Abstract
The mathematical thinking skills project (Tanner & Jones, 1995)
reported that classes which followed a course emphasising metacognitive
skills were not only more successful than controls in assessments of those
skills, but also in assessments of mathematical development. Ethnographic
data revealed significant variations in the teaching style from teacher to
teacher and was used to classify the teachers into four groups. This paper
discusses the teaching styles of the two most successful groups: the "dynamic
scaffolders" and the "reflective scaffolders".
