Memex Metadata (M2) for Student Portfolios
m 2 goals and motivating factors
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
project design and accomplishments
Project Design and Accomplishments
  • Developed a working system for field testing
        • Tablet PC, w/ standard software—MSWord, 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
metadata development continued
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
base component for documents and events


Generation methods

A = Automatically generated

D = Derived

H = Harvested

M = Manually generated


R = Required

O = Optional metadata

*The R/O designation only refers to manually generated metadata


Base-component for Documents and Events
usability study design
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

  • 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 UNC’s technology advisory groups

next steps
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
