One of mine is!
My son loved MIT's Splash last year and can't wait to attend this year. Academically minded kids from all over flock to Cambridge to attend classes that range from fun to academically challenging to intellectually stimulating.
I talked it up among our circle of homeschooling friends and about a half dozen kids my son is friends with are attending.
I am thrilled, absolutely thrilled, that MIT has changed the registration procedures for 2010. There is now a lottery system for class enrollment.
For details for this program open to kids in grades 7-12, see the MIT Splash page or follow them on Twitter.
