The Development of learning devices with realistic mathematics education based in the pharmaceutical program to improve mathematic problem-solving

Abstract

Abstract This study aims of this research to describe the value of learning devices based on the realistic mathematics education that are developed, the improved student ability to solve problem mathematically which is taught through learning devices based on realistic mathematics education developed, and the student’s response to a learning device based on realistic mathematics education developed on a pharmaceutical program for 10th grade vocational high school students. Developed learning tools consisting of the learning implement plan and the student’s worksheet. This study uses development research with the model used is Plomp (Preliminary Research, Prototyping Phase, dan Assessment Phase). The research only did until the preliminary research covered the student’s analysis. Based on a student’s observation that a student’s mathematical problem solving ability is low because the learning tools have not supported the students in improving the problem-solving ability, the learning tools that teachers use are not in accordance with the student’s skill program, only a few teachers present problems reading for practicing the mathematical skills of students. The instrument used in this research is the validity test sheet, practical test sheet, and problem solving ability test.
