Abstract: In this paper, a new method of multiple practice teaching reform for product mapping course is
presented. It includes four aspects as follow. First, introduce 3D CAD technology to built modelling and
detail drawing to replace ruler gauge drawing and to keep product disassembly, surveying in product
mapping and freehand sketch drawing of parts and assembly. Then students’s innovation consciousness is
improved by reducing redundant rules, increasing autonomous choice and stimulating students’ interest. Next,
it is to improve students ‘consciousness of team cooperation and students’ oral communication and writing
skills of the technical document. Last one is an evaluation mechanism which all students have right for
participation. At the same time, secondary development for 3D CAD software is finished for preventing
electronic homework plagiarism. A teaching practise for 7 years has proved that the multiple practise
teaching reform can stimulate students’ interests and creativity which laid a foundation for later courses.

Key words: individual interests, product mapping, practice course, teaching reform
