Seamless Interaction
In a classroom setting, students work together better if they are focused
on a common workspace. Yet this is difficult to achieve in computer-based
education. Children working on separate computers, even if they are side
by side, do not perform as well as they would if they were huddled around
a single machine [Inkpen 97]. Indeed, researchers have found that when
students are assigned to individual computers, they will spontaneously
cluster around machines in pairs and trios [Watson 91, Strommen 93].
