Tested as an LTI provider: Moodle versions 3.9.6 plus 3.9. plus 3.11+
Tested as an LTI receiver: Moodle versions 3.9.6+ plus 3.10.4
Good afternoon all,
After many hours of methodical and extensive testing, where we have tested with and without other plugins being installed so as to eliminate those as a possible causes, we believe we have revealed a bug.
Here's what we've found.
In brief, the moodle text editor is removed from the question answer box (essay question with response format set to 'HTML Editor' ) when the question is presented to the candidate. If the candidate manually formats their answer by inserting new lines for paragraphs e.t.c. and then submits their answer, the manual formatting is not saved in the moodle database.
This makes it difficult for the markers of the question to read, and therefore is both time consuming and annoying which can result in standardisation errors in the manual marking.
We set the question format to HTML Editor, because we want the candidates to be able to format their answers, but it doesn't seem possible.
The problem only occurs when a combination of two moodle settings are applied.
The quiz is delivered as an LTI activity
The quiz has a 'duration' time set (i.e exam lasts 60 mins e.t.c.)
If we switch off the quiz duration, the problem goes away, but the duration is important for our examination scenario.
We believe this to be a bug in the core moodle that has not been raised by anyone else therefore we will raise it on Moodle Tracker, but first I'd welcome others from the community to follow our testing procedure to verify our diagnostic outcome.
See the video below for an illustration of the problem.
