According to this post, "A new report from the National Academies of Sciences, Engineering, and Medicine highlights the dynamic process of learning throughout the life span." It looks pretty interesting. It's available here - you have to log in to download the PDF (grr) or you can read the 347 pages for free online. "Learning is an ongoing process that is simultaneously biological and cultural. Each individual learner functions within a complex developmental, cognitive, physical, social, and cultural system. Learning also changes the brain throughout the life span. At the same time, the brain develops in ways that impact learning and are in turn shaped by the learner’s context and cultural influences." There is much much more.
