The effect of multimedia discrepancies on metacognitive judgments

This study investigated undergraduate students’ metacognitive judgments while learning about complex science topics using multimedia material (text and graph). A within-subjects design was used to examine the effect of discrepancies on study-time allocation, metacognitive judgments and inference generation. There were three types of discrepancies: none, text (between two ideas in the text) and text and graph (between the text and graph). Forty (N = 40) participants completed 12 trials where they were asked to provide six judgments: Ease of Learning judgments (EOLs), immediate and delayed Judgments of Learning (JOLs) for both text and graph and Retrospective Confidence Judgments (RCJs). Overall, participants provided significantly lower JOLs for content that contained discrepancies but RCJs remained high across conditions. Discrepancies did not influence study-time allocation, but did significantly influence inference scores. Overall, results suggest that participants’ judgments are different for different aspects of multimedia content and may be based on the text.

► Discrepancies influenced metacognitive judgments and responses but not study time.
► Material that contained discrepancies was judged as less understood by participants.
► Confidence in responses remained high regardless of judgments of understanding.
► Accuracy of judgments is different depending on when made and type of content.
► Participants may detect discrepancies but lack prior knowledge or strategies.
