  1. LON-CAPA at Ohio UniversityMark Lucas, Dept of Physics and Astronomy Outline: • History • Usage • Resources • Issues

  2. History • CAPA: pilot Fall 1994 • Used in • All introductory physics (algebra and calc) • Physical Sciences • Introductory Chemistry • Delivery of assignments (no exams,quizzes) • Piloting LON-CAPA – Winter 2002

  3. Piloting • 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)

  4. 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

  5. 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)

  6. 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)

  7. Resources: Fall • 3 Dell PIII 800 Mhz with 380MB RAM • 450 students • Some load issues, but partially software • In general was doing okay

  8. Resources: Winter • December: $20,000 total • 4 Dell PowerEdge 2650’s • Dual 2.0GHz Xeons • 2GB RAM • 1 with RAID • Tape backup • APS,switch,etc…

  9. 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

  10. Organization of Courses Users: • P200 – course sequences, quarter by quarter • OUp200lib – library – limited authorship • Serwaylib – library – limited authorship • Lucas – own play space

  11. 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 • http://loncapa.phy.ohiou.edu/help

  12. 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
