The current study focused on the role of feedback on students’ prediction accuracy (calibration). This phenomenon has been widely studied, but questions remain about how best to improve it. In the current investigation, fifty-seven students from sixth grade were randomly assigned to control and experimental groups. Thirty pictures were chosen from the curriculum and these were the same in the trials for both groups, 10 for each trial. The pilot study showed all pictures had the same difficulty level and that they were appropriate for 6^th graders. During three trials, students in the experimental group received feedback about their prediction and recall. The purpose of the feedback was to assist students in monitoring their learning. Results demonstrated that students in the experimental group showed improvement in predication and prediction accuracy in trials 2 and 3. Significant differences were found among groups in trials 2 and 3, but not in trial 1. Implications and future studies are recommended.
