Development of Teaching Materials Based On Open-Ended Approach with Autograph Assistance to Improve Mathematical Creative Thinking Ability of Junior High School

摘要

Open ended approach is a learning approach that presents a problem that has more than one answer or settlement method. Open ended approach encourages students to develop creative ideas and mathematical mindset by remembering previous mathematical concepts, so that with the open-ended approach, students are expected to have a much better mathematical creative thinking ability. The purpose of this research is to analyze the improvement of students creative thinking ability by using learning materials developed through autograph assisted open-ended approach. This research is a development research using Thiagarajan 41) model with define stage, design, develop, an dessiminate. The subject of this research is Junior High School Swasta Imelda Medan. The teaching materials that will be developed in this study are learning tools that include Learning Implementation Plan (RPP), teacher book (BPG), Student book (BS) and, student worksheet (LAS) and creative thinking ability test. From results of trial I and II by using learning materials developed through autograph assisted open-ended approach effectively used in learning mathematics so that there is an increase in creative thinking ability of students.
