多媒体《工程制图》CAI 中的逻辑艺术

Logical Art in Multimedia Engineering Drawing CAI

该文依据在计算机辅助教学（ＣＡＩ）课件制作中的经验，指出ＣＡＩ系统是一种计算机系统，更是一种教学系统。具有教学功能的课件，应能体现一定的教学理论、教学策略、学习理论和ＣＡＩ设计理论。通过对人的思维特点的认真思考及全面训练和培养人的能力出发，以“投影面平行线”及“投影面垂直线”的投影特性的讲解为例，讲述了归纳和演绎的逻辑思维方法的具体运用。

According to the experience of making computer assisted instruction (CAI) courseware, it was pointed out that CAI system is both computer system and teaching system in this paper. To a certain extent, courseware with teaching function should reflect teaching theory, teaching tactics, studying theory and theory of CAI design. In view of human thinking peculiarity as well as overally training and developing human ability, the examples were given to explain the projection's specific property of ‘parallel of projectile face' and ‘vertical of projectile face’ in this paper. It was shown by concretely applying that method of logical thinking of both induction and deduction.
