A central goal of the PKAL Learning Spaces Collaboratory is to imagine a future in which the process of planning learning spaces is informed by both theory and practice. A key first strategy to realize that goal is to identify salient research, from scholars in a perse range of fields, which has unmistakable implications for planning physical learning environments for undergraduates in our nation’s colleges and universities. A complementary strategy, as the research is captured and reviewed, is to develop a feedback loop between theory and practice. To catalyze this feedback loop, we will capture and post papers from the community of theorists and the community of practitioners. Annotated contributions and other suggestions are welcome.
