Abstract
The purpose of this study was to determine the comparison of extrapolation understanding between students taught by using Modified Free Inquiry Learning and Guided Inquiry Motodes at Physics Education Department, UIN Alauddin Makassar. The sample was selected by simple random sampling technique. The instrument of data collection used was an extrapolation understanding test, with descriptive data analysis and inferential statistics techniques namely independent sample T-2 test. Based on these using descriptive statistics was obtained the extrapolation understanding test results through Modified Free Inquiry Learning and Guided Inquiry Motodes on Students’ Physics Education that was categorized in average. Furthermore, the inferential statistics stated that t count > t table was 3,12 > 1,98 in which H0 was rejected. These showed that there was the difference in the understanding of extrapolation between Modified Free Inquiry Learning and Guided Inquiry Motodes on Students’ Physics Education, UIN Alauddin Makassar.
