Clicker Question 1
 Which of the following best describes your
experience with classroom response systems
(clickers)?
 A: I use clickers extensively in my courses.
 B: I use clickers sparingly in my courses.
 C: I am familiar with clickers but have not yet used
them in my courses.
 D: I’m completely new to clickers and their use in the
classroom.

Introduction
My experience with clickers
Effective use of clickers in the classroom
Administrative overheads

4
Experience
First experience in graduate school (Ireland ~
2008) but no personal experience.
Extensive use during my postdoc at the
University of Washington
Use was motivated by recent physics
education research, in addition to personal
preference.

Physics Education
Research
“Interactive-engagement versus traditional
methods: A six-thousand student survey of
mechanics test data for introductory physics
courses,” R.R. Hake, Am. J. Phys. 66, 64-74
(1998).
Significant findings included that courses that
used interactive-engagement methods had
much larger gains that courses using
traditional methods

Clicker Question Example
 Two gliders, A and B, collide on a level, frictionless track, as shown
below. The mass of glider A is less than that of glider B (i.e.,
mA < mB). The final speed of glider A is greater than that of
glider B (i.e., vAf > vBf).

After collision

vBi = 0

 Is the magnitude of the final momentum of glider A, |pAf|,
greater than, less than, or equal to that of glider B, |pBf|?
 A: Greater than
B: Less than
C: Equal to
D: Not sure

Effective Use
Clicker questions should ideally foster
discussion, and challenge student ideas.
Effective questions often address conceptual
difficulties.
Other questions can be useful in judging the
effectiveness of the lecture, by gauging the
level at which students understand the
material.

Administrative
Considerations
11
Should I award course credit for clicker
responses? If yes, how much?
Should I award credit for correct responses?
Shared responsibility between instructor and
student.
