VoiceThread Docs / VT in your Learning Management System / LMS Administrators / Jenzabar

What is LTI?

LTI is an abbreviation for Learning Tools Interoperability, which is a standard protocol developed by 1EdTech. It allows services like VoiceThread to integrate with your Jenzabar environment as single-sign-on tools.

The resulting experience for instructors and students is simple:

  1. Sign in to your Jenzabar account.
  2. Navigate to your course.
  3. Click on the VoiceThread LTI link.
  4. Use VoiceThread.

Clicking on a VoiceThread LTI link will authenticate the user, establish an account for him if he didn’t have one already, and enroll him in his course within VoiceThread. No additional work is required from the instructor or student.

LTI Tool Configuration

Before instructors can use VoiceThread, it must be configured globally for your Jenzabar instance by an administrator.

  1. Navigate to the Admin Console -> Global Portlet Operations -> Learning Tools.
  2. Click “Add a new Learning Tool”.
  3. Name the configuration (for example: “VoiceThread”).
  4. Enter your Provider URL: https://yourdomain.voicethread.com/ltione/
  5. Check the box for “Key and Secret are ‘domain-level’ and can be reused for other tools in the same domain”.
  6. Check the box for “Show in featured tools list”.
  7. Enter the Tool Provider Key and Tool Provider Secret (provided by VoiceThread).
  8. Save changes.

Troubleshooting Tips

Error message: “Could not find Org for this launch.”

Make sure you have entered the Consumer Key correctly.

Error message: “The authentication failed; the signature on your request did not match the expected value” or “Unsupported Signature Method”

Check to make sure the Shared Secret is entered correctly.

If the Shared Secret is accurate, please make sure the clock on your Jenzabar server is accurate.

Error message: “Oh, buttons! We are unable to find [path]”

Make sure the URL is entered correctly.

Instructors can’t see student submission for grading

The student likely did not click the “Submit Assignment” button after completing his work. The student can simply go back into the assignment and click “Submit Assignment” at a later time. He will not need to re-do his work.

Instructors are seeing two different VoiceThread courses for each Jenzabar course

Jenzabar currently sends two different LTI context_ids per course, one from the Lessons module and one from the Coursework module. This results in two distinct VoiceThread courses, each of which can contain a different collection of VoiceThreads.  Jenzabar is looking into this issue to correct it.

You’re not automatically signed in to VoiceThread when you click on a VT link

Make sure your web browser accepts third-party cookies.

When you click on a VT link, you see a page titled “VoiceThread Account Verification”.

This means you already had a VoiceThread account under your email address, and the system is now trying to connect that existing account with your Jenzabar profile.  You’ll only need to complete this step once.  To proceed through this page:

  • Click on the link that says “Set it here” to set a verification password for your account.
  • Proceed through the steps to set a password.  This will involve receiving an email from VoiceThread.
  • Use that password you just set on the verification page.
