Teaching as storytelling

3 Jan

I’ve never subscribed to the current vogue In HE of ‘Lecturing = BAD, anything but Lecturing = GOOD’, but I’ve bever had a particularly good argument against it, beyond ‘Look what David Attenborough does, it’s just an illustrated lecture’. I’d happily acknowledge that bad lecuring is probably the worst sort of teaching, but I’m just not convinced that all lecturing is inherently bad. All f that said, I was really pleased to come across this paper over the Christmas break :

The paper is facinating to me for a couple of reasons, in that it rather perfectly sums up my approach to teaching and I have no recollection of having read it before, even though it comes from a time what I had just begun teaching in HE.

So, a genuine question for those who believe that ‘lecturing’ is bad. If ‘storytelling’ has been the means of passing on knowledge for the vast majority of human history, why now is it a problem ???

Why teaching rational thinking is vital

2 Jan

As my own institution undergoes one of it’s regular ‘reorganisations’ my mind has turned to trying to explain why the sort of teaching I do is so important. In a period when UK HEIs are under existential threat, just saying ‘critical thinking is a valuable graduate skill’ seems like a rather weak justification for my work !

As every, the British media provided me with inspiration, when I came across this article, published in the Daily Mail on New Year’s Eve, and headlined ‘Chemotherapy may cause breast cancer to SPREAD: Two commonly used drugs encourage the disease to develop in the lungs’.

Even before I get to the details of the reporting, it’s worth dwelling for a moment on the potential impact of this article. Imagine reading this article as a patient undergoing breast cancer treatment. You’re first reaction might be to telephone your doctor, but it’s New Years Eve, so the chances are that you won’t be able to speak to anyone about it until after the New Year’s Day holiday. Thus you’d have two days of dwelling on the idea that the treatment you were currently getting might actually be harming you.

Before I get into the details, it’s worth saying that there is absolutely nothing wrong with the underlying research here, indeed it’s work from a reputable group, published in a reputable journal. I’d suggest that the fault here lays with the reporting of the original research. So have a look at what the issues might be :

  1. No link to the original paperThe original paper on which the article is based is freely available online, and thus it would have been simple for the newspaper to link to it. You might argue that the vast majority of readers wouldn’t understand the detailed content of the paper (me amongst them !!!), but having access to it does let the unqualified reader pick up some points that the newspaper ‘glossed over’ !!!
  2. Details of the study – The newspaper article refers to working with ‘experimental tumour models’, but nowhere does it explain that these ‘experimental tumour models’ are actually mice ! Return for a moment to putting yourself in the shoes of a cancer patient reading that article, and imagine how less stressed you Ould have been had the headline included the additional two words ‘…in mice’.
  3. Burying what the original authors said – As is often the case, the newspaper article buries the original authors comments at the very end of the article, in this case saying ‘not to jump to conclusions because they don’t if they’s get the same results with human breast cancer’. If you’d only ever read the Daily Mail article that seems like a very odd think for the original author to say, as you’d be assuming that the whole thing was about human, rather than mouse breast cancer.
  4. Ignoring important stuff – Additionally, if you had access to the original journal article you’s find another line that the Daily Mail omit to mention completely. Towards the end on the paper the original authors say ‘However, it should be cautioned that we did not study the survival of mice in association with the various treatments, so we currently ignore whether increased metastatic seeding and outgrowth in response to chemotherapy-elicited EVs would trans-late into shorter survival in our experimental cancer models’. So, the very variable that our imaginary reader might be most worried about (survival rate) wasn’t even studied !!!

Why is any of this even vaguely relevant to teaching rational thinking ? I’d argue that it’s two-fold:

  1. A reader who is clear on some of the basic tenets of rational thinking i.e. media literacy, how science works, and reading journal articles, would be in a position to be much less stressed that they otherwise might be about such reporting.
  2. This might be wishful thinking, but a populous educated in rational thinking might encourage newspapers to stop this sort of reporting !!!!

 

My 2017 Rational Thinking Book of the Year

3 Dec

At the beginning of 2017, having been bed-ridden with pneumonia, I discovered the wonderful world of podcasts. I’ll write a separate post about why I love podcasts, and what my favourite ones are, but this is the story of a book I discovered after listening to an episode of the excellent Freakonomics Radio podcast.

