ABSTRACT
This research was conducted based on the results of observations and interviews on the low critical thinking skills of students in elementary school cluster 9 Pasawajo sub-district which had an impact on student learning outcomes. The purpose of this study was to analyze the differences in the effectiveness of the multiple intelligences-based discovery learning model with the discovery learning model on the science critical thinking skills of fifth grade elementary school students. This type of research uses quantitative methods with a quasi experimental design that applies experimental and control classes. Data collection techniques were carried out by observing, giving tests, student response questionnaires and documentation. The samples of this study were the fifth grade students of SDN 113 Buton as the experimental class and the fifth grade students of SDN 91 Buton as the control class. The research instrument was conducted by first analyzing the results of the test trials including the validity of the reliability, the level of difficulty, and the differentiating power of the questions. The data analysis technique used was normality test, homogeneity test, completeness test and hypothesis testing using independent sample t-test after which the gain test is carried out. The results of the study can be concluded that there was a significant difference in the effectiveness of students' critical thinking skills between the multiple intelligences-based discovery learning model and the discovery learning model. The results of the average difference test using the independent sample t-test obtained a sig value. (2-tailed) the experimental and control classes were 0.000 < 0.05, so Reject H0 which means that there are differences in critical thinking skills. The results of classical completeness using the Z test obtained that the experimental class achieved more than 75% completeness and the control class was less than 75%. The data results from the experimental class gain test obtained a gain value of 0.56 higher than the control class with a value of 0.42 even though both classes were in the medium gain category, but the experimental class increased higher than the control class.
