<![CDATA[This study aimed to determine the effect of the Problem Based Learning (PBL) model assisted by Mind Maps on the learning outcomes of fourth-grade students at SDN Karangjaya 02 in the topic of economic activities. This research was motivated by the low learning outcomes of students, which were related to the use of learning approaches that were less varied and had not fully involved students in solving problems during the learning process. Therefore, an interactive learning approach such as Problem Based Learning assisted by Mind Maps was needed to help students understand economic activities more actively and systematically. This study employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The sample consisted of 22 students in the experimental class and 22 students in the control class, selected using a purposive sampling technique. Data were collected through pretests and posttests and analyzed using the normality test, homogeneity test, and the Independent Samples t-test with the assistance of IBM SPSS Statistics software. The results showed that the mean posttest score of the experimental class was higher than that of the control class. The hypothesis test yielded a significance value (Sig. (2-tailed)) of 0.000 (< 0.05), indicating that H₀ was rejected and H₁ was accepted. Therefore, it can be concluded that the Problem Based Learning model assisted by Mind Maps had a significant effect on students' learning outcomes in the topic of economic activities for fourth-grade students at SDN Karangjaya 02.]]>
