Learning disability - the story of a definition

This link will lead you to a presentation presenting changes and developments in learning disability definition.  The subject is presented through the stories of three children who are diagnosed differently by the different definitions.  Presented are the DSM5 definition, the Flanagan definition according to the CHC model, the discrepancy formula, RTI and more.

I know not many people are interested in definitions, but I think this is an extremely important subject, having social, political, economical and professional implications.

I've checked and rechecked the information here.  But if you find mistakes, I'd appreciate it if you email me or write a comment.
