You asked about books I've used to educate myself. That's a harder question than it sounds. I've read a large variety of books, but I've also read articles, read websites, followed links, etc. I think what happens overall is that I pick up a little knowledge here, and a little knowledge there, without even quite realizing I've done it.
The places I've probably learned the most are:
* the training for using Wilson materials (Orton-Gillingham based)
* Overcoming Dyslexia by Sally Shaywitz
* books by Diane McGuinness
* The ABC's and All Their Tricks by Margaret Bishop
* anything written by Louisa Moats
* the Phonics Pathways website and newsletter
* and especially anything written by or suggested by Palisadesk. I'm in awe of her knowledge base.
As to that last item: me, too!
