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.
If I tend to make excuses for what should be changed in my teaching, I will not be a creative teacher. Here two of Eric Kauffman's high school ceramics students are clay prospecting while on a field trip to a nearby stream on a friend's farm. These students not only made pottery from the clay. They built a kiln and wood fired the pots in the kiln. Experiential learning requires creative processing of what is learned.
