Abstract

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.

Abstract

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.
