The National Academy of Sciences commissioned a report on How People Learn which is now being used by a wide range of educators and researchers. The report provides a review of critical research on human cognition that has informed the development of pedagogical methods that lead to learning. The report evaluated a large number of effective learning environments ranging from early childhood to adult education and identifies four central dimensions common to all of these. These dimensions include: knowledge, learners, assessment and community. This online presentation provides a brief overview of this framework and some of the characteristics that define each dimension. This framework is a method organizing an evaluation or design of a learning experiences that will result in high impact learning outcomes (impact in acquired knowledge, number of learning objectives, efficiency of instruction and quantity of learners participating in a learning experience).
