Leaving aside the Sen aspect for the moment.
Take the maths curriculum for example. Most people will never need to do Pythagoras. If you don't you can take a screenshot on your phone and get the correct answer with a higher percentage of accuracy that some people realistically will achieve, and we spend years in school telling people this is essential knowledge. If you need that knowledge in a place of work you will have access to technology that will assist you. Education does not meet reality
We tell kids if you can do your times tables, you wont get anywhere in maths, yet we do now carry a calculator around with us in our pocket that will do times tables quicker than a human in very many cases.
If the goal of education is employability, why are so many university graduates struggling to find work? At no financial premium for having the degree.
If learning for learning sake, why are we forcing kids to do subjects they may never do well in. The ever increasing numbers of kids doing gcse math and English retakes are testament for this
Education is devaluing itself currently because atm it doesn't know what its endgame is. And its failing
When I go to a SENCO in a big successful school and they don't even know that a specialist calculator app for dyscalcula exists, and provision can be made for it to be used in exams, let alone made this standard practice for their kids with dyslexia, its hard not to see how SEN education isn't failing at even the most basic level.
And we are surprised that parents on the coal face are jaded?
