What would an ideal online learning platform look like? 
tokenadult: Perhaps you should contact me off-forum for the long answer. As president of a statewide parent organization for the families of gifted children, I've had occasion to read reviews of, write reviews of, and recommend a great variety of online learning experiences for parents who want to go beyond what is offered by their local school system. My oldest son is an alumnus of distance learning courses from the Center for Talent Development (affiliated with Northwestern University, and I think a Blackboard client), Johns Hopkins University Center for Talented Youth, and Stanford's Education Program for Gifted Youth (EPGY). He is now enrolled in the EPGY Online High Schoolhttp://epgy.stanford.edu/ohs/which has been rolling out implementation of eCollege and PowerSchool for various aspects of school communication to students and parents.Two very crucial things that the part of the market I know still has to get right isa) building student online communities in a way that encourages emotional and social growth of the students,andb) adaptive placement in courses so that able learners can reach a high challenge level and master lots of new materials. Most online courses are too easy and too dumbed-down for the learners I know best.See my profile for how to reach me for follow-up.
