You can do scoring from the web. This can be done by any user with professor permissions, and can be done from either the Hmwk Sets Editor or the Scoring Tools. You can either score one set at a time, or get a total score for multiple sets. The scoring procedure creates files (in .csv format) that include the status of the problems, the number of attempts, and also the final score of the problems. Then:

  • You can download these different files onto your personal computer clicking on the file names on this page, or from the File Manager.
  • These files can be used within WeBWorK to automatically send students personalized email to inform them of their scores and/or other scoring data.

Using the Scoring Tools to Export Homework Set Scoring Data to a CSV file

By default, to export homework set scoring data to a CSV file you must be logged in as a professor. To change this permission level requirement (for example, to ta), the change must be made in the global.conf file. In particular, this permission level cannot be changed in Course Configuration.

When logged in as a professor click the link labeled Scoring Tools. This link can be found in the WeBWorK main menu under Instructor Tools.
(Click Scoring Tools.)
At the top of the scoring tools page you will be presented with an interface through which you may
  • select one or more homework sets to score,
  • select or deselect options to Include Index, Record Scores for Single Sets, and Pad Fields, and
  • choose a name for the file in which to save the scoring data.
  • To score one set select it and press the Score Selected Set(s) button. To score multiple sets, highlight them and press the button; this will create a "totals" file which combines the scores from all of the sets to give final scores.

The three options available function as follows:

  • Include Index adds a second column for each homework set; the second column reports the Success indicator for the corresponding set for each student.
  • Pad Fields adds spaces within the fields of the scoring file. This displays nicely as HTML, but may cause trouble when importing the scoring file into a spreadsheet application. It is checked by default, and it is recommended that you un-check that option to produce a file for use in a spreadsheet application such as Open Office Calc or Excel.
  • Record Scores for Single Sets creates the totals file, but also creates two additional files for each homework set selected:
    • s<SetName>scr.csv containing the status of each problem in the set for every student, and
    • s<SetName>ful.csv containing the information in the previous file and additionally the number of correct and incorrect attempts on each problem in the set for every student.
Select Sets to Score
After clicking the Score Selected Set(s) button, the exported CSV file(s) will be available to download.
  • By defalut, the totals file will be named <CourseName>_totals.csv. In the example shown, the course was named "1300_sp09" and so the default name of the totals file is 1300_sp09_totals.csv. You may change this name if you wish. However, you are advised to leave the extension ".csv" or your computer may not know which application to use to read the file.
  • A link to download each file will be available on the Scoring Tools page.
  • These scoring files, along with back-up copies of any older scoring files, are accessible from the File Manager.
Click "Score Selected Sets and Save to" button
