Impact of Implementing Problem Based Learning with Interactional Methods on Middle School Students’ Problem Solving Skills

This study aims to determine the impact of implementing the PBL (Problem-Based Learning) model with an interactional method on problem-solving skills in a junior high school in Bangil district. The research used a one-group pretest-posttest design with random sampling. Three classes received the same treatment, namely the PBL model with an interactional method. The problem-solving test was based on Polya's indicators: understanding the problem, planning a solution strategy, implementing the strategy, and evaluation. Data analysis used inferential statistics. The results showed that the ANOVA test yielded a Sig value of 0.022 < 0.05, indicating differences between groups. The PBL model with the interactional method significantly influenced students' problem-solving skills, as evidenced by significant results in two groups (VII-J and VII-K), while the other group (VII-G) showed lower results.
