Learning Space Construction
1
Photos by Cyprien Lomas
Really “Scholarly Space”
Teaching & Learning plus….
Research, collaboration and portfolios
Principles
Embrace participant content creation
Simple integration of interactive options
Author(s) control presentation and workflow

Academic Spaces: Building Blocks
Simple Content Authoring:
Easy page creation (wiki-like)
WYSIWYG Editing
Templates (page and site)
Versioning
Enhanced with Academic Functionality
Interactive Widgets (e.g. assignments & feedback)
Allows integration of content and activities
8

Templates
Templates provide scaffolding for majority of users
But can be bypassed for advanced needs
Page Templates
Sections with (editable) content
Site Templates
Predefined pages and dashboards

Everything is Content
Not just files to share
Classic “resources” tool in Sakai (of course)
Discussion post, user profile, test questions
Taggable, searchable, linkable, portable, shareable
Unified content repository
Content not tied to site
Everything in one storage area
BUT: Sakai is not a full Content Management System
No complex approval workflows
No fancy layout capabilities
Everyone is an author in Sakai

Academic Networking
Academic Networking
People are important, but “friends” aren’t enough
Related content is also relevant, but not the whole story
Activity based
Who has taken the same classes?
Who is reading the same articles? Participating in similar discussions?

People

Academic Networking
A platform for exploration
We aren’t competing with Facebook
We do believe we need to drive R&D in this area
Linking networks together
Sakai to Sakai
Sakai, Moodle, Blackboard, D2L
Leveraging existing networks
Particularly LinkedIn and Facebook
Sharing profile and activity information
Creating apps on those platforms

Groups & Sites managed separately
Member of a group – People with something in common

Services need to respond to more customers
UX oversight is more complicated
Workflows built across services
Encourages presentation & service separation

Academic Workflow
Beyond Tool Silos
Academic work flows often cross tool boundaries
Anything can be graded!
Anything can be discussed!
This exists in Sakai 2
But it is too difficult and more needs to be done
Example: Instructor puts into syllabus an assignment to create a discussionpost that will be graded.
4 tools for both instructors and students!

Using Open Source
Don’t write our own code
If we can help it
Criteria:
Functionality
License-compatible open source
Open standard
Approachable community

Sakai and Apache
Sakai 3 Kernel built on Apache Sling
RESTful web development framework for content management
Sling incorporates Jackrabbit and Felix
Everything as content
Discussion post, User profile information, etc.
Components put Content into JCR Content store
Sakai Kernel creates relational indices in DB
Component doesn’t need to do anything
Automatic tracking of most events by kernel
30

Sling Mindset
Everything as content
Discussion post, User profile information, etc.
Components put Content into JCR Content store
Sakai Kernel creates relational indices in DB
Component doesn’t need to do anything
Automatic tracking of most events by kernel
Philosophy similar to CouchDB
Will require developer education

JSON
Sakai Kernel supports JSON microformat
Components use REST calls to interact with Kernel
Benefits
Back-end services stay Java-based
UX programmers more often skilled in JavaScript
Easier UX developers can work on Sakai
Tools like GWT can be used for Java-based UI
Components can be written using other languages

Sakai 2.8?

Adopting Sakai
Adopt 2 or 3?
Not the first question to answer
First Question:
Yes! Or probably
Do you want to be using Sakai (and be in the community) in the long run?
We can help you figure out how to get there

Path to Sakai
Straight to 3? Start with 2?
It Depends!
What did you expect?
On what?
Your production timeline
Your appetite for “.0” software
Your functional needs
Your support model

Adopting 2 or 3?
Sakai 2.6 or 2.7
Sakai 2 works well today
3 doesn’t exist yet
Sakai 2 will be a good path to Sakai 3
Bb/WebCT migration to 2 is well known
Many will be migrating from Sakai 2 to 3
Straight to Sakai 3
You don’t have a CMS or you are using something like SharePoint
Your production timeline is 2012 or later
You have a very strong preference for Sakai 3

Adopting 2 or 3?
Maybe the wrong question
Adopt both!
Hybrid mode
Sakai 2 for courses, Sakai 3 for project collaboration
Gradually move users to Sakai 3
