Implementation of PBL (problem-based learning) to improve interdisciplinary thinking skills and biology learning outcomes

This study aims to analyze the application of the PBL model that can improve interdisciplinary thinking skills and biology learning outcomes for students of class XI MIPA 7 SMA Negeri 1 Malang. The research method used is classroom action research, using mixed-method concurrent nested (embedded) research. This study involved 31 students of class XI MIPA 7 at SMA Negeri 1 Malang. The pretest and posttest instruments are in the form of multiple-choice questions for interdisciplinary thinking skills with an N-Gain score of 0.7121 with high criteria. Affective learning outcomes show an average of 97.4% classical completeness. Cognitive learning results show that the average classical completeness is 86.6%. The results of psychomotor learning showed average classical completeness of 96.8%. Based on the study results, it can be concluded that the application of the PBL model can improve interdisciplinary thinking skills and student biology learning outcomes in the affective, cognitive, and psychomotor domains.
