Bio Note: Larry L. Hatfield recently retired after 56 years in higher education (Universities of Georgia and Wyoming). In the early 1970s he began his neo-Piagetian journey to “becoming a constructivist teacher-researcher.” His deepest influences were learning from his colleagues, Les Steffe and Ernst von Glasersfeld, at UGA and beyond, as they built their analyses and elaborations of RC.
