I would like to open for discussion the idea of adding competencies to quiz question as a base for much deeper ability to map student's knowledge and skills found in each question to a competency proficiency report and if you will a "Standards or Objectives report" (see: MDL-21977) that can help the student and the teacher understand what competency need more practice.
We have already made some progress with this, but we need your insight to see that when we add it into core Moodle it can help a wider community.
We added support for attaching course competencies to quiz questions, as we wish to display a report to teachers about each of their students failing to gain proficiency with specific competencies when failing specific questions that are related to each other, in a quiz.
We have also developed a "Follow up activity suggestion" wizard the recommend to teachers what follow up resources and activities can help improve student's understanding and proficiency after they "failed competencies" that were attached to questions in that quiz, so we can enable specific students (using Restrict Access) to be engaged with future activities and resources (following the quiz) that can help them better understand those competencies they failed to understand.
Looking forward for your insights about this new feature development.
I have uploaded the suggested patch to: MDL-64989, so please feel free to add you feedback here or at the tracker.
