The analogy with the theater seems to haunt me since again I think that perhaps the actor also gets tired of repeating the same performances and needs similar findings to vary his performance and to communicate with the audience. It is true that there are good and bad classes just as there are good and bad shows. And I am referring to the same course with the same composition and theme as well as the same play with the same theater group. This is due to both the teacher and the students. Because a good teacher can be enough for a good lesson. But a great lesson needs a great teacher but also great students.
Because only their dialogue will advance the discussion to limits that will force the teacher to touch his own limits. After all it is equally common for both the teacher and the students to one day for specific or unknown reasons photo background removing have a reduced enthusiasm for their participation in the lesson. And this is comforting since it shows that for either side the lesson is not a typically repetitive process. I prefer maybe and forgive my liberality of simile homemade sweets. Sometimes they fail but often they are great. While the patisseries sweets are distinguished by their scientifically repeatable mediocrity.
Breaks usually minutes within a long lesson are another thing that is needed for various reasons. First of all it strengthens the contact between the students but also encourages personal contact with the teacher to whom questions are submitted by students who often for reasons of agoraphobia did not submit during the lesson. In this last case the teacher can bring these questions before the group in order to promote the dialogue thereby bringing the specific student out of isolation. Student participation in the course dialogue is essential. he will allow students to participate. And the teacher is confident when he can admit his ignorance but also support personal opinions.
