Mind Mapping – Tony Buzan, Learning leader

MM-How-to-MindMap-imindmap-1024x647

It was with some sadness that I read of the death of Tony Buzan last week. It’s possible you have never heard of him and yet will be familiar with the technique he discovered to help students learn, Mind Mapping. He was born in the UK in 1942 studied Psychology, English, Mathematics and Science at the University of British Columbia.  In addition to his lifelong association with Mind Mapping he worked for Mensa, set up the World Memory Championships in 1991 with Raymond Keene, and found time to write over 140 books. Two of which sit on my bookshelf, both furthered my knowledge and fuelled my interest in learning, memory and how the brain works. These are Use your Head and The Mind Map book.

Curiosity  

When Tony Buzan was at Junior school his curiosity was sparked by a boy who had an excellent knowledge of nature, in particular birds but repeatedly failed tests that were set in school. This led him to question what intelligence was. And although I hadn’t read this at the time it was something I had also been interested in. Society had/has somehow lost sight of the fact that people are different, falling into the trap of praising and promoting those that were “clever” and pitying those that were not. It seemed far more sensible to break intelligence down into a series of biological/neurological qualities, and in 1983, when Howard Gardner published his book on Multiple Intelligence Theory this made perfect sense to me and provided evidence that Buzan was on to something.

Mind Mapping – does it work?

According to Tony Buzan, “Mind Mapping is a two-dimensional note-taking technique with which a Mind Map is made using all the relevant knowledge about a specific subject.”

I have written about how to Mind Map before, so please follow the links if you want to find out more – Mind Mapping unplugged – The De Vinci code – Mind Mapping to pass exams.

Remarkably there is little evidence to prove that Mind Mapping works, academics have focused instead on Concept Mapping, a hierarchical diagram that links conceptual knowledge, but the principles that underpin Mind Mapping are consistent with much of what we know is effective in learning.

This quote from Tony Buzan offers a deeper insight into why it works.

“I used to take formal notes in lines of blue, and underline the key words in red, and I realised I needed only the key words and the idea. Then to bring in connections, I drew arrows and put in images and codes. It was a picture outside my head of what was inside my head – ‘Mind Map’ is the language my brain spoke.”

In this narrative there are three important principles identified. Firstly, use only key words, this process of reduction is hugely valuable in learning. When the brain has to select one or two words it engages in a process of reflection and review, reading and re-reading asking which one word should I pick, and why. Secondly connections, it is well accepted that the brain finds storing unrelated chunks of information difficult, a Mind Map requires the student to link information and in so doing forces a connection. And lastly, arguably one of the most powerful, the use of images. The brain appears to have a limitless capacity to store pictures, the brighter, more colourful and stranger the better.

In summary, it’s not that Mind Mapping was invented by Tony Buzan and before we knew little about the best techniques to aid learning, what he did was pull together much of what we now know to be effective using as inspiration the drawings of the Leonardo de Vinci and created a tool that requires the student to know little of the theory behind how it works but by preparing one engages them in a series of very effective techniques that will help them learn.

Critics

It would be wrong to suggest that everything Tony Buzan said or did was correct, he has been responsible for promoting what many now recognise as pop psychology that has since been proved to be incorrect. For example

“Did you know that you use less than 1% of your brain? The good news is that Mind Mapping can help you to access the other 99%.”

However, he also said

“Learning how to learn is life’s most important skill.”

And in this world rich with information, AI and robotics, this may be the only thing that will keep us ahead of the game.

Sleep, studying and Circadian rhythms

Circadiam - sleepThe brain is truly astonishing, if you disagree with that statement it’s just possible you have never heard of circadian rhythms.

Your circadian rhythm is best thought of as a body clock, a 24-hour cycle that tells you when to sleep, get up in the morning and eat. In biological terms the clock is called the suprachiasmatic nucleus or SCN for short. The SCN is a tiny part of the hypothalamus which is situated directly above the pituitary gland in the centre of the brain.

 

 

Your body has a clock
Do you wake in the morning naturally or is it the result of a stark shrill from your alarm? If its naturally then this is your internal clock at work. Interestingly it can be pre programmed, you will have done this many time, waking before your alarm goes off for example. We are not talking about 10 minutes before, so accurate is your body clock you can wake 1 minute or even seconds before it is due to go off. Jet lag is an example of what happens when you disrupt the internal clock, your entire body struggles to adapt, affecting your ability to concentrate, eat, rest and sleep.
Interestingly Circadian rhymes exist in all living organisms, including plants. The external stimulus is natural light. However even without light the 24-hour cycle will continue, this has been evidenced by research with people who are totally blind. Although their circadian rhythms are often said to “free run” and extend slightly longer than 24 hours, they continue independent of light.

