Please read before closing as a duplicate of: Maths Education Questions
I am wondering specifically about the process of Math education; I was recently considering showing Grant Sanderson's (3blue1brown) videos on linear algebra to a student; and I am wondering on the efficacy of using videos for Math education, as opposed to 'old school' pen and paper, or even techniques to interface the two styles.
This question does not have to do specifically with decomposing a math concept; but it is about Math education itself.
Is this appropriate for this site?
