Degrees of Certainty with student feedback (deferred)

A question behaviour derived from Student feedback (deferred), where students can submit their certainty about their answers, and one comment for each question and one comment for the whole Quiz, after their attempt is submitted.
Installation
This plugins is based on the qbehaviour_studentfeedbackdeferred plugin, and needs it to be installed.
With this question behaviour, students can submit for each response given in the Quiz their degree of certainty (DC) that their answer will be judged correct. A mixed scale with 6 DC is used, associating percentages and text.
Here is an example for a True/False question:
After the Quiz, the results are presented using a color code according to the combination of the answer (correct / incorrect) and the degree of certainty:
The report page that is displayed (and that remains available for review) contains:
– a summary of the results that is given in form of a histogram:
– detailed feedback for each question using the same color code:
Like the “Student feedback” behaviour plugins, this plugin also integrates the possibility for the learner to enter metacognitive comments, at two levels:
– just below the histogram (see screenshot above) to leave an overall metacognitive comment,
– after each detailed feedback, question by question (see screenshot above), to leave a metacognitive explanation about their answer.
Important note
Please note that the provided certainty levels have no impact on the mark given for each answer, and is not planned to do so in any future version.
This plugin’s goal is to allow learners to give metacognitive information about their answers, and not be evaluated on them.
Whether you choose to include this information in your evaluations or not is at your discretion.
Setup
Once installed, simply go to a Quiz settings > Question behaviour > Select “Certainty with student feedback (deferred)”.
