Computers in classrooms: a waste of money?

While the findings are quite complex, the take-out message from a recent OECD study is:

    On average, in the past 10 years there has been no appreciable improvement in student achievement in reading, mathematics or science in the countries that have invested heavily in information and communication technologies for education.

Innovation and economic complexity

Goran Roos, Adjunct professor at University of Technology Sydney, explains why advanced manufacturing is an essential feature of ‘economic complexity’ and that “a nation’s potential to create prosperity is a direct function of its economic complexity.”

Australia’s economic complexity has declined over the last 25 years, to the point where it ranked 53 among all countries in 2012. The top three were Japan, Switzerland and Sweden. Losing the car industry is likely to lower Australia’s economic complexity by a further 5-15%. The share of manufacturing in Australia’s economy is likely to be below 5%, compared to Switzerland’s 20%. Continue reading Innovation and economic complexity

Should Bill Shorten give up?

Newspoll has the LNP on a comfortable lead of 52-48 on TPP terms. Last week Fairfax-Ipsos came in at 53-47, which is landslide territory.

Back in Oz

Away for 35 days, it was really five holidays in a row – Berlin, Erlangen, Prague, Poland and the boat trip from Passau to Budapest. The overall impression is of 500 million people on the move. A surprising number of people we met had connections with Australia, but if we dropped off the map, I think the world would just blink and carry on.

One way of judging Europe is by their cars. They drive better cars than we do, and that includes Poland and the central European countries. No bombs or rust buckets on the road. Did you know that Slovakia with a population of 5.4 million makes over a million cars per annum? Continue reading Back in Oz

1. Turnbull’s ascension

Abbott’s fall and Turnbull’s ascension was the first news we got from home, via a text from our son.

I must admit I didn’t see it coming. I’d written Turnbull off as unacceptable to the Liberal Party. Now suddenly he’s there and Shorten looks like a dead man walking.

Mark has a piece in the Guardian. Continue reading Saturday salon 17/10: late edition
