The problem with transitioning into teaching is four years of a teaching degree that costs money and is useless for anything else.
When I went to college many years ago, the college I attended had a teaching degree program. The courses from that program were not interchangeable with those from any other degree program.
I have my degree in meteorology and have had science courses at the college level in everything except geology. These were courses specifically required for science majors so were generally recognized as more rigorous that the teaching major science courses. Yet they will not transfer into a teaching degree program.
I would not be interested in going through four years of college again, taking and paying for courses I would learn nothing from.
There likely would be plenty of well qualified teachers available if there were some way of taking a short make up type of course, that would touch on those subjects necessary for teaching, while letting the rest of the education or practical work experience count for something.
The thing that always blows me away is that a person is not allowed to teach public school without a teaching degree, yet the college professors who may not have a teaching degree, teach teaching majors. So the profs are qualified to teach the future teachers but not the students the teachers would be teaching. They can teach college but not high school or less.
Four years? No, the transition to teaching program here at Ball State takes two semesters and one summer term. That’s not even a year. And it costs $4,500. That’s not bad at all.
