The arrival of the information age, on the one hand, makes our education face severe challenges today; On the other hand, it also creates good opportunities for the further development of education. In meeting challenges and developing education in the information age, online education will play its unique role with its unique ideas, ideas, means and methods. Times have branded all aspects of society with the network, and so has education. The establishment of education network and campus network provides great convenience for people to retrieve documents and academic exchanges. So, how will online courses change the traditional teaching methods? Will it bring some negative effects while developing? How to give full play to its advantages in online education construction? On personal views. First, the potential advantages of online education. Modern society requires education to realize two major changes in its own development process: from exam-oriented education to quality education; The transformation from school education to self-education and lifelong education. Obviously, traditional classroom teaching is difficult to adapt to such changes. Traditional classroom teaching has a single expression, and spoon-feeding teaching restricts students' subjective thinking activities; The plane expression and simple language explanation of objective things often make students' imagination deviate. Network education adopts diversified teaching forms, transmits text, graphics, sound, animation and video information through multimedia means, and combines the real world with virtual reality, which accelerates the understanding of learning content, stimulates brain excitement and continuously strengthens memory. From the perspective of educational psychology, online education has the following advantages. 1, cultivate students' autonomous learning ability. Through the study of online courses, students and teachers are separated, and the learning process is completely realized through students' independent activities. We must consciously restrain individual behavior and design our own learning process (online courses make learning suggestions through interaction) until we reach our learning goals. The learning process is carried out in a state of active thinking, strong interest and inspiration from generate. Through this way of learning, students cultivate the ability of self-management and self-discipline. 2. Develop students' personality. Distance learning can flexibly control the time, without any restrictions, as long as it has basic internet access conditions. The learning process is from individual behavior (introductory stage) to group behavior (discussion stage), and then to individual behavior (self-test). Compared with the traditional learning process-group behavior (teacher's teaching stage) to individual behavior (homework test), it highlights the role of individuals. This process is not a simple form change, but creates conditions for personalized quality education. Highlighting individuality means personal innovation, and the flexibility of thinking and novelty of thinking expression brought about by it are beyond the reach of traditional teaching methods. Traditional teaching methods make middle school students' thinking activities subject to teachers' knowledge construction and achieve the same thinking goal. Facing the structure of organic connection, the students of online courses have realized the idea of seeking differences. This is undoubtedly in line with the requirements of today's society for talents. 3. The improvement of students' cooperative spirit. The interactivity of online courses enables students to break through the geographical and time constraints, participate in the communication between students and teachers equally, avoid the phenomenon that some introverted students are ashamed to speak, and enhance the flexibility of collaborative learning. The expansion of the communication area enables students to learn the strengths of others in a wider range. The diversification of interactive ways stimulates the interest of participation, so that the learning process is always carried out in an excited mood. 4. It is conducive to students' lifelong learning. With the accelerating development of science and technology, the expansion of knowledge and the emergence of interdisciplinary subjects, everyone is faced with the need to meet the requirements of social talents, and everyone is faced with the era of constantly supplementing and updating knowledge. Regardless of personal wishes, lifelong learning is necessary. With its advantages of cross-region, cross-culture and cross-time, online education meets people's requirements of learning knowledge at any time to the greatest extent, which is incomparable to any form of education. Second, the problems existing in online education At present, online education in China is in its infancy, and there are still some problems to be solved urgently. 1, online courses lack emotional communication. In the traditional teaching method, there is potential emotional communication when teachers and students communicate face to face. Teachers can infect students with their unique personality charm, so that students can learn a lot of things besides books while learning knowledge. In particular, some excellent teachers' humorous teaching forms can not only stimulate students' strong interest in learning, but also deepen their memories and make them unforgettable. When using online courses to study, students are faced with an indifferent object. How to endow these objective materials with rich emotional communication ability puts forward higher technical requirements for the construction of online courses. 2. Autism brought by online courses. The learning environment of online courses is a relatively autistic environment. Pure online learning is to communicate with each other through a set of network equipment, which virtually reduces direct contact with the crowd. Although the network can show the whole world in it, it is a world after all, and it should be admitted that it can completely replace reality. Therefore, we should organically combine online courses with other learning methods, and give full play to the advantages of each method, so as not to isolate the connection between individuals and groups while using online autonomous learning. 3. Other side effects brought by online courses. First of all, the study of online courses is prone to fatigue. Facing the fixed machine, staring at the screen for a long time will bring visual fatigue; When using the terminal, the fixed body, posture and sometimes boring learning content not only affect the learning effect, but also are often the main reasons why people give up online learning. This requires the designers of network equipment to consider from many aspects, and the designers of network courses should also pay special attention to the diversity of design. Secondly, people have become accustomed to the traditional listening and thinking in class, which will cause resistance to online course learning. Although multimedia courseware has rich means of expression, people also need a process of adaptation and acceptance. Third, the construction of online courses At present, although there are many problems in online courses in China, they have shown great vitality. Builders make full use of all kinds of organic integration of online courses and make them as perfect as possible. It needs to be further improved in the following aspects: 1, the construction of multimedia courseware. The core of developing online courses is the development of multimedia courseware, which mainly includes the selection of content, the arrangement of knowledge points and the processing of man-machine interface. How to make the interface more pleasing to the eye without usurping the host role; What kind of color matching can fully satisfy the user's attention and help him think and remember; These problems require developers to think more from the physiological and psychological perspectives. 2. The development of online interaction ability. Online interaction is a means to endow machines with emotion. Therefore, interaction design should be as anthropomorphic as possible. At present, various intelligent designs, such as intelligent answering system, intelligent testing system and intelligent learning system, make learners feel that they are facing a knowledgeable expert. 3. The cultivation of teachers' quality in online courses. The requirements of online courses are not reduced but improved. The development of online courses should focus on excellent teachers and integrate their unique teaching methods and means into the network, which requires these teachers to have certain network development ability and master the necessary development tools. When conducting online courses, we can't completely abandon the traditional way and communicate with students face to face according to the needs of realization. The online course has the function of real-time updating. Teachers should keep abreast of the latest development of the subject, modify and supplement the online course in time, and strengthen their teaching ability.
