PRS at the University of Rochester
Frank L. H. Wolfs, Department of Physics and Astronomy
On this page I have compiled a number of usefull tools and links related to
the use of the Personal Response System (PRS) at the University of Rochester.
My first experience with the use of this system occured in Physics 121 (Spring
2004), an although I have used the PRS system in many different ways since
then, I certainly did not use every possible mode of operation.
In Summer 2007 the original PRS transmitters,
based on infrared technology, were replaced with transmitters that use radiofrequency
(rf) technology. The RF transmitters were used for the first time in Fall 2006
in Physics 141 and almost all of the problems associated with the use of the
infrared transmitters have been resolved with the introduction of the rf transmitters.
The biggest changes the instructor will see are:
- The students will see on their LCD display that their answers was accepted
(there is thus no longer a need to display the names of the students on the
screen in order to ensure they receive confirmation that their answer was
accepted by the computer.)
- The students will program their student ID number into their transmitter.
It is send as part of the answer when the students transmit their answer.
There is thus no need for the instructor to collect students IDs and match
these to the serial numbers of the transmitters.
The PRS units will be distributed by the bookstore, and the net cost to the
students is $ 10 (a $ 35 deposit is required at the time the students pick
up the units). To read the details of the agreement with the bookstore, click

manufacturer of the RF PRS system.
- Software: the software for the PRS system
is compatible with Windows and Mac OS X. The required software is installed
on the computers in the classrooms where we have installed PRS receivers
(Hoyt, Hubbel, Dewey, and B&L
106) but if you want to analyze the data collected while you use the PRS
system,
you should also install the software on your office computer.
- Software (Version 4.42.0010): the software for the PRS system
is compatible with Windows and Mac OS X. The required software is installed
on the computers in the classrooms where we have installed PRS receivers
(Hoyt, Hubbel, Dewey, and B&L 106) but if you want to analyze the data
collected while you use the PRS system, you should also install the software
on your office computer.
- The following links allow you to download installers for Windows
and Mac which you can use to install the software on your own computer
(note: these links are password protected). The current version of
the software is 4.42.0010:

- Typical use of the PRS system:
- When entering the class room, reboot the machine! This may not be required,
it works better if the PC is running with its default settings.
- Plug your USB drive into the computers USB slot (on the front).
- Start the PRS software (using the START menu on the PC)
- From the PRS menu select "Preferences" to define the location
of your data files.
- The box after "Data Directory" shows the location of the data files
that PRS is using. Click on the "Browse..." button after the "Data Directory"
text book to select the location of your data files on your USB drive.
- Press OK to accept the new location.
- If you have not defined a class yet, you should do so now. My Physics
141 classes are named as follows: phy141f06 is phy 141 taught in Fall
06. To define a new class you select the "Classes" tab in the main window
and click on the "New Class" button. A new window will open, allowing
you to define properties of the class (e.g. do you show a class roster,
the type of clickers being used, etc.) Once your class is defined, you
do not need to redefine it again in future sessions.
- You are now ready to start a new PRS session by clicking on the "New
Session" button. The pop-up window allows you to change the session settings.
- When you are done, select "End Session". Your session data
will now be written to the USB drive.
