Many of my students have really liked L.E. Berk and A. Winsler's (1995):
Scaffolding Children's Learning: Vygotsky and Early Childhood Education.
Washington, D.C.: National Association for the Education of Young Children.
It's more than an article, but it's very well written and helpful, I think.
I'll be interested in the other recommendations people will make.
