Secondly, frequent use of PPT is also a very good method for our teachers. Because teachers have to deal with many things every day. The existence of such a PPT allows teachers to put everything they think into their files, whether it is pictures or tables, or even animations, all kinds of words, all kinds of expressions and the three-dimensional effects that pop up in their first-class brains, which is very rare. It is very difficult for our teachers to rely only on their daily imagination, and we need to do a lot of homework after class, which is likely to fall behind in class. But if we have PPT, we can put it in PPT every day when we think, which is a very good way for us to grow up.
The probability that we frequently use PPT in our daily life is very high. Now, no matter which school or teacher, we are very dependent on PPT. In many universities, teachers are usually equipped with their own multimedia materials. Because of the progress of high technology and some societies, classrooms are basically multimedia classrooms, and each classroom will have various electronic screens. In this case, each of our teachers can give lectures to our students with their own PPT.
However, even though there are many benefits, there are also some negative effects, that is, we have to admit that teachers' excessive dependence on PPT will definitely lead them to leave PPT in the course of future lectures, and they may not know what they want to express.
Because we are lazy when we rely on PPT in our daily life, the same content of a PPT can be taught to different people. Under such circumstances, preparing lessons may lead to all kinds of laziness. Once the school or teacher encounters any unexpected situation, such as multimedia needs maintenance or power failure, our teacher's course may not go on.
