I have very strong feelings on this as you will see...
as an SpLD specialist teacher, I am aware of all themethods used with dyslexics.
The Dore method does not use any new theories- all the man has done (and he is a business man, don't forget) is to promote existing theories, packaged in a very expensive manner.
There has been research around for years that shows that some dyslexics have problems in the brain centred around the cerebellum. There are already books around that parents can use, showing exercises to do at home that stimulate this part of the brain- and that may eventually help with some aspects of dyslexia. This is not new.
There is no cure for dyslexia. All dyslexics need a structured phonics-based teaching programme to improve their literacy.
There are no concrete results for ths Dore porgramme, and the endorsements from ed psychs are not necessarily independent!
The other point is that the staff who administer the program have very little training, and thre are no long term studies of whether it works. It may be that the children respond to the extra focus on their problems, feel more motivated, and their parents also spend more time with them on their reading etc than they did before they started the Dore program.
What worries me most is the cost of thei treatment- if it were so good and offered a lasting "cure" wouldn't anyone who really wanted to help dyslexics want to make it available to as many people as possible for a very small fee- not thousands of pounds?
And finally, this method has not been endorsed by the BDA or any other independent dyslexia researcher.
