Girls in Maths and Science

In a piece on a new OECD study in The Guardian it is noted that

school performance could be boosted by parents encouraging girls to consider careers involving subjects such as engineering

and quoting the report directly:

“Gender disparities in performance do not stem from innate differences in aptitude, but rather from students’ attitudes towards learning and their behaviour in school, from how they choose to spend their leisure time, and from the confidence they have,” the report said.

That quote gets, I think, closer to what’s actually going on. It also identifies that girls actually score higher on maths and science, yet fewer continue with it in the senior high school years, and study a STEM subject in university.

Indeed, parents and schools have an important role to play. From my own observations, lots of kids have an interest and potential for STEM topics, and the key is to enable and feed that interest and not sabotage it with unfortunate stereotyped remarks and many other unhelpful little things (that affect confidence).

You get the odd argument that maths & science are not cool. Well, kids these days play with all the cool technology, right? There’s the Internet, online games, tablets, and so on – and 3D printing, robotics, and much more. It would be rather odd to say that those things are cool, but the people who research and develop these things are not…

I think the issue with that originates with an idea that exists in some schools that it’s (for instance) science vs sports, and that does help us in exploring as to what’s going on there. With sport, you can see very directly what benefit kids get out of it, what they learn is directly applied and visible.

Often, STEM subjects are taught in a dry fashion, and kids indeed wonder what use it is learning all that stuff. We do appreciate that it’s a challenge for teachers to deliver an interesting program (let alone hands-on) program if the resources aren’t there to support it. This is of course even more problematic for kinaesthetic learners.

This is why we develop materials and programs for STEM subjects. With the use intrinsic to the process, kids want to explore more! Girls as well as boys.

Awesome Chemistry: Volcano Squid

Burning NH4Cr2O7 with HgSCN. Nicknamed “lucifer’s squid” this experiment is actually two reactions taking place:

  1. the decomposition of ammonium dichromate which results in the jet black volcano.
  2. The second is the combustion of mercury (II) thiocyanate, which causes the enormous “tentacles” to appear from within the mound.

By the sound of the kids in the background, the video appears to have been made in Slavic language country. It’s funny to hear them exclaim the word “Kraken” when the tentacle-like structures erupt (Dr Seuss mentions a Kraken in “Oh the Places You’ll Go”).

Open Source Earth Wind Patterns & Cyclone Marcia

Cameron Beccario created a beautiful live visualisation of the Earth’s wind, ocean and other weather patterns, using publicly available data. The full source code is all available at via Github – so a school could set up their own server for this and do all kinds of funky work!

Live site is up at earth.nullschool.net – the link will get you zoomed in to Australia but you can pan and zoom to anywhere you like!

cyclone-marcia-lam-earth-nullschoolAs I write this post you can see Cyclone Marcia (category 5) coming into the Central Queensland coast, and also Cyclone Lam east of Darwin in the Northern Territory. I took a snapshot which you can see above, but the live site is even prettier with the motion.

 

 

Google boss warns of ‘forgotten century’ with email and photos at risk | The Guardian

Digital material including key historical documents could be lost forever because programs to view them will become defunct, says Vint Cerf.

Inventing new technology is only half the battle, though. More difficult still could be navigating the legal permissions to copy and store software before it dies. When IT companies go out of business, or stop supporting their products, they may sell the rights on, making it a nightmarish task to get approval.

“To do this properly, the rights of preservation might need to be incorporated into our thinking about things like copyright and patents and licensing. We’re talking about preserving them for hundreds to thousands of years,” said Cerf.
