THE EFFECT OF COOPERATIVE LEARNING MODEL TYPE OF GROUP INVESTIGATION ASSISTED BY PHET SIMULATION ON STUDENT LEARNING OUTCOMES AT SMA NEGERI 1 BAHOROK

Abstract

The purpose of this study was to find out whether the investigative group-type cooperative learning model assisted by PhET simulations can improve student learning outcomes at SMA Negeri 1 Bahorok. The research method used is quantitative research designquasi experiment two group pretest-posttest. The population in this study was class XI IPA at SMA Negeri 1 Bahorok and the sample used was class XI IPA 1 with a total of 36 students as the experimental class and XI IPA 2 with a total of 34 students as the control class. Data collection was carried out by using questions onpretest andposttest. The results showed that the average valuepretest in the experimental and control classes of 50.0 respectively9 and 43.06 while the average valueposttest obtained in the experimental and control classes of 73.5 and 59,24. Based on one-party hypothesis testing to find out differences in student learning outcomes that have been carried out, it is found that the value of t_table = 1.9954. Furthermore, by comparing the value of t_table with t_count obtained that t_count > t_table namely 5.4265 > 1.9954. This means H₀ rejected and H_a accepted which states that "There is an influence from the cooperative learning model of the Simulation-assisted Investigation Group typePhET on the material Elasticity and Hooke's Law on student learning outcomes.
