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.
