Constructivist theory of learning
Alternatives to Lecture 5
Students need to construct their own understanding of the
concepts, where
each student assimilates new material into his/her own
framework of initial understanding and preconception
each student confronts his/her (mis)understanding of
the concepts
A traditional, one-way lecture doesn’t give students an
opportunity to construct their own knowledge, practice a
skill, or receive timely, formative feedback.
Active learning increases student performance
in science, engineering and mathematics[1]
Alternatives to Lecture 6
Massive meta-analysis of 225 research studies that explored
the impact of active learning:
Active learning engages students in the process of learning
through activities and/or discussions in class, as opposed to
passively listening to an expert. It emphasizes higher-order
thinking and often involves group work.
(Freeman et al., pp 8413-8414)

Typical Episode of Peer Instruction
Alternatives to Lecture 11
1. Instructor poses a conceptually-challenging
multiple-choice question.
2. Students think about question on their own and vote
using clickers, colored ABCD cards, smartphones,…
3. The instructor asks students to turn to their neighbors
and “convince them you’re right.”
4. After that “peer instruction”, students may vote again.
5. The instructor leads a class-wide discussion concluding
with why the right answer(s) is right and the wrong
answers are wrong.
In effective peer instruction
Alternatives to Lecture 12
students teach each other while
they may still hold or remember
their novice preconceptions
students discuss the concepts in their
own (novice) language
each student finds out what s/he does(n’t) know the
instructor finds out what the students know (and don’t
know) and reacts, building on their initial
understanding and preconceptions.
students practice
how to think,
communicate
like experts

Teaching and Learning Weekly Workshops
at ctd.ucsd.edu
Nov 19 Peer Instruction 1: Writing Good Peer Instruction (“Clicker”)
Questions A good episode of peer instruction requires a good question. In
this session, we’ll see a variety of questions and contrast good vs bad
questions, that you can adapt to your discipline
Nov 26 Peer Instruction 2: Best Practices for Running Peer Instruction
with Clickers In this session, we’ll discuss best practices for
choreographing an episode of peer instruction in your class including how to
pose the question, when to open and close the poll, how many votes, and
how to get the most out of the class-wide discussion.

Conclusion:
Failure rates in
active classes drop
significantly.

Bigger Conclusion:
Under-represented
minorities and
women make up a
disproportionate
number of students who fail STEM classes. Fewer
failures means enhanced success for URM and women.

In-class demonstrations
Alternatives to Lecture 17
1. Instructor (meticulously) sets up the equipment, flicks
a switch, “Taa-daaah!
2. Students
don’t know where to look
don’t know when to look, miss “the moment”
don’t recognize the significance of the event
amongst too many distractions
To engage students and focus their attention on the key
event, get students to make a prediction (using
clickers, for example)
Prediction
Alternatives to Lecture 18
Ice cubes are floating in a glass of water
that is filled to the brim.
As the ice cubes melt, what happens to
the water level?
A) it stays the same
B) it rises and spills water over the brim
C) it falls to a level below the brim.
Interactive Lecture Demos (ILD) [3,4]
Alternatives to Lecture 19
By making a prediction, each student
cares about the outcome (“Did I get it right?”)
knows when to look (can anticipate phenomenon)
knows where to look (sees phenomenon occur)
gets immediate feedback about his/her understanding
of the concept
is prepared for your explanation
Artefacts
Alternatives to Lecture 20
Bring things – real things – to class/section.
Don’t just tell students what
they’re looking at. Ask them
what they notice, what they
think it is.
“Ask me a question an
archaeologist would ask.”

Start teaching before the bell rings
Alternatives to Lecture 23
Students arrive, ready to engage with you, your content:
Project a picture related to today’s lesson
Add prompts:
“What do you notice? What do you wonder?” [5]
Spend first few minutes leading a discussion:
o every student can contribute because everyone can wonder
o you learn their pre-existing knowledge
o activates concepts in their memories
Don’t let their enthusiasm slip away!

In your opinion, the Paul Hewitt video
A) is engaging
B) is entertaining
C) is interactive
D) stimulates deep thinking
Showing video in class
Alternatives to Lecture 27
The students do not
select the video
check it contains key events
anticipate key events
recognize key events
interpret key events
relate key events to
class concepts
instructor does this
before class
instructor does this unconsciously,
the “curse” of expertise
This is what you want to do in class!
anticipate and recognize are
necessary for rich discussion/analysis.
Videos: implications for instructors
Alternatives to Lecture 28
Coach the students how to watch the video like an
expert:
As you watch this video, try to…
watch for when the A starts to B.
count how often the C does D.
watch the needles on the scales as water drains.
Don’t “give away” the key event (Notice the buoyant force
is equal to the weight of the fluid displaced.) That’s what
the follow-up discussion is for: help the students get
prepared for that discussion.
Is Lecture Dead?
Alternatives to Lecture 29
No! There is still a time and place for lecture. You can
lecture (for 10-15 minutes) when the students are
prepared to learn:
the alt-to-lecture activities have activated the concepts
in their memories
they’ve tried, failed, received feedback, tried again and
are waiting for confirmation
they’re prepared to intellectually appreciate the
expertise you’re about to share with them

retention, some instruction must
be interactive and student-centered.
That’s how people learn.
Alternatives to Lecture 31
If the experiments analyzed here had been conducted as
randomized controlled trials of medical interventions, they may
have been stopped for benefit—meaning that enrolling patients in
the control condition might be discontinued because the treatment
being tested was clearly more beneficial.
(Freeman et al., pp 8413)
Finally, there is a strong ethical component. There is a growing
body of evidence showing that active learning differentially
benefits students of color and/or students from disadvantaged
backgrounds and/or women in male-dominated fields. It’s not a
stretch to claim that lecturing actively discriminates against
underrepresented students.”
(S. Freeman, in [6])
