What happens during instruction: is any metaphor necessary?

This article provides a response to Stone's review and analysis of the scaffolding metaphor as it is applied to research applications for students with learning disabilities. We propose that, to advance the field of instructional research with students with learning disabilities, all available literature should be used when interpreting findings for instructional procedures for students with learning disabilities. Only when all of the intervention research literature in learning disabilities is examined can reliable conclusions be drawn regarding the efficacy of instructional procedures.
