I find LOD to be an extremely good idea. Moreover, I found even when I had attended lectures, sometimes I had missed details, as I may have been busy taking notes to listen effectively. Please continue to expand this service to reach more courses, as I have found it has greatly enhanced my ability to learn and understand the subject material. I am also studying engineering alongside commerce, and I feel that my learning in engineering courses would benefit from the LOD, as much of the subject material is quite difficult, and being able to listen to lectures on repeated occasions would definitely be of aid. Great way to catch up on missed lectures, without the hassle of having to borrow tapes from the library.
Biggest advantage is probably the ability to access the service from home.
This is a wonderful service, and invaluable to me personally as I have a lecture clash with this subject. I'm an Honours student in Economics. I just happened to stumble across this as I was browsing around. Keep up the great ideas. The University of Melbourne 1994-2000.
