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.

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.

This research aimed  to analyze student worksheet development based on Problem Based Learning model in topic of Probability for Senior High School students of grade X. The instruments which were used in this research were the validation sheet of student worksheet for math lecturer and teacher in order to fulfill the validity aspect, the student scoring sheet in order to fulfill the applicability aspect, and critical mathematic thinking ability test in order to fulfill the effectiveness aspect. The result of the research showed that the student worksheet which was based on Problem Based Learning model had fulfilled the requirements and appropriateness standard based on content, design, and language expert. The data analysis of t-test towards of critical thinking ability showed that the critical thinking ability of students with Problem Based Learning model worksheet was higher than the critical thinking ability of students without Problem Based Learning model worksheet.

This study aims to determine whether there are differences in the ability to solve problems and think creatively in mathematics students who are taught with the problem based learning model with the two-stay-two stray cooperative learning model in class X SMA Negeri 2 Range of TP 2018 / 2019. This research is research quantitative research with quasi-experimental type. This sampling technique uses the Cluster Random Sampling technique. The sample of this study was students of class X-1 and X-2 of SMA Negeri 2 Kisaran T.P 2018/2019, amounting to 60 students. The test instrument used to determine students' creative problem solving abilities and mathematical creative thinking is to use a test in the form of a description. Data analysis was performed by analysis of variance (ANAVA). These findings show: 1). There is a difference in the ability to solve mathematical problem of students who are taught with the Problem Based Learning model and the Two Stay-Two Stray cooperative learning model in the material of the Three Variable Linear Equation System; 2). There is no difference between students' creative thinking abilities in mathematics taught by the Problem Based Learning model and the Two Stay-Two Stray cooperative learning model in the Three Variable Linear Equation System material; 3). There is a difference in the ability of problem solving and mathematical creative thinking of students who are taught with the Problem Based Learning model and the Two Stay-Two Stray cooperative learning model in the material of the Three Variable Linear Equation System; 4). There is no significant interaction between the learning models used on the problem solving abilities and students' mathematical creative thinking in the Three Variable Linear Equation System material. The conclusions in this study explain that there are differences in students' problem solving abilities and creative mathematical thinking that are taught with the Problem Based Learning Model and the Two Stay-Two Stray Cooperative Learning Model.

Education is a significant factor to shape human beings as a whole. The ability to think for humans plays an important role to develop information. The issue of lack of ability to think critically in Sahida Lemah Abang Vocational High School needed to be addressed. One learning model that can be utilized to guide students to think critically is Problem Based Learning (PBL) using an e-module as the resource of learning material. The study aims to examine the implementation of Problem Based Learning model using e-module and its influence on students' critical thinking ability.  This study used a quasi-experiment with nonequivalent control group design as its research design. In using the research design, two observations have been conducted; one was before the experiment called Pre-Test (O1) and one after the experiment of this study called the post-test (O2). There are two samples in this study; one is the experimental group and the other is the control group. The study was done in Sahida Lemah Abang Vocational High School. The data was gathered by using tests and observation sheets of the learning process. The result in this study shows averagely that the implementation in each of the learning stages has gained 95.7% which is in the category of very good value. The most significant difference is from the fifth indicator "developing strategy and tactic", n gain of experimental class and control class is 5.83 and 0.23 respectively. As the result of the hypothesis test is Sig. 0.035 which means that there is a significant difference in students' ability to think critically between the students in the experimental class and the control class, the students in the experimental class think more critically than the students in the control class.
