Abstract

Innovation in interactive learning media is essential to improve the effectiveness of statistics instruction at the junior high school level. This study aimed to develop interactive learning media based on WPS Office to support Statistics learning for eighth-grade junior high school students. The research employed the ADDIE development model, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The media was designed using WPS Presentation and Canva, and then converted into an Android application using Website 2 APK Builder Pro. Validation was conducted by media and subject experts; practicality was assessed by teachers and students. Validation results showed very high feasibility, with an average score of 94.32% from media experts and 95.37% from subject experts. Practicality testing yielded scores of 95.33% from teachers and 93.42% from students, indicating that the media is highly practical and engaging. The developed media is valid, practical, and relevant for supporting contextual and interactive digital learning. It has potential to improve students' conceptual understanding of statistics and their digital literacy.

Abstract

Mathematics is often perceived as abstract and disconnected from students’ daily lives, yet ethnomathematics highlights that mathematical ideas are embedded in cultural practices. This study explores the ethnomathematical concepts found in the preparation of Ilabulo, a traditional food of Gorontalo, Indonesia, through a qualitative ethnographic approach involving observation, documentation, and informal interviews with two local participants. The findings reveal two main concepts: ratio and proportion in mixing ingredients and geometry in wrapping and shaping, both of which were mapped to relevant school mathematics topics and further developed into contextual word problems. In addition, the study suggests that the process of preparing Ilabulo can be adapted into a video-based learning resource to support the problem-orientation stage in Problem Based Learning (PBL). These results demonstrate that everyday cultural practices can serve as meaningful contexts for mathematics learning, making abstract concepts more engaging and relevant while also strengthening students’ cultural identity.
