Abstract
This research is an experimental research that is able to find out whether there are differences in students' chemistry learning outcomes that teach with Problem Based Learning model (PBL) and Discovery Learning (DL) using Real Media Lab. In my experiments I was taught by PBL model with real lab and experiment II class with DL model using original lab. Data analysis uses two-t test. Expectation 1 class has an average pre and post test score of 51.5 + 7.27 and 77.12 + 8.90 with an average gain of 0.55. The experimental class II has a pre-test average of 43.1 + 6.65 and a post-test of 58.25 + 7.73 with an average gain of 0.26. Result of t test at α = 0,05 obtained tcount = 10,08> ttable = 2,0021 hence alternative hypothesis accepted, and concluded there are difference of learning result which significant between student taught by PBL model and DL model that is equal to 26%.
