Accepted Answer

PDCA (Plan-Do-Check-Act) cycle

Answer

Waterfall development

Answer

Big Bang implementation

Answer

Critical path method

Question 2

A WeBWorK department coordinator wants to standardize QA across multiple instructors' courses. The best approach is to:

Develop a shared QA checklist and review protocol for problem set deployment

Answer

Require all instructors to use identical problem sets

Answer

Restrict problem creation to one designated instructor

Answer

Disable the problem editor for non-admin users

Question 3

When a WeBWorK system update changes the MathJax version, the primary QA concern for existing problems is:

Accepted Answer

Whether existing LaTeX in problems still renders correctly after the update

Answer

Whether student passwords need to be reset

Answer

Whether problem due dates shifted

Answer

Whether the gradebook exports to a different format

Question 4

Which QA indicator most strongly suggests that a WeBWorK answer checker is accepting incorrect answers?

Accepted Answer

High completion rate combined with low subsequent exam performance on the same topic

Answer

Long average time-on-task for the problem set

Answer

High number of help requests submitted by students

Answer

Low enrollment in the course section

Question 5

For quality improvement of WeBWorK hint text, which criterion is most important?

Accepted Answer

Hints should guide students toward the method without giving away the answer

Answer

Hints should reveal the complete solution step-by-step

Answer

Hints should be written in formal mathematical notation only

Answer

Hints should be identical to the problem statement

Question 6

A WeBWorK admin is performing QA on server performance during peak submission windows. Which metric is most critical to monitor?

Accepted Answer

Response time for answer submission requests under peak concurrent load

Answer

Total disk space used by problem files

Answer

Number of instructor logins per day

Answer

Database backup frequency

Question 7

Which WeBWorK QA practice helps prevent scoring inequity when randomized problems have variants of significantly different difficulty?

Accepted Answer

Testing multiple seeds and revising the parameter space to ensure uniform difficulty across variants

Answer

Giving all students the same seed

Answer

Awarding bonus points for harder variants

Answer

Disabling randomization for graded assignments
