With the rapid development of information technology, computers have penetrated into all aspects of our lives and played a huge role. From primary school to university, almost every school-age stage has corresponding computer courses. Compared with other disciplines, computer science has great particularity, which is not only practical, but also fast in updating knowledge points.

First, according to the actual situation of the school and students, choose the teaching content reasonably.

The existing computer textbooks rarely consider the differences among regions, students' knowledge and school experimental equipment. Therefore, teachers should first make a reasonable choice of the knowledge points in the textbook, select the essence and key points, and avoid covering everything. This is obviously different from other disciplines such as mathematics, physics and chemistry. Other disciplines, such as mathematics, physics and chemistry, emphasize the comprehensiveness of knowledge points and the interrelationship between knowledge points, while computers, as a tool, focus on a certain application, and the knowledge points involved in various applications are relatively independent and have little relevance.

This paper is quoted from the magazine, which is a Chinese computer-level advanced academic journal published at home and abroad by the head of the Ministry of Industry and Information Technology of the People's Republic of China and sponsored by North China Institute of Computing Technology. It is the journal of China Computer Federation, which was changed from bimonthly to monthly in 20 10, with publication number 16. Welcome to contribute (both in Chinese and English). Coverage: Insist on publishing innovative, cutting-edge, instructive, pioneering and exploratory scientific research achievements in the field of computer (hardware and software).

Therefore, there is a lot of room for us to choose the knowledge points of computer specialty. We can comprehensively consider the practicality of knowledge points, students' acceptance, school experimental equipment and social needs. And we should avoid completely copying the teaching materials, otherwise students will not be able to master the knowledge points well because there are too many knowledge points, which are too difficult, and the experimental equipment does not support them, or it is useless to master them.

Second, "task-based teaching" throughout the classroom

At present, the task-driven teaching mode is often said that teachers design the teaching content into one or more specific tasks, so that students can master the teaching content by completing a specific task and achieve the teaching goal. The advantages of "task-based teaching" are: as long as the "task" is put forward, students will have a strong thirst for knowledge; Students have typical examples to refer to when learning knowledge points, which are both profound and easy to understand; When completing the "task", you can deepen your understanding of knowledge points and help cultivate your practical ability. For example, in the teaching of programming, when teaching the chapter of window communication protocol, I first assigned a "task" to students: designing an online chat system. As soon as the "task" is put forward, students' interest is very high.
