It is not just what students know, but how we can create future learning. Propensity is a power or force which propels an individual into higher levels of functioning. It involves a willingness to be modified. Propensity may exist in different individuals at different stages. Reuven Feuerstein CNILDLndn

We are not attempting to raise a student's IQ, rather we are raising his propensity in order for him to function more effectively.
