Numbas

Releases

Development update: October 2020

I went from paternity leave in September straight into the mêlée of our first entirely online semester. Here’s an update of development work on Numbas during the month of October.

The vast majority of changes are bug fixes, now that so many more people are using Numbas and discovering edge cases. (And I made a couple of mistakes when introducing Numbas v5, sorry!)

Development update: August 2020

We’re continually working on Numbas, fixing bugs and adding new features. I thought that it would be a good idea to post more regularly about updates to the Numbas software, rather than waiting until each year’s major version release to list everything that’s changed.

I’m going to go into a bit more detail on changes than I normally would in major-release posts, to give an idea of what day-to-day development on Numbas looks like.

I’d like these posts to be monthly, but I’m about to embark on a month of paternity leave, so don’t expect another one until the end of October.

So, here’s what’s changed since Numbas v5.0 was released in June.

Numbas LTI provider v2.7

We’ve just released a minor new version of the Numbas LTI tool provider.

Changes in this version include:

  • A global dashboard view, showing resources which are active today.
  • An option to only show completed attempts when viewing the statistics for a resource.
  • When the student ends their attempt, they’re shown an encoded receipt which they can use as evidence of their score, even if no receipt email is sent.
  • Bug fixes around time zone handling, sending email receipts on attempt completion, cross-site security and text formatting.

We recommend updating any servers running the LTI provider as soon as possible, by following the upgrade instructions.

The installation instructions for Ubuntu, Red Hat Enterprise Linux and Heroku have all been updated.

Numbas v5.0

It’s time for another major version of Numbas. This release includes a radically new way of presenting questions, as well as a few other helpful new features.

We’ve made a short video to demonstrate the new features:

We’ve also made a demo exam so you can try it out yourself.

Out now: Numbas v3.0, the marking algorithms rewrite

Today we’ve released Numbas v3.0. It’s the thing I’m second-most proud of producing in the last year (my daughter was born last October).

The marking code at the heart of Numbas has been completely rewritten, to make it much easier for question authors to change how students’ answers are marked. This has also allowed the introduction of custom part types, to make it easier to use and reuse different marking algorithms.

Development log: March 2017 – Usability improvements

We’ve made a few changes to Numbas and the editor recently, with the aim of improving usability. It involved moving some parts of the editor around, so I thought I’d better show what we’ve done.

First of all, when you submit an answer to a part of a Numbas question, the input changes colour depending on the score you were awarded. (If you’ve got score feedback turned off, it turns the same colour no matter how you did)

Here’s an example:
