What the best college teachers do[1]
More than anything else, the best teachers try to
create a natural critical learning environment:
natural because students encounter skills, habits,
attitudes, and information they are trying to learn
embedded in questions and tasks they find fascinating
– authentic tasks that arouse curiosity and become
intrinsically interesting, critical because students
learn to think critically, to reason from evidence, to
examine the quality of their reasoning using a variety
of intellectual standards, to make improvements while
thinking, and to ask probing and insightful questions
about the thinking of other people. 5

What is expertise? [2]
To develop competence in an area of inquiry, student
must
(a) have a deep foundation of factual knowledge
(b) understand facts and ideas in the context of a
conceptual framework, and
(c) organize knowledge in ways that facilitate retrieval
and application

Supporting expert-like thinking
CSULA 30 May 2014 11
Stop to let students
think and discuss
Pose a question for
students to think
about and discuss
Give choices to
direct the students’
conversations
2-min

peer
instruction

2-minute pause
Every 15-20 minutes of your lecture, stop talking
and invite the students to take 2 minutes to:
 review their notes
 consult with neighbors to fill in missing points
 check with neighbors if anything is confusing
 formulate a question(s) that will clear up
confusion or fill in a gap
When conversations dies down (wait longer than
2 minutes, if necessary), lead a brief class-wide
discussion to answer questions, resolve confusion.

2-minute pause (Pro version)
Pause to let students think and provide a
question in case they
 don’t have anything to talk about
 don’t know how to have an expert-like
conversion
 summarize material just covered
“What do you think would have happened if they ran
the experiment with adults instead of children?”
 motivate upcoming material
“How do you think this will change when we apply it in
3 dimensions instead of 2?”

Peer instruction
Pause to let students think, provide a question for
them to think about, and provide prompts so
they have the conversation you want them
to have.

In effective peer instruction
 students teach each other while
they may still hold or remember
their novice preconceptions
 students discuss the concepts
in their (novice) language
 each student finds out what s/he does(n’t) know
 the instructor finds out what the students
(don’t) know and reacts, building on their initial
understanding and preconceptions.
students learn
and practice
how to think,
communicate
like experts

The students have not
resolved concept X.
But they’re know X exists
and why X is interesting.

BEFORE DURING AFTER

Students have had
opportunities to
try, fail, receive feedback and
try again without facing a
summative evaluation. [1]

Effective peer instruction requires
1. identifying key concepts, misconceptions
2. creating multiple-choice questions that
require deeper thinking and learning
3. facilitating peer instruction episodes that
spark and support student discussion
4. leading a class-wide discussion to clarify
the concept, resolve the misconception
5. reflecting on the question: note curious
things you overheard, how they voted, etc. so
next year’s peer instruction will be better

What makes a good question?
clarity Students waste no effort trying to figure out
what’s being asked.
context Is this topic currently being covered in class?
learning
outcome
Does the question make students do the right
things to demonstrate they grasp the concept?
distractors What do the “wrong” answers tell you about
students’ thinking?
difficulty Is the question too easy? too hard?
stimulates
thoughtful
discussion
Will the question engage the students and
spark thoughtful discussions? Are there
openings for you to continue the discussion?
(Adapted from Stephanie Chasteen, CU Boulder)

Sample Questions
With a partner, look through the collection
of questions. Some are good, some are not.
Try to identify at least one characteristic
(clarity, context,…) that makes each
question good (or bad). Use the scorecard
to record your opinions.
