<![CDATA[This research aims to determine the effectiveness of the discovery learning model assisted by interactive PowerPoint on the social studies critical thinking abilities of class V students at SDN 9 Mataram. This research is research with a quantitative approach that analyzes the effectiveness of variable x (discovery learning model assisted by interactive PowerPoint) on variable y (critical thinking skills). The research method used is the Pretest-Posttest Control Group Design method. The subjects in this research were all class V students at SDN 9 Mataram where class VA was an experimental class with a total of 30 students while class VB was a control class with a number of 31 students. The data collection techniques used in this research were tests and observation, the research instruments used were, namely essay test question sheets (pretest and posttest) and observation sheets on the implementation of the discovery learning model assisted by interactive PowerPoint. The data analysis technique begins with a prerequisite test, namely the normality test using the Kolmogrov Smirnov test with a significance level of 5% (0.05) and continues with the homogeneity test using the Levene test. Next, test the hypothesis using the independent sample t test. Based on calculations for hypothesis testing at a significance level of 5%, t-count = 2.458, while t table = 1.67065, so t count > t table and the 2-tailed sig value is 0.00 < 0.05, so the alternative hypothesis (Ha) is accepted and the hypothesis zero (H0) is rejected. This means that the discovery learning model assisted by interactive PowerPoint is effective in improving the social studies critical thinking skills of class V students at SDN 9 Mataram.]]>
