  1. The Use of Computers in Physics Education- Online Materials and Systems for Teaching Gerd Kortemeyer Assistant Professor of Physics Education Adjunct Professor of Physics Michigan State University

  2. Schedule • Presentation: The LON-CAPA System • Sample Course: Introductory Physics, Mechanics • Course Coordination: How to assemble and run a course • Authoring: How to author online resources, including homework • Later session: using computers for data collection in a student physics lab

  3. IMPORTANT • Please ask questions anytime • Just raise your hand

  4. Presentation Outline • What is LON-CAPA? • Learning Content Management • Content Repository • Content Assembly • Course Management • Assessment • Open Source and Free • Does it work? • What’s Next?

  5. LON-CAPA What is LON-CAPA?

  6. LON-CAPA • Learning Content Management System • Assessment System • Open-Source and Free

  7. LON-CAPA • Learning Content Management System • Assessment System • Open-Source and Free

  8. LearningOnline Network • LON-CAPA learning content management is: • a cross-institutional cross-disciplinary content repository • a tool to seamlessly assemble this content • a complete course management system to readily deploy this content

  9. Bottom:Content Repository “The aisles of your supermarket”

  10. Bottom: Content Repository

  11. Bottom: Content Repository • IMS Import from other course management systems • IMS Export WebCT 4.0 Campus Edition Vista BlackBoard 5.0 LON-CAPAContent Repository and Courses IMS Package

  12. Bottom: Content Repository • Currently links 3 middle schools, 44 high schools, 5 community colleges, and 37 universities • 38,300 content pages • 52,600 homework and exam problems • 49,300 images • 6,600 content assemblies • 1,100 simulations and animations • 500 movies • Publisher libraries, “back of the chapter problems”

  13. Middle: Resource Assembly

  14. Includes the two into her unit on conservation laws Writes module on energy conservation Writes module on momentumconservation Uses that unit in his course Middle: Resource Assembly

  15. Middle: Resource Assembly • Static metadata: Dublin Core, cross-walk to IMS • Dynamic metadata: use assembly data for recommender system:

  16. Middle: Resource Assembly • Ranked Search

  17. Top: Complete Course Management System • Course Navigation Tools • Communication features (discussion, thread) • Announcements • Portfolio space • Homework • Exams(online/offline)

  18. LON-CAPA • Learning Content Management System • Assessment System • Open-Source and Free

  19. LON-CAPA’s Approach • Online assessment with immediate adaptive feedback and multiple tries • Different students get different versions of the same problem • different options • different graphs or images • different numbers or formulas

  20. Same problem, two students

  21. Focus on Science and Math Combined HTML/LaTeX Source Configurable online rendering: As HTML As Image Using Mathtype fonts Compatible Compatible Requires browser config Low bandwidth High bandwidth Low bandwidth

  22. Focus on Science and Math Combined HTML/LaTeX Source Print: HTML->LaTeX PDF output

  23. Focus on Science and Math • Symbolic math grading

  24. Focus on Science and Math • Chemical formulas and structures

  25. Focus on Science and Math • Full support of physical units

  26. Focus on Science and Math • Dynamic Graphing

  27. Formative Assessment • Feedback to the student • “how am I doing?” • “what is expected?” • Feedback to the instructor • “how is my class doing?” • “what do I need to deal with, and what not?” • Just-In-Time Teaching(reading and problems due before class)

  28. Feedback to Instructor

  29. Feedback to Instructor

  30. Problem Analysis

  31. Formative Assessment: Peer-Teaching

  32. Formative Assessment • Individual learner help

  33. Summative Assessment

  34. Summative Assessment

  35. Turning Summative into Formative

  36. Turning Summative into Formative

  37. LON-CAPA • Learning Content Management System • Assessment System • Open-Source and Free

  38. LON-CAPA • Open-source free software • GNU General Public License • No license fees • Can be modified, extended, improved, adapted ... • Developed by educators for educators

  39. Runs on what? • Runs on Intel or AMD hardware • Approx. 200 concurrent sessions per server • Linux operating system • Standard free distributions: Fedora, SUSE • Enterprise versions:Redhat Enterprise Server • No additional database, etc, needed

  40. LON-CAPA Does it work?

  41. Effectiveness LON-CAPA is a tool, not a curriculum. Effectiveness depends on how it is used.

  42. Time on Task: 10,000 students x5

  43. Time-On-Task • Academic year 2004/2005 • Approx 12,600 (fall) and 10,800 (spring) MSU students • 100,000 logins 16 days into the year • 1,000,000 logins by March, seven months into the year • Approx 30,000 students systemwide

  44. Before/After Time-On-Task vs. Perceived Helpfulness

  45. Formative vs. Summative

  46. Formative vs. Summative

  47. Exam and Course Grades

  48. Gender Differential • phy231: traditional • phy232: CAPA

  49. LON-CAPA What’s Next?

  50. Formative Assessment in Class • In-Class Use of LON-CAPA • Partnering with Harvard (Mazur group) and Erskine (Junkin) on next generation “clickers”
