Abstract

Research exploring the perceptions of public university employees in Cambodia regarding job satisfaction and academic service quality revealed significant insights. Using a quantitative design with a sample of 336 staff from three Phnom Penh universities, the study found that employees reported a high perception of both their job satisfaction and the academic services they provide. On average, staff felt more satisfied with their jobs than they rated the quality of academic services, although both were perceived positively. This suggests that job satisfaction is a slightly stronger factor. A key finding was the confirmed positive relationship between the two variables, indicating that the perception of academic service quality increases as job satisfaction increases. This correlation highlights the crucial link between employee well-being and the quality of education services. The research, driven by the need to enhance the education sector, provides valuable insights into employee morale and the current state of academic services within the Cambodian public university system, underscoring the importance of focusing on staff satisfaction as a strategy for improving educational offerings.

Abstract

This study investigates thei effect of the Project-Based Learning (PjBL) model on eighth-grade students’ mathematical critical thinking skills, considering their cognitive styles. The research employed a quasi-experimental design with a non-equivalent control group, involving eighth-grade students of SMP Negeri 24 Kerinci in the 2023/2024 academic year. The sample comprised two experimental classes taught with the PjBL model and one control class taught conventionally. Data were collected using the1 Group Embedded Figures Test (GEFT) to identify students’ cognitive styles and an essay test to measure critical thinking skills. Data analysis was conducted through a two-way ANOVA to examine the effects of the learning model and cognitive style, followed by a t-test for further comparison. The results showed that the PjBL model and students’ cognitive styles significantly influenced mathematical critical thinking skills. Field Independent (FI) students scored higher than Field Dependent (FD) students. However, no significant interaction was found between the learning model and cognitive style, indicating that PjBL provides relatively balanced opportunities for all learners. These findings suggest that PjBL can be an effective and inclusive instructional approach to foster students’ critical thinking, and mathematics teachers are encouraged to integrate it into classroom practice.

Abstract

This study aimed to address eighth-grade students' low conceptual understanding and problem-solving skills in learning flat-sided solid figures by applying the STAD learning model assisted by Powtoon. A quasi-experimental method with a Nonequivalent Control Group Design was employed, with samples selected using cluster sampling from SMP Muhammadiyah 01 Medan. Research instruments consisted of pretest and posttest essay questions. The results showed that the experimental class obtained a higher mean N-Gain score of 0.65 (medium category) than 0.38 (medium category) in the control class. The independent samples t-test revealed that the difference was statistically significant (t = 3.142, df = 48, p = 0.003 < 0.05, t-table = 2.011). These findings indicate that implementing the STAD model, assisted by Powtoon, effectively enhanced students’ conceptual understanding and mathematical problem-solving skills. Moreover, it suggests that cooperative learning supported by interactive animations can serve as an effective alternative to foster more active, collaborative, and meaningful mathematics learning in secondary schools.

Abstract

Conceptual understanding is essential in geometry, yet many students struggle with rotation concepts due to a lack of contextual learning materials. This study aims to develop ethnomathematics-based student worksheets (LKPD) by integrating the Serampang Dua Belas dance movements as a rotation representation. The worksheets were tested on 37 ninth-grade students at an Islamic junior high school in Serdang Bedagai Regency using the ADDIE development model. Validation results from subject matter and media experts scored 89% (highly valid), while teacher and student responses indicated 89% (efficient). Effectiveness was demonstrated with an N-Gain of 0.77 (high category), and 82% of students scored ≥75. These findings confirm that the developed LKPD is valid, practical, and effective, offering an innovative learning tool that bridges mathematics with local culture and has the potential to be adapted to other cultural and mathematical contexts.

Abstract

Limited student understanding of contextual mathematical concepts remains a key issue in learning. This study aims to identify and analyze mathematical concepts in the preparation of traditional foods Alame and Lemang from Padang Lawas using an ethnomathematics approach. A qualitative descriptive-exploratory method was employed, with data collected through observation, semi-structured interviews, and documentation. Data analysis was conducted using the interactive model of Miles, Huberman, and Saldaña and validated through triangulation and member checking. The results indicate that Lemang preparation involves spatial geometry, geometric transformations, and heat distribution, while Alame applies ratios and proportions of ingredients, traditional measurement, and time and temperature estimation. Both techniques reflect principles of algorithm, order, and efficiency. These findings confirm that traditional culinary practices can serve as contextual mathematics learning media while contributing to the preservation of local culture.

Abstract

This study examines ethnomathematical practices in a home-based peanut-cake (kue kacang) business and draws implications for teaching social arithmetic. Using a descriptive-qualitative, ethnographic approach, data were collected through observation, interviews, and documentation with the business owner, Mrs. Mardiana Rangkuti (Medan, Indonesia). Analysis reveals that key social-arithmetic concepts are embedded across procurement, processing, packaging, and sales, including gross, tare, and net calculations, unit conversions, pricing, profit, and profit percentage, with minimal risk of loss. Daily records indicate a profit rate of 233.52% relative to production costs, illustrating how routine commercial decisions operationalize mathematical reasoning. The study translates these authentic practices into context-rich classroom tasks (e.g., computing net weight from gross and tare, comparing pricing strategies, and evaluating profit percentages under varying input costs). The novelty lies in integrating local cultural and economic activities into mathematics instruction, enabling students to connect formal social arithmetic concepts with real-life contexts. This approach is expected to improve conceptual understanding, relevance, and engagement in learning social arithmetic.

Abstract

This study aims to develop interactive learning media for the Pythagorean Theorem based on ethnomathematics using the architecture of the Medan Grand Mosque as a learning context. This research is motivated by students' low interest and understanding in mathematics, especially in the Pythagorean Theorem material. The development method used is the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The validation results indicate that the media obtained a highly feasible category, with an average score of 92.5% from media experts and 91% from material experts. The teacher and student responses were 88% and 79.95%, respectively, based on practical criteria. The effectiveness test through N-Gain obtained an average value of 0.520 (moderate category). These results suggest that interactive media based on ethnomathematics can enhance students' understanding of mathematical concepts and provide more engaging learning experiences by connecting the material to local culture.

Abstract

This study aims to address the low mathematics learning outcomes of eighth-grade students in flat-sided shapes lessons by applying the NHT learning model. The method used is quantitative with a quasi-experimental approach. Sampling was conducted using cluster random sampling from SMP Muhammadiyah 01 Medan. The research design used was a control group. The research instruments were pretest and posttest essay questions. The results showed that the experimental class obtained a higher average N-Gain score of 0.790 (high category) compared to the control class, which obtained a lower average N-Gain score of 0.445 (medium category). The hypothesis test results from the N-Gain data yielded a t-count of 6.025, which is greater than the t-table value of 1.668 at a significance level of 0.05. Therefore, it can be stated that Ha is accepted. These findings suggest that the application of the NHT model significantly enhances students' mathematics learning outcomes. This suggests that cooperative learning, supported by the NHT model, can be an effective alternative for encouraging more active, collaborative, and meaningful mathematics learning in junior high schools.
