Don’t worry about taking this in a new direction as I already got lots of suggestions about places to look and styles I had not considered.
My situation is not the average student’s experience. I’ve been working with this high school for a while as a certified substitute, and I’ve already completed my degree, I was just getting certification to teach. The principal knows me personally and he was even my instructor for the content area of methods. I taught summer school for him this year too. He was confident enough in my abilities to ask me to do this as a favor. Most of the teachers in this building know me, and I feel comfortable going to just abut any them for advise. I think the science dept chair and the principal will be frequenting my classroom when they have time, to make sure I’m keeping things up to snuff. I am covered legally by insurance through SMSTA just like all other student teachers and by the fact I’m a sub for the school. I assure you, this practice is perfectly legal and not uncommon. There are many instances of students having their first bit of teaching count as their student teaching semester. The only catch is the education department at their university has to sign off saying it’s ok. Surprisingly enough, the chair we’ve been talking about here signed off for me, although it was because I was going to fill in for one of her former “favorite” students while he’s away on active duty.
There are lots of things wrong with my college’s education department, but this is one instance where they have done things right. The small high school in a small town would be hard pressed to find a sub to cover a lady’s maternity leave as qualified in the sciences as I am. Honestly, the only person they could find to work for the guy I was originally going to cover for is a guy majoring in social sciences. Those poor kids got almost nothing out of the last half of the school year other than powerpoints and lots of naps. When I was there subing, several good students would regularly come find me and ask me to explain assignments or concepts he brought up in lecture. In one particular instance, they barely understood the concept of a basic monohybrid cross, let alone how to represent it on a punnett square

and bring up a dihybrid cross and they looked like this
