I teach for a unique arts program at a university - I have classes of children from public school as well as homeschool classes. I have to admit I was a bit skeptical before I taught my first class with homeschoolers (about two years ago), but have since changed my tune. Most of the homeschool parents I have personally encountered are very highly educated, and they are very organized. Many have formed regular subject-specific study groups and seek out the best community resources. Some of my students are currently at a national homeschool sports conference. I think, if done correctly, it is a viable option. The parents on this thread seem like the kind who are very responsible and resourceful in their home education.
I like my homeschool classes because they are generally very serious students who will take notes on the art historical period, artist, vocabulary words (without complaint), and come to class prepared and eager to learn. I allow them to arrange their own still-life setups in groups because they work well in small cooperative groups. My only concern, sometimes, is them becoming accustomed to a traditional classroom setting when they come to do more structured activities, and when they go to college. Some of my particular students are so accustomed to conversing with adults (and more informal learning environments) that they have to be gently reminded not to interrupt and talk over me while I am demonstrating, sharing, instructing. Overall, though; I think that it is possible that homeschooling could provide just the right blend of structured and unstructured play times. I agree with some of the above comments that so many kids just don't seem to have time to just play - especially outside. I am so happy to teach art to children but am saddened when some have been in school all day, come to art class, then go straight to tennis and gymnastics, then homework and projects, etc. etc....
I also think there are so many wonderful schools and teachers. So much of public school is what you make of it, and depends on supportive involvement of active parents. There are advantages and disadvantages related to either choice. I have many good public school students whom have obviously had excellent instruction. And most of my family are dedicated public school educators whom I am really proud of.
Anyway, my two cents worth.....
