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

That students cannot view the page source

Answer

That MathJax is disabled for mobile users

Answer

That equations are stored as images rather than LaTeX

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

The randomization is working correctly

Answer

Seeds are being ignored by the server

Answer

The problem requires a restart to fix

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

Using only graphical answer boxes

Answer

Requiring Flash-based rendering

Answer

Disabling keyboard navigation

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

Delete all affected problems

Answer

Warn students not to enter zero

Answer

Change all fractions to whole numbers

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

Immediately assign it to students

Answer

Archive the original OPL files

Answer

Disable randomization for the first week

Question 6

In a WeBWorK improvement cycle, which data source provides the most actionable feedback about specific poorly-performing problems?

Accepted Answer

Per-problem statistics showing attempts, scores, and completion rates

Answer

Student end-of-semester surveys

Answer

Server uptime logs

Answer

Course enrollment numbers

Question 7

Which WeBWorK setting controls how many attempts students have before an answer is marked incorrect permanently, and is critical to QA for fairness?

Accepted Answer

Max attempts per problem

Answer

Reduced scoring period

Answer

Open date

Answer

Showwork mode
