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 Benefits & Savings Reduced large lecture hall usage Students have on-demand access to

lectures 90% of statistics students choose to

watch online Makes it possible to spend effort on lab

sections and discussions

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
