Development of a Learning Model Combining Learning Environment and Project-based Learning (LE-PROBALE Model) through Nila’s Edumath Interactive Mobile Learning

Introduction: This study focuses on the development, validation, and implementation of the LE-Probale learning model, which integrates technology-based scaffolding to foster mathematical literacy among junior high school students. The model is designed to enhance students' ability to understand and apply mathematical concepts by utilizing "Nila’s Edumath Interactive Mobile Learning," a digital tool that supports interactive learning. The research follows a modified version of the Plomp model (1997) for educational development, involving five key phases: initial investigation, design, realization, testing and evaluation, and implementation. The initial investigation phase identified a gap in students' mathematical literacy and the need for innovative teaching models. Objectives: The design phase focused on formulating the syntax, social systems, reaction principles, and support systems of the LE-Probale model. Methods: The realization phase involved developing the teaching materials, digital tools, and assessment instruments. The model was validated by expert reviewers and tested through field trials in a junior high school, with teachers and students actively participating. Results: The results of the field trials demonstrated that the LE-Probale learning model is both practical and effective. Students showed significant improvement in mathematical literacy, with the interactive scaffolding approach helping them construct and integrate mathematical concepts more efficiently. Teachers also reported positive feedback regarding the usability of the model in their classrooms. Conclusions: The study concludes that the LE-Probale learning model, with its integration of technology-based scaffolding, offers a valuable approach to enhancing mathematical literacy. The model can be adapted across various mathematical topics and is ready for broader implementation in junior high schools.
