I didn't read the research paper, so maybe they do this, but I think an emphasis needs to be placed on the specific subject having notes taken on.

I think hand written notes for math is just a no-brainer situation. Math formulas do not translate well to typing. Programming courses though? Probably a bit of a different story.

Additionally, I'd be interested to know if the learning is improved when talking about how much info is retained from that lecture period versus after studying the material noted down. I've been experimenting with taking typed notes and using an AI model to generate anki cards for me from those notes. So far it has been quite useful.
