Deanna,
Like you, I became a career college instructor without formal education in teaching. I felt comfortable and competent with the subjects I was teaching because it was my career for 25 years. But, I was unprepared for all the other activities involved in preparation, delivery, organization, etc. It was quite refreshing to find out that I was already applying some of the things in ED101 in the classroom. This course also gave me better insight on handling students individually and as a group.
