samigo: Feature request: Allow Immediate feedback but DON'T allow student to change answer after viewing feedback

An instructor would like to create a self-assessment for students where a student responds to a question, then they are presented with immediate feedback before they move to the next question. They cannot change their answer to a question after viewing feedback for that question. The instructor who requested this feature says she's used something similar in Blackboard.

I propose the following:
For Linear Access assessments ONLY, make an additional feedback option available:

• Allow feedback during the assessment, after viewing each question. Note: If a student clicks the Feedback link while viewing a question, feedback is shown and they can no longer change their answer.

This could be presented to the instructor in the samigo Settings page as follows:

• In Grading and Feedback, when the assessment Navigation is Random Access (default), the new option is shown, disabled, with the text: To enable this option, in Layout and Appearance, change Navigation to Linear access to questions with NO return to previous pages.

• In Layout and Appearance, the instructor selects Linear access to questions with NO return to previous pages.

• Instructor can then return to Grading and Feedback and select the option to Allow feedback during the assessment, after viewing each question.

• Underneath this new feedback option, a set of options, Release question and the following after viewing a question, would need to become active for the instructor to select which types of feedback to enable during the test-taking process. (Note: The instructor may want to release only correct/incorrect answer feedback after the student views the question, and not the overall assessment score, e.g.)

For the student:

1. Student begins assessment and views question.

2. If the student clicks the Feedback link, regardless of whether they have entered any response, they'll see the feedback and all answer options will become inactive (selections grayed out, text box no longer editable, etc.) There would also need to be a clear WARNING: Clicking Feedback will prevent you from changing your answer to this question! The Feedback link should also be moved down on the page, BELOW the input for the question, so that screen reader users do not encounter it before they respond to the question.

3. The student will need to move to the next question to continue the assessment.
