WeBWorK
(WW) is a
system used to create weekly problem sets for Math 131. You
submit your answers online. After you submit an answer, WW
tells you immediately whether
your answer is correct or not. You
can resubmit answers to questions as often as you like, without
penalty, up until the closing time for the problem set. This allows you to go return to your
work, figure out what you did wrong, and, we hope, understand the
question better.
WeBWorK is a learning tool for students and ultimately it functions on the "honor system." Certainly, you may help each other with ideas or hints on the problems. But, in the end, you're supposed to solve the problems yourself and submit your own
answers. Frequently WW randomizes information among individual problem sets, so someone else's
numeric answer might not work for the corresponding problem in your personal homework set.
Doing
a problem for somebody else, or having someone give you an answer to
submit, just intereferes with learning opportunities.
The points you
earn in WW don't
contribute all that much to the overall course grade, and any "WW payoff" you
get from someone solving a problem for you is probably less
than the cost (on a test) of not learning how to do the
problem.
If there are any indications coming through the WeBWorK system or
otherwise that you are not submitting your own work, it may treated as an academic
integrity violation.
You
should go to the WebWorK page
(and probably "bookmark" it on your computer for the semester).
From this page, select the link for Math 131 and logon to WeBWorK.
First Time Logging On Your default username and password are the same  your 6digit WU
Student ID Number. When you log on for the first
time, you
should immediately:  Change your password
 Use the menu to update your email address, if necessary. This will let me or the WebWorK coordinator respond to any message you send us from within WebWorK.
 What if I forget my password? Send a message to webwork@math.wustl.edu or email your
instructor who can also reset your password. The should happen within 24 hours, but maybe much quicker.
WeBWorK is easy to use, and many of your initial questions can probably be answered on one of the following pages.
Otherwise, email your instructor.
There is a set of "WWPractice" that will become available on Monday, August 29, for optional practice. These problems will let you review some precalculus material that we are not going to discuss in
class, and they will let you practice entering answers in WW. Generally, the syntax is very much like
what you would use on a graphing calculator  for example, x^2
is entered
to
represent x^{2} and sqrt(x) is used to represent "the
square
root of x."
NOTE:
the set WWPractice may say that it's "closed." That's just to keep WW
from recording a score for you on this set of problems. You can still
open it, print it, look at each problem, enter your answers and
hit the "submit" key to see it it's correct or not. Your can also
"show correct answer" if you like. Any solutions you submit (or
don't submit) for the questions in this review set will not be
counted toward your WW score for the course.
At 12:01 a.m. on Tuesday, September 6 the first real WeBWorK problem set
WW1
will "open"  meaning that you can start work
after that time. Probably the best strategy is to open WW1
and print out a pdf copy for
yourself to work with until you're ready to submit answers.
When you enter answers for some or all
problems, WW will tell you immediately whether you're correct or incorrect. If a solution is wrong, you can try again and resubmit
an answer as many times as you like up until the HW1 deadline at
11:59 p.m. on the following Monday, September 12. At that
time, WW 1 will automatically close online and WW 2 will open
up a few minutes later. There
will probably be about 15 problems, so don't wait until the last
minute. Also, try to avoid entering information just short of the
deadline: remember, your watch is probably not be quite synchronized
with the computer's clock.
Sometimes WW might mark a numeric answer wrong because of roundoff errors. Therefore it's safer not
to convert answers into decimals unnecessarily. Instead, you
can enter expressions sqrt(2), or cos(pi/7), or 113/217
in your answers without evaluation, and WW will do it's own evaluations
of these expressions behind the scenes.
If
you
can't figure something out and your friends can't help, send me an
email. And, FOR WW, PLEASE: the best way to email the
instructor is to use the
link "Send message to instructor" from the particular WW page where
you're trying to submit an answer. When I get that message, WW lets me
immediately open to that problem in your personalized problem set. Of course, I'm not monitoring emails 247, but I'll reply as soon as I can.
The typical pattern for WeBWorK
assignments
throughout the semester will be "Assignment opens at 12:01
a.m.Tuesday and solutions are due by 11:59 p.m. the following Monday,
but there will be a few exceptions due to Fall Break and Thanksgiving
holidays. These exceptions are posted in the Daily
Assignments page.
At
the end of the semester, your two lowest WeBWorK scores will be dropped, and the remaining WeBWorK scores will be converted to
a percentage = your WEBSCORE. WEBSCORE will be 10% of your grade in the
course.
