M2 Goals and Motivating Factors
  • Explore student portfolio management
  • Integrate new technology and learning science
    knowledge
  • Reflective learning (3 minute paper, journaling)
  • Generate and use metadata efficiently and
    effectively
  • Metadata/tagging/annotation supports retrieval
    and other functions (preservation, management,
    use provenance)
  • Poor metadata
  • Context awareness

8
Project Design and Accomplishments
  • Developed a working system for field testing
  • Tablet PC, w/ standard softwareMSWord, OneNote,
    MLB, SenseCam, GPS device, Digital Camera)
  • MLB pre-populated with Course materials, Web
    pages, etc.
  • Pilot tested MLB and SenseCam technology
  • Developed an usability study pending IRB
    approval
  • Conducted an exploratory behavioral study
  • Ethnographic study of approaches to information
    in biology education (Manual note-taking
    reliance on class Website)
  • Developed a modular metadata scheme
  • Interoperable with CAF
  • Begin to study metadata creation and use
  • Publications and presentations

9
Metadata Development continued
  • Modular scheme addresses three classes context,
    object types, and formats
  • Extends UNC CAF (Context Awareness Framework)
  • Base-level object type component identifies
    metadata for documents and events
  • Majority of element automatically generated

metadata The R/O designation only refers to
manually generated metadata .
11
Usability Study Design
  • Participant profile questionnaire
  • Tutorial to learn the use of Tablet PC, SenseCam
    camera, and MLB
  • Use these technologies to perform a field task in
    the Coker Arboretum on the UNC campus.
  • Complete a series of tasks using MLB (e.g.,
    create a collection, annotate images,
    search/answer question etc.)
  • MLB pre-populated with Course materials, Web
    pages, etc.
  • Build a plant log, as part of a plant
    identification exercise
  • Complete an interview about the uses of the
    tested software and technology

Challenges
  • Low quality of SenseCam images
  • Complaints from users even when taking in to
    account that it is only a prototype.
  • MLB installation has been labor-intensive still
    problems requiring resolution
  • .excitement among students involved in testing,
    other disciplines, and UNCs technology advisory
    groups

17
Next Steps
  • Pilot testing
  • Usability study
  • Continue to develop evaluation methods for
    SenseCam use, MLB usability, and reflective
    learning
  • NSF Proposal Technology-Supported Reflection
    and Metacognition for Biology Education, NSF
    CCLI Program
  • BioMemex
