Read an excellent explanation on what it would be far more preferable for our Educational institutions to focus on rather than Knowledge. Found it in Neale Donald Walsch's Conversations with God - Book Two. Excellent reading!
From memory, we are advised to focus our infant and primary education on such subjects as Values, Qualities and various skills that would enable people to see their integral links with one another, Nature, and the world at large.
The gathering of Knowledge (facts and the like) could then be introduced at the High School age when the fundamentals of HOW to live harmoniously have been well integrated into children's minds.
