This workshop will map the technological infrastructure for a personal learning network. It will describe the major protocols supporting personal learning and describe how third party applications (such as simulation engines or learning management systems) interact with personal learning environments. It will draw on the technology developed by the National Research Council’s ‘Learning and Performance Support Systems’ to create a testbed technology environment.

• 14:30 – 15:00 Core interaction elements in cloud technologies (APIs, REST.JSON, OAuth, and related core technologies)• 15:00 – 15:30 Underlying common e-learning technologies –
overview of xAPI, LTI and other e-learning tools interoperability• 15:30 - 16:00 Break• 16:00 – 17:00 Building the PLE environment: with knowledge of
e-learning interoperability technologies, we will ‘moot’ a PLE infrastructure

Introductions and Aliases• Split into five groups as assigned:• Users (slightly larger group)• Sponsors (who will pay to have it built)• Developers (who will actually build it)• Marketing (who will sell it)• Operations (who will keep it running)
10:00 – 10:30
![Page 6: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/6.jpg)
UsersChoose a person - yourself, your child, a person you know
• it needs to be a specific person with a name, age, place of residence, educational background.
Chose a context or environment - do you work at a law office? A grocery store? Are they a teacher? Are they a farmer in the field?
![Page 7: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/7.jpg)
SponsorsChoose a person who would pay for the system • What problem are they trying to solve?• Why would they be willing to pay?
Examples:• Company investing in training systems• College or university administrators• Government employment support official
![Page 8: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/8.jpg)
DevelopersChoose a specialization (don’t worry if you aren’t really a developer)For example:• Database engineer• User interface designer• Platform services
Ask yourself:• What information do I need to be able to do the job?• How does this look like products that already exist?
![Page 9: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/9.jpg)
MarketingSome roles and questions:• Business development• Copy writer• Purchaser / distributor
Some marketing questions to ask:• What’s the best business model? • How can it address client needs?• Where are the best channels to market it?
![Page 10: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/10.jpg)
Operations and Maintenance• How do we keep the product running?• How do we keep maintenance sustainable?• What roles need to be filled to manage these?
![Page 11: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/11.jpg)
Overview of the Concept of PLEs
PLE
LMS
MOOC
Blogger
Simulation
Chat Room
Intranet
Access to many services in one personal environment
![Page 12: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/12.jpg)
Properties of the PLE…• What information should it record?• Who owns the data? How private is it?• What should it do?• What would a person do with it?• Where, exactly, is a PLE located?
PLE
![Page 13: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/13.jpg)
The Network of PLEs
![Page 14: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/14.jpg)
The Social Network of PLEs
twitterfacebook
![Page 15: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/15.jpg)
Properties of the Network…• How do people find each other? Services?• How do they communicate? What do they
share?• How does a single PLE work with services?• Do we need centralized registries?
![Page 16: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/16.jpg)
Why a personal learning environment?• What is the value proposition for a PLE?• Note: value isn’t what you can do, it’s how you benefit• This is usually stated in financial terms (earn more, cost less)• Can also be stated in terms of quality: faster, bigger, better• And can be non-financial goods: satisfaction, happiness, memories
10:30 – 11:30
Many elements of the interactive exercises were drawn from Alain Désilets, Envisioning the Right Thing How to facilitate a collaborative project visioning workshop
![Page 17: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/17.jpg)
The Value Proposition…For: Target user
Who: Pressing needThe PLE is: Name and type of product
That: ‘Killer Feature’…. Reason to buy (or to pay for)
Contrarily to: Main alternativeIt allows them to: Distinguishing feature
![Page 18: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/18.jpg)
Value Proposition Workshop• Five new groups, each with a:• User• Sponsor• Developer• Marketer• Operator
• Draft value propositions and record them
![Page 19: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/19.jpg)
What is a PLE? • Elements of a personal learning environment (interactive exercise to
define major elements, e.g. resource network, personal learning record, learning assistant, analytics)• What we want to do here is to ask ourselves what a PLE will do• This involves asking why we want a PLE to begin with
So, back in your original groups, consider the following….
12:00 – 13:30
![Page 20: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/20.jpg)
What Role Does a PLE Fulfil?Role(s) Metric #1 Metric #2 Metric #3
As many roles as you want
![Page 21: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/21.jpg)
What Tasks Will Users Perform?Role(s) Task #1 Task #2 Task #3
Don’t Feel limited by only three tasks… make as many as you wantPut each task on its on PostIt note
![Page 22: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/22.jpg)
What Tasks Will Users Perform?•Task priorization process…..•Vote for the tasks you thing are most important• Yes, you may vote more than once•We will select the top dozen or so tasks
![Page 23: Developing a Personal Learning Infrastructure with Stephen Downes](https://reader036.fdocuments.us/reader036/viewer/2022062901/58f2bc161a28ab1d6e8b456d/html5/thumbnails/23.jpg)

OAuth, and related core technologies)

LPSS
LPSS is Built Around thePersonal Learning Record
Me
This is a new type of data – we call it the personal graph.
Each person has their own private personal graph.
The PLR contains all a person’s learning records, including:- certificates,
badges and credentials
- activity records, test results, scores
- Assignments, papers, drawings, things they create

Exercise: Plot Tasks Users tend to do the tasks on the left before the tasks on the right
Tasks at the top are easy to implement, and produce high value to the user
