The teacher will be informed read and work with the aim of collecting new data developing new topics but also presenting them in new ways. This does not presuppose that those ways that have already been successfully tried will be abandoned but that they will be differentiated and colored differently. Even if the order of presentation is changed tradition can get a new nerve. But even if nothing essentially changes for the students it will still change for the teacher who with renewed desire will breathe life into his lesson with a beneficial end result for the students. There are many ways external to the subject matter being taught that can assist in following a difficult or long course.
The teacher must not only not despise these ways but also cultivate them. For example changing the voice changing position and movement a sudden question to a student not probing changing lighting enhancing a dialogue between students showing an image referring to topics outside e-commerce photo editing the subject matter the use of jokes are often and usual rather tricks of good teachers. When and how they will use them depends on their ability and experience to feel their audience and deal with the belly of the course which after all they need to be there to accentuate the presence of the 'highlights' without which the lesson may be good but not great.
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 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.
