Based on observations when apprenticed at SMAN 7 Pontianak it was known that students' critical thinking skills are still low. Therefore, a variety of learning models are needed to improve students' critical thinking skills. The purpose of this research was to determine the differences and effective learning model in improving students' critical thinking skills between students taught using the project-based learning model and the problem based learning model. The research method used was a quasi-experiment with a nonequivalent control group design. The data collection techniques used were measurement. The results showed a significant value of the T-test was 0.000<0.05. This means that there are differences in students' critical thinking skills taught using the project-based learning model and problem-based learning. The average value of N-Gain in the project-based learning model was 0.69 (moderate) while the problem-based learning model was 0.58 (moderate), so the project-based learning model is more effective than the problem based learning model on students' critical thinking skills.Keywords: Critical thinking skills, problem-based learning, project-based learning, cell material

Abstract. This research was conducted to improve critical thinking skills students through the application of the Project Based Learning (PBL) model on the material of simple harmonic motion. The research design was a quasi-experimental study with a control group pretest posttest design. The research was conducted at a high school in Samarinda with the number of research subjects consisting of 34 students. The instruments of the research were in the form of an integrated test description with skills critical thinking and a questionnaire of the student responses to the application of the PBL model. The result of the research showed that the of the PBL model (experimental class) improved students' critical thinking skills with N-Gain means of 0.61, while the conventional model (control class) improved students' critical thinking skills with N-Gain means of 0.38. There is a significant difference in critical thinking skills between classes using the PBL model compared to those applying the conventional model on the topic of simple harmonic motion.Keywords: problem based learning, critical thinking, simple harmonic motion.Abstrak.

In today’s 21st century, people are demanded to have the ability to communicate and to think critically. In addition, we are also expected to possess leadership qualities. In achieving such competencies, IT-Assisted Project Based Learning (PjBL) model can be used as an alternative. Hence, this study was conducted, aiming at determining whether there is an effect of Instagram-Assisted PjBL model on students' critical thinking skills in sociology subjects. This research was a Quasi-Experimental Study, with Nonrandomized Control Group Pretest–Posttest Design. The research data were obtained using objective tests in the form of multiple choice questions, which have passed validity, reliability, discrimination power, and difficulty level test. The data were analyzed using parametric statistical tests, in the form of comparative analysis and N-Gain. The results of the study showed that Instagram-Assisted Project Based Learning model had an impact on students' critical thinking abilities. The results of N-Gain test also showed that the increase in students of experimental class’ critical thinking skills is higher than that of the students in control class. This implies that Instagram-Assisted Project Based Learning models can be used as a supplement in strengthening constructivist-oriented learning theories.

Thinking Ability

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.
