Abstract

Javanese context is rich of phenomena potentially used as a starting point to learn mathematics. On the other hand, the Indonesian students’ performance in PISA is consistently low due to the small number of PISA-like problems which can be used to foster the students’ mathematical literacy measured in PISA. Therefore, this research aims to develop a set of PISA-like problems using the Javanese context targeted for 8th-grade students of Junior High School. It is a development study using Plomp’s framework in the stage of need analysis and prototyping. We have successfully developed a prototype of PISA-like mathematics problems using Javanese context. There are six items covering seven basic competences in the 8th-grade of junior high school. The items used various mathematics skills such as communication, representation, mathematization, devising strategies, and reasoning. We could explore some Javanese contexts such as traditional building, transportation, calendar system, community meeting, and historical place. Meanwhile the school mathematics materials include number sequence, Cartesian coordinate, relation, linear function, linear equation system in two variables, and Pythagorean theorem.

Abstract

This study synthesizes empirical research on Mathematical Knowledge for Teaching (MKT) in elementary teacher education through a systematic review combined with a limited meta-analytic synthesis. Following PRISMA 2020 procedures, studies published between 2015 and 2025 were identified from ERIC, Scopus, Google Scholar, Garuda Kemdikbud, and DOAJ. Fourteen quantitative and mixed-methods studies met the inclusion criteria, although only five provided sufficient statistical data for effect size estimation. Effect sizes were calculated using Cohen’s d and Hedges’ g, and pooled under a random-effects model in CMA version 3 and the R-package metafor. The findings indicate that MKT among elementary teachers, both prospective and early-career, is generally uneven across domains, with stronger performance in common content knowledge and persistent weaknesses in specialized content knowledge and horizon content knowledge, especially in fractions and geometry. The pooled effect (d = 0.62, 95% CI [0.38, 0.86], k = 5) suggests that structured pedagogical interventions can improve MKT, although the evidence base remains limited and heterogeneous. Cross-study patterns, rather than formal subgroup meta-analytic tests, suggest that teaching experience, mathematical content domain, and initial pedagogical knowledge are associated with variation in MKT outcomes. The study highlights implications for strengthening elementary teacher education curricula, particularly within the Kurikulum Merdeka framework in Indonesia, and for improving future MKT research design and reporting.

Abstract

Household organic waste remains a serious problem in Indonesia, particularly in urban areas that produce large amounts of waste. The inadequate utilization of kitchen waste, such as vegetable scraps and fruit peels, leads to environmental pollution and potential health problems. Independent waste processing into liquid organic fertilizer is an environmentally friendly solution that is effective and applicable using fermentation solutions. This program aims to educate and foster knowledge and skills in making liquid organic fertilizer from kitchen waste. This community service activity was carried out in Dukuh Lemusir, Pabelan Village, Kartasura Regency, targeting 19 women from the Family Welfare Movement (PKK) as the main partners (divided into 5 groups). The implementation included preparation, outreach, training, monitoring, and evaluation. Evaluation through questionnaires measured knowledge and skills analyzed using quantitative descriptive methods. The training focused on hands-on practice in making liquid organic fertilizer, conducted in groups with intensive guidance. The fermentation results were observed for approximately 30 days and indicated a successful process with characteristics such as brown color, a distinctive fruity aroma, an acidic pH, and no mold. The evaluation results showed an average achievement of 93.68%, categorized as very good. Contributing to reducing waste and environmental pollution, the use of liquid organic fertilizer also supports organic farming and reduces dependence on chemicals. This education and training is expected to encourage the sustainability of environmentally friendly waste management practices in the community and strengthen the government's integrated waste management program.

Abstract

The Indonesian performance in PISA mathematics consistently low in the last decade, despite the increasing awareness among mathematics educators regarding the importance of mathematical literacy. One of the core problems is the lack of mathematical literacy problems while the resources of contexts are available and rich. This research aims to develop a set of mathematical literacy problems using Jogja tourism context. It is an ADDIE research which includes the analysis, design, develop, implementation, and evaluation stage. We involved two mathematics educators as the experts to validate the problems and 441 junior high school students in Yogyakarta to try-out the problems. Finally, we successfully developed 35 valid items of mathematical literacy problems with Jogja tourism context in terms of content and construct. The availability of these word problems would be useful for mathematics educators to foster the students’ mathematical literacy at school.
