Third, the teaching media.

Teaching media used in this course: written materials, video materials, online teaching and counseling.

1。 written material

Computer Operating System (2) Wu Enterprise Wanyuan Tsinghua University Publishing House

Note: The main experimental materials of this course.

The main media in the process of compiling teaching materials. The prepared written materials, while maintaining the advanced and scientific nature of the subject system, have realized the ability of integration of the three stresses in the theory and technology of these two operating systems.

2。 Video teaching material

This course has 16 sections and videos, with one section every 50 minutes. It is difficult to concentrate the courses taught and summarize the subjects. In order to help students understand the overall concept and idea of operating system, Professor Wu Qiyuan gave a lecture.

Of course, videos and corresponding written materials pay attention to artistic expression, play video teaching materials and visualize teaching.

3。

Online teaching online teaching guidance and consultation and the function of the above-mentioned organic media: (1) Publish teaching guidance documents, course announcements, consultation and reference materials; (2) According to the teaching progress of the project, an article "Self-test Questions (3) Real-time Q&A, Daily Course Forum Q" published in the psychological consultation chat room; (4) Conduct online teacher training and teaching seminars.

On the basis of written materials, online consultation is an interactive way of teaching and learning that is convenient for students to learn, and it is a supplementary written material for video teaching materials. In short, the division of labor and various media give students more space for autonomous learning, which is conducive to students' free choice and autonomous learning and improves their autonomous learning ability.

Suggestions on teaching arrangements

Of course, some suggestions are put forward on the main teaching materials and the experimental teaching arrangement of the course.

Please arrange courses and face-to-face tutoring according to the requirements of China Central Radio and TV University, as shown in table 1.

V. Teaching methods? Teaching suggestion

(1) Computer operating system is a practical course. It is characterized by many concepts and a wide range. It is required to explain the concept of deep chaos teaching guidance in detail, describe the key points of each chapter and the scheduling algorithm skills of control in detail.

(2) Pay attention to cultivating students' familiarity with the operating system, as well as their ability to analyze problems in maintaining the operating system and solve problems in experiments.

? suggestion

(1) Grasp the learning operating system from both macro and micro perspectives. Macroscopically, we should recognize the position of the operating system in the computer system and make clear the overall structure of the operating system; Microscopically, the operating system should manage computer resources (processes, processors, memories, files, devices) and understand concepts, principles and technologies.

(2) Operating system is a management method of Lenovo's daily life. By combining computer technology and management technology, we can learn familiar sample management and realize the operating system, so as to deepen our understanding of the problem.

(3) We should pay attention to the "learning" culture that strengthens self-learning ability and has the ability to achieve this goal.