New-Freakonomics-Radio_logo3

In this particular Freakonomics Radio episode, Stephen Dubner interviewed the economist Seth Stephens-Davidowitz about his work and his new book “Everybody Lies: What the internet can tell us about who we really are”

If you’ve read anything else on this blog, you’ll know that I’m fascinated by behavioural economics, and Stephens Davidowitz’s work in particularly interesting as during his economics PhD he hit on the idea of using Google Searches to study human behaviour. If you listen to the podcast you’ll get a good feel of the idea, but put simply, it addresses two problems that dog a lot of psychology research. Firstly, Google’s almost monopoly position means that they have an enormous volume of data from populations all over the world (addressing psychology’s issues both with relatively small samples and over reliance on student participants), and secondly people’s on-line behaviour is more reflective of their actual views than might be the case in face-to face discussion (The ‘social acceptability’ problem). Stephens-Davidowitz nicely illustrates this point with is discussion of racism. In traditional face-to face psychology research it is very unlikely that participants will explicitly express racist views, and yet by looking at Google searches for obviously racist terms one can access a sea of information that would be otherwise hidden.

“Everybody Lies” is written in an entirely accessible style, so would be comprehensible for a non-social scientist, but I’d hugely recommend it to anyone interested in psychology, sociology or indeed politics. Indeed, given the omnipresence of Google it maybe ought to be required reading for anyone interested in the future and the currently fashionable topic of ‘big data’. Certainly, if your looking for a Christmas present for anyone of an ‘academic’ disposition this is the book to go for.

Finally, for the more scientifically inclined, my own conclusion from reading ‘Everybody Lies’, was that there maybe a paradigm shift coming in how science works. I’ve grow up with the idea that science begins with ‘theory’, and one collects data to test that ‘theory’. My thought was that ‘big data’ does away with theory i.e if we can conclusively demonstrate from the data that A is related to B do we any longer need to thing about WHY A might be related to B ? As it turns out this is not the most original of thoughts, but is is intriguing to think that in the future scientists job might be the ‘why’ part of the question, because ‘big data’ analysts will already have demonstrated the ‘what’.

 

Rational Thinking about what’s happening in the USA

8 Mar

“Democracy cannot succeed unless those who express their choice are prepared to choose wisely. The real safeguard of democracy, therefore, is education.”  Franklin D. Roosevelt

My last few posts here have discussed critical thinking/rational thinking in the light of the current changed political climate in the UK and USA, but this week I’ve focused on a couple of more concrete examples. Since the beginning of the US Presidential Election campaign we’ve got used to Donald Trump eccentric use of Twitter, but this week has seen a couple of tweets from the President that are particularly interesting :

snip1

snip2

Whilst the accuracy of both of these tweets has been fairly rapidly questioned, I found the second, in particular, interesting about what it says about the rational thinking both of the President and of the 50,000+ people who have ‘liked’ it on Twitter. Within minutes of that tweet it has been demonstrated that of the 122 Guantanamo detainees who had returned to terrorism after release only 11 had been released during Barack Obama’s Presidency, the remaining 111 had been released by previous Republican President, George W Bush.

Now, what interested me here was the President’s thought process around this tweet. It seems to me that there are a couple of potential explanation:

  1. The President believes his sources of information i.e BreitBart and Fox News, and doesn’t question their content
  2. The President is aware that only 11 were released by Obama, but knows that the tweet will reinforce the view of Obama held by his supporters, and thus they will not question the accuracy of the information.

Both of these explanations have serious implications for rational thinking. If the first explanation is correct, it suggests that it’s possible to win the US Presidency without the media literacy we’d expect of an undergraduate student. The second explanation, suggests a highly honed understanding of rational thinking and a deep understanding of ideas like confirmation bias. Whilst explanation No.1 is appealing to those of a liberal mindset, it seems to me that explanation No.2 is much more likely, and much more serious for those interested in critical/rational thinking.

Up until now, the development of thinking skills has been a fairly esoteric discussion limited to those directly interested in education but it now seems more than ever that Roosevelt’s quote that opens this post is vital. Those of us interested in such things can no longer tolerate vague scholarship, as it the very vagueness in the scholarship of critical/rational thinking that can be used against us. I’ll end with a question:

What would you say if the lead administrator of your School/University came to you and said “If you can’t even agree amongst yourselves about what critical thinking is, why am I paying you to teach it ?”

 

My first attempt at making video content

6 Mar

I’ve just finished my first attempt at making short video content focused on teaching rational thinking. My intention is that this will be the first of a series, but I’d really value any feedback
