The usual way to make sure that teachers do their job well is by observing them, by having the principal or the coordinator or some other supervisor observe and then sit them down and tell them all the terrible things that they did wrong, possibly reporting them to whatever authorities might be able to enforece this. In other words, terrifying the teacher. Supposedly this is the way to improve performance.

It is questionable whether it will achieve its goal. More likely, the teachers will just leave the profession based upon it.

A beginning teacher with a great deal of potential is likely to be intimidated by visits which create an artificial atmosphere in the classroom and which creates fear of repercussions as a result.

It would be far better if the observations would be kept to a minimum as a means of improving the quality of the leadership.

Instead of depending on that method, perhaps it would be better to instruct the teachers in methods of improving the quality of their education.

Teachers usually like to teach well. That is why they went into the profession in the first place. Help them succeed rather than criticizing their lack of success.

This method would be far more effective and would result in better teachers.
