Abstract

This research study is focused on developing the VAKSIN (Animated Video for Online Learning System) design, which aims to facilitate independent asynchronous learning in the introductory geometry course. The research methodology employed is based on Plomp's general educational problem-solving model, involving three out of five phases: initial investigation, design, and realization phases. Subsequent studies are planned to include testing, evaluation, revision, and implementation phases. The findings of the research indicate the feasibility of using VAKSIN in the Introductory Geometry course.

Abstract

Mathematics learning in junior high schools often faces challenges such as low conceptual understanding and limited teacher collaboration. Android-based Lesson Study (LS) offers a promising solution through technology integration, but related research is still scarce. This study analyzes the potential of Android-based LS for mathematics learning in junior high schools based on Scopus-indexed literature. A systematic literature review (SLR) was conducted using the PRISMA protocol. Searches in Scopus used the keywords "Lesson Study," "Android app," "mathematics education," and "secondary school," filtered by: (1) 2019–2024 publications, (2) journal articles only, and (3) full-text availability. Of 78 articles identified, 15 met the inclusion criteria. Results show: (1) 80% highlight Android apps’ effectiveness in improving teacher collaboration; (2) 60% report enhanced student motivation via interactive media; (3) main challenges involve teachers’ TPACK and infrastructure. The study concludes Android-based LS has strong potential for junior high schools, especially with adequate TPACK training.

Abstract

Mathematics olympiads require higher-order thinking skills, logical reasoning, and mastery of non-routine material, one of which is combinatorics, a topic often considered difficult by students. Limitations in face-to-face coaching have encouraged the need for structured independent learning media that align with the characteristics of olympiad problems. This study aims to examine the effectiveness of the Math Universe application on students’ conceptual understanding of combinatorics in mathematics olympiads. The study employed a quantitative approach with a one-group pre-test–post-test design. The research subjects consisted of 40 students who were members of the Komunitas Pecinta Matematika (KPM). The research instrument was an olympiad-level combinatorics test administered before and after the use of the Math Universe application. Data were analyzed using a paired sample t-test. The results showed a significant difference in learning outcomes before and after the use of the Math Universe application. These findings indicate that Math Universe is effective in improving combinatorics learning outcomes through independent learning based on self-directed learning and mobile learning. This application has the potential to serve as a supporting medium for mathematics olympiad training, particularly for materials with a high level of complexity.
