Abstract

This study aims to develop a flipbook-based e-module on linear programming material for students that meets the criteria of validity, practicality, and effectiveness, making it suitable for learning. This study uses the Research and Development (R&D) method with the ADDIE development model which includes five stages, namely: Analysis, Design, Development, Implementation; and Evaluation. The research instruments included an expert validation sheet, a student response questionnaire, and a learning outcome test. The e-module's validity was assessed by subject-matter, media, and language experts using a 1–5 Likert scale, yielding an average score of 126 (max 135), indicating very high validity. Practicality was measured through student responses on ease of use, display, and learning benefits, with 52.5% rating it as very practical and 47.5% as practical. The e-module's effectiveness was assessed based on student learning outcomes, with a mean of 90.25 and 97.5% achieving scores above the Minimum Completion Level (≥75). The results indicate that this flipbook-based e-module is valid, practical, and effective for use in linear programming lectures. Consequently, this e-module has the potential to improve the quality of mathematics learning, particularly in understanding linear programming concepts, and to encourage student independence in learning through an interactive, accessible presentation of materials.

Abstract

Effective mathematical representation is a fundamental component of mathematical problem-solving; however, many students experience persistent difficulties in developing this ability. This study aims to (1) examine differences in students’ mathematical representation abilities between those taught using the reciprocal teaching–learning model and those taught through direct instruction, (2) compare mathematical representation abilities among students with high, medium, and low self-esteem, and (3) investigate the interaction between learning model and self-esteem. This study employed a quantitative approach with a quasi-experimental design using a nonequivalent posttest-only control group. The experimental class consisted of 5 students with high self-esteem, 24 with medium self-esteem, and 3 with low self-esteem, while the control class included 6, 20, and 6 students in the respective categories. Data were analyzed using a two-way ANOVA. The results indicate that (1) students taught through the reciprocal teaching–learning model demonstrated significantly higher mathematical representation abilities than those taught using direct instruction, (2) mathematical representation abilities differed significantly across levels of self-esteem, and (3) there was no significant interaction between the learning model and self-esteem. In conclusion, the reciprocal teaching–learning model is more effective than direct instruction in enhancing students’ mathematical representation abilities, regardless of their self-esteem levels. The contribution of this study lies in providing empirical evidence that reciprocal teaching–learning can serve as an effective instructional model for strengthening mathematical representation skills while clarifying the independent role of self-esteem as an affective factor in mathematics learning.
