Reuven Feuerstein was an Israeli clinical, developmental, and cognitive psychologist, known for his theory of intelligence which states “it is not ‘fixed’, but rather modifiable”. Feuerstein is recognized for his work in developing the theories and applied systems of structural cognitive modifiability, mediated learning experience, cognitive map, deficient cognitive functions, learning propensity assessment device, instrumental enrichment programs, and shaping modifying environments. These interlocked practices provide educators with the skills and tools to systematically develop students’ cognitive functions and operations to build meta-cognition.
