WeBWork Quality Assurance and Improvement 3

Question 1

When conducting QA on a WeBWorK problem that uses MathJax rendering, which of the following should be verified?

Accepted Answer

That all LaTeX expressions render correctly across major browsers

Answer

MathJax rendering must be verified across major browsers because rendering inconsistencies can cause students to see malformed equations.

Question 2

A WeBWorK problem generates randomized parameters but two different seeds produce identical problems. What does this indicate?

Accepted Answer

The random parameter space is too small or constrained

Answer

Identical problems from different seeds indicate the parameter space is too narrow, meaning the randomization provides insufficient variety.

Question 3

Which QA practice helps ensure WeBWorK problems remain accessible to students using screen readers?

Accepted Answer

Providing alt-text for images and using semantic HTML where possible

Answer

Alt-text for images and semantic HTML are essential accessibility practices that allow screen readers to convey problem content to visually impaired students.

Question 4

During QA review of a WeBWorK problem pool, an instructor finds that 30% of problems have a randomized parameter that can produce a zero denominator. The best fix is to:

Accepted Answer

Add a condition to exclude zero from the denominator's possible values

Answer

Adding a conditional exclusion for invalid parameter values (like zero denominators) is the correct fix and preserves problem randomization integrity.

Question 5

What is the recommended QA step after importing a new OPL (Open Problem Library) problem set into a WeBWorK course?

Accepted Answer

Preview each problem and test answer submission before assigning

Answer

Previewing and testing each problem confirms it renders correctly and the answer checker works as expected before students are exposed to it.
