Hi all,
I was researching something on LD and found a 1995 ERIC re-print on teaching strategies for adults with LD. Although it is almost 20 years old, it still includes some universal techniques that may be of interest to you. It can also be downloaded and photocopied at no cost.
ERIC ED381625: Techniques: Working with Adults with Learning Disabilities. (1995)
