UNESA 5 Math Gallery: Math Interactive Digital Learning Media Curative for Students Across 9-14 Years Old

Indonesia's socio-economic status (SES) makes it difficult for fourth- to eighth-graders to learn multiplication, geometric forms, and basic mathematics due to insufficient resources and outdated teaching methods. Math topics are abstract and complex, thus engaging virtual learning resources that match with the curriculum are needed to bridge the gap between passive instruction and active, student-centered learning. To meet this need, the UNESA 5 Math Gallery is an interactive virtual gallery that leverages Artsteps to teach basic math through 3D models, films, and quizzes. This medium uses ADDIE-based ‘curative’ involvement to improve understanding. Active inquiry, formative evaluation, and feedback help students overcome past misconceptions through constructive refinement, using audio-visual elements. The gallery improves motivation, spatial thinking, independent guided learning, self-assessment, and mastery for advanced math skills. This study also examines its usability, learner participation, and academic performance in Indonesian classrooms. Results show that the UNESA 5 Math Gallery's virtual learning tools reduce regional math instruction discrepancies, motivate students, and ensure equitable access to quality materials.
