Integration of a Video Annotation Tool into a Coactive Learning and Working Environment

University of Paderborn Computer Science Education Group

Johannes Magenheim (presenter) Wolfgang Reinhardt, Alexander Roth, Matthias Moi, Dieter Engbring

  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

Some history

2

  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)

Pedagogical Use Cases for Video Annotations

  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

Scenario: Analysis of Teaching Strategies

Reflection on Classroom Work

  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

  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
