Amanda Gray, from Learn to be Buddies, is one of my favourite online experts. Amanda is an early childhood, special education teacher who is currently teaching university undergraduates how to develop inclusive teaching practices.
Amanda's blog is full of easy to read, research and evidence based advice for parents and teachers. Amanda encourages readers to interact with her, via the blog and her responses to questions from her readers are as informative as the posts she writes.
Amanda has also developed a set of excellent and very reasonably priced teaching tools which can be purchased through her website.
