From the text: In the first iteration of teachingresearch on problemsolving, Baker employed a traditional lecture format but with a strong focus on problemsolving. Thus, problems were posed in a stepbystep fashion with frequent repetition, sequencing similarly structured problems as a means of concept scaffolding. Thus, the lesson format would have been much the same as represented by Dias, and the intent as in both Czarnocha and Dias was to transition students as rapidly as possible from a spontaneousarithmetical understanding i.e. their intuitive reasoning with whole numbers to a structuralalgebraic one.
