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.

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.

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.

This study aimed to investigate the effect of the Discovery Learning model integrated with a Culturally Responsive Teaching (CRT) approach on students’ mathematical understanding of systems of linear equations in two variables. An experimental method with a posttest-only control group design was employed. Data were collected using an essay-type test of mathematical understanding developed based on established indicators of mathematical comprehension. The population consisted of all ninth-grade students of SMP Negeri 8 Tasikmalaya in the 2025/2026 academic year, comprising 11 classes. Samples were selected through simple random sampling, resulting in class IX-J as the experimental group and class IX-H as the control group. Data analysis involved prerequisite tests of normality and homogeneity, followed by hypothesis testing using an independent samples t-test. The results showed that the Discovery Learning model integrated with the CRT approach had a significant effect on students’ mathematical understanding compared to Direct Instruction with a scientific approach. The t-test yielded a calculated value of 4.189 exceeding the critical value of 1.672, leading to the rejection of the null hypothesis. The coefficient of determination indicated that the treatment accounted for 23.23% of the variance in students’ mathematical understanding.Keyword: CRT, Discovery Learning, Mathematical Understanding Ability.
