The Quality Guarantee System Research Of Engineering Drawings Computer Assisted Instruction

With the rapid development of computer technology, all kinds of auxiliary software applications have a great influence for various industries. The use of various computers improves working efficiency and at the same time brings good achievements. In recent years, there have been more students enrolling in the higher vocational school due to its expansion. In order to meet the demand in teaching, they have been universally implemented computer assisted instruction(CAI). In CAI process, we can utilize software making sounds, pictures, animations. But in traditional teaching methods, we have not these advantages. It solved many problems in the process of traditional teaching and greatly improved the teaching quality. With the popularity of the CAI, some existing problems are also gradually revealed. Lots of unqualified courseware appeared in the class. It didn't only arouse students' enthusiasm for study but also let students feel at sea. Some teachers couldn't do well in the CAI. They lost leading position in the course when using courseware and influenced the effect of the multimedia teaching, and so on.This paper tries to study the CAI quality systematically from the point of view of the quality management. The author selected the known course in work Engineering Drawing to survey the multimedia teaching effect. This is a course about geometric illustration and engineering drawing recognition. It is appropriate to choose CAI way to teach the content of the course. The author analyzed and found out the main factors influenced the CAI quality and corresponding solution methods. From the establishment of CAI quality evaluation system, CAI quality standards, CAI team, CAI monitoring systems, the author tried to establish a CAI quality guarantee system. Based on the idea of comprehensive quality management and the goal of serving the students, this paper means to solve today's CAI quality problems.
