User Stories

This is a list of basic tasks desired by WeBWorK users (Students, instructors, administrators, etc.), as motivated by [1]. The intention is for this document to motivate back-end and API development.

Note that this is not intended to be a list of current functionality. It is a list of tasks that users desire to be able to do in the system.

Please feel free to add any missing tasks to this list.

  • Import users from a file
  • Update a student's information (login, email, name, id number, password, etc.)

  • List all students in a given section / recitation
  • Assign problem sets to one or more users

      • Suggested solution: When resetting a global due date a pop-up window warns if there are any individual overrides. The instructor has a chance to adjust these individual extensions or not as the situation warrants.

Authors

• obtain data about common errors on a problem, perhaps gathered only from courses on an MAA site
• digest of student queries/complaints/praise (a selection of Email Instructor items)

Developers

• Add a feature to webwork. E.G. Add the achievement system or some other feature which interacts with webwork in a non trivial way and requires persistence in such a way that it doesn't break installations of people who aren't using the feature.

• Automated assignments for students taking placement tests
• Sharing of problem pools
• (Easy generation / inclusion of additional tables: meta-data about problem pools, how to define student groups, ... so that these can be shared across institutions and installations of WeBWorK)
• Model courses
• Master courses (e.g. institution standard course, assign assignments from master course to specific course)

extended comments

• A course-level schedule object could allow flexibility for an Instructor's tool to provide flexible management of dates for assignments together with associated actions.
  • dates for a single assignment (some selection/extension of the following)
    • visible to students
    • open
    • dueDate
    • date to show answers
    • date to show solutions
    • date ending opportunity for bonus credit
    • date ending opportunity for reduced credit
  • flexible management of dates
    • specify which event (previous list) has explicit calendar date
    • specify delta-times for all other events (allowing "infinity" to hide all solutions from all students)
    • specify fractions for bonus or reduced credit
    • to simplify reuse of a course, allow use of a meta-schedule specifying just dates for the controlling event (but also allow revision of that during the term)
    • select alternatives for summarizing the configuration to students (e.g., show text about dueDate together with icons indicating alternative credit stuff)
  • interface should clarify hierarchy for configuring this complexity, perhaps extra tab in Course Configuration which modifies course.conf as a record within an archived course