Why is this important for studying?
One of the reasons for going into so much detail is to illustrate how complex we are as human beings and that what may seem a relatively small change in your behaviour e.g. studying late into the night, can have a significant impact on your ability to function, in this context concentrate and remember.
Pulling an all-nighter to prepare for an exam is a badge of honour that many students will wear with pride. It is perceived as a measure of how committed and mentally tough you are. And on one level the effort and difficulty of the task should be rewarded, but given that examinations are a test of cognitive ability anything that reduces your chances of doing well should be avoided. If Hussain Bolt ran the 100 meters in a record time, having been out on the town the night before, waking up with a hangover and only having two hours sleep he would be a hero. But if he lost, he would be a fool. Why would someone who had invested so much of their time put that at risk?
In simple terms you need to help your brain perform to the best of its abilities.

Circadian rhythms and memory
A little more technical detail to illustrate a simple point, if you don’t follow your natural sleep patterns your ability to memorise and retain information will be affected. Retention appears to hinge on the amount of a neurochemical called GABA which inhibits brain activity. And it is the Circadian clock that moderates the amount of GABA produced. In fact, in an experiment using hamsters where the circadian clock was effectively disabled the hamsters were unable to remember anything.

Mental health types-01There is a far more sinister side to the disruption in your circadian rhythm, ongoing research has identified a direct link with mental health disorders such as depression. This is of particular interest given the rise in reported levels of depression amongst students. One area that is being investigated is screen time be that mobile phones or computers. The artificial blue light emitted from these devices could well be confusing your circadian clock.

Why we sleep is still uncertain but it is believed that deep sleep helps the brain consolidate all the experiences from the day, including what its learned. When you shut down your computer, it may say “do not turn off during this update” – that sounds like  good advice.

Storytelling – The cave

telling stories

There is a lot written today about the power of storytelling and how it can help persuade, influence and of course educate. Stories come in many shapes and sizes, sometimes they are true, but might be embellished, sometimes they are not true but include powerful messages hidden in the form of metaphor or allegory.

The simplest definition of a story is that “one thing happens in consequence of another,” and it can engage, motivate and inspire. But cognitively the brain is working very hard forming connections, asking questions, creating images and helping offer up opinion.

“If you want your children to be smart, tell them stories. If you want them to be brilliant, tell them more stories.” Albert Einstein.

Below is an allegory, arguably one of the most important in the whole of western philosophy, but its message for educators and students is sometimes lost. It’s called Plato’s cave, read it carefully, thinking about what it might mean.

Plato’s cave
Plato caveAlthough Plato is the author, it is Socrates who is the narrator talking to Plato’s elder brother Glaucon.
The story told is of a group of people who from birth have been chained up in a cave with their heads fixed in one direction so they can only look forward. They face a cave wall on which they can see moving images, shadows that they believe to be reality. Socrates’s explains that when the prisoners, because that is what they are, talk to each other they discuss the shadows as if they were real. But they are an illusion, created by shadows of objects and figures played out in front of a fire, manipulated by the puppeteers.

Socrates goes on to say that one of the prisoners breaks free of his chains and is forced to turn around and look at the fire, the light hurts the prisoner’s eyes but as they adjust, he can see the fire and the puppets he had believed to be real. He doesn’t want to go any further fearing what it might bring but once more is forced to go towards the mouth of the cave and into the blazing sunlight.

At first, he can only look at the reflections because as with the firelight the sun is too bright but as his eyes adjust once more, he finally looks at the sun, only then “is he able to reason about it” and think what it could mean. His thoughts are interrupted by the sorrow he feels for his fellow prisoners who have not seen what he has, have not learned the truth. So, he goes back into the cave to tell them everything. But when the prisoners look at him, they see a man stumbling, strained, no longer able to see in the dark cave. But worse when he begins to explain they think him dangerous because what he tells them is so different to what they know.

The prisoners do not want to be free, the effort is too great, the pain and apparent disability sufficient to stop them trying. They are content in their own world of ignorance and will fight anyone who wants to change that.

But what does that mean?
The answer of which should be, well what do you think it means? But sometimes you just don’t have time for that answer so here is one interpretation, it’s worth pointing out there are many.

  • The puppeteers are those in power or authority. They prefer it if people don’t ask questions, remain content and are not causing trouble.
  • The fire is knowledge and wisdom.
  • The prisoners are society.
  • The escaped prisoner is the student. The student who through education escapes and finds answers.
  • The person that frees the student and drags him towards the light is the teacher.

If we put this all together, it gives us an insight into learning that has remained unchanged since Plato wrote the Republic in which this story sits in 514a–520a.

Learning is not easy, it can be difficult and hard work. Some people are happy to remain as they are, ignorant, after all it’s not pleasant having your beliefs challenged and finding out that what you thought was true in fact isn’t. Teachers can help take you towards knowledge and learning but you need to want it for yourself, and once you have knowledge you can’t go back to what you were before, education will have changed you forever.

Making complex simple – the measure of a great teacher.

solve-the-equationRichard Feynman who featured in last months blog was known as the great explainer. This skill was possible because of two key qualities, the first, an intense curiosity and desire to understand the subject incredibly well and secondly, he could make what was complex seem simple. These are of course not mutually exclusive, deep understanding is the foundation on which simplicity is built.

There was a time when getting access to knowledge was a barrier to learning. After all, how could you learn if you didn’t have the books from which to do it? But we no longer have this problem, knowledge is abundant, it is literally at the end of your fingertips.

