Learning in a digitally connected classroom: Secondary science teachers’ pedagogical reasoning and practices

Despite decades of research surrounding Information Communication Technology (ICT) use in schools, the pedagogical reasoning required to provide meaningful ICT enabled learning opportunities is rarely analysed in the literature. The purpose of this research was therefore to investigate teachers’ pedagogically reasoned practice. This study involved three exemplary Australian secondary science teachers, renowned for their expertise in utilising ICT working in classrooms where students had school issued one-to-one computers and reliable network access. The research utilised qualitative methods, including semistructured interviews, video-based observational data, and an array of lesson artefacts. The study followed a naturalistic multiple-case study design to explore the pedagogical reasoning and actions of these science teachers. The study identified different forms of pedagogical reasoning and action for a digitally connected world. Many aspects of this iterative model bear close resemblance to Shulman’s (1987) original conception of pedagogical reasoning and action. In each case, sophisticated reasoned decision-making drawing upon a range of teacher knowledge bases, most notably technological pedagogical content knowledge took place. The pedagogical reasoning and action model presented demonstrates a backward mapping approach where the use of ICT was directed at supporting the development of scientific content and educational outcomes of the mandated science curriculum. The research also found that these teachers held social constructivist beliefs for the use of ICT and intentionally designed ICT enabled opportunities from a learning affordance perspective. The research also demonstrated a reflexive relationship between the teacher’s beliefs and their pedagogical practices. Teacher activity involved significant preparatory work in the selection and curation of motivating, authoritative and multimodal Internet accessible ICT resources and tools aligned to the mandated science curriculum. In each case, the teachers had purposefully created a customised classroom online presence or website, offering students a flexible learning environment, an uncommon practice at the time of the study. The teachers designed ICT enabled learning opportunities following a guided inquiry model, frequently involving collaborative problem-based strategies. In each case, the students were the dominant users of ICT in the classroom using ICT for discovering knowledge, constructing knowledge and for sharing knowledge. The teachers’ role was predominantly one of orchestration of the learning environment, scaffolding and questioning students as they engaged with guided inquiry-based learning tasks. Ultimately the research revealed the critical role of the teacher in mediating the affordances of ICT for meaningful learning. Overall the findings offer useful insights into how exemplary science teachers’ reason and act about the use of ICT in a digitally connected classroom. An important implication for the development of initial science teacher education programs arose from the study, notably that preservice teachers require ongoing and authentic course opportunities to support the development of the technology, pedagogy, and content knowledge relevant for a digitally connected classroom

Serious games for health promotion in adolescents – A systematic scoping review

Digital gaming has broad appeal globally, with a reported 2.7 billion gamers worldwide. There is significant interest in using games to enhance learning, with ‘serious games’ being included in classrooms to engage adolescents’ learning across a range of domains. A systematic scoping review of serious games used for health promotion with adolescents was conducted to identify serious games, review the methods used to evaluate these games, and outline evidence available to support the efficacy of these games in improving knowledge, beliefs/attitudes and behaviours in the target groups. Player engagement/enjoyment was reported if assessed. A total of 21 studies were found to have met the inclusion criteria domains: ‘healthy lifestyle’ ‘sexual health’ and ‘substance use’. A heterogenous approach across studies to game design and development, duration of game play, use of a control group and measurement of outcome(s) was observed. Game efficacy was difficult to assess due to broad generalisations and lack of consistent evaluation methods. Several studies demonstrate serious games can be engaging and pedagogically effective as a learning device and behaviour-change agent. Several studies, however, had less rigorous evaluation and lacked longer-term follow up. The ability for developers to demonstrate positive short- and long-term impacts of serious games with high-quality evidence is essential to the ongoing acceptance and use of these serious games as part of the school curriculum

Rethinking adolescent school nutrition education through a food systems lens

BACKGROUND: Obesity-driven nutrition education in schools does not appear to result in healthier adolescent food choices. This study explored food systems as an alternative pedagogical approach to engage students in nutrition education. METHODS: After playing a food systems computer game, 250 13- to 16-year-old students in 5 Western Australian secondary schools, participated in group discussions to distinguish learning and interests in food systems. Discussion records were thematically coded using constant comparative analysis. RESULTS: Students reported crop growth, food production and food waste, healthier food choices, and food systems as knowledge outcomes of game play. They requested additional content on food production, costing, handling, processing, and accessing local produce. Experiential activities were preferred pedagogical approaches. CONCLUSIONS: Cross-curricular pedagogy which embraces human and planetary health through a food systems lens, can engage adolescents in nutrition education. Transformational computer games are effective to engage, educate and stimulate inquiry in food systems education

Identifying differences in nutrition-related learning interests of adolescent students

