I’m taking a Coursera class, and the videos show an instructor facing the camera while talking. He writes on the “screen”, using his right hand, and the notes appear correctly (also facing me) as if drawn on a glass window between us. How is this accomplished without him actually writing backwards a la Da Vinci? He is clearly writing on something board-sized.

The presenter is writing on a piece of glass with the camera looking through, so the raw video will have the text reversed.
They just flip/reverse the clip and like magic everything is the right way round.
Think of it like taking a selfie using a mirror. The image in your phone is backwards, but if you look at the image using the mirror it is all good.
