There was a time when students with special needs faced a choice (made for them by their school!) of either using a standard computer, and struggling, or spending large amounts on specific special needs software. These days, accessibility has been built into so many areas of standard software (eg all of the accessibility in Windows 7) that much, much better support is provided for students with special needs.
One of the unsung heroes of helping students with special needs is OneNote (part of Office 2010) which allows you to use so many different types of media, it readily provides ways for students to take notes, collate information, and store information, in audio, video, image and conventional note format. For example, for students with dyslexia, OneNote has many features that can help students take notes faster and in different ways, stay organised, and meet literacy challenges, such as spelling and grammar.
Here are five ways that OneNote can help students with dyslexia take better notes:
You can see the full detail, and the specific notes on how to use these features, on the main Microsoft education site, along with a short video demonstration of the features.
