You will use your PRS transmitter to answer Multiple Choice questions during the lecture period. Your answers will be graded, and your PRS grade will count 5% of your overall class grade. For the first two weeks, PRS questions will be considered practice questions, as you learn to use your PRS transmitters. Beginning Wed. Sept. 6, PRS questions will be graded.

To the left is an image of a PRS transmitter ready for use. On the back you will find a nine-digit number (this is not a number associated with the store's bar code; if you have a store bar-code sticker on the back of your clicker, pull it off). This is your PRS ID NUMBER. You will need this number in order to register your transmitter. You should not buy an older transmitter that has only a five-digit number on the back; these may not work properly. What if my transmitter has only 6 digits on the back (like in the photo)?

When using your transmitter, first be sure that it is turned on. To submit your answer, point it at one of the PRS receivers scattered about the room. An image of a receiver is shown to the right. IMPORTANT: IT IS YOUR RESPONSIBILITY TO MAKE SURE THAT YOUR TRANSMITTER IS IN WORKING ORDER AND THAT YOUR SUBMITTED ANSWERS ARE RECEIVED. Watch for your PRS ID number to appear on the computer screen at the front of the classroom; this will indicate that your submission has been received (tips). You may answer any question twice within the given time limit (once is all that is necessary). You may change your answer the second time. If you submit two answers, only the second answer will be graded. The H (high) and L (low) buttons can be used to indicate your confidence in your answer; this information will not be used in any way this year. You can find out more about how PRS works here.

How To Register Your Transmitter

Besides your PRS ID NUMBER, the other number that you need in order to register your PRS is your POSTING ID number. This number is comprised of the last four digits of your Affiliate ID number, followed by a hyphen, followed by the last three digits of your ASU ID number. The Affiliate ID number is the ten-digit number on your Sun Card; the ASU ID number is the nine-digit number.

Finally, you need to know the letter identification of your recitation section. Get that from the following table:

For example, if Joe Student is a 121 student in the W 3:40 recitation meeting in PSF-366, his section letter is F.

To register your PRS, send an email to me at gary.adams@asu.edu. The subject line MUST be

PRS registration for PHY 121 MWF

The body of the email should contain only one line, in EXACTLY the format presented below for Joe Student. If the format is not correct, your PRS answers will never be credited to you. (NOTE: If you use an html emailer, make sure to send your email as text only, not html.) Assuming that Joe Student's PRS transmitter has the ID number 000153471, this would be Joe Student's email:

000153471 1234-567 F Student Joe
