Multimedia material for teaching physics (search, evaluation and examples)

Finding multimedia material for teaching physics worldwide would seem to be easy at first glance, since there is now a lot of material available. But on closer inspection it becomes obvious that (apart from standard topics) it is very difficult, if not impossible, to find excellent teaching materials. Several representative databases are collected and described here. Only a few of them use an evaluation scheme to judge their content. If the material is evaluated, every organization uses its own list of criteria with its own weaknesses and strengths. Therefore we want to initiate a discussion to finalize a standardized evaluation scheme and to make this available to physicists and physics teachers.This paper finishes with two multimedia examples we have produced ourselves: about diffraction and about Michelson interferometry.
