Abstract

This research aims to 1) Identify the needs of math digital teaching materials, 2) Design digital teaching materials for mathematics, 3) Measure the level of validity, 4) Measure the level of practicality, and 5) Measure the level of effectiveness. This research uses an R&D (Research and Development) approach. The development model used, namely ADDIE. This research was conducted at SMP Negeri 4 Sungguminasa class VII. The developed digital teaching materials were validated by material experts and media experts. Trials on 1 teacher, 3 students (individual) and 12 students (small group) to see the practicality of digital teaching materials. Meanwhile, 45 students were involved in the effectiveness test learning. The results of the level of validity of digital teaching materials from the assessment of media expert validators (98.3%) are at a very valid stage and material experts (92.5%) are at a very valid stage. The results at the practicality level obtained (range 91-94%) which was declared very practical. Furthermore, the level of effectiveness of digital math teaching materials was measured by a pretest which obtained 54 in the “low” category and the posttest obtained 91 in the “high” category which showed an increase in student learning outcomes so that it was declared very effective. Based on the results of the analysis, it can be concluded that digital math teaching materials are proven to be valid, practical, and effective in improving student learning outcomes.

Abstract

Rapid technological advances in education have increased student engagement, but some schools still struggle with optimal understanding of mathematical concepts, which impacts learning outcomes. The purpose of this study was to create and evaluate web-based learning multimedia that can improve students' understanding of mathematical concepts. We conducted research and development involving fourth-grade elementary school students. A small-scale trial with six students aimed to observe student responses to the use of web-based learning multimedia in mathematics. Meanwhile, large-scale trials were conducted in three elementary schools with a total of 69 students. Validation involved media and design experts as well as material experts. Data were analyzed quantitatively using percentages and the Wilcoxon test. Interview results revealed a conventional learning process with minimal student participation and limited use of technology. Students tended to be more interested in the use of interactive media, such as videos and images, in the learning process. The results of media validation showed a very good validity level (96.25%), and material validation also showed a very high validity level (90.1%). The measurement results showed that teachers and students responded well, with a percentage above 80%. It indicates that the web-based learning multimedia is very practical. Effectiveness analysis indicates that the developed product effectively improves elementary school students' understanding of mathematical concepts (sig. < 0.05). This study concludes that the developed product, namely web-based learning multimedia, meets the standards of validity, practicality, and effectiveness in improving elementary school students' understanding of mathematical concepts.
