Physics Demonstration Videos
These videos have been developed for different elementary physics courses (including this one) and have been very instrumental when those courses had to be taught in a fully remote format.
More videos, that may be not as useful as from the list, are available here, and here.
The department web site http://physics.bu.edu/demos/ also has some video demonstrations; the indicator of a video is letter V in the description of a demo (see an example below).
For publications on strategies for teaching STEM courses follow to this website.
