LTI v1.3 Tool: student can not change language in a multilingual course

[markkuriekkinen]

If a multilingual (Finnish and English study materials) A+ course is used via the LTI Platform (Moodle), then the student has no UI for changing the language of the A+ course. If the student has visited the course in the real A+ site, the language selected there would be active in the LTI view as well. The LTI view does not include the UI for selecting the course language.

• Should the LTI view include the language selection UI?
• Should the LTI view enable language based on the LTI launch parameters? (Is there a standard LTI parameter for the language?)
  • (Moodle has its own language selection. Is that language sent in the LTI launch parameters?)

The existing A+ LTI Tool code already sets the LTI language parameter to the user profile, but that does not select the language in a multilingual course. The course-specific language selection is saved in the Enrollment model.
