The Development of HOTS-Based Mathematics Teaching Materials in Elementary School

Teaching material is one component that occupies an important role in the learning process. Teaching material with HOTS component will be able to clearly distinguish ideas or ideas, argue well, be able to solve problems, be able to construct explanations, be able to hypothesize, and understand complex matters more clearly. The research aims to produce valid, practical, and effective HOTS-based mathematics teaching materials in elementary schools. The research type is research and development (R&D). The subjects of this study were students and teachers of SDN 4 Ngawen Blora. Data collection techniques used were interviews, questionnaires, and tests. The research result presented is based on the results of limited trials. To this research, it was found that the average mathematics learning achievement increased from 57.50 to 86,50. The prototype of HOTS-based mathematics teaching materials that was developed has shown good results with a percentage of assessment by the teacher of 95.45%. Students show an interest in HOTS-based mathematics teaching materials. Students feel challenged by the activities and learning activities presented. However, a few things need to be fixed, that is unclear pictures of the presentation aspect to students. Additionally, the teacher also provides suggestions and input on improvements to the HOTS-based mathematics teaching material prototype. The suggestion given includes replacing unclear images and providing explanations that match with the image, enlarging the image size that contained in the prototype, and correcting typographical errors. Moreover, the revised prototype results will be used in further trials.
