I should probably have posted about this here before now. It is the usual excuse of busy-ness.
A group of us are trying to get together plans to re-develop the question bank in time for Moodle 4.0, to fix the long-standing problemes (as exemplified by some recent posts here,
and I am sure you have seen many more.)
As we get further in our planning, I will post more details here, because I want as many people as possible to look at what we are suggesting, and tell us if it seems to make sense. However, detailed plans have not been made yet.
What has been happening is that I have presenting the general idea to various groups (Moodle developer meeting this morning, MUA town-hall events - there is another on of those this evening. Moot US, ...). If you want to watch one of those, I suggest the Moodle developer meeting one. It is the most detailed one so far. Earlier in the process we talked about our plans at the Global Moot Online, and Moot DACH.
The 'We' behind this project are me, Luca Bosch (who you may know from the Moodle bug-tracker, because he fixes a lot of quiz-related bugs, Thomas Korner (current MUA chair) and Antonia Bonaccorso (colleague of Thomas at ETH Zürich).
The approach we will take to this project is based on the modle that successfully delivered better SEB integration in Moodle 3.9. That is, a group of institutions to get together and crowd-fund one of the Moodle Partners to do most of the development. If your organisation may be able to help with that, please complete this survey.
The reason we are proposing this now is because of Moodle HQ's decision to delay the release of Moodle 4.0 to November 2021, so there is more time to make bigger changes.
