EFFECTIVENESS OF STUDENTS ACTIVITY WORKSHEET BASED ON CONTEXTUAL TEACHING AND LEARNING TO IMPROVE STUDENT’S ABILITY IN CONCEPT UNDERSTANDING

Abstract

Abstract

This study aims to analyze the effectiveness of Student Activity Workheets to improve students’ ability in concept understanding in the Earth Layer Material. This research was conducted using One Group Pre-test and Post-test Design. The developed worksheet consists of three sub-layers of the earths layers, namely the atmosphere, lithosphere, and hydrosphere. The results of effectiveness Student Activity Workheets in improving student’s understanding ability can be seen through increasing student n-gain and n-gain cognitive processes of understanding ability used. The results showed that 22 students obtained n-gain in the highest category and 9 students obtained n-gain in the low category. There are five cognitive processes of the understanding ability got n-gain with a high category, namely interpretation, exemplifying, classifying, summarizing, and comparing. The two cognitive processes of understanding ability got n-gain with the moderate category are inference and explanation. Based on the results of the study it can be concluded that Student Activity Worksheets (LKS) based on Contextual Teaching and Learning was effective to improve students’ ability in concept understanding in the Earth Layer Material.
