Shaping: Most famously getting pigeons to play ping-pong. Two pigeons on either side of a table-tennis net, with a ball Food reinforcement used to encourage movement in the direction of the ball Then gets more specific, only for pecking at ball Then only in direction of net Then only getting over net Remarkably fast: whole training takes only about ten minutes Relies on skill of trainer of course, detecting the desired behaviours and reinforcing them Used in “clicker” training of animals
Schedule—reinforce every time and it is mere bribery. The learning has to be established in its own right. Value—food is a reinforce to a hungry animal but not to a satiated one Anticipatory avoidance learning: see http://www.learningandteaching.infolearninga_a_learning.htm Learned helplessness: see www.learningandteaching.info learninglearned_helplessness.htm
Perspectives on Learning - Presentation Transcript
A Framework for Understanding Learning Perspectives PGCE Secondary 9 October 2009 James Atherton www.bedspce.org.uk/2dary
This is a annotated and expanded version of the slides from the lecture itself; which should make sense when read in conjunction with the web-page.
Annotations and additional material are shaded like this page.
What do we need to learn this for? Rather than go on about what my aims and objectives are for a session (because that is teacher-speak, not learner-speak) I prefer to try to answer the question students actually ask
How to think like a teacher We are supposed to be covering “learning theories”, but we need to think about the status of that knowledge. Is it just “inert” stuff we know about, or is it something which informs thinking and practice? So I want to offer an orientation to those theories, which will help you to put them in context and use them as you acquire more knowledge about them
Some ideas are like “thresholds”—once you get them you can cross to a different level of understanding
The Tardis is a great illustration of what happens when you go through some conceptual doors; the space is bigger on the inside than on the outside
Health Warning!
Not “scientific” If you are a natural scientist or an engineer, you will be disappointed in learning theories. None of them have the predictive capacity you will have come to expect in a theory. Instead, they offer different perspectives which you might find useful. In that sense they are more like “myths”, as the anthropologists use the term. It is more important that they be useful than that they be true.
Fads and fashions Which of course makes them prone to influence and abuse, and to the whims of fashion.
Such as...
“ NTL” model Practice by doing Discussion Demonstration Audio-visual Reading Lecture 75% 50% 30% 20% 10% 5% Teachback 90% Take this model which appears in practically every introductory text on learning. It is supposed to be about the proportion of material which can be recalled after being learned under certain conditions. It is attributed to “National Training Laboratories, of Bethel Maine” but even they don’t know where it came from, or what, if any empirical basis it has. But it does look plausible, doesn’t it?
versus rights/globals/ deductives/ simultaneous processors
executive, hierarchic, conservative versus legislative, anarchic, liberal.
Then there are “learning styles”; here are just some of them identified by Coffield et alI (2004 )
How more explicit could we have been? Let me try harder this time. There is no scientific justification for teaching or learning strategies based on VAKT and tutors should stop using learning style instruments based on them. There is no theory of VAKT from which to draw any implications for practice. It should be a dead parrot. It should have ceased to function.
Coffield F (2008) Just suppose teaching and learning
became the first priority... London; Learning and Skills Network p.32
(emphasis in original)
The report’s conclusions that learning styles theories were almost all pernicious rubbish which undermined good teaching were not greeted enthusiastically. Coffield returned to the fray with this in 2008
Theories of learning are based on a range of assumptions about learners and the learning process, which may have historical, political or cultural roots...
Images of Teaching and Learning On other courses I frequently ask people to represent their images of the learning process, graphically. These are some which come up fairly frequently
So I asked you to spend two or three minutes talking to people around you and sharing your preferred assumptions and models.
Afterwards I asked a few of you to tell us about any new images. Among others, you suggested;
A growing tree
A rocket (or a ship) launching on a journey
Casting a pebble into a pond...
A common theme was the learners’ self-direction, choice and autonomy.
It has not always been thus...
Learners...
Are empty vessels
Are black boxes
Are growing up
Are lions to be tamed
Are audiences to be entertained
Are collaborators
Are…
These are some of the underlying assumptions behind different theories of learning
...have to be tamed
Break their will betimes . Begin this work before they can run alone, before they can speak plain, perhaps before they can speak at all. Whatever pains it costs, break the will if you would not damn the child. Let a child from a year old be taught to fear the rod and to cry softly; from that age make him do as he is bid, if you whip him ten times running to effect it... Break his will now, and his soul shall live, and he will probably bless you to all eternity.
(John Wesley, cited in Southey, Life of Wesley )

