Good morning class,
Just a reminder, Maria has office hours by appointment on Fridays and
scheduled office hours on Tuesdays:
TA: Maria Tafur, email: firstname.lastname@example.org, 405 Chem Sci; office
hours Tuesdays 4:30-6:30, Fridays by appointment.
The best preparation for the final (and Exam 4) is to work through
problems. If you are having some difficulty, I recommend that you
work through problems and make an appointment to see Maria to get some
feedback on your methods.
To study in engineering, here is my suggestion: use the worked
problems in the texts as "tests," that is, try to do the problems
without looking at the solution. Reading through the solution is
not the same as doing the problem as a "test". If you read
through a problem, you have seen it done, but you have never faced
those critical moments when it is hard to decide what to do next.
It's like watching snowboarding on TV and then going to the top
of Mt. Ripley because you "know how to snowboard". I think we all
agree that watching it done by an expert is not the same as doing it,
although it's a way to start. After watching it once (lecture)
the best next step is to try easy problems on your own (snow board on a
gentle hill, fall, get up, try again), and then gradually work your way
through harder problems.
I recommend a "strip tease" approach. Look at the problem but
cover up the solution. Do the problem. If you can do it,
fabulous. If you cannot, peek at the solution, but don't read the whole
thing. Just see what critical next step you're missing. Go
back to solving the problem without looking. Keep doing this
until you are done with the problem. If you had to peek, put the
problem away and do it again the next day. Do this over and over
again with the same problem until you do not need to peek to do that
Imagine if one had followed this path for Exam 3 preparation.
Possibly you would have done the pressure-driven flow in a tube
problem a few times. Maybe you would have done the U-bend problem
a few times. Such a preparation would have given a very good
result on the exam. And if the problems you practice are not on
the exam, you would still have done well because you would have
practiced figuring out what the next step is. That's what we're
trying to learn.
Again, please make use of Maria's office hours. Maria is very
smart and she can help you learn how to problem solve in transport.
My office hours are as usual, Mondays 4:30-6 and Wednesdays
4:30-5:30. I am also happy to help, but sometimes there's a line.
