Development of Jumanji-Based Board Game Media to Improve Critical Reasoning in Fourth Grade Elementary School Students

Abstract

The independent curriculum requires students to be more advanced in critical reasoning skills, and one of the subjects that requires critical reasoning skills is mathematics. However, mathematics is one of the subjects that students are less interested in, therefore researchers developed a Jumanji-based board game media to improve the critical reasoning abilities of fourth grade elementary school students. This research uses the Research and Development (R&D) method with the ADDIE development model type, namely Analyze, Design, Development, Implementation and Evaluation. The ADDIE development model was chosen because the research steps are more effective so the time required is shorter. Based on the research that has been carried out, the Jumanji-based board game media is a learning medium that is suitable for application because it has gone through a validation stage by media experts and material experts. The results of the feasibility analysis by media experts obtained an average percentage of 88.5% with very feasible criteria. Meanwhile, the feasibility results by material experts obtained an average percentage of 92% with very feasible criteria. Research also proves that Jumanji-based board game media can increase students' interest in learning and critical reasoning abilities. In the recapitulation of the student interest in learning questionnaire, an average score of 89.98 was obtained with a percentage of 80.3% and was in the very interested criteria. Meanwhile, in the pre-test recap, students obtained an average score of 80.2 with very high criteria and the average score in the post-test recap was 85.2 with very high criteria. It is hoped that the results of the development of this Jumanji-based board game media can become an effective medium in supporting the learning process, so that learning objectives are more easily achieved.
