Hi Anie,
I have found the most effective method of getting instructors ready to go as teachers is practice. I have developed a number of situations and activities that allows the instructors to problem solve and practice their teaching skills. I have them teach min-units of 3 to 5 minutes each using the new techniques on nonsense topics where they focus on the techniques and don't have to worry about the content.
To assist in the understanding of Career College students I have developed profiles and then ask the instructors to create teaching strategies for the unique learning needs of these students. Contained within the activities are methods to assist students with note taking, organizing work tasks, etc.
I ask of the instructors to focus and practice on just one thing that will improve their instruction and then try another. It is immediate use of newly acquired knowledge. They see success and then try something else.
Hope this gives you some ideas. If you have any further questions or want to talk about specific examples please let me know.
Gary
