Observations in classrooms using a network of handheld devices

Abstract This paper illustrates the educational implications of the design features of public anonymity and private accountability in a classroom network of handheld devices. The author draws from four years of observations of classes using two early network prototypes. Themes discussed are anonymity of data submission to the group, the ability for students to see their data displayed in the group space, the ability for the teacher to instantly assess how all students are doing at any time during a lesson, and that the ability of the network to let all students answer all questions may have an impact upon student engagement in the classroom. The paper goes on to highlight research done in the field of communications using synchronous electronic submission systems and relates this to the use of similar networks in the classroom.
