Why we forget the things we learn
Georgina
Hello This is 6 Minute English from BBC Learning English I’m Georgina
Rob
And I’m Rob
Georgina
Do you have a good memory, Rob? Can you remember people’s names, or where
you left your car keys?
Rob
Well, I can remember people’s faces, but I have a terrible memory for names And
sometimes I’ll be eagerly reading a book but then a week later I can’t remember
a single thing about it!
Georgina
Well, you’re not alone Many people find it hard to remember things they’ve read
or learned while other, sometimes useless, information sticks with them
Rob
In this programme, we’ll be finding out why we forget the things we’ve learned,
whether that’s someone’s name, a word in English or where you put your wallet
Georgina
But first let me ask you my quiz question, Rob - before I forget You and I might
struggle to remember someone’s phone number but Chinese student, Chao Lu,
has a record-breaking memory In 2005, she recited the numbers of pi, the
mathematical equation describing the proportions of a circle – but how many
digits did she manage to remember? Was it:
a) 48,000?
b) 68,000? or
c) 88,000?
Rob
Wow! It sounds like Chao Lu has an incredible memory! I’ll say she remembered
b) 68,000 digits of pi
Georgina
OK, Rob, let’s remember to find out the answer at the end of the programme
Rob
OK, will do Someone like Chao Lu might have a photographic memory – the
ability to remember things in exact detail, like looking at a photograph But for
the rest of us, things are more complicated
Georgina
Dr Jared Horvath is an educational neuroscientist at the University of Melbourne
According to him there are two rules which explain how we remember
information
Rob
Listen to Dr Horvath talking to BBC World Service programme, The Why Factor,
and see if you can hear the two rules he mentions:
Dr Jared Horvath
Rule number one is repetition is key The odds of remembering something after a
one-off are incredibly slim…unless you can immediately link it to something you
already understand – so, my middle name is Cuney… if I ever meet someone
named Cuney I’ll never forget that ‘cos I have an immediate link… but if I meet
someone named Joe… so a one-off, we all pretty much suck at it - unless we
focus So then rule two then becomes, we remember what we focus on
Georgina
The first rule for remembering is repetition The odds – meaning the probability,
of remembering something are low if you learn it as a one-off - something that
only happens once
Rob
Dr Horvath’s second rule is about focus: we remember what we focus on This
involves making links between new information and something you already
understand
Georgina
These are the most effective methods of remembering, and most of us suck at –
or are bad at – other ways of remembering things
Rob
Now, of course, one group of people who need good memory is students Do you
remember cramming for school exams, Georgina?
Georgina
Ah yes, staying up late trying to revise everything the night before an exam I
remember doing that - but it didn’t work!
Rob
Yes Dr Horvath’s research found that students who cram for tests forget around
90% of what they studied within 72 hours
Georgina
He thinks education shouldn’t be about trying to cram students’ heads with facts
and figures It should involve something more meaningful, as he explains to BBC
World Service’s, The Why Factor:
Dr Jared Horvath
The thing that I like about education is its really moving from a model of ‘just
memorise as much as you can’ into what we now call deep learning which is,
instead of giving you a hundred things and I just need to know that you can
remember them, I’m going to give you ten things and instead of just being able
to remember them, I want you to be able to describe it deeply and come up with
new ways of looking at it
Rob
Traditionally, education involves memorising – learning information exactly as it
is so that you can repeat it later
Georgina
But being able to repeat something like a parrot doesn’t always mean you
understand it Dr Horvath advocates a technique called deep learning – a
complete way of learning something that means you fully understand and will
not forget it
Rob
So, remember: repetition, focus and deep learning are the memory muscles we
need Maybe that’s how Chinese student, Chau Lu, developed her record[1]breaking memory You do remember your quiz question, don’t you, Georgina?
Georgina
Yes, thank you, Rob - my memory isn’t that bad! I asked you how many digits of
the mathematical equation, pi, she could remember
Rob
And I said b) 68,000 digits
Georgina
Which was… the correct answer! Actually, the number was so long it took her
over 24 hours without a break to recite it all!
Rob
Oh Wow! Her brain must have be aching after all that OK, let’s recap the
vocabulary from this programme starting with a photographic memory which is
the ability to remember things in exact detail, like looking at a photograph
Georgina
The odds of something happening mean the chances that it will happen
Rob
A one-off is something that only happens once
Georgina
To suck at something is an informal way to say ‘be bad at doing something’ It’s
more common in American English
Rob
If you memorise something, you learn it exactly so that you can repeat it later
Georgina
And finally, deep learning describes a complete way of learning something so
that you fully understand it and will not forget it
Rob
OK, well, that’s all from us, but don’t forget to join us again soon for more
trending topics and top tips to help you remember useful and everyday English
vocabulary Bye for now!
Georgina
Bye!
