Problem Based Learning Model, Acid Base Titration Material, and Learning OutcomesAbstract
The goal of this study was to describe how the Problem Based Learning approach improved students' learning outcomes on acid-base titration material in class XI SMA Negeri 5 Palu. Simple Random Sampling was used to sample the sample for this study, which consisted of two classes, class XI MIPA 2 as replication class I (31 students) and class XI MIPA 4 as replication class II (30 students). The N-gain test was used to assess the research data from the two classes. The average N-gain value of 0.79 was included in the high category for replication class I, and the average N-gain value of 0.73 was included in the high category for replication class II. According to the data analysis, the average pretest and posttest values for replication class I were 25.32 and 84.52, respectively, with a 59.2 increase in learning outcomes. While replication class II were 28 and 81, respectively, with a 53 increase in learning outcomes. As a result, it can be concluded that using the Problem Based Learning model in class XI MIPA on acid-base titration material at SMA Negeri 5 Palu can inmpove student learning outcomes.
