  3. By way of introduction . . . What about you? Have you ever taken a course using . . . the Web? CBI? VTC or ITV? Correspondence? Are you a distance learning instructor? What media have you used?

  4. Different types of aircraft . . . Keep in mind . . . for different types of missions

  5. Different types of media . . . Keep in mind . . . for different types of learning objectives

  6. As an instructor . . . If you had your choice . . . One-on-one mentoring

  7. As an instructor . . . The next best thing . . . Classroom environment

  8. Overview • A few introductory Qs & As • What’s so great about satellite? • What are ATN, DETN, & GETN? • What is the ATN Advantage? • Where are we going? • How can we serve you?

  9. As an instructor . . . When required to use distance learning, satellite can preserve that classroom environment at little or no cost!

  10. Still a classroom environment . . . Interactive Television (ITV) • one-way video & two-way audio • via satellite ITV emulates the classroom at a distance

  11. A Variety of Instructional Methods • You can still do: • High-end graphics & motion video • Live, interactive learning exercises • Teaching interviews • Panel discussions • Guest speakers • Student interaction with the experts • Student-to-student interaction • And like the in-residence classroom, ITV integrates well with print & online media

  12. The Big Secret in DL Today, I’m letting you in on a Government-wide secret: Satellite is a cheap, fast, and effective way to meet distance learning requirements!

  13. So why the secret? • Satellite not frequently considered for distance learning because it’s often considered exotic and expensive • Little awareness of the benefits of satellite technology • Panacea syndrome—Web is the answer for all distance learning • Government schools model themselves after academic institutions that own no global network • Little awareness of its extensive use in corporate America and in Federal Government • . . . so who IS using satellite?

  14. Corporate Satellite Networks A.G. Edwards Anheuser-Busch Bank of America Boeing Caterpillar Channel One Cisco Dillards Edward Jones Federal Express Ford General Electric Georgia Pacific Harley-Davidson Hewlett-Packard Home Depot HUD Intel JCPenny Kroger Lowe’s Macy’s McDonald’s Merrill Lynch Microsoft Orkin Pfizer Safeway Square D Staples State Farm SYDA Unisys USPS Wachovia Bank Wal-Mart The larger the enterprise, the more efficient satellite becomes

  16. What’s so great about satellite? • Academic Effectiveness – Supports diversity of teaching strategies & proven methodologies to enhance learning effectivenessfor all levels of learning - Preserves & enhances the live classroom environment - More effective environment than office area for long courses - Low attrition, pacing assures timely completion • Cost effectiveness – For established networks, costs are a mere fraction of travel & per diem costs, no up-front development costs—ROI is immediate! • Advanced technology – Synchronous & asynchronous medium for distribution of high-quality interactive video, CBI, and print—bypasses Internet bottlenecks and network firewalls—reduces latency and security issues

  17. What’s so great about satellite? • Global reach – Instant communications to virtually unlimited number of locations world-wide • Rapid content dissemination – Content kept current through frequent or “on-the-fly” no-cost updating—no waiting for outsourced updating • Rapid deployment – Additional sites through rapid and inexpensive downlink deployment • Visionary approach – satellite applications consistent with industry best practices, including blended media (or precision learning) approaches: innovative enterprise-wide combination of traditional & new technologies (thinking outside of the Web—don’t put all your eggs in one basket!) When you want it NOW!

  18. Overview • A few introductory Qs & As • What’s so great about satellite? • What are ATN, DETN, & GETN? • What is the ATN Advantage? • Where are we going? • How can we serve you?
