Through others we become ourselves.

By giving our students practice in talking with others, we give them frames for thinking on their own.

Any human act that gives rise to something new is referred to as a creative act, regardless of whether what is created is a physical object or some mental or emotional construct that lives within the person who created it and is known only to him.

In play, the child is always behaving beyond his age, above his usual everyday behaviour; in play he is, as it were, a head above himself. Play contains in a concentrated form, as in the focus of a magnifying glass, all developmental tendencies; it is as if the child tries to jump above his usual level.

The child begins to perceive the world not only through his [or her] eyes but also through his [or her] speech

Pedagogy must be oriented not to the yesterday, but to the tomorrow of the child's development. Only then can it call to life in the process of education those processes of development which now lie in the zone of proximal development

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