Some findings from a recent Rand research study:
Only 31 percent of teachers reported that they have sufficient time to collaborate with other teachers.
Teachers who reported having greater opportunities and time for collaboration consistently reported higher levels of collaboration activity, regardless of the type of collaboration in question.
Peer observation was the least common form of peer collaboration, with 44 percent of teachers reporting that they never observed another teacher’s classroom to get ideas for instruction or to offer feedback in a typical month.
