Here is a very helpful resource that I’ve put on the Content & Curriculum page.
SENSwitcher (online resource) is a suite of 132 activities designed to help teach computer skills to people with profound and multiple learning difficulties, especially those who need to develop skills with alternative input devices. These activities target skills sequentially, from purely experiential through cause and effect, switch building, timed activation, targeting and row scanning.
The activities have been developed by InclusiveTechnology and implementation strategies have been prepared by the folks at Priory Woods. This systematic set of activities have been designed to be used online or downloaded to be used offline. We have experienced difficulties in installing the programs after downloading them, but they work fine online. SENSwitcher, along with support material, can be found at Northern Grid.
SENSwitcher runs in both Windows and Mac.
