Science generic skills of 'chemistry'? prospective teachers: A study on collaborative learning using Exe-media

Abstract

Collaborative learning is a learning model that guides students to gather ideas and data to solve common problems. In this study, collaborative learning was integrated with Exe-media on reaction rate and salt hydrolysis to improve prospective teacher generic science skills. Specifically, this study aims to investigate Exe-media effectiveness to improve prospective teacher generic science skill. This study employed methods of a quasi experiment with a nonequivalent control group design. The subject of this research are prospective teachers of class Kim'B as experiment class and Kim'C as control class of Department of Chemistry Education, Faculty of Mathematic and Natural Science, Universitas Negeri Medan. Experiment class received treatment in form of learning used collaborative learning using Exe-media. Control class received treatment in form of learning used conventional model using power point as media. Data was collected through pretest and posttest results from prospective teacher in both classes. A t-test was used and it is found that level of significance is 0.002 (sig. < 0.05) proving that collaborative learning using Exe-media is effective to improve prospective teachers' generic science skill.
