“微机原理”的案例教学——交通灯控制问题

《微机原理》不再仅是计算机专业的基础课,同时也是其他工科专业的重要课程,它可以培养学生的硬件开发能力。但是非计算机专业的学生对这门课程重视不够,加上课程本身比较抽象,就会使学生产生厌学情绪。本文以交通灯控制问题为例来讲述8255A的相关知识,收到了很好的效果。从而说明案例教学法的重要性。

The microcomputer principle is no longer only a basic course for computer science, but also an important course for other engineering majors. It can cultivate students’ ability of hardware development. But students who are not computer majors will not pay enough attention to this course, and the curriculum itself is more abstract, which will cause students to become bored. This paper, taking the traffic light control problem as an example to tell the related knowledge of 8255 A, has received a good result. This explains the importance of case teaching.
