Abstract

The primary objective of this study was to explore how the Mind Mapping instructional approach influences the creative thinking abilities of fourth-grade students in mathematics. This research utilized a quantitative method employing a quasi-experimental design involving two distinct groups: one serving as the experimental group and the other as the control group. The study was conducted at SDN Karadenan, with a sample of 24 fourth-grade students participating in the experimental group and 29 students from SDN Paledang in the control group, selected through purposive sampling. The main focus was to assess the impact of the Mind Mapping approach on students' creative thinking skills in mathematics. Data was collected using the t-test method. The mean difference between the two groups was 4.89 (experimental group = 66.70 and control group = 52.65), indicating that the Mind Mapping approach was more effective compared to traditional lecture methods, question-answer sessions, and assignments. The findings were statistically significant (p = 0.000) based on Independent Sample T-Test analysis. As the significance level (0.000) was less than 0.05, the null hypothesis was rejected, confirming that the Mind Mapping approach significantly enhances creative thinking skills in mathematics among students. Thus, it can be concluded that the Mind Mapping instructional model has a substantial positive impact on students' creative thinking abilities in the context of mathematics.

Abstract

The instructional model is a crucial component in the educational process. This study evaluates the effectiveness of the Group Investigation learning model in enhancing students' mathematics outcomes. A quantitative research method with a One Group Pretest-Posttest design was used, involving 29 eighth-grade students. Data were analyzed using SPSS version 25, revealing a pretest score of 0.010 and a posttest score of 0.063 after implementing the Group Investigation model. The average posttest score was 77.91, indicating a significant impact on learning outcomes. Observations over three sessions showed an increase in student participation from 26.97% with an average score of 2.24 in Session I (categorized as "Less Active") to 42.79% with an average score of 3.56 in Session II, and 45.38% with an average score of 3.78 in Session III (both categorized as "Active"). This increase demonstrates that the Group Investigation model not only enhances student participation but also makes students more active in learning, thereby improving mathematics outcomes. Therefore, the Group Investigation model is an effective strategy for enhancing students' achievement in mathematics. Further research with more refined methods and tools is needed to confirm these findings.
