EFFECTIVENESS OF IMPLEMENTING PROJECT LEARNING MODELS BASED LEARNING THROUGH MAKING SIMPLE SOLAR POWER PLANTS ON LEARNING OUTCOMES

Abstract

The purpose of this study is to determine learning outcomes before and after the application of the Project Based Learning (PjBL) learning model through the manufacture of simple solar power plants, find out the differences in learning outcomes before and after the application of the Project Based Learning (PjBL) learning model through making simple solar power plants, and find out the level of effectiveness of the Project Based Learning (PjBL) learning model through making solar power plants. Surya is simple in improving the learning outcomes of students in grade XII Science 1 SMAN 2 Jeneponto. The type of research carried out is a pre-experiment with a one-group pretest-posttest design research design. The population and sample of this study were students of grade XII Science 1 SMAN 2 Jeneponto, with a population of 144 students and a sample of 30 students. The sampling technique used is purposive sampling. The research instruments used are multiple-choice test questions (pre-test and post-test), model implementation observation sheets, and student observation sheets. The data analysis techniques used in this study are descriptive analysis, inferential analysis, and N-Gain analysis. The results of the descriptive analysis showed that the average learning outcomes of students before being taught with the PjBL (project-based learning) learning model were 33,666, which were classified as less, while after being taught with the PjBL (project-based learning) learning model, they were 75,333, which were classified as sufficient categories. For hypothesis test analysis using the Paired Sample t-Test test, a Sig. (2-tailed) value = 0.001<0.05 was obtained, meaning that there were differences in student learning outcomes before and after treatment was given in the form of applying the Project Based Learning (PjBL) learning model through making simple solar power plant teaching aids for grade XII Science 1 SMAN 2 Jeneponto students. Based on the results of the N-gain test, a score of 58.39% was obtained, which means that the application of the Project Based Learning (PjBL) learning model through making simple solar power plant props is effective enough to improve the learning outcomes of grade XII Science 1 SMAN 2 Jeneponto students for the 2022-2023 academic year.
