LON = LearningOnline Network (1)
Providing high quality learning content in an online environment is time and cost intensive
Typical scenario today:
• Online material is developed by only one instructor
• Online material is used by only one instructor
• Online material is used in only one course
• No assessment of learning effectiveness
Ineffective use of time and resources
LON-CAPA, W. Bauer, APS Montreal March Meeting
Much better scenario:
• Online material is developed and reviewed by more than one instructor
• Online material is shared among instructors
• Online material gets used across many courses and disciplines
• Continual assessment of learning effectiveness
LON = LearningOnline Network (2)

LON = LearningOnline Network (3)
We have built:
• a cross-institutional cross-disciplinary content repository
• a tool to seamlessly assemble this content
• a course management system to readily deploy this content

NetworkNetwork of connected servers
Any server in the network can serve sessions for any user
Content replication in background
Network-wide persistent URL paths

CAPA Computer-Assisted Personalized Approach
Online assessment with immediate feedback and multiple tries
Different students get different versions of the same problem
• different options
• different graphs or images
• different numbers or formulas

CAPA
Same problem, two students

CAPA
Benefits:
• learners can work together without just exchanging the answers
• learners get immediate feedback on their learning progress
• instructors get immediate feedback on their learners’ progress
LON-CAPA, W. Bauer, APS Montreal March Meeting21
CAPABenefits, cont.:
• cost-savings in routine grading
• instructor time used for instruction, not grading
• LON: shared problem library, de-facto setting standards and establishing
• LON: cross-course cross-institutional dynamic metadata
