Abstract

This study aims to determine the effect of PBL on physics learning outcomes in light material at SMP Negeri 2 Tambusai. The method used in this study is a quasi-experimental method with the research population being class VIII students of SMP Negeri 2 Tambusai and the sample in this study was 50 students. The sampling technique used is purposive sampling. The experimental class (VIII1) research sample was obtained using the PBL model and the control class (VIII2) using the conventional model. The instrument used is a test of learning outcomes in the form of multiple-choice as many as 20 questions. before receiving treatment for the two samples, the experimental class pretest average score was 38.80 with a standard deviation of 13.87 and in the control class the average value was 38.20 and the standard deviation was 11.26. After doing different studies, the average posttest score for the experimental class was 71.00 and in the control class the average score was 65.80 and the standard deviation was 9.97. the results of the pretest and posttest data prerequisite test stated that the sample had normality and homogeneity distribution. then a one-sided t-test (α=0,05) and a simple regression test were performed. from the results of one-party t-test, namely thitung> ttabel (1,761 > 1,677) with a significant level of 0.042. and for the results of the simple regression test Y = 24,64+0,61X . in the equation the linear regression direction coefficient (b)=0.61 indicates that if student activity increases by 1, student learning outcomes will increase by 0.61. it is concluded that there is a significant effect of the PBL model on the learning outcomes of class VIII students of SMP Negeri 2 Tambusai in the academic year 2020/2021

Abstract

This study aims to determine the effect of using practicum tools with diferentiated learning strategies on student learning outcomes. The research method used is quasi-experimental design. The population in this study was all of class X MIA, totaling 212 students, of SMA Negeri 8 Medan. The research sampling technique is purposive sampling technique. Non-equivalent control group design is the type of the research design. The sample in the study consisted of an experimental class, namely class X MIA 6, and a control class, namely class X MIA 5. The experimental class was treated with differentiated learning strategies, while the control class was treated with conventional learning. The research instruments used were multiple-choice questions and student observation sheets. The average score of the posttest for the experimental class was 76.28 with a standard deviation of 6.9, and that of the control class was 72.08 with a standard deviation of 6.7. The pretest and posttest data obtained have been analyzed and met the prerequisites for testing the hypothesis, namely, the data is normally distributed and is homogeneous. The result of the right-tailed t-test on the hypothesis obtained the value of tcount > ttable, namely 2.608 > 2.002 whit = 0.05. Based on the testing criteria, the accepted hypothesis is H, which means that there is an effect of the treatment that is the use of practicum tool with different learning strategies on student learning outcomes at SMA Negeri 8 Medan for the 2022/2023 academic year. The result of the simple linear regression equation is Y = 65.9 + 0.34X.
