The myriad of formal rules and procedures and informal routines and customs are unclear to the beginning teacher. Think about how the new teacher feels. I know I have. Teacher isolation is especially traumatic for new teachers. Veteran teachers often don t assist for fear of interfering.
Novices don t ask for help for fear of seeming incompetent.
In many cases there is a conflict between being teachers and young adults. It is their first job, they are away from home for the first time, they need a new car and apartment and doctor. Problems arise and the new teachers don t have adequate time to give to either the professional or the personal role. The new teachers want to change the world. They can t even make it through the roll.
