Effect of Problem Based Laerning Model on Salt Hydrolysis Lessons about the Students’s Learning Outcomes in SMAN 1 Ranah Pesisir

Abstract

Presentation on the topic of Salt Hydrolysis can be started from a real problem, using the Problem Based Learning (PBL) model. The PBL model should be able to increase student’s' curiosity to get concepts independently. The purpose of this study was to determine the effect of PBL model on salt hydrolysis lessons about the student’s learning outcomes in SMAN 1 Ranah Pesisir. This research is quasi experiment with nonequivalent groups post-test only design. Data are normal and homogeneous, as of hypothesis testing uses t-test is done at α 0.05, obtained t count 5,2 and t table 2,67. The shows the learning outcomes on salt hydrolysis lessons between classes using PBL model are higher than conventional model in SMAN 1 Ranah Pesisir.
