Development of learning tools: learning constructivist mathematics to improve creative thinking ability

Abstract

The purpose of this study was to determine the implementation of learning constructivist mathematics through Guided Discovery Learning assisted with the Shapes Doll to improve Mathematical Ability of students Creative Thinking effective with valid and practical tools. This research is a development research that refers to the modified Plomp model. Learning tools developed consist of syllabus, lesson plan, worksheet, and Test of creative thinking ability. Test data is processed by one sample t test, z proportion test, comparative test, regression, and Gain test. The results of the development of learning tools: (1) learning tools that was developed valid according to the validator with an average syllabus validation value of 4.29, lesson plan 4.37, worksheet 4.27, and Test 4.02; (2) effective learning, by achieving: a) The experimental class mathematical creative thinking ability reaches class average completeness and classical completeness, b) attitude and activeness together have a positive effect on mathematical creative thinking ability, c) The ability to think creatively mathematically in the experimental class students with an average of 81, 21 is better than the control class of 70.82, d) Increased ability of mathematical creative thinking in the device trial class by 61%.
