This study aims to improve students' critical thinking skills through the application of the Problem Based Learning model to students. This model, if applied properly, can train students in solving contextual problems. The purpose of this research is to improve the critical thinking skills of students in class IXH MTs Darul A'Mal Metro City through the application of the Problem Based Learning model on population and environmental materials. classroom action research) using the Kemmis and Mc Taggart model where each cycle consists of planning (planning), implementation (action) and observation (observe), and reflection (reflect). The researcher acts as the designer of the action as well as the executor of the action, while the partner teacher acts as an observer. The research was conducted at MTs Darul A'Mal Metro in August-September. The research subjects were students of class IXH, totaling 24 male students. Data collection techniques used critical thinking ability observation sheets, critical thinking learning outcomes tests, field notes, and documentation. Data analysis was carried out by analyzing qualitative data consisting of data reduction, data presentation, verification and drawing conclusions. The research action is said to be successful if it reaches the predetermined success criteria of 75%. The results of the study based on observations showed critical thinking skills in the first cycle reached 57.80%, while in the second cycle it reached 79.38%, which means an increase of 21.58%.

The background of this research is, there is no learning model that can optimally support critical thinking skills, so it takes an innovative learning model. In this case, the researchers used web helped to guide discovery learning model to improve the critical thinking skills of the student in class X SMAN 4 Praya in academic year 2019/2020. This study aimed to find an effect of web assisted guided discovery learning on trigonometry material to critical thinking ability of the student in class X SMAN 4 Praya in academic year 2019/2020. This study use a quantitative research approach to the type of experimental research. In this experiment the researchers used a quasi-experimental, and uses two classes as a research, the experimental class and control class. The population of this research is all the student in class X SMAN 4 Praya and and choose two class as a sample class that is X MIPA 5 as a experimental class and X MIPA 3 as control class. Student in experimental class used web assisted guided discovery learning model and in control class used guided discovery without web assisted. The result of the research showed that the average of critical thinking ability in the experimental class is better than control class which is in the experimental class is in the less effective category and control class in ineffective category.

Mathematical Critical thinking is one of  mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge.  Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the  abilities  of students' mathematics critical thinking.

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.

This research is motivated by learning activities that are still notes, memorization, and simple explanations from the teacher without requiring students to analyze a problem and try to solve the problems faced in learning. For this reason, the implementation of the Preparing, Doing, and Concluding (PDC) learning model is expected to be a solution to improve students' critical thinking skills. This research was conducted on grade IV / A students of SDN 003 Sungai Salak. This type of research is classroom action research. The instrument used was a critical thinking skills test. The results showed that the average critical thinking skills of students in the first cycle was 66.72 in the sufficient category, in the second cycle it was 75.52 which was included in the good category. Based on the research results, it can be concluded that the implementation of the Preparing, Doing, and Concluding (PDC) learning model can improve the critical thinking skills of grade IV / A students of SDN 003 Sungai Salak.
