Screen Lock allows the teacher to freeze student screens and display a custom message. The button is enabled when a class session is active.
Screen Lock can be applied to an entire class, or individual students.
To apply Screen Lock to individual students, choose the students from the list prior to clicking the Screen Lock button.
To apply Screen Lock to an entire class, click the Screen Lock button first, then answer "Yes" to the prompt "Do you want to apply Screen lock to all devices in the class?"
Enter a custom message to appear on the student screens. The message will be remembered and used as the default for the next screen lock. After entering the message, click the Screen lock button.
When screen lock is active, a lock icon will appear in the top bar of tab view or the bottom right corner of the screen image in thumbnail view.
To end screen lock for one or more students, choose an individual student or the entire class, then use the Release button.
