Abstract

The effectiveness of implementing online learning during the COVID-19 pandemic has not been satisfactory in terms of problem-solving abilities. The presentation of teaching materials presented in the online platforms used has not been able to identify the extent of student understanding in problem-solving exploration. Therefore, this research aims to produce Kaizala teaching materials based on problem-solving exploration. The ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model was used in this research to produce these teaching materials. The subjects of this research trial were grade VIII junior high school students in a public school in Ogan Komering Ulu Regency, Palembang. The choice of the place for this research was based on the fact that the mathematics learning carried out at the school was by utilizing social media platforms. The instruments used in this research consisted of validation sheets of material, language, presentation, and problem-solving integration, a questionnaire on the practicality of teaching materials, and a problem-solving ability test to assess the effectiveness of the developed teaching materials. The results showed that: (1) the developed teaching materials were in the valid criteria; (2) the practicality of the developed teaching materials are at very high and high criteria; (3) The developed teaching materials also meet the criteria of effectiveness, whereas many as 82 percent of the test subjects obtained a score of not less than 75 and the effect size value belongs to the large category. Thus, it can be concluded that the developed teaching materials are suitable for supporting and facilitating students in problem-solving exploration activities.

Abstract

The integration of technology and pedagogy in mathematics learning remains a significant challenge, particularly in supporting students’ understanding of abstract concepts such as statistics. This study aims to develop and evaluate the validity and practicality of a Digital Smart Book based on the Realistic Mathematics Education (RME) approach for eighth-grade students. The research employed a Research and Development (R&D) design using the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The study involved expert validators in content, media, and instructional design, as well as students participating in one-to-one evaluation (3 students), small group evaluation (8 students), and field testing (33 students). Data were collected through observations, interviews, and Likert-scale questionnaires, and analyzed using descriptive statistics and percentage-based feasibility criteria. The results indicate that the developed Digital Smart Book achieved a high level of validity, with an average score of 90%, categorized as very good. Specifically, content validity reached 94.5%, instructional design 89%, and media validity 87%. In terms of practicality, the product consistently showed very good results across all testing stages, with scores of 90% in one-to-one and small group evaluations, and 91% in field testing. These findings demonstrate that the Digital Smart Book is both valid and practical for use in mathematics learning. The integration of RME principles within a digital interactive medium supports meaningful and contextual learning experiences. This study contributes to the development of innovative digital learning media that align with student-centered learning and the demands of 21st-century education.
