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 ttable = 1.9954. Furthermore, by comparing the value of ttable with tcount obtained that tcount > ttable namely 5.4265 > 1.9954. This means H0 rejected and Ha 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.

This research have purpose to know the effect of problem based learning model on student’s learning outcomes and student’s learning activity on geometry optic topic. This research is a quasi experiment using control group pre-test-post-test design. The sampel of theses research consisted of two classes, each contains 30 students. By using total sampling, one class is made as experiment class that uses problem based learning model, and one class is as control that uses conventional learning model, so class XI science -1 as control class and class XI science -2 as experiment class. The instrument used was a test of learning outcomes in the form of students learning outcomes in the form of 7 essay test. In the experimental class the average activity of students in the three meeting, are 62.44, 70.67 and 77.78. The learning activity have increase during three times meeting and have average value 70.33 and have good category. The data obtain so problem based learning model can increase learning activity on geometry optic topic of SMA Negeri 2 Lintongnihuta class XI science second semester A.Y. 2017/2018. The value of the average post-test experimental class was 75.13 and control class was 67.10.

Encountered problem at school under research is student”s low ability in physics problem solving and low responsibility in completing assignment. The objectives of this research are to know:(1) the effect of character education implementation in improving students responsibility using problem solving strategy, (2) the effect of character education implementation in improving student’s problem solving competency of physics problem. The research method was quasi experimental, using one experimental with the implementation of problem solving strategy with character education, and one control class with problem solving strategy without character education. Students responsibility data was obtained by direct observation using observation sheet and psychology test, and physics problem-solving competency was obtained using essay test. The data was analyzed using chi-square. These results indicate that implementation of character education give effect to the improvement of students responsibility and student’s problem-solving competency of experimental class is also better than students of control class.Key words: character education, physics, problem solving strategy, responsibility
