Development and Usability of “From Formulas to A+†SPM Mathematics Comprehensive Module among Upper Secondary School Students

The research aims to develop and evaluate the validity and usability of the “From Formulas to A+†Malaysian Certificate of Education (SPM) Mathematics Comprehensive Module, covering Kurikulum Standard Sekolah Menengah (KSSM), which is the Malaysian National Secondary School Standard Curriculum, Mathematics topics from Form 1 through Form 5. Targeted at Upper Secondary students, the module seeks to enhance their understanding of mathematics and support effective teaching and learning sessions. The study adopts a Developmental Research Design (DRD) and utilizes the ADDIE model as its instructional framework. The ADDIE model Analysis, Design, Development, Implementation, and Evaluation systematically creates educational materials. Content validity was assessed using the Content Validity Index (CVI), ensuring alignment with educational standards and objectives. Feedback from four experts with over five years of teaching experience confirmed the module’s content validity, achieving a perfect CVI score of 1.00. The research used structured questionnaires, including the Module Validity Questionnaire and Module Usability Questionnaire. A pilot study was conducted with 30 Form 4 students from a school in Pasir Gudang, Johor, selected through convenience sampling. The usability questionnaire achieved a high-reliability score, with a Cronbach’s alpha of 0.881. Usability results showed an overall mean score of 3.6406 across usefulness (3.6533), ease of use (3.6625), ease of learning (3.5222), and satisfaction (3.6571). These findings suggest that the module is highly usable and effective in supporting the learning of KSSM Mathematics topics. The study demonstrates that the “From Formulas to A+†module not only meets educational standards but also significantly fosters active learning. Its originality lies in the comprehensive coverage of the entire KSSM syllabus and its use of the ADDIE model for systematic instructional design, contributing valuable insights to mathematics education research.
