A link to what we know about planning learning spaces and what we need to know. Those involved with the Learning Spaces Collaboratory (LSC) are collaborating in translating findings from contemporary research and practice in the field into roadmaps for shaping and assessing built environments for learning in the undergraduate setting. Collaborating partners within the LSC, including academics, architects, leaders of national societies, and academic leaders across the country, share a commitment to transforming the learning environment for undergraduates in all fields. They also recognize that the quality and character of the physical environment for learning matters to the quality and character of the learning experience for all undergraduates. This is a collaborating community of researchers, practitioners and other stakeholders developing resources to inform the practice and process of planning, experiencing, and assessing 21st century learning spaces on campuses across the country.
