"Bring your own laptop unless you want to follow the lecture": alternative communication in the classroom

The introduction of laptops and wireless networks in classrooms has increased the possibilities for student-teacher interaction. Here we explore the premises for this interaction by studying the use of ActiveClass, a system that enables students to ask questions electronically and anonymously in-class. The study emphasizes how the diverse prerequisites for teaching interaction separates students even more in the classroom. We then suggest a differentiated approach to the introduction of interactive technologies in the class room.
