High school intervention for influenza biology and epidemics/pandemics: impact on conceptual understanding among adolescents

Accuracy of COVID-19 relevant knowledge among youth: Number of information sources matters

Can comics effectively convey scientific knowledge about COVID-19 to youth? What types and how many sources of information did youth have about COVID-19 during the pandemic? How are sources of information associated with accurate COVID-19 knowledge? To answer these questions, we surveyed youth in grades 5-9 in a Midwestern United States school district in the winter of 2020-2021. The online survey used measures of COVID-19 knowledge and sources, with an embedded experiment on COVID-19 relevant comics. Guided by an integrated science capital and just-in-time health and science information acquisition model, we also measured level of science capital, science identity, and utility of science for health and society. The school district protocol required parental consent for participation; 264 of ~15,000 youth participated. Youth were randomly assigned one of four comic conditions before receiving an online survey. Results indicate that, similar to knowledge gains in comic studies on other science topics, reading the comics was associated with 7 to 29% higher accuracy about COVID-19. We found that youth reported getting information about COVID-19 from between 0-6 sources including media, family, friends, school, and experts. The bivariate positive association of news versus other sources with accuracy of knowledge did not persist in the full model, yet the positive association of a higher number of sources and accuracy did persist in the multivariate models. The degree of valuing the utility of science for their health moderated the number of sources to accuracy association. Those with less value on science for health had a stronger positive association of number of sources and accuracy in COVID-19 knowledge. We conclude that during a pandemic, even with health and science information ubiquitous in the news media, increasing youth access to a variety of accurate sources of information about science and health can increase youth knowledge.

What College Biology Students Know about How Vaccines Work

Vaccines are an important and societally relevant biology topic, but it is unclear how much college biology students know about how vaccines work and what inaccurate ideas they have about that process. Therefore, we asked more than 600 college students taking biology courses at various levels to explain, "How does a vaccine work?" in a free-response format. Based on authoritative sources and responses from immunology and other biology faculty, we created a rubric to gauge the basic knowledge and accuracy present in student responses. Basic knowledge was defined as knowing that vaccines mimic the pathogen, elicit an active immune response, and provide protection against future infection. Accuracy was defined as the absence of scientifically inaccurate ideas. We found that advanced biology majors score significantly higher in basic knowledge and accuracy when compared with all other student groups, but there were no differences between entering biology majors, pre-health majors, and non-pre-health majors. We also uncovered a variety of inaccurate ideas, with the most common being that vaccines contain the original, unmodified pathogen. These results provide a new way to gauge college student understanding of how a vaccine works and enrich our understanding of what college students know about this process.

Teaching and learning about respiratory infectious diseases: A scoping review of interventions in K-12 education

The pandemic outbreak of COVID-19 has highlighted an urgent need for infectious disease education for K-12 students. To gather a better understanding of what educational interventions have been conducted and to what effect, we performed a scoping review. We identified and examined 23 empirical researcher- and teacher-designed studies conducted in the last 20 years that have reported on efforts to help K-12 students learn about infectious diseases, with a focus on respiratory transmission. Our review shows studies of educational interventions on this topic are rare, especially with regard to the more population-scale (vs. cellular level) concepts of epidemiology. Furthermore, efforts to educate youth about infectious disease primarily focused on secondary school students, with an emphasis on interactive learning environments to model or simulate both cellular-level and population-level attributes of infectious disease. Studies were only mildly successful in raising science interest, with somewhat stronger findings on helping students engage in scientific inquiry on the biology of infectious diseases and/or community spread. Most importantly, efforts left out critical dimensions of transmission dynamics key to understanding implications for public health. Based on our review, we articulate implications for further research and development in this important domain.

Tipping the Fencesitters—The Impact of a Minimal Intervention Enhanced with Biological Facts on Swiss Student Teachers’ Perception of HPV Vaccination Safety

Not much is known about the role of scientific knowledge in vaccination decision making. This study is based on previous findings that the concern about the human papillomavirus (HPV) agent mutating back to a virulent HPV was common among Swiss student teachers and turned out to be one factor of vaccine hesitancy. The study investigate the impact of a standard public health brochure describing the effectiveness, safety, and importance of HPV vaccination on young student teachers, and the additional effect of supplementing the standard brochure with biological arguments against the mutation concerns. It uses a pre-posttest design and assigns participants randomly to two groups, one reviewing a standard public health brochure, the other the same brochure enhanced with additional biological information. Participants in both groups showed a significant positive change in their beliefs about vaccination safety, effectiveness, and importance in preventing cervical cancer. Post hoc analysis showed significant safety beliefs gain for the subgroup of participants who received the biology-enhanced text and held moderate, rather than high or low, pretest safety beliefs—the so-called fencesitters. We conclude that these fencesitters may particularly profit from even minimal (biologically supplemented) interventions, an effect that should receive more attention in future research.

