Professor Feuerstein spent many years working with children surviving the Holocaust whom teachers and psychologists had declared “unteachable”. For them and because of them he developed his well-known “content free” mediated learning techniques that are more and more used in helping to children suffering by cultural deprivation, students with special needs, children struggling to learn, as well as adults. The children are guided through one problem after another as they build their own repertoire of metacognitive strategies and head towards independence.
