Abstract

This study aims to develop Problem-Based Learning (PBL) teaching materials for algebra content in Junior High School (SMP). The research method used is Research and Development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The results of the study indicate that PBL-based teaching materials can improve students' understanding of algebraic concepts and critical thinking skills. The trial was conducted on eighth-grade students at SMP negeri 3 Depok, with results showing a significant increase in students' final test scores compared to before using the PBL-based teaching materials.

Abstract

This study examines the implementation of the Project-Based Learning (PjBL) model through a miniature ecosystem project to enhance the creativity of fifth-grade students at SD Negeri Winajaya III. The research employed a quasi-experimental design with a pre-test and post-test group. The results revealed a significant improvement in students' creativity after implementing the PjBL model. Students demonstrated increased abilities in designing, developing, and evaluating projects. Additionally, PjBL facilitated collaborative and independent learning. These findings highlight the relevance of PjBL to the Merdeka Curriculum, which emphasizes project-based learning to foster 21st-century skills.
