At present, there are many similarities between interactive teaching in college classrooms and interactive teaching in primary and secondary schools. For example, both of them advocate that teaching serves learning, with students as the main body and teachers as the leading factor. In the specific form, they also adopt the mode of group discussion and centralized display. But the difference between universities and primary and secondary schools is also obvious. First of all, most university teachers are under great pressure of scientific research, and are more busy writing papers and applying for funds, so the time and energy they can devote to research and teaching are far less than those of primary and secondary school teachers; Secondly, there are many teaching contents in universities, so it is difficult to control the progress of interactive teaching. Teachers are always under pressure to complete teaching tasks. In addition, university classes, especially public classes, are often large in scale, and some even have hundreds of students, which undoubtedly brings difficulties to interactive teaching. Therefore, at present, interactive teaching in universities has not completely replaced traditional teaching, and the two often coexist and complement each other. Of course, interactive teaching in universities also has advantages over primary and secondary schools, that is, students are more mature, have stronger learning ability and are more active in thinking.

Compared with the humanities and social sciences department, it is more difficult to carry out interactive teaching in science-because the knowledge of the former is updated faster, the questions are often open-ended, and there is no standard answer, which is just suitable for students to learn and explore independently. Through discussion, exchange and interaction, teachers don't have to know more than students. For example, Professor Wang Yongli mentioned that the famous Harvard Business School is the whole case teaching; The teaching content of the latter is relatively fixed, mostly classical knowledge system, with limited flexibility and standard answer. If students want to interact, teachers should try to extract good questions for students to discuss. The following is the experience of others heard today, including many details in teaching.

You can build a course QQ group to facilitate communication.

QQ group is built instead of WeChat group because it is convenient to answer questions in the group and you need to type on the computer. The advantage of answering questions in the group is that it is convenient for students to ask questions at any time, and it is convenient for teachers to answer the same questions of different students in a unified way. It can encourage students to answer each other and realize the interaction between students. All students can see the questions and answers, which may not have been realized before. Some questions asked by students in private can also be posted in the group if the teacher thinks they are common, as long as the name of the questioner is hidden.

There should not be too many groups, preferably no more than 8 groups, and there should not be too many people in each group. It is better for teachers to designate groups, rather than students to combine freely, otherwise the number of groups will be difficult to control. It is best to have a fixed group all the time, but this requires the teacher to arrange seats for each class. Let the students discuss in groups and answer questions on behalf of them, which can avoid the embarrassment of directly asking students to answer questions but not answering them. Need to design a scoring mechanism to avoid hitchhiking in the group. One way is to score each other in the group, and the low score is naturally a free ride.

Competition mechanism can be introduced, such as giving two groups the same discussion questions.

When group representatives speak, in order to prevent other groups from doing nothing because they are not interested, a question scoring mechanism can be introduced. In the first few classes, students can answer questions by clicking on the monitor, the study committee member, the secretary of the Youth League branch, and the head of the dormitory. These students are generally not very poor students, which can avoid the embarrassment of not being able to answer. Attention should be paid to avoid the whole class being discussed by students in groups, because some teachers are judged as teaching accidents by teaching supervisors.

Interactive teaching also includes emotional interaction between teachers and students, and teachers should have affinity.

The placement teaching mode is a combination of traditional teaching and interactive teaching, which advocates that half the time is taught by teachers and the other half is discussed by students in groups, and at the same time, students should be given time to internalize and absorb knowledge. Specifically, you can discuss the last lecture in the first half of the class and talk about new content in the second half; Or talk about a new lesson and arrange a discussion class, which are staggered. It is said that Fudan University has successfully introduced the split classroom model into the advanced mathematics classroom.
