The informationarchitecture for

IMS Learning InformationServices (LIS)

** Acute Pain Points **• Separate accounts for all every service

• It is not legal to force student learning activity to be

public

• Little tool interest in integrating tools into LMS's

• Usually very expensive even to start

• Very complex – moving target technically

• Every LMS vendor is *completely* different

Case Study: Amanda Severance

• Senior in Special Education

• Technology in the

Classroom Course

• Eleven different accounts

• Setup required technical

Solution: Basic Learning Tools Interoperability

• Build a simple standard plug-in for all LMS

systems

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

• Start with low-hanging fruit and then expand feature sets to allow market to acclimate over time

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)

BLTI Extensions Pattern

• 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

Engaging open source, creating standards, engaging proprietary vendors, evangelizing ideas, doing demos, all are important activities...

But if we want to have have real impact, the long-term goal must be to empower teachers and learners as to how they select, use and expand, technology to help themselves teach and learn...
