I'll be offering Universal and SeaWorld tickets in addition to Disney World tickets. All offer educational programs. You're required to do the Disney and SeaWorld programs if you want the discounted tickets, and the cost is included in the price of the tickets. You won't be required to do the Universal educational tours to get the discounted tickets (but they sound very interesting), and they cost extra.
I'll post more information about them when my Disney webpages go live, but I've been getting questions about both parks so I thought I'd clarify now. You don't have to do Disney in order to do the other parks. (I've separated them out this year.)
