“Development of E-Modules using the Context of Karate Sports Based on Indonesian Realistic Mathematics Education on Learning Materials for Arithmetic Operations in Class III SD N 08 Bonjo Alam

Abstrak

Learning often does not involve direct activities from students to be able to construct their own knowledge and discover the concepts being studied. Some of the things above can result in a lack of students' understanding of mathematical concepts which should be able to train students to think creatively in solving problems. As one of the basic sciences, Mathematics is one of the subjects that exist at every level of education, both from elementary school, junior high school, high school, to university. Mathematics is taught from an early age with the aim that students have the ability to solve problems which include the ability to understand problems, design mathematical models and be able to interpret the solutions obtained. Then an E-Module learning module is needed in the 2013 (2018) curriculum, with KD 4.1 Solving problems involving the use of arithmetic operations on whole numbers. So the authors have conducted research entitled "Development of E-Modules using the Context of Karate Sports Based on Indonesian Realistic Mathematics Education on Arithmetic Operations Learning Materials in Class III SD N 08 Bonjo Alam" This research is research development (Research and Development) using a 3-D model, namely Define, Design, and Develop (up to the stage of testing effectiveness). The research instruments included validity sheets and practicality sheets (teacher and student response questionnaires). The validators consist of 3 expert lecturers namely material, language and design validators. The instrument in this study used validity, practicality and effectiveness tests. Based on the validation stage of the mathematics E-Module, namely the material expert validator, language expert validator and design expert validator. The average result of the three validators is 94.3% with very valid criteria. From the aspect of material components, the mathematics learning E-Module obtained a validity percentage of 92.3% with very valid criteria. This shows that the developed E-Module is in accordance with the material. From the design aspect, the E-Module has a validity percentage of 93.8% in the very very valid category. This shows that the developed E-Module already has an attractive, good appearance, color matching, appropriate letter selection and clarity of learning instructions. From the aspect of the language component, the E-Module gets a validity percentage of 98.3% with a very valid category. This can show that the developed E-Module uses good and correct language, simple sentences and is easily understood by students. d Based on the results of practicality it can be explained that the practicality of the E-Module by the teacher is 95% with very practical criteria. This shows that the E-Module is very practical and well used by teachers in the learning process. Apart from teachers, practicality tests were also carried out on students. Practicality results by students were obtained through a student practicality test questionnaire. It can be explained that the practical percentage of the E-Module by students is 95% with very practical criteria. This shows that the E-Module is practically used by students in the learning process. Based on the results of the study, it can be concluded that the PMRI-based Indonesian module meets the valid, very practical, and effective criteria that can be used in learning in class III of SD Negeri 03 Alai Padang.
