students in the medium category were only able to fulfill indicators 1 and 2 well, for indicator 3 could not be fulfilled well so they could not fulfill indicator 4. Subject 3 in the low category was only able to fulfill indicator 2 well. Indicators 1 and 3 were not well met.

This study aims to comprehensively analyze the improvement of students ' mathematical development ability through the concept of three zone learning, with the type of research is quantitative and quasi experiment design. Examples of research as many as two classes amounted to 82 pre service teacher. Data analysis by calculating gain normalization. Results: based on the Post Hoc test, the level of the category that has a positive score of 0.012 with the upper category and the middle category means that the average score of students from the upper category is better than the middle category, then also for the level that has a positive score of 0.028 with the upper category and the lower category which means that the average score of students from the upper category is better than the lower category. As for the positive value of 0.016 with the middle category and the lower category means the average of the middle category is better. From the results showed that for levels with upper, middle and lower categories, the effect is greater in improving students.

This study aims to evaluate the impact of using the Brainingcamp application in improving the understanding of arithmetic concepts among fourth-grade students at Islamic Leader School in Tasikmalaya City through a constructivist approach. The research employs a case study approach with qualitative descriptive design, involving 22 students as research subjects during the first semester of the 2024/2025 academic year. Data were collected through classroom observations, written tests (pre-test and post-test), and interviews with students and teachers. Qualitative data were analyzed using thematic analysis, while quantitative data were analyzed using descriptive statistics. The results show a significant improvement in students’ average scores after using Brainingcamp, with increases of 17.6% in addition, 18.8% in subtraction, 24.3% in multiplication, and 30.8% in division. Observations and interviews also reveal that students became more active, motivated, and collaborative during the learning process. The use of virtual manipulatives supports the principles of constructivism, aligning with Piaget’s and Vygotsky’s theories by providing opportunities for students to build their own understanding through visual exploration and social interaction. Based on these findings, Brainingcamp proves effective in enhancing both conceptual understanding of arithmetic and student engagement, although this study has limitations in terms of sample size, duration, and generalizability. Therefore, it is recommended to replicate the study with a larger and more diverse population and extend the duration of implementation in future research.

This study aims to determine the profile of students' mathematics anxiety based on the chosen elective class. The method used in this study is a survey method with data collection techniques involving observation (interviews or questionnaires). Participants were grade XI students of Public Senior High Schools in Tasikmalaya City in the 2023/2024 academic year, totaling 10 schools. The sample consisted of two classes from each school, consisting of one class specializing in science and one class specializing in social studies, selected using a purposive sampling technique. The instrument used was a mathematics anxiety questionnaire. Data processing techniques involved descriptive statistical analysis using Ms. Excel Nvivo version 14. The results of the study showed that there were differences in anxiety between students in science and social studies elective classes. The impression from these findings is the need for special interventions in the mathematics learning process in social studies classes to reduce mathematics anxiety.

The formation of students' character and self-confidence based on noble cultural values can be formed from the education and culture around students. Culturally responsive teaching makes people aware of respecting and recognizing the reality of different tribes, religions, languages and ethnicities, and exploring the special aspects or uniqueness of students' culture and using them in planning and implementing learning. Development efforts are still very necessary, because: 1) Education is not enough to develop teacher professionalism. Many teachers take distance education/study outside the city. 2) Community Service Activities as an effort to organize education. 3) Cultural fusion as a border area. 4) Learning with a cultural background so that it can be introduced in learning. The solutions to partner problems that are addressed are: 1) The mixing of Javanese and Sundanese cultures as areas on the border is no longer considered a problem with the existence of acculturation (mixing of cultures) through the marriage process which has been carried out for a long time and produces Javanese and Sundanese descendants 2) Cultural conflict is not an obstacle because cultural acculturation has occurred in various activity sectors including religious and school activities using the language of instruction in both regions, so that it can be accepted by both parties in its delivery. 3) Community Service Activities are expected to be an implementation that can minimize inequality in technological progress and cultural inequality. 4) Culturally Responsive Teaching in daily learning is introduced by teachers through the Project Based Learning teaching module.

The low level of students’ mathematical problem-solving ability remains a major issue in mathematics learning, particularly when instructional practices fail to actively engage students and to integrate cultural contexts relevant to their daily lives. This study was motivated by the limited integration of the Inquiry Learning Model with the Culturally Responsive Teaching (CRT) approach, especially within Islamic boarding school settings, and by the suboptimal achievement in solving problems related to the System of Linear Equations in Three Variables. This research aimed to examine (1) whether there is a significant effect of the Inquiry Learning Model integrated with CRT on students’ mathematical problem-solving ability, and (2) the magnitude of such an effect. A quasi-experimental method with a posttest-only control group design was employed. The population consisted of all tenth-grade female students of SMA Terpadu Riyadlul ‘Ulum in the 2025/2026 academic year. Samples were selected through purposive sampling and cluster random sampling, resulting in class X-1 as the experimental group and class X-4 as the control group. The instrument was an essay test constructed based on Polya’s four problem-solving indicators and validated by experts. Data were analyzed using the Shapiro–Wilk normality test, Levene’s homogeneity test, Independent Samples t-test, and coefficient of determination. The findings revealed a significant difference between the experimental and control groups (p = 0.000 < 0.05). The coefficient of determination (R² = 0.436) indicates that 43.6% of the variance in mathematical problem-solving ability was explained by the applied learning model, which falls into a moderate effect category. Thus, the integration of the Inquiry Learning Model with the CRT approach significantly enhances students’ mathematical problem-solving ability and is recommended as an effective contextual learning alternative in mathematics education.
