the problem and issues
The Problem and Issues
  • If we solve Access Problem (technology, bandwidth, training), other impediments to an informed citizenry still remain
  • Need critical evaluation of resources (reliability, authoritativeness, thoroughness, recency)
  • Need skills to pare down from information overload
  • Need critical thinking skills
  • Need to deal with different users having different backgrounds and capabilities
project dates staff
Project Dates & Staff
  • Summer 2000-Dec 2001
  • $1 million
  • Co-Directed by Aimée Dorr and Howard Besser
  • October 21, 2000 Summit (planning involved 20 people from Pacbell & UCLA)
  • Rest of project primarily UCLA
  • Coordinator Sheila Afnan-Manns (afnanmanns@gseis.ucla.edu)
the user
The User
  • Evaluative bibliography of literature and projects
  • Analysis of what we know thusfar from several different perspectives (curriculum design, library services, critical theory, information retrieval, user-centered design, …)
  • Examining model curriculum
summit 1 2 oct 21 2000
Summit (1/2)Oct 21, 2000
  • Bring widespread attention to the underlying issues
  • 360 professionals from education, librarianship, public policy, and industry
    • 15% Higher Ed faculty, administrators, librarians
    • 28% K-12 teachers, principals, superintendents
    • 14% public and K-12 librarians
    • 33% future practitioners, policy makers, librarians, educators
    • 8% business community
    • 3% government (governor’s office, state dept of Educ, …)
summit 2 2 oct 21 2000
Summit (2/2)Oct 21, 2000
  • Snappy video to highlight the problems (25 unsolicited requests to show video in 1st month after Summit)
  • Over 2 dozen exhibits and poster sessions explaining related projects throughout the country
  • Guest speakers (Alan Kay, Marcia Bates, Pat Breivik, Kathleen Tyner, Anna Deavere Smith, Tal Finney)
policy
Policy
  • information literacy standards
  • issues related to the "Digital Divide”
  • privacy and ownership concerns
  • ...
design issues
Design Issues
  • Examine factors that inhibit efficient and effective use of an information system
  • Examine how best to design systems to match the literacy levels, technological capabilities, and other characteristics of the user
  • Principles, Practices, and Guidelines for Good Design for Facilitating Access (screen design, searching & navigation, metadata & description, info structures & organization, usability testing, …)
  • Build Adaptive Systems-
good design principles
Good Design Principles
  • Promote good design practices throughout the Design community
  • Get the Design community to sign on to a set of Principles for Good Design-
  • Create Guides & Best Practices Documents-
possible good design principles
Possible Good Design Principles
  • Don’t disenfranchise users who have slow processors, older browsers, low bandwidth, visual impairment, etc.
  • Clearly note the recency of any information resource
  • Make sure that a user can easily determine what organization/agency created or contributed to an information resource
important dimensions to good design principles
Important Dimensions toGood Design Principles
  • screen design
  • searching & navigation
  • metadata & description
  • info structures & organization
  • usability testing
our resources related to good design principles
Our Resources related toGood Design Principles
  • Screen Design - The visual design of the screen can impact usability. Color, font, the use of images, and layout of screen elements are essential design components.
  • Searching and Navigation - Ease of navigation and search/browsing options are critical components of usability.
  • Metadata and Description - Good metadata and site description will help users find the appropriate website.
  • Information Structures and Organization - How information is organized and categorized shapes access. For systems with an underlying searchable database, the structure of the database itself will determine the outcome of searches.
  • Usability Testing - Includes resources on how to evaluate sites and on testing for usability.
build adaptive systems
Build Adaptive Systems
  • Build Systems that adapt the same back-end information to different user profiles (different knowledge bases, different technical capabilities, different cognitive structures)
  • User profiles may include advanced researcher in a particular subject area, general undergraduate student, high school student, …
  • Different profiles will need different user interfaces, navigation, searching vocabulary, file formats and sizes, ...

  • Purpose
  • Casual user
  • K12 student, lifelong learner
  • Information/hobby
  • Scholar/preservation
  • Business
  • (Colorado Dig Proj)
  • Cultural tourist
  • Casual user
  • Scholar
  • (CIMI)
adaptive systems what they ll do
Adaptive Systemswhat they’ll do
  • Can serve different audiences (general public, purposeful inquirer [cultural tourist], domain specialist)
  • Each profile audience will
    • see a level of discourse addressed to them
    • experience a user interface appropriate to their profile
    • use vocabulary they are familiar with
  • Yet all will be using the same back-end set of information
adaptive systems how they ll work
Adaptive Systemshow they’ll work
  • Passing search terms through a thesaurus to map specialist vocabulary to/from vernacular
  • Adapting vocabulary from curatorial language into common discourse; development of markup extensions to EAD/CIMI/CIDOC to allow description for different audiences
  • In general, specialized users will experience more text-based interfaces, while general users will experience more graphic/visual interfaces
adaptive systems development plan
Adaptive Systemsdevelopment plan
  • Research and experimentation
  • Profile 5-10 different user communities
  • Mechanize 2-3 different information delivery systems
  • Demonstrate the utility of this approach (proof of concept) for further research and design
suggestions for joint cdl ucla project
Suggestions for joint CDL/UCLA project
  • Use OAC/California Cultures Collection
  • Profile and construct a series of different front-ends for different audiences
    • Front-ends-
    • Target Audiences-
  • Evaluate
slide34
Profile and construct a series of different front-ends for different audiences:Front-ends to include
  • Screen design for searching and for display
  • Browsing, probably with some high-level categorization/grouping
  • Searching
  • Vocabulary mapped through thesauri
slide35
Profile and construct a series of different front-ends for different audiencesTarget audiences might include
  • 4th grade students
  • 12th grade students
  • 4th grade teachers
  • 12th grade teachers
  • University faculty
  • Some people outside the history/social studies sector
what does this all mean for info professionals
What does this all mean forInfo Professionals?
  • Good set of Design Guidelines
  • Feasibility of Adaptive Systems that deliver the same back-end info tailored to different sets of user needs
