The Ministry of Education and Culture emphasizes that the five elements of mathematical ability are very important for students, one of which is mathematical reasoning ability. Current conditions show that students' mathematical reasoning skills are still low, this is influenced by the lack of independent learning habits, limited learning resources, and the lack of variations in learning approaches. To overcome this challenge, learning strategies that support mathematical reasoning skills are needed, such as the Realistic Mathematic Education (RME) approach. The implementation of RME requires appropriate teaching materials. Therefore, this research aims to produce RME-based social arithmetic teaching materials. The research adopted the 4-D development model which includes Define, Design, Development, and Disseminate. Data collection techniques used were interviews, questionnaires, and tests. The instruments used were validity sheet, learner response questionnaire, and mathematical reasoning ability test.
In the Define stage, researchers set and clearly identify the requirements and needs related to the development. Activities carried out in this stage include preliminary analysis of the end, researchers analyze teaching materials in schools and data collection from various sources. At the learner analysis stage, data regarding the characteristics of students were collected. At the task analysis stage, researchers analyzed the learning outcomes of the Merdeka Curriculum, especially in Phase D related to social arithmetic material. At the concept analysis stage, researchers determine, explain, and design in a structured manner the material to be presented in teaching materials. At the learning objective specification stage, researchers identify the objectives to be achieved in learning which are adjusted to task analysis and concept analysis, which will later be integrated with the preparation of teaching materials to be developed.
At the Design stage, researchers design teaching materials with steps including compiling tests, selecting media, determining the format, and designing the content of teaching materials. At the media selection stage, researchers decided to use visual media in the form of illustrations and teaching materials in printed form. At the initial design stage, researchers began developing teaching materials according to the plan that had been made.
At the Development stage, researchers conducted a formative evaluation involving expert assessment, one-on-one evaluation, limited trials, and field trials. Expert assessment involved discussions with the supervisor and validation by three mathematics education lecturers, focusing on aspects of graphics, content, presentation, language, Realistic Mathematics Education (RME), and mathematical reasoning skills. The validity of the teaching materials reached 86.40%, classified as very valid. Validators provided constructive suggestions, such as adding educational images, adding captions to illustrations, communicative improvements to the introductory editorial, adding instructions to the test, and presenting more comprehensive apperceptions.
At the one-to-one evaluation stage, learners provided constructive feedback, including the correction of word errors in learning objective B1, consistency between question captions and illustrations, the addition of icons on subtitles for a more attractive appearance, and improvement of question wording to make it clearer. A typing error was also found in formative test 1, and learners recommended clarifying the illustration for question number 2 of formative test - 2 to make it more focused and concrete. This input was used as the basis for researchers to improve teaching materials. In the limited trial stage, students responded positively, giving an average assessment of teaching materials of 85.92% with a very practical category. Learners provided suggestions for the addition of examples in the introductory material, adjusting the purchase price of the headscarf, and improving the editorial in the introductory material for learning activities - 5. At the field trial stage, the learners' response to teaching materials reached 82.81%, indicating that the teaching materials were included in the practical category. Learners' suggestions involved detailed explanations of illustrations, additional images of discounts, and adjustments to the context of questions to improve clarity and relevance in teaching materials.
After completing the large group trial and making improvements based on feedback, researchers began the effectiveness test of teaching materials. The analysis results showed that the average posttest of the experimental class was higher than the control class. N-Gain analysis showed a "moderate" increase for the experimental class and "low" for the control class. Realistic Mathematics Education (RME)-based social arithmetic teaching materials proved effective in improving students' mathematical reasoning skills. Thus, it can be concluded that the social arithmetic RME teaching materials have met the criteria of valid, practical, and effective in accordance with the established standards.
At the product Disseminate stage, teaching materials are submitted to schools participating in the research and are expected to be used as learning resources and references for the development of teaching materials on other materials. In addition, the results of the research were delivered through publications in accredited journals in the form of articles and disseminated through research result seminars, in accordance with the principles of effective and wide dissemination.
