The Spiral of Development in Robbie Case's Staircase Model
A major insight of Robbie's theoretical work is that forms in cognitive development recur in cycles.
For instance, 3- or 4-year-olds (i.e., substage 3 of the Interrelational stage) show a functional-structural relation to children in the preceding sensorimotor substages analogous to that of 15- or 16-year-olds vis-a-vis children in the mental-processing (or school age) substages of the Dimensional (Concrete Operational) stage. Other functional-structural similarities of this sort are found in Robbie's model which, along with my levels of M-capacity growth and learning mechanisms, both of which he accepted, explicate the "spiral of development" idea in ways that may open new possibilities. This is a controversial but important issue for development and education.
