Conclusion
Motivation: Problem Statement
Constructivism
Learners are not blank slates that teachers write on
Learners need to actively construct their own
understanding and knowledge
But large lecture classes are not conducive for
active learning
Passive mode of oral dissemination
Lack of interactivity among students
Lack of interactivity with instructor
Motivation: Precedents
Face-to-Face Tutored Video Instruction (TVI),
Distributed TVI (Gibbons, Stanford)
Group review of pre-recorded lectures
Regular pauses for small-group discussion
Students using DTVI received grades 0.5 std dev
higher than non-TVI students (Smith et al. 1999)
Peer Instruction (Mazur, Harvard)
Lecture pauses for small-group discussion with
neighbors
Improvements in conceptual understanding and
problem-solving (Crouch and Mazur 2001)
Motivation: Small-Group,
Cooperative Learning
More than 375 research studies since 1898
(Johnson and Johnson 1989)
Cooperative group learning results in greater
Efforts to achieve
Higher-level reasoning
Transfer from original context to new situations
Generation of new ideas and solutions
Motivation:
Background Lecture Notes
(Hartley 1978, Kiewra et al. 1988)
Experiments on note-taking that compared
students annotating over:
1)
2)
3)
Complete lecture notes provided by instructor, vs.
Skeletal (i.e. partial) notes, vs.
No background notes
Results: students were found to achieve
maximum retention with skeletal notes
Livenotes Recap
Both a technology and educational practice
Large lecture classes
Small-group discussions in ongoing lecture
Cooperative note-taking:
Combines real-time note-taking with discussion
Augmented note-taking:
Skeletal slides for students to annotate over
Related Systems
No interaction between students
No real-time interaction between students, i.e.
sharing of notes takes place after lecture

Livenotes Evolution
2000: Implemented in Java, for WinCE Clios
Late 2000 to early 2003: 5 small-scale
deployments using Clios, laptops and
Tablet PCs
Spring 2003: Medium-scale experiment in
undergraduate class using Tablet PCs
Since 2003: Ported to Microsoft .NET

Hypotheses
Cooperative note-taking:
Shared whiteboard interface enhances
learning through cooperative note-taking and
discussion
Augmented note-taking:
Background slides enhances learning by
augmenting student note-taking
Experiment
Spring 2003 undergraduate
HCI class
21 volunteers, randomly
partitioned into
Cooperative note-takers
Individual note-takers
(control group)
4 weeks (7 lectures)
Preloaded skeletal PowerPoint slides
Previous Observation
From 5 previous deployments,
we learned that
Graduate students engaged
spontaneously in group
discussions
Undergraduates were not used
to discussing lecture material
with one another
For this experiment (with undergraduates), we held
short, live group discussions in the classroom
Data Collection
Short quizzes (4 lectures)
Survey questionnaires
First week of deployment (~38% response rate)
End of semester (~29%)
Qualitative interviews (3 users)
Transcripts of students’ notes (~1581 pages)
Quantitative Analysis
Unit of analysis: mark
Spatio-temporally
contiguous segment of
user input
E.g.: “This lecture is very
interesting”
Quantitative handcoding of ~1581 pages
Taxonomy of Marks
Note-taking:
someone taking notes on lecture
Commentary:
someone making a statement
Question:
someone soliciting a response
Answer:
response to a question, clarification
Reinforcement: contribution to an existing thread

Conclusion
Cooperative Note-Taking:
Richer Notes
Cooperative note-taking group engaged in more
than twice as much activity as individual note-taker
Cooperative Note-Taking:
Richer Notes
Almost one quarter of marks made by cooperative
note-takers were attributed to group interaction
Student Learning
Survey question: “How did Livenotes, if at all,
assist your learning in lecture?”
Early survey after 2 sessions with Livenotes:
75% of respondents self-reported affirmatively
Survey after semester (i.e. 7 lecture sessions):
83% of respondents self-reported affirmatively
Cooperative Note-Taking:
Taking Turns to Take Notes
66% of survey respondents agreed that
cooperative note-taking is more useful
“Someone else might note something that I
missed or hadn’t realized.”
“I liked how note-taking became a cooperative
effort … someone can take over if another user
is still inputing some notes, but the prof [had]
moved on already.”
Cooperative Note-Taking:
Paying Greater Attention
36% of students who self-reported learning
benefit explicitly attributed that to social
aspect of cooperative note-taking:
“Helped me to focus more in lecture. Often I
fall asleep/lose attention in lecture. Having
group members to respond to kept me better
on track.”
Cooperative Note-Taking:
Dual Conversations
Need to keep up with both lecture and ontablet conversation:
“It is helpful to be able to discuss questions.
However, this does take attention away from
the lecture if you are focusing on
answering/asking a question.”
Cooperative Note-Taking:
Decreasing Distraction
Is “running Livenotes during class distracting?”
(1 = extremely distracting,
5 = not distracting at all)
Survey after two lectures: 2.6 out of 5
Survey after deployment ended: 3.83 out of 5
From student notes, “playful” behavior were
observed to disappear almost completely after 2
lectures
Cooperative Note-Taking:
Unanswered Group Questions
Students did not have time to answer some
questions because they needed to keep up
with lecturer
Some questions were unanswered because
no group member knew the answer
Cooperative Note-Taking:
Interaction During Pauses
Group interaction during pauses in lecture accounted
for over half of group activity
Redeeming PowerPoint
Criticisms leveled at Microsoft PowerPoint
The Cognitive Style of PowerPoint (Edward Tufte)
Death by PowerPoint webpage
I Powerpoint (David Byrne, Talking Heads)
Too boring, passive, does not promote active
engagement with material
But students commented that augmented
note-taking is “like having a conversation with
the professor”
Augmented Note-Taking:
Observed Behaviors
Elaborated on bullets
Appended bullets to list
Concurred and disagreed with bullet
Noted gist of HCI principles
Noted advantage and disadvantage of HCI
technique
Answered questions in bullets
Augmented Note-Taking:
Elaborated on Bullets
Augmented Note-Taking:
Appended Bullets to List
Augmented Note-Taking:
Answered Questions in Bullet
Augmented Note-Taking:
Answered Questions in Bullet
Students responded to questions in bullets
even when when they were not cooperative
note-takers
Each group responded to 35% of the questions
Each question received a response from 36% of
the groups
Augmented Note-Taking:
Student Learning
Several high-quality notes in both individual and
cooperative note-taking groups resulted from
students “working off” bullets
Possibly due to bullets focusing student attention to
relevant portions of lecture
A larger proportion (55%) of students who selfreported learning benefit attributed it to augmented
note-taking, compared to cooperative note-taking.
Half of this sub-group attributed that to having slides
at hand to annotate over

Conclusion
Student-Instructor Interaction
To help instructor assess student
learning, we deployed feedback
feature in last two sessions
Students provide instructor with
real-time, anonymous lecture
feedback
Recently allowed students to alert
instructor that they have questions
Recommendation:
Background Slides as Scaffold
Bullets are a lightweight means for lecturer to
engage actively with students during class
Posing questions
Counter-intuitive bullets
Provocative statements
Direct student attention to critical parts of
lecture
E.g. prompts such as “Pros?” and “Cons?” with
blank spaces for students to fill in

Conclusion
Cooperative note-taking
Richer variety of notes, higher-order thinking
More than twice as much notes as individuals
Members took turns to take notes
Students kept awake to interact with group
Augmented note-taking
Observed dialogue with bullets
Reflected higher-order thinking
High-quality notes resulted from “working off”
bullets
