insights into our world
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
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

twelve research based elements of eles
4. What does good learning look like? (Rubrics and exemplars)

5. Revisit outcomes to think about Instructional design. (Learning styles, complexity)

3. Where are students relative to the outcome…a pre-assessment phase?

2. What evidence will show that students have met the outcomes?

6. Selection of input structure. (Strategy tool A)

7. Student opportunity to interact with new knowledge. (Strategy tool B)

1. Outcomes are clear to the student.

12. Classroom structure, peer relationships, culture of school and student strategies.

8. Student opportunity to experiment or use new knowledge. (Strategy tool C)

11. Plan to assist students when the outcome is not being met… a new course of action

9. Constant assessment feedback so students can modify learning efforts.

10. Final evaluation on authentic compilation of assessment devices

Twelve Research-Based Elements of ELEs


our beliefs on the role of technology
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

connected kids
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


the disconnect
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

school 2 0
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

the missing piece
The Missing Piece

While many laud the advantages of increased connectivity, few seem to take a full 3600 approach that addresses Digital Citizenship

enabling technologies
Enabling Technologies

How do we ensure we are deploying the right technologies?

In a Word – Governance

Five-year vision: how will decisions made today look in five years?

ssdz enabling personally owned devices
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
ssdz enabling personally owned devices1
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
alu safe nac advantages
ALU Safe-NAC Advantages
  • Provides the ability to:
  • provide detailed audit of endpoint configuration
  • classify endpoints at the MAC layer
  • restrict or enable access based upon ACLs
  • utilize and leverage existing infastructure

wireless ssids
Wireless SSIDs
  • 1. WC-Secure
  • Wireless domain member devices only
  • 802.1x device authentication
  • same log-on experience as wired domain devices
  • 2. WC-Guest
  • Filtered Internet access only
  • Captive portal authentication
  • AD guest ID required
  • No device to device visibility
wireless ssids1
Wireless SSIDs
  • 3. WC-SSDZ (Student - Staff Device Zone)
  • pre-configured for auto connection to stage 1
  • Stage 1 access same services as Guest access
  • Stage 2 full access to core resources (printers, file servers, etc) after successful HIC check
  • 4. WC-Presenter
  • Authenticated raw Internet access extended to any AP upon specific request
ssdz readiness tour
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
cost considerations
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
cost considerations1
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
what s ahead
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
on the horizon
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
We live in a globally connected society

Our vision is to create Excellent Learning Environmentsthat ensure we meet our mandate to prepare our students for adult life

21st century learning is all about preparing young people to become caring, competent Canadians with the knowledge, skills, and attributes to be successful global citizens
