Abstract

This study aims to investigate the effect of guided inquiry learning model on critical thinking skills of tenth grade students at SMA Pencawan Medan. Using a quantitative approach and experimental method, this study involved two classes as samples, namely the experimental class that implemented the guided inquiry learning model and the control class that used conventional learning methods. Hypothesis testing was conducted to compare the average post-test scores between the two classes, with the results showing that the average post-test score of the experimental class was higher, namely 72.02, compared to the control class which only reached 59.52. The results of the study showed a significant difference in critical thinking skills between students taught with the guided inquiry model and students taught with conventional methods. The ????-h???????????????????? value of 3.538 is higher than the ????-???????????????????? value of 2.002, which indicates that the implementation of the guided inquiry learning model has a positive influence on students' critical thinking skills. Thus, guided inquiry learning can significantly improve students' critical thinking skills at Pencawan Medan High School, making students more active, independent, and confident in understanding and applying mathematics material.

Abstract

This research, conducted in grade VII of UPT SMPN 41 Medan, aims to describe the effect of Connected Mathematics Project (CMP) learning on students' mathematical connection abilities in the topic of triangles and quadrilaterals. The research method used a quantitative approach with a quasi-experimental research method. The population in this study was all grade VII students of UPT SMPN 41 Medan. The sampling technique used random sampling, selecting grade VII-2 students as the experimental class and grade VII-4 students as the control class. The Pretest and Posttest results were analyzed using normality and homogeneity tests. Based on the normality and homogeneity tests, the results showed that the sample was normally distributed and homogeneous. Furthermore, a hypothesis test was conducted. The results of the independent samples test showed a significant difference in students' mathematical connection skills between the control and experimental classes. The SPSS analysis showed a significance value of p = 0.000, indicating that p <0.05, indicating an effect of the Connected Mathematics Project (CMP) learning on students' mathematical connection skills. This was also evident from the results of the comparative hypothesis test of two samples, with an average post-test score of 74.55 for the experimental class and an average score of 46.28 for the control class, with a T-value of 13.87. This T-value was higher than the T-table value of 2.001. Therefore, the hypothesis Ho was rejected and Ha was accepted. Therefore, it can be concluded that the Connected Mathematics Project (CMP) learning had a significant effect on students' mathematical connection skills.
