The Development of Learning Devices Based Realistic Approach for Increasing Problem Solving Mathematics Ability of Student in SMPS Gema Buwana

Abstract

This type of research was a of learning devices with the aim to produce devices based learning approach that was valid realistic mathematics, practical and effective, and all the instruments of research related to the application of these devices in the learning of mathematics on the subject of rectangle and square for seventh grade students of SMP. This study was conducted in two stages, namely the first stage was the development of learning tools. The development of devices based learning mathematics realistic approach with reference to the development model learning device according to Thiagarajan, and Semmel Semmel ie 4-D models (four D models). The second stage was the implementation of learning devices that were considered feasible. The design of the trials was a one-group posttest-only design. The findings of the research were: 1) the resulting learning, such as: lesson plan, student books, student activity sheet, and test problem solving had met the criteria of good / valid; 2) The effectiveness of the learning device inferred based on: (i) complete student learning classical at the first trial amounted to 85.17% and in the second test by 90%, (ii) achievement of learning goals at the trials I was not achieved in a matter of question number 3 and 4 and no trial II was reached on each item, (iii) the performance of the ideal time at the trial I and II trials were ideal, 3) The student’s response to the component and learning activities was postive.
