In response to a previous article, the paper argues that effective instruction of the learning disabled is most likely to develop from systematic theoretically based research though instructional studies can contribute to theory development. Research in many other areas is necessary to develop the powerful teaching methods required. (DB)

This commentary on C. Addison Stone's paper on the scaffolding metaphor for the learning disabilities field urges that all available literature, rather than a particular metaphor, should be used to evaluate the efficacy of instructional procedures in interpreting findings of instructional research.

This commentary on C. Addison's Stone's paper on the scaffolding metaphor for the learning disabilities field suggests: (1) repositioning the metaphor in its theoretical frame; (2) considering the ways in which contexts and activities, as well as individuals, scaffold learning; and (3) examining the relationship between scaffolding and effective…

This article applies results of a previous meta-analysis of effective instructional practices with adolescents who have learning disabilities focusing on the factor, "Organization/Explicit," which contributed significant variance to effect size. This factor included the important instructional components of advance organization and explicit…

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…

This commentary on C. Addison Stone's paper on scaffolding for the learning disabilities field suggests that many current applications prevent rather than encourage transfer of responsibility to students for learning and task accomplishment and that current practices in many schools may result in "reverse-scaffolding".
