This is part 2 of my response to Dr. Martin’s answer to my question.
As you read this, please ask yourself what happened to this research 'Children of the Code' which was conducted over 13 years.
David Boulton:
10 times the number of kids who have innately biologically ordered learning difficulties have learning difficulties that are a consequence of what they learned…... Until such time we can read that they are cognitively going askew relative to what they have learnt in the past then our teaching is kind of brute force against this deep core stuff that is working against us.
How much of what they are struggling with is an innate learning problem and how much of what they are struggling with is what they have learned in the past working against them learning now.
