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.

This study aims to analyze the effect of using an E-module with a wetland environment-based PBL model on students' critical thinking skills and environmental care attitudes. This study was a quasi-experimental study with a non-equivalent posttest only control group design. The study population was 150 students, while the sample was selected by random sampling. The number of samples in this study was 64 students who were divided into two classes. The instrument used was a test, namely a question of critical thinking skills in the form of an essay and a non-test in the form of a questionnaire for environmental care attitudes. The collected data were analyzed by using Multivariate Analysis of Variance. The results showed that the significance of the three hypotheses was 0.000, which means less than 0.05 (0,000 <0.05). So, it can be concluded that there is a positive effect of using the E-module with the PBL model on critical thinking skills and environmental care attitudes. The novelty of this study integrates the wetland environment in the learning process using teaching materials in the form of E-modules in the learning process of the topic of acid-base solutions on critical thinking skills and environmental care attitudes of students

The learning process at SMAN 1 Kluet Utara and SMAN 1 Kluet Selatan, does not appear to have developed critical thinking skills of students, this is because learning does not provide opportunities for students to identify problems and conclude new ideas or a observational act. The process of learning biology in schools does not encourage students to think critically. The research objective was to analyze the improvement of critical thinking skills by using the discovery learning model combined with constructivism-based modulesin on the excretory system concept. The method used was a quasi-experimental, pretest posttest design non-equivalent control group design. The population in this study were 156 students of class 11th MIPA who came from two schools, while the sample was 104 taken by purposive sampling.The instrument used was a reasoned multiple choice question accompanied by a rubric. The data analysis used was n-gain and independent sample t-test. The results showed that the critical thinking skills obtained was 0.78, with an increase in class critical thinking skills including the high category. This shows that there are differences in the critical thinking skills of students between the experimental class and the control class on excretory system concept in class 11thSMAN 1 Kluet Utara and SMAN 1 Kluet Selatan. Thus, the implementation of discovery learning model combined with constructivism-based modulescan improve students' critical thinking skills on excretory system concept.
