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 motivated by the need for innovative, interactive, and digitally integrated mathematics learning materials to improve the quality of instruction in elementary schools. The purpose of this study is to develop and evaluate the validity, practicality, and effectiveness of a STEAM-based mathematics teaching module supported by Google Sites for Grade V elementary school students. This research employed a Research and Development (R&D) method using the Plomp development model, which consists of three phases: preliminary research, prototyping stage, and assessment phase. The preliminary research phase involved needs analysis, curriculum analysis, analysis of students’ characteristics, and learning material analysis. The prototyping stage focused on designing and developing the STEAM-based teaching module supported by Google Sites, followed by self-evaluation and expert validation by material, media, and language experts. The assessment phase was conducted through limited trials, including practicality testing by teachers and students as well as effectiveness testing to determine the usefulness of the module in Grade V mathematics learning. The results showed that the STEAM-based teaching module supported by Google Sites achieved a very high level of validity, with validation scores of 95% for material, media, and language aspects. The module was also classified as very practical, with practicality scores of 98% in the small group trial and 97% in the field test. Furthermore, the effectiveness test yielded a score of 94%, indicating that the module is effective for use in Grade V elementary school mathematics learning.
