What a child can do today with assistance, she will be able to do by herself tomorrow.

There is reason to believe that voluntary activity, more than highly developed intellect, distinguishes humans from the animals which stand closest to them.

A child’s greatest achievements are possible in play, achievements that tomorrow will become her basic level of real action.

The specifically human capacity for language enables children to provide for auxiliary tools in the solution of difficult tasks, to overcome impulsive action, to plan a solution to a problem prior to its execution, and to master their own behavior.

The teacher must adopt the role of facilitator not content provider.

The only 'good' learning is that which is in advance of development.

Through others we become ourselves.
