On the basis of using the self-developed instrument for drawing intersecting lines, practical teaching
program, plans and learning evaluation system are made for this teaching method. The preliminary
implementation of this practical teaching method in our school shows that the students’ learning
enthusiasm and interest in learning this difficult content are inspired greatly. Because of the choice of the
exercises and the practical operation by the students themselves, the students can understand the contents
