Supplementing Tegrity/MSL
IncludeVHS/DVD

Integrate with ITV
Issues and Considerations Goal is to capture “live” presentations,
but presenters want to do post-production edits
Tegrity provides limited editing The typical class is too long (2-3 hours)
Limit to from 10 to at most 20 minutes Provide instructional designer assistance
Video/Visual content and accessibility Tegrity enables closed captioning
Issues and Considerations
High quality recordings require high bandwidth
Consider distributing content via CD and accessing via “off-line content” in Bb
Some “cognitive overhead” comes with the technology
Provide an operator to assist instructor Budget and/or charge back for costs of
replacement technology and operator

The Notre Dame Approach The Notre Dame Approach allows those with
small budgets or a need to quickly capture a class the ability to do so easily with little or no infrastructure and experience required.
Asynchronous learning, both Local and Distant Low-cost Manually intensive Flexible Easy to learn Primarily for class archival in large classes No live capture and distribution Little infrastructure needed
Who Is Using This at Notre Dame?
Executive MBA Program Students only on campus once a month Needed courses delivered when not on campus
Physics International study abroad program Required course 7 students spread throughout Europe, 6 on
campus Needed same day access to class
Economics Archival for large intro classes for review and
those who missed class
