A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring.
(Alexander Pope,
An Essay on Criticism)
When I was in my teens (which in my case lasted until I was
at least 30), my father, an otherwise kind and gentle man, used to say to me on
occasion, shaking his head in disbelief: “Kevin, you might be clever in some
things … but you’re bloody thick in others”. (I think it was his use of the
word ‘might’ that really got to me; expressing a degree of doubt.) On mature
reflection, I suspect that he was often, if not always, right.
Of course, anyone who has spent any time on university
committees will know that the most eminent folk, who are certainly ‘clever in some
things’, can be remarkably stupid in others. The almost childlike behaviour of
some academics is quite extraordinary. So it should come as no surprise that some
otherwise smart and accomplished professionals, such as teachers, are capable
of espousing the most curious beliefs. But I get ahead of myself …
Over the past twenty or so years, we have seen extraordinary
developments in brain imaging technology such that we now have a much clearer
and deeper understanding of how the brain works. At the same time, and
notwithstanding this amazing progress, we still have much to learn. Perhaps
even more importantly, we still have much to learn about how to put this new
knowledge about the brain into practical everyday use. This has not stopped,
however, a tidal wave of psychologists, educationists and others from wildly
speculating about new ‘brain-based learning’. (I leave it to the reader to come
up with examples of non-brain-based learning; elbow learning perhaps …?)
Seemingly everywhere one looks, there is news of yet another brain-based
teaching method. (Sometimes old wine is simply rebottled with a brain-based
label.) My Macquarie colleagues Anne Castles and Genevieve McArthur have
recently written an excellent opinion piece on this topic (http://tinyurl.com/9eqrnoa), featuring the recently much
vaunted Arrowsmith Program, as a prime example.
Alongside this craze for all things brain-based, or ‘neuro’,
a smaller movement has arisen, of desperate evidence-based psychologists and
educators, seeking to temper enthusiasm with reality and to dispel some of the
nonsense spouted by the ‘brainiacs’, also known as ‘neuromyths’. (A less polite
term that you might also encounter online is ‘neurobollocks’.) Like zombies,
however, neuromyths are extremely hardy and merely providing contrary empirical
evidence is rarely sufficient to kill them off. They might pause, briefly, but
then they keep on coming. And they breed …
The extent of this problem is revealed in a recent article by
Dekker, Lee, Howard-Jones and Jolles, published in Frontiers in Psychology (http://tinyurl.com/8wsjczw) which
reports the results of a survey of 242 teachers conducted in the UK and the
Netherlands. Over 90% expressed interest in ‘scientific knowledge about the
brain’ and 90% were of the view that such knowledge would positively inform
their teaching practice. The teachers responded to an online survey that mixed
a selection of neuromyths with true statements about the brain. In addition to
the collection of background information (about age, sex, level of education
etc), they were also asked about their degree of interest in scientific
knowledge about the brain and its influence on their teaching, any
‘brain-based’ methods they had encountered in their school, and whether they
read popular science magazines or journals, among other questions.
Over 50% of the teachers indicated that they believed in seven of the 15
neuromyths included in the questionnaire. Over 80% expressed belief in the
following: “Individuals learn better when they receive information in
their preferred learning style (e.g., auditory, visual, kinesthetic)”;
“Differences in hemispheric dominance (left brain, right brain) can help
explain individual differences amongst learners”; and “Short bouts of
co-ordination exercises can improve integration of left and right hemispheric
brain function”. Over 80% of the British teachers had encountered Brain Gym (specifically)
and learning styles (generally) (98%) in their schools.
So far, so bad; but it gets worse,
much worse. When the researchers examined the results in more detail, they
found that teachers who actually knew more about the brain tended to believe in
more neuromyths. Yes, that’s right; the more
they knew about the brain, the more
neurobollocks they believed! As the authors put it:
“These findings suggest that
teachers who are enthusiastic about the possible application of neuroscience
findings in the classroom find it difficult to distinguish pseudoscience from
scientific facts. Possessing greater general knowledge about the brain does not
appear to protect teachers from believing in neuromyths.”
A little learning is, indeed, a dangerous thing, as Pope
asserts. Later on, in the same work, he also cautions: ‘Fools rush in where
angels fear to tread’. Quite.
