If the SMH can’t get it right, who can?

Floundering in a sea of change: I still consider the New York Times to be the pinnacle of journalism, but is it floundering because of the collapse of the old guard, and “the cost structures and privileges of the old media are being swept away”?

‘Human flesh search engine’ in hot pursuit of the iPhone girl, proclaims the headline. I was initially quite curious as to why there is a search engine that indexes bits of human flesh on the planet. Update: Tommy suggests that the phrase “human flesh search engine” is a literal translation from the Chinese.

News round-up

The SMH carried an interesting opinion piece today about the changes happening to Sydney Uni under the campus 2010 project — I honestly didn’t expect to see anything like that in the Herald because this is more the purview of a communist campus newspaper with nothing better to talk about. That aside, I don’t quite agree with the author’s viewpoint. The main point of contention is that Sydney Uni lost something valuable in its recent construction frenzy. Let’s examine that a little closer. To build the School of Information Technologies building (which I’m very happy to use), we lost a small lawn. Stephen Roberts lecture theatre, which was razed to give way to the Great Law Faculty Ditch, was hardly a work of art. And I’m sure no one will miss the tin sheds that once stood where the USyd Central building is now being erected. I suppose we might miss the trees on Eastern Avenue, but I sure won’t miss the cars — the pedestrianisation of that part of campus could only encourage a larger number of activities on the shiny new pavement. If anything, the modernisation of main campus adds value instead of taking it away, because you can have first class facilities and sip your latte in the shadows of a sandstone archway. Although it could be seen as copying other universities, the truth of the matter is that each major period of development has left its own particular style on the campus, and this major revamp is no different.

In other news, it has been 10 years since Hong Kong reverted to Chinese sovereignty. It’s a bit of a pet subject for me, and the Economist ran a special report on the past, the present and the future. Basically, it argued that Hong Kong deserves democracy along with its other freedoms, partly to stop its freedoms from getting whittled away, and that China lost a potential experiment in democracy. That’s all nice and good, but it’s wishful thinking and commentary on how to make the best of the situation would’ve been more productive.

The University of Sydney Faculty of Law recently passed a series of changes to the teaching of undergraduate courses. The changes are outlined in SULS’ email (reposted on their web site), and the SMH published an article about it together with comments from student representatives. Personally, I don’t place too much weight on the comments in the article, because it’s the kind of kerfuffle student politicians love to stir up.

In summary, the contentious changes are:

  • A reduction in teaching load of academics by 25%
  • An increase in average class size from 40 to 70

I must admit that my initial response to the news of the changes was that of astonishment and disbelief - disbelief that my return to law school next year will be potentially made even more unpalatable. From the response so far, I think I can say with some confidence that a large proportion of the law student population, on hearing of the changes, had similar thoughts. Indeed, this had me thinking about whether I should continue on to law school after honours after all; a transfer to UNSW does already have its attractions, such as its pretty new law building.

A key attraction of the Sydney Law School has been its claim of “small group teaching”, which was pioneered by UNSW Law School (which has had this mode of teaching from its the very beginning). Indeed, with current average class sizes of 40, this is comparable to the average UNSW class size.

The supposed attraction of small group teaching is that it allows for greater interaction between the lecturer and the students, where the lesson becomes interactive, a two-way street. However, from experience, the beneficiaries of this system are a minority (unfortunately). Even with the incentive provided by class participation marks, the proportion of students who actively interact with the discussion at hand is typically small. Furthermore, there is no getting away from basic lecturing - sure, a large part of the material is delivered via the readings, but a good lecturer will reinforce the readings by covering them in class as well; repeated over a number of small classes, this is inefficient.

The increase in average class sizes does not necessarily mean a significant loss of “air time” for students. No sane lecturer would bother holding discussions in a room with 70 people. The increase in efficiency of delivery of lecture-type material possibly even counteracts the reduction in total class time. As the experience with the revamped second-year contracts course demonstrates, an average class size of 70 does not mean that all classes will have 70 students in them (the average law student has a poor grasp of statistics principles, I fear). In contracts, as I was told today, they have lectures of over 100 students (filling a Carslaw lecture theatre) and seminars of 10 students, where they work through problems. This is precisely the enactment of what I discussed above - by removing the inefficiency of repeating lecture material, the small group teaching component is allowed to flourish.

As another friend pointed out, the declaration by the faculty would not mean an immediate change - because there are only a few rooms at the law building that can facilitate lectures of 70 students. The resolution probably had the move to main campus in mind, where finding such teaching space is less of a problem.

Just keep in mind that I’m not saying that I agree in full, or even in part, with the changes. All I’m arguing is that the changes do not necessarily mean hell on earth for law students at the university, or at least a reduction in teaching quality. There may be well-founded reasons, and even if there aren’t well-founded reasons, the changes do not necessarily have an effect on learning either. I don’t claim to know more about the situation than anyone else, and as the Dean wrote in his terse letter back to SULS, don’t make such a big fuss out of it if you don’t know the full story - speaking of which, perhaps SULS could learn from their own handbook about how to do well in negotiations.

The SMH article “Rolling hotspots take villages online” described a system in which buses with Wi-Fi visited villages several times a day to deliver Internet access, in areas of developing countries where it would be uneconomical to service with fixed line services. How it seems to work is that requests (clicks on a page, outgoing emails) are stored and then the response is delivered next time the bus comes along. This reminded me of the work being done to rework networking protocols for use in outer space, where the store-and-forward technique is required to cope with the long delays between hops, and the possibility that a line of sight connection is not always available. I haven’t looked into the technology behind the Wi-Fi buses, but if they somehow made existing Internet protocols reliably delay-tolerant, that is some feat.
