Pedagogy of Active Learning
• Encourage “connected” learning– Constructivism [Bruner]– Social learning [Lave]
• Recapture flagging attention– Attention studies [Stuart & Rutherford]– Heart rate/memory [Bligh]– Skin conductivity [Picard]
• Address varied learning styles – Index of Learning Styles [Felder & Silverman]– Bloom’s taxonomy
![Page 4: Not Listening: Interaction, Technology, and Education Steven A. Wolfman Computer Science & Engineering University of Washington](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d4e5503460f94a2db94/html5/thumbnails/4.jpg)

Motivating Problem: Large Classes
“Class Sizes & Course Section: smaller is better; large is survivable”– McKeachie’s Teaching Tips
![Page 6: Not Listening: Interaction, Technology, and Education Steven A. Wolfman Computer Science & Engineering University of Washington](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d4e5503460f94a2db94/html5/thumbnails/6.jpg)

Turn the Question Around…
How can a large class be an advantage?– “Madness of the Crowd”– Diversity– Amortized resources– Large N: human simulations

Kinesthetic Learning Activities (KLAs)
Active learning exercises that physically engage students in the
learning process
http://www.cs.washington.edu/research/edtech/KLA/, [SIGCSE 2004]
![Page 9: Not Listening: Interaction, Technology, and Education Steven A. Wolfman Computer Science & Engineering University of Washington](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d4e5503460f94a2db94/html5/thumbnails/9.jpg)

t
Why KLAs?
• Combat physical disengagement (e.g., [Bligh], [Picard])
• Tap different learning styles – active, sensing, inductive [Felder & Silverman]– kinesthetic [Fleming]– sensorimotor learning [Piaget]
• Construct knowledge by analogy

Motivating Problem:Feedback Lag
Evidence:– Pilot survey/focus group responses– Personal experience– Lagged questions in video archives
A student hesitates to pose a question until the instructor finishes a point. When the instructor moves on, the student’s question seems out of place and is left unasked.
[CSCL 2003]
![Page 13: Not Listening: Interaction, Technology, and Education Steven A. Wolfman Computer Science & Engineering University of Washington](https://reader030.vdocuments.us/reader030/viewer/2022032800/56649d4e5503460f94a2db94/html5/thumbnails/13.jpg)

CFS Evaluation
Intro. programming course, summer 2002:– 150 students total– 12 with laptops– 9 week course, 3 weeks with CFS
Data: observations, surveys, focus groups, interview w/instructor, logs

Retrospective Feedback
Students’ response:– 0.35 retrospective feedback/person/class– CFS helped 3 who cited feedback lag– 2 others reported feedback lag w/CFS
Instructor’s response:– Retro. feedback is important; often responded– Retro. feedback upset pacing

Goals of Structured Interaction Presentation System (SIP)
• Keep the good of PPT, counteract the evil
• Integrate into the “mediating” slides
• Support intuitive and flexible design
• Facilitate interaction in class
• Enable new kinds of interaction
Make design and execution of interactive presentations as easy as for passive ones.
