Computer assisted instruction (CAI) has had mixed results in its effectiveness in treating children with receptive language disorders. Current literature lacks sufficient information on the effect of CAI on wh-question comprehension in children with receptive language disorders. The Purpose of this investigation was to examine the effect of CAI using the iPad application QuestionIt© in children with receptive language disorder. Three participants, ranging from 7 to 10 years of age diagnosed with receptive language disorders, were recruited for this investigation. The participants received 20-25-minute biweekly sessions over 2 to 5 weeks with each participant receiving at least four intervention sessions. A single-case A-B research design was used for this investigation. Each participant interacted with the QuestionIt© application for an average of 11 minutes at the beginning of each intervention session. Participant 1 and Participant 3 met criteria in response to wh-questions who, what, what doing, where, and when within the first four sessions and Participant 2 met criteria after 10 sessions. All three participants’ data points fell outside the upper two-standard deviation band limit indicating a significant effect on wh-question comprehension. The results of this investigation suggest Questionit© to be effective on wh-comprehension for school age children with receptive language disorder. Future research is needed to investigate the effectiveness of CAI software programs in the treatment of receptive language disorders. Key words: computer-based instruction, computer assisted instruction, wh-question comprehension, receptive language disorder, QuestionIt© iPad application.
