What children can do with the assistance of others might be in some sense even more indicative of their mental development than what they can do alone

Experience teaches us that thought does not express itself in words, but rather realizes itself in them

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

Writing should be meaningful for children, Y an intrinsic need should be aroused in them, and Y writing should be incorporated into a task that is necessary and relevant.

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

A word devoid of thought is a dead thing, and a thought unembodied in words remains a shadow.

Through others we become ourselves.
