This NCER Practice Guide is the third in a series of IES guides in education. This guide reflects an expert panel's consensus on some of the most important principles to emerge from research on learning and memory. The guide draws on the best available evidence and expertise to provide teachers with specific strategies for organizing instruction and students' studying of material to facilitate learning and remembering, and for helping students use what they have learned in new situations. The guide includes a set of concrete actions relating to the use of instructional and study time that are applicable to subjects that demand a great deal of content learning, including social studies, science, and mathematics. Along with seven recommendations for teachers, the panel also indicates the quality of evidence that supports each recommendation.
