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.
