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.

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

<p><em>The background of this research is to analyze the ability to think critically and reasoning in solving mathematical problems of elementary school students. This research method uses a qualitative descriptive method which was carried out at SD Negeri Pengarasan 01 with the research subject of class V (five) students as many as 30 students, which were divided into groups of high ability students (KT), medium ability (KS), and low ability (CR). The research data are 1) the ability to think critically in problem solving, 2) the ability to reason mathematically. Sources of data are written test scores of critical thinking skills to solve problems and scores of mathematical reasoning ability tests and interviews. The ability of students who are accustomed to getting structured questions makes it difficult for them to reason about questions that are in the form of story questions. The application of the Problem Based Learning model is suitable for use in elementary schools in building students' critical thinking and reasoning abilities. This ability will make students able to solve problems that arise in the problem.</em></p>

The ability of students to think critically in mathematics is is still low. The lack of learning tools that are considered to facilitate students' mathematical critical thinking skills is one of the cause it. The purpose of this study was to develop a mathematics learning tool with a quality problem-based learning (PBM) model to facilitate students' mathematical critical thinking skills. The learning tools developed consisted of a syllabus, lesson plans (RPP) and student worksheets (LKPD) on the matrix material for class X SMK. This research was a development research using the Borg and Gall model. The development consists of six stages, namely: 1) research and data collection; 2) planning; 3) development of the initial product draft; 4) initial field trials; 5) revised trial results; and 6) dissemination and implementation. The subject of this research trial was the students of SMK Nurul Falah Pekanbaru. The instrument used was validation instrument for the syllabus, lesson plans, and student worksheet. Based on the results of the validation data analysis, it shows that the learning tools developed were very valid. The results of the validation of the syllabus were 85.11; the average RPP score was 86.02; and the average LKPD score was 86.40. The average student response questionnaire to the initial field trial was 85.93 with the very practical category. The learning device developed was valid and practical for use by class X SMK students.

This research aims to enhance critical thinking abilities through the use of problem-based learning in the Social Science Basic Concepts course. The research method used is Classroom Action Research, which is based on the Kemmis and Taggart model. This research was conducted in two cycle, with the researcher serving as a lecturer and observer during each cycle. The subject of the research was elementary school teacher education. The data collected are presented in table format and analyzed quantitatively in a descriptive manner. The findings indicated that implementing the Problem Based Learning model can help students improve their critical thinking abilities. The results of critical thinking observations in cycle 1 were 39% (poor), and the results of critical thinking skills tests improved from 26% (poor) to 54% (fair). Cycle II was conducted using the same model, and the observation results for critical thinking skills increased from 39% (poor) to 78% (good).  The increasing of students pass critical thinking skills tests from 54% (fair) to 91% (good). It can be concluded that using the Problem Based Learning model can help elementary school teacher education students improve their critical thinking skills.
