This study investigated the relative effectiveness of two methods of teaching an efficient questioning strategy to students with learning disabilities. The methods compared were (a) cognitive modeling alone in the use of constraint-seeking questions, and (b) cognitive modeling and verbalization in the use of constraint-seeking questions, involving explicit and consistent instruction and feedback. Sixty subjects with learning disabilities were assigned randomly to one of these two conditions (n = 30 in each group). A pretreatment and posttreatment design was employed, with the criterion variable being number of questions required to obtain the correct answers to two 20 questions games. Results indicated that both groups showed significant reductions from pretreatment to posttreatment in the number of questions required. The two methods of instruction did not differ significantly in effectiveness.
