Design of Realistic Mathematics Education Approach to Improve Critical Thinking Skills

Abstract

Critical thinking skills are skills needed in the modern era, especially in the industrial era 4.0, as today, having critical skills will facilitate students in solving problems in life. The purpose of this study is to design statistical material for RME-based teaching materials to improve students' critical thinking skills. The method used in this study is ADDIE. In the ADDIE method, there are five stages; (1) Analysis, (2) Design, (3) Development, (4) Implementation, and (5) Evaluation. This research is only limited to analysis and design. The subjects in this study were seventh-grade students at Patuk 4 Public Middle School. Data collection instruments include observation sheets and interview guidelines and validation sheets. The results of this study indicate that the design of teaching materials has been adapted to the characteristic of students using the ADDIE method. The design includes cover, preface, concept map, Core Competencies (KI), Basic Competencies (KD) and Competency Achievement Indicators, table of contents, module activities, evaluation, and summary. Teaching material in statistical learning is based on RME steps to improve students' critical thinking skills. This research can be continued at the development, implementation, and evaluation stages in learning.
