This article focuses on curriculum analysis, an aspect of direct instruction that is frequently neglected or obscured by an emphasis on classroom management and teacher performance. Explicit strategies that are used to teach higher cognitive skills and the importance of teacher training in the appropriate use of direct instruction are discussed.…

Conclusion about site-specific determinants of educational outcomes of the controversial longitudinal evaluation of the Follow Through programs (1976) are challenged again by reexamining the Direct Instruction model data. Reanalysis confirms earlier critiques and supports more recent research funding on the relationship between types of…

This article presents research-based examples of effective instructional approaches for improving the quality of stories and essays written by students with learning disabilities. A common goal of the studies examined was to teach students how to organize writing tasks, generate ideas about the writing topics, and produce final written products…
