The Wireless Mixed Blessing

  1. 1. The Mixed Blessing of Wireless in the Classroom Hoke Wilcox, ETTC Columbus State University wilcox_hoke@colstate.edu
  2. 2. Top 10 Wireless Cities in the US 6. Atlanta, Ga. 1. Seattle, Wash. 7. Denver, Colo. 2. San Francisco, Calif. 8. Raleigh-Durham- 3. Austin-San Marcos, Chapel Hill, N.C. Tex. 9. Minneapolis-St. 4. Portland, Oregon Paul, Minn. 5. Toledo, Ohio 10. Orange County, Calif. Intel's 3rd Annual quot;Most Unwired Citiesquot; survey ranks the top 100 U.S. cities and regions for the greatest wireless Internet accessibility.
  3. 3. Wireless Technology Provides access to your school’s network and the Internet without Ethernet cables Wireless signal sent from a wireless access point (some are portable, some stationary) Laptops in the mobile lab have a wireless card built in to receive the signal (your school’s desktop computers do not)
  4. 4. Top 5 Misconceptions about Wireless 5. It’s totally wireless 4. We will never need wired connections again 3. It’s too slow to be effective in the classroom 2. It’s will connect my computer for miles 1. I can get the full 11 Mbps or 54 Mbps of connection
  5. 5. The Alphabet Soup of Wireless ! Standard Speed Compatibili Range ty 802.11a 54 Mbps No ** 802.11b 11 Mbps With g ** 802.11g 54 Mbps With a ** 802.11n* 100 -200+ Yes… ** Mbps *Standard not ratified, expected sometime late in 2006 or early 2007 ** Depends on structure and other environmental conditions
  6. 6. Wireless Networks
  7. 7. Wireless Networks
  8. 8. Advantages New Technology Classroom management issues Mobility Convenience File sharing Access to Internet resources Solving real problems with real purpose “just-in- time”
  9. 9. Advantages Supports interactive student activities Addresses multiple learning styles Allows students to stay in their “natural learning environment” while using computer resources Time saver with limited labs Input Devices
  10. 10. Advantages Class could be divided between many locations Classroom not limited to the four walls of the school You don’t have to share and the conditions of the computers are known More opportunity for interaction Teachers would be able to focus on the standards and meet the individual needs of the students
  11. 11. Advantages provide network access in large open areas such as libraries, halls or theatres support sports training or athletics competitions provide network access in heritage buildings allow rapid deployment of extra networking for special events (e.g. open days, parent evenings, drama performances)
  12. 12. What Does the Research Say? Impacts of the One-to-One Computing Initiative on Students, Teachers, and Families from Interviews. Greater access to resources and information for more students and families. Increased student motivation, engagement, interest, and self-directed learning.
  13. 13. Impacts of the One-to-One… More flexibility for teachers during instruction. Increased professional productivity and greater collaboration among teachers. Improved home-school communication. An increased need for planning time to make good use of the laptops. Added challenges for teachers to manage classrooms and discipline.
  14. 14. Impacts of the One-to-One… Easier access by teachers and students to up-to- date instructional content. More student interaction with teachers. Better-organized students. A Study of One-to-One Computer Use in Mathematics and Science Instruction at the Secondary Level in Henrico County Public Schools http://www.ubiqcomputing.org/FinalReport.pdf
  15. 15. Disadvantages Throughput Issues New Technology Cold Spots vs. Hot Spots Tech Support Issues (loading and unloading carts, relatively fragile) Input Devices (wires)
  16. 16. Disadvantages Classroom management issues Need Ethernet drop and electrical outlet unless AP’s are mounted Battery life High set up/clean up time
  17. 17. Barriers from Henrico County Public Schools Teachers, students, and administrators also identified several barriers or problems that complicated the implementation of 1 to 1 Laptop durability Laptop battery life Students’ forgetting laptops Management and discipline issues Time
  18. 18. Battery Usage in Laptops HP Pavillion ze2001 iBook 12quot; PowerBook G4 Dell Inspiron 6000 15iquot; PowerBook G4 HP Pavillion Dv4000 Dell Latitude X1 Gateway m520x 0 1 2 3 4 5 6
  19. 19. Equipment and Hardware Steel cart Shelving Locks Power Strip
  20. 20. Equipment and Hardware Wireless Access Point Ethernet cord Electrical cord
  21. 21. Equipment and Hardware
  22. 22. Know your laptop! Power Button
  23. 23. Peripherals BE AWARE THAT SOME LAPTOPS DO NOT COME WITH: •FLOPPY DRIVES •INTERNAL CD DRIVES
  24. 24. Input Devices A normal laptop keyboard will be smaller than the standard ones you use on a desktop. Some might not have the F keys and some might require combination key strokes to perform some tasks. You can attach a regular keyboard and mouse to most computers. The only question is what type of connections does your laptop have.
  25. 25. TEN YEARS AFTER THE BIRTH OF THE INTERNET, HOW DO AMERICANS USE THE INTERENT IN THEIR DAILY LIVES? http://www.stanford.edu/group/siqss/ SIQSS_Time_Study_04.pdf
  26. 26. TEN YEARS AFTER THE BIRTH OF THE INTERNET… “The Internet is, perhaps more than anything else, a means of communication – about 57% of the time on Internet is spent on email, instant messaging, or at chat rooms. Of this 57%, work-related communications constitute about a third, communication with friends constitutes almost a third, and communication with family constitutes about a sixth.”
  27. 27. TEN YEARS AFTER THE BIRTH OF THE INTERNET… “Younger people, between 18 and 29 years of age, seem to favor interactive forms of online communication: They use email less than older people, but they use instant messaging and chat rooms more. Social networking is used most by the youngest and the oldest (age ranges 18-29 and over 60).”
  28. 28. Ideas for Implementation Build up to 1 to 1 Two Power supplies and or batteries per machine Plan B (extra laptop or computer just in case) Utilization of School Network Applications Word Processing, database, spreadsheet, multimedia, and thinking software used for project based learning Development of electronic portfolios Teacher-created activities that supplement text books and curriculum
  29. 29. Ideas for Implementation Access to the Internet for: Research Interactive Skill Practice Simulations Virtual Trips Scavenger Hunts Communication with students around the world Web Cams/Streaming Video Tutorials
  30. 30. Ideas for Implementation Ability to move to authentic learning environments Collaboration with peers inside and outside the classroom Using Blogs as “digital paper” http://frogtech.blogspot.com/ Using Podcasts ??
