Abstract

The learning model is a teacher's tool in the form of structured images that are presented to students. The learning model applied aims to improve students' understanding of mathematical concepts. The author determines the purpose of this study. Namely to assess the impact of experiments on the subject's knowledge of mathematical concepts in geometry material. This type of research uses experimental research using a mind mapping learning model with a pre-experimental design, one-group pretest-posttest. Tests were carried out randomly or through cluster sampling on building materials class VII Realschule. The data collection tool that the researchers used for this research was a test designed to test students' understanding of concepts. The researcher interviewed teachers, students, and documents in this data collection method. A hypothesis test was carried out on the data obtained after conducting a sig5% level t-test, normality test, and homogeneity test on statistical data. It was found that students could not understand mathematical concepts (mind mapping). This dramatically influences the results of understanding mathematical concepts. After using this method, students receive higher performance scores than before. Based on the t-test results, we can conclude the difference in the value of learning outcomes before and after applying the author's teaching method.

Abstract

This study aims to explore junior high school students' experiences in using Question Card media in algebra learning. Using a qualitative approach, this study involved 26 students of grade VII B at SMP Darul Ulum 5 Rebalas as the main participants. Data were collected through classroom observations, interviews, and student response questionnaires to understand perceptions, engagement, and challenges faced during the learning process using Question Cards. The results showed that Question Card media was able to increase students' interest, attention, and engagement in algebra learning. Most students stated that using Question Cards made learning more interactive, enjoyable, and helped them understand abstract algebraic concepts. Data analysis showed that the level of student learning interest was in the high category (74.7%), with indicators of engagement and attention also showing high percentages. However, there were some students who still felt more comfortable with conventional methods, so further adaptation was needed. These findings confirm that Question Card media can be an innovative alternative in mathematics learning, especially algebra, to enhance students' learning experiences actively and meaningfully. This study recommends the development of similar media and training for teachers to optimize the use of interactive media in mathematics learning at the junior high school level.
