Data collection involves assigning a 1-4, poor-to-good rating to children’s responses. For example, Beecher said, if a teacher asks a child to choose a song by touching the TAP-It screen, the child gets a rating of 4 for touching the screen and making eye contact with the teacher. If he needs prompting, perhaps with a touch on his arm, he’ll get a 3. If the teacher needs to guide his hand to the screen, the rating is 2. A 1 means no response.
A starting point for research
TAP-It is short for Touch Accessible Platform for Interactive Technology. It isn’t the first interactive device designed for children with developmental and physical problems, but it’s unusually tough. Kids can pound on it. Its touch sensitivity level can be changed so that a random tap doesn’t register as a decisive movement.
