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.

Abstract. The purpose of this study was to determine the effectiveness of the problem-based learning model based on ethnoscience on students' critical thinking skills on colloidal material. Experiments were conducted on a sample of 36 experimental class students with an ethnoscience-based problem-based learning model and 36 experimental class students with a convention learning model. This research method is a quasi-experimental design with a nonequivalent control group design. The instruments used are essay tests and observation sheets. The results of this study indicate that the average posttest in the experimental class is 76.08, which is higher than the control class, which is 69.33. These results indicate that the use of ethnoscience-based learning problem-based learning models on colloidal material is effective in improving students' critical thinking skills compared to using conventional models.

Abstract-this study aims to know, analyze and evaluate the differences of students’ critical thinking skills by using problem based learning model and conventional models. This study uses a quasi-experimental method with quantitative approach using Nonequivalent (Pretest-Posttest) Control-Group Design. The data collection technique used in this study is using the test. The data analysis technique is done by independent t-test sample. Moreover, this research shows the significant differences if seen from the average of percentage of  experiment class; pretest is less while posttest is so gratified. The result of pretest control class is less and posttest is enough The results of this research give the recommendation for teachers and next researchers to apply problem based learning model to enhance critical thinking ability of students. In addition, problem based learning model is also expected to encourage students to be able to solve problems encountered in everyday life, especially in social studies.Keywords: Problem based learning, conventional learning model and critical thinking.

The research method used quasi-experimental with matching-only posttest-only control group design which implemented in one of the Junior High School of Yogyakarta. The instrument used is a valid test instrument namely posttest with descriptive evaluation. The result of this research showed that there is a difference of mathematical critical thinking skills between students who obtain mathematics learning using PBL model and students who obtain mathematics learning using guided inquiry model. Furthermore, the average of mathematical critical thinking skills between a student who obtains mathematics learning using problem based learning model is higher than students who obtain mathematics learning using guided inquiry model.

One of the factors lead to the low critical thingking skill is the implementation of teacher center learning. The purpose of this research was to determine the effect of the implementation of Problem-based Learning integrated with Cooperative Script to students’ critical thinking skills. This quasi-experimental research was done in senior high schools of Samarinda, Indonesia. The design used in this research was nonequivalent pretest - posttest control group design. The sample was the class XI  students of natural science. The treatment was done in the odd semester in 2016/2017 academic year. The data analysis used was independent-samples t-test (α = 0.05). The results of the data analysis showed that the tvalue (16.57) > ttable (2.00). The mean value of students’ critical thinking skills in the experimental group was 77.28 which means 62% higher than those who were in the control group (47.60). Thus, it can be concluded that the implementation of Problem-based Learning integrated with Cooperative Script gives the significant effect to the students' critical thinking skills.

Students in society 5.0 era education are directed to have adaptive and reactive response patterns to change through effective synergy as domain systems inaccessibility to technology in developing their skills actively and independently through critical thinking skills. Critical thinking skills as a cognitive domain in identifying, analyzing, and thinking of practical and creative ways to solve problems are needed to develop in the era of global society 5.0. Therefore, teachers are required to design learning processes that can accommodate student competencies in the era of society 5.0, one of which is the implementation of the innovative Interactive Blended Problem-Based Learning (IBPBL) learning model. This study aims to determine the effect of Interactive Blended Problem-Based Learning (IBPBL) assisted by Virtual Classroom on students' critical thinking skills. This type of research is a quasi-experimental study using a posttest-only control group design. The sample in this study used 72 students in class X IPS 2 (n = 36 control class) and X IPS 3 (n = 36 experimental class), Specializing in Social Sciences, SMAN 1 Tempeh, Lumajang Regency, East Java. The data analysis technique used the independent t-test hypothesis test to determine the significance value of the difference in the average treatment given to both the control and experimental classes. The results showed an effect of Interactive Blended Problem-Based Learning (IBPBL) assisted by Virtual Classroom on the critical thinking skills of students with Sig. (2-tailed) 0.000.

This study aimed to determine the effect of learning based on learning problems on students' critical thinking skills in plant biotechnology materials. This research is a quasi-experimental type using the design of "Post test and pretest, Non Equivalent Control Group Design" which consists of two experimental classes. The first experimental class used the Problem Based Learning learning model and the second class used a discussion learning model. Problem-based learning motivates students to learn independently to find information themselves from various sources, such as the environment, media and the internet. This learning trains students to think critically about contextual problems related to the material so as to improve students' cognitive abilities ranging from identifying problems, formulating hypotheses, analyzing problems, evaluating and concluding.
