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

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

No statistical significance
But sample size was too small due to poor
attendance at end of semester

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
