Problem-Solving Strategies in Learning Disabled and Normal Boys: Developmental and Instructional Effects

A developmentally sensitive problem-solving task, the 20-Questions Game, was utilized in this study to examine development- and treatment-related variables among 48 learning disabled and 48 normal boys of two age levels (8-10 years old and 11-13 years old). Subjects performed on three different versions of the experimental task before, immediately after, and two weeks after receiving one of two treatment packages, which differed in their emphasis on task-specific and metacognitive strategies. Results indicated that both younger boys and learning disabled boys demonstrated less efficient problem-solving skills than their older and normally achieving peers. In all subject groups, boys' ability to make use of specific problem-solving skills was highly influenced by variations in stimulus characteristics. Brief training was effective in improving the performance of all subject groups on trained and untrained materials at posttest and follow-up trials. However, expected differences in effectiveness between treatment packages were not realized.
