How fortunate that Mr. Cullum had a talented friend in Robert Downey, Sr. who was skillful and sensitive to the magical moments fostered by an inspired teacher. The old black & white clips still capture the thrill children feel, when allowed to interpret information and learn from each other, while being guided by a teacher who wanted the very best for each of them.
The reunion at Rye, NY with some of his early students provided a thoughtful analysis of what his methods meant to them, and how they prospered under his tutelage.
I recommend that elementary & middle school teachers show this DVD at least once every year. It's that inspiring.
