** 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

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...
