4

Project objectiveto instruct European media professionals on the possibilities that online distribution, particularly Streaming Media distribution, offers to the Audiovisual Industry

Introduction




5

Facts about SMT Project» Budget of EUR 157 K » Co-financed by EU MEDIA Training Programme 2007» Ran through January – December 2007 » 3-day, in-class seminar for 16 participants » 5-week, online course for about 20 participants

Introduction




• Experimentation of innovative educational models• Creation of learning artefacts• Interactive video for educational purpose• Leveraging streaming media potentiality

Research Topics




• Creation of a conceptual space-time» The teacher gets “out of the box”» Interaction with learning artefacts» Conceptual timeline

• Time is marked by a sequence of concepts

• Learning artefacts converge in a holistic approach» Use of multiple knowledge mediators» Allow learners’ immersion into the context

Pedagogical Implications




• Re-mediation of content» Scripts specifically written for streaming interaction» Purpose-built learning artefacts» Multiple presentation styles

• Take full advantage of streaming technologies» Engage learners through repetition and practice» Animations prompting learners’ interaction

Technological Challenges




• In-class training – three days, 16 participants» Frontal lectures, workshops, case studies» Knowledge gathering

• Development and testing phase» Contents, delivery format

• Online course – nine modules, 20 participants» 9 interactive video lessons» 7 group activities» 7 individual assignments» 1 final report

Methodologies




• Graphical User Interface specifications» Simplicity and usability» Blended Video and Slides working area» Intuitive set of tools (video, slides controls)

• Video stream / slides specifications» 150 Kbps bandwidth limit» Video – slides synchronisation (ActionScript 2.0) » Adobe Flash video files (.flv) / slides (.swf)

Interface design




• SCORM compliant LMS: Moodle• Flash video streaming server: Adobe FMS• Network performance optimisation

» Dynamic buffering techniques » UPV’s server and network reliability

System Architecture




• Slides requirements» To illustrate, explain, highlight concepts» To use properly animations and simulations» To prompt learners interaction

Slides design process




• Video stream traversing» Time based (seconds)» Slide based (cue points)

• Video and slide synchronisation» XML descriptor file containing

• Resource location• Cue points• Captions

Video stream synchronisation

Streaming media as educational model offers:» More interactivity» More repetition and practice» More presentation styles

Results




• Need to focus learners’ attention» Avoid information overload» Avoid knowledge mediators overlap

• Need for finely synchronised slides and video» Teacher gestures and slide animations» Textual information must match teacher’s diction

Conclusions




Areas of investigations concerned» Hypermedia» Conceptual timelines» Personalised, adaptive learning paths

Basis for further research
