Gordon Wells in his book “The meaning makers” (1986):
1. At school, utterances by a child to an adult were 63% less than at home
2. Different types of meaning expressed by children dropped 50% (home to school)3. Conversations initiated by children dropped 64% (home to school)
3. The number of questions raised by children dropped by 70% (home to school)

I often hear teachers complaining about the problems they have with children coming to school from dysfunctional families. I have never heard a teacher talk about the problems families have to deal with from their children coming home from dysfunctional schools. Once again the question of ownership of the learning is central.
