I’ve just released v1.5 of Numbas on Github. While there have been loads of changes since the last time I remembered to bump the version number up, the biggest change recently is that I have rewritten the default theme to use the knockout.js framework. It makes the underlying code a lot simpler, and allows us to do a few new things that would have been very complicated. In particular, there is now a Review mode which is made available when you have finished an exam – you can click on any question on the feedback page to go back to it and compare your answers with the expected answers, as well as seeing any marking feedback and the model solution in the Advice section.
The version numbers in the Numbas source code repository don’t mean too much since we push updates to the stable branch as soon as they’ve been tested instead of lumping them together, but it’s good to mark progress every now and then.
The mathcentre editor tracks the stable branch, so you can try the new features there now.
The Review mode was something we had in the previous system we used at Newcastle, and it was the one thing that many of the students asked for in a survey conducted at the end of the first semester by Dr. Nick Parker. I’m glad it’s finally in Numbas!
