Off-tangent: modern lectures are still a better way to learn something than original lectiones were ― the lecturer would read the book by some prominent author, and students would listen to it and take notes... and that's it. That's what lectio literally means: "[an act of] reading". And before the invention and spread of the printing press, it absolutely made sense ― books were rare and expensive.

Today, of course, lectures during which the lecturer simply reads the textbook and does nothing more, are rightfully considered to be the worst: a student too can read the textbook himself just fine!
