Critical thinking skills are one of the four main competencies that must be empowered in the 21st-century learning. This study aimed to describe students' critical thinking skills through the application of blended-problem-based learning (PBL) in the Cell Biology course. The data sources of this research were 28 students who were taking Cell Biology Course in Department of Biology Education, Universitas PGRI Madiun. The research instruments used were 1) observation sheet, 2) interview guidelines, and 3) critical thinking skills test. The study was designed by applying blended-PBL on 12 topics. The data analysis was performed in descriptive qualitative. The results showed that the application of blended-PBL was able to train students to improve their critical thinking skills in term of how to answer the test given. However, further studies need to be done with a wider number of samples and material scope to get more comprehensive information.

Solution material is one of the materials that requires a student's level of understanding at the critical thinking level. Critical thinking skills train students to learn to find and solve problems using scientific methods based on real experiences encountered and experienced directly. To be able to find the concept of knowledge based on existing realities, an appropriate learning model is needed, namely a problem-based learning model. This study aims to determine students' critical thinking skills. The type and design of this research is development research with a nonequivalent control group design. The samples of this research were students of semester 2, Biology Education Study Program, University of Flores. This research was conducted from April-June 2020. Data were collected using the critical thinking ability test technique of students in the chemical solution subject, followed by processing and analyzing data using the prerequisite analysis test in the form of normality test, homogeneity test, and t-test. The data analysis shows the significance value of the normality and homogeneity test, namely α> 0.05, while for the t-test α <0.05. From these results prove that problem-based learning can improve students' critical thinking skills in chemistry subject matter solution

The problem at SMK Dwijendra Denpasar in PPKn is that students are less active in critical thinking and less active in expressing opinions. The success in PPKn learning lies in the use of the learning model. The problem-based learning model has specifications that can train students to actively think critically in solving problems, and dare to express opinions. The purpose of this research is to determine the application of problem-based learning models to improve students 'critical thinking skills in PPKn subjects and to find out the obstacles in applying problem- based learning models to improve students' critical thinking skills in PPKn subjects. This research uses descriptive qualitative method. The research location is at SMK Dwijendra Denpasar. Observation data collection techniques, and documentation. Data analysis was performed using an interactive data analysis model that was carried out through the process of data reduction, data presentation, and drawing conclusions / verification. The results of the study showed that the application of problem-based learning model based on problems to improve students' critical thinking skills in Pancasila and civics education subjects had been implemented in accordance with the learning implementation plan. The application of problem-based learning models to improve students 'critical thinking skills improves students' critical thinking skills, increases student learning activities, and increases responsibility attitudes. Obstacles in the application of the based learning model are less learning time, less education to be a good facilitator at the group guidance stage, and to students who are less active in group discussions. The suggestion that can be given is that the school needs to conduct socialization so that it is more optimal for the application of problem-based learning models, for teachers to be more able to increase creativity in the use of learning models, to be more efficient in the time available during the teaching and learning process, as well as during the learning process. actively guiding students in group discussions.

Observation Results

Critical thinking should be given to students as they age in the 21st century. The continued impact of perception shows that there are still many students who do not have the option to overcome their thinking, speaking, and logic skills. Observation results show that many students have not been able to utilize their intellectual ability to think critically. Furthermore, the evaluation questions that have been given by the teacher are not analyticalin nature, resulting in not triggering students to think critically. Problem Based Learning (PBL) is a model of learning that is suitable for stimulatingstudents' critical thinking. The purpose of this research that produces the E-module -based PBL valid, p practical and i effective. Type researchis development research. The Plomp model is the applied model. The results of the study resulted in the level of validity of the PBL -based E-module which was 89.10% (very valid). The results of the practicality level of teachers are 94.17% (very practical) and the level of practicality by students is 86.47% (very practical). The results of the PBL -based E-module effectiveness test show that the PBL -based E-module is very effective. Thus, the conclusion is that the PBL -based E-module that has been developed is very valid, very practical, and very effective.

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.
