The impact of the coronavirus disease 2019 pandemic on physical activity in U.S. children

BackgroundDaily moderate-to-vigorous physical activity (MVPA) is vital to the physical, mental, and social well-being of children. Early restrictions during the coronavirus disease 2019 (COVID-19) pandemic included the closure of schools and physical activity (PA) amenities across the US. This study aimed to examine the impact of the pandemic on the PA and play behavior of U.S. children and to provide evidence-based recommendations to improve their PA.MethodsA cross-sectional, online, parent-reported survey was conducted of children aged 3–18 years between April and June 2020 to assess light PA and MVPA using a modified Godin Leisure-Time Exercise Questionnaire. Additional items included family/child socioeconomic demographics, child adaptability to the pandemic, and community access. The survey was shared through social media and snowball sampling distribution.ResultsAnalysis of 1310 surveys indicated child PA scores declined significantly during the pandemic (from 56.6 to 44.6, max 119, p < 0.001). Specifically, MVPA score decreased (from 46.7 to 34.7, max 98, p < 0.001) while light PA remained the same. Age-based changes were seen in the quantity, variety, and intensity of PA, with the lowest pandemic-related impact seen in preschoolers and the highest in high schoolers (–4.7 vs. –17.2, p < 0.001). Community-based peer PA decreased across all age groups.ConclusionThis study shows decreased PA levels in U.S. children, according to parent reporting, during the COVID-19 pandemic. Recommendations for community leaders, educators, and parents to improve PA in children are provided. With continued spread of COVID-19, these results and recommendations may be imperative to the physical well-being of U.S. children.

South African Teachers’ Attitudes toward the Inclusion of Learners with Different Abilities in Mainstream Classrooms

This research sought to examine South African teachers’ attitudes toward the inclusion of learners with different abilities in their hypothetical mainstream classrooms. Participants were 93 South African teachers who responded to the Teachers’ Attitudes and Expectations Scale, a measure developed for this study, regarding four vignettes depicting learners with different types of impairments. Overall, teachers reported that inclusion would benefit learners’ social development (mean scores from 2.57 to 3.35) more than their intellectual development (mean scores from 2.14 to 2.83). It also was found that teachers overwhelmingly were more confident about including learners with Down syndrome into their hypothetical mainstream classes when compared with the inclusion of learners with other disabilities, F(3, 90) = 9.59, p < 0.01. The results suggest that providing teachers with sufficient resources within the classroom and training that includes hands-on experience with children with disabilities could positively influence their attitudes toward the inclusion of learners with disabilities in their classrooms.     

A comparison of the menstruation and education experiences of girls in Tanzania,Ghana, Cambodia and Ethiopia

The barriers to menstrual hygiene management faced by adolescent schoolgirls in low-income countries are gaining interest at practice and policy levels. The challenges include inadequate water, sanitation and disposal facilities for the management of menses with privacy and dignity, and insufficient guidance to help girls feel confident in attending school during menses. The studies described here aimed to examine how menarche impacts the lives of schoolgirls in three low-income countries (Ghana, Cambodia and Ethiopia). The focus included girls’ school participation; their relationship with parents, teachers and peers; their evolving sanitation and hygiene needs; their understanding of cultural issues and taboos around menses; and what education, if any, they received prior to and during puberty. This comparative analysis was aimed at identifying similarities between the three countries that would enable the adaptation to each context of a training book on menstruation issues for girls, which was developed from a previous study conducted in Tanzania. In all three countries, participatory activities were utilised with girls and results were analysed using grounded theory. Findings included: similarities regarding the importance of culture in perpetuating negative attitudes towards menstruation, limited provision of health information and insufficient facilities within schools. Differences were revealed regarding menstrual myths, parent–child dynamics, sources of guidance and student–teacher relations. There is a critical knowledge gap around menstruation and girls’ education in these contexts that must be addressed to ensure that girls experience a positive menarche and can manage menstrual hygiene.     

Communicating with medical library users during COVID-19

Background:The Harvey Cushing/John Hay Whitney Medical Library serves a community of over 22,000 individuals primarily from the Yale Schools of Medicine, Public Health, and Nursing and the Yale New Haven Hospital. Though they are geographically close to one another, reaching these disparate populations can be a challenge. Having a clear and thorough communication plan has proved invaluable in transcending communication chasms, especially in recent times of crisis.Case Presentation:This article describes the Harvey Cushing/John Hay Whitney Medical Library''s methods for communicating and promoting its remote resources and services in response to coronavirus disease 2019 (COVID-19). It details our communication strategies and messages leading up to, and after, the Yale campus was closed and specifies how we pivoted from reaching users inside the library to reaching our audiences remotely.Conclusions:Our communication plan has provided the foundation for all of our messaging, be it print or digital media. In recent moments of crisis, it has been especially helpful for planning and executing large scale messaging. Similarly, knowing whom to contact around our organization to promote our message in different and broader ways has been extremely beneficial.     

Providing written feedback on students’ mathematical arguments: proof validations of prospective secondary mathematics teachers

Mathematics teachers play a unique role as experts who provide opportunities for students to engage in the practices of the mathematics community. Proof is a tool essential to the practice of mathematics, and therefore, if teachers are to provide adequate opportunities for students to engage with this tool, they must be able to validate student arguments and provide feedback to students based on those validations. Prior research has demonstrated several weaknesses teachers have with respect to proof validation, but little research has investigated instructional sequences aimed to improve this skill. In this article, we present the results from the implementation of such an instructional sequence. A sample of 34 prospective secondary mathematics teachers (PSMTs) validated twelve mathematical arguments written by high school students. They provided a numeric score as well as a short paragraph of written feedback, indicating the strengths and weaknesses of each argument. The results provide insight into the errors to which PSMTs attend when validating mathematical arguments. In particular, PSMTs’ written feedback indicated that they were aware of the limitations of inductive argumentation. However, PSMTs had a superficial understanding of the “proof by contradiction” mode of argumentation, and their attendance to particular errors seemed to be mediated by the mode of argument representation (e.g., symbolic, verbal). We discuss implications of these findings for mathematics teacher education.     

Extending the understanding of mobile banking adoption: When UTAUT meets TTF and ITM

Mobile banking (mBanking) enables customers to carry out their banking tasks via mobile devices. We advance the extant body of knowledge about mBanking adoption by proposing a model for understanding the importance and relationship between the user perception of mBanking, initial trust in mBanking services, and the fit between the technology and mBanking task characteristics. We synergistically combine the strengths of three IS theories – task technology fit (TTF) model, unified theory of acceptance and usage of technology (UTAUT), and initial trust model (ITM). The model was tested in a study conducted in Portugal, one of the European Union (EU) countries with the highest mobile phone adoption. Based on the sample of 194 individuals we applied partial least squares (PLS) to test the conceptual model propose. The path significance levels were estimated using the bootstrapping method (500 resamples). The study found that facilitating conditions and behavioral intentions directly influence mBanking adoption. Initial trust, performance expectancy, technology characteristics, and task technology fit have total effect on behavioral intention. The paper offers valuable insights to decision-makers involved in the implementation and deployment of mBanking services. For researchers, the paper highlights the usefulness of integrating TTF, UTAUT and ITM in the development of a decision support framework to study the adoption of new technologies.
