Improving Critical Thinking Ability through Discovery Learning Model Based on Patiayam Site Ethnoscience

Abstract

This study aims to determine the improvement of critical thinking ability toward grade IV elementary school student using Discovery Learning model based on Patiayam site ethnoscience. This research type is Quasy Experimental Design with the form of non-equivalent control group design. The sampling technique used is the type of Cluster Randong Sampling. The result of n-gain analysis show that the control class gets average 0,2535 as low category, while the experiment class gets average 0,5574 as medium category. The result of Independent Sample t-test show result of critical thinking ability on the observing with the result of Sig. (2-tailed) of 0,000 < 0,05. The conclusions of this study are the result of the critical thinking ability of the experimental group are higher than result of the control group.
