USING GEOGEBRA IN TEACHING CONES TO DEVELOP THE COMPETENCY USING MATHEMATICAL AIDS AND TOOLS FOR GRADE 9 STUDENTS

This article, based on theoretical and practical research on applying GeoGebra software in teaching cones, aims to highlight the current situation related to teaching cones. This is based on a survey involving 34 mathematics teachers and 63 ninth-grade students. Additionally, the article illustrates the development of a lesson plan for ninth-grade cones, emphasizing the direction of enhancing the students' competency in using tools and mathematical learning resources through integrating GeoGebra software. Building dynamic models using GeoGebra software helps students describe the concept of a cone and the relationship between GeoGebra and real-life situations in ninth grade while enhancing visual and dynamic aspects compared to traditional teaching methods. Furthermore, the article introduces a tool for teachers, which only needs a GeoGebra file with pre-set tools. This tool can be applied for teaching in any location if a computer with GeoGebra software is installed.
