How can education
researchers best use video data? People at all stages of the educational
enterprise are increasingly relying on video data to build case histories,
document instructional practices, track cognitive development, and develop
new curricula. The use of video and other related data—images of
student work, transcripts of dialogue, test scores, observational notes,
and the like—opens up new areas of inquiry and gives us new ways
of investigating traditional questions. However, the expanding role of
video and other accompanying multimedia data also presents new challenges
in data acquisition, management, analysis, and dissemination. The Digital
Insight project promises to automate elements of video data analysis that
are currently “handcrafted.” Because handcrafting takes hundreds
of hours, progress in the field is painfully slow. Moreover, it is almost
impossible for even closely related research teams to learn from each
other because their tools, and their associated methods, are often incommensurate.
The research and development proposed here will provide a level of consistency
in method and process that will have a profound impact on both research
and instruction in math and science education.
The overarching goal of Digital Insight is to help individual researchers
and teams researchers to bring the problems associated with analyzing
large collections of video data down to a human scale. Some studies of
curriculum impact, for example, may include hundreds of hours of video
during a single year. Equally challenging is that the questions researchers
are asking of these data are complex and difficult to answer using this
data in its original linear format – video tape. Digital Insight
provides a general model for managing the entire research process as well
as a providing set of tools designed to allow researchers to answer complex
questions based on randomly-addressable large video collections. Digital
Insight’s support of good content management practices will assist
users as they catalog their data, navigate through their collections,
annotate analytically interesting segments, and create links between these
annotated clips to for the visual chain of argument necessary to support
complex arguments.
The Wisconsin Center for Education Research (WCER),
the TalkBank Project, and the Data Intensive
Computing Environments group at the San Diego Supercomputer Center (SDSC)
have formed this partnership called Digital Insight to address these challenges.
Digital Insight will deliver a system for building histories of student
learning for use in education research and instruction. Individual system
components will be integrated into a coherent data management and analysis
system that will significantly expand the ability of researchers and educators
to assemble metadata-rich, historical/archival accounts of learning and
development. Digital Insight partners have developed video-analysis tools
and a research-based online workflow environment ready to support participating
research teams, as well as a prototype process model for supporting collaborative
research. Both the lead project sites and the participating research teams
are firmly committed to a robust case study design that calls on users
of the system to act as participant observers and reflect on both their
use of the tools and impact of the process model on their work. The project
deliverables for Digital Insight will provide the infrastructure to allow
multidisciplinary and multisite video-based research and teaching to become
a reality. With tools provided by Digital Insight and rigorous application
good human subject practices, video that is originally collected for education
research sponsored by WCER and its partner institutions can be repurposed
to inform the design of teacher education. Digital Insight developers
and participating research teams will use and augment these tools and
help develop and refine the process model as they create new research-based
materials for high-impact professional development, teacher educator training,
and instruction. Digital Insight will be an enabling technology for a
wide spectrum of education and will be portable to other fields in which
clinical video plays an important role.
