• Biggest Gain From Computers is Communication
• Computer Use is Between Classes (not during)
• Few Administrators Use Wireless
• Value Added by Wireless is Minimal
• Wireless Blackberry is Disappointing
• Students Often Drop Wireless Card Rental
• Biggest Gain From Wireless is Convenience

What We’ve Learned So Far
About Technology and Teaching
1. More Learning results From Better
Communication!
2. Students relish Buffets!
3. Blended Courses are Best!
4. Ubiquitous Access is Essential!
5. Simpler is Better!
6. Professor becomes Personal Trainer!
Progress Toward Realizing the Full Learning Potential
of Ubquitous Computing-- in Increments of Equipment

[Interpretation of chart: 10% of the value is achieved when the instructor only (bottom line) has a computer.
Another 5% is added, for a total of 15%, when all students can get to computers in a public lab. …
100% of the value of ubiquity is achieved when everyone has access everywhere.]

Conclusions
• Fully Interactive Learning Can’t Take
Place Until Everyone is Connected!
• If the Most Economical Means of
Connecting is Wireless, Do It!
• Go For 802.11A if You Can Afford It
• Tom Franklin is an expert worth hearing
15
Conclusions
• Wireless is currently a technology still
in search of a killer application.
• The Killer Applications will likely be--– Email & Instant Messaging EVERYWHERE
– Global Positioning
• We’ll be closer when we have signals from the sky &
community computing
• Wireless may slip in the back door by becoming the
backbone of campus systems
• In the meantime, boutique applications will intrigue
all of us.
16
As Wake Forest sees ahead…
• Wait for 802.11A (agree with Franklin)
• Move from Wired-with-Wireless-Add-On
to Wireless-with-Wired-Add-On
• No Big Rush to Wireless
17
Actions for You to Consider
•
•
•
•
•
•
•
If not wired, go local wireless.
Include voice wireless (cell phone)
Support boutique uses as “add on”
Encourage community-wide computing
Stand ready to leapfrog the pioneers
Invest cautiously
Celebrate the brave innovators!
