dc.description.abstractActions relevant to conceptual ideas can promote thinking and learning, whether internally generated when spontaneously produced by learners (i.e., gestures), or externally generated when prompted to perform directed actions. Few studies have explored how prompting students to predict their future actions influences their thinking. This study compared the effects of internally generated predicted actions versus externally generated directed actions on undergraduate students’ (N = 67) geometry proof performance. We investigated the role of gestural replays as physical re-enactments of one’s prior actions involved in mathematical transformations. Gestural replays provide evidence of mental simulation processes of past actions. Quantitative models revealed significant benefits of gestural replays that depict students’ prior mathematical transformations on proof performance, which extended to both externally generated directed actions and internally generated predicted actions. Qualitative analysis further illustrates ways gestural replays support embodied simulations that can bridge concrete actions and generalizations needed for mathematically valid proofs.en
