Abstract

This research aims to develop a game "GEMAS (Modified Division Engklek Game)” to improve understanding of concepts for class II elementary school students that meet the criteria of valid, practical and effective. This research uses R&D research with the ASSURE development model. Participants in this research were 16 students. Data collected through questionnaires and tests. The collected data was analyzed through descriptive statistics, paired sample t-test and n-gain test. Based on the research results, it shows that the game GEMAS very worthy to use, where the average score from the validation results of media experts is 99% and material experts 77% . The results of the analysis are related to the practicality of the game GEMAS very practical, where the teacher response was 99% and student response was 99,4%. Based on the test scores for understanding the concept of division, the average results were obtained pretest 62 and posttest 85,44 there was an increase of 0,64 in the medium category. As well as the results of the paired sample t-test, the Sig value was obtained. (2-tailed) of 0,000 < 0,05. So, it can be concluded that game media GEMAS can be declared effective in increasing students' understanding of the concept of division.

Abstract

This research is motivated by the low mathematical representation ability of elementary school students, particularly in the data presentation material. Students are still experiencing difficulty in communicating mathematical ideas visually, symbolically, and verbally. This condition is exacerbated by a learning process that tends to be conventional, a lack of media innovation, and the unavailability of technology-based teaching materials that support representation skills. Therefore, this research aims to develop mathematics E-LKPD based on the Realistic Mathematics Education (RME) model to improve students' representation abilities. This research was conducted at MI Al-Ishlah Bobos, involving 36 fifth-grade students as respondents. The method used in this research is Research and Development (R&D), referring to the ADDIE development model, which consists of five main stages: 1) Analysis, 2) Design, 3) Development, 4) Implementation, and 5) Evaluation. Based on the validation results from the expert team, the following media feasibility levels were obtained: media experts 96%, language experts 93%, and content experts 100%, all of which fall into the very valid category. After making improvements to the media and content based on validator feedback, the researcher proceeded to the implementation stage with 36 fifth-grade students. The results of this implementation showed that the media received a score of 70%, which falls into the "good" category.
