ClassTalk is an interactive classroom communication system developed by Better Education, Inc. . The system consists of a set of hand-held keypad entry calculators for the students, a central computer for the instructor, and a network in the lecture hall to connect it all together. Additional funding for the expansion of Classtalk has been provided by the U of C Provost's Program on Academic Technology Innovation, the U of C Women's Board, Research Corporation and the J and J Neubauer fund. Here is the schematic for the Classtalk system that is used in PS113. Setting things up.
