When students verbalize what they know, it helps them to reflect upon and clarify the problem and focus on one step at a time. “Thinking aloud” requires talking through the details, decisions, and the reasoning behind those decisions. Struggling students, in particular, can benefit from slowing down the process, because it gives them time to fully comprehend the problem. Technology can help create problems with natural stopping points that allow students to practice this “thinking aloud” strategy—that is, to experiment, consider, and then decide their next steps.
