Developing Ellipse Properties Learning Unit with Computer Assisted Learning through GeoGebra software for Thai High School Students

Abstract

This study aimed to clarify the developing ellipse properties learning with computer assisted learning through GeoGebra software for Thai high school students. Participants include 40 Grade 10 students who were studying in Khon Kaen University Demonstration secondary school, academic year of 2016. Methodology regarded qualitative research. The intervention of Geometry with GeoGebra was provided for semester. The paper will explain how the GeoGebra will be provided for the opportunity students to construct and dynamically visualize geometric figures. GeoGebra builds a dynamic ellipse to show the characteristic of the points that form the ellipse. And, students may find the relation between two points on the ellipse by using GeoGebra. The unit provide students to generate their representation to explain ellipse definition and properties when they on tasks with the GeoGebra.
