in its core distribution, that

I would get a Blackboard

• Sample Java + PHP Basic LTI implementations at

• http://code.google.com/p/ims-dev/

• Use/include sample code from oauth.net

• Structured to provide reusable code

• org.imsglobalorg.basiclti.BasicLTIUtil.java

• blti_util.php

• Copyright IMS, Apache 2 – Usable anywhere


25

Sample Code – Apache 2.0

• Simple PHP application

• GregsList PHP application (PHP)

• Java Filter

• AppEngine Python Appication

• AppEngine Java Application

• IMS Certification Suite (PHP)


26

Classified Ad Application

• Simple Sample Application

Basic LTI and IMS Common Cartridge 1.1

• Common Cartridge 1.1 will

include 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 centrally hosted content.

Engaging open source, creating standards, engaging proprietary vendors, promoting ideas, giving lectures, doing demonstrations, getting tattoos, all are important activities...


32

The real reason for this activity is to empower teachers and learners as to how they select and use tools and content to help themselves teach and learn...


33

Looking Ahead....


34

Pain Points

• Educators– Find , Select and Sequence Educational Apps

– Collect progress and results from multiple sources

• Students– single starting point, integrated progress reporting

• App Providers– Provision User Profiles

– Reporting Data to existing Learning Management Systems

How this will likely play out...

• Ecommerce model – store takes a cut

• Branded App Stores like Blackboard, Pearson,

McGraw-Hill

• "Public good" app stores like IMS or MERLOT

• Independent high value store from a startup


39

How this will likely play out...

• Competition will be the store that has the best

stuff and reputation

• There will be more than one of these stores

• It is nice that the protocol (Basic LTI) is a

standard before the first store exists because it

might make it so you can write one tool and put

it in all the stores
