People that strive towards social justice are those who believe in participation, pluralism, and liberation. It has already been argued that participation is necessary for success. Pluralism is evident in the cooperation of the students and teacher. Within this is the recognition of each person's worth in participating in the culture. In this system, everyone is gifted and talented.
Every person has a mode of self-expression in which they feel success.
This makes them an important member of the pluralistic society of the classroom. It can't be proven that they are learning anything. Children need to play and should play in school. It is implied here that children should not be able to experience the same kind of joy they feel from play in their schooling. This is what a formal classroom is based on with its rigid structure of rows of desks, discipline in the autocratic omniscient teacher, and time-based scheduling.
