The sections are created on the edit quiz page, and then appear in the
navigation panel when the quiz is being attempted to help students find
their way around.
The 'Shuffle questions' setting has been moved from being per-quiz
to being a per-section.
This commit is actually the joint work of Mahmoud Kassaei and Tim Hunt
from The Open University. We could only use one persons name for the
commit and this time Mahmoud gets the credit/blame.
This feature is designed for use on pracice or formative quizzes.
It is available for quizzes that use Interactive or Immediate feedback
behaviour.
If the teacher turns this on in the quiz settings, then once a student
has finished a question, they get a 'Redo question' button beside the
question. If they click it, then the question they finished is replaced
by a new one so they can try again to practise that particul skill or
bit of knowledge a bit more.
When randomisation is involved, the studnets will be given a question or
variant that they have not seen before if possible.
This patch adds completion options to Quiz similar to what is available in scorm.
One can have the quiz marked complete when either a passing grade is achieved or
all attempts are used up. This will allow a quiz to complete when the user "passes
or fails". (Where "fail" means "using up all attempts without passing".)
The sequence of questions that made up a quiz used to be stored as a
comma-separated list in quiz.questions. Now the same information is
stored in the rows in the quiz_slots table. This is not just 'better' in
a database design sense, but it allows for the future changes we will
need as we enhance the quiz in the MDL-40987 epic.
Having changed the database structure, all the rest of the code needs to
be changed to account for it, and that is done here.
Note that there are not many unit tests for the changed bit. That is
because as part of MDL-40987 we will be changing the code further, and
we will add unit tests then.
This data should all have been upgraded when moving to Moodle 2.1. It
was only kept as a back-up, and now, after 3 years have past, we can
clean it up.
Some columns needed to be renamed:
* quiz -> quizid
* question -> questionid
* grade -> maxmark
Then all the places that refer to those needed to be fixed.
* Support for old non-standard cron for quiz reports dropped. (Standard
cron support was added in 2.2
* Cron support added for qbehaviour, qformat and quizacces plugins.
* qtypes were already supported in the standard way.
This was implemented by Matt Petro of the University of Wisconsin - Madison Engineering
School and Math Department. Many thanks. Reviewed by and committed by Tim Hunt.
This adds a new Overrides tab to the UI, with sub-tabs Group overrides and User overrides.
Each of those lists all the overrides that currently exist, and lets you manage them and
create more.
When a quiz is being attempted, the override that applies to the current user is combined
with the current quiz settings loaded from the quiz table (normally called $quiz).
If there are both user and group overrides, then just the specific user override is used (more specific).
If the user is in several groups, then the overrides are combined to give the most permissive set of options.
There is one new database table quiz_overrides, to store the overrides.
* Reorder form fields to group things more logically.
** and on the corresponding admin page too.
* Set some options to be 'Advanced' by default:
** Apply penalties.
** Each attempt builds on the last.
** Decimal places for question grades.
** The five 'Extra restrictions on attempts' settings. (password, etc.)
* Admins can still change this to suit their institiution at Administration > Plugins > Activity modules > Quiz.
* These new defaults are applied if the admin had not previously set any fields to be advanced.
* Disable some filds when they are not applicable:
** Grading method, if num attempts = 1
** Penaly scheme, if adaptive mode = no
** Each attempt builds of last, if num attempts = 1
** Review after quiz closed options, if no close date.
** Delay between 1st and 2nd attempts, if num attempts = 1
** Delay between later attempts, if num attempts < 3
* Convert quiz.timelimit to be in seconds, for consistency, and ready for the new duration field type (MDL 18500).
** Including ensuring that backup and restore is backwards compatible.
* MDL-5537 New setting, questiondecimalpoints, so, for example, you can show the quiz grade as an integer, but have fractional question grades.
** There is a 'Same as overall decimal points' option, which is the default.
* Improve some field labels.
* Make corresponding changes in the help files.
