For Sarah McLaren, who lives in a suburb of Minneapolis, talking about the spring is painful. Her daughter, a rising fourth-grader, struggles with auditory processing and receives special education services. But McLaren says her daughter had trouble keeping up with teachers on an iPad because the instruction was almost all talk.
"They'd tell her, 'Look at this problem, look at that problem. No, show me your worksheet,' " McLaren remembers. "The teachers were doing the best they could, but all those rapid verbal directions just overwhelmed her."
