Abstract

This study aims to examine the implementation of the Quantum Teaching model as well as measure its impact on improving mathematical reasoning of fourth grade students of SDN Rogomulyo 02 Kayen Subdistrict, Pati Regency for flat area material. The pre-experimental one-group pretest-posttest design was applied to 30 students. The instruments applied included mathematical reasoning tests, learning motivation questionnaires, and observation sheets. The findings indicated an increase in the mean score from 60.58 in the pretest to 81 in the posttest. The t-test confirmed the significance with a p value = 0.001, which is smaller than 0.05, as well as an N-Gain score of 0.53, which is in the moderate category. About 83.33% of students showed high to very high levels of learning motivation. Observations also noted a consistent improvement in the application of the TANDUR model and student engagement. Overall, the Quantum Teaching model proved effective in improving mathematical reasoning skills through interactive and meaningful learning experiences.

Abstract

The purpose of this study was to determine the effect of the PBL model assisted by mind mapping on students' critical thinking skills. The background of this study is the low critical thinking skills of fourth grade students of SDN Kalicari 02 Semarang. This is because students' ability to remember material is very low. There are still students who cannot conclude the contents of the learning in class and the learning model has not been used by the teacher when teaching. This study uses quantitative research in the form of Pre Experimental Design with One Group Pretest-Posttest Design. The population in this study were all fourth grade students of SDN Kalicari 02 Semarang in the 2024/2025 academic year. The sample used in this study was 27 students with a saturated sampling technique. The data in this study were obtained through observation, interviews, and tests. Then the data analysis used the normality test and the t-test (paired sample t-test). The results showed that the average pretest score was 50.93 and the average posttest score was 83.52. The results of the data above show that the average posttest score is higher than the pretest score. This is also proven by the results of the t-test hypothesis test obtained a Sig. (2-tailed) value of <0.000 <0.05, meaning that the significance value in the pretest and posttest is less than 0.05. So H0 is rejected and Ha is accepted. So it can be concluded that there is a significant influence of the PBL model assisted by mind mapping on the critical thinking skills of grade IV students of SDN Kalicari 02 Semarang.
