There is something very weird about teaching in this country.
'Creativity' is valued above all else. They are expected to re-invent the wheel every lesson rather than follow anybody else's plans.
I don't know why this culture exists. I presume it's just the pendulum swinging too far in one direction.
However, what it means, is that every teacher up and down the country is inventing their own lesson every day for teaching kids to read. Their main (but not only) complaint about schemes like Read, Write, Inc is they tell them what to do!
While teachers believe 'following plans' is bad and 'making it up myself' is good, you have the situation we're in now where there are many, many, many effective schemes, including free govt ones explaining how to teach kids to read - and the teachers just won't follow them.
So, yes ITT needs to improve. Dramatically. (Not only for phonics, but also for SEN :) ) - but also the attitude they are teaching needs to change. Their needs to be more of a balance between coming up with ideas which will suit your individual class - and following proven methods.
