...but mine was based on "overqualified" being in quotes, meaning not my opinion but the conventional wisdom of people outside of the field of education.
Believe me I'm in the middle of student teaching now and you are absolutely, positively, 100% correct. Nothing I did prepared me for this. I don't know how people do "alternate route" teaching, which in our state means you can just start teaching and get your certification in the process. I just don't see how someone doing that doesn't just get eaten alive in even the 'best' of classrooms.
And I'm someone who has actually made it this far. In my program alone there are 2-3 others who were even more 'successful' in the corporate world, had more degrees than I did and who could not even pass the praxis 2 needed in order to get to student teaching. They went through almost 2 years of the course work and fieldwork and then had to just stop because they couldn't student teach and they ran out of times they were allowed to take it.
Also, personally speaking there is no way I would have been able to do this when I was an undergrad 27 years ago. The only thing that has come close to preparing me for this is having my own kids and dealing with their teachers and the educational system from that perspective.
I'm finishing up in 4 weeks and I feel maybe, just barely ready to go it alone. It's going to be lots of trial and error.
