The paper draws on the Vygotskyan view of instruction, advocating the
support of learners within their individual Zones of Proximal Developm
ent. It describes an instructional design developed iteratively - grad
ually building in ''scaffolding'' techniques to support the use of the
procedural facilitation of text evaluation during revision - and the
open-ended management of its provision to students, so that they could
''fade it out'' themselves. The study took place in a writing class f
or students at basic writing levels. The present, post hoc analysis is
concerned with individual differences among three members of the clas
s identified as weak, intermediate and more advanced novices while lea
rning to revise within that program.
