Lessons learned and status

• In production use in UW Professional Masters Program since 2002

• Other projects – UMass/Galloway, Australia Distance Education,

WWAMI Medical Education

• Multicast networking has been a challenge• Classroom setup especially audio is critical• Deployment in real classes has been critical for

moving the technology forward

Why use computers to support good pedagogy?

• Improved logistics and reduced overhead• Electronic activities allow digital integration

– Efficient display to class– Digital record

• Specific operations– Anonymous display and submission– Aggregation and analysis

• Natural extension of instructor presentation system

Tutored Video Instruction with Classroom Interaction

• Joint project between University of Washington, Beihang University, and Microsoft Research Asia

• Offer an undergraduate algorithms course using Tutored Video Instruction

• Instructor is in Seattle

• Time difference prevented a synchronous distance course

May 10, 2007 Latin American Academic Summit 26

Tutored Video Instruction

• Base course on facilitated use of recorded materials

• Materials recorded from a live class

• Facilitator guides discussion around materials

• Gibbons, Science 1977
