Como aumentar o respeito aos professores? Interessante artigo de Dan Willingham: * Type I: firing someone who is actually a good teacher. Some of the costs of this error are (1) it hurts the morale of the other teachers in the school by creating an atmosphere of fear, insecurity, and injustice (2) there is one fewer good teacher in the ranks.
* Type II : failing to fire someone who is not competent. Some of the costs of this error are (1) it hurts the morale of teachers by hurting their sense of professionalism; (2) the teacher remains in class, doing a poor job; (3) the teacher damages the professional reputation of all teachers.
Type I and Type II errors trade off. If you want to reduce the chances making Type I error you will be cautious about firing people to be sure you don’t accidentally fire a good teacher. But then you’ll make more Type II errors. If you decide to be less cautious about firing people, the proportion of errors committed reverses. If your diagnostic is imperfect, you’re going to make errors. All you can do is choose the proportion of error .
