This study aims to: (1) To determine the effect of problem-based learning models on mathematics critical thinking skills of junior high school students; (2) To find out the attitudes of students towards the problem-based learning model. The population in this study were eighth grade students of Junior High School of 28 Medan. By random sampling selected class VIII-F as an experimental class as many as 40 students and class VIII-E as a control class as many as 40 students. The data used in this study are quantitative data and qualitative data. Quantitative data are data obtained from tests of students' critical thinking skills and qualitative data, namely data obtained from student attitude questionnaires. Based on the analysis of research data, obtained the following results: (1) the results of regression analysis obtained the equation = 51.89 + 23.57X means that the problem-based learning model has a positive effect with an average value of 75.46 mathematical thinking skills of students . From the results of the correlation it was found that the influence of the problem-based learning model was strong enough with the results of the correlation coefficient of 0.568 and the coefficient of determination of 32.3% so it can be concluded that the problem-based learning model influences students' critical thinking skills. (2) Based on student attitudinal response results it can be concluded that the student response is very positive towards the problembased learning model with an average of ≥ 86.03.

Abstract-this study aims to know, analyze and evaluate the differences of students’ critical thinking skills by using problem based learning model and conventional models. This study uses a quasi-experimental method with quantitative approach using Nonequivalent (Pretest-Posttest) Control-Group Design. The data collection technique used in this study is using the test. The data analysis technique is done by independent t-test sample. Moreover, this research shows the significant differences if seen from the average of percentage of  experiment class; pretest is less while posttest is so gratified. The result of pretest control class is less and posttest is enough The results of this research give the recommendation for teachers and next researchers to apply problem based learning model to enhance critical thinking ability of students. In addition, problem based learning model is also expected to encourage students to be able to solve problems encountered in everyday life, especially in social studies.Keywords: Problem based learning, conventional learning model and critical thinking.

The purpose of this study was to determine whether there were differences in critical thinking skills and to describe critical thinking skills among students taught using the Search learning model, Find, And Construct Together (SFCT) and conventional learning models. The research method used is a combination research method with sequential explanatory design. Quantitative data samples were students of class XI MIPA 1 and XI MIPA 2, this quantitative research was obtained by testing students' critical thinking skills. Analysis of the data used is the t test with the prerequisite test, namely the normality test and homogeneity test. Qualitative research subjects were 9 students. The nine students were selected based on high, medium and low critical thinking skills. While the collection of qualitative data is done by observation, interviews, and field notes. The results showed that (1) Based on the results of quantitative data analysis with hypothesis testing using SPSS 20 software, the Sig 2-tailed value was obtained = 0.009. Because the Sig value = 0.009 <0.025 then H0 is rejected. This means that it can be concluded that there are significant differences in critical thinking skills between students who are taught by the SFCT learning model and students who were taught using conventional models. (2) Based on qualitative data analysis obtained from interviews, it can be concluded that students like to be taught using the SFCT model and as many as 80.56% of students fulfill four indicators of critical thinking, while students are not happy to be taught using conventional models and only 63.86% students who fulfill the four indicators of critical thinking.

This study aims to determine the effect of the problem-based learning model (PBL) with a scientific approach to critical thinking skills of class X students of Al-Ma’arif Pandan Indah Islamic High School 2016/2017 academic year. The type of research used is quasi-experiment with Nonequivalent control group design. The population in this study were all students of class X Islamic High School Al-Ma’arif Pandan. The sample used consisted of two classes taken using nonprobability sampling techniques, namely class XA as the experimental class, and class XB as the control class. The technique of collecting data on the implementation of RPP using the observation sheet and critical thinking skills of students was measured using a test in the form of a description question that had been validated by 2 expert experts. Data analysis of critical thinking skills carried out by t-test found that t-count = 2.58> 2.042. Based on the results of the analysis it can be concluded that the problem-based learning model with a scientific approach significantly influences students' critical thinking skills.

KERANGKA KONSEPTUAL MODEL CONCEPTUAL PROBLEM BASED LEARNING UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS SISWA SEKOLAH MENENGAHAbstractLearning to facilitate critical thinking requires a set of specific learning models that aims to trains critical thinking skills that in this study is the development of conceptual problem based learning model. This study aims to develop a conceptual problem-based learning model to facilitate high school students’ critical thinking skills. This study is a development research that will produce a model of learning products, namely a valid Conceptual Problem Based Learning Model to facilitate high school students’ critical thinking skills. Validation of CPBL learning model includes two components namely content validity and construct validity. The result of data analysis shows that the CPBL model can be declared valid with reliability percentage of 97% (reliable) based on syntax model assessment that is: 1) prior knowledge; 2) organize; 3) investigate; 4) analyze; 5) evaluate; to facilitate critical thinking skills.AbstrakPembelajaran untuk melatihkan berpikir kritis memerlukan satu set model pembelajaran yang spesifik melatihkan kemampuan berpikir kritis yang dalam penelitian ini pengembangan model conceptual problem based learning.
