Educational Technology

…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

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

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.
