### I. What is WeBWorK ?

WeBWorK is a system that allows students to do their homework in an interactive web-based environment.

Using WeBWorK, students may try to answer homework problems more than once. After each try, a message appears telling the student whether the answer is correct or not. This provides immediate feedback to the students, allows them to discover what they did wrong, and hopefully allows them to understand the topic of the question better.

Each WeBWorK problem set is individualized. Each student has a different version of a problem generated from a fixed template; for example the numerical values in the formulas may be slightly different).

### II. How to use WeBWorK to do your homework

Using WeBWorK is quite simple.
Below are the basic steps on how to get started.

NOTE: Most pages of WeBWorK also contain directions. Therefore, if you are ever unsure of what you should do, try reading the directions and descriptions on the page at which you are looking.

1. You can use any computer with a browser like Netscape or MSIE. In general, it is not possible to use a text-based browser like lynx since most of the mathematics is rendered using a graphic format.
2. Open Netscape and go to the main WeBWorK page of our class, address http://webwork.dartmouth.edu/webwork_1.8/m8s03/.
3. To log in, click on the 'Login' button.
4. This will take you to a login page. Enter your login name and password, and click on the 'Continue' button.
Your login name is the usually just your last name, followed possibly by a digit for people in the class with the same last name (e.g. smith, smith2, ...)). Possible exceptions include compound last name like "den Hartog" or "De La Huerta" which would be rendered Hartog and Huerta respectively
5. If your login is incorrect, you will be told so, and you can return to the login page and try again.
6. If you are registered for the course, you should receive and email from your instructor confirming your login and password.
If your login is correct you will see a page where you can do following:
• Look at and do the problems in a set via Netscape.
To do the first days assignment, for example, click on the line in the box that starts with 's03day1'. Then click on the 'Do problem set' button.
On each line in the box, where all the sets are listed, after the set number, you can see whether the set is open or closed. If the set is open, that means that when you solve a problem, it will be counted towards your grade. If the set is closed, you can still solve problems, but your results will not be recorded.
After the indication of whether the set is open or closed, there is additional information about the due date (if the set is open), or whether the answers are available (if the set is closed).
• Get a printout of the problem set.
To print out s03day1, for example, first choose the download type. The default of pdf is probably what you want, although you may have to configure your browser to use Adobe's Acrobat Reader to view (and print) the files. If you want to work with postscript, you can save it to your desktop and (on a mac drag it to a printer icon). To view postscript, you will need to install ghostscript (see the software page on the Mathematics Department's web site.
After choosing one of the download types, click on the line in the box that starts with 's03day1...'. Then click on the 'Get hard copy' button. A couple of things may happen at this point. If your browser is set up to handle pdf documents, your browser window will fill with the homework set in it as a document. In this case, go to the icon 'file' and choose the 'print' option. If your browser is not properly configured, you may get an alert message asking what to with the file. In this case, you can save the file to disk (so that you can print it at a later time), choose an application to view or print the file (e.g. GSview or dropPS for postscript or Acrobat Reader for pdf). Any of the computer consultants show be able to help you with this kind of problem.

• Look at a summary of your WeBWorK homework scores.
This is the second section of the page. If you click on the button 'Get Summary', you will see your current scores for all available problem sets.

7. If you are printing out a problem set or looking at a summary of your homework scores, you are done. If you are viewing a problem set via Netscape, you will see a page with the problems in the set you chose. To view and/or answer a problem, click on the number of the problem and click on the 'Get Problem' button. Notice that there are three modes of viewing the problem: 'text', 'formatted-text' and 'typeset'. It is best to view the problem using 'typeset' mode, which should be the default. Once you choose a problem and click on the 'Get Problem' button, you will see the text of the problem with boxes for your answers. Enter your answers and click on the 'Submit Answer' button. If you are working on a problem set that is already closed, you will have the option to see the correct answer or a solution if one is available (currently only a few problems have solutions available). To see the correct answer and/or solution, just check the box(es) and click on the 'Submit Answer' button (you do not have to enter an answer to see the correct answer or solution). Once you have submitted an answer, you will be told whether your answer is correct or not. If not, you can try again. After you've tried a problem, you can either go to the next problem, the previous problem, or see the list of the problems again.
8. If you want to check the status of your problems (e.g. to double check that your answers have been recorded), use the "Prob. List" button at the top of the page to see the problem list page.
9. When you are finished, log out using the "Logout" button at the bottom of the page.
10. That's all, folks!

### III. Important facts to know

• What to do if you have problems with WeBWorK:
• If you have a problem logging in, contact your instructor.
• If you have a problem printing out a set, ask a consultant at a computer lab. If you don't get sufficient help, contact your instructor or TA.
• If you have questions on specific homework problems or if you have comments about WeBWorK that you think can help us make WeBWorK better, click on the 'Feedback' button on any of the pages of WeBWorK.
• If you are logged on to WeBWorK for longer that 30 minutes without any activity, you will be asked to log in again. This is a security measure. You can resume your work after you logged back in. All your results from the last log in will be saved.
