Kids are encouraged to share and collaborate throughout the day with value placed on speaking and listening and learning from each other as the teacher facilitates this learning. Some schools have begun to keep statistics on discipline referrals. One large school I have visited has cut discipline referrals more than in half from the year prior to 4-Blocks. They feel accepted by their teachers and by their peers. They learn to be more than tolerant of each other.
Tolerance still has the connotation of division.
4-Blocks kids know that they all have something to share with each other in the classroom. Further, data support that 4-Blocks does not work to the advantage of some kids and to the disadvantage of others. But, again, all kids are winners, academically. Socially speaking, I think that all kids are winners with this model, not just the lower achievers or the at-risk children. I have no idea whether a more equitable environment would have made any impact on the situation in Colorado.
