Improving learning disabled students' skills at composing essays: self-instructional strategy training.

This study was conducted to determine if self-instructional strategy training would improve learning disabled students' writing. Students were taught a strategy designed to facilitate the generation, framing, and planning of argumentative essays. Training effects were investigated using a multiple-baseline across-subjects design, with multiple probes in baseline. Strategy instruction had a positive effect on students' writing performance and self-efficacy. Effects were maintained over time and transferred to a new setting and teacher. Evidence for generalization to a second genre, story writing, was also obtained. The students and their special education teacher recommended the use of the strategy with other students.
