I know Colorado College calls it the "block plan" so its possible it will bring up results but like I said, Colorado College and Cornell College are pretty much the only ones. Are you looking for anything in particular?
Evergreen College in Washington. I hadn't heard of it until I met someone who went there. I'm looking an educational environment like this. Have any other ones been found since '05 ?
Thanks
1. University of Montana Western
2. Tusculum College (in Tennessee)
are two more of the total of four colleges operating on a block schedule, according to Wikipedia.
