Teaching Solid Geometry and Visual Thinking Using Electronic Facilities

Abstract

This study was conducted to investigate the effects of using E-learning facilities in teaching solid geometry and visual thinking to students. The tools used in this educational experience are software including Geogebra and 3D Builder, videos about the real-life uses of geometric concepts, the PDF files of textbooks and the school’s smart facilities. For this purpose, the above tools were presented to 10th grade geometry class, based on educational content and the students’ requirements. In this study, 70 students (includes two 35member classes) where involved whom studied mathematics in a public high school in Tehran’s 3rd District in 2017 and 2018. This experience suggests that the use of electronic tools leads to a better learning process throughout the course. It is a good method to enrich textbook content and offers more accurate illustrations of geometric concepts for students. Repetition and further interaction in this regard are the basis for strengthening the visual thinking of students. In addition, it provides appropriate supplementary content for the use of other students, teachers and even textbook authors. The pursuit of this route ultimately determines the quality of interactive communication between educational content, student, teacher and author of the textbook.
