Refuting student teachers’ misconceptions about multimedia learning

Prior research indicates that student teachers frequently have misconceptions about multimedia learning. Our experiment with N = 96 student teachers revealed that, in contrast to standard texts, refutation texts are effective to address misconceptions about multimedia learning. However, there seems to be no added benefit of making “concessions” to student teachers’ prior beliefs (i.e., two-sided argumentation) in refutation texts. Moreover, refutation texts did not promote the selection of appropriate multimedia material. This study suggests that refutation texts addressing multimedia-learning misconceptions should be applied in teacher education. Yet, further support seems needed to aid the application of the corrected knowledge.

It’s Contagious! The Effects of Gamifying Refutation Texts on Emotions and Learning

The current study investigated the effects of gamifying refutations on emotions and learning. Refutations have a substantial body of evidence supporting their use to correct misconceptions, yet reduced efficacy has been observed for some topics that induce negative emotional reactions. We tested whether gamification could mitigate these limits given that it capitalizes on positive affective engagement. From May to December 2020, approximately 200,000 individuals were recruited from social media in Canada to engage with a non-game interactive survey as a control or a fully gamified platform focused on correcting COVID-19 misconceptions. Gamification resulted in higher levels of happiness and anxiety and lower levels of anger and skepticism in response to having misconceptions corrected by refutations. Further, participants who engaged with gamified refutations retained correct information after a brief period. Finally, positive emotions and anxiety positively predicted and negative emotions largely negatively predicted retention and support for related public health policies. Implications for scaling up and reinforcing the benefits of refutations for public engagement with science are discussed.

EXPRESS: The Effects of Experimentally Induced Emotions on Revising Common Vaccine Misconceptions

Knowledge revision is the process of updating incorrect prior knowledge in light of new, correct information. Although theoretical and empirical knowledge has advanced regarding the cognitive processes involved in revision, less is known about the role of emotions, which have shown inconsistent relations with key revision processes. The present study examined the effects of experimentally induced emotions on online and offline knowledge revision of vaccination misconceptions. Before reading refutation and non-refutation texts, 96 individuals received either a positive, negative, or no emotion induction. Findings showed that negative emotions, more than positive emotions, resulted in enhanced knowledge revision as indicated by greater ease of integrating correct information during reading and higher comprehension test scores after reading. Findings are discussed with respect to contemporary frameworks of knowledge revision and emotion in reading comprehension and implications for educational practice.

Counteracting detrimental effects of misconceptions on learning and metacomprehension accuracy: The utility of refutation texts and think sheets

Previous research has shown that misconceptions impair not only learners’ text comprehension and knowledge transfer but also the accuracy with which they predict their comprehension and transfer. In the present experiment with N = 92 university students, we investigated to what extent reading a refutation text or completing a think sheet compared with a control condition counteracts these adverse effects of misconceptions. The results revealed that both reading a refutation text and completing a think sheet supported learners with misconceptions in acquiring and accurately predicting their comprehension. Completing a think sheet additionally supported the learners in transferring their newly acquired knowledge, even though they were underconfident in their ability to do so. Moreover, learners who completed a think sheet were generally more accurate in discriminating between correctly and incorrectly answered test questions. Finally, delayed testing showed that the learning effects were quite stable, independent of the instructional method. This study reinforces the effectiveness of refutation texts and think sheets and provides important practical implications and avenues for future research.

The effects of positive and negative emotional text content on knowledge revision

Across three experiments, we sought to determine the effects of positive and negative emotional content in refutation texts on misconceptions about vaccines. The addition of negative emotional content to texts that identify, refute, and explain vaccine misconceptions improved knowledge revision observed during reading (Experiment 1). However, the addition of positive emotional content to refutation texts weakened this effect (Experiment 2). A direct comparison between negative and positive emotional content provided corroborating evidence for these findings (Experiment 3). Across experiments, results show that all refutation texts (with or without positive or negative emotional content) improved learning assessed after reading. These findings show the differential effects of emotional content on processing misconceptions about an important socio-scientific topic and provide consistent support for refutation texts as a potentially useful tool in these corrective efforts.
