"modest". Statistically significant? How were controls made to ensure
these differences? How did they know the remote students were
actually "watching" the presentations? This is not a very good study
if those controls weren't in place.
And if they only changed the content delivery part and nothing else
that comes with an online system, they aren't comparing the two
systems, just a part of each system.

Our truest response to the irrationality of the world is to paint or
sing or write, for only in such response do we find truth.
