Show the Teacher's Screen to Students in LanSchool Classic
Overview
LanSchool Classic allows teachers to share or broadcast their computer screen to one or more student computers. This feature is useful for demonstrating lessons, presenting instructional materials, walking students through assignments, and displaying information directly on student screens.
Teachers can share their screen in two modes:
Full Screen Mode: Displays the teacher's screen across the entire student screen. Student keyboards and mice/trackpads are locked while the screen is being shared.
Windowed Mode: Displays the teacher's screen in a resizable window, allowing students to continue working on their computers while watching the demonstration.
Teachers can also draw on their screen while sharing to highlight important information.

Troubleshooting Show Teacher Screen
Why can't I show my screen to more than 32 students?
LanSchool Classic supports two communication methods for the Show Teacher and Show Student features: TCP and UDP.
The TCP Show Teacher/Student function has a maximum limit of 32 students.
If you are unable to share your screen with more than 32 students, check the Teacher Console preferences:
Open the Administer menu.
Select Preferences.
Open the Teacher tab.
Locate the setting Use TCP protocol for better performance, especially for mobile devices.
Review whether this setting is enabled.
The TCP protocol has a 32-student limit. The UDP communication method should be used when sharing with larger groups.
Why is Show Teacher Screen not working on macOS?
If the teacher computer is running macOS and screen sharing is not working, macOS may be preventing LanSchool Classic from accessing the teacher's screen.
To enable screen-sharing permissions:
Open System Settings on the teacher's Mac.
Select Privacy & Security.
Select Screen & System Audio Recording.
Locate Teacher in the application list.
Toggle the permission on.
After enabling the permission, try sharing the teacher's screen again.
