YEN-JIE LEE: I think chalkboard is much more natural for the students and for me because if I write all the equations on the slides, first of all, all those equations appear at the same time. And so it is actually harder for the student to follow the logic between formulas.

And my feeling is that it is so much naturaler to see all those equations popping up in a logical sequence for them. And by writing down them on the chalkboard, people have time to think as well, what is actually happening. And I have also the freedom to point to the relevant equation on the board slowly so that people, everybody who is not very familiar with the mathematics can follow.

Factorial x squared, plus V triple prime 0 divided by 3 factorial x to the third, plus infinite number of times. And the V(0) is the position of where you have minimum.

So I think that's actually a decision to use chalkboard in combination with slides. Usually, my slides contain information which is actually already covered from the previous lecture. So that serves a purpose to flash through the information which is actually already covered duirng the last few lectures, to remind people that, OK, you have learned this before. Right? And so I don't have to waste a lot of time to copy them on the chalkboard because they already learned that.

And secondly, I can use slides to include interesting figures, interesting videos, interesting pictures, et cetera, so that it should be that is complementary to my chalkboard teaching style.
