I have an education degree, and I found it be nearly worthless. I taught high school French, among other classes. Education courses are necessary, to an extent, and the classes that are included in an education major are NOT that easy, as you state. However, most education classes provided me little assistance in actually teaching. To a great extent either one can teach or one cannot. Everyone is not able to teach. Mere knowledge of the subject matter, while a prerequisite to being a good teacher, is not enough. One must be able to communicate effectively in a way understood by one’s students. One must have a certain amount of patience. One must be able to “connect” with the students. These things come easier to some than to others. I enjoyed teaching, but could not afford to continue doing it and raise a family. I practice law, representing banks and small towns, among others. My teaching experience often comes in handy when trying to convey how the law works in different situations.
My best friend and my s-i-l both said the same thing; they were never taught to teach, but were expected to learn as they go: on the job.
