Patterns of Verbal Mediation During Problem Solving: A Sequential Analysis of Self-Explanation

The explanations that participants give themselves (self-explanations) while learning or solving problems have been shown to be positively associated with various performance measures. The major aim of this study was to identify patterns of self-explanation that distinguish between good and poor problem solvers. Thirty-two Grade 9 students were asked to solve 3 mixture problems—1 warm-up problem and 2 test problems—while thinking aloud. The problem-solving process was videotaped, protocols were transcribed, and 5 content categories were identified. Through a sequential analysis, patterns of self-explanation that differentiate between good and poor problem solvers were identified.
