My son started Reception in September 2023 when he just turned four and so far I feel the system of rewards (stars, certificates) is not quite appropriate and disorientating for such young children. I have recently come across Alphie Kohn books (e.g. Punished by Rewards) and Gordon Neufeld theory of attachment. I think their approach would be more appropriate especially for very young children.
I must explain why I think rewards are not working for young children.
In YR they have children who turned 4 just before the school year started and others who turned 5 shortly after they started YR. At this age the gap in development is huge. I remember in October or November the teachers were giving certificate to a 5 year old pupil for writing word "meatballs" when my 4 year old still did not have a proper pencil grip. He is still not able to blend phonics even though he knows and can pronounce all of those they were taught so far.
Another thing I noticed my son makes attempts at homework, like trying to read, with the thought to get praised by teacher. I am trying to explain that he needs to learn to read because it is the skill required for everyday life and not for getting stars and certificate.
I wonder if there are any primary schools (state or private) in SW London that use no rewards/no punishments approach and try to motivate young children with the process of learning.
