As everybody else, educators in STEM fields are transferring their teaching online. But a lot of teaching involving mathematics still relies heavily on handwriting. This is much less straightforward to replicate in a video let alone a live Zoom call. There are several obvious options:
But all of these require additional technology plus the adjustment to new software and a different feel of the digital pen. Particularly, the graphics tablets take a lot of getting used to.
But for those who would like to continue using pen and paper to teach online, Alan Morrison, Professor of Law and Finance at the Business School figured out an ingenious way of using his iPhone as a visualiser that can be recorded or simply chosen as the video source for a Zoom call. The entire set up cost about £30. Below are the slightly edited instructions he shared for replicating his set up.
Note: An alternative solution with MS Teams in mind is written up in the Teaching Remotely resource by the Oxford Mathematical Institute who also have Android-based instructions.
This assumes that you have an iPhone or iPad but it should work with Android, as well.
Zoom has a built-in feature that makes it possible to share an iPhone or iPad screen directly into the call. This essentially replicates what Airserver does. That works well but the iPhone or iPad has to be connected every time screensharing is started so it is a bit disruptive if you need to stop and start screen sharing during a live session. If you share the screen throughout, Zoom will function as Airserver.
Note: You don’t even have to run a live session to use Zoom to record. It is even possible to do this with the free version of Zoom as long as the recordings are shorter than 40 minutes.
It is important to have good lighting. A normal desk lamp may be enough but it’s best to have one that casts a white as opposed to yellow light.
Having a lamp from each side would help cancel out shadows but another option is to point the light at a white surface (such as a wall) nearby which will diffuse the lighting more evenly.Back to top of article
