Impact Well-Beyond Market Share: Synergy Between Open Source and Standards
0 likes515 views
This document summarizes Dr. Charles Severance's work over 20 years to promote open standards and interoperability between learning tools and systems. It shows his involvement in early online learning projects in the 1990s, the development of the Learning Tools Interoperability specification in the 2000s, and his role in evangelizing Simple LTI and Basic LTI to achieve widespread adoption across both open source and proprietary learning platforms by 2010. The overarching goal was to empower teachers and learners by giving them more choice and control over the tools and technologies used for teaching and learning.

- 2. A Quest... Fighting to empower teachers and learners to have a wide range of tools and technologies to use in teaching and learning without waiting for a vendor or their campus IT deparement to "get around to it". In a sense I want an "App Store" for software to support teaching and learning.

- 37. Learning Tools Interoperability • Wimba and Microsoft were leading the Learning Tools Interoperability Working Group • The specification was well along - closely mirrored Wimba's cross-LMS integration approach • Wimba had hired a staff member who built a reference implementation of the draft specification • I was planning a Google Summer of Code Effort to implement the specification in Sakai (both code and PR) February 2008
- 38. Blackboard and Pearson • Blackboard approached us and offered us the IP for their upcoming "Proxy Tool" which was to be part of the Blackboard 9 release • It was more robust than the Wimba approach and lining up with the market leader (and Wimba's largest partner) seemed wise • The staff person from Wimba nearly quit and Wimba slowly reduced its leadership and suport - Blackboard and Pearson took over the working group • From a maturity perspective, it was "back to the drawing board" March 2008
- 39. Enter "Simple LTI" • I had a Google Summer of Code in-flight for Sakai and Moodle • So I invented a non-specification that was a bit of Wimba and a bit of Blackboard - I called it Simple LTI and promised it would be "temp" • Marc Alier (Moodle committer) made the "Dinosaur Video" • http://www.vimeo.com/7825070 March 2008 - July 2008
- 41. Educause 2008 • Microsoft put up funds to build an open-source reference implementation of IMS Common Cartridge and Simple LTI • www.mirlearn.com • IMS Common Cartridge + Simple LTI Demonstration at Educause • LMS: "Microsoft" and Angel • Content: Pearson and McGraw-Hill November 2008
- 43. Basic LTI is "Almost Ready" • Learning Tools Interoperability had progressed nicely under the leadership of Blackboard and Pearson • We decided to build "Basic LTI" which has the scope of Simple LTI but perfectly aligned with LTI • IMS funds a reference implementation of Basic LTI in Java and PHP • Work on Sakai support for Basic LTI begins using the reference implementation - In production at UMich January 2009 December 2008
- 44. Summer Fun 2009 • Blackboard purchases Angel May 2009 • Steven Vickers, of Edinubrgh builds open source Basic LTI Building Block for Blackboard and PowerLink forWebCT - with assistance and support from Blacboard • Work begins on a Moodle 1.9 module for Basic LTI June 2009
- 46. Educause 2009 • We have working Basic LTI for Sakai, Blackboard, and WebCT and do a number of demos including one at the Blackboard booth. • Desire2Learn ships Basic LTI in their 8.4.2 release as a patch and issues a press release October 2009
- 48. Closing In... • The LTI Working Group put the finishing touches on the Basic LTI specification and starts "Internal Draft Review" for all IMS Members • IMS funds the develoment of a Basic LTI certification test • Moodle 2.0 agrees to include Basic LTI out of the box • I visit Zurich and build a Basic LTI tool and contribute it to OLAT • Penn State University Starts work on open source Angel Nugget March 2010
- 50. May 2010
- 51. What's Next? • Promote Basic LTI to Tool Writers • http://videos.noteflight.com/ MoodleBasicLTI.mov • Get Moodle 2.0 shipped with Basic LTI • Encourage Blackboard to include Basic LTI in a release
- 52. Enagaging open source, standards, engaging propretary vendors, evanglizing ideas, all are important activities... my long-term goal is to empower teachers and learners as to how they select and use technology to help themselves teach and learn...
- 53. My technical objective is to make it so that teachers can easily trade software and content between each other (like virtual baseball cards). Regardless of what learning management system (or systems) their institution has adopted.
