Student status is not connected (logged on to multiple devices)

Issue

In Class Tools in teacher mode, if a student is signed into multiple ChromeOS devices when the session begins, their status in the student list shows as Not connected with the message Student logged on to multiple devices.

Workaround

During Class Tools sessions, students should only be signed in on 1 ChromeOS device.

Students can’t open locked quizzes

Issue

For sessions where Class Tools is locked—Only allow Class Tools is turned on—students can't open quizzes that are in locked mode.

For details about locked mode for quizzes in Google Classroom, go to Use locked mode for quizzes.

Workaround

When sharing locked quizzes, before you start the session, remember to turn off Only allow Class Tools using Class Tools in teacher mode.

Unexpected YouTube URL behavior

Issue

Because of YouTube's unique navigation, standard URL restrictions are difficult to implement. So, in Class Tools, YouTube URLs are automatically restricted to This page only, and this navigation restriction cannot be modified.YouTube URL navigation restrictions vary depending on whether Only allow Class Tools is turned on or off for the session:

  • Only allow Class Tools is turned on— The navigation restriction behaves as expected, mirroring the behavior of This page only.
  • Only allow Class Tools is turned off—The navigation restriction behaves the same as All pages on this website.

Workaround

To ensure that Youtube navigation restrictions are applied as expected, in Class Tools teacher mode, ensure that Only allow Class Tools is turned on.

To properly restrict YouTube navigation, using Class Tools in teacher mode, ensure that Only allow Class Tools is turned on.
