As long as the computer, the mobile phone and the network are owned, the learning can be carried out by surfing the internet, and the learning is not required to be carried out on a fixed saturday or 9 sundays in the morning as in the traditional face-to-face work: 00 to a place far away from home to go to class, the distance education can lead the students to flexibly arrange the learning time according to the needs of the students, completely breaks through various limits of learning on time and place, the students can learn courses at any time and any place through the network, the contradictions of three aspects of work, learning and life are well dealt with, the students really master the self-authority of learning, the trouble of running back and forth of the above tutor is avoided, more time and energy are used for learning, and the learning pleasure is fully enjoyed.
(2) Random arrangement of learning progress
The comprehension ability and the difficulty degree of courses of each student are different, and some students have high comprehension ability and learn faster; some students have poor comprehension ability and learn slowly; some chapters are simpler and may be turned on at all; some chapters are difficult to grasp, and repeated learning may be required. However, the traditional education is fixed and unified in teaching progress, learning characteristics of individual students are difficult to consider, the whole course can not be re-explained again because a certain section of a certain student does not understand, the courseware of remote education is made in advance and placed on the internet, the students want to learn which section and how long the students want to learn can be completely mastered by the students, the familiar students can reduce the learning time and even do not learn, the students can arrange a large amount of time which is difficult to understand, the limitation is completely avoided, and the students can listen repeatedly until the students understand the problem.
(3) Excellent teacher resource sharing
In traditional education, due to the fact that actual teaching conditions and teaching resource conditions of various regions are different, teachers in many remote regions are seriously deficient, good quality is not good, and teachers do not exist in some regions even, so that the progress of local education levels towards high levels is restricted. The network education has the advantages that excellent teachers and resources in China can be gathered together, students in various regions can hear courses taught by famous teachers, and accordingly the overall education level of China is improved.
(4) Extension of AC range
The traditional education is limited by time, space and personnel, the communication among the students is limited to the communication among dozens of students in a class, and the distance education links the students from the five lakes and the four seas together through answering boards, forums, chat rooms and other ways, so that a wider communication space is provided for people.
The network teaching is a learning resource which can provide students with various media, the traditional book learning is mainly realized by describing books, characters and the like in the teaching, the teaching is not vivid enough, is not as clear as the face-to-face explanation of teachers, and is not as good as the learning under the assistance of modern multimedia teaching, the design aims to be separated from the traditional network platform and only emphasizes on courseware, teachers and students' management, the main purpose of the management is convenient and fast operation and convenience, so that students can pay attention to learning instead of being managed, the students become the master of learning, and the subjective activity of the users is improved.
