Abstract
This research aims to: 1) develop the Prezi application media for mathematics learning on the topic of spatial structures in elementary schools, 2) describe the feasibility of the Prezi application media for mathematics learning on the topic of spatial structures in elementary schools through the validation assessment by media experts and subject matter experts. The use of the Prezi application media to display sound media, animated movements, and images falls under the Research and Development (R&D) category. The research conducted by the researcher consists of several stages: (1) information and research collection, (2) media production planning, (3) initial product development, (4) preliminary product testing, (5) validation by media experts and subject matter experts, (6) product revision, and (7) final product design. The data collection techniques used in this study include observation, questionnaires, and interviews. Two instruments are utilized: assessment sheets for subject matter experts and media experts. Qualitative and quantitative analysis techniques are employed to analyze the collected data, converting average scores into categorized values. The research and development results include: 1) utilizing Prezi to create a learning media product for mathematics on the topic of spatial structures with engaging and interactive features, and 2) the feasibility of the Prezi media, as assessed by media experts, is 80%, categorized as "Good" and deemed feasible. According to subject matter experts, the feasibility of the Prezi media obtained a score of 75%, categorized as "Good" and deemed feasible. Media experts' validation results for the Prezi application media yielded a "Good" rating. Based on the above explanations, the development of Prezi-assisted learning media for spatial structures in the sixth grade at Godegan Elementary School is suitable for mathematics learning.
