These homeworks are to be written on a piece of paper (with your name, recitation section and ID number)
and handed to your recitation instructor in the specified week. You must write not only the answers but
also your reasoning and explanation, which must be written clearly enough so that the grader should be
able to follow your reasoning. Answers without explanation will get only parital credit.
The best way to access WebAssign is through
Blackboard. From within Blackboard, click on the
link for your MAT 131 recitation (not lecture!). Then go to the left panel, go
almost all the way to the bottom, and click on "Tools". Finally,
scroll all the way to the bottom of tools and click on
"WebAssign". That should automatically log you into your WebAssign
At the beginning of the semester there is a 2 week "grace
period" during which you may access WebAssign without an access
code. But within the first 2 weeks you are required to purchase a
WebAssign access code (either bundled with a textbook, or as a
stand-alone access code, whichever you prefer). Without a
WebAssign access code, you will not be able to continue accessing
WebAssign. That means you will not be able to complete the
You can access the web interface
from any computer with Internet access and a recent
web browser (the computers in the
SINC sites, for instance).
When you first access the WebAssign account, please go to the
My Options page (in the upper right of the
screen) and put in your email address.
After they are assigned,
the online problems may be completed
anytime before the assigned deadline. You can look at problems online,
print them out, work on them as long as you like, and then answer
them in a later Internet session (before the deadline).
The online problems are automatically graded with
The online problems are of different types; some
are short answer and some are multiple choice. There are different
problems and different variants of the same problem.
Different students will be assigned different problems. So do not try
to compare your answers to another student's answers.
The WebAssign assignments will be due at 9am on Wed (for all sections of MAT 131). Late submissions will not be accepted except in cases of emergency. Questions answered early (before 9am on Monday) will get 5% early submission bonus.
If you got the answer wrong, you can retry it. However, you with each wrong answer you are losing points: getting the answer right on the 1st try gives you full credit, getting it right on the second try gives you 1/2 of the credit, getting it right on the 3rd try gives 1/3 of the credit, etc.
Doing the Assignment
WebAssign has a variety of different question types, ranging from multiple
choice to fill-in-the-blank to symbolic questions. Here are some things to
keep in mind as you work through your assignments:
- Some questions require entering symbolic notation. Answer symbolic
questions by using calculator notation. You must use the exact
variables specified in the questions. The order is not
important as long as it is mathematically correct. Clicking on the
eye button previews the expression you enter in proper mathematical
notation. Clicking on the symbolic formatting help button provides
tips for using the correct keystrokes.
- When you click on some WebAssign math questions an input palette will
open. This palette, called mathPad, will help you enter your answer in
- You can save your work without grading by selecting the Save Work
button at the end of the question. After you save your work, it will be
available to you the next time you click the assignment.
- Please note that WebAssign will not automatically submit your answers
for scoring if you only Save your work. Please be sure to Submit prior to
the due date and time.
- You can submit answers by question part or for the entire
assignment. To submit an individual question answer for grading, click the
"Submit New Answers to Question" button at the bottom of each
question. To submit the entire assignment for grading, click the "Submit
All New Answers" button at the end of the assignment.
- Some WebAssign questions check the number of significant figures in
your answer. If you enter the correct value with the wrong number of
significant figures, you will not receive credit, but you
will receive a hint that your number does not have the correct number
of significant figures.
- While different students may get slightly different versions of the
assignment, your questions will be the same every time you return. This
means you can print out the assignment, work the problems, and then come
back later and put in your answers. Since you get multiple attempts to
get the question correct, be sure to leave yourself enough time to rework
the problems that you did wrong.
- Each question is (typically) worth one point. If a question has
multiple answers, each of those are worth a fraction of a point.
- If you put in a wrong answer for a question and ask to have it graded,
you will be told it is wrong and be ably to try again. However, if you
put in the correct answer on the second try, you get half credit. On the
third try, you get 1/3 credit, and so on.
- If you have issues with the assignment, you can use the "Ask your
Teacher" button to send a message to your TA and/or lecturer. You should
make it clear which problem you are talking about, and what, specifically,
your issue is. Using "Ask your teacher" is prefered to sending an email
because your question gets saved with your assignment.
