I'm totally with you on the prerequisite-graph approach for learning. I've been thinking for quite some time about how to best achieve this... Assume the graph of concepts (nodes) and the prerequisites are known (edges)[1]. The system would also have to know (or infer) the current knowledge state of the student. Once this is in place though, you'd be able to type: apt-get learn mechanics and the system will "download" all the prerequisites: functions quadratic-equation calculus calculus mechanics ... To achieve this will require a lot of work: collect existing content, produce new content, organize, create graph (probably need multiple levels: concepts,topics,subjects), create website, etc. There is also an issue with language and level of explanation. You can't use the same language for 6th graders and 1st-year students. So there will be a need for multiple explanations of the same concept. email me if you want to continue discussion... i've got to go back to work now... _____ [1] e.g. http://minireference.com/miniref/lib/tpl/miniref/landings/images/concept_map_light.png http://minireference.com/miniref/lib/tpl/miniref/landings/im...
