Abstract

The present study analyses the needs and readiness for implementing Science and Social Studies (IPAS) learning based on Project-Based Learning (PjBL) integrated with local wisdom values, particularly the Toba Nauli cultural philosophy, at the elementary school level. Motivated by the low science literacy of Indonesian students as revealed in the 2022 PISA results and the lack of contextual relevance in IPAS content, the research adopts a mixed-methods design combining qualitative and quantitative approaches. Data were collected through interviews, classroom observations, document analysis, and Likert-scale questionnaires involving 20 teachers and 40 students across four elementary schools in Medan. The research results show that teachers have a positive perception of the importance of PjBL and science literacy, as well as a high belief in the relevance of Toba Nauli values in IPAS learning (M = 4.20; SD = 0.68). However, the limitations of teaching modules, lack of training, and low use of local media have made cultural integration in learning not optimally implemented. On the other hand, students show high enthusiasm for project-based learning. However, their actual experience with learning incorporating local culture is minimal (only 15% of students reported having experienced it). These findings indicate a significant potential yet to be realised within the current IPAS learning system. Therefore, this research recommends developing a PjBL-based IPAS learning model that incorporates the Toba Nauli philosophy as a foundation for the local context to enhance students' science literacy in a meaningful, contextual, and culturally rooted manner. These findings are expected to serve as a conceptual and empirical foundation in designing transformative learning innovations in elementary schools.

Abstract

This study aims to develop and implement an integrated learning model combining Project-Based Learning (PjBL) and Guided Inquiry Learning (GIL) to enhance science literacy in students within the advanced science education course. The study was conducted to students from the Elementary School Teacher Education Program at the Catholic University of Santo Thomas, focusing on the topic of States of Matter. A quasi-experimental design with a pre-test – post-test control group design was employed, where the control group received conventional teaching methods, and the experimental group engaged in the integrated PjBL-GIL model. The results reveal a significant difference in science literacy improvement between the groups. The experimental group, using the integrated PjBL-GIL model, showed a greater improvement (22.4%) compared to the control group (7.7%). Statistical analysis using a two-sample t-test confirmed the significance of this difference, with a t-value of 5.16 and a p-value of 0.000, indicating a statistically significant improvement in the experimental group. The effect size, measured by Cohen's d, was 2.53, indicating a large effect. ANCOVA results showed that even after controlling for baseline differences, the experimental group still demonstrated significantly higher post-test scores (p-value = 0.000). Furthermore, Pearson’s correlation analysis revealed a significant positive relationship between collaboration and science literacy improvement (r = 0.62, p = 0.01), emphasising the importance of collaboration in enhancing learning outcomes. These findings suggest that the integrated PjBL-GIL model is effective in improving critical thinking, problem-solving skills, and the application of scientific concepts. And it is recommended that this model be expanded in science education in Indonesia to further improve the quality of learning and students' science literacy.
