Some of the online explainer videos for physics present misconceptions as scientifically correct explanations. Even so, some of these videos achieve good ratings on online platforms. A possible reason is that explainer videos with misconceptions foster an "illusion of understanding"-the mistaken belief that a topic has been understood. Misconceptions close to everyday experiences might appear more attractive than scientifically correct explanations. This experimental study ( = 149 physics learners with a low prior knowledge on average, sample of convenience) was conducted to explore this effect. Two explainer videos were developed to be comparable in terms of comprehensibility and duration. The explanatory approach was the only difference between the two videos. While the experimental group watched a video introducing the concept of force using misconceptions, the control group watched a scientifically correct video. Learners from the experimental group developed an equal belief of understanding, but more misconceptions and fewer scientifically correct conceptions than those from the control group. We argue that this illusion of understanding might become problematic (a) in physics instruction because students who have watched a misleading video might regard further teaching in school as irrelevant, and (b) learners might tend to rate videos including misconceptions better on an online platform like YouTube. Future studies should examine these two possible consequences.

Developing generic clinical trial animated explainer videos in the UK: results of a survey and case study.
Trials
January 2025
Oxford Clinical Trials Research Unit, University of Oxford, Oxford, UK.
Background: Animated short videos used to explain a concept or project are often called animated explainer videos (AEVs). AEVs can supplement or provide an alternative to participant information sheets as a means of giving information about clinical research to potential participants. Current use of AEVs tends to focus on the specifics of a particular trial, yet there are many common aspects of clinical research regardless of the interventions being investigated that can be poorly covered in current trial materials.

School of Medicine, University of Nottingham, Nottingham, United Kingdom.
The COVID-19-Curated and Open Analysis and Research Platform (CO-CONNECT) project worked with 22 organizations across the United Kingdom to build a federated platform, enabling researchers to instantaneously and dynamically query federated datasets to find relevant data for their study. Finding relevant data takes time and effort, reducing the efficiency of research. Although data controllers could understand the value of such a system, there were significant challenges and delays in setting up the platform in response to COVID-19.

Article Synopsis
- The COVID-19 pandemic led to the quick creation of scarce resource allocation policies (SRAPs) to manage the increased demand for health services amid limited capacity.
- A randomized clinical trial examined whether a 6-minute educational video about the University of California Health's SRAP could enhance participants' understanding and trust in health systems to ethically apply these policies during the pandemic.
- The study involved 1971 adult participants, focusing on their knowledge and anxiety levels regarding SRAPs, with the results indicating significant effects on self-reported understanding and trust following the video intervention.*

Background: Social norm appeals are effective in promoting sustainable majority behavior but could backfire when the target behavior is only performed by a minority of people. However, emphasizing that an increasing number of people have started engaging in the behavior or that the majority approve the behavior might prevent such negative effects. However, only a few studies have investigated the combination of descriptive minority and injunctive majority social norm appeals, with inconsistent results.
