MIT OpenCourseWareA New Model for Open Sharing

Open Content

“OpenCourseWare looks counter-intuitive in a market-driven world. It goes against the grain of current material values. But it really is consistent with what I believe is the best about MIT. It is innovative. It expresses our belief in the way education can be advanced – by constantly widening access to information and by inspiring others to participate.”

– Charles M. Vest,President of MIT

• Fall 1999 — Faculty committee appointed

• Fall 2000 — “OpenCourseWare” concept recommended to MIT President Charles M. Vest

• April 2001 — MIT OCW announced in The New York Times

• June 2001 — Funding partnership with the William and Flora Hewlett Foundation, and the Andrew W. Mellon Foundation

• September 2002 — MIT OCW Pilot site opened to the public50 courses from 23 academic disciplines

• September 2003 — MIT OCW officially launched: 500 courses from all five MIT schools and 33 academic

disciplines

• April 2004 — 200 additional courses, bringing total to 701

Vision to RealityHow Should MIT respond to the Opportunities of the Internet?

• An MIT education

• Intended to represent or replace the interactive classroom environment

• A distance education initiative

• A Web-based publication of virtually all MIT course content

• Open and available to the world

• A permanent MIT activity

MIT OpenCourseWare IS NOT:

MIT OpenCourseWare IS:

What Is MIT OCW?

• Provide free, searchable, coherent access to all MIT course materials for educators, students, and individual learners around the world

• Create an efficient, standards-based model that other educational institutions may use to publish their own course materials

Dual Mission: Open Content

• Furthers MIT’s fundamental mission

• Embraces faculty values

• Teaching• Sharing best practices with the greater

community• Contributing to their discipline

• Counters the privatization of knowledge and champions the movement toward greater openness

• Other OCWs are beginning to appear

• Some using MIT materials, some using the format, some using the idea

Impact: Emerging “opencoursewares”

• Continues to be tremendous excitement

• The vision is achievable

• The impact of MIT OCW will be significant

Open specifications that

leading to…

Architectural Specification Benefits

Ability of learning technologies to be integrated together into an educational infrastructure.

Easier sharing of applications and content among institutions that can be a catalyst for cooperative and commercial development.

Lower long term cost of software ownership, as well as increased stability and reliability because single components, rather than entire systems, can be replaced or upgraded.

Infrastructure Goals

Linkage and Coherence across initiatives Managing the Educational Content Lifecycle from

Acquisition to Archiving Efficiency in Production and Use Effectiveness for educational use

Interoperable with Campus Infrastructures and other Educational Software

Flexible to meet a variety of Educational Needs Sustainability
