Abstract：

The purpose of this research was to look at the role of creative teaching of spatial conception and drawing skills in Engineering Drawing, especially with regard to understanding and drawing "intersections," in order to improve students' spatial ability and engineering drawing skills. In order to achieve the above goals, as to method the researchers did a literature review and used scale tests, experimental teaching and panel discussions. The experimental group used creative computerized teaching materials edited by the researchers and the control group used traditional teaching materials. The research tools were the Intersectional Spatial Ability Scale and Intersectional Achievement Assessments Scale devised by Professor Kang et al (2001). The population for this study was a non-random sampling of second-year students in the Drawing Department of an Industrial Vocational High School. The total number of valid samples was 221. The data was analyzed by ANCOVA and ANOVA, and the main conclusions were as follows:
1.On the Intersection Spatial Ability Scale, the score of the experimental group was significantly higher than that of the control group.
2.Male students tend to have better intersectional spatial ability than female students do.
3.On the Intersection Achievement Assessments Scale, the score of the experimental group was significantly higher than that of the control group.
4.There is no significant difference between males and females on the Intersectional Achievement Assessments Scale.
