Insights Into Our World
Our Driver for Everything: Shared vision of Excellent Learning Environments
Our Purpose: Meeting the learning needs of all 21st Century Learners
Our Approach: IT governance (congruent with concepts found in the CoBIT framework)
An Example: SSDZ - how we ensure we are delivering the right IT services

Unique K-12 Challenges
Post secondary and corporate environments are very different than the K-12 world
The principle of “in loco parentis” applies - Legally we are acting in the place of the parent
![Page 6: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/6.jpg)
Twelve Research-Based Elements of ELEs
1. Outcomes are clear to the student.
3. Where are students relative to the outcome…a pre-assessment phase?
10. Final evaluation on authentic compilation of assessment devices
5. Revisit outcomes to think about Instructional design. (Learning styles, complexity)
2. What evidence will show that students have met the outcomes?
11. Plan to assist students when the outcome is not being met… a new course of action
4. What does good learning look like? (Rubrics and exemplars)
6. Selection of input structure. (Strategy tool A)
7. Student opportunity to interact with new knowledge. (Strategy tool B)
8. Student opportunity to experiment or use new knowledge. (Strategy tool C)
9. Constant assessment feedback so students can modify learning efforts.
12. Classroom structure, peer relationships, culture of school and student strategies.

Our Beliefs on the Role of Technology
Jim Collins – “Good to Great”: “An accelerator”Prewitt in CIO: “The best leaders are those who
focus on a handful of useful technologies and ignore the rest, no matter how exciting the bandwagon looks.” October 2002
In Wolf Creek, we believe that the ongoing use and integration of technology is very much a component of basic literacy
![Page 8: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/8.jpg)
Connected Kids
For 21st Century Kids, technology is more than a tool… it is an essential component of everyday life that frames their social world view
For them, being digitally connected is as natural as speaking is to us
But…
![Page 9: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/9.jpg)
The Disconnect
Young people lack an adult perspective on safety, responsibility and general citizenship
Consequently they have an underdeveloped sense of risk and responsibility
Unfortunately those in the best position to guide them, adult mentors, often find themselves to be strangers in a strange land
![Page 10: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/10.jpg)
School 2.0
As Educators We Have Three Choices:
• we can try to ignore the shift• we can be reactive and try our
best to accommodate the shift• or we can be proactive by
embracing and harness the shift In reality we only have one choice
![Page 11: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/11.jpg)
The Missing Piece
While many laud the advantages of increased connectivity, few seem to take a full 3600
approach that addresses Digital Citizenship
![Page 12: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/12.jpg)
Enabling Technologies
How do we ensure we are deploying the right technologies?
In a Word – GovernanceFive-year vision: how will decisions made today
look in five years?

SSDZ – Enabling Personally Owned Devices
Pedagogy Design Goals:• Ensure digital citizenship concepts and expectations
are well understood by staff, students, and parents• Embed digital citizenship behaviours as a natural
part of school culture• Enable pedagogy and learning environments that
foster 21st century skills including collaboration, communication, knowledge creation, global awareness and reach, creative problem posing and solving, critical thinking…
• Leverage and embrace the tools that students already have and the environments that students already understand and populate
![Page 16: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/16.jpg)
SSDZ – Enabling Personally Owned Devices
ALU Safe-NAC Technical Design Goals:• 100% availability for any device/platform (OS) anytime
(reliability, AP density, 2.4 Ghz and 5 Ghz, infrastructure capacity, other…)
• Authenticated, logged/monitored access• Simple authenticated guest access (Captive Portal)• Auto-connect for regularly connected wireless devices• Dual layer access for personal devices (basic filtered
ISP then direct access to core resources after HIC check)
• Protect non-HIC personal devices from each other • Non-filtered access for special occasions• Same parameters for both wired and wireless access• Make experience as seamless as possible with minimal
loss of instructional time

SSDZ Readiness Tour
Met one-on-one with every school admin team to:• Explain how all four SSIDs work, particularly SSDZ• Identify support structures (school and district)• Review school approach to DC (students, staff,
parents)• Discuss the pedagogical changes that teaching in a
connected environment necessitates• Re-think current cell phone policies• Contemplate decommissioning the content filter• Encourage participation in a community of practice
within Wolf Creek
![Page 22: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/22.jpg)
Cost Considerations
• Some envisioned that enabling student-owned devices would save costs
• SSDZ was not implemented to reduce the need to buy PCs
• Instead the intent is to increase access and embrace the mobile revolution that is likely to supplant the PC as the preferred connectivity device
• Yes, there may be less need to purchase PCs• But, clearly more need for bandwidth and
robust infrastructure
![Page 23: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/23.jpg)
Cost Considerations
Similarly…• Videoconferencing wasn’t implemented to
save costs – it was implemented to serve student needs (and save schools)
• VoIP did save operational costs, but the main driver was increase service levels and opportunities to communicate and collaborate with parents and other staff
![Page 24: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/24.jpg)
What’s Ahead…
• We will witness a significant shift towards increased support for personal devices
• Standards, a long-standing strategy – will sometimes end at the network demark point
• Our focus will be on a robust infrastructure and well-supported services – the 4:1 minimum ratio is under review
• Consumer-oriented devices of personal choice will define the end-point (and the support structure)
• Cloud applications such as GoogleDocs may (eventually) supplant locally installed applications (Wolf Creek Google domain is in the works)
• Bandwidth demand will grow exponentially
![Page 25: The Wolf Creek Way Safe-NAC and the Use of Personal Devices in a K-12 Learning Environment Interop 2011 ALU Presentation Creating Success For All Learners.](https://reader035.fdocuments.in/reader035/viewer/2022062809/5697bfe81a28abf838cb6681/html5/thumbnails/25.jpg)
On The Horizon
• User agreements will have to morph into something that is actually intended to be read
• Privacy concerns will become an even more significant challenge in the days ahead
• Digital Citizenship is and will be of paramount concern
