Prediction
Alternatives to Lecture 4
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.
Key Finding 1
Alternatives to Lecture 5
Students come to the classroom with preconceptions about how the world works. If their initial understanding is not engaged, they may fail to grasp the new concepts and information that are taught, or they may learn them for the purposes of a test but revert to their preconceptions outside of the classroom.
(How People Learn [1], p. 14)
Instructors must
draw out students’
pre-existing
understandings.
Instruction must be
student-centered.
Key Finding 2
Alternatives to Lecture 6
To develop competence in an area, students 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.
(How People Learn [1], p. 16)
These are
characteristics of
expertize
Instructors need to give
students opportunities
to be more expert-like.
Key Finding 3
Alternatives to Lecture 7
A “metacognitive” approach to instruction can help students learn to take control of their own learning by defining learning goals and monitoring their progress in achieving them.
(How People Learn [1], p. 18)
Instructors need to
provide opportunities for
students to practice being
metacognitive
Metacognition: that
voice in your head
that checks if you
understand
Constructivist theory of learning
Alternatives to Lecture 8
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 “try, fail, receive feedback and try again,
before facing a summative evaluation.” [2]

Discussion (peer instruction)
Melt chocolate over low heat. Remove the chocolate from
the heat. What will happen to the chocolate?
A) It will condense.
B) It will evaporate.
C) It will freeze.
Alternatives to Lecture 11
Typical Episode of Peer Instruction
Alternatives to Lecture 12
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 13
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.

Upcoming Weekly Workshops at the CTD:
To register, look for the
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.

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)

Interactive Lecture Demos (ILD) [3]
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

Start teaching before the bell rings
Alternatives to Lecture 22
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?” [8]
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!

There are times when a video is the perfect resource.
Archimedes’ Principle
In today’s Physics class, we’re
going to study buoyancy and
Archimedes’ Principle.

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
