annotation asynchronous services (e.g. email) synchronous services (e.g. chat/office hours) personal selections (for teachers and students) archival services
Shibboleth
To personalize/localize access, NDSL advocates Shibboleth implementation
Consolidates administration Provides single sign-on capabilities Scaleable and capable of virtually any
identity management need.
Single Sign-on
Enables login into multiple resources with a single username
What is Shibboleth?
Shibboleth is software, more specifically referred to as middleware
Middleware is a layer of software that acts as a facilitator between a network and its applications, providing services such as identification, authentication, and authorization
Shibboleth was developed by Internet2/MACE. The current version is v1.2
Shibboleth in Middle Schools
Funded with an NSF/NSDL grant, Columbia University is investigating the feasibility of implementing Shibboleth in a pilot group of middle schools
Columbia is interested in partnering with schools in its local community
Implementing Shibboleth
Software (Free)
Web Server
Java Servlet Container
Login system (local identity management)
Agreement with federation policies
Partnership Possibilities
Integration of NSDL resources into middle school science teaching activities
Professional development opportunities to guide teachers and administrators in the most effective uses of internet technologies
Understanding district privacy policies, practices, concerns, and emerging technologies
Pilot implementation of Shibboleth
