Diversity of individuals is definite, though might be oppressed. It is no use to be afraid that education/instruction would kill individuality.
Indeed, diversity cannot appear over nothing/empty. Materials must be given. In the case of couse/class design (as organization design), sound learning subjects are the most important materials where students' diverse individualities becomes present, released and activated.
In fact, diversity of individuals is just a if-then condition. The better 'if' content (that is, the given) is, the better 'then' content (that is, quality of diversity) is. The author knows by experience that the most important at course/class design is 'making students learn basics steadily'.
Organization design is to prepare/realize an adequate ground/opportunity where the diversity of individuals becomes present/released/activated. And, as the author proposed, today's one of the most promising solution is the 'web-based'. We are still far from making the most of it.
