American Sign Language uses embodied actions, manual gestures and facial expressions. Jonathan explains that all of these expressions are crucial in creating a system of grammar for those with speaking disabilities. He mentions that Flash Video clips are crucial for content. I'm not sure how exactly this helps, but in my own experience I have seen this help with autistic and disabled children from my time as a substitute teacher with Atlanta Public Schools.
During my day with an elementary level special needs class I noticed that at times the students could easily work on a task such as math for a few minutes, no longer, before losing interest or becoming frustrated. However, when they were placed in front of a computer and provided a video about math, they were not only immediately engaged, but visibly happier. Having taken this class thus far, I now find that experience even more interesting considering our reading assignment. When other modes of communication were presented to children with learning disabilities the same information that had minutes before been ignored on paper was now, it seemed, being learned and a more full comprehension accomplished.
In our strategy, we need to see where we might be able to add a video or a visual element that may help not only a child, but an adult as well. These children will eventually become adults and will need this type of assistance in the future. Since technical writers are in the business of taking something that is complex and making it simpler and easier to understand, it would behoove us think about this when possible in creating our content. Text only content is boring to most, but with someone who may be suffering from a learning disability it could be almost impossible to understand the material. This would be very frustrating if the content was a necessary part of their daily life.
