Title: Connexions: Education for a Networked World

ConnexionsEducation for aNetworked World
  • Richard Baraniuk, Janice Bordeaux, Sidney Burrus
    Jennifer Drummond, Brent Hendricks, Geneva
    HenryDon Johnson, Elvena Mayo, Ross Reedstrom,
    Bill Wilson

2
Networked World
  • Computers and networks are everywhere
  • Universities lead society at large in adoption of
    information technologies
  • books
  • libraries
  • photocopying
  • digital email, WWW
  • 6000 years of experience with paper
  • What translates to bits?
  • What can be done better with bits?

3
Drawbacks of Paper Texts
  • Inflexible for students and teachers
  • off-the-rack learning
  • sequential coverage
  • disconnected books
  • discourages exploration bystudents and teachers
  • Static and inefficient for authors
  • glacial time-scale to develop and improve
  • minimal collaboration among authors
  • many texts rehash the same material
  • discourages potential authors

4
Connexions
  • New approach to authoring, course
    design, learning
  • free / open-content materials
  • rapid, collaborative authoring
  • flexible, dynamic course design
  • simple visualization and navigation of connexions
    between concepts, courses and curricula

5
Connexions Global Communities
  • Community
  • Openness

6
Enabling Technologies
  • Internet - World wide web - Web browsers
  • Email
  • Data bases
  • Version control software
  • XML
  • separation of presentation from meaning
  • seamless presentation of modules from different
    sources
  • integrated mathematical equations, chemistry
    formulae, musical notation,
  • supports many output formats (web, e-book,
    print, speech)

7
How It Works
8
Content Modules
  • Nuggets of information / knowledge
  • hyperlinks highlight connexions between related
    modules
  • self-contained for easy reuse in many courses
  • diverse ideas, methodologies, and examples
  • customized to match personal learning styles
  • Continuously updateable
  • Encoded in a coherent format XML

Module in Print

Course Composition
  • Instructor
  • selects from large pool of existing modules
  • organizes modules into a touring itinerary
  • customizes look and feel of course
  • adds annotations
  • Multiple modalities Course path can become a
    print or e-book on
    demand (Ex
    Kinkos) can even be read to the blind
    using speech synthesis technology

Collaborative Development
  • World-wide communities of authors
  • to continuously create, expand, revise, and
    maintain modules and courses
  • Open-content development
  • all content freely available to read, copy,
    modify, redistribute
  • models from software world Linux, Apache web
    server,

16
Advantages of Collaboration
  • Dynamic, up-to-date content
  • makes latest knowledge globally available
  • links global community of experts
  • High-quality content
  • peer review
  • pride of authorship
  • Cost-effective development
  • extremely time efficient
  • leverages efforts of a global community
  • each module reusable in numerous different
    courses
  • Drastically reduces author time commitment
  • more teachers will become authors
  • share excitement of participating

17
Benefits of Connexions
  • Instructors
  • Rapid course development
  • Integrated curriculum development
  • Simple to provide prerequisite knowledge
  • Better- motivated students

18
Our Vision
  • Connexions has great potential to revolutionize
  • teaching, learning, authoring
  • Goal take Connexions to critical mass on a
    global scale
  • massive base of high-quality content
  • numerous diverse subject areas in engineering,
    science, humanities
  • large, global communities of authors,
    instructors, students
  • scalable software and organizational
    infrastructures to foster collaboration among
    authors, instructors, students

19
Connexions Scope Unlimited
  • From electrical engineering
    to biology
    to philosophy ...
