Development of Interactive Multimedia Using Word Wall Through Problem-Based Learning (PBL) Model in Science and Social Subjects

This research is motivated by the suboptimal use of available IT resources in schools by teachers. There is a lack of development of innovative, interactive, and engaging media for students, as well as the absence of technology-based learning media. Therefore, teachers need to improve their ability to create technology-based instructional media to prevent student boredom. The Problem-Based Learning (PBL) model has also not been previously applied in the use of instructional media, especially those based on technology. Based on these issues, this study aims to develop an interactive multimedia learning media using Word Wall and the Problem-Based Learning (PBL) model for Science and Social Subjects (IPAS) learning in grade IV of elementary school that is valid, practical, and effective. This research is a type of Research and Development (R&D) using the ADDIE model. The ADDIE model consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The designed media was validated by experts using validation sheets in the form of questionnaires. Product validation was carried out by content experts, media experts, and language experts. Practicality was assessed through teacher and student response questionnaires. Finally, effectiveness was measured by giving evaluation tests to students.
