Do you really need multimedia to teach?

Once I read a story like this:

There was a teacher trying to calm 30 students. They were not hearing because they were not behaving well. The teacher tried everything, but she didn't calm the students. By that moment, there was an inspector coming to the classroom. When he saw the situation, he told the students "Hey children! How are you? But nobody answered.

Then he said: "I have something very special in my pocket, nobody has seen it before". Then some of the students got interested in knowing about this special thing. One of them asked: "what is it?, can you show it to us?". The man said, "Sure". And then he took a cork out of his pocket. The students said: oh, but that is only a cork". The man said: "yes, but do you know where this cork comes from? No. Well, it comes from Italy, do you know where Italy is? Yes, in Europe. ... Yes, what other country is in Europe?   ... Well, Spain, France, Germany...  Yes, Do you know France?...

Students didn't notice the time was flying while the man was asking and asking questions. The teacher was amazed about what the man did, and she said that she would try to do the same.

After a couple of days, the man happened to come back again to the school, and he decided to visit the classroom of the teacher. But the classroom was the same, a mess. So the man asked the woman what happened. And the teacher said, oh, it is just... I lost the cork, and I can't find it.

Sometimes we depend too much on the tools, on the multimedia, but we haven't changed the way we teach. A boring class. The point is that the tools are changing, evolving. But teachers are not.

Teachers need to be updated.
