Abstract

The purpose of this study were (1) To analyze the effectiveness of learning devices based on the developed realistic approach;(2) To analyze the improvement of students' mathematical problem solving skills which taught through learning tools based on Realistic Approach; and (3) analyzing the process of answers that made by the students in mathematical problems. The topic in this study was the comparison in grade VII of Junior High School 27 Medan. This study done through two stages, the first stage was the development of learning device based on realistic approach using Thiagarajan, Semmel and Semmel (Four-D), and the second stage tested the learning tools based on realistic approach developed in VII-5 and VII-7 grades Junior High School 27 Medan. Based on I and II trial results were obtained that: 1) learning tools based on realistic approaches are effective, reviewed from a) mastery of classical student learning; b)achievement of learning objectives; c) ideal learning time and d)student's response to activity and learning tool based on realistic that developed is positive. 2) Improved students' mathematical problem solving abilities and 3) The student response process in trial II is more variety and better than trial I. Learning tools that produced were the lesson plans, student worksheets, teacher textbooks, student textbooks, and students' mathematical tests for VII grade of Junior High School.
