How fantastically big is this question, ‘What makes great teaching?’.
It’s quite a scary question for an actual teacher… because it challenges you to answer it! At first it sounds rhetorical, and perhaps we would all feel safer if it was. The question seems to be asking you to explain your professional worth and even your professional qualification. If you are given a few moments to jot down some bullet point answers, then you may struggle. Why? Well, if we listen to John Sweller (the TES referred to him as the ‘Godfather of Cognitive Load Theory’), then we can’t even begin to know about great teaching until we know about how the brain learns. Sweller says, ‘Without knowledge of cognitive processes, instructional design is blind’. In other words, we need to know about the brain in order to teach. No wonder ‘great teaching’, then, is so elusive. The brain is, after all, the most complex structure known to humankind.
It is wonderful to see teaching and learning led by education research. As a young teacher studying school/teacher effectiveness under Professor David Reynolds at the University of Newcastle in the late 1990s that was not the case. Practice and research were separate worlds… never mind conjoined…never mind research leading practice! So, it is really a watershed moment; Ofsted taking the best educational research on the entire planet and using it to underpin their inspection framework. And they have done it incredibly well! Common sense always rises to the top and this approach just makes sense! I particularly like the way the research leads straight into the specific criteria used by inspectors to make judgements. As a former inspector for Ofsted I know how it feels to be making judgements using criteria that have come from ‘nowhere’.
Driving Instructors have Cognitive Load Theory nailed
Imagine the driving instructor that
starts the very first driving lesson with;
‘Ok, I’d like you to overtake the car in
front using mirror – signal – manoeuvre. And that, my friend, is how you
Having no understanding of the cognitive
load they are placing on the learner’s brain, a disaster awaits. It is a
similar situation in any classroom where the learner has been asked to think
through more than their brain can cope with at any one time. When this happens,
learning fails. When it happens consistently, an educational disaster
Driving instructors are teachers
Driving instructors are teachers whose
learners’ lives depend on their teaching; some would say that school teachers
are the same! The responsibility of school leaders in this regard is greater
Driving instructors know full well that
their students need to master all three skills in isolation first (mirror,
signal and manoeuvre), before they can be combined into one process and then,
later on, through varied and frequent practice, one smooth
process, and then, later still, one smooth process that can be combined with
other skills. So, this 5 stage sequence is worth considering as a front door
them fluently in isolation first, then
them into one process with explicit teaching, and then
revisiting the ‘one process’ in gradually more challenging contexts until it is
‘one smooth process’, and finally
learner choosing to use and apply this new skill in an appropriate, and perhaps
unfamiliar, context. In other words this combined skill has now itself become
an automated ‘part-skill’ ready to combine with other part-skills that have
their own backstory.
The Cognitive Load Theory Learning Sequence
This simple CLT learning sequence is at
the heart of teaching children to become
numerate (see my blogs ‘Using Cognitive Load Theory to Crack Addition 1, 2 &3’).
In this way learning is always built upon learning. Fluency leads to more
fluency. CLT is much more than this; but when CLT is applied to a child
acquiring the basic skills for maths then this fundamental CLT principle of
‘keeping the cognitive load right for continued progress’ is everything!
Getting the load right
Imagine the driver that has already learnt to overtake expertly (whilst on ‘autopilot’) but, suddenly, one dark night the rain comes down hard on an unlit and unfamiliar road; wipers are going crazy, visibility is low and the driver hunches forward as they go to overtake. What would you do? You would concentrate! In doing so you naturally close down any conversations that were going on and give your full cognitive attention to the skill of driving as the complexity of the driving challenge increases. This experience maximises your learning; you are a better driver because of it. However, a cognitive curriculum exists between the first driving lesson and the expert driver. Hence, it’s not a just a case of making it easy if the content is new, and making it difficult once it’s easy (although that can be a good starting point). To optimise learning we need to find the delicate balance between the two.
As a learner, having just the right
cognitive demand is everything. As a teacher, providing just the right
cognitive demand is everything! Underload and progress stalls. Overload and
progress stalls. We teachers need to know the learner’s abilities, yes. We need
to know the specific curriculum content detail, yes. But we teachers also need
to be experientially rich in the practice of employing the principles of CLT if
we are to be able to respond to the learner’s academic needs by providing the
most suitable cognitive load for teaching their next learning step, whatever
that may be. Getting the load right is everything!
The very first sentence of the book
‘Cognitive Load Theory’ by Sweller, Ayers and Kalyuga
says; ‘Without knowledge of cognitive processes, instructional design is
blind’. I guess if they weren’t polite academics they might have written, ‘If
you haven’t studied how the brain works then don’t teach!’
Do you do it yourself or do you just like to watch? Blogging, I’m talking about. For a long time I’ve been on the outside, looking in…at bloggers. Some people take to it naturally (millennials probably), getting the load right. Not me though. I’m a reluctant blogger. My wife has been trying to persuade me to blog. Curtis (boss at Andrell Education) has been telling me to blog. My subconscious has been shouting at me to blog! But, my ‘conscious’ has been telling me to keep watching.
