Abstract

This study aims to evaluate the effectiveness of the Group Investigation (GI) cooperative learning model in enhancing students' interest and achievement in mathematics at SMP Unggulan Aisyiyah Bantul. The background of this research is the low interest and achievement in mathematics among students, who often perceive mathematics as a complex subject. The GI model was chosen for its potential to foster active collaboration and deep understanding. The research method used is Classroom Action Research (CAR), with two cycles, each consisting of two meetings. The research sample involved 28 students participating in online learning implementing the GI model. Data were collected through pretests and posttests to measure learning outcomes and questionnaires to assess students' interest in learning. The results showed a significant increase in students' learning outcomes after implementing the GI model. In the first meeting of the cycle I, the average posttest score reached 87.89, an increase of 7 points from the pretest. In the second meeting of cycle II, the average posttest score reached 98.93, an increase of 1.07 points from the previous meeting. Additionally, students’ interest in learning showed consistent improvement across enjoyment, attention, interest, and engagement indicators. In the second meeting of cycle II, 86% of students reported feeling very happy, 64% showed excellent attention, 61% exhibited very high interest, and 61% demonstrated very high engagement. In conclusion, implementing the Group Investigation cooperative learning model effectively improves students’ learning outcomes and interest in online mathematics learning. The integration of technology, such as the Zoom platform, supports effective collaboration in virtual environments and facilitates interactive learning that enhances material comprehension.

Abstract

The current cultural context has become a significant focus in mathematics education, serving not only as a bridge to formal understanding but also as a means of cultural preservation. This study aims to analyse the use of Palembang's cultural context in mathematics education through the Indonesian Realistic Mathematics Education (PMRI) approach. The analysis was conducted on articles indexed in Scopus and Google Scholar based on publication year, content, methods, student skills developed, and research findings. Data analysis techniques were based on the PIECES framework (Planning, Identifying, Evaluating, Collecting/Elaborating, Explaining, and Summarising). From the selection process, 20 articles that met the inclusion criteria were obtained. The analysis results showed that the dominant cultural context of Palembang included traditional food (pempek), traditional fabrics (songket and jumputan), and trading activities on the Musi River. The most frequently studied mathematical topics were geometry and algebra, with the design research method used as an approach to design learning and develop media such as worksheets, educational videos, and evaluation instruments. The students' ability most frequently focused on was conceptual understanding. These findings provide significant contributions to educators and researchers in developing context-based cultural mathematics learning through the PMRI approach.

Abstract

This study analyzes the influence of the Articulation Learning Model on students’ mathematics learning. The research employed a quasi-experimental design using a pretest–posttest control group format, involving 7th-grade students from a private junior high school in Lubuk Linggau. The data were analyzed using a t-test, after confirming that the assumptions of normality and homogeneity were met. The Kolmogorov–Smirnov test yielded p = 0.067 and Levene’s test yielded p = 0.625, both greater than 0.05, indicating that the data were normally distributed and homogeneous. The independent t-test showed a p-value of 0.000 (p < 0.05), indicating a significant difference between the experimental and control groups. The mean score of the experimental group was 87, while that of the control group was 66. These results demonstrate that the use of the Articulation Learning Model had a strong positive effect on students’ mathematics learning outcomes, particularly in the topic of statistics.

Abstract

Mathematics education in Indonesia continues to face challenges in accommodating diverse student characteristics and connecting mathematical concepts with meaningful cultural contexts. Uniform and procedural teaching practices often hinder the development of conceptual understanding and mathematical literacy. Although differentiated instruction and the integration of local wisdom have been discussed extensively, studies that systematically integrate both within digital mathematics learning media remain limited. This study aims to develop and evaluate BATIK BEKAL (Learning Mathematics through Local Wisdom), a web-based mathematics learning platform integrating differentiated instruction with Kasumedangan local wisdom. The study employed a Research and Development (R&D) approach using the ADDIE model. Participants included 50 mathematics teachers involved in the needs analysis and 25 junior high school students in a limited classroom implementation. Data were collected through questionnaires, expert validation instruments, classroom observations, and semi-structured interviews. The results indicate that the developed platform demonstrates high pedagogical, technical, and cultural validity and is perceived as practical by both teachers and students. The integration of local wisdom functions as a conceptual scaffold within differentiated mathematics learning. These findings contribute to the development of culturally responsive and adaptive digital mathematics learning media.
