I will continue my exploration in the web usability. According to Nielsen (1997) in his research on how people read website, there are only 16% read a website word by word and 79 % of people just scan the web page. Thus the web site contents should be well structured and clearly written, inevitably sighted students with cognitive disabilities or with low literacy. Here are some principles that can be applied for structuring web contents (National Center on Disabilities and Access to Education, 2007):

• Headings for organizing content that will make a content easy to read and navigate
• Simple language and Active voice usage for making sure students with cognitive disabilities understand
• Slang and Jargon avoidance for making sure students with cognitive disabilities are not confused.
• Empty (white) space for improving readability
• Illustration as text supplementary
• Spelling and grammar checking

I thing that is enough for web site layout exploration, I will continue my text-formatting exploration in the next time.
