Tablet PCs and the Electronic ClassroomRichard AndersonUniversity of Washington
1BackgroundDepartment of Computer Science and Engineering, University of WashingtonSince 1986ExperiencePhd., Stanford University, 1985Post doc, Math Sciences Research Institute, BerkeleyVisiting Professors, IISc, Bangalore, 1993Visiting Scientist, MSR, 2001Research InterestsEducational Technology, Pen Based Computing, Computing for the Developing World
2Integration of Student Devices in the Electronic Classroom
3What will the classroom look like . . .If all students have computational devicesLaptops, Tablets, Ultra light tablets, PDAs, Smart Phones, Gameboys . . . If the devices are all connectedIf the devices are all integrated into classroom instruction4Wide range of potential classroom applicationsPresentationDemonstrationSimulationAccessing external resourcesNote takingFeedbackActive learningPeer communication
5The Slide Based LectureWidely used in higher educationBut often criticized What are the good points?Provides structure for classSharing materials and persistent across course offeringsHigh quality diagrams and picturesMediating artifact for discussion
6What do good teachers do with PowerPoint?Use technology to leverage teaching skillsMaintain interaction with audienceAdjust presentation based on audience feedbackUse other mechanisms for altering displayed material7Ink in the ClassroomFlexibility to create contentRich expressionSymbolic and diagrammatic languagesShow processClassroom PresenterIntegrate digital ink and electronic slides on Tablet PC

16History of Classroom PresenterInitially designed as presentation system for distributed classroomInk and slides for flexibility in distance learning presentationStand alone presentationsIntegration with student note takingActive learning with annotations from students2001-2002 Project started at MSRCode released to UW to allow continuation of projectIntegration with ConferenceXPMSR license Multicast networking2006, CP3 releasedImproved network communicationBSD Open source license
17Classroom Presenter as a distributed applicationDesigned as distributed application for distance learningEnables many scenariosMobilityWalking and talkingSharing materials with students Note takingClassroom interactionStudent submissions
18Basic Usage, Higher EducationInitially targeting Computer Science ClassesPicked up by a wide faculty in a wide range of disciplines
19Discussion ArtifactUse student generated example to explore different aspects of a topicAssess overall understandingDiagnose misconceptions

The reason that two venues are used is that higher bandwidth is available between UW and MS so high bandwidth video goes into venue 1, and lower bandwidth (256kbps) goes into venue 240Classroom Activities
