The Asperger Syndrome hyper-focusing trait can be helpful in a classroom setting when educators choose to use this extreme attention span as a tool.
If normal classroom learning procedures are not getting through to an AS child, try working with the theme that they are already working with. As an example, a few words about their chosen object mentioned during a history lesson, can perhaps make the entire history lesson memorable.
the Asperger Syndrome hyper-focus ability is a learning style. AS children have the ability to hyper-focus their way into learning traditional subjects.
