1. Content Partners Offer Users Unique Learning Tools
----------------------------------------------------------------
MIT OpenCourseWare (MIT OCW) has several
content partners who are providing users translations of MIT OCW courses and
other tools to improve their learning experience.
Open Learning Support (OLS)
is a joint MIT OCW/ Utah State University research project focused on building
"social software" that enables informal learning communities to form around
existing open educational content. The fundamental premise of OLS is that full
educational opportunity requires a user to have social access to other human
beings who can answer questions and provide support.
2. Foundations, Donors Fuel MIT OCW Success
----------------------------------------------------------------
MIT OCW would not be possible with the generous financial support of the
Hewlett and the Mellon Foundations, in addition to several MIT alumni who have
made financial donations to help us publish 915 courses.
The
Willam and Flora Hewlett
Foundation has generously supported MIT OCW financially through the initial
pilot phase and continues to to provide funding as MIT OCW works toward full
publication of all of MIT's courses. Headquartered in Menlo Park, CA, the
foundation concentrates its resources on activities in conflict resolution,
education, environment, performing arts, population, and U.S.-Latin American
relations.
MIT OCW has also received wonderful financial support from the
Andrew W. Mellon Foundation. The New York,
NY-based foundation is active in higher education, museums and art conservation,
performing arts, population, conservation and the environment, and public
affairs, and is committed to the concept of open sharing of educational
resources and tools, such as MIT OCW.
In addition,
MIT alumnus Jon
Gruber has donated $1 million to the MIT OCW project. Gruber's gift will
support the development and open publication of course materials in the
Department
of Electrical Engineering and Computer Science - his undergraduate
major - and also in MIT's various programs in the visual arts. Voluntary
donations by MIT alumni and our users is a wonderful endorsement of what this
project hopes to achieve long-term - promoting open sharing of information and
knowledge that will democratize information and make the world a better place.
If you choose to support MIT OCW financially, please make your check payable to
"MIT" and enclose a note indicating that the contribution is for the
OpenCourseWare Fund, #4021100. You can mail your check to:
Recording Secretary
MIT Office of the Treasurer

3. Digging Deeper: Course 3.46
----------------------------------------------------------------
There are currently
36
courses from MIT's DMSE available on MIT OCW, including this month's
featured course, Professor Lionel Kimerling's
Course
3.46 - Photonic Materials and Devices, Spring 2004, which explores
covers the theory, design, fabrication and applications of photonic materials
and devices. After a survey of optical materials design for semiconductors,
dielectrics and polymers, the course examines ray optics,
electromagnetic optics and guided wave optics; physics of light-matter
interactions; and device design principles of LEDs, lasers, photodetectors,
modulators, fiber and waveguide interconnects, optical filters, and photonic
crystals. Device processing topics include crystal growth, substrate
engineering, thin film deposition, etching and process integration for
dielectric, silicon and compound semiconductor materials.
Course 3.46 also offers a rich set of
Problem
Sets, and
six
past quizzes along with a final exam, featuring such mind-benders as the
following question: "Explain the differences in the gain spectrum between a
double heterostructure laser and a quantum well laser. Which is more desirable
and why?" Whew! Let the self-learning begin!
The course also offers a
guide
to the design process, including four sample design reviews, and a sample of
Professor Kimerling's comments on the design review process.
4. A Frequently Asked Question
----------------------------------------------------------------
QUESTION: Can I download MIT OCW videos to my computer for viewing
off-line?
ANSWER: Most of the video that MIT OCW provides is in a Real Video format
delivered through streaming servers. Our goal in providing video in this format
(in multiple bitrates) is to enable users with a variety of Internet connections
to sample MIT OCW video offerings with a common browser plug-in without having
to download large media files. Users are able to download our streaming video
file if you prefer to play these files off-line. There are two typical URL
structures for links to MIT OCW video lecture delivered in a streaming
format:
- OCW video files stored on the Akamai network will have URLs that look
something like this
http://mfile.akamai.com/7870/rm/mitstorage.download.akamai.com/7870/18/18.06/videolectures/strang-1806-lec01-26aug1999-220k.rm
If you want to download this file and play it off-line, use the following URL
-- the only difference is in the first part of the URL:
http://ocw.mit.edu/ans7870/18/18.06/videolectures/strang-1806-lec01-26aug1999-220k.rm
- This same basic approach will work for all of the MIT OCW streaming videos
stored on the Akamai network. Simply find the URL to the streaming media, and
replace the first part of the URL
http://mfile.akamai.com/7870/rm/mitstorage.download.akamai.com/7870 with
http://ocw.mit.edu/ans7870
- OCW video files stored on the Internet Archive (such as those for "Course
18.03 -- Differential Equations, Spring 2004") will have URLs that look
something like this:
http://www.archive.org/stream/mitocw.18.03.f03.videolectures/mit-ocw-18.03-lec1-05feb2003-220k.rm
- To download this file and play it off-line, use the following URL -- the
only difference is that you replace "stream" with "download":
http://www.archive.org/download/mitocw.18.03.f03.videolectures/mit-ocw-18.03-lec1-05feb2003-220k.rm
This same basic approach will work for all the MIT OCW streaming videos
stored on the Internet Archive network. Simply find the URL to the streaming
media file and replace the word "stream" with the word "download."

MIT OpenCourseWare (MIT OCW) is a
large-scale, Web-based publishing initiative with the goal of providing free,
searchable access to MIT course materials for educators, students, and
individual learners around the world. These materials are offered in a single,
searchable structure spanning all of MIT's academic disciplines, and include
uniform metadata about the contents of the individual subject sites.
