Creating New Histories of Learning for Math and Science Instruction: Using NVivo and Transana to Manage and Study Large Multimedia Datasets. Strategies in Qualitative Research Conference
What is the Wisconsin Center for Education Research? • 37 year old education research center • 350 faculty, staff, and students • 50 different projects - from single researchers to teams of 15-20 • $17.5 million annual budget • 89% federally funded research • Technical Services – staff of 14
Growing Importance of Multimedia Data in Research • TIMMS-R – over 200 hours of video of math and science classroom practices in each of the 7 participating countries • Multiple studies of comparative curriculum redesign – 300-500 hours of video per year across 4-5 years • 15,000 hour of video from a nationwide sample of children from birth to middle school to study the long-term impact of childcare
New Media Tools Emerge From Universities & Research Centers • Clan, SALT, Transana, and others from the U.S • MediaTagger, Sequence 5, Transcriber, ATLAS.Ti, and C-I-SAID emerge from European research efforts • EMU and the QSR tools are developed in Australia
Free Tools Don’t Scale & Commercial Stuff = $/£/¥/€/Etc. • Faced with the enormous sizes of many clinical video collections, standalone analytical tools don’t provide adequate collection management support • Commercial digital video management solutions cost between $30k-$150k for a system capable of handling 4-5TB of video • Lack of standards inhibits interoperability
Applying Analytical/Descriptive Coding to Linear Media • Video segment as unitary object • Interaction depicted by video has multiple phases that have temporal order and length • Multiple timelines – along the lines of a video editing tool – may be an answer • Small, extracted video segments embedded as data bites is another reasonable approach • Using colored shapes drawn on or embedded in media files • Multiple transcripts – different methods
Video Editing Tools Provide Possible Coding Interface • Synch’d video • Multiple transcripts • Management window • Use(r) rights
Features on the Drawing Board - Based on Current Technologies • Data cutter integration • Clip representation as URLs • Export out to free-standing dataset • Export to/import from CHATxml format • Server-based, phoneme-based text recognition for collection searching (FastTalk & BBN) • Visual object recognition and search (Oracle) • DRM & linked use models (METS & TalkBank)
