*In this series of posts, we’re highlighting questions we’ve found on the public Numbas editor which do something innovative or are of particularly high quality.*

In this question, Dann Mallet ofÂ QUT very effectively integrates a video from his course to remind students of the rules of complex arithmetic before testing them on some basic operations.

It’s really easy to include a video in a Numbas questionÂ – Dann has uploaded his recording to YouTube, then embedded it in his question statement using the “embed video” button in the editor (there’s a screencast in the online Numbas docs showing exactly how).

We asked Dann how he uses Numbas in his teaching:

I’m the Director of Learning and Teaching for Mathematical Sciences at Queensland University of Technology (Brisbane Australia), as well as teaching students of mathematics, engineering, science and education degrees. Part of my directorial responsibilities is knowing about, testing and encouraging others to use innovative technologies for teaching mathematics. This is how I got onto using Numbas – I’m working to push us from a reliance on WeBWorK to Numbas, which I find to be more friendly to “creative” teachers. So far, I’ve only managed to play around with numbers to give my students some outside of class time activities to work on.
