In the example below, the present tense provides a little more drama:
Will Ken finish the presentation? Will Corby rephrase his question to
get it through Ken's thick skull? Will Dr. Gupta dismiss the whole
discussion as "not compelling"? Compare:
"Ken drones on about the DFT. Next he looks confused as Corby asks
about the DCT. Finally, Dr. Gupta suggests we take the discussion off
line and move on to another topic."
"Ken droned on about the DFT. Then he looked confused as Corby asked
about the DCT. Finally, Dr. Gupta suggested we take the discussion off
line and move on to another topic."
On the other hand the problem with using the present tense is that it
is easy to slip into the past tense, since the events happened in the
past.
I would be interested in learning if there is such a choice or
distinction in Krishna or Guofeng's native language.
In terms of correctness of the class summary I suppose it would be
better to use the past tense, especially considering that we are
describing an event for the historical record. Of course Dr. Gupta
also is looking for more discussion and exploration in the summary,
but that's a separate issue. :-)
At the same time, in my view the goal of communication is to get your
intended meaning into the consciousness of the listener. Following
"the rules" is an aid to understanding, but the bottom line is to do
whatever it takes to impart your meaning.
I think this goal is critical in our class presentations as well as
the summaries. In the example of my DFT presentation, I could have
described it better by taking an example time-domain equation and
working through the DFT transform frequency by frequency. Preparing a
presentation is a race against time. First we must learn the topic
ourselves, internalize and rearrange it in our own minds, and then
explain it clearly to the listener. Unfortunately, I'm usually in the
"internalize and rearrange" stage when I have to make the
presentation. :-( This class has been great practical experience in
working through this problem.
