Students’ worksheet development on salt hydrolysis material through Problem-Based Learning to improve science process skill

Abstract

This research aims to improve science process skill within the topic of Salt Hydrolysis and to indicate students’ responses upon the implementation. This is an R&D research conducted at a High School in Banda Aceh. The data obtained were analyzed using several techniques, including feasibility test, student science process skill test, and responses of both students and teachers. The result showed that the product was a very feasible category by an average percentage of 93.75%. Limited trial to chemistry teachers at research school exhibited a similar category with an average percentage of 88.17%. For the final result, the comprehensive test was conducted by chemistry teachers among MA/MAS in Banda Aceh expressing the same category with an average percentage of 85.58%. The dissemination and implementation of developing SW for students of MAN Banda Aceh 1 obtained a very good percentage of 86.04% for science process skill. Besides, it showed both students and teachers have positive responses toward the implementation of this technique with an average percentage of 88.50% and 83.33%, respectively. Therefore, it can be concluded that the SW is feasible to be used for practical study on Salt Hydrolysis topic.
