Managed Learning Environment Project
Back-end Connectivity
• We have developed a Visual Basic
program that provides a secure
connection to institutional administration
systems
• It can return records in IMS Enterprise
Format (in XML)
• It can be configured to work in new
environments
Managed Learning Environment Project
ANGEL
• “Authenticated Networked Guided
Environment for Learning” is a DNER
project funded by JISC and lead by LSE
• We have created a User Manager, a
message router and started to interface
with WebCT and Blackboard
• LSE have built a Resource Manager
and linked it into their student portal
