I actually hope more teachers go for the simple overhead option. I do, using an overhead webcam. A physical overhead with the instructor's hand visible has been shown to work far better than presenting ready-made diagrams. It also work

Gaze guidance actually appears to be pretty important [1]. For drawing diagrams, a physical overhead with the instructor's hand visible seems to work far better than digital drawing [2]. [1]: https://doi.org/10.1016&#
