  • Just to name a few!

4
Question
  • What situations in the world today are creating
    demand for wireless technologies and devices?


5
Demand for Wireless - Corporate
  • Need for Flexibility
  • Increased Mobility
  • People dont have time to attend classes
  • Need for just-enough, just-in-time training
    materials (integrating content into the context
    of the workplace)
  • Economics
  • Public Safety in a Post-911 World

6
Demand for Wireless - Educational
  • Must meet the needs of the digital natives
  • Solution to the Digital Divide Universal
    Access
  • Flexibility
  • Mobility
  • Economics

7
How the Wireless Classroom Works
8
Why Schools Should Implement Wireless
  • Potential for anytime/anywhere access
  • Mobility adds value to existing computer programs
  • Cost effective
  • Flexible configuration
  • Allows the use of PDAs and other devices in the
    classroom
  • Wireless is becoming pervasive schools should
    not be left behind
  • Wireless technologies support a wide variety of
    instructional practices (assessment,
    engagement)
  • Wireless networks leave more time for instruction

9
Advantages of Wireless
Handheld Devices
Wireless Networks
  • Portability
  • Mobility
  • Cost effective
  • Technology is improving rapidly
  • Flexibility
  • Easier install
  • Robustness - no wires to become damaged
  • Mobility
  • Scalability

10
Disadvantages of Wireless
Handheld Devices
Wireless Networks
  • Less powerful CPUs

  • Restricted power consumption
  • Smaller displays
  • Different input devices
  • Less bandwidth
  • Less connection stability
  • Less predictable availability
  • Safety and security

11
Device Topics
  • Comparison WiFi and Bluetooth
  • Popularity of wireless devices
  • PDAs
  • Student Response System
  • Tablet PCs
  • Printers
  • Remote Controls
  • Headsets

12
Wi-Fi vs. Bluetooth
  • The primarily standard for wireless network access
  • Focuses on providing wireless, high-speed access
    to the Internet or a local area network (LAN)

13
Bluetooth vs. Wi-Fi
  • Also, a wireless networking standard that
    provides connectivity via radio waves
  • (PAN) personal area networking solution
  • Focuses on linking business tools together
    (phones, notebooks, PDAs, etc)
  • Cable-replacement technology

14
Adoption of Industrial Age Technologies
15
Adoption of Internet Technologies
16
Wireless non-PC Internet access devices will
out-pace PC Internet access
Cell Phones
PDAs
PCs
17
Personal Digital Assistant
  • Is it possible to do serious teaching and
    learning on a PDA?
  • This depends on both thehardware and the
    softwareavailable.

18
Calendar / Task Assistant / Mini PC
19
Pocket Hyperchem
  • Pen-based interface
  • Standard functions for general, inorganic, and
    organic chemistry

20
Chemistry Assistant
21
Math Assistant
22
PDA for Medical Instruction
  • Research in 7 European Countries
  • Developed Standards
  • Resulted in EHR Electronic Health Record

23
Student Response System
  • Interactive classroom questioning
  • Completely Web-based system
  • Student feedback is anonymous
  • Data available for later analysis

24
Student Response System - Data
  • Student view is synchronized with classroom view
  • Multiple responses to the same question are
    blocked
  • Students enjoy the technology and become more
    active in their learning when handheld pocket
    computers are used in the classroom.

25
Clicker
  • Encourages attendance
  • Gives immediate feedback to instructor and
    student
  • Students pay more attention to the content

26
Tablet PC
  • Digital pen
  • Create and save handwritten documents
  • Save, search, and review
  • Convert handwritten notes into typed text
  • Annotate imported documents

27
Printers
  • Plug into the parallel port of a printer/copier
  • Power it on
  • Click "Print" on your mobile device and a list of
    Bluetooth-enabled printers/copiers will be
    displayed
  • Select the printer/copier

28
Remote Control
  • Combines two components
  • a powerpoint remote control
  • a laser pointer
  • Plug-and-Play

29
Headsets
Bluespoon" is a new wireless headset designed
for mobile phones, weighing less than 10 grams
.
Currently it is the smallest Bluetooth headset
available.

35
Holography
  • While virtual reality may be grabbing the
    medias attention, startling advances in
    holography are promising to bring true color, 3D
    images into our homes, schools, and hospitals.
    --David Pescovitz

Considerations for Developers
  • Intuitive operation and layout
  • File size not too big, not too small
  • Minimize clutter, keep pages short, and use
    simple images
  • More granular coverage of topics
  • Condensed explanations
  • Indexing and hierarchical structuring ?
