Abstract

This study aims to determine students' frequency, evaluation, and perceptions on the implementation of practicum in SMA Negeri in Rantauprapat City. The sample in this study were 3 teachers and students of class X MIA at SMA Negeri 1 Rantau Utara, SMA Negeri 2 Rantau Utara and SMA Negeri 1 Rantau Selatan totaling 107 people taken by random sampling. The data analysis technique used is a quantitative descriptive analysis technique, which describes and explains the data based on the field. This research is an explorative survey, namely by observing, interviewing, and exploring. The analysis results show that the average frequency of practicum implementation is 66%, which is quite often done. The laboratory conditions in the three sample schools were classified as very good (83.18%). The student interest in laboratory activities is also classified as very good (86.14%), but some schools, namely SMA Negeri 1 Rantau Utara and SMA Negeri 2 Rantau Utara, experienced problems in the time of practicum implementation (70.44%). The preparation and implementation of the practicum have been carried out very well (88.07%), with 83.90% of reports and evaluations carried out for each practicum activity. However, although it is classified as very good, the average evaluation value is only 59.60, which is quite enough.

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.
