. Perbandingan Hasil Belajar Kimia antara Model Pembelajaran Problem Based Learning dan Discovery Learning pada Materi Larutan Penyangga SMA Negeri 7 Tawaeli

This study was conducted to determine the comparison of student learning outcomes in class XI science using the Discovery Learning with Problem Based Learning on the buffer solution material at SMA Negeri 7 Tawaeli. This type of research is a quasi-experimental or quasi-experimental research design withposttest only. The population in this study were all students of class XI IPA SMA Negeri 7 Tawaeli who were registered in the 2021-2022 academic year as many as 50 people. The sampling technique in this study used a purposive sampling method. The samples in this study were 25 students in class XI IPA 2 and 25 students in XI IPA 3. Testing the research data using the Ujimann Whitney program SPSS 25.0 analysis where the experiment using the problem based learning obtained an average rating of 32.64 while the experimental class using the discovery learning was 18.36. Based on the test results, it is concluded that between discovery learning and problem based learning there are differences in learning outcomes, namely the problem based learning model is superior to the discovery learning model.Then the hypothesis H0 rejected and H1is accepted, namely H1: 1 . 2: there is a comparison of chemistry learning outcomes between classes usingdiscovery learning and classes usingproblem based learning in class XI SMA Negeri 7 Tawaeli
