Problems and shortcomings of video import

. Reasonable and ingenious introduction can make students' distracted attention immediately shift to the classroom, make students in a positive learning state, and promote the smooth completion of teaching tasks: it can realize the natural transition between old and new content, improve the quality of classroom teaching, and optimize the teaching effect.

First, the current problems in the process of classroom import

In the current classroom teaching, some teachers only pay attention to the presentation and review of new knowledge, and lack sufficient understanding of the purpose, function and value of the lead-in link. To sum up, the main problems existing in the import link can be summarized as follows:

One is to copy mechanically. Many teachers will mechanically copy the design of the introduction of famous teachers' classes, without paying attention to the comprehensive ability and actual situation of the students they bring. In the connection between the old and new knowledge, many teachers do not pay attention to it, and directly introduce the famous teacher's class into the classroom, which leads to the poor connection between the old and new knowledge, which in turn leads to the students' inability to review the old and learn the new.

Second, the form of classroom introduction is too single. In the current tutorial, many teachers will take the form of review. In the last new lesson, it is like this every day, and there is nothing new. Teachers often unconsciously repeat teaching after getting familiar with students. In addition, some teachers use games to introduce new lessons, but the choice of games is relatively simple, and they basically use the same games. Over time, students will get bored and gradually lose interest in learning.
