Abstract : Perpustakaan Tuanku Bainun

This study aims to develop PolyCompass for the polygon topic and to evaluate its validity and usability among students. The research design adopted the Design and Development Research (DDR) approach, combined with the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model, to ensure a systematic development process. The research involved 140 Form Two students who were selected through simple random sampling. Two instruments were employed: the PolyCompass Validation Forms and the PolyCompass Usability Form. Expert evaluation revealed that PolyCompass achieved a perfect Content Validity Index value of 1.00, indicating complete agreement among experts regarding the clarity, relevance, and suitability of its content. Usability analysis, based on mean scores, produced an average of 3.95, confirming PolyCompass has a high level of usability as a teaching aid. In conclusion, the developed PolyCompass demonstrates satisfactory validity and a good level of usability. This indicates the potential of PolyCompass to be used in the classroom to enhance teaching and learning for the topic of polygons. Consequently, PolyCompass demonstrates significant potential to enrich the teaching and learning of polygons. Its positive impact extends beyond students and teachers to school authorities and the Ministry of Education Malaysia (MoE), reinforcing its value as an effective educational innovation.
