<![CDATA[The purpose of this study is to develop and evaluate the feasibility of interactive multimedia learning integrating a deep learning approach for eighth-grade mathematics, particularly circle topics. A Research and Development (R&D) design was employed using the Lee and Owens instructional design model integrated with Tessmer’s formative evaluation. The development process translated mindful, meaningful, and joyful learning principles into interactive features, including contextual examples, exercises and feedback, reflection, enrichment, learner-controlled navigation, and differentiated learning support. Participants included three experts and eighth-grade students involved in one-to-one, small-group, and field-test evaluations. Data were collected through expert validation and four-point Likert-scale questionnaires, complemented by qualitative feedback, and analyzed descriptively using percentage-based criteria. Expert validation indicated very high validity for content (91.3%), instructional design (86.6%), and media quality (90.8%). Student evaluations also showed very good results in one-to-one (93.37%), small-group (90.71%), and field-test (91.59%) evaluations. The findings provide strong evidence of product validity and usability, as well as positive student perceptions regarding engagement, learner autonomy, learning support, and classroom practicality. The study contributes a pedagogically grounded model for integrating deep learning principles into interactive mathematics multimedia.]]>
