While "blanket bans on screen time may seem comforting, they do not teach judgment, build literacy, or prepare children for the real world." And I support your view that "Instead of reducing technology, we should focus on creating better systems".
I am reminded of the young child at my daughter's birthday party who made herself sick gorging on the sweet stuff, because she was not allowed it at home (therefore had not learned to self-regulate).
My AFIS colleague Craig Jenkinson has been a trailblazer at his school Abbey Gate College with the research, planning, consultation and implementation of their "phone-free" school policy. He puts it really well with a focus on "protection, not prohibition".
Similarly, James Wilding, Head of Claires Court School has done a great deal of pioneering work in this area.
From what I have seen, independent schools, with their propensity and ability to innovate, trial and implement change at pace, are leading the way, and sharing their learning and best practice.
It makes me proud to be part of the independent schooling community, as a parent.
In my recent posts I mirror your thoughts on outright bans and advocate for making the digital environment safer by design, in the same way that safety standards and features are what we expect, and regulate for with regards to physical products and environments.
