Expand settings to enable adaptive learning environments

1 Initial Problem

The learning module has the potential to be used to create adaptive learning environments.

The idea behind adaptive learning environments is that every following action is a result of how each individual student performes in the current action. For example, if a students answers a question incorrectly, they are (via a link in the feedback) directed to a second question on the same topic. If they answer incorrectly again, they are directed to an input page so they can review the material. From there, they are directed to question 1 again so they can try again. If they answer incorrectly, the same cycle begins all over. If the answer correctly, they are directed to the next topic. This pattern is repeated until the student worked through the environment.

There are two main issues with the learning module as an adaptive learning environment:

1. Navigation options can't be disabled, so students can navigate to wherever they want in the learning module rather than following the path intended for them. 
2. When limiting the number of tries for a question, the correct answer is automatically displayed after reaching the maximum, which makes engaging with the learning material again redundant for the student.

2 Conceptual Summary

To solve the problem, the settings for the learning module and the settings for questions need to be expanded:

Settings for the learning module:

The dropdown menu for "Table of Contents Items" needs a third option: "none". With this option, there will be no navigation tree on the left side of the learning module. This option should simultaneously deactivate the arrow navigation in the presentation view. This way, students won't be able to navigate to pages they shouldn't be able to get to. 

Settings for questions:

A selection list (radio buttons) should be added to the "Number of Tries" option in the question settings where the admin can choose whether or not the correct answer will be displayed after the student reached the maximum number of tries.
Options:

a) show correct answer after last possible try
b) do not show correct answer after last possible try

If b) is selected, the option "Disable Default Question Feedback" in the settings of the learning module needs to be activated, because the default feedback for final incorrect answers contains a note that the correct answer is shown above. 

3 User Interface Modifications

3.1 List of Affected Views

• … { Please list titles of all views (screens) of ILIAS that should be modified, newly introduced or removed. }

3.2 User Interface Details

{ For each of these views please list all user interface elements that should be modified, added or removed. Please provide the textual appearance of the UI elements and their interactive behaviour. }

3.3 New User Interface Concepts

{ If the proposal introduces any completely new user interface elements, you might consult UI Kitchen Sink in order to find the necessary information to propose new UI-Concepts. Note that any maintainer might gladly assist you with this. }

3.4 Accessibility Implications

{ If the proposal contains potential accessibility issues that are neither covered by existing UI components nor clarified by guidelines, please list them here. For every potential issue please either propose a solution or write down a short risk assessment about potential fallout if there would be no solution for the issue. }

4 Technical Information

{ The maintainer has to provide necessary technical information, e.g. dependencies on other ILIAS components, necessary modifications in general services/architecture, potential security or performance issues. }

5 Privacy
