“The wider the range of possibilities we offer children, the more intense will be their motivations and the richer their experiences. We must widen the range of topics and goals, the types of situations we offer and their degree of structure, the kinds and combinations of resources and materials, and the possible interactions with things, peers, and adults.”

“In a coign of the cliff between lowland and highland,
At the sea-down’s edge between windward and lee,
Walled round with rocks as an inland island,
The ghost of a garden fronts the sea.”
—A.C. (Algernon Charles)
