My son attends Connections Academy, and when folks ask me about his "homeschooling" I try to correct their impression: yes, he's home, but he's doing virtual school. They have the whole curriculum planned out, he has a teacher for each subject, assignments he must submit, etc.
I have certain flexibility as far as what additional work I require (other than submitted assignments) and *when* he does the work, but that's about it. Waaayyy different than homeschooling.
