This study aims to determine the effectiveness of the physics e-book of rotational dynamics in the traditional game of augmented reality-assisted tops in improving students’ critical thinking skills and visual representation. This type of research is Research and Development (R&D) using the ADDIE development model, namely analyze, design, develop, implement, and evaluate. This research design is pretest-posttest control group. The subjects of this study included 3 expert lecturers and 2 teachers for product validation, 5 expert lecturers and 2 teachers for instrument content validity, 254 students for the empirical validity of the instrument, 6 students for the product readability test and 81 students for the implementation test. The data analysis technique of this research is to test the feasibility of the product using a standard scale, for the content validity of the instrument using Aiken’s V, to analyse the items using the Partial Credit Model, and to test the effectiveness of the product using the general linear model (GLM). The results of this study indicate that the use of rotational dynamics physics e-books on traditional games of augmented reality-assisted tops is effective in improving critical thinking skills and visual representation of students with a large effect size category. © 2025 Sociedad Mexicana de Fisica.
