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.

Solution material is one of the materials that requires a student's level of understanding at the critical thinking level. Critical thinking skills train students to learn to find and solve problems using scientific methods based on real experiences encountered and experienced directly. To be able to find the concept of knowledge based on existing realities, an appropriate learning model is needed, namely a problem-based learning model. This study aims to determine students' critical thinking skills. The type and design of this research is development research with a nonequivalent control group design. The samples of this research were students of semester 2, Biology Education Study Program, University of Flores. This research was conducted from April-June 2020. Data were collected using the critical thinking ability test technique of students in the chemical solution subject, followed by processing and analyzing data using the prerequisite analysis test in the form of normality test, homogeneity test, and t-test. The data analysis shows the significance value of the normality and homogeneity test, namely α> 0.05, while for the t-test α <0.05. From these results prove that problem-based learning can improve students' critical thinking skills in chemistry subject matter solution

Problem-based learning is characterized by the existence of a real problem as the context wherein students learn critical thinking skills, problem-solving, and knowledge acquisition. The concept of critical thinking gains popularity to help students obtain the ability to conduct fact analysis, support opinion with an argument, and problem-solving. The majority of Indonesian vocational school students, however, have difficulty in developing critical thinking skills and problem-solving. This research was purportedly designed to evaluate the differences of students' critical thinking ability in response to the application of various problem-based learning model namely Fishbone diagram, problem-based learning model, and expository learning model. A quasi-experimental design was applied to assess students' critical thinking. The findings indicate that there was a significant difference in students' critical thinking ability responding to the learning models. In summary, the research proposes the problem-based learning as an alternative learning model to improve student’s critical 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.
