## I. What is WeBWorK ?

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

UsingWeBWorK, 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.

EachWeBWorKproblem 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 anybody can try out WeBWorK

Anyone with an internet connection can try out WeBWorK by following the directions in Part III below and using the

Guest Loginbutton at the bottom of the login page.

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

Using

WeBWorKis quite simple.

Below are the basic steps on how to get started.

NOTE:Most pages ofWeBWorKalso 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.

- You can use any computer with a browser like Firefox, Opera, Safari, or MSIE. A note of caution is the IE on the Mac may have some issues with secure pages, so if problems arise, try another browser.
- Open your browser and go to your
WeBWorKcourse page: https://webwork.dartmouth.edu/webwork2/m8w11.- On that page you will find the necessary information about logging in.

To log in, enter your login name and password, and click on the 'Continue' button.

Yourlogin nameis 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.

Your initialpasswordis (unless you gave me something else) your six-character student ID ``number''.- If your login is incorrect, you will be told so, and you can return to the login page and try again.
- If you are registered for the course, you should receive an email from your instructor confirming your login and password prior to the first day of classes.

If your login is correct you will see a page where you can do following:

Change your password and email address

You should probably change your password since it initially set to your student ID number which is relatively sensitive data. You shouldnotmake it your BlitzMail password unless you always use a secure connection (https) and don't typically login on public computers to do your homework. If you forget your password, it can be reset, but perhaps not for 24 hours.

Look at and do the problems in a homework set.

To do the first day's assignment, for example, click on the line in the box that starts with 'setw11day1'.

Each line listing the homework sets will indicate 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.

Most likely you will want to print a hardcopy of your problem set so that you can think about the problems and work out the solutions before you sit down at the computer to enter your answers. To print out setw11day1, for example, select the button next to its listing and click on thedownload hardcopy button. This will take you to a new page where you can tweak things and then press theGenerate hardcopybutton. You will need a pdf reader (e.g. Acrobat Reader) to view the file, but most of you should have that already.

Look at a summary of your WeBWorK homework scores.

If you click on the button 'Grades', you will see your current scores for all available problem sets. Generally there is no additional information.

- 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 your web browser, you will see a page with the problems in the set you chose. To view and/or answer a problem. Notice that there are various modes of viewing the problem: 'plainText', 'formattedText' and 'images', and so on. It is best to view the problem using 'images' mode. Enter your answers and click on the 'Preview Answer' or 'Submit Answer' button.
The

Preview Answeris extremely useful to verify the expression you have entered is what you really intended. Thesampleset is one in which you can practice entering expressions.

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.- 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.
- When you are finished, log out using the "Logout" button on the left side of the page.
- That's all, folks!
