The development of learning tools using treffinger model assisted by geogebra to enhance students’ creativity

Abstract

The development of the Treffinger model learning tools in enhancing the creativity of high school students assisted by GeoGebra software aimed to produce valid, practical and effective mathematics learning tools. This study was development research adopted the development model of Dick and Carey. The subjects were 22 Grade 11 students in one of the Islamic High Schools in Aceh• The data was the validation results and the results of the practical and effectiveness tests. Based on the validity test, the average scores of the lesson plan, student worksheet and test of learning outcome were 3.89, 3.82 and 3.55, respectively, indicating that the tools developed were valid. Based on the results of the pilot test, the practicality criteria were met based on the results of the observer’s assessment of the learning implementation categorized as practical and the mean of the students’ activities also satisfied practical criteria. The effectiveness criteria were also fulfilled based on the scores of the group worksheet and the scores of the student learning outcome test (meeting the minimum criteria of mastery learning). Hence, the learning tools developed were valid, practical and effective.
