Linked parameters in formula questions

1 Initial Problem

With the formula question ILIAS provides a task type that allows randomized tasks. The given variables of the task can be limited within a min/max range as well as on the basis of a divisibility rule. The results to be determined by the students are stored in the form of a formula depending on the given quantities. For more complex tasks, not all randomly generated combinations of given quantities are useful. Here a linkage of the individual parameters would be desirable.

2 Conceptual Summary

In addition to purely random parameter generation, a list could be given for each given quantity (e.g. parameter v1 =[ 1 2 3], v2 = [ 4 5 6]). For each task run, a list index is now randomly determined. This ensures that if v1= 1 then v2= 4. The length of the list must be identical for all parameters.

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

{ Please list all personal data that will need to be stored or processed to implement this feature. For each date give a short explanation why it is necessary to use that date. }

6 Security

{ Does the feature include any special security relevant changes, e.g. the introducion of new endpoints or other new possible attack vectors. If yes, please explain these implications and include a commitment to deliver a written security concept as part of the feature development. This concept will need an additional approvement by the JourFixe. }
