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.

Education functions to upgrading, forming, character and develop civilization nation. Having the ability to think and actions to effective and creative in the realm of abstract and concrete can be used as self development independently. Students need to armed with critical thinking skills, systematic, logical, creative, and cooperate effectively to obtain, choose, and manage an information. Mathematics learning is directed to develop critical thinking skills and discussed open and objective because mathematics having strong and structure clear and links between the concept of the one with another concept. By analyzing learning needs of mathematics, formulate and designed a learning programs, choose a strategies and evaliated them correctly to get good results. The ability critical thinking is very important in studying new matter and that known way, and learn to ask effectively and reach a conclusion consistent with the facts. Mathematic learning with problem based learning is the concept of better used activity of the student during learning. In accordance with statements from Westwood (2008: 31) stated that PBL: 1) propel oneself directly in learning, 2) prepared students to critical thinking and analytical, 3) give opportunity to students to identify, find and use numerous this approuch in should think, 4) is the learning is very closely related to the real world and motivate students, 5) involving activeness in integrating information and skills of various the discipline, and 6) knowledge and strategy by the possibility of will be maintained and tranferred to the learning situation other, improve the ability to communicate and the social skills needed to cooperation and teamwork. By chance the learning process as an alternative in solving mathematical problems with using the ability critical think an to cultivate the scientific attitude of student.

This article explores the skills and difficulties in critical thinking of junior Indonesian high school students in mathematics learning. Fifty students of grade IX who were purposive randomly selected from state junior secondary schools in Yogyakarta City were involved as the research subjects. The data were obtained from the test of mathematical critical thinking on the material of geometry. The test consisted of four items that describe each aspect of critical thinking skills, namely interpretation, analysis, evaluation, and inference. The analysis was done by showing the steps of the students ‘answers. The result indicated that the average of the aspects of mathematical critical thinking of students were on the high criteria with students’ greatest difficulties being in the analysis standard. Meanwhile,the average student success in the interpretation standard was 82%, the standard of the analysis was 46.25%, the evaluation standard was 78.25%, and the inference standard was 77%. Furthermore, from the results of the sample students’ exploration answers, it is expected that future teaching should not only focus on fluency in calculation but also on training the students in how to explain the solution steps of the problem solving process as this is important part in critical thinking.

The essence of mathematics learning is the ability to solve math problems. Differences in ability, one of which is the suspect cognitive style. Based on the cause of the necessary mathematical problems of the students, cognitive style consists of a type of reflection and impulsive. So that the focus of this research is to analyze students' critical thinking skills in solving mathematical problems based on different types of reflective and impulsive cognitive style. Causal-comparative studies are needed to analyze the problem. The population of this study is composed of students of class VII SMPN 1 Susukan Cirebon. While the sample search uses the intentional sampling technique with the number of research samples 31 students. The technique of data collection using the Cognitive Style TMF test (correspondence familiar figures Test) and description Test (essay) Mathematics of critical thinking. The hypothesis test used is the t-test (T-test for independent samples). The results of the research show that the distribution of cognitive styles of students at SMPN 1 Susukan Cirebon, dominated by reflective-type cognitive style students (74% of students), while a small part of the students type of impulsive cognitive style (26% of students ). Critical thinking ability of reflective type students of cognitive style is better than the type of impulsive cognitive style students

This study aims to improve critical thinking skills and mathematics learning outcomes of fourth-grade students of SD Tingkir Tengah 02 Salatiga in the second semester of the 2018/2019 academic year. Critical thinking and learning outcomes are low because the teacher uses the lecture method. The author chooses the Open-Ended model assisted by powerpoint media as a solution. Research procedures include planning, action, observation, and reflection. The results showed an increase from the initial condition with 9 students or 25.71% completed and 29 students or 74.29% not complete. The implementation of the first cycle results obtained 29 students or 82.86% completed and 6 students or 17.14% did not complete. Cycle II as a follow-up and improvement of the first cycle with the acquisition of achieving attainment of 35 students or 100%. The results obtained by the conclusion of the application of Open-Ended learning assisted by powerpoint media can improve critical thinking skills and mathematics learning outcomes of fourth-grade students of SD Tingkir Tengah 02 Salatiga second semester of the 2018/2019 academic year.

This research is to determine the effect of learning model and critical thinking skills toward mathematics learning achievement of class XI IPA students in senior high school in Gianyar by controlling students’ numeric aptitude. This research used treatment by level 2x2 design and analysis of covariance. The sample was 80 people using multistage random sampling. The results by controlling numeric aptitude are: students learning achievement taught using PAIKEM model is higher than those taught in conventional model. There is an interaction effect between learning model and critical thinking skills toward students’ mathematics achievement. Given high critical thinking skills, students taught using PAIKEM models displayed higher results compared to those in conventional learning who were best in a lower critical thinking skills. Finally, based on the results, it can be recommended to SMA Mathematics teachers to increase students’ Mathematics achievement by using PAIKEM model accurately and to see of students critical thinking skills.
