Also, their journal must include some critical thinking about the pros and cons of another way of teaching. It is fairly easy for apprentice teachers to learn by imitating their model teachers. However, creative teachers go beyond their own teachers. They go beyond their mentors. They do this by virtue of their own critical review of their own teaching by carefully reviewing what happens and then searching for alternative things to try.
Creative teachers make mistakes, but but they also search for ways to overcome mistakes.
Each time they try something, they review the outcomes and try to imagine ways to make improvements. If I am an uncreative teacher, I do not feel that I make mistakes. I may admit to some bad outcomes, but in my uncreative mind students are to blame for bad outcomes. I say, Nobody can teach correctly for every student in a class and certainly I should not be held responsible for an unmotivated or mentally challenged student. Students have to do their part.
