DEVELOPMENT OF TEACHING MATERIALS BASED ON REALISTIC MATHEMATICS MODELS EDUCATION (RME) ORIENTED TO CRITICAL THINKING SKILLS IN MATHEMATICS LEARNING AT CLASS IV MI/SD

Abstract

The research was motivated by the low critical thinking abilities of students caused by many factors, including the use of teaching materials and learning media that was not optimal. Teaching materials have not been adapted to the characteristics of students and the demands of the Independent Learning Curriculum, causing students' critical thinking abilities to be inadequate. The aim of this research is to develop teaching materials based on a realistic mathematics education model that is oriented towards critical thinking skills for class IV SD/MI.  This type of research is R&D development research using the ADDIE model which consists of 5 stages, namely starting from analysis, design, development, implementation, evaluation. The instruments used in this research were validity questionnaires, practicality questionnaires, and effectiveness test questions. The validity test was given to 3 expert validators in terms of content, language and construction aspects. The practicality test was given to one educator and 24 students in class IV. The effectiveness test was given to 24 class IV students.  The research results show that the product in the form of teaching materials based on the realistic mathematics education model is valid, practical and effective. Validity shows very valid with an average score of 94% with a percentage of content feasibility of 95%, construction feasibility of 97% and language feasibility of 90%. The product practicality test was 86% in the very practical category. Meanwhile, effectiveness is categorized as effective with an average score of 75.16%. Teaching materials meet the quality of products that are valid, practical, and effective and can be used to train students' critical thinking skills.
