This research was motivated by the lack of teaching materials that align with the characteristics and needs of students. One of the main issues identified is the use of learning modules that are not yet adapted to local culture and fail to provide meaningful learning experiences. To address this problem, the researcher developed a culturally based module inspired by Minangkabau songket. This study employed a Research and Development (R&D) design following the development stages proposed by Sugiyono. The results show that the developed module achieved a validity level of 82.58% (categorized as very valid), a practicality level of 87.6% (very practical), and an effectiveness level of 83.3% (very effective). Based on these findings, it can be concluded that the ethnomathematics-based module on Minangkabau songket for Phase F of the Health Department at SMAN 1 Lareh Sago Halaban in the 2023/2024 academic year meets the criteria of being valid, practical, and effective. Therefore, it is considered suitable for use as a culturally contextual teaching material that integrates local values into the learning process.

Education is a crucial foundation for shaping a generation with strong character, faith, intelligence, and responsibility as mandated by Law Number 20 of 2003. In the 21st century, one of the most essential competencies to be developed is critical thinking, which can be effectively nurtured through Project Based Learning (PjBL). This approach actively engages students in planning, inquiry, problem-solving, and reflection within project-based tasks, making learning more meaningful. This study examines the effect of PjBL on the critical thinking skills of fifth-grade students in Natural and Social Sciences (IPAS) at SD Islam Istiqomah, Ungaran Barat, Semarang Regency. Employing a quantitative method with a quasi-experimental Nonequivalent Control Group Design, the study involved 76 students divided into experimental and control groups. Data were collected using a validated and reliable essay test on critical thinking skills. Results showed that the experimental group achieved a higher mean posttest score (84.16) than the control group (74.74). The point-biserial correlation was rpb = 0.676, and the t-test result (tcount 7.891 > ttable 1.993, p < 0.05) confirmed a significant difference. These findings demonstrate that PjBL substantially improves students’ critical thinking and emphasize its continued implementation to foster contextual and meaningful IPAS learning.

This study explores the alignment between science learning practices and children’s cognitive development stages based on Jean Piaget’s theory. Ten academic publications were systematically reviewed to examine how Piaget’s framework can be applied in science education. The findings highlight that integrating cognitive development theory is highly relevant for improving the quality of teaching and learning in schools. At the concrete operational stage (approximately 7–11 years), children learn best through direct experiences, manipulation of real objects, contextual media, and experiments that connect concepts with daily life. These methods help foster curiosity and reinforce conceptual understanding. As learners progress to the formal operational stage (around 11 years and above), they begin to think abstractly, reason logically, and analyze critically. At this level, student-centered approaches, inquiry-based methods, and constructivist learning become more effective in enhancing problem-solving, creativity, and higher-order thinking skills. The review also indicates that adapting instruction to developmental stages supports more meaningful and sustainable learning outcomes. In the Indonesian educational context, this approach can address challenges such as limited classroom facilities, diverse student learning styles, and a curriculum that is often overloaded. By applying Piaget’s insights, teachers can design learning strategies that bridge abstract concepts with concrete understanding, thus increasing student motivation and engagement. In conclusion, aligning science education with Piaget’s cognitive stages is an effective way to improve student performance and ensure long-term academic growth. The study provides valuable input for teachers, researchers, and policymakers in developing innovative, student-centered science and mathematics education.

This research aims to develop an electronic student worksheet (E-LKPD) based on Liveworksheet, integrated with Quizwhizzer, for teaching economic activities in elementary school. The background of this study stems from the limited variation in learning activities and the underutilization of digital technology in the learning process at schools. To address these problems, the study seeks to produce innovative, interactive, and easily accessible learning media that can support student engagement and improve learning outcomes. The development process follows the ADDIE model, consisting of five stages: Analyze, Design, Development, Implementation, and Evaluation. In the analysis stage, the needs of students and teachers were identified. The design and development stages involved creating E-LKPD content integrated with Liveworksheet and interactive quizzes using Quizwhizzer. The implementation was carried out through classroom trials, followed by evaluation to assess the effectiveness and feasibility of the product.

This community service activity was carried out as an effort to improve the effectiveness of reporting and withholding of Income Tax (PPh) Article 21 at the Kosayu Credit Cooperative through accounting-based technical assistance. The main problem identified during the Field Work Practice (PKL) activity was the potential for tax overpayments caused by inaccurate estimates of employee annual income and limitations of the payroll system used by the cooperative. To address these problems, the implementation team implemented several methods, namely direct observation of the tax administration process, technical training for related staff, tax calculation simulations based on actual data, and evaluation of the existing tax recording and reporting system. The results of the activity showed that although the cooperative had used the Average Effective Rate (TER) method for withholding PPh 21, its implementation was still not optimal because it was not supported by an integrated information system and a regularly updated employee database. This resulted in inaccuracies in tax calculations and withholding. Therefore, this assistance recommended several improvements, including updating the payroll system, improving employee data, integrating the digital tax reporting system, and increasing the capacity of the cooperative's human resources through ongoing training related to tax regulations. In addition to having a direct impact on the efficiency of cooperative tax management, this program also provides contextual learning benefits for students in linking tax accounting theory with real conditions in the field.

Early science education has a strategic role in forming critical and innovative thinking patterns in children as a provision to face challenges in the era of globalization and technological advancement. However, the implementation of the scientific approach at the early childhood education (PAUD) and elementary school levels still faces various obstacles, such as limited teacher knowledge, lack of contextual learning facilities, and teaching methods that tend to be one-way. In fact, childhood is a phase of cognitive development that is very potential to foster curiosity and scientific thinking skills. The low science literacy scores of Indonesian students in international studies indicate the need for intervention from an early age. Therefore, community service programs that aim to build a foundation for children's science from an early age are very important. This program includes teacher training, development of learning media, and exploratory activities based on simple experiments that are appropriate to the world of children. Through this approach, it is hoped that a young generation can be created who not only understand science conceptually, but also have the ability to think critically, creatively, and find solutions in facing problems in the future.
