I've never taught K-12. I've never had a long absence (a week max..), or - at least one that wasn't planned into the syllabus -- like when I took a long time for debate nationals...
So, having a colleague teach my classes is a new experience for me.
It's required me to openly discuss my teaching methods, my class' abilities etc.
What's kind of odd about it, is that I'm still doing all the grading. I'm still the one who handles all the problems etc.. they are the ones conducting the classes I've planned.
The results will be interesting, to say the least. In Logic I'll give an exam my first week back -- so, my subs will do the teaching of the material and I'll be doing the assessment.
In Ethics, my sub is starting conversations on topics -- and I'll be evaluating their understanding of the topic in essay questions.
I'm really lucky to have fantastic colleagues who will help me out -- and it's quite fortunate that we didn't follow our old dean's requirements for scheduling -- (she wanted us all on campus 5 days/week...), as this only works because my logic subs are off T/Th... when all THREE of my logic classes meet.
