Mit MOOCs aus den Hochschulen war die Welt doch (noch) nicht gerettet, Sozialwissenschaftler*innen werden nicht begeistert der AfkM (Alternative fĂĽr konservative Metriken) nachlaufen und Kartoffeln machen unglĂĽcklicher als Smartphones...
Die Folge haben wir am 23.01.2019 aufgenommen.
Wir wĂĽnschen Euch wahlweise ein frohes oder gesundes neues Jahr (gern auch beides)!
The same procedure as every Episode: Dank an Stammhörer Martin, der das IG-Nobelpreis-Paper, das wir in Folge E009 vorgestellt haben, bei Methodisch Inkorrekt wieder erkannt hat. Für die Kollegen von BZT hat O noch weitere Bildungspodcasthörempfehlungen: Bildungsshaker, 42, Podcampus und via FYYD findet man sicher noch einige mehr (A hat aber auch beim Shownotes schreiben nicht herausbekommen, wofür fyyd steht – vermutlich ist es einfach nur phonetisch ähnlich zu Feed…? Sonst weiß das Internet doch auch immer alles!).
Schöner Döner

Die Autoren haben alle MIT- und Harvard-MOOCs auf edX von Oktober 2012 bis Mai 2018 statistisch ausgewertet. Drei Muster ließen sich über die 565 Durchgänge von 261 Kursen erkennen: Die meisten Lernenden sind nach einem Jahr nicht mehr auf der Plattform, die Lernenden kommen fast ausschließlich aus wohlhabenden Ländern, und die Abschlussquote hat sich in den sechs Jahren nicht verbessert.

Bibliometrische Kenngrößen wie der Journal Impact Faktor (JIP) oder der Hirsch-Index (h-Index) versuchen die Relevanz von wissenschaftlichen Publikationen oder wissenschaftlichen Autorinnen und Autoren in Zahlen auszudrücken. Meist geht es darum, was wie häufig zitiert wurde. Seitdem man wissenschaftliche Paper auch im Web veröffentlichen kann, kommen immer mehr sog. Altmetriken hinzu, also Kenngrößen wie Download-Zahlen oder Likes in sozialen Netzwerken.
Die Sozialwissenschaften schneiden bei den traditionellen Metriken nicht allzu gut ab. Dennoch scheinen die Wissenschaftlerinnen und Wissenschaftler auch die alternativen Ansätze meist nicht zu kennen und ihnen auch zu misstrauen: Sichtbarkeit in Social Media kostet schließlich Zeit, in der man “richtig forschen” könnte und dort ohnehin nur schwer präzise und faktenbasiert diskutiert werden könne.
Wie man es auch dreht: hier müssen alle mal etwas aufgeschlaut werden, damit die Metriken richtig interpretiert werden – oft genug werden sie zur Erfolgsmessung herangezogen, obwohl sie einige Schwachstellen haben.

Manche sogenannte Wissenschaftler*innen behaupten in ihren Büchern und in Talkshows, digitale Medien machten Jugendliche unglücklich. Das hat nun ein Team aus echten Wissenschaftler*innen genauer untersucht: Ergebnis: Es gibt tatsächlich einen negativen Zusammenhang, der aber bloß 0,4 % (Null-komma-vier Prozent) des Wohlbefindens erklärt – fast denselben Wert erzielt das Essen von Kartoffeln.
