Description

The article recommends determining the most efficient intervention design by shortening instruction while extending the outcome measure. "These findings support the use of a shorter intervention (i.e., 11 vs. 16 sessions) coupled with the revised dependent measure." In this study the intervention was reduced from 16 to 11 sessions (8.25 vs. 13.3 hours) while the pre-/posttest prompts were expanded from 25 to 30 errors, and students still improved on more error types than in the prior 16-session study.

Design Implications

Context

Requirements

• Dependent measure with enough error instances to avoid a ceiling effect and expand the measurable range of performance
• Explicit strategy instruction with mastery criterion maintained despite fewer sessions

Constraints

• The shortened intervention still required 8.25 hours and 11 sessions; the authors call for further investigation of even shorter intervention times

Target Learners

• postsecondary students with intellectual and developmental disabilities

Learning Goals

• editing skills in written expression

Claims

• Edit Strategy Improves Total Editing Errors Posttest [+M]
• Edit Strategy Error Type Posttest Pattern [+M]
