Abstract

This study aims to develop a valid, practical, and effective instructional design to improve students’ mathematical problem-solving abilities on the topic of addition and subtraction. The study was motivated by the lack of structured learning trajectories and the low level of students’ problem-solving skills in elementary mathematics. This research employed a Design research method by combining the Plomp development model and the Gravemeijer and Cobb model, consisting of three phases: preliminary research, development or prototyping, and assessment. The effectiveness of the developed design was examined through a field test using a one-group evaluation design involving second-grade students at SDN 26 Bukit Putus Dalam and SDN 20 Muara Jambu. Data were collected through observation, questionnaires, documentation, and tests, and analyzed using qualitative and quantitative techniques. The results indicate that the developed instructional design is highly valid (96.25%), very practical (93.22%), and effective in improving students’ mathematical problem-solving abilities, as shown by the increase in students’ performance during the implementation phase

Abstract

This study was conducted due to the limited integration of interactive digital teaching materials in fifth-grade mathematics learning, which has led to low student engagement and suboptimal learning outcomes. Mathematics instruction is still predominantly delivered through printed modules and conventional methods, limiting students’ opportunities to actively explore concepts. Therefore, developing innovative and student-centered digital learning resources is essential. This study aimed to develop a STEAM-based interactive e-module that is valid, practical, and effective for teaching nets of cubes and rectangular prisms in accordance with the Merdeka Curriculum. This research employed the Research and Development (R&D) method using the ADDIE model. The subjects were fifth-grade students from SDN 24 and SDN 12 Pincuran Tujuah. Data were collected through expert validation, practicality questionnaires, and pretest–posttest assessments. The results showed that the e-module achieved a very high level of validity, with scores from media experts (90.52%), material experts (94%), and language experts (95.55%). Practicality results indicated very high responses from teachers (97.69%) and students (96.98%). Effectiveness testing showed a significant improvement in learning outcomes, with a high N-Gain Score. Thus, the developed e-module is valid, practical, and effective for enhancing mathematics learning.
