I am bringing my students to the computer lab for 3 weeks starting today. Usually they are self-motivated to use the computers to do the lab work. To be able to observe and assess how students are doing, I want to see ALL of their screens at the same time (every teachers dream).
The school has already installed VNC software on all of the student computers. This allows a teacher to observe one computer at a time, and even take control when the student is having difficulty with something.
For Mac’s, on OS X there is an AWESOME piece of software called Remote Desktop. ARD presents the teacher with a thumbnail view of each computer’s screen. When a student needs help, the teacher can switch to a full-size view of a single screen and then move the student’s pointer to assist.
I was able to find a windows program that can do some of this, called VNCon. It has it’s limitations, and hasn’t been updated since 2004.
I recommend checking out this software:
