Abstract

This study departs from the difficulty of students in mastering geometry material and the results of the needs analysis on students who expect the presence of learning media that contain elements of games such as the game congklak This type of research is R & D with the ADDIE development model consisting of 5 stages namely analysis, design, development, implementation, and evaluation. Descriptive analysis is used to describe the results of CoMath media development using ADDIE development stages. The results of the material expert validation showed that the comath media obtained a percentage of 80% which was in the very valid category. While the results of media expert validation obtained a percentage of 74,55% which included the valid category. To assess the practicality of teaching aids seen from the results of the assessment of comath media from teachers and students. The percentage obtained from the teacher's assessment is 84.83% and the percentage of student assessment is 80%, both of which are in the very practical category. To see the effectiveness, it was analyzed from the results of observations during the trial and supported by the results of interviews with two VIII grade students. From the analysis, it can be concluded that the comath media developed is valid, effective, and practical

Abstract

Mathematical problem-solving ability is essential in mathematics learning. This study aims to describe the mathematical problem-solving ability of ninth-grade students in class IX.E at SMP Negeri 1 Indralaya on the topic of probability through the implementation of differentiated learning tailored to kinesthetic learning styles. This research is a descriptive study involving 20 students who tend to have a kinesthetic learning style, identified through a learning style questionnaire. The learning process was designed to include physical activities, hands-on experiments, and group work to match the characteristics of kinesthetic learners. Data were collected through a mathematical problem-solving test developed from problem-solving indicators, supplemented by observations and interviews. The results showed that students' mathematical problem-solving abilities learning were categorized as high (25%), medium (30%), and low (45%) where kinesthetic learners were categorized as low. Students experienced difficulties in several indicators of problem-solving, particularly in understanding problems, planning solution strategies, implementing problem-solving steps, and rechecking the results. Most errors occurred because students were not accustomed to identifying important information, connecting information to formulate solution plans, and evaluating the correctness of their answers. These findings indicate that kinesthetic learners still need more support and practice to develop systematic and reflective problem-solving skills in learning probability.
