The Power of Nudging: Exploring Three Interventions for Metacognitive Skills Instruction across Intelligent Tutoring Systems

Understand

Deductive domains are typical of many cognitive skills in that no single problem-solving strategy is always optimal for solving all problems.

• It was shown that students who know how and when to use each strategy (StrTime) outperformed those who know neither and stick to the default strategy (Default).
• In this work, students were trained on a logic tutor that supports a default forward-chaining and a backward-chaining (BC) strategy, then a probability tutor that only supports BC.
• We investigated three types of interventions on teaching the Default students how and when to use which strategy on the logic tutor: Example, Nudge and Presented.
