The article on motor disabilities posted by Tina Mercer gives a detailed description of the assistive technology tools that can be used to provide people with the independence they need to accomplish tasks at school or work, improve social interaction, communicate, and improve their quality of life. Technology is a miracle that gives these people a reason to wake up each morning.

Adam Seldow, the student from the Harvard Graduate school of education, wrote about social tagging in K-12. On pages 6, 7 and 8 he states that contextual understanding is very important for students who move to the United States from different countries. He seems concerned with the fact that one word, in his example "apples" and how it relates to dentists, can create a situation where both the students and the teacher could end up being correct based on their own perspective of the assignment. It explain what could hapen if the student searches for the tag "apple" on a social bookmarking site. The student might find a tag relating to apples but it might not be the one the teacher was expecting for this assignment. He states that tags reflect an individual's conception of an object (Adam Seldow, page 7). His perspective on tagging was written in April of 2006. Since then many changes have taken place. Although I do not know much about the subject, I can see how using one word to tag an item could have its limitations.
