Refutations in science texts lead to hypercorrection of misconceptions held with high confidence

Abstract

Misconceptions about science are often not corrected during study when they are held with high confidence. However, when corrective feedback co-activates a misconception together with the correct conception, this feedback may surprise the learner and draw attention, especially when the misconceptions are held with high confidence. Therefore, high-confidence misconceptions might be more likely to be corrected than low-confidence misconceptions. The present study investigates whether this hypercorrection effect occurs when students read science texts. Effects of two text formats were compared: Standard texts that presented factual information, and refutation texts that explicitly addressed misconceptions and refuted them before presenting factual information. Eighth grade adolescents (N = 114) took a pre-reading test that included 16 common misconceptions about science concepts, rated their confidence in correctness of their response to the pre-reading questions, read 16 texts about the science concepts, and finally took a post-test which included both true/false and open-ended test questions. Analyses of post-test responses show that reading refutation texts causes hypercorrection: Learners more often corrected high-confidence misconceptions after reading refutation texts than after reading standard texts, whereas low-confidence misconceptions did not benefit from reading refutation texts. These outcomes suggest that people are more surprised when they find out a confidently held misconception is incorrect, which may encourage them to pay more attention to the feedback and the refutation. Moreover, correction of high-confidence misconceptions was more apparent on the true/false test responses than on the open-ended test, suggesting that additional interventions may be needed to improve learners' accommodation of the correct information.
