Highlights
   What are clickers? What can you do with them?
   Who can use them?
   When are they available to you and your students?

   Where do you get the equipment?
   How do you get started?

Clickers enable you to do student-centered learning. Let’s
start with a “student”-centered activity, rather than with
me lecturing. This is what clickers are about.
Some examples of how
clickers can be used
in classes
By show of hands…
Who believes:
“Not enough students answer
questions that I ask during class.”
Not enough students answer
questions that I ask during class.

PRE-TEST & POST-TEST STUDENTS TO
ASSESS LEARNING: A light year is a measure of

Dave: Timed question!
Checking current understanding
during class
A miniature astronomy lecture
   The universe is 13.7 billion years old.
   A light year is ____________________________.

As seen here, you can also visually compare to
questions, or, in this case, pre- and post-lecture
Purple = previous. Blue = current.
Think-Pair-Share
   Ask the question
   If results are between 50-90% correct,
consult with your neighbor and vote again
   Usually results improve noticeably
   Students understand and remember concept
better
   Takes only 1 minute or less
MORE CONCEPTUAL UNDERSTANDING:
It is possible for astronomers to detect an object 15 billion
light years away from Earth.

Old version

What are clickers?
   Clickers send signals using Radio
frequency (RF) light to a computer.
Computer processes the data.
 Radio light doesn’t require line-of-sight
 Receiver is small and portable.

   NEW clickers have a screen for direct
feedback to student; allows for clicker-
tests! (They use AAA batteries.)

New version
What can you do with clickers?
   Taking attendance (automatically calculated if any question is asked)
   Classroom demographics – who are your students?
   Ice-breakers
   Gathering feedback about class or getting opinions
   like/dislike activity, useful/useless, etc.
   Discussion starters
   Quick assessment of recently covered material
 Ask about facts or conceptual understanding.
 No question is too easy to ask students. You’ll be amazed.

 Build their confidence or shake yours!

   Pre- and post-instruction questions. (Did they learn?)
Uses, continued
   Data gathering – very useful for SLOs, Accreditation
   Cooperative learning: Think-pair-share
   Quizzes
   End of class summary
   Beginning of class review
   Determine if students did reading/homework
   Full-length tests
   Ranking choices
   On-the-fly questions to suit whatever comes to mind
during class.
   Fastest responses
Information gathered by clicker
   Which clickers responded to the question
   What answer each clicker gave to each question
   If multiple answers given, order is saved
   Can be used for entering multi-digit numbers/decimals or
ranking.
   How long it took each clicker (student) to answer
   When a question is re-polled, both answers sets
are saved
   Results are easily exported to Excel
Who can use clickers?
   Anybody with basic knowledge of computers
   Knowledge of PowerPoint helpful, but not required.
   New version of TurningPoint software (called
“TurningPoint Anywhere”) can be used outside of
PowerPoint. Also available for Macs.
 Data stored.
 Screenshots saved.
When are they available to you and
   Right now!
   If you’re interested in using them in your classes
or even just trying them out, stay tuned and let’s
talk after this presentation.
   Hoping to purchase classroom sets of clickers
   Having students buy the clickers doesn’t work very
well for teacher or student. Also, can’t sell back.
Why you should use clickers…
Effects clickers have had on my classes
   Physics 2A: summer 2007/2006 vs.                                summer 2003
   Success: 29/35 = 83%; 31/44 = 70%                           28/49 = 57%
   Retention: 31/35 = 89%; 42/44 = 95%                         30/49 = 61%
   Success (percent who passed) in Astr 25 went up by 9%.
   Success in Astronomy 20 increased 15%
   Data were compiled from my spreadsheets. Therefore numbers aren’t exact.
   I estimate attendance is 60% w/o clickers & 75% with,
Note: clicker participation counts little towards grades.
   Research at 4-year schools shows attendance at 85%.
   Similar research shows students read the text more, are more
interested in the course, and have a more positive attitude
towards the course.
   When I don’t use clickers during class, I get complaints!
Students like clickers and learn from using them.
More reasons why you should consider
using clickers in your classes
   Interactive
   Student-centered, minds-on
   Just-in-time teaching is available with pre-tests (clicker? Do you know?)
   Immediate feedback – to you AND your students
   Fun
   Gets everyone actively (not passively) involved (anonymous)
   Especially shy students!
   Early and frequent assessment
   Diagnose and fix bad lectures/activities
   Catch poor students quickly, start troubleshooting early
   Scantron forms are obsolete. Clickers provide more data, helps you
write better tests. Also faster grading.
   Attendance increases (in my class, research)
   Retention increases (in my class, research)
   Success increases (in my class, according to lots of research)
   We can use clickers to gather data for SLOs, as needed
Clicker capabilities
   The following slides show some other things
you can do with clickers.
MULTI-ANSWER: Which of the following are NOT types
of electromagnetic radiation? Select all that apply.
1.   Gamma rays
2.   X-rays
3.   Infrared
4.   Ultraviolet
5.   Ultrasound
6.   Sound waves
7.   Microwaves
Improve in-class demonstrations
   Explain the demo set-up
   Have students predict the outcome
   Do the demonstration
   Specifically ask students “Was your prediction
correct?” (De-isolate, recognize intuition can be
wrong)
I will drop a pen and a crumpled piece of
paper. Which will hit the ground first?
2    1.     The pen will hit the ground first.
2    2.     They will hit the ground at the same time.
1    3.     The paper will hit the ground first.
I will now perform the demonstration
Quizzes & Tests
   These clickers can handle tests & quizzes
   The software is different, not as user-friendly (yet)
   Requires some student training of the clickers, so I
won’t demonstrate that now.
Where do you get the equipment?
   Clickers – cost \$45 + Shipping & Handling. Need
classroom sets. Class set of 45 costs ~\$2500. 40 = \$2200.
   Receiver – needed to get the signals from the clickers. You
get this from me.
   Natural Science received I-grant from ECC Foundation to
purchase receivers for entire division. We decided to share.
   I have 31 receivers to distribute.
   Have your dean ask me to send __(how many?)___ receivers to
your division office. [Accounting]
   Software to interpret the signals.
   I will be setting up a local web page with more info soon.
How do I get started?
   Get the receiver (and purchase a clicker)
   Staff Development has a set to use in their training room.
   Train yourself for the software
 Self-exploration
 Web-based demonstrations

 Read the manual

 Staff Development classes coming soon

   Start small in your classes

   There are a LOT of things you can do with clickers in
   Method of student-centered learning
   They dramatically increase learning
   Particularly well-suited for lecture classes
   Now available campus-wide
