Advantages and disadvantages of network teaching

First, "Internet? +"Advantages of online teaching

(A) "internet plus" network teaching is an important way for teachers and students to realize non-gathering teaching activities.

"the internet? +"Online teaching activities are low in cost and easy to realize, which is beneficial to both educators and educatees. Generally speaking, you only need the Internet, and at the same time, you can complete the course learning with playing equipment, mobile terminals or multimedia classrooms. At present, what is popular? Various teaching methods, such as SPOC, large-scale open online courses, "online classroom" and "micro-class" video teaching, all have the characteristics of cross-regional, spatial and timeliness, that is, teachers can "teach remotely" and teachers and students can carry out teaching activities efficiently and conveniently without gathering.

The online teaching of "internet plus" is a perfect complement to the regular teaching process.

Schools are institutions that disseminate knowledge, and classrooms are important places to disseminate knowledge, but they are not the only channels for knowledge dissemination. In today's society, the inheritance of cultural knowledge has shown a diversified trend. For example, "micro-lesson" is a kind of "knowledge block" spread through the Internet, with exquisite knowledge and strong pertinence, which can be used as a powerful tool to consolidate the key contents of the classroom. At the same time, because of its small capacity, less network traffic and easy circulation, it is easier to spread on the network and becomes an effective means to supplement extracurricular knowledge.

(=)? Online teaching of "internet plus" can improve classroom teaching efficiency and make effective use of fragmentation time.

"the internet? One of the main features of online teaching is that you can record the screen and store it on your mobile phone or computer for easy retrieval and use at any time. This advantage perfectly makes up for the teacher's need to explain the same important knowledge point repeatedly. When some knowledge points are not fully understood, students can watch videos independently and ponder over the research repeatedly, which will not affect the classroom time of teachers and students, effectively use the effective classroom time and improve the efficiency of classroom teaching. In addition, using mobile terminals such as mobile phones to watch teaching videos can be done anytime and anywhere, so that the fragmented time generated by students waiting for the bus or queuing has the value of efficient use.

Online teaching of "internet plus" is the most potential "tool" for future education equalization.

5G？ The emergence of VR? Upgrading can be closer to the real teaching scene and can effectively reduce the barriers of the screen. Local students can seamlessly connect with the "remote teacher" at the other end of the video, and the teacher can also synchronize the class with the students through the screen video, restoring the real teaching scene, making the interaction between teachers and students smoother, and the feeling of "close at hand" more real and situational. With the development of science and technology. Develop, combine? VR？ By dealing with the details such as the panorama of the podium, the close-up of the teacher's blackboard, the feedback of students' expressions and the close-up of students, the real classroom can be completely simulated and a good classroom can be given to students. Curriculum learning experience can realize the "redistribution" of high-quality teacher resources across regions and effectively realize the balanced development of educational resources.

Second, "Internet? +"Disadvantages of online teaching

(A) "internet plus" network teaching students learning quality is difficult to guarantee.

The current "Internet? +"Online teaching, teachers can not detect students' reactions in time, and it is difficult to achieve effective interaction. This method can't take care of students' feelings, and it doesn't interfere with normal teaching activities. Because teachers' teaching content is preset before teaching, it can't meet the current teaching requirements of "teachers and students teaching together". Teachers and students are more like two independent groups, and the lack of effective communication between them makes the teaching effect greatly reduced and the teaching quality is not high. Although there are questions and answers after class, its timeliness is insufficient, so we still need to learn from the popular "online+offline" teaching mode. It depends on further teaching reform and in-depth improvement of teaching mode.

(B) "internet plus" network teaching requires higher comprehensive quality of teachers.

Education is a highly personalized profession for teachers, and each teacher has his own teaching characteristics and knowledge logic. "the internet? +"In the education era, students will have more detailed questions to consult teachers after consulting materials independently or discussing with more students who are studying online at the same time, which requires teachers to have deeper, higher and broader knowledge literacy.

First, teachers need a broader knowledge system. Teachers should not only prepare their own lessons and handle daily teaching work well, but also read a lot of extracurricular knowledge and accept different forms of knowledge, so as to better handle the dual tasks of local teaching and course answering.

Second, teachers' own learning efficiency should be more efficient. "the internet? In the "+"era, knowledge update exploded, the information generated every day increased exponentially, and professional knowledge changed with each passing day. Teachers are required to make better use of the advantages of the network, update their knowledge in time and improve the latest knowledge structure with the help of the Internet. Only in this way, the increased knowledge can be closely combined with students' interests, and the teaching content can conform to the times, better inspire students to think and promote the development of students' creative thinking.
