This type of research is quasi experimental research with posttest only control group design research design. The population of this study is all class XI IPA of MAN 2 Bengkulu City academic year 2018/2019 as many 133 students. The analysis of the data was used the normality test,  homogeneity test, and hypothesis test.  The research sample was taken by purposive sampling technique. Data on the results of students' critical thinking skills are obtained from the value of the posttest or final test. Posttest is done by using test instruments in the form of descriptive tests as many as 6 items, each of which has a different critical thinking indicator. Previous test instruments were tested and analyzed to see the level of validity, reliability, differentiation and the level of difficulty of the questions. The results of the study showed that the average value of students' critical thinking ability achievement in the experimental class 1 was higher than that of the experimental class 2 students which were 74.09 and 70.22. Based on these results, the experimental class 1 which applied the problem solving learning model was better at improving students' thinking skills than the experimental class 2 which applied a problem-based learning model. Hypothesis testing with the T-test at the 0.05 significance level yields a sig value. (2-tailed)> level of signicant which is 0.147> 0.05 so that Ho is accepted. Thus, it can be concluded that there is no significant difference between the critical thinking skills of the experimental class 1 students who apply PS models and experimental class 2 students who apply the PBL model.

The current study explores the effects of applying the Problem-Based Learning (PBL) Strategy on the 11th-grade scientific stream Jordanian students&#39; acquisition of the concepts of developing their critical thinking skills. This study&#39;s significance lies in its emphasis on the worldwide growing tendency to apply PBL teaching strategies that consider developing the students&#39; mental capabilities and creative thinking skills and, consequently, help them solve status-de- facto educational problems face and solve problems in their lives. The researchers used the experimental method in their study, which is based on studying the relationship between the independent and the dependent variables. For this reason, three study student groups, equal in their age, intelligence, academic achievement, social and economic standing, were selected. Two experimental groups were exposed to the independent variable (PBL) method, whereas the third control group was not exposed to the independent variable. Instead, it was taught in the Motion Unit in Physics by using the traditional teaching method. The results of the study were analyzed statistically, applying for the SPSS program. The Arithmetic Mean, the Standard Deviation, the Torsional Modulus, and the T-Test were used for the study analysis. The study results revealed that the two (PBL) experimental groups have proved to be much more superior to the control group&#39;s third traditional teaching method.

The Impact

The application of problem based learning in the classroom often experiences obstacles, primarily to teach high-level thinking skills, such as critical thinking skills. To overcome these obstacles, in this study we tried the use of peer tutors to guide their friends in a collaborative group when solving problems. This study aims to describe the impact of peer tutoring in problem-based learning on the critical thinking skills of high school physics students. This type of research is a quasi-experimental study with a pretest-posttest control group design. The sample of this research is class X MIPA 3 and X MIPA 4 SMAN 4 Jember. One class was given treatment using problem-based learning accompanied by peer tutoring, while one other class only used problem-based learning. Data about critical thinking skills were obtained from the posttest at the end of learning which was then analyzed using the Independent Sample T-test on SPSS 23. The statistical test results stated that there were differences between the average values of the experimental class and the control class. Thus, it is concluded that peer tutoring in the problem-based learning model has a significant effect on critical thinking skills. The essential aspect of thinking skills with the highest value lies in interpreting skills.
