“Raw” water – an update - BioBlog

Alison Campbell Apr 26, 2019

In January last year, I wrote about the US fad for “raw” water: water supposedly as nature intended it, free of any of the treatments used in municipal water supplies. Those promoting the stuff claim it’s ever so much better for you; given the prices they charge, it’s certainly good for their bank balances I’ve just come across a … Read More

Human evolution and attention-grabbing headlines - BioBlog

Alison Campbell Jan 16, 2019

Every so often there’s a new story claiming that a study has overturned our understanding of human evolution. (Or something along those lines.) I’ve just come across another one**, & thought I’d write this post as a warning to year 13 biology students. As Carl Sagan once said, extraordinary claims require extraordinary evidence – something that’s lacking in this particular … Read More

Preparing for scholarship: critical thinking - BioBlog

Alison Campbell Jun 27, 2018

I met with a local biology teacher today to talk about setting up a Schol Bio preparation day in the Waikato, and we also discussed things like the need for critical thinking skills (in addition to a solid base of knowledge from students’ year 12 & year 13 studies and time spent in reading more widely around the subject). So … Read More

Appeal to antiquity? Appeal to nature? Bingo! - BioBlog

Alison Campbell Jun 13, 2018

I was idly skimming the Herald’s website when I came across an article with the headline “Is plant medicine really that effective?” Since the article appears to be in the nature of an advertorial, the answer is, it depends on who you ask. Unlike man-made chemical drugs that have been developed as novel medicines from the 19th century onwards, plant medicines … Read More

Is there science in reflexology? - BioBlog

Alison Campbell Jun 06, 2018

I subscribe to the Tertiary Insight newsletter (a great way to keep up with news of what’s happening in the tertiary sector). Yesterday’s edition included a statement (& a link) about the NZQA’s decision to cancel the registration of the Aromaflex Academy. It seems that this Private Training Establishment (PTE) was placed under strict conditions in January 2018, & … Read More

Could – & should – the moa be a goer again? - BioBlog

Alison Campbell Jun 03, 2018

I’m starting to gear up for some Schol Bio preparation days in the regions (hi, Hawkes Bay! See you in 4 weeks!) and realised that I haven’t written anything specifically focused on those exams for a while. So I thought that putting something together would be a good way to spend a rather wet Sunday. At these days we usually … Read More

Madonna teaches us a lesson in critical thinking - Open Parachute

Ken Perrott Jan 25, 2017

  Maybe just a small lesson – but an important one. We should always look at context and not cherry-pick that which confirms our bias. In particular, we shouldn’t simply repeat social media claims without doing a bit of fact-checking for ourselves. It’s an important lesson at the moment because there is a lot of this going on in the social … Read More

Critical thinking, not censorship, is the solution to fake news - Open Parachute

Ken Perrott Jan 09, 2017

All this talk about fake news brings to my mind a picture of people in glass houses frantically throwing stones. The fact is that many of those complaining about fake news, especially those dominating our mainstream media, are guilty of promoting fake news – and have done it for years. I can’t help thinking what really upsets them, is that … Read More
