Diversität und Neue Medien als didaktisches Prinzip

Hochschulen sehen sich in ihren Bemühungen um mehr Attraktivität und Internationalität ihres Studien- und Forschungsangebotes geänderten Wertvorstellungen, Lebensstilen und Interessen der Studierenden gegenüber. Zudem spielen mit dem Wandel von der Informations- zur Wissensgesellschaft Informations- und Kommunikationstechnologien in der Hochschullehre eine wachsende Rolle. Diesen Anforderungen müssen Hochschulen gerecht werden. Sie müssen auf den Wandel bzw. auf die Innovationen reagieren und im Rahmen modularisierter Studiengänge neue Lehr-Lernkonzepte entwickeln, die der Neuausrichtung von der Input- zur Outputorientierung sowie dem Shift from Teaching to Learning gerecht werden und für die Entfaltung von Kompetenzen Sorge tragen, welche lebenslanges Lernen ermöglichen. Zentral ist, die Studierenden selbst, ihre Vorkenntnisse, Lernstile und Erwartungen, d.h. ihre Diversität in den Mittelpunkt hochschuldidaktischer Bemühungen zu rücken.  11.08.2010 | Karoline Spelsberg (Essen

Junge Hochschul- und Mediendidaktik. Forschung und Praxis im Dialog

Am 29./30.05.2012 fand in Hamburg die Konferenz “Junges Forum Hochschul- und Mediendidaktik” (JFHM) statt. Ausgerichtet vom Zentrum für Hochschul- und Weiterbildung (ZHW) der Universität Hamburg, kooperierten bei der Konzeption und Durchführung der Tagung Vertreterinnen und Vertreter aus hochschul- und mediendidaktischer Berufspraxis mit Vertreterinnen der wissenschaftlichen Nachwuchsförderung aus der Deutschen Gesellschaft für Hochschuldidaktik (DGHD) und der Gesellschaft für Medien in der Wissenschaft (GMW). Das Ziel der Tagung war die Sichtbarmachung und Vernetzung theoretischer und praktischer hochschul- und mediendidaktischer Arbeit. Der vorliegende Sammelband vereint Beiträge der Konferenz und gibt so einen Einblick in aktuelle Themen von Hochschul- und Mediendidaktik - und zwar speziell aus der Perspektive jüngerer Forscherinnen und Forscher sowie Praktikerinnen und Praktiker. Er gibt damit auch Anhaltspunkte dafür, welche Themen diese Arbeitsbereiche in Zukunft (weiter) beschäftigen werden. (DIPF/Autor

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.
