Abstract

To support the achievement of Sustainable Development Goal 4 regarding quality and equitable education, the development of innovative science learning models is crucial for early childhood in underdeveloped regions, such as the Indonesia-Papua New Guinea border. Disparities in educational access in border areas often hinder the optimization of children's cognitive potential during their golden years. This study aims to analyze the effectiveness of a neuroscience-based Reflective Inquiry Learning (RIL) model to improve Executive Function (EF) in preschool children. The intervention was implemented through two cycles of Classroom Action Research (CAR) involving 40 preschool children, utilizing data triangulation to assess behavioral changes across the cycles. Quantitative analysis using paired t-tests showed highly statistically significant improvements (p < 0.05$) from the baseline to the completion of the second cycle across all domains, particularly in socio-emotional (+32.70%) and language (+25.60%) skills. The most prominent EF enhancements were observed in emotion regulation (+35%) and inhibitory control (+30%), indicating improvements in executive functions associated with neuroplasticity-related learning processes. In conclusion, the neuroscience-based RIL model serves as an effective and practical pedagogical intervention to optimize EF and support holistic child development in remote border regions

Abstract

Project-Based Learning (PjBL) serves as a robust pedagogical framework to engage students in solving real-world contextual problems through empirical evidence and collaborative innovation. This study seeks to analyze the creativity of prospective chemistry teacher students in voltaic cell learning through the implementation of PjBL using local organic resources. By adopting a mixed methods design method with a repeated measures design, the study involved 10 prospective chemistry teachers enrolled in the Basic Chemistry 2 course at Universitas Cenderawasih, Jayapura, Indonesia. Research instruments included observation rating scales for creativity, pre-test and post-test assessments for conceptual mastery, and a Likert-scale perception survey to evaluate professional motivation. The results demonstrated a significant positive impact across all measured dimensions. An analysis of student creativity showed that 60% of students were "creative," 30% were "very creative," and 10% were "quite creative," especially when it came to how fluently and originally they used local plant. Furthermore, a high-category Normalized Gain (N-gain) of 0.76 validated pedagogical effectiveness, indicating a substantial increase in conceptual mastery of electrochemical principles. Technical analysis confirmed that indigenous resources, such as local lime, provided stable voltage suitable for series circuit engineering to power electronic loads. Finally, the perception survey showed a very high score (4.95/5.00) for professional intent, reflecting a strong motivation to replicate this "living laboratory" model in future careers. This ethnochemistry-based PjBL approach effectively transforms local environments into authentic scientific laboratories, fostering resourceful, innovative, and culturally responsive science educators in resource-constrained regions
