Using Desmos Test Mode in Kiosk Mode on Chromebooks
Kiosk Mode on Chromebooks can be used by administrators to lock devices to a single app, restricting students from navigating to other applications or webpages. Kiosk Mode is enabled differently depending on whether your devices are Managed Chromebooks or Unmanaged Chromebooks. (Check to see if your Chromebooks are managed.)
For more information on how to enable Kiosk Mode, check out Google's Use a Chromebook as a kiosk or Using Chromebooks for Online Student Assessments support resources.
Can Desmos Test Mode be used on devices other than Chromebooks?
Yes! Google Chrome Apps are accessible on OS X, Linux, and Windows desktop operating systems if the Google Chrome Browser is installed. If your students don't have access to Chromebooks, there are many applications and system settings that can be used on other devices to lock students to a specific app. Have any recommendations? We'd love to hear them - you can email us at calculator@desmos.com.
To access Desmos Test Mode on iOS devices, download the Desmos Test Mode iOS App from the App Store.
