We belong to TALC (The Alternative Learning Center), which was founded by Katharine Houk.
We have only been there one semester, and so far, we absolutely love it. We are unschoolers, and I am finding it mostly fits in well with our philosophy. However, I don't know of any other members who are unschoolers -- although it's possible they are there. It's just not a big deal there how you homeschool. It's very open.
If you have looked at that website, you probably know how TALC is set up, so I won't get too into it. Let me know if you do want details though.
New families do not have to teach classes, so this upcoming semester will be our first where we are required to do so. I am required to teach, I think, a minimum of four hours. I will be teaching "World Safari," to the 5-8 year olds. I came up with that class because of my children's love of learning about animal habitats around the world. Some of the classes my girls will be taking are on ancient history, the mayflower, dogs, native americans, games, critical thinking, nature walks, singing in harmony, ... There are many more for their age groups alone, and many field trips as well. I signed up for over 21 classes/field trips for my 6-year-old. All classes are what parents choose to teach except that there usually is a gym class each semester (I've actually volunteered to teach the gym class for the younger children).
There are meetings that all parents are welcome to. One can join the steering committee if one likes and volunteer to help in whatever way one feels called to. Families take turns with opening the building in the morning and cleaning and closing after the last class. Classes are twice a week from about 9 to 2.
I really, really love the place, but I'll try to find some cons:
I know that some of the parents of teens have problems because their teens have more freedom within their homes and are subject to more being watched over at TALC.
I know that some families who do more formal schooling are sometimes frustrated that the wide variety of subjects being taught don't necessarily mimic what their children "should" be learning in school that year, so they feel they devote a lot of time to TALC and then still have to spend a lot of time teaching their children at home, and they don't have much free time.
Meetings can be very disorganized and things brought up at the meetings don't always get done. I love collectives, but we could use some more organization.
My only personal problem is not necessarily a problem. I expected to take just a few classes each semester, but my older daughter had other ideas. She wants to take absolutely everything for her age group, so it feels like we are always there. She loves the classes there, which actually makes me question whether unschooling is for us -- although maybe she loves the classes because she knows she is not forced to take them?
The only other negative I can think of is that our location isn't ideal because we are only able to use it those two days, and we can't leave papier mache projects out to dry or make huge models of things that would take weeks, etc. And there are lead issues there and a few other things. But that is a local issue.
As I said, I really love the place, and it was hard for me to come up with these negatives.
