Die Folge haben wir am 23.04.2020 aufgenommen.
Intro & Feedback
A hatte angenommen, dass O sich das ausgedacht hat, aber tatsächlich: es gibt den „No“-Button bei TimeTex. Wenn Ihr mögt, sprechen wir Euch noch andere Dinge CC0-lizenziert ins Mikrofon (nur Jugendfreies, A kann auch sächsisch). Vorbild: die Stimme der Honest Trailers bei den Screen Junkies.
Dank des Feedbacks von Achim Birkner haben wir nun die „sinnlose Grafik“ aus dem letzten Paper+A richtig einordnen können und mögen es jetzt irgendwie doch sehr 🙂 .

News+O
- O hat jetzt doch ein Mittel gegen die „Corona-Langeweile“ gefunden: Arbeit!
- Er hat Lightning-Talks für die ausgefallene Edunautika aufgenommen und für die Edunauten ein Webinar zu H5P gegeben. Andere Projekte sind dafür etwas liegen geblieben.
- Für H5P ist auch Zeit: „Pick the Symbols“ hat nochmal zugelegt, „Scavenger“ geht voran. Der H5P-OER-Hub wurde zwischenzeitlich von Joubel angekündigt.

abstract = {Learning with hands‐on experiments can be supported by providing essential information virtually during lab work. Augmented reality (AR) appears especially suitable for presenting information during experimentation, as it can be used to integrate both physical and virtual lab work. Virtual information can be displayed in close spatial proximity to the correspondent components in the experimentation environment, thereby ensuring a basic design principle for multimedia instruction: the spatial contiguity principle. The latter is assumed to reduce learners' extraneous cognitive load and foster generative processing, which supports conceptual knowledge acquisition. For the present study, a tablet‐based AR application has been developed to support learning from hands‐on experiments in physics education. Real‐time measurement data were displayed directly above the components of electric circuits, which were constructed by the learners during lab work. In a two group pretest–posttest design, we compared university students' (N = 50) perceived cognitive load and conceptual knowledge gain for both the AR‐supported and a matching non‐AR learning environment. Whereas participants in both conditions gave comparable ratings for cognitive load, learning gains in conceptual knowledge were only detectable for the AR‐supported lab work.},

Mit “Augmented Reality”-Werkzeugen kann man die echte Welt visuell mit künstlichen Dingen überlagern. Man könnte beispielsweise in Experimenten mit elektronischen Schaltkreisen die verwendeten Bauteile mit Angaben zu an ihnen gemessenen Werten anreichern: Spannung, Stromstärke, usw. Bringt’s auch was beim Lernen? Dem ist ein Team aus Saarbrücken und Kaiserslautern nachgegangen.

In this work, we examine the effectiveness of debunking on Facebook through a quantitative analysis of 54 million users over a time span of five years (Jan 2010, Dec 2014). In particular, we compare how users usually consuming proven (scientific) and unsubstantiated (conspiracy-like) information on Facebook US interact with specific debunking posts. Our findings confirm the existence of echo chambers where users interact primarily with either conspiracy-like or scientific pages. However, both groups interact similarly with the information within their echo chamber. Then, we measure how users from both echo chambers interacted with 50,220 debunking posts accounting for both users consumption patterns and the sentiment expressed in their comments. Sentiment analysis reveals a dominant negativity in the comments to debunking posts. Furthermore, such posts remain mainly confined to the scientific echo chamber. Only few conspiracy users engage with corrections and their liking and commenting rates on conspiracy posts increases after the interaction.},

Man braucht nur genügend Fakten, um Verschwörungstheorien und Schwurbel den Wind aus den Segeln zu nehmen, oder? Wie reagieren User auf Posts, die Fakten klarstellen? Die Autorinnen und Autoren dieser Studie haben sich durch 5 Jahre Facebook-Posts gearbeitet, um diese Frage zu beantworten.
Fundgrube+Alt+Entf
Projekte, Tools, Apps… das sind doch bürgerliche Kategorien. Wir packen einfach alles in die Fundgrube:
- O hat die Zusammenstellung von A zu Statistiken rund um Corona ganz gut gebrauchen können.
- A hat eine neue Sammlung zu Spielen für Videokonferenzen begonnen.
- Im Podcast Bildungsfern berichtet Marco Bakera als Berufsschullehrer von den Entwicklungen an seiner Lehre und an seiner Schule.
- Ähnlicher Ansatz, anderer Bildungsbereich: Die DHBW interviewt mit dem Podcast Studium im Shutdown Studierende und wie sie die aktuelle Situation erleben.
- Die Gastronomie trifft es gerade hart. Auf PayNowEatLater kann man mit Gutscheinen dafür sorgen, dass es sie nach der Pandemie vielleicht noch gibt. Solche Hilfsangebote gibt es in vielen Städten (bspw. HLfen.de in Lübeck).

Veranstaltungstipps
- 24. und 25. April 2020: EduCamp Frankfurt im Internet (#ecfra20)
Spart Euch die Anreise und schaltet Euch zum ersten digitalen EduCamp dazu. Das Corporate Learning Camp hat es vorgemacht, wir glauben, das wird gut.
- 06. bis 08.Oktober 2020: University:Future Festival
Das Hochschulforum Digitalisierung hat sein Festival im Herbst bereits als Online-Veranstaltung angekündigt. Es wird sicher bald einen Call dafür geben.

Die Gesellschaft für Freiheitsrechte versucht mit strategischen Klagen dafür zu sorgen, dass die Grundrechte von Bürgerinnen und Bürgern nicht weiter eingeschränkt werden. Ganz frisch ist das Projekt control ©, mit dem die ehemalige Europaabgeordnete Julia Reda die Umsetzung der Urheberrechtsreform begleitet.
