What does a great education look like?   Is it something attainable, with depth and scope?   Is it an unending cycle of empowerment and self-discovery? What are examples of educational concepts carried out to great success? What are good things for learning alone; and what are good things to learn socially? What are ways for a community of hundreds to learn together over the course of a generation?  What are good things for learning this way?  What are good bodies of knowledge to create this way? Some have suggested that [books] can be a boon to learning, that children and apprentices learn better with them, even when they are working with a teacher or master.   Others say the same about [dynabooks] and [the information superhighway].  What are canonical illustrations or studies of the effects of these (tools|environments)?  What are their advantages and disadvantages?  How fundamental are each to different stages of learning?
