Just a short note to report I have uploaded a new version of the formulas question type for Moodle 2.3 to my github account.
I expect this version to be less buggy than the previous one .
I would be interested in bug reports, mainly about the display using various behaviours.
There are so many feedbacks in this question type that maybe I should explain what each one is used for
General feedback : as usual the only thing specific is that global variables are allowed and will be replaced by their value.
Combined feedback : I must underline that this feedback is related to the question as a whole not to each question's part (subquestion).
In adaptive and interactive with many tries behaviours this feedback is displayed after each check/try.
Global variables are allowed and will be replaced by their value.
Part (subquestion) feedback : there is one such feedback for each question's part. This is the only feedback where not only global but also local variables for that part are allowed and will be replaced by their value.
IMPORTANT: As discussed some month ago this feedback is only displayed if the student answer for this part is wrong !
Hint: Only used in interactive with many tries. The only specific thing to the formulas question type is that global variables are allowed in hints and will be replaced by their values.
Part grade display: when using adaptive behaviour, a grade for each part is displayed after each response check. It's in fact not a feature of the formulas question type but of Tim Hunt's adaptive multipart behaviour that you must install to be able to install the formulas question type.
In all other behaviours (including interacrtive with many tries) there is no grade display for each question part, only a global grade for the question .
But in interactive with many tries behaviour the "Clear incorrect responses" and "Show the number of responses" are available with each hint .
I must one more time emphasize that this is a work in progress and not ready in my opinion to be used on a production server. And also that a lot of feature are still missing : upgrade from Moodle 1.9 or 2.0, restoration of course backups made by Moodle 1.9 or 2.0.
The only goal of this message is that "motivated" users can help me to iron out as much bugs as we can before adding the remaining missing features.
As you can guess this question type is very complex and rewriting it for the new question engine is a big task (In fact now that I know the complexity of the task, I wonder whether I should have undertaken it , but it's too late, and I really think that the worst is behind me !)
