Well, this is the 6th day of teaching and the first day of the second week. (I’m not counting weekends.) Some of the students went to Shenzen over the weekend and discovered “an electronics mall the size of Adelaide” which was the big motivator for going. Sadly, I wasn’t able to join them at the World Cup this morning as my flight got in late and I still had marking and work to do, but here’s a picture that one of the students, Sarah, took of the crowd – and they were a very vocal crowd for 3 in the morning!
Today we finished off talking about the way that programmers work with the network when they write applications. When someone sends information too fast for a receiver, we need to control the flow of the information, but when there’s just too much information on the network (from possibly many sources) we have to deal with the congestion. Both of these (and the solutions we use) are really important reasons why the Internet works today! We had a lot of discussion, group-based work and I spent a lot of whiteboard time motivating how we could get information out of the network without having to do anything beyond what we already wanted to do, just to use it.
We had started later so students could get some downtime and it certainly paid off because participation was as good as it had been on other days and brains were only slightly slower than usual. It’s the great thing about having the freedom we have here, teaching only one course and leaving time for work and thinking time. I certainly prefer it as a teaching approach!
Feedback on the quiz and short exam are also positive although there is work to do on making the questions slightly less ambiguous because the terminology of networking often coincides with other uses and there isn’t the same amount of time to get students used to a new reference frame.
After a steamy few days, it seems cooler today and we’re seeing a large amount of blue sky. Here’s what the campus looks like from outside the building I’m teaching in!

Well, we had a normal session to start with, which consisted of discussion about the Transport layer (that bit of the network that makes it easier for the people who program your web browser to talk a web server) and some of it was good but some of it – ehhh, I think it got away from me. There are some really complicated diagrams and I’m still thinking about the best way to teach them. I suspect it’s something you go away and do, then discuss, then do again so that’s a note to self.
We broke for lunch and I (coincidentally) ended up at the same place as my students so I joined them. (There is no escaping the Nick.) They’re all doing the right thing and eating everywhere to see what’s good and basically getting into the whole experience. (They may all be addicted to duck’s web now. Sorry, that’s my fault.)
After lunch, it was short quiz and short exam time – the students have weekly quizzes, marked automatically and worth 5% each, and then a short answer exam, which I mark manually and these are worth 10% each. Because of the compressed timescale, I’m trying to scaffold the revision process by requiring the knowledge earlier. From what I’ve seen so far, it appears to be working, although I’m not sure how appreciative the students are. Once I’ve marked everything, I’ll discuss it with them to see what their impressions are. I’m a great believer in working with students to try and build better courses and this is one of the best opportunities I’ll ever have.
I have to head back to Australia for the weekend but I’ll be back Sunday afternoon. Until then I’ve asked my students to work hard, play hard and be safe. I’ve delayed the class on Monday morning from 9am to 1pm, not because I’ll be jet lagged, but because CUHK is putting on a giant screen showing of the world cup with local commentators, starting from 3am. This is exactly the kind of serendipitous cultural moment that we want to capture in these sorts of exchanges so, not only am I shifting the class, I’m planning to go along myself.
Sorry to my German readers but I have to support Argentina or my friend Guadalupe will kill me. Vamos Argentina! Have a great weekend and I’ll fill you in on Monday in a few days.
