This document discusses Basil Bernstein's theory of cultural deprivation and language codes as it relates to class differences in education. It can be summarized as follows: 1. Bernstein proposed that working class children experience cultural deprivation that limits their intellectual development and language skills compared to middle class children. 2. He identified two main language codes - restricted code used by working class families and elaborated code used by middle class families and schools. 3. Bernstein argued that schools reward the use of elaborated code, putting working class children at a disadvantage if they only have access to restricted code in their home environment.
