Practicality of Learning Design Based on Realistic Mathematics Education of Derivative Topic for Grade XI Senior High School

Abstract

The derivative is one of the important subjects in mathematics. One of the goals of derivative learning is that students can solve math problems in real life. In this study, derivative learning design was developed based on Realistic Mathematics Education to make the products that consist of teacher books and student books to improve students’ mathematical problem-solving skills. The development models are used Plomp and Gravemeijer & Cobb models. Data collection was the form of questionnaires filled out by teachers and students. Then, the data is analyzed by using descriptive analysis. The results of this study can be concluded that the practical value of teacher response 81.25% and the practicality value of student response is 82.04%, so the design of learning derivative topics based on Realistic Mathematics Education has been categorized as practical. It means the RME-based learning design of derivative topics developed in teacher and student books can be used to develop students’ mathematical problem-solving skills.
