Application and Study on Problem-Based in Computer Network Teaching

Problem-Based Teaching is a teaching method based on problems, in which the teacher combs the knowledge of the course and establishes the chain of questions. So students try to find solutions of them in the learning process. Computer network course is the core course of computer specialty. It involves many knowledge points which is scattered and covering a wide range, so that it is abstract and difficult to understand. Students feel it is difficult to learning because there is no direct link between various protocols. This paper analyzes the existing problems in computer network teaching, puts forward the application of “Problem-Based” interactive teaching mode in computer network course, puts forward that creating problem situation on the basis of theoretical analysis and practice is an effective teaching strategy, and defines the design principles of effective problems. Practice has proved that the application of Problem-Based Teaching method in computer network course can stimulate students' interest in learning, enhance students' self-learning awareness and cultivate students' self-learning ability. This paper takes the “identification protocol” as an example and expounds in detail how to cultivate the students' ability to apply computer network knowledge by creating a series of question chains in computer network teaching.
