About these slides
We have created a variety of workshops on clickers and Peer Instruction for faculty and K12 teachers. These slides represent the presentations and activities that we have produced through this work. You are free to use this material with proper attribution (see previous slide).
Not all slides or activities were used in every workshop.
Activities are designated with a peach background to the slide

Introducing Me5
Applying scientific principles to improve science education – What are students learning, and which instructional approaches improve learning?

“Clickers” are really just a focal point
We aim to help instructors:Use student-centered, interactive teaching
techniquesBy the use of a tool (clickers) which makes a
transition to that pedagogy easier
Our talks are “how people learn” talks in disguise.

The typical pattern of professional development for faculty…
(we) Tell them how to do it (they) Try it (they) Fail or fade (we) Repeat (louder!)
In physics, half of faculty only use Peer Instruction for a single semester
What’s missing? We need to help faculty anticipate challenges and difficulties with
implementing peer instruction. Lose the rose-colored glasses! We also need to provide less prescriptive “do this, don’t do that”
recommendations, which are hard to remember, and instead provide a pedagogical strategy which will naturally lead to those “best practices”
These workshop materials are intended to help overcome some of the challenges to sustainable improvements in teaching, as based on the research on instructional change.

How we try to accomplish goals:
Give a clear introduction to peer instruction. What does it really look like?
Give experience in peer instruction. How does it feel as a student? As an instructor?
Provide disciplinary experience. Give examples from multiple disciplines; have instructors sit next to others who teach in their subject area
Why does it work? The research.Respect their experience. Answer their
questions/challenges, rather than being gung-ho salesman.Provide opportunity for practice and feedback. Especially
in writing questions and facilitation.Practice what we preach. Do all this in a student-centered,
interactive environment. Don’t lecture about how not to lecture.

Research about peer instruction
Peer instruction helps students learn
Research shows that:Students can better answer a similar question
after talking to their peersPeer discussion + instructor explanation of
question works better than either one aloneStudents like peer instructionPeer instruction classes outperform
traditional lectures on a common test

Clicker Question
Honestly, I think that I’m most likely to modify this technique of peer instruction to suit me and my students. I know that there are at least ___ parts of the technique that I’ll be changing:
A. NoneB. OneC. Two-threeD. Four or more
Is there a problem with modifications?
I won’t tell you how to teach. You’re smart & you care about instruction.
Be strategic about modifications. Know the research.
Some research on modifications
63.5% of faculty (in physics) say they are familiar with Peer Instruction
30% report that they use Peer Instruction50% of those use Peer Instruction in the way
described by developersOften dropped are:
Student discussion Use of conceptual questions Whole-class voting
Dancy & Henderson, Pedagogical practices and instructional change of faculty, Am. J. Phys., 78(10), Oct 2010.Web survey of 722 physics faculty at various institutions, initial sample of 2000.
Is this a problem?Probably.

Why do you think this happens?(A) Students are getting answers from the ‘smart’ kids (B) They’re learning from their discussions (C) They just needed more time to think about it
The hypothesis: If students learn from peer discussion, they should show better performance on a similar question. Ask a second, similar question without any instructor input: Q2

Then explain answers to Q1 and Q2
Students answer Q1 individually.
1)
Students talk to neighbors and answer Q1 again (Q1AD = Q1“After
Discussion”).
2)
Students answer Q2 individually . Q2 tests same concept as Q1.

Can students answer difficult questions correctly after discussion?

Q2
Very few students knew correct answer to Q1, but after discussion, many more answer correctly: students are constructing their own knowledge
