LTI Questions and Answers

Baird Whelan -

What are the Lumen External Tool/LTI Apps?

Lumen supports 3 types of courses with the following configurations:

  1. Waymaker - Lumen Platform (basic launch LTI), Lumen Waymaker (used for the Study Plan functionality), and Lumen OHM (used for calculations in courses like Microeconomics)
  2. Candela - Lumen Platform only
  3. Lumen OHM -Lumen OHM only

Is the LTI key/secret unique to an institution, domain, or course?

  • Our LTI allows you to access the appropriate domain (e.g. courses.lumenlearning.com, ohm.lumenlearning.com) for the particular course.

  • When you add the External Tool at the Admin/System Level, it allows the course cartridge import to automatically connect and verify access thereby providing a relatively seamless experience for the teacher and student.

  • The LTI key/secret is unique to the institution, and we want it to match all *.lumenlearning.com domains. D2L requires specific sub-domain entries, so we use the same key/secret for each External Tool.

Do you send grade values back?

  • It depends on the type of course (Waymaker and Lumen OHM = Yes, Candela = No)

Do you provide a course cartridge (import package) for every course? Is the cartridge unique to a course?

  • The number of cartridges and their need to be unique depends on whether teachers are adopting or adapting (e.g. editing) a course.
  • Candela courses are generally a ThinCC.
  • Waymaker courses are delivered as native course cartridges, depending on the LMS (e.g. Brightspace/D2L gets a Brightspace/D2L course file, Blackboard a Blackboard course file, and so it goes...)

How does Lumen use the Security Fields? 

  • Send user ID to tool provider:
    This is the unique ID we use to determine who the user is across multiple LTI launches.

  • Send user name to tool provider:
    The teacher has a dashboard that shows each student's progress and scores and the student's name.

  • Send user email to tool provider:
    The teacher can choose to send emails to the students via Waymaker about questions they missed on their quizzes.

  • Send system username to tool provider:
    This is not directly used. It is useful in cases of debugging problems, since this is usually a human-readable unique identifier for a user.

  • Send system Org Defined ID to tool provider:
    We use this for scoping permissions and data to a school.

  • Send system role to tool provider:
    Admins, teachers, and students have different interfaces and permissions. We base that on their role in the LMS. If no role is sent we assume they shouldn't have access.
