What is a Classroom Response System (CRS)?
Classroom Response Systems were invented in the late 1980’s as a way to increase student participation in class. A CRS is a small network (radio frequency, infrared, or wired) for an individual classroom. It is comprised of three, sometimes four elements: A computer with a projection device, student transmitter units, a receiver unit, and sometimes an instructor unit. The computer runs a software package that processes and displays the student feedback as it comes into the receiver. Students use this system to give immediate feedback to questions posed by the instructor. Classroom Response Systems use grew slowly through the early 1990s. However, the widespread use of presentation software and projectors in classrooms in the late 1990’s created an environment for their increased use. Today’s Classroom Response Systems offer the advantages of Radio Frequency (RF) technology, such as faster transmission of answers, two-way communication between the instructor receiver and student remote,
