Inovasi Pembelajaran Berbasis Masalah Berbantuan Media Transvisi untuk Meningkatkan Keterampilan Proses Sains

This study aims to design problem based learning with transvisi media. The learning was applied to improve science process skills at electrolyte-nonelectrolyte material and concepts redox. Quasi experiment design with pretest-posttest control group was used. The differences between pre and post test of Science Process Skill was assumed as effect of treatment. Research subjects were two classgroup of X class in SMA N 1 Randublatung. One class was as control group and the other was as experiment group. They were determined through cluster random sampling. Science process skill was measured by multiple choice test-with reason. Data were analyzed by t-test. Results showed that the implementation of problem based learning at electrolyte-nonelectrolyte and redox can improve students\u27 science process skills, as well as students gave positive responce to learning implementation
