  • 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
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
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
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
Resources: Fall
  • 3 Dell PIII 800 Mhz with 380MB RAM

libraries and resources
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
Organization of Courses

Users:

  • P200 – course sequences, quarter by quarter
  • OUp200lib – library – limited authorship
  • Serwaylib – library – limited authorship
  • Lucas – own play space
lessons learned
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
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
