  2. Outline • Basic Internet Concepts • Brief history of the Internet • Overview of national networking initiatives • Implications for learning

  3. Information Highway • “We must build the second generation high speed Internet -- 1,000 times faster than today’s Internet…” • “ …transmitting information to school children… at the speed of light…”

  4. Digital Coding • Two symbol alphabet 0 1 • Binary ideal for electronics • Binary alphabet can encode any information

  5. Data • ASCII uses 7 bits • 1010111 is letter W • 1110111 is letter w

  6. Flowers

  7. Red, Yellow and Purple Flowers

  8. Multimedia Requirements (No Compression) • Voice[8,000 samples X8 = 64 Kbps] • Compact disk[44,100 samples per second X 16 bits X 2 = 1.41 Mbps] • Super VGA monitor [1024H X 768V X 8 bits = 6.3Mb] • Black and white TV [360 H X 288 V X 1 bit X 30 f/sec = 3.1Mbps] • HDTV [1280 H X 720 V X 8b/color X 3 colors X 60 f/sec = 1.33Gbps]

  20. Redefinition of Education Industry • For-Profit Higher Education • Redefinition of Boundaries with other industries

  21. Effective Learning • We learn by doing • Do then listen or read • We learn from personal failure followed by success • Try, fail, improve, … and learn • We learn from doers stories • We learn general principles from cases

  22. Technology Supports Effective Learning • Digital Libraries • On-line Experts • Simulation/Games • Collaboration Environment • Tracking and Evaluation

  23. Established Education Industry Challenges • Make Learning more effective regardless of form • Shift resources from support of old to new paradigms • Improve decision time • Eliminate artificial divide between practice and instruction • Provide a range of expert teachers otherwise unavailable • Shift emphasis from studying to doing • Many teachers for each student
