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

<p><em>The purpose of the study was to determine the role of problem-based learning model to critical thinking ability and creative thinking ability. The subjects were students of semester IV Mathematics Education Study Program, University of Indraprasta PGRI, Jakarta in 2013/2014, in the subject of Basic Chemistry II. The selection of the class for this study was based on multistage random sampling. Experiments conducted on the sample of 30 experimental class students with problem-based learning model and 30 control class students with expository learning model. The data was collected by implementing tests of critical thinking ability and creative thinking ability with essay test. Analysis of research data using MANOVA support by SPSS. From the results of the study concluded that learning models give influence to the critical thinking ability and creative thinking ability together (F=21,815;p=0.000).</em></p>

Implementation of Curriculum 2013 requires students to learn actively, independently, and critical thinking. Critical thinking is an activity through thinking about ideas related to concepts or problems. The efforts to improve critical thinking skills of learners can be done by using the appropriate learning model. One of the learning models that can be used to improve the ability of critical thinking is a problem-based learning model. This type of research is quasi experiment with randomized control-group pretest posttest design. The sample of this research choosed by used purposive sampling method. Class VIII6 as experimental class and class VIII4 as control class. Data of this research result are quantitative data of critical thinking ability. Data were analyzed by using t test. The results showed that the mean difference of posttest value with pretest value of critical thinking ability of experimental class learners is higher than control class. Hypothesis testing with t-test obtained tcalculate=2,94>ttable= 1,67, then H1 accepted. Based on these results the authors conclude that the implementation of problem-based learning model has a positive effect on the ability to think critically learners on the material additives and addictive substances.

[Title: The Effect of Thinking Aloud Pair Problem Solving Learning Model Toward Student Physics Science Learning Outcomes]. This research aims to know the effectiveness of the learning problem based learning model assisted work sheet for the critical thinking ability of physics students of grade X SMAN 1 Lingsar inacademics year 2016/2017. This was an experiments research that using design research Posttest-Only Control group Design. The population in this research were the whole grade X SMA Negeri 1 Lingsar in academics year 2016/2017. Sampling taken with using cluster random sampling technique with the students of class X. MIA. A as experiments class and grade X. MIA. D as controls class. Research hypothesis was analysis with the t-test for one party (the party right). Based on the hypothesis test results obtained tcount> ttable at significance level of 5%, then it can be inferred that the model of learning problem based learning assisted work sheet effective for critical thinking ability of physics students SMAN 1 Lingsar.

The aims of this study to determine the improvement of students' critical thinking skills through the application of learning model the Problem Based Learning in Biology subjects in class X SMA Negeri 1 Kluet Tengah. The subjects in this study were students of class X SMA Negeri 1 Kluet Tengah, with total of 31 students, with focus of this research critical thinking skills ability in Biology subjects. The research design used was classroom action research, which was conducted in two cycles. Each cycle consists of four stages, namely: planning, implementing, observing, and reflecting. In the pre-cycle, the students 'critical thinking ability was 37.81% in the less critical category, since implementation of the first cycle the students' critical thinking ability became 51.80% with the fairly critical category. In cycle II, the average achievement of students' critical thinking skills has increased to 76.90% in the critical category. Thus the results of this study indicate that the application of learning model the Problem Based Learning can improve students' critical thinking skills in Biology subjects in Class X SMA Negeri 1 Kluet Tengah.

The Subject

This study aimed to analyze and describe instructions applying problem-based learning in school. The research design is a systematic literature review conducted in seven steps. Data searched and retrieved from google scholar. Eligibility criteria for selected studies are articles published between 2017-2021 and written in the Indonesian language. This study concluded that applying problem-based learning in instruction positively affects learning outcomes, especially problem solving and critical thinking ability. PBL steps commonly used in classrooms are the teacher planning the lesson, stating the learning objectives, explaining the subject matter, dividing the group, students carrying out investigations, the teacher providing feedback. These steps are more of a learning activity than a sequence of learning activities.
