•
•
Winter 2002 – Phys 202 (Lucas) (100)
Spring 2002 – Phys 203 (Lucas) (100)
Summer 2002 – Phys 201(Lucas) (40)
Fall 2002 – 201/251 – (Lucas/Ingram) (450)
Winter 2003 – 6 courses – all of physics
– 700 students
– Half of department faculty (about 12 of 25)
Typical Usage
•
•
•
•
•
Homework – start as CAPA replacement
Including ancillary notes, demos, etc….
No integrated online courses yet
Kerberos 5 – university authentication
Full use of online printing
Resources: Warm Bodies
• Mark Lucas – 50% Faculty/50% CAPA Sys Mgr
– Support hardware, OS, LON-CAPA, faculty training,
library maintenance, teach intro physics
• Prasenjit Sarkar – Undergrad Asst Manager
• Typically 1 graduate student/quarter
• Matthew Phillips – Chemistry Educational
Technology Specialist
(will handle some of chemistry support)
Resources: Other
• In contact with Center for Instructional
Technology in Learning
– Moral Support, some undergrad support
• Internal grant - $25,000 for hardware
– (took second try)
Resources: Fall

Libraries and Resources
• Worked on translator with Guy
• Serway, Tipler, p200, p250
• Published domain-only for QC and
proprietary issues
• Talk to me if interested in some of P200
problems
• Beginning work on public Physlet library
Organization of Courses
Users:
• P200 – course sequences, quarter by quarter
• OUp200lib – library – limited authorship
• Serwaylib – library – limited authorship
• Lucas – own play space
Lessons learned:
• Suggestion: publish locally first, libraries
evolve
– When comfortable with style and quality,
PLEASE PUBLISH with wider access
– Have been adapting as printing solidifies
• Need for lots of examples
• Login problems can be a time sink
– Working on more extensive login diagnostics

Future:
• Increase content use for Physics
• CCLI?
• Improve libraries and beginning publishing for
free use.
• Convince Chemistry to jump on board
• Re-visit CITL (Instructional Technology)
• Submit Bug/Feature reports
• Fix bug reports
