If a school is seeking to incorporate more collaborative approaches to teaching and learning, the design of the learning environment--whether it's a classroom or a more informal space--can be a critical factor in making this transformative move. Technology, in particular, can play a pivotal role in enabling students to work effectively in teams and in supporting educators as they make the transition from a lecture-oriented to a more facilitative instructional mode. Some schools have spent millions of dollars creating new buildings designed specifically for collaborative learning. Others have invested far less renovating classrooms in older buildings, with the same objectives in mind. While there are logistical differences between these two types of projects, administrators at these institutions say there are key principles associated with outfitting collaborative learning spaces that apply whether one is retrofitting or starting from scratch. The author presents some important high- and low-tech lessons culled from academic leaders who've been part of the design team for collaborative learning spaces.
