Maria Serpa, Ph.D. has designed a very comprehensive site with recommendations, readings, and comparison sheets regarding language differences versus learning disabilities. She includes recommendations for assessment practices and her professional opinions regarding standardized testing. She also has a section with readings on immigration patterns and special educations law and resources. Finally, she has a very nice section on differences between spanish speakers and the differences that they may bring to the English language learning process in respect to phonological awareness, grammatical influences, semantic influences, pragmatic contexts, and written language. Enjoy!
