PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING TERHADAP HASIL BELAJAR PADA MATERI IKATAN KIMIA DI SMA NEGERI 9 PALU

This study aims to determine the effect of Problem Based Learning model on learning outcomes in the Chemichal Bonding material at SMA Negeri 9 Palu. This type of research is a quasi-experimental design with pretest-posttest control group design. This research was conducted by making two groups namely class X MIA 1 as a control group (n = 28) and class XI MIA 2 as an experimental group (n = 28).Testing student learning outcomes data using the average value and Man-Whiteney U-test. The results of data analysis obtained the average value of the experimental class was 83.03 and the control class was 64.10. Based on the results of the Man-Whiteney U-Test test obtained Zcount (-5.666) <Ztable (-1.96), then Ho is rejected and Ha is accepted, so it can be concluded that the Problem Based Learning model on chemical bonding material has a positive effect on student learning outcomes at SMA Negeri 9 Palu.
