LONCAPA at Ohio University Mark Lucas Dept of

LON-CAPA at Ohio University Mark Lucas, Dept of Physics and Astronomy Outline: • History • Usage • Resources • Issues

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

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)

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

Resources: Winter • December: $20, 000 total – 4 Dell Power. Edge 2650’s – Dual 2. 0 GHz Xeons – 2 GB RAM – 1 with RAID – Tape backup – APS, switch, etc…

Libraries and Resources • Worked on translator with Guy • Serway, Tipler, p 200, p 250 • Published domain-only for QC and proprietary issues • Talk to me if interested in some of P 200 problems • Beginning work on public Physlet library

Organization of Courses Users: • P 200 – course sequences, quarter by quarter • OUp 200 lib – 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 – http: //loncapa. phy. ohiou. edu/help

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
