Interactive with explanation question behaviour
This can be installed from the plugins database at https://moodle.org/plugins/qbehaviour_interactiveexplain
The source code can be found at https://github.com/marcusgreen/moodle-qbehaviour_interactiveexplain
This plugin is based heavily on Tim Hunts deferred feedback with explanation question behaviour. https://moodle.org/plugins/qbehaviour_deferredfeedbackexplain
It requires that this plugin https://github.com/marcusgreen/moodle-local_qbehaviour_interactiveexplain is also installed
This behaviour is like the interactive with multiple attempts behaviour, but with an additional text box where students can give a reason why they gave the answer they did. No attempt is made to automatically grade the explanation, nor is it required. However, it may be used in various ways, for example
The teacher may want to manually edit the grades where the student gave a wrong answer, to give partial credit if the student used the right method or approach. The student might want to explain their thinking, so that later, when the results and feedback are revealed, they are reminded of what they were thinking at the time, and so can reflect more deeply. Note: 3rd party question behaviours do not work with the mobile app and there is no API at the moment to allow for that.
Appearance for students
The explanations given can be seen by the user or teacher after quiz submission by reviewing the quiz as in this screen shot.
This plugin has a requirement that a companion local plugin local_qbehaviour_interactiveexplainis installed to configure strings and behaviour. This can be accessed at yourmoodle/admin/settings.php?section=local_qbehaviour_interactiveexplain
This is because question behaviour settings cannot be stored via a settings.php file in core moodle. There is a ticket to address this at some point in the future. https://tracker.moodle.org/browse/MDL-68335
