THE EFFECT OF PROCESS ORIENTED GUIDED INQUIRY LEARNING MODEL ON STUDENT LEARNING OUTCOMES IN CLASS XI MATERIALS

Abstract

This research was motivated by the difficulties students face in understanding the material on cells. Specifically, 70% of the students' learning outcomes in cell material did not meet the Minimum Completeness Criteria, indicating a need for improvement in the learning process. To address this, innovative learning models were implemented. The study utilized a quasi-experimental design with a pretest and posttest control group design. The research sample was selected using purposive sampling techniques, resulting in two classes: Class XI MIPA 5 (Experimental Class) where the POGIL learning model was applied, and Class XI MIPA 6 (Control Class) where the conventional learning model was used. Data collection involved administering a test consisting of 20 multiple-choice questions. The mean scores for the control class were 37.91 and 67.63. Data analysis was conducted using the Paired Sample t-Test with SPSS Version 21 software. The results of the hypothesis testing revealed that the POGIL learning model had a significant effect on student learning outcomes in cell material for Class XI MIPA SMA N 12 Medan T.P. 2022/2023. The N-gain value for the experimental class was 0.71, falling within the high category, while the control class had an N-gain value of 0.46, categorizing it as medium. This indicates that the POGIL learning model had a greater impact on student learning outcomes in cell material for Class XI MIPA SMA N 12 Medan T.P. 2022/2023.
