When I was on the verge of retiring from the AF, I came perilously close to becoming a high school teacher. My wife worked in the school system in New Mexico and we had many friends from the Superintendent on down to the principals and teachers. They suggested that with my experience, I would be an asset to the school which suffered from a decidedly localized mentality. Few of the teachers had ever left the county let alone the country.
Take a look at this indictment of the educational system of America and the harm of federal involvement in that which traditionally has been a local matter:
No Content in Ed. School Curricula
In New Mexico, I set up an appointment at New Mexico State University's Education Dept. to meet with the chairman. I submitted my resume and work experience along with transcripts of both of my Master's degrees. They were going to work up a curriculum for me to get certified as a teacher in the public schools.
When I talked with the department chair, he displayed the program. Despite already holding a pair of graduate degrees and having formal military classroom and instructional experience including training instructors and course design, I would need an extended program of more than 130 semester hours to get certified! That is equivalent to a full four-year BS degree.
Courses included things like "classroom procedures" even though my work experience included years of platform presentation for technical courses taught to college graduates. There were blocks on "lesson planning" despite my training in Instructional System Development. There were hours of "test administration and design" which seemed to ignore my background creating such tools.
Possibly the worst requirement was the demand that I take "Geography 101." That's when the interview came to an abrupt conclusion. I looked at the professor and suggested that I didn't need to read about those places in a textbook--I'd been to most all of them.
That's what is wrong with teacher education and certification in America. And, it isn't going to change any time soon.
