…in the winter of 1813 & '14 … I attended a mathematical school kept in Boston…On entering his room, we were struck at the appearance of an ample Black Board suspended on the wall, with lumps of chalk on a ledge below, and cloths hanging at either side. I had never heard of such a thing before. [Samuel J. May, 1855]
Goal: Improve interaction in the classroom
Provide flexible mechanism for delivery presentation
Support interaction between student and instructor devices around presentation materials
Classroom Presenter
Integration of slides and digital ink using Tablet PC
Key ideas: Ink overlay on images Distributed application
Many other systems also support ink and slides
Ink Usage In Exposition
Initial motivation Increase flexibility of slide based
presentation Adjust presentation in response to the
audience
When is ink important? Ink is NOT always important for slide
based presentation Classroom presentation is different from
professional / conference / meeting presentation
Ink is important when: The instructor interacts with the audience Displayed material is the focus of attention
Examples of Ink Usage
Slides from selected university courses
Demonstrate range of use in class
Attentional ink and incidental writing
Writing with mathematical content
Stepping through example
Diagram augmentation
Diagram AugmentationInstructor view
Rich Diagrams
Fill-in simulation
Process Trace
Collective Brainstorming
Collective BrainstormInstructor View
Ink based demonstrationQuikwrite [Perlin, NYU]
Instructor notes Different layers available in different views
Base, Instructor, Student, Shared PPT Plug in allows creation of notes
Presenter Configurations Single Machine (1 Tablet PC)
Direct projection from instructor view Single view, tethered
Projection of second monitor from tablet Multiple views, but tethered
Multiple Machine (1 Tablet PC + Other devices)
Wireless connection to display view Multiple views, untethered Distance learning and integration with student devices
Presenter Features Tablet PC Ink Multiple Colors Highlighter Stroke Erase Page Erase Undo
Slide Minimize Whiteboard Multiple Decks Filmstrip
Navigation Slide previews Ink Export
Form factor issues Carrying the tablet while lecturing
Some like to carry the tablet, others don’t Weight and size are issues
Eye gaze is a problem Vision angle and reflection can be
problems for instructor Tablet button fumbles
“And I see Windows is shutting down” “Here is the Australian view”

Student Submissions with Classroom Presenter
Ruth Anderson
Student Submissions
Students annotate slide Submit ink to instructor Instructor selectively displays
student responses to the class
Motivation: to promote student involvement with lecture
Trace the path of Lewis and Clark from Saint Louis to Astoria
Find the roots of x2 + 3x + 4
Show that increasing supply of housing lowers equilibrium price

Student Submissions Supports Active Learning where
students with Tablet PCs can complete an activity submit anonymously student work
reviewed/discussed/augmented selectively by instructor
electronic copy of student work available after class
use rich backgrounds and color
Preliminary experiences
Problem solving in parallel Multiple solutions and misconceptions
Allow independent work Spontaneous activities with
structure Build on instructor designs or
scaffolding
Uncover Common Errors
Compare Different Approaches
Use Background Slide & Color
Solve Different Problems in Parallel
Problem Solving
Assessment of Student Learning

Structured Interaction Presentations
Modern Pedagogy vs. Modern Practice
active learning
participatory
interactive
student-directed
lecture
instructor-dominated
passive
disconnected
Goals of Structured Interaction Presentation System (SIP)
Keep best of PPT & augment interaction 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.
