Some history
 Usage of video and other media in student teacher training since 1999
 Video as self-assessment tool for student teachers
 record their educational practice
 review the recording
 annotate relevant scenes
 discuss scenes with fellow students
 Many tools developed since then
 Now: re-implementation and integration in our University‘s LMS

Pedagogical Use Cases for Video Annotations
 Many useful application scenarios for application of video
annotations in higher education
 Different goals, different settings, different camera perspectives
1. (Analysis) of Talks and Presentations (one camera perspective)
2. Analysis of Movies (one camera perspective)
3. Analysis of Teaching Strategies (two camera perspective)
4. Analysis of Job Interviews (two camera perspective)
5. Software Development: Requirements Analysis (two cam. per.)
6. Analysis of Group Work (four camera perspective)

Scenario: Analysis of Teaching Strategies
 Recording of individual teaching practice and collaborative analysis
in a seminar are core parts of teacher training in Paderborn
 University course is conducted in cooperation with local schools
 University tutors and experienced school teachers are the
supervisors
 Three phases of the Seminar:
1. Learning to prepare lessons in Computer Science
2. Performing lessons in Computer Science and learning to reflect
them
3. Reflecting again and generalise practices

Technical requirements
 Re-engineering of existing tools (Java, .NET)
 Need for a more platform independent solution
 Incorporation of streaming technology
 RIA as desktop application
 Decisions
 keep the good (ANN files), remake the rest
 Adobe Flex and AIR over JavaFX
 Wowza Media Server over red5 and Adobe Flash Media Server
 Streaming over RTMPS
 H.264 as video codec

The koaLA LMS and its extensibility
 koaLA (co-active learning and working environment) is the widely
used LMS at the University of Paderborn, based on sTeam
 focuses on individuals and individual cooperation contexts
 provides configurable knowledge spaces
 incorporates Web 2.0 technology and
functionalities
 aims at reducing media discontinuities
 flexible extension mechanism allows
development of new tools for
specific learning scenarios
