Abstract

The research conducted in the even semester of the 2021/2022 academic year aims to see how the influence of different learning strategies on the learning results of eighth-grade students of State Junior High School 4 Medan on vibration and wave material. This study used true experimental research with a pretest posttest control group design. The population used in this study was class VIII of State Junior High School 4 Medan as a whole consisting of 346 people. The sample of this study was class VIII-2 as the experimental class and VIII-3 as the control class selected using the cluster random sampling technique. To find out student learning results, multiple-choice questions with a total of 20 items have been previously tested for validity, reliability, difficulty, and discrimination. The learning results of the two classes were tested for normality with the Lilliefors test and the homogeneity test using the F test. Then a one-sided t-test was carried out for = 0.05, obtained tcount = 2.07 > ttable = 1.6697. As for the regression test obtained = 15.79 + 0.78X. Based on the results of the study, it can be concluded that there is an influence of differentiation learning strategies on the learning results of grade VIII students of State Junior High School 4 Medan.

Abstract

This study aims to determine the effect of the Teams Games Tournament (TGT) cooperative learning model on students' physics learning outcomes regarding the topic of Quantities and Units at SMA Negeri 8 Medan. The study employed a quantitative method using a quasi-experimental approach with a pretest-posttest control group design. The research sample consisted of class X-3 as the experimental group and class X-4 as the control group, with 30 students in each class. Data were collected via pretests and posttests and subsequently analyzed using normality, homogeneity, and t-tests. The results showed that the average pretest scores were 48.83 for the experimental group and 48.67 for the control group; with tcalculated (0.040) < ttable (2.002), there was no significant difference in initial ability. The average posttest scores were 80.33 for the experimental group and 66.00 for the control group. The t-test results showed tcalculated (4.464) > ttable (1.671), leading to the rejection of H0 and the acceptance of Ha. Thus, the Teams Games Tournament (TGT) cooperative learning model has a significant effect on students' physics learning outcomes regarding the topic of Quantities and Units.
