Switches

For the section on Switches, in class we were presented with a video on switches and the differences between simple and specialty switches.  We viewed the use of switches and the considerations that have to be taken into account when using a switch, such as the purpose the switch is needed, what function you are trying to improve, what motor skill abilities the person has that will address the type of switch they will be able to use as well as mounting considerations.

I googled switches when I got back to my dorm to find out more information and how these are used.  There is a particular site that is great and people may want to go visit for information.  I placed this at the top of my blog page if you would like to take a look.

Also, I will attach some links for switches as well, that I found valuable and informative.  They are:

Yahoo Directory for AT sites – very useful and easy to use – removes a great deal of surfing on the web, unless of course you like that!!

In my research on the web as well as information from class, there are several very important considerations that need to be made before assigning a switch to accomplish a certain function for a student.

First of all, the educational needs of a person need to be determined.  You need to provide some ability for them to control a portion of their environment.  Switches are used for individuals with severe or multiple learning disabilities.  Consequently, in terms of classroom focus, the entire team in a school need to be involved in this process so that we can consider the MPTTT framework for the child.  The environment for the child needs to be considered in that we have to assess the factors that limit the individual as well as if there are other factors, such as a wheelchair or some type of motorized device for them to be mobile.  The switch would in this case, need to be mounted so the person could have access.  The other factor that needs to be assessed, is the person's ability to move - their muscle control.  This could vary for individuals, it could be they are able to move a knee, elbow, head or other body part.  Also, you have to consider if they have involuntary movements as this would interfere with the switch if it is installed and mounted in the wrong spot.
