<p class="Abstrak"><strong>Abstract:</strong> This classroom action research aims to describe the success of the RME approach assisted by origami manipulative media to improve the critical thinking skills of VA class students at SDN 1 Patrang Jember. The study was conducted in two cycles. The research subjects were VA class students. Based on research in the first cycle showed that: (1) learning by teachers reached 89.7% and by students reached 88.5% (2) students' critical thinking skills reached 76.8%. The data in the first cycle have not yet reached the criteria for success of the action, so that improvements are made to the second cycle. In the second cycle showed that (1) teacher learning reached 95.9% and by students reached 93.2%, (2) students' critical thinking skills reached 88.9%. So it can be concluded that the RME approach assisted by origami manipulative media can improve students' critical thinking skills.</p><strong>Abstrak:</strong> Penelitian tindakan kelas ini bertujuan untuk mendeskripsikan keberhasilan pendekatan RME berbantuan media manipulatif origami meningkatkan kemampuan berpikir kritis siswa kelas VA SDN 1 Patrang Jember.

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.

This research is motivated by learning activities that are still notes, memorization, and simple explanations from the teacher without requiring students to analyze a problem and try to solve the problems faced in learning. For this reason, the implementation of the Preparing, Doing, and Concluding (PDC) learning model is expected to be a solution to improve students' critical thinking skills. This research was conducted on grade IV / A students of SDN 003 Sungai Salak. This type of research is classroom action research. The instrument used was a critical thinking skills test. The results showed that the average critical thinking skills of students in the first cycle was 66.72 in the sufficient category, in the second cycle it was 75.52 which was included in the good category. Based on the research results, it can be concluded that the implementation of the Preparing, Doing, and Concluding (PDC) learning model can improve the critical thinking skills of grade IV / A students of SDN 003 Sungai Salak.