Are empty vessels Thomas Gradgrind now presented Thomas Gradgrind to the little pitchers before him, who were to be filled so full of facts. Indeed, as he eagerly sparkled at them from the cellarage before mentioned, he seemed a kind of cannon loaded to the muzzle with facts, and prepared to blow them clean out of the regions of child-hood at one discharge. He seemed a galvanizing apparatus, too, charged with a grim mechanical substitute for the tender young imaginations that were to be stormed away. "Girl number twenty," said Mr. Gradgrind, squarely pointing with his square forefinger, "I don't know that girl. Who is that girl?" (Dickens, 1854, ch 2) Learners are passive recipients of what authority chooses to fill them with, and have to be made malleable to be formed into whatever the industrial age demands

It’s just obvious. Innit?
Are black boxes ? According to behaviourist theory

Watson
Professor of Psychology at Johns Hopkins University
Believer in the power of the environment :
“ Give me a dozen healthy infants ... and my own specified world to bring them up in, and I'll guarantee to take any one at random and train him to become any type of specialist I might select — doctor, lawyer, artist, merchant-chief and yes, even beggar-man and thief— regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors. ”
Left university after a scandal in 1920, to sell rubber boots
But behaviourism has a great confidence in the power of the environment to shape behaviour; hence it can be very radical. This claim was made in 1916!
Burrhus F Skinner
1904-1990
Most prominent behaviourist
Operant conditioning
Sets out the power of reinforcement (chiefly, loosely, reward) to shape behaviour. Still very influential re. SEN, psychomotor training, etc.
Operant conditioning
Behaviour which is reinforced is more likely to be repeated.
This behaviour can be shaped by progressively more specific reinforcement
Reinforcement of desired behaviour is more effective than punishment of undesired behaviour.
JSA
Operant Conditioning 2
Lack of reinforcement leads to extinction
The schedule of reinforcement is complex
Reinforcement depends on the value of the reinforcer to the subject
Reinforcement can be the absence of a noxious stimulus
” anticipatory-avoidance learning”
Loss of connection between reinforcement and action leads to passivity and fatalism (“learned helplessness”).
JSA
Applications
Break down learning into behavioural steps
Reinforce for success
Do not punish for lack of success
Establish (“stamp in”) each step before proceeding
Limited by self-imposed constraints of diminishing relevance
Limited applicability in real-world human learning
Project undermined by “ Cognitive Revolution ” from mid-70s onwards:
Understanding of genetic influences
Ability to trace brain activity
Chomsky on language.

Growing up Are children just little adults, who have not yet had time to acquire all the knowledge of a grown-up? Or do they think differently, so that learning needs to be tailored to their maturing capabilities?
Jean Piaget (1896-1980) Piaget has been hugely influential in researching and explicating the latter view.
Piaget’s big idea
The capacity to think depends on growing up
“ Unfolding” capacity
Stages of readiness to learn
“ Genetic epistemology”
Similar to stages of physical growth (“milestones”)
Ability to hold head up, sit up, walk
… through to puberty
(A few brief examples follow for illustration only)

Jean Piaget (1896-1980) Piaget
Are lions to be tamed; the teacher is a lion-tamer
Are audiences to be entertained; the teacher is an entertainer.
Are collaborators; the teacher is a “new romantic”
(Hargreaves)
Hargreaves suggests that these are three myths about students held by their teachers. Each of them contains a profound implied theory of learning, and they are undoubtedly much more influential than the academic theories
