What can you learn from Descartes?

By James Dacey in Córdoba, Argentina

What’s the best way to teach tricky physics concepts to students? Naturally, this was one of the questions underpinning many of the talks here at the International Conference of Physics Education (IPCE) in Córdoba. According to a couple of educationalists in Latin America at least, it seems that one approach is to enlist the help of some of the great scientists and philosophers of the past.

Patricia del V. Repossi, a lecturer at the Pontificia Universidad Católica Argentina in Buenos Aires, spoke about how she uses the history of science as a framework for teaching optics. Repossi explained how she had come to realize that some of the students taking her conventional optics course believed that photons are made of the same stuff as “tennis balls”. So, she and her colleagues set about transforming the way they teach the topic – by combining a physics class with a history lesson.

Thinking about thinking

By James Dacey in Córdoba, Argentina

There has been a lot of fancy language flying around here at the International Conference on Physics Education (ICPE), which is taking place in Córdoba. Words such as “pedagogy” and “metacognition” roll off the tongues of education researchers as naturally as a particle physicist at CERN saying the words “Higgs boson”.

At first it seemed a bit like a foreign language to me, but I’ve started to realize that one of the recurring ideas at the conference can be described in more everyday terms: thinking about thinking. Teachers should think about the way they think about learning, and the way their students think about learning.

Turning a physics class into a video game

By James Dacey in Córdoba, Argentina

“When was the last time you heard a student say they wanted a physics course that was long and difficult?”

That was a rhetorical question that physicist and education researcher Ian Beatty put to us today while delivering his keynote talk at the International Conference on Physics Education (ICPE) 2014 here in Argentina. Beatty’s point is that two of the worst things that people say about computer games is that they are too easy or that they end too quickly. Needless to say, he had never heard such protestations from his physics students!

Beatty, a physicist and educational researcher at the University of North Carolina at Greensboro in the US, believes that course creators could learn a trick or two from game designers. He has therefore spent the past three years trying to understand what it is about video games that makes them so appealing to gamers, and how to incorporate some of the underlying principles into a physics course.

Physics education under the microscope in Argentina

Local musicians in Argentina

A warm welcome from Argentina.

By James Dacey in Córdoba, Argentina

I’m writing this blog entry from the heart of Argentina, following a marathon 30-hour journey from my home in Bristol, UK. It was a trip that included two planes, a few buses, a couple of taxis and several long walks, but I’m finally here in Córdoba – Argentina’s second largest city – to attend this year’s International Conference on Physics Education (ICPE).

The meeting’s all about bringing together people to discuss the latest developments in education – including lecturers, teachers, trainers, students and educational researchers. It’s an event with a global outlook, accompanied by a satellite meeting where local high-school teachers will be discussing issues more focused on their day-to-day experiences. At the registration session, things already took a welcome Argentine twist as we were treated to a performance from some local musicians (see picture above).

Hello Kitty in space, Lord of the Rings physics homework and more

By Tushna Commissariat

This week, South Korea’s one and only astronaut, 36-year-old Yi So-yeon, has quit her job, thereby signalling the end of the country’s manned space programme for the time being. In 2008 Yi became the first Korean to go into space, when for 11 days she travelled on board a Russian Soyuz spacecraft to the International Space Station, after being chosen through the government-run Korean Astronaut Program. Yi cited personal reasons for quitting, but has been studying for an MBA in the US since 2012. You can read more about her work and reasons for leaving in articles from Australia Network News and abc News.

Choosing physics, or not

By Margaret Harris

I’ve been mulling over this topic for a while, but a pair of blog posts this week has finally prompted me to write about it. One of them, entitled “Why I won’t be studying physics at A-level” appeared yesterday in the education section of the Guardian newspaper. In it, the anonymous female author lists a number of reasons why she is leaving physics, including a lack of female teachers and an “uninspiring” GCSE physics syllabus that “seemed out of touch compared with the stem cells and glucoregulation we were studying in biology”. There’s plenty to debate there already, but to me, the following paragraph was the most striking:

“I don’t dislike physics; neither do I find it boring or particularly difficult. But I do enjoy my other subjects more, so when it came to choosing between physics and geography for my fourth AS-level I opted for the latter. I thought it would be good to take a humanities subject to balance out the sciences.”

Physics in the fast lane

By Matin Durrani

Most of us want everything in life right here, right now. From fast food to fast cars, none of us can be bothered to hang about any longer than absolutely necessary. Where’s your reply to my e-mail I sent five minutes ago? Why haven’t you responded to my Tweet? Do you really expect me to read that 500-page novel for fun?

It was perhaps as an antidote to the ever-faster pace of life that so much has been made of two physics experiments that recently produced new data for the first time in years. I’m talking, of course, about the “pitch-drop” experiments at Trinity College Dublin in Ireland and the University of Queensland, Australia, which both consist of a glass funnel of sticky tar-like substance. A drop from the Trinity experiment finally fell last July, with a video of the event quickly going viral, while the Queensland set-up dripped this April for the first time in 13 years. (For more on why both experiments proved so popular, check out our great feature by Shane D Bergin, Stefan Hutzler and Denis Weaire from Trinity.)

But if you can’t be bothered to hang around for 10 years or more, you’ll be pleased to hear that physicists at Queen Mary University of London – led by Kostya Trachenko – have now set up a new pitch-drop experiment to explore the difference between solid and liquids on the much shorter timescale of just a few months.

When waiting for 10 years is just too long

silly putty experiment

Fed up with waiting 10 years for a drip of pitch to fall? Try Silly Putty instead.

By Matin Durrani

In case you haven’t seen it yet, I do encourage you to read our feature article from the May issue of Physics World about the now-famous pitch-drop experiment at Trinity College Dublin. This simple funnel of pitch shot to fame last year after a drop from it was finally observed falling for the first time – with a video of the dripping drop having so far been viewed more than two million times on YouTube.

Although it was the first time that a drop had been seen to drip from the Dublin funnel, it’s thought that other drops would have fallen about once a decade since the apparatus was set up in 1944. Be that as it may, Trevor Cawthorne from Queen Elizabeth’s Grammar School in Horncastle, Lincolnshire, UK, e-mailed me this morning, pointing out – quite rightly – that “10 years is a long time to wait for the results of an experiment”.

Postcard from Rio – a paradise for physics?

By Matin Durrani in Rio de Janeiro

Having flown almost half-way round the world from Bristol to Rio, you might think there is little in common between Physics World‘s home city and the Brazilian metropolis.

But on my trip to the Brazilian Centre for Physics Research (CBPF) in Rio today, it soon became clear from the statistical physicist Constantino Tsallis, who hosted my visit, that there is indeed a link between the two cities. That connection lies with the Brazilian physicist César Lattes, who was the founding director of the CBPF.
