The Development of Interactive 3D Multimedia Based on Problem-Based Learning in ”Denah Tempat Tinggalku” Material for the Third-Grade Elementary School

Abstract

The learning process, as often presented in conventional models, and the lack of media, lead to exploitation, resulting in students' learning outcomes not being completed. This study aims to describe the design, determine the validity results, and assess the effectiveness of three-dimensional interactive multimedia based on problem-based learning in the social sciences content of my residence plan for grade III elementary school. This study uses the ADDIE development model, which consists of the stages of analysis, design, development, implementation, and evaluation. Data collection is carried out using non-test methods (questionnaires) and test methods. The results of this development research are (1) the design of three-dimensional interactive multimedia based on problem-based learning developed in accordance with the flowchart and storyboard based on the ADDIE development model flow diagram to produce products that can be accessed via Google Drive. (2) The findings of this development research consist of three main results. First, a three-dimensional interactive multimedia product based on problem-based learning was successfully designed using the ADDIE model, outlined through a flowchart and storyboard, and produced as a digital learning resource accessible via Google Drive. Second, the validation results indicate that the multimedia is highly valid, with expert scores of 94.64% for content, 93.75% for instructional design, 93.18% for media, 94.79% from practitioner review, 96.52% from individual testing, and 94.67% from small-group testing. Third, the effectiveness test using a one-sample t-test shows that the obtained value (t_count = 4.053) exceeds the critical value (t_table = 1.734) at the 5% significance level, demonstrating that the 3D interactive multimedia based on problem-based learning for the IPAS content “My Residential Layout” is effective for use in elementary school learning.
