SQ3R Revamped is more modern and effective, IMO: Survey, Question, Rephrase (Feynman method), Recall (Active Recall) and Repetition (Spaced Repetition). Shortly, Survey, Question, Rephrase and Spaced Retrieval (S-Q-R-SR).
Spaced retrieval, yes! I need to talk about spaced repetition on my channel. :) There are oodles of spin offs or alternatives to SQ4R, with some pros and cons perhaps to each. Ultimately it the user who has to decide what works best for them and adapt as needed.
Hi there! Thanks for the questions. SQ4R was made for actively reading (anything, really). For listening to lectures (or youtube or audio), you can try a different method, such as the Cornell method. I recently made a video in that.
I like music when I watch RU-vid, and I suspect others do as well. You cannot please everyone, I guess. I will take your very direct feedback to heart, though, cheers.
