Provide options for physical action

A textbook or workbook in a print format provides limited means of navigation or physical interaction (e.g., turning pages, handwriting in spaces provided). Many interactive pieces of educational software similarly provide only limited means of navigation or interaction (e.g., using a joystick or keyboard).  Navigation and interaction in those limited ways will raise barriers for some learners – those with physical disabilities, blindness, dysgraphia, or who need various kinds of executive functioning supports. It is important to provide materials with which all learners can interact.  Properly designed curricular materials provide a seamless interface with common assistive technologies through which individuals with movement impairments can navigate and express what they know – to allow navigation or interaction with a single switch, through voice activated switches, expanded keyboards and others.
