Constructivist theory of learning
3
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.

Improved Learning in a Large- Enrollment Physics Class[2]
before class: 3-4 pg reading, online reading quiz
in class: mix of peer instruction, instructor feedback, worksheets, demonstrations
before class: 3-4 pg reading
in class: PPT slides, 0–5 summative clicker questions (not peer instruction)

Improved Learning in a Large- Enrollment Physics Class[2]

Remember: Experimental section instructors LD and ES had no teaching experience but significant pedagogical content knowledge – knowledge about how people learn physics.

what methodology did they use?
how does the study contributes to our understanding about effective teaching methods?
what alternatives to lecture can we use to help students practice thinking and behaving in more expert-like ways?

Discussion (peer instruction)
Melt chocolate over low heat. Remove the chocolate from the heat. What will happen to the chocolate?
A)It will condense.

Chemistry learning outcomes
10
Students will be able to
name all 6 changes of state
translate back and forth between technical (“melt”) and plain English (“solid into liquid”)
Imagine…
misconception?

Typical Episode of Peer Instruction
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
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

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
16
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)

Clicker question
17
A ball is rolling around the inside of a circular track. The ball leaves the track at point P. Which path does the ball follow?
P
A
B
C
E
D
(adapted from Mazur)

Interactive Lecture Demos (ILD) [3]
18
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
19
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
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:
oevery student can contribute because everyone can wonder
oyou learn their pre-existing knowledge
oactivates concepts in their memories
Don’t let their enthusiasm slip away!

If you’re studying human behavior, let your students generate authentic data
For sensitive issues, clickers can be set to “anonymous”

Traditional classroom
27
1.Transfer: first exposure to material is in class, content is transmitted from instructor to student
2.Assimilate: learning occurs later when student struggles alone to complete homework, essay, project
1. learn easy stuff together
2. learn hard stuff alone

Flipped classroom
28
1.Transfer: student learns easy content at home: definitions, basis skills, simple examples.
2.Assimilate: students come to class prepared to tackle challenging concepts in class, with immediate feedback from peers, instructor
2. learn hard stuff together
1. learn easy stuff alone

Flipped classroom

1. learn easy stuff alone
2b. learn hard stuff together

Discussions
31
students share their understanding, opinions, ideas
students hear other students’ ideas, viewpoints
students practice communicating like experts
students get timely feedback from peers and instructor

Discussions: Implications for instructors
32
ensure students come to class prepared to contribute to the discussion
pre-readings that students want to complete (marks?)
orchestrate activity so EVERY student speaks (not just enthusiastic volunteers)
talking stick, whiffle balls, pass the duck, popsicle sticks, pass around an artefact
build in time/tasks for listening, getting feedback from peers and instructor

Showing video in class
34
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.
http://tinyurl.com/TCCdemo (Paul Hewitt video)

Opinion: Videos in class
35
In your opinion, the Paul Hewitt video
A)is engaging
B)is entertaining
C)is interactive
D)stimulates deep thinking

Showing video in class
36
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
37
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.

38
Veritasium (Derek Muller) http://www.youtube.com/watch?v=2KZb2_vcNTg
As you watch the video, notice how Derek talks to the people he interviews.

Is Lecture Dead?
39
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

To enhance students learning and retention, some instruction must be interactive and student-centered.
That’s how people learn.
