IMS Basic Learning ToolsInteroperability


2

Learning Tools Interoperability

• Problem

• Every CMS has their own very unique "module",

"tool" "block", "nugget", "powerlink", etc

• External tools like QuestionMark, Wimba,

Elluminate, etc must prioritize which CMS they

invest in plugging into

• Tool Providers wait until customers are willing to

pay money to start development


3

Case Study: Amanda Severance

• Senior in Special Education

• Technology in the

Classroom Course

• Eleven different accounts

• Setup required technical

support


4


• Solution• Build a standard plug-in for all CMS systems

• Tool and Content Providers can build one integration and use it in any CMS that supports the standard

• Start simple and basic and then expand feature sets to allow market to adjust over time and insure that engineering due diligence is being done – phased release

LTI Terminology

• Tool Consumer – The system that

"consumes" the tool (i.e. the Learning

Management System – e.g. Blackboard,

Moodle)

• Tool Provider – The system that provides the

tool (e.g. Wimba, LearningObjects, etc..)

Basic LTI Goals

• We decided to roll out Learning Tools

Interoperability in a phased series of releases

• These specifications are pretty detailed so we

want to get them right

• We want to engineer reference implementations

along the way

• Basic LTI: "The smallest useful subset of LTI"

Basic LTI Certification

• Assure the end-user/purchaser that products will

interoperate

• Any certified Provider (Tool) should be able to

interoperate with any certified Consumer (LMS)

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.

Basic LTI and IMS Common Cartridge

• Common Cartridge 1.1 will

include the ability to define

a Basic LTI resource and

include that resource in

course organizational

structures

38

BLTI Outcome Extension

• Add fields to launch

• lis_result_sourcedid – represents course,

resource, gradebook, user in one id – opaque to

tool

• ext_ims_lis_simple_outcome_url – Service URL

• ext_ims_lis_resultvalue_sourcedids – a list of

types of outcomes accepted (decimal,

percentage, passfail ..)


39

BLTI Outcome Extension

• Service can be called any time (i.e. no session

needed)

• Tool sends outcome to service as form-encoded

POST data, signed by OAuth shared-secret

• lis_result_sourcedid is separately signed by

the LMS which checks signature upon receipt
