The Development of Dominika Card with a Problem-Solving Approach for Mathematical Learning Interest

Abstract Drawing on the needs of teachers and students for innovative and engaging learning media, the Dominika card game was developed using a problem-solving approach. The research aims to describe the process and result of the development of the media. The type of research is R&D with the ADDIE model. There are 24 students in Al Bukhori Middle School that used as research subjects. The data collection methods are tests, interviews, observation, questionnaires, and documentation, with the analysis using presentation and t-test using SPSS. The result of the research suggests that the process of the develop as follows: analysis, design, development, implementation, and evaluation. Where the media is feasible, practiced, and effective in improving the mathematical learning interest, and is used as a mathematics learning medium for multiplication and division of integer materials. With an average validity of 3.65, the media is valid and fit for use. And so, the average response is 80% means the media is practiced. After that, for the effectiveness of the media, the results show a significant effect of media use (p < 0.05). The recommendation of the media can be developed in electronic form. Next, it is necessary to have smaller numbers so that the calculation process is easier and faster, and lastly, the material used on Dominika cards is not durable, so it is necessary to use materials that are not easily damaged, such as printed PVC cards.
