Mediating Artifact An external object or structure which participates in cognition by shaping or supporting thought. Saljo: the significance of new technologies does not lie in their enhancing learning in a linear sense… the important point … is that they … transform basic features of how people communicate knowledge and skills … and how information is organised. In this sense, new media may imply that learning will become different. Steve Wolfman Technology, Education, and Interaction

Large class challenges • Maintaining attention • Communication/Feedback • Spontaneous discussion • Management of class activities Is PowerPoint evil? Steve Wolfman Technology, Education, and Interaction
Good Organization Preparation Sharing Easier execution … Evil Passivity Simplification of ideas [Tufte] Inflexibility … PowerPoint Good and Evil Preliminary studies indicated instructors needed: flexibility and contextual writing PETTT studies suggest students like: organization and preparation. Steve Wolfman Technology, Education, and Interaction
Slides as Mediating Artifact • In the classroom: • facilitate communication • structure discussion • Outside the classroom: • used as memory aid • used as study guide • Across terms • reify course knowledge Persistent context for communication! Steve Wolfman Technology, Education, and Interaction
Classroom Presenter Goals REFER TO LODGE • Maintain strengths of slides (organization, preparation, sharing, etc.) • Mitigate weaknesses of slides(inflexibility, immobility, passivity, etc.) • Secure classroom adoption • Explore potential of computer-projected slides as mediating artifact • Prepare for more ambitious interventions Steve Wolfman Technology, Education, and Interaction
Presenter Strategy • Use TabletPC affordances (high-quality ink, wireless, portability) • Focus on instructor first(single, necessary point of adoption) • Distributed architecture & flexible rendering to support extensions Steve Wolfman Technology, Education, and Interaction
Technological affordances: High-quality ink, wireless comm., portability Steve Wolfman Technology, Education, and Interaction
Classroom Deployments Spring ’02–Summer ’03 studies: • 21 courses • 15 instructors • 1,000+ students • Intro to Master’s across CSE • University of Washington, U. of Virginia, & U. of San Diego Steve Wolfman Technology, Education, and Interaction
Student/Instructor Reaction • Positive comments and repeat use by instructors • Instructor survey: N = 9 • Student surveys: N = 479 Omits all project participants. Steve Wolfman Technology, Education, and Interaction
Instructor innovations and suggestions • “Donahue” Tablet • Instructor notes • Improved navigation (filmstrip and previews) • Collective brainstorming Steve Wolfman Technology, Education, and Interaction
Instructor view with notes Displayed view without notes
Slide previews with navigation Steve Wolfman Technology, Education, and Interaction
Conclusions • Designed effective & adoptable system supporting HCI/ET research To summarize all of that to one bullet point… Steve Wolfman Technology, Education, and Interaction

Expected Use SmallTalk, Self, Cecil, Java, C# Steve Wolfman Technology, Education, and Interaction
Actual Use Steve Wolfman Technology, Education, and Interaction
Study Motivators • Unexpected style of ink use • Feature discovery issues • Unexpected feature use • UI problems AM Marginal diags w/out min Hygenic erase Unintended scrolling Steve Wolfman Technology, Education, and Interaction
Ink Study Interpretive analysis [Erickson] of 3 courses: • Distance courses (, A/V and ink archives) • “Slideware-style” • Experienced instructors Hello world! is 14 strokes Steve Wolfman Technology, Education, and Interaction
Prevalence of Attentional Marks Segmented strokes from six hours of lecture into coherent episodes and coded into four categories: Steve Wolfman Technology, Education, and Interaction Will also briefly come back to this.
Understanding Attentional Marks Properties: • brief, simple markings • occur with speech • augment meaning of speech • ad hoc form Is there a linguistic context in which to understand these marks? Steve Wolfman Technology, Education, and Interaction
Hand Gestures Hand gestures [McNeill]: • are synchronous w/speech • are co-expressive w/speech • are global-synthetic/non-combinatoric • lack standard of form Attentional marks share these properties. Steve Wolfman Technology, Education, and Interaction
Gesture Types: Iconic First of five gesture types direct representations Steve Wolfman Technology, Education, and Interaction
Gesture Types: Metaphoric abstract representations Steve Wolfman Technology, Education, and Interaction
Gesture Types: Deictic & Cohesive Steve Wolfman Technology, Education, and Interaction
Gesture Types: Beats Insight into “other”? BRIEF & emphasize framework helps understanding. SEGUE: also helps understand breakdowns… Steve Wolfman Technology, Education, and Interaction
Persistent Representation vs. Ephemeral Meaning Steve Wolfman Technology, Education, and Interaction
Persistent Representation vs. Ephemeral Meaning Steve Wolfman Technology, Education, and Interaction
Design Recommendations • Non-homogenous color to distinguish strokes • Age cues to indicate co-occurrence and preserve ordering • Incremental rendering for process information Steve Wolfman Technology, Education, and Interaction
Conclusions • Designed effective & adoptable system supporting HCI/ET research • Identified important patterns of ink use and framework for understanding ink use Steve Wolfman Technology, Education, and Interaction

Richer Mediating Artifact CSCL has been “a move from ‘sage-on-the-stage’ … to ‘guide-by-the-side’”. New CSCL systems will be “much more like the ‘conductor-of-performances’ for an orchestra: students … [will contribute] to an overall performance.” [Roschelle & Pea] Leader-of-theater? Steve Wolfman Technology, Education, and Interaction
Goals of Structured Interaction Presentation System (SIP) • Mitigate more PowerPoint evil • Support intuitive and flexible design • Facilitate interaction in class • Enable new kinds of interaction Support the design, use, sharing, and reflection on the “orchestra’s” score. Passivity, simplification “transitions”, apprehension e.g., data reuse, intentional grouping, DHC Steve Wolfman Technology, Education, and Interaction
