Measuring the Nature of Performance Differences: A Process Approach.
Rowe, Helga A. H.
An exploratory study was undertaken to provide a means of quantifying some of the components of the problem solving process. The focus was on actual problem solving behaviors and strategies as they occurred in relation to different cognitive tasks and subject characteristics. Cognitive tasks included items from Wechsler and Binet intelligence tests, simple mathematical tasks, and verbal and performance tasks. The data for the study were provided by tape recordings of the 'thinking aloud' protocols of the individual attempts of 89 adults to solve 12 tasks each. All protocols were transcribed verbatim, timed in units of 3-second intervals, and categorized according to the taxonomy of 18 strategy variables. The unit of analysis was the 3-second interval, classified according to strategy content. The problem solving behavior documented in this manner on the 12 tasks per subject yielded a total of 41,960 responses, time sequence of responses having been kept intact for each subject and task. Initial results indicate that quantifiable features of the problem solving process may provide a means for the description of performance differences between subjects of varying levels of measured intelligence, competence and speed of problem solving.
