We now compute the average CBM score, accuracy, CBM bonus and enhanced
accuracy, both for the entire quiz, and for just the questions answered.
Note that these calculations must work correctly in the presence of
descriptions, ungraded questions, and manually graded questions. For
example, imagine a essay added at the end of the quiz "Summarise what
you learned attempting this exercise." This might have max mark zero or
non-zero. The CBM statistics just ignores questions like that.
At the top of the quiz reivew page, there is a table that summarises
infomration about the quiz attempt as a whole. For some question
behaviours, we would like to be able to add additional information to
that summary.
This commit introduces a generic method for the behaviour to provide
summary information about an entire question usage.
It was always a bit of a hack to use static methods on the
qbehaviour_whatever classes to return metadata about the behaviour. It
is better design to have real qbehaviour_whatever_type classes to report
that metadata, particularly now that we are planning to add more such.
For example, inheritance works better with real classes. See, for
example, the improvements in
question_engine::get_behaviour_unused_display_options().
This change has been implemented in a backwards-compatbile way. Old
behaviours will continue to work. There will just be some developer debug
output to prompt people to upgrade their code properly.
This plugin is heavily based on the uploadpdf plugin from
Davo Smith <git@davosmith.co.uk>. This is a fantastic plugin
that provides a great benefit for teachers marking assignments.
A big thankyou to Davo for writing the plugin and helping us to
get it integrated to core.
The plugin provides a pdf editing interface in the teachers browser
that lets them add comments and annotations to a students assignment
submission. The comment and annotations are then added to a pdf version
of the students submission which is send back to the student so they can
download it, or read it online.
This plugin has been primarily worked on by Damyon Wiese, Jerome Mouneyrac
and Barbara Ramiro. We have also had great feedback and suggestions from others
including the entire frontend team, Martin and Frederic Massart.
Adding following events related to feedback responses:-
/mod_feedback/event/response_deleted
/mod_feedback/event/response_submitted
/mod_feedback/event/instances_list_viewed
/mod_feedback/event/course_module_viewed
as well as for first or all attempts.
This commit drops a database table and then recreates it. This is in
order to be able to have some new columns in the table be NOT NULL with
no default value, which would not be possible if I added fields to an
existing table.
The quiz_statistics table is used for caching calculated values only
and thus we can safely drop it and recreate it.
