THE EFFECT OF PROBLEM BASED LEARNING AND CRITICAL THINKING ON HIGH ORDER THINGKING ABILITY            AbstractThis study aims to determine the effect of problem-based learning model and critical thinking skills on students' high-order thinking about optical materials. Quasi-experimental method with two-way ANOVA design was used to conduct this study with 34 second semester physic education students of IKIP PGRI Pontianak. Data of students’ higher order thinking ability was obtained from multiple choice test with reason while the data of students' critical thinking ability was measured using multiple choice test. Based on the results of data analysis, it can be concluded that: (1) there is an influence of the problem based learning model on high student's thinking ability, (2) there is an influence of high critical thinking ability and low critical thinking ability on high student's thinking ability and (3) the interaction between the application of problem based learning model with the ability to think critically to the students' high level of thinking ability. AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh penerapan model problem based learning, keterampilan berpikir kritis dan interaksinya terhadap kemampuan berpikir tingkat tinggi mahasiswa pada materi optika.

This study aims to improve students' critical thinking skills through the application of the Problem Based Learning model to students. This model, if applied properly, can train students in solving contextual problems. The purpose of this research is to improve the critical thinking skills of students in class IXH MTs Darul A'Mal Metro City through the application of the Problem Based Learning model on population and environmental materials. classroom action research) using the Kemmis and Mc Taggart model where each cycle consists of planning (planning), implementation (action) and observation (observe), and reflection (reflect). The researcher acts as the designer of the action as well as the executor of the action, while the partner teacher acts as an observer. The research was conducted at MTs Darul A'Mal Metro in August-September. The research subjects were students of class IXH, totaling 24 male students. Data collection techniques used critical thinking ability observation sheets, critical thinking learning outcomes tests, field notes, and documentation. Data analysis was carried out by analyzing qualitative data consisting of data reduction, data presentation, verification and drawing conclusions. The research action is said to be successful if it reaches the predetermined success criteria of 75%. The results of the study based on observations showed critical thinking skills in the first cycle reached 57.80%, while in the second cycle it reached 79.38%, which means an increase of 21.58%. Based on the results of the critical thinking ability test in the first cycle, there were 54.17% of students who achieved the criteria for completeness, while in the second cycle, 79.17% completed the KKM. The conclusion of this study is that the Problem Based Learning learning model can improve students' critical thinking skills on population and environmental material in class IXH students in the 2016/2017 academic year at MTs Darul A'Mal Metro City.

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.
