This study aims to develop an innovative learning media called “Detective Data” as a tool to enhance students’ motivation and understanding in learning statistics, particularly the concepts of mean, median, and mode. The development of this media was driven by findings indicating that many students perceive statistics as abstract and uninteresting. Therefore, the Project-Based Learning approach was combined with gamification elements to create an investigative learning experience through real data collection activities and statistical analysis. The research was conducted with 33 eighth-grade students at SMP Negeri 33 Makassar. A descriptive approach with a limited trial was employed, using observation sheets, student response questionnaires, and product assessment rubrics as instruments. The results showed that the use of “Detective Data” successfully increased students’ learning motivation, engagement in the learning process, and their ability to analyze data. The investigative posters produced by students demonstrated a solid understanding of data presentation and statistical analysis. Thus, this media can be effectively implemented as a project-based learning tool for statistics instruction.

This study aims to analyze the effect of applying the Problem Solving learning model assisted by GeoGebra on students’ mathematics learning outcomes, specifically in the topic of translation. The research employed a quasi-experimental approach using a pretest–posttest control group design involving two ninth-grade classes at SMP Negeri 3 Tondano with a total of 27 students. The experimental class received learning through the Problem Solving approach integrated with GeoGebra, while the control class was taught using conventional methods. The research instrument consisted of a five-item essay test designed to measure students’ understanding of translation concepts. Data analysis included normality and homogeneity tests to ensure that both groups met the statistical assumptions required for further analysis, followed by an independent t-test to determine differences in learning outcomes. The results show that the experimental group achieved a higher posttest mean score of 90.77, whereas the control group obtained a mean score of 66.43. The independent t-test produced t_count = 12.26, which was greater than t_table = 1.70 at a 0.05 significance level. These findings indicate that the use of the Problem Solving model assisted by GeoGebra significantly improves students’ mathematics learning outcomes. The integration of GeoGebra helps students visualize translation concepts more effectively, thereby enhancing comprehension and supporting problem-solving skills.

ANALISIS KEMAMPUAN PEMAHAMAN MATEMATIS SISWA DENGAN MENGGUNAKAN PENDEKATAN PMRI

Anesty G Hutajulu — 2026-04-01

This study aims to analyze students’ mathematical understanding through the implementation of the Indonesian Realistic Mathematics Education (PMRI) approach. The background of this research focuses on the still low ability of students to comprehend mathematical concepts deeply, particularly in connecting representations, interpreting information, and applying concepts in contextual situations. The PMRI approach was chosen because it emphasizes the use of real contexts and modeling processes, allowing students to construct their own understanding. This study employed a qualitative descriptive method with secondary school students as subjects. Data were collected through mathematical understanding tests, classroom observations, and interviews. The understanding indicators analyzed included the ability to restate concepts, provide examples and non-examples, connect concepts, represent situations in mathematical models, and apply concepts in problem-solving. The results show that PMRI-based learning helps students achieve more meaningful understanding of concepts. Real-world contexts facilitate students’ initiation of the thinking process, while discussion and modeling activities support the development of more mature mathematical representations. However, some students still experienced difficulties at the stages of abstraction and generalization of concepts.

ANALISIS FAKTOR PENYEBAB RENDAHNYA PEMAHAMAN ALJABAR SISWA DAN SOLUSI PEMBELAJARAN KOLABORATIF BERBASIS TEKNOLOGI

Nurhana — 2026-04-01

Algebra is a fundamental element in developing abstract thinking abilities and problem-solving skills. However, for many secondary school students, it becomes one of the most challenging areas of mathematics learning. This article seeks to investigate the main factors contributing to students’ low mastery of algebraic concepts while also offering relevant pedagogical approaches. Based on a review of various literature sources, it is identified that difficulties in learning algebra arise from a combination of factors, both internal such as weak prerequisite knowledge and low learning motivation and external such as unvaried teaching strategies and limited use of visual media. To address these issues, this article proposes a Technology-Supported Collaborative Learning model as an alternative solution. The integration of social interaction within group collaboration and technology-based visualization is believed to strengthen conceptual understanding, enhance student engagement, and reduce anxiety in learning mathematics.
