| The Open University has asked me to work on this now.
| | I started working on this in October 2009. |
| | |
| Since this involves API changes it would be really nice to do it in Moodle 2.0. However, that may be unrealistic. When I expect this to be finished and when the Moodle 2.0 stable branch is created are currently both around the end of 2009, and it is impossible to say which will come first.
| |
| | |
| I will be implementing this as a branch in git, so the decision of which Moodle version to put it into can be made later.
| |
|
| |
|
| ==Relationship with OU Moodle==
| | It was committed to the OU's CVS repository on 1st October 2010 and will be released live on the OU VLE at the start of December 2010. |
|
| |
|
| One of the drivers for doing this is to reduce the differences between the OU's version of the quiz, and the standard version. This has gradually grown to the point where it can be considered a fork.
| | The next stage is to merge the code into standard Moodle after Moodle 2.0 is release, so it can be included in Moodle 2.1. That work is happening now. |
|
| |
|
| The [[Development:quiz_navigation|quiz navigation improvements]] that are already in Moodle 2.0 were the first half of the un-forking.
| | You can follow development at http://timhunt.github.com/Moodle-Question-Engine-2/. |
|
| |
|
| The second change that needs to be merged into Moodle core is our replacement of the old Adaptive mode with the new Interactive mode. We originally did that while trying to make minimal changes to the quiz code, and the pain Mahmoud experienced while doing that was one of the things that got me thinking about this new design.
| |
|
| |
| However, because of that history, I first need to implement the new code in the OU's version of Moodle. Then I need to incorporate it into Moodle 2.0. I am proposing to do that by first back-porting all the other Moodle 2.0 quiz changes to the 1.9 branch (but don't panic, they will not be committed to the stable branch in CVS!). Then building a new version of OU Moodle quiz on top of that base, then putting the new code into Moodle 2.0. That will not be fun, but it is the way it has to be.
