No More "Basic" or "Full"

• Strong directive from the IMS Board

• CALL IT "LTI"!

• ADD GRADES!

• PUBLISH IT YESTERDAY!

• Will be a gradual roll out of functionality as

the market can absorb it


9

Phased Roll Out

• LTI 1.0 – May 2010• Basic Tool Launch and Common Cartridge 1.1

• LTI 1.1 – 4Q2011• Return Grades back to the LMS

• LTI 2.0 – In Progress• Automatic provisioning of URL, Key, Secret• Expanded Outcome Handling Service• Deeper Cartridge Interactions – Abstraction layer

LMS Looks up User and Course Information.

Information is signed using secret and OAuth

Form data sent to Browser

Again in slow motion…

<form action=”tool”/><input name=”user_id” value=”2348d8dd” /><input name=”oauth_token” value=”abc.edu” /></form>

Tool looks up secret and validates signature.

Tool provisions user, course, and session.

Tool sends redirect

Form is immediately auto-submitted using JavaScript.

<head><meta redirect page=”main.php”></head>

Tool produces first page.

Browser follows redirect…

Purpose of Certification

• Assure the end-user/purchaser that products will

interoperate

• Any certified Provider (Tool) should be able to

interoperate with any certified Consumer (LMS)

IDEA: LMS As Tool Provider..

• Imagine a teacher at a school

and they do not like their

LMS.

• The LMS supports LTI.

• They could add a link from

their LMS to an LMS in the

cloud that they actually like


27

LMS as Tool Provider

• Sakai 2.8• Exports Tool Instances

• Trusted Mode: OAE Hybrid or Portal / CLE

• Moodle 2.x Module – Juan Levya • Exports Course or Tool

• Can use to merge students into instance

• Blackboard 9.1– Prototype Building Block

Service Patterns in Transition

• Legacy: RPC-Style Services with SOAP/WSDL

• Transition: RPC-Style Services with

XML/OAuth

• Next Generation: Resource Style Services /

REST

35

LTI 1.0 (Basic) and IMS Common Cartridge 1.1

• Common Cartridge 1.1

includes the ability to

define a Basic LTI resource

and include that resource

in course organizational

structures

When LTI is combined with the IMS Common Cartridge 1.1, publishers can distribute cartridges containing active, authenticated links back to centrally hosted content.

Certified – CC

• Blackboard (1.0, 1.1, import and export)

• Desire2Learn (1.0, 1.1*)

• Jenzabar e-Racer (1.0, 1.1*)

• Atutor (1.0, 1.1*)

• Moodle 1.9 (1.0*) 2.0 (1.0*, 1.1*)

• Sakai 2.9 (1.0*, 1.1*)

39

IMS LTI 2.0

• Transition to resource oriented models for

services with RDF/REST Bindings

• Tool registration – Great increase in convenience

and support for App Store use cases

• Richer grade exchange services

• Improved abstraction in representing tools in

cartridges


40

JSON-LD – www.json-ld.org

• RDF / Linked-Data meets Hacker-Friendly

JSON

• Depending on the applicatio, you can look at

it as triples or just a clean serialization of a

REST-Style resource

2.0

• Tool Registration – Key / Secret Web Services

• Much Broader Grade Services

• Better Common Cartridge

• Two layers of abstraction

Developer Support from IMS

• Test Harnesses

• Sample Code

• Recorded Presentations

• Certification

• Staff help for IMS Members

A Crazy Idea called "Tsugi"

• Learning Tool Building Kit

in PHP – Moodle-like

• An empty LMS with

support code and services

• IMS Standards in library

code

Some Tsugi Tool Ideas...

• Seating Chart

• Drop Box

• To-Do List

• Comments

• Attendance taker

• Certificates / Badges

• Booking

appointment/office

hour slots

• Doodle Integration

• Progress Markers

• Mini-assessments

Launch) is well adopted by LMS and Tool

vendors

• IMS CC 1.0 and 1.1 are appearing everywhere

• IMS Learning Tools Interoperability 1.1 adds

grade return

• IMS LTI 2.0