Connecting the Dots from Professional Development to Student Learning

Following professional development (PD), implementation of contemporary topics into high school biology requires teachers to make critical decisions regarding integration of novel content into existing course scope and sequence. Often exciting topics, such as neuroscience, do not perfectly align with standards. Despite commitment to enacting what was learned in the PD, teachers must adapt novel content to their perceptions of good teaching, local context, prior knowledge of their students, and state and district expectations. How teachers decide to integrate curricula encountered from PD programs may affect student outcomes. This mixed-methods study examined the relationship between curricular application strategies following an inquiry-based neuroscience PD and student learning. Post-PD curricular implementation was measured qualitatively through analysis of teacher action plans and classroom observations and quantitatively using hierarchical linear modeling to determine the impact of implementation on student performance. Participation in neuroscience PD predicted improved student learning compared with control teachers. Of the two distinct curricular implementation strategies, enacting a full unit produced significantly greater student learning than integrating neuroscience activities into existing biology units. Insights from this analysis should inform teacher implementation of new curricula after PD on other contemporary biology topics.

Assessing adolescents' critical health literacy: How is trust in government leadership associated with knowledge of COVID-19?

This study explored relations between COVID-19 news source, trust in COVID-19 information source, and COVID-19 health literacy in 194 STEM-oriented adolescents and young adults from the US and the UK. Analyses suggest that adolescents use both traditional news (e.g., TV or newspapers) and social media news to acquire information about COVID-19 and have average levels of COVID-19 health literacy. Hierarchical linear regression analyses suggest that the association between traditional news media and COVID-19 health literacy depends on participants’ level of trust in their government leader. For youth in both the US and the UK who used traditional media for information about COVID-19 and who have higher trust in their respective government leader (i.e., former US President Donald Trump and UK Prime Minister Boris Johnson) had lower COVID-19 health literacy. Results highlight how youth are learning about the pandemic and the importance of not only considering their information source, but also their levels of trust in their government leaders.

"The evil virus cell": Students' knowledge and beliefs about viruses

Education about virus biology at school is of pivotal interest to raise public awareness concerning means of disease transmission and, thus, methods to prevent infection, and to reduce unnecessary antibiotic treatment due to patient pressure on physicians in case of viral diseases such as influenza. This study aimed at making visible the knowledge of Austrian high school and university students with respect to virus biology, virus structure and health-education issues. The data presented here stem from comprehensive questionnaire analyses, including the task to draw a virus, from a cross-sectional study with 133 grade 7 and 199 grade 10 high school students, and 133 first-year biology and 181 first-year non-biology university students. Analyses were performed both quantitatively and qualitatively. ANOVA revealed a highly significant group effect for total knowledge relating to virus biology and health issues (F(3, 642) = 44.17, p < 0.01, η²p = 0.17). Specific post-hoc tests by means of the Tukey test showed significant differences between all groups (p < .01) with the exception of 1^st year non-biology students and grade 10 high school students. Students enrolled in university-level biology outperformed all other groups, even though they had not yet encountered this topic at their courses; part of this phenomenon might be due to their affinity for learning about biological topics. However, even many first-year biology students had a high number of severe misconceptions, e.g., defining a virus as a pro- or eukaryotic cell, or falsely naming malaria as a viral disease. Since there was no significant difference in virus-related knowledge between high schools, virus biology seems to have been taught similarly among the tested schools. However, the majority of participants stated that the virus-related knowledge they had acquired at school was not sufficient. Based on the results presented here we urgently suggest improving and intensifying teaching this topic at school, since virus-related knowledge was by far too fragmentary among many participants. Such lack of health-relevant knowledge may contribute to pressure on physicians by patients to unnecessarily prescribe antibiotics, and possibly lead to potentially dangerous neglect concerning vaccination. The effectiveness of newly developed virus-related teaching units and material could be tested with the instrument used here.

The effectiveness of disaster risk communication: a systematic review of intervention studies

INTRODUCTION

A disaster is a serious disruption to the functioning of a community that exceeds its capacity to cope within its own resources. Risk communication in disasters aims to prevent and mitigate harm from disasters, prepare the population before a disaster, disseminate information during disasters and aid subsequent recovery. The aim of this systematic review is to identify, appraise and synthesise the findings of studies of the effects of risk communication interventions during four stages of the disaster cycle.

METHODS

We searched the Cochrane Central Register of Controlled Trials, Embase, MEDLINE, PsycInfo, Sociological Abstracts, Web of Science and grey literature sources for randomised trials, cluster randomised trials, controlled and uncontrolled before and after studies, interrupted time series studies and qualitative studies of any method of disaster risk communication to at-risk populations. Outcome criteria were disaster-related knowledge and behaviour, and health outcomes.

RESULTS

Searches yielded 5,224 unique articles, of which 100 were judged to be potentially relevant. Twenty-five studies met the inclusion criteria, and two additional studies were identified from other searching. The studies evaluated interventions in all four stages of the disaster cycle, included a variety of man-made, natural and infectious disease disasters, and were conducted in many disparate settings. Only one randomised trial and one cluster randomised trial were identified, with less robust designs used in the other studies. Several studies reported improvements in disaster-related knowledge and behaviour.

DISCUSSION

We identified and appraised intervention studies of disaster risk communication and present an overview of the contemporary literature. Most studies used non-randomised designs that make interpretation challenging. We do not make specific recommendations for practice but highlight the need for high-quality randomised trials and appropriately-analysed cluster randomised trials in the field of disaster risk communication where these can be conducted within an appropriate research ethics framework.
