Case Study: Amanda Severance

• Senior in Special Education

• Technology in the

Classroom Course

• Eleven different accounts

• Setup required technical

support

Too Many LMS Extension Points

• Blackboard Building Blocks

• Moodle Modules

• Sakai Tools

• WebCT PowerLinks

• ....

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

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

Again in slow motion…

Tool looks up secret and validates signature.

Tool provisions user, course, and session.

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

• The LMS supports LTI.

• They could add a link from

their LMS to an LMS in the

cloud that they actually like

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

Returning Grades (LTI 1.1)

Service Patterns in Transition

• Legacy: RPC-Style Services with SOAP/WSDL

• Transition: RPC-Style Services with

XML/OAuth

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*)

* in progress

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

JSON-LD – www.json-ld.org

• RDF / Linked-Data meets Hacker-Friendly

• Depending on the applicatio, you can look at

it as triples or just a clean serialization of a

REST-Style resource

{ "@context" : "http://purl.org/ims/lti/v1/jsonld/ToolProxy", "@subject" : "urn:lti:ToolConsumerProfile:alpha.university.edu", "product_instance" : { }, "service_offered" : [ ], "capability" : [ "Person.name.given", "Person.name.family", "Person.email.primary", "User.image" "Result.sourcedGUID", "basic-lti-launch-request", "ToolProxyReregisterRequest", "LineItem.autocreate", "Result.autocreate" ]}

• 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

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

Summary

• IMS Learning Tools Interoperability 1.0 (Basic

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
