A Psychologically Sound Primary School Mathematics Curriculum

What we know of how children learn has not been applied to the curriculum, with only a few exceptions. Children are given little time to think and to create their own ways. The need to “get inside the child's head,” to understand the kind of thinking done by the child, and to recognize that the child constructs knowledge, rather than accepting it as someone else's construction, must be satisfied before teaching can be useful to the child.
