From FTEP, March 15th. Stephanie Chasteen, Science Teaching Fellow, Physics
Steven Pollock, President’s Teaching Scholar and Professor of Physics
Questioning is a central part of student assessment and quizzing, but it can also be a powerful learning tool. How does a teacher use questioning effectively? What is the right number of questions to ask? How do we avoid just giving students the answer? How do we avoid embarrassing our students, or confusing the class, if they give me the wrong answer? In this interactive workshop, we’ll explore research-based tips and ideas for questioning in a way that allow us to achieve the full benefit of questioning –student engagement and deep learning. We will focus on the use of “peer instruction” – the practice of requiring students to discuss their answers to challenging questions with one another. Peer instruction is facilitated by the use of “clickers”, but many benefits of the technique can be achieved even without the technology. We’ll discuss common challenges, share tips on getting students to productively argue and reason through the questions, and ways to encourage all students to speak up in response to questions.

7. Why question?
7
How many times have you given a lecture and found
that students hadn’t followed you?
Can you rely on students to ask questions if they
don’t understand something?
Can you rely on students to know if they don’t
understand something?
What are the benefits of questioning?

9. What is special about clicker questions?

Similar goals as other types of
questioning techniques
Multiple choice
Anonymous (to peers)
Every student has a voice – the
loud ones and the shy ones What does this tool help
Forced wait time us to do?
You can withhold the answer
until everyone has had time to
think (choose when to show the
histogram)
10. Clickers are a tool for questioning
10
But not a magic bullet!
Don’t equate the pedagogy with the technology.
So what IS the pedagogy?

Research shows that:
Students can better answer a similar question after
talking to their peers
Peer discussion + instructor explanation works
better than either one alone
Students like peer instruction
Peer instruction outperforms traditional lectures
on a common test

students. I know that there are at least ___ parts of
the technique that I’ll be changing:
A. None
B. One

D. Four or more
24. 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.
25. Some research on modifications

with Mazur’s Peer Instruction
30% report that they use Peer Instruction
50% of those use Peer Instruction in the way
described by developers
Often dropped are:
Student discussion Is this a problem?
Use of conceptual questions
Probably.

27. Some core philosophies of mine
Clicker questions are an integral part of my lecture
Students learn by
… teaching each other
… articulating their ideas
It’s important for me to
…. hear student ideas
… know what my students understand
I value and respect student ideas
I want students to
… know that I value student ideas
… feel safe sharing their ideas
28. Exercise #2 Challenges in the Classroom
28
You ask students a question, and ask them to discuss.
You then ask them to share their answers and
reasoning in a whole-class discussion
What could possibly go wrong? 5 mins
In groups of 3-5 brainstorm some of the challenges
you imagine in using this.
Brainstorm some solutions that are in line
with your core philosophies
Write on your handout and then scribe on board

you do to facilitate an effective wrap-up

•Establish culture of respect
•Consider whether to show the histogram immediately
• Ask multiple students to defend their answers
• Emphasize reasoning: Why are wrong answers wrong
and why right answer is right
39. Effects of increased wait time
39
Changes in student behavior:
More students respond
More students respond without being asked (unsolicited)
Student responses are longer
More alternative explanations are offered
All from a few
Student confidence increases more seconds!
There are more speculative responses
Students ask more questions
Other changes (on teacher!)
Quantity of questions decreased
Quality of questions increased
Expectations of slower students were revised
Teacher reactions to answers were more appropriate

HAVE PEOPLE SIT BY DISCIPLINE
How do you feel about asking students questions in class?How many times have you given a lecture and found that students hadn’t followed you?Can you rely on students to ask questions if they don’t understand something?Can you rely on students to know if they don’t understand something?So, what are the benefits of questioning?Why do you think people don’t question more?
We aren’t just trying to sell you on peer instruction because it seems like a good idea. There is lots of research on this. We’ll show a little later, but realize that lots of evidence points towards this being a more effective mode of instruction than lecture only.
Is this a problem? Unreasonable to expect adoption of any method wholesale without modification.Some modifications might increase effectiveness. But some components essential to student learning might be eliminated. Some dropped elements argued to be key to effectiveness by developers. Can’t assume faculty using PI is using as intended. Methods are related to or inspired by PI, but no longer recognizeable as PI, and so not been tested for effectiveness.
Questions threaten studentsI get no volunteers to answerStudents don’t talk to each otherAnswers take me off trackTakes too much time
What comes first? Learning goals.
During each section, ask people for examples of questions that they wrote that fall into this category. Give clicker booklet for responding.Point out the handout where each one is detailed more.

Usually one second. Trained to wait 3-5 seconds. Students tend to speak in bursts with 3-5 seconds between bursts: Wait time of 1 second interrupts these bursts.
