Abstract This study aims to know whether RME approach is effective in increasing the learning creativity at the eighth grade students of Barus Adventist Private Junior High School students. The research used an experimental method bu applying one group pretest posttest design. The sample of this study is 35 students which were taken by using the total sampling technique. The data collection techniques used observation and tests. The data collected are analyzed in two stages, namely descriptive analysis and inferential analysis. The research results, it is known that the description of using RME approach is on average 3.00 (good category). Furthermore, the description of student learning creativity before learning RME obtained an average value of 66.21 (enough category) and after learning RME obtained an average of 76.82 (good category). Based on the results of hypothesis testing, it can be known that the value of Sig. (2-tailed) of 0.000 < 0.005.

Abstract This study aims to develop teaching materials for flat shapes using a realistic mathematics education approach to teach students' mathematical problem solving skills and to determine the quality of teaching materials in terms of validity, practicality, and effectiveness. This research is a development research with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The subjects in this study were 28 grade VIII students of SMP Negeri 7 Padang Sidempuan. The research instrument used to measure the quality of teaching materials was in the form of expert validation questionnaires, student response questionnaires and post-test results of students' mathematical problem solving abilities. The expert validation questionnaire was used to measure the validity of the teaching materials while the student response questionnaire was used to measure the practicality of the teaching materials and the post-test results of students' mathematical solving abilities were used to measure the effectiveness of the class VIII students' teaching materials at SMP Negeri 7 Padang Sidempuan. The results of this study indicate that the quality of teaching materials is seen from the validation assessment of material experts with an average score of 75.5%, for the assessment of media experts with an average score of 78.33%, and for the assessment of linguists with an average score amounted to 90.67% with each score included in the eligible criteria. The overall results of the expert's assessment show that the teaching materials developed have "good" (decent) criteria based on the assessment by 6 experts with a percentage score of 81.5% in the "very valid" criteria. And the results of the questionnaire responses of students to teaching materials seen from the aspect of practicality with a percentage score of 92.78% in the "very practical" criteria and the post-test results of students' mathematical solving abilities seen from the aspect of effectiveness with an average score of 74.46 in the category " effective. So it can be concluded that the overall results of the study indicate that the teaching materials of flat shapes with a realistic mathematical approach to teach students' mathematical problem solving skills are valid, practical, effective and suitable to be used as learning tools.

The low creative thinking ability of elementary school students is the main research problem. This is because the learning that is carried out tends to be conventional and the lack of textbooks that support students to be active and creative in learning. A learning that supports student activity in learning is a contextual learning approach. By using textbooks that are relevant to students' situations, it is hoped that students' creative thinking skills will develop well through the learning process. The purpose of this study was to describe the validity of developing textbooks with a contextual approach in teaching elementary school students' creative thinking skills. The research method is to apply the ADDIE model which in this stage will specifically describe the development stage. The development of textbooks was carried out by giving assessments from 4 validators to textbooks in terms of format, language and content of textbooks. Analysis of the results of the assessment of the 4 validators showed that the average percentage score of textbooks on the format aspect was 77.00 (high), the language aspect was 85.83 (high) and the content aspect was 81.11 (high). Furthermore, the overall average is 81.31 (high). From the achievement of the average percentage score obtained, it was concluded that textbooks with a contextual approach in teaching students' creative thinking abilities fulfill aspects of validity and can be implemented in Civics learning for elementary school students.

Improving creativity in writing descriptive essays among students is one of the challenges in learning Indonesian, especially when the teaching materials are not directly connected to the students' cultural background. Therefore, this study aims to develop and analyze the validity of contextual textbooks based on local wisdom in order to improve students' writing creativity. This study uses the Research and Development (R&D) method with the Plomp development model which includes the Preliminary research stage, Prototyping stage, Assessment phase. The validity of the textbook is analyzed through the aspects of content feasibility, presentation feasibility, language feasibility, approach feasibility. The research instrument is a validation sheet of the textbook product. There are 4 validators involved in the validation process. The results of the study indicate that the textbook developed has a high level of validity in the four dimensions, which include content feasibility of 84.47%, presentation feasibility of 88.33%, language feasibility of 88.00%, and approach feasibility of 87.68%. And overall, the average percentage value was 86.25%. Based on the validation results, it was concluded that the developed textbook product was in good criteria. The implications of this study indicate that the development of local wisdom-based textbooks is not only culturally relevant, but also feasible in encouraging students' creativity in writing descriptive essays. The obtained textbooks can be tested in the field so that the effectiveness and practicality of the developed textbook products are found.

Students' low critical thinking skills are the main problem in this research. Apart from that, in learning it was found that the textbooks used were less varied and did not direct students to develop their thinking abilities. The learning model that can maximize thinking abilities is Brain Based Learning (BBL) and the learning approach that has clear stages and can be included in textbooks is the scientific approach. The aim of this research is to develop a textbook using the BBL model assisted by a scientific approach in teaching students' critical thinking skills. The development model used is the ADDIE Model which includes the stages of analysis, design, development, implementation, evaluation. Research instruments include validation sheets, questionnaires and tests. Research data includes product validation data obtained from expert validation, product response data obtained from student response questionnaire results, and students' critical thinking abilities obtained from tests. The data obtained was analyzed using quantitative and qualitative descriptive techniques. The data analysis carried out showed the results of achieving a Validity Mean Percentage Score (PRS) of 84.74 (valid criteria), the practicality of achieving PRS of 80.59 (practical criteria), and achieving PRS effectiveness of 89.31 (effective criteria). The data analysis carried out shows that the product developed meets the criteria of being valid, practical and effective and is suitable for use as a textbook. Based on these achievements, the development of textbook products with a brain-based learning model is feasible and good for use in teaching students' mathematical critical thinking skills.
