I have to come back with a few annoying facts.
a) Many teachers buy a significant portion of the teaching materials themselves (even before Corona) and some have, as a matter of course, bought a camera. In some poor municipalities, school books are not provided for teachers either, but have to be purchased.
b) Well-intentioned is not yet well done. If even a single student does not have the technical possibility to participate in a video stream, legally(!) nothing new may be done in video lessons. Principle of equal treatment. This degrades the tool in such cases to pure work hours and a video stream from hybrid lessons is excluded.
c) Many schools do not even have a sufficient internet connection to stream from the rooms.
d) You cannot transfer the usual teaching 1:1 to video conferences. Certain forms of interaction are not available. You need a different kind of teaching – one that, especially in primary schools, is more occupational therapy than a developmental offer and one with which there is still little experience.
e) The own initiative. The teachers who organize themselves in various video formats with a (by the way very likeable to me) “don’t give a damn” attitude are gambling on the card “no plaintiff, no judge.” Legally, it is not always clean. Parent initiatives tend to collapse because of legal conformity, not because of the will of the teachers. To ascribe an excessive legal conformity to a state employee would be somehow… well, nonsensical.
f) At least at secondary schools, grading “if necessary” (that is, at the latest in case of a complaint about a grade) requires complete documentation that can exclude technical problems on the student's side. Such a thing is practically impossible to do but fills some funny work hours pointlessly.
g) IT at schools. Usually done by teachers with affinity on the side. Accordingly, the results often are. The alternative is the one (in numbers: 1) employee of the municipality who, despite an IT degree, ended up at an E10 pay grade in an authority (nothing against E10, but on this labor market?) and now supports ALL schools in the municipality. Work speed: hardly measurable
