After looking at assistive technology in general I decided to focus on visually impaired students. I feel like all of us will have to deal with a visually impaired student during some point in our teaching careers. Recent polls show that more and more people are lacking health insurance, which usually includes some form of eye care. If students do not have access to glasses because their parents cannot afford it you will need to take steps to make sure that the student is given the best chance to learn possible. If you notice a student straining to see what is on the board, or they have their nose practically on any paper that they are reading they may have a visual problem. Most of these types of problems can be solved by just moving the student closer to the board, or getting some large print material. If the problem is serious enough you may check with your school nurse to see if there are any programs out there to get the student a free or reduced priced pair of glasses.
Next I am going to talk about students that have more serious visual impairment issues. These students will not be helped by moving closer to the board, or something that basic. They will need much greater help in being able to read and see classroom material. Many great new tools have come into the market in the last few years. There are screens that you can put a book under and it enlargens the print of the book. This can save money in the long run, as you do not need to get as many books in large print. There are also board magnifiers that can enlargen the images on the board on a computer screen that sits on the students desk. The list could go on and on with all the new technology out there. The most important thing to remember is that you should talk to your students and their family ahead of time, and to have everything in place for the student beforehand. This can help to save on any embarrassment that the student may feel. In my resources I will link the website that I looked at that has a lot of useful assistive technology for the visually impaired.
