The study compared the effectiveness of two commonly used questioning sequences with four preschool developmentally delayed male children, aged 3 to 5 years, and their four adult trainers. The Full Model to Open Question sequence began with presenting the child with a model of the correct answer and then proceeded to increasingly less restricted choices until the open ended request ("Tell me about this"). The Open Question to Full Model sequence begins with the open question and proceeds through the sequence in reverse order until the child responds correctly. Each S received each training sequence for two sets of responses. Results indicated that the Full Model to Open Question strategy required fewer training sessions than the Open Question to Full Model strategy with all four Ss and trainers. Although both strategies were successful in teaching the target responses, under the Full Model to Open Question condition, each S appeared to evidence a "learning to learn" phenomenon with fewer sessions necessary for the second set of responses taught.
