1 Wireless Computing Practical One-to-One Access On a Budget National School Boards Conference Denver, 2004

2 Two Factors that Determine Student Success with Technology Access Access Type of use Type of use

3 Questions for Leaders How to best resource our school/district How to best resource our school/district How to implement technology in such a way that its use is aligned with curriculum and effective practice How to implement technology in such a way that its use is aligned with curriculum and effective practice How to help teachers teach effectively How to help teachers teach effectively Help teachers teach more effectively through appropriate use of technology Help teachers teach more effectively through appropriate use of technology

4 Our Questions for the Day Resource allocation Resource allocation Mobile wireless versus traditional labs and center-based classrooms Mobile wireless versus traditional labs and center-based classrooms Usage / Implementation Model Usage / Implementation Model How does implementation model affect access and use How does implementation model affect access and use Many other questions Many other questions Handhelds, take-home, instructional strategies, other models Handhelds, take-home, instructional strategies, other models

5 Agenda One-to-one access One-to-one access Budget and access challenges Budget and access challenges How wireless can help meet challenges How wireless can help meet challenges Considerations for wireless Considerations for wireless Where wireless can help Where wireless can help Hardware and standards for wireless LANs Hardware and standards for wireless LANs Specific hardware and budgets Specific hardware and budgets

6 One-to-One True one-to-one is for every student, all the time True one-to-one is for every student, all the time Very expensive Very expensive Complete curriculum re-design Complete curriculum re-design A long and arduous process (just ask!) A long and arduous process (just ask!) Practical one-to-one in the real world Practical one-to-one in the real world One-to-one access on a regular, ongoing basis One-to-one access on a regular, ongoing basis

7 Why 1-1? (or other high-access models) Supports project/inquiry-based classrooms Supports project/inquiry-based classrooms Collaboration, communication, research, analysis, production Collaboration, communication, research, analysis, production Supports dynamics of everyday classroom Supports dynamics of everyday classroom Teachable moments Teachable moments Tech matches the ebb and flow of classroom discussion/lesson Tech matches the ebb and flow of classroom discussion/lesson Engaging Engaging Increases achievement ?? Increases achievement ??

8 Why Not 1-1 ? (or other high-access models) Technology emphasized over teaching and learning Technology emphasized over teaching and learning Distracting from the learning process Distracting from the learning process Commonly there is insufficient training for teachers and students to be successful Commonly there is insufficient training for teachers and students to be successful Cost – benefit Cost – benefit Insufficient research on effect Insufficient research on effect Some indication that high levels of access decrease scores on standardized tests – at least initially Some indication that high levels of access decrease scores on standardized tests – at least initially

9 Implementation Models Research has not certainly shown the type of model that maximizes student achievement Research has not certainly shown the type of model that maximizes student achievement Center-based / model classrooms Center-based / model classrooms Traditional labs Traditional labs One-to-one access One-to-one access Are there ways to realize the benefits of a true one-to-one model at lower cost? Are there ways to realize the benefits of a true one-to-one model at lower cost?

10 Challenges (the case for practical one-to-one with mobile wireless) Shrinking budgets Shrinking budgets Provide adequate computer access when needed (ex: NCLB) Provide adequate computer access when needed (ex: NCLB) Limited availability of space Limited availability of space More accountability for use of equipment More accountability for use of equipment Results – greater alignment of technology with curriculum Results – greater alignment of technology with curriculum

11 Can Wireless Help the Budget? Wireless labs may be less expensive to install but may be more expensive to maintain (watch the TCO!) Wireless labs may be less expensive to install but may be more expensive to maintain (watch the TCO!) Fewer classroom computers needed Fewer classroom computers needed Traditional labs may not be needed – including the common lab facilitator Traditional labs may not be needed – including the common lab facilitator Wireless labs do not occupy a classroom – possibly saving on portable/modular building cost Wireless labs do not occupy a classroom – possibly saving on portable/modular building cost

12 Cost Comparison Cost Comparison Traditional Center/Lab vs. Mobile Wireless – 30 classrooms Cost Comparison Traditional Center/Lab Traditional Center/Lab Center-based classrooms with one fixed lab Center-based classrooms with one fixed lab 5 classroom computers, NetTV/projector 5 classroom computers, NetTV/projector 177 computers 177 computers $ 231,550.00 $ 231,550.00 Mobile Wireless Mobile Wireless 2 classroom computers 3 wireless mobile labs with 27 computers each No fixed lab 141 computers $ 170,973.00 $ 170,973.00

37 Performance Goal 3: Technology is integrated throughout the curriculum Performance Indicator 3.1: The number of schools in which all students are able to work from a networked computer. Student Access to Technology During the 2003-2004 school year, did ALL students in your school have access to a networked computer and were ALL students in your school regularly given the opportunity to do meaningful work from these networked computers, beyond use for drill and practice? Note: For a school to answer YES to this question would mean that the school environment is such that all students have regular use of a networked computer for learning and research and that the use is across multiple disciplines and classrooms and is consistent with the Louisiana K-12 Educational Technology Standards. (Computer use for drill and practice activities in a lab or classroom environment alone would not meet this condition.)
