<![CDATA[The study is experiment research (quasi experiment), which aims at analyzing the differences of critical thinking skill and learning outcomes taught by utilizing Problem-Based Learning and direct learning. The research design employed non-equivalent pretest-posttest control group design. The results of descrective analysis obtained the mean score of critical thinking skill and learning outcomes in experiment class 1 is 77.60, and experiment class 2, 75.36 with each standard of deviation 6.92 and 9.06. The mean percentage of critical thinking skill indicator in experiment class 1 is 83.14 and in experiment class 2 is 78.01. The mean score of learning outcomes taught by utilizing PBM model is higher than the direct learning model. The result of hypothesis test with t=test at the significant level α = 0.05 obtained significance (0.001 < 0.05), indicate that the hypothesis is accepted. The conclusion of the study is there ia a difference of critical thinking skill and learning outcomes of grade XI MIPA at SMAN 15 Makassar taught by utilizing problem based learning model and direct learning on Hydrocarbon Compounds subject.]]>
