Experiences with CLIC

• Works well for recitation sections
• Most difficult making local students feel
  comfortable
• Faculty focus on camera
• Need to repeat student questions
• Computers in classroom distinctively mixed
  blessing ? compete with email and web

10
CISE infrastructure Staff

• Support servers, CLIC, networks
• Maintain software infrastructure
• Provide training for undergraduates

11
CISE outcomes - Leverage

• Encouraged Microsoft equipment gift of 1M for
  Win2K teaching project lab
• Caused 100k/year from provosts office
• Visibility ? school support for 1 FTE
• INTEREST networking lab

12
CISE outcome - CLIC

• Undergraduate research
• MS students
• Multimedia I/O equipment for variety of classes
  (visual interfaces, adv. Internet services,
  operating systems, )
• Local control of software and hardware
  infrastructure vital for non-standard projects
  and courses
• Better ability to teach programming recitations

Success Failure

• Wide variety of research results, from media
  acquisition, to transport/communication, to
  content generation and processing
• Integration across research efforts difficult,
  since research part of many NSF/DARPA/industrial
  projects

16
More or Different Resources

• More staff support
• Need cross-project programming and system support
• Cost of equipment ?, cost of staff ?
• Plan for equipment lifetime of 3 years
