Learning in critter corral: evaluating three kinds of feedback in a preschool math app

We describe a freely available iPad app for preschoolers aimed at helping children develop robust early number concepts for the numbers 1-10. We will present results of an in-progress study, involving pre-post learning measures, in-game learning measures, and video data, aimed at evaluating the effectiveness of the app and of comparing three models of feedback. We created three versions of the app, each of which employs a different kind of feedback when the learner solves a problem incorrectly. In the Implication Feedback condition (IF), the learner sees that their incorrect answer resulted in too many or too few, and they add more or take some away to fix it. In the Corrective Feedback condition (CF) the learner is shown the correct answer after a mistake and why it is correct, and they imitate the correct answer. In the Answer until Correct condition (AUC), learners are given an indication that they have made a mistake, and they continue trying until they answer correctly.
