    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

      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

        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)

             Effectiveness


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

     (spring) MSU students
     100,000 logins 16 days into the
     year
     1,000,000 logins by March, seven
     months into the year

      Integration of Computer
          Algebra System
 • LON-CAPA can already deal with
     multidimensional symbolic expressions
     through sampling

 • Integration of Computer Algebra
     System will allow more flexibility

 • Working with University of Applied                  QuickT ime™ and a
                                             T IF F (Uncompressed) decompressor
                                                are needed to see this picture.

              Current Funding
     Initially developed at Michigan State University

     Additional funding of CAPA by Sloan and Mellon
     Foundations

     Today funded by Michigan State University, partner
     universities, publisher and service contracts, and the
     National Science Foundation within the ITR and CCLI-
     ASA programs
