dh is in a teaching program and he's 41-several people in his program are his age.
that said-dh got his first degree from uop in 2000. he felt the education was good BUT (and i don't know if they've changed their education model since) because it was structured for "working professionals" many of the assignments were structured such that you needed to have the ability to pull in "real life" examples from the field you were studying (so since his was in buisness and computer science he had to take projects or duties he was working on at work and use elements to complete assignments or tasks). i would think it would be hard to have done some of them without access (and some of his classmates who were'nt working in related fields had a difficult time managing this aspect).
he enjoyed the instructors (liked studying from professionals in the field-much more practical/realistic instruction vs. just theory taught from educators who had never/were 20 years out from working in the subject matter they taught).
one of the cons-unlike "traditional" schools, because the classes were made up of "working professionals" who largly were'nt available day hours (and all his classes were nights), when they did group reports/projects (and ALLOT were assigned) they always had to schedual for weekends. so it was very time consuming. another con was the cost-very expensive (don't know how it compares to tuition at traditional schools now but back then it was much higher). also, we were recently surprised to hear that a family member who will be graduating from one of their master's programs in june would have to travel several states from where he lives if he wants to do the graduation ceremony. when dh graduated they did bundle all the local campuses together under the "main campus" for the region in that state but now it almost sounds like they only conduct some kind of regional ceremonies.
check out programs at colleges and universities around you (cuz i have to imagine that even if you can do an on-line program for part of a teaching degree, for the credentialing portion which includes the student teaching you'de have to be physicaly close to a college to facilitate their placement program and oversight). dh looked at several programs and he's opted for one that (if you already have a b.a. or b.s. in one of the disciplines our state requires for a credential) from start to finish is 1 1/2 years (he will take longer because he had to pick up some classes since his degree was'nt one but it was related to one so he's taking the classes to make up the difference). his program will be VERY intense-it's full time begining with summer quarter, with the student teaching begining in the fall and they don't permit outside employment during the 2nd/3rd/4th quarters. at the end of the 4th quarter he will be qualified to teach, and by the end of the 6th he will also have his masters in education (which he needs because although he will be qualified to teach middle school and highschool he realy wants to be able to also teach adults and it's the bare bones minimum for any of the learning institutions around here).
