21st Century student’s digital store
Student resources generated individually or collaboratively, specifically for a class (e.g., notes taking during class, paper drafts, project work).
Standard course resources (e.g., professors’ slides and lecture notes, whiteboard notes, readings, assignments, quizzes, exams, course evaluations)
Personal digital educational memories, captured via digital cameras, cell phones, email, IM (instant messenger) technology, and other pervasive technologies.

Summary of Motivating Factors
We want to stimulate reflection, metacognitive learning…
We want to be proactive in testing new technologies
Help students deal with information overload
Augment student memoryAugment student memory

Memex Metadata (M2) for Student Portfolios
To advance work in the areas of student learning, contextual IR, and digital portfolio management
Metadata issues►What metadata is needed to support ….?►What is the most efficient and effective means
generating metadata in this new learning environment?
– What metadata is required for an effective Memex?

Project Design and Accomplishments Information behavioral study biology students Developed a working system for field testing
– Tablet PC, w/ standard software—MSWord, OneNote, MLB, SenseCam, GPS device, Digital Camera).
– Pilot tested, usability study
Developed a metadata framework– Content, structure, context
– Emphasis on automatic metadata generation
– Extends UNC CAF (Context Awareness Framework)– OWL ontologies (person, room, context agents)
» SOUPA: Standard Ontology for Ubiquitous and Pervasive Applications
– Metadata use for contextual retrieval, annotation
M2 Metadata Framework
MLB/Student Digital Store (images, notes, Webpage, SenseCam digital memories/course material etc.)
Structure
XML
OWL
RDF
SOUPA
LOM/IEEE
Context
Data types: documents, happenings, people
Where? (GPS, RFID)
Who with? (Student, faculty…, FOAF)
What? (Class, study group, meeting, lab)
DC2006Manzanillo, Colima
M2 Metadata FrameworkContexts
–Determine education related context of students. Answering questions such as:
►What is the student’s location? (Physical location, from country to campus room number) (GPS metadata, RFID tags)►Who they are with? (Students, faculty, staff ) (FOAF)►What activity are they engaged in? (A meeting, study group, class, lecture, lab)
Data types►Happenings/Events: Lecture, Conversation, Project►Documents: Slides, Handouts, Student notes Quizzes, Exams, Papers, (have a format: text, html/text, gif, mpg, etc.) ►People (Student, faculty, staff profile)

Conclusions and next steps
Progress in understanding use of technology– Excitement and conflicts– MLB Limitations
Pilot testing, refining our test methods Continue to develop evaluation methods
for SenseCam use, MLB usability– Reflective learning– Metadata generation and use
