“…Practice question sets for students to practice in their spare time, so that they can have a deeper understanding of what they have learned; 4) Reference answers for students to refer to after practicing, so that they can understand what they have done wrong and where they have gone wrong; 5) Online testing and automatic scoring system for examination papers, which has a randomized database of examination papers, and the topics of the papers are different for each time, but the examination papers are the same in terms of types of topics and difficulty, and the examination papers are also scored by automatic judging after finishing the examination papers, so that the students can understand what is still insufficient for them; 6) Animation demonstration, some of the more abstract issues, the form of animation to show the abstract problem specific, image, intuitive display to the students, so that the content of the teaching is more easily understood and accepted by students; 7) Computer communication and network teaching case library, including from the actual construction of the project extracted from the relevant computer communication and network engineering cases, the students through the study of engineering teaching cases, can more deeply appreciate the relevant computer communication and network engineering cases, the students will be able to learn more about the project teaching cases, the students will be able to learn more deeply about the project teaching cases. The students, through studying the engineering teaching cases, can more deeply appreciate the application of related computer communication and network technology in the actual engineering; 8) Course-related new technology lectures collection, we organize the course team teachers, some of the latest advances in computer communication and network technology, in the form of academic presentations, introduced to the students, so that the students are up-to-date with the latest technological advances related to the course, and keep up to date with the latest developments in the relevant technology [16][17][18].…”
