Our classroom is set up with 7 student desktop computers and 4 wireless laptops the work off an Airport. The computers are located at each student group - facing the desks. One or two students leave each table group to work at the laptops in pairs. More pictures of students working at computers.
Students work cooperatively, passing the keyboard to give each student in their group equal access.
If students need to work individually, the computer is rotated 90 degrees and the student works independently away from the group.
