Abstract: This research is motivated by low students' critical thinking ability. This is caused by the ineffectiveness of learning in the classroom in the learning process with conventional model while the students who receive it more passive and afraid to express the assumption because they think that math is hard to learn. So teachers need to apply a fun learning system and more real in improving the ability to think critically by using Realistic Mathematics Education Approach (RME) to help critical thinking of students to be more critical. This research is an experimental research. The population in this research is all students of class VII SMPN 2 Kota Jambi Academic Year 2017/2018. Sampling using Random Sampling technique, which is taken class VII A and VII D where two classes are given different treatment. This study aims to determine the difference of Realistic Mathematics Education (RME) approach to critical thinking skills of the seventh grade students of SMPN 2 Kota Jambi, the subject of the set. Based on Post-test results can be seen that the critical thinking ability of students of class VIIIA (experiment) SMP Negeri 2 Kota Jambi on the set material, the average value is 76.84 with standard deviation 6.96 whereas in class VIIID (Control) average of 72.75 with standard deviation of 11.64. Based on these calculations there is a difference between the experimental class and the control class, this is the influence of the approach of Realistic Mathematics Edication (RME).Keywords: Realistic Mathematics Education (RME) Approach, Student Critical Thinking Ability

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.

This study originated from the lack of utilization of learning media during the learning process. Teaching methods used by teachers are less varied so that learners are only trained in cognitive abilities only while for high-level thinking skills such as critical thinking ability is still low. One alternative that can be done to improve the skills of critical thinking is to utilize the Software Tracker media. This study aims to determine the improvement of critical thinking skills of learners through the use of Software Tracker media on the material impulse and momentum. The research method used is Pre-Experiment with design One-Group Pretest-Posttest Design. The sample of this research using Purposive Sampling technique. The research instrument used in this research is the critical thinking skills of the students of impulse material and momentum to measure the critical thinking ability of learners. The data analysis technique uses normality test, and t test to normalized n-gain value from pretest and posttest value of learners using Microsoft Excel. The results showed that the critical thinking skills of learners increased after utilizing the Software Tracker media during learning. The result of this research is proved from the significant value of ttable test of 1.691 while t count is 24.53 which means H0 is rejected and Ha accepted. The results of this study indicate that the use of Software Tracker media on the material impulse and momentum have a positive impact on improving the critical thinking skills of learners.

The purpose of this study is to find out whether there are: (1) the influence of the scientific approach on students’ critical thinking skills; (2) the influence of learning independence on students’ mathematical critical thinking ability; (3) the interaction between the scientific approach and the learning independence of students’ critical thinking skills. This research is a quasy experimental design research with 2x3 factorial design. Sampling technique in this research use probability sampling with cluster random sampling. The research instrument used is questionnaire self-reliance learning and test of critical thinking ability mathematically. Data from the results of tests of mathematical critical thinking ability were analyzed using anava test of two unequal cell paths and further tests using a double comparison test with the Scheffe method. The results showed that: (1) there was an influence of the scientific approach on students’ critical thinking skills; (2) there is influence of learning independence to students’ critical thinking ability mathematically; (3) there is no interaction between the scientific approach and the learning independence of mathematical critical thinking skills.

Mathematics has an important role at every level of education and is a means of solving problems in life. Mathematics will increasingly provide benefits with the support of the ability to think logically-reflective to make rational decisions that are believed to be true. Student worksheets as a learning medium can combine mathematics and critical thinking skills in learning. This study was aimed to produce student worksheets based on realistic mathematics education to improve students critical thinking skills that are valid, practical and effective. The research was conducted by using Borg & Galls R&D design, but only eight steps were taken, in the form of preliminary research, development planning, initial product design development, initial product validation, initial product revision, trial use, product development revision and effectiveness testing product. The research subjects were 58 grade VI students of SDN Sumberagung 01 Jember. The data were collected by using documentation, interview, product validation, and test learning outcomes. After the data were collected, the data were analyzed by using the following techniques: product validation, t-test, and relative effectiveness test. The results of the study stated that the validity of the student worksheet development product showed 93.96% (very worthy), the productivity of the student worksheet product showed 74.71% (practical), the field test results showed that the worksheet product from this study was more effective than with the previous product, and the relative effectiveness level obtained was 62.57% (high effectiveness). Thus, it can be concluded that the product of developing student worksheets based on realistic mathematics education can improve students critical thinking skills on the fraction counting operation material.
