It is very necessary to offer "computer-aided mathematics teaching" in normal universities, which not only adapts to and promotes the new curriculum reform, but also improves the quality of future teachers and meets the needs of educational practice. In the process of teaching with geometric sketchpad, we should analyze the principle of courseware making and clarify the drawing ideas. Close contact with the first-line teaching practice in middle schools; Less theory and more operation to stimulate students' innovative consciousness; Keep pace with the times in the face of new curriculum reform.

1. Foreword: In recent years, China's education reform has been carried out unremittingly, and today's new curriculum reform in primary and secondary schools is in full swing. Nowadays, with the vigorous promotion of quality education, the previous teaching concept and curriculum structure have undergone profound changes. In the application of computer-aided teaching, it is to relieve students' pressure while entertaining. It is also of far-reaching significance to teachers.