© 2021 The Authors. Journal of School Health published by Wiley Periodicals LLC. on behalf of American School Health Association. BACKGROUND: In this study, we examined nutrition-related topics among adolescent students attending schools with different Indices of Community Socio-Educational Advantage (ICSEA). METHOD: Participating students (N = 206) from 5 schools in Western Australia completed a paper-based questionnaire on nutrition-related topics. Frequencies and independent chi-square tests were used to identify differences between sexes and school ICSEA. RESULTS: Of the participating students, 75% were interested in learning about 8 of 16 topics. We found statistically significant differences by sex (p \u3c .01) for “Eating the right foods for preventing illness and disease,” “Eating the right food for being active” among girls, and “Reducing food waste” among boys. We also noted differences by school ICSEA. CONCLUSION: Acknowledging sex and socioeducational differences in teaching and learning may help teachers to engage adolescent students in nutrition education

Transformational Game Trial in Nutrition Education

The development of healthy eating habits in adolescents is challenging. Resultantly, health educators are turning to digital devices to engage young people in nutrition education. This paper focuses on the development and evaluation of a computer game (Test Game B) to support healthier food choices. Test Game B was developed at an Australian university and trialled with 72 tertiary student volunteers along with a control game (Control Game A). Both games provided information related to the progression of food along the digestive tract with knowledge of digestion, nutrition, a healthy diet and attitudes to food choice measured before and after game use. Change in these indicator variables assessed game effectiveness. The study found that the transformational aspects of problem-based learning within a digital context can support healthier food choices in young people, whilst pre-service health education teachers may require learning in food digestion to support nutrition education in schools

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

[Les attributs de recherche et d'expérience : un indicateur imparfait de la crédibilité de l'éco-étiquetage des produits agro-alimentaires]

International audienceLes auteurs postulent que les consommateurs utilisent parfois des attributs vérifiables comme un indicateur imparfait de la crédibilité d'une allégation environnementale signalant un écoproduit. Ils en déduisent que le succès d'une stratégie d'éco-étiquetage des produits agro-alimentaires ne nécessite pas simplement la réalisation d'attributs environnementaux, mais aussi la production à des niveaux adéquats d'autres attributs vérifiables corrélés, qui ensemble, signalent la crédibilité

Collaboration: Meeting the Library User's Needs in a Digital Environment

Michael Whang is the Head of Web & Internet Services, Western Michigan University Libraries, Kalamazoo, Michigan. His work involves designing and developing web interfaces, conducting usability studies and focus groups, producing screencasts and online tutorials, and investigating web metrics and emerging technologies. George Boston is an Electronic Resources Librarian at Western Michigan University, Kalamazoo, MI. Julie Hayward is a Resource Sharing Assistant at Western Michigan University, Kalamazoo, MI. Dianna Sachs is an Instructional Services Librarian at Western Michigan University, Kalamazoo, MI.Providing access to electronic resources entails several factors. After the decision to provide an electronic resource is made and the license agreement is negotiated and signed, the technical aspects of providing access must be assured. The electronic resource can be made available through the local OPAC and provisions can be made for use through other venues, such as a local web page or link resolver. It must be correctly configured to work with other resources. These may include any remote authentication protocols, local document delivery software, and other applicable resources. These and other customizations may be made through a resource’s administrative module or by correspondence with the provider. Critical to the successful access is the ongoing maintenance required to keep up to date with added features and technical enhancements within the resource. The presentation of electronic resources on a library’s website and the marketing and promotion of resources in the world of “Google” is vital in the library’s efforts to provide access to resources obtained for the user’s benefit. Usability studies, Lib-Qual?, participation in institution portals, and surveys are among the studies used to determine how to effectively reach users. The use of website “banners” to focus attention on resources and services, redesign efforts based on user studies, and flexibility in meeting and adapting to the rapidly changing technologies are guided by the Web Librarian. Making electronic resources available to library users is only worthwhile if they are able to use those resources efficiently and effectively. While traditional library instruction methods can be useful for teaching about electronic resources, many patrons are either unable or unwilling to participate in an instruction session. Just as we use technology to make electronic resources available to our patrons no matter where they are physically, we also need to use technology to provide instruction on how to best use those resources. Some methods of instruction include creating screen casts and other online tutorials, blogs, or wiki pages, integrating library instruction into online courses (using Blackboard or WebCT), and chat reference. The demand for faster service by library patrons has exploded within the last decade. Patrons want immediate access to electronic resources available worldwide. With the implementation of ILLiad, Ariel, and Docutek, the Resource Sharing Center at Western Michigan University focuses on meeting the needs of our academic community for materials not readily available to them. Technological advances have changed the structure of resource sharing. The electronic environment has provided immediate access to our users. From placing a request at anytime to viewing articles electronically, faculty, students, and staff can better meet the expectations for educational achievement and research. Additional services, such as document delivery for faculty and the provision of pdf copies from off-site storage material have been enabled with the efficiencies resulting from technical advancements. The necessity for team approach is never more apparent than when viewing the interaction needed to address all aspects of electronic resources and libraries in serving our patrons
