Abstract

The aim of this study was to develop a traditional market context-based e-book as a digital learning resource to support mathematics learning and students’ mathematical reasoning in Class X TKRO 1 at SMK Negeri 2 Padangsidimpuan. This study employed a Research and Development (R&D) approach using the ADDIE development model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. In the Analysis stage, learning needs, curriculum requirements, student characteristics, and problems related to students’ mathematical reasoning were identified through observation and literature review. In the Design stage, the e-book framework, mathematics learning materials, layout, and contextual learning activities were designed by integrating traditional market situations into mathematics learning. In the Development stage, the e-book was developed based on the designed framework and subsequently validated by two material experts and two media experts, followed by revisions based on their suggestions. In the Implementation stage, the revised e-book was implemented with 30 students of Class X TKRO 1 at SMK Negeri 2 Padangsidimpuan to obtain student responses regarding its use in mathematics learning. In the Evaluation stage, formative evaluation was conducted throughout the development process, while summative evaluation was based on expert validation results and student responses to determine the feasibility of the developed e-book. The research instruments consisted of material and media expert validation questionnaires and student response questionnaires. The results showed that the e-book obtained an average material expert validation score of 87.5% and a media expert validation score of 85.0%, both categorized as very feasible. Student responses obtained an average score of 84.3%, which was also categorized as very feasible based on the criteria used in the study. These findings indicate that the developed traditional market context-based e-book meets the very feasible category and can be used as a contextual digital learning resource for mathematics learning at vocational high schools.