The world’s knowledge is just waiting for you to ask the right question. But how can you tell if what your reading is shallow and without thought or deep and profound?

Jardins principle
In 1997 I read an article in the Financial Times written by Rob Eastaway, an English author whose books on everyday maths include Why Do Buses Come in Threes? and The Hidden Maths of Sport. For some reason the concept he outlined always stayed with me, sufficient that I wanted to track it down, which I have managed to do.

Jardin’s Principle as explained by Rob Eastaway. If you are trying to understand any subject or system, your level of understanding will pass through three stages. To start with, the way that you see and describe a system (subject) will be simplistic i.e. over-simplified, then it will become complicated but ultimately it will become simple again. He goes on to add that there are three other words that fit in with this idea, Obvious, Sophisticated and Profound.

Make everything as simple as possible, but not simpler – Albert Einstein

Simple – Complex – Profound
As with all ideas there is more to it, below are what Rob refers to as the 5 caveats. I have added in my own thoughts and observations to some of them.

1. It is hard to differentiate between what is ‘simple and profound’ and what is ‘simplistic and obvious’. This is one of the main problems with a process of reduction, for example if you ask, what is the meaning of life you might be given the answer 42. The problem is in knowing if this is just two numbers written down, snatched out of the air or the correct answer, the result of hundreds of thousands of calculations undertaken over 200 years by the most sophisticated computer in the world?

2. Those at the ‘sophisticated/complicated’ level believe that there is no higher level than theirs – in other words you have to be sophisticated to understand fully. This is a clever observation on human nature, it suggests that some people believe you cannot fully appreciate a concept or idea unless you look at it through the lens of complexity. They effectively give up looking for a simpler perspective, because they don’t know one even exists.

3. You are probably wrong about the level of Jardin that you are at. An example perhaps of fish not seeing water.

4. In order to reach the profound level of understanding you usually pass through the other two levels first. This is my favourite because it shows that the route to simplicity is not easy and requires time and effort. You have to revisit your understanding many times before your brain springs into action with the blindingly obvious.

5. Unless you have a profound understanding of a subject, you will either over-complicate or over-simplify it. Perfect…..

Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it’s worth it in the end because once you get there, you can move mountains. – Steve Jobs

Great teaching  – Taking something that is complicated and making it appear simple is in many ways the essence of great teaching. Breaking down a subject into easily understood bite sized chunks of information or capturing the whole concept in one single leap by use of a metaphor or simple story is genius. But the process of getting to these pearls of wisdom involves wading through the mire of complexity in some instances for many years before the obvious reveals itself.

What I didn’t know at the time was that Rob had actually made this theory up, he didn’t want to put his own name to it so chose the French word for garden in homage to the Peter Sellers film, Being There, about a simple gardener who becomes US President.

Rob you ask, will it ever stick, maybe you should call it Eastaways folly instead.

The simple Mr Feynman

Feynman

Richard Phillips Feynman was co-awarded the Nobel prize for Physics in 1965 for successfully resolving problems related to the theory of quantum electrodynamics.  No, I’m not sure what that means either. If that was not enough he also helped build the atom bomb, being part of the Manhattan project, and following the Challenger explosion on January 28, 1986 he was the person largely credited with figuring out why it happened.

In fact, Richard Feynman is widely considered to be one of the greatest and most influential theoretical physicists in history. His physics lectures have become world famous. Here is one on the Law of Gravitation.

“I’m smart enough to know that I’m dumb.”

Richard Feynman

He was intensely curious and believed that unless you could explain a concept or idea in simple terms you really didn’t understand it. In this clip Feynman was asked by his father to explain where a photon comes from – listen for his metaphor.

The Feynman technique

Richard Feynman was worried that a lot of people thought they knew something when in fact they only had a superficial grasp of the subject matter.

“You can know the name of that bird in all the languages of the world, but when you’re finished, you’ll know absolutely nothing whatever about the bird. You’ll only know about humans in different places, and what they call the bird… I learned very early the difference between knowing the name of something and knowing something.”

Richard P. Feynman

Such was his concern that he created a process to help take an individual’s knowledge to a far deeper and more fundamental level, it’s called the Feynman Technique.

Step 1: Take a sheet of paper and write the name of the concept, topic or subject you would like to learn.

Step 2: Explain the concept in your own words as if you were teaching someone else – see also Protege effect.  Imagine your pupil is a small child, this will help focus your mind on plain, simple language. Don’t limit your explanation to definitions or overviews, challenge yourself, and include lots of examples, which as mentioned in earlier blogs is a great way of making sure you have understood it.

Step 3: Review your explanation and identify the gaps. These might be areas where you simply didn’t have the necessary knowledge or your explanation was weak. Once you have done this go back to your notes or textbook, re-learn the subject matter and add what you have learned to your sheet of paper, then repeat step 2.

“The first person you should be careful not to fool is yourself. Because you are the easiest person to fool”.”

 Richard Feynman

Step 4: Review again and remove technical or overly complex terms, think, “how can I say this more simply?” Also put your notes into an order that flows easily, this might involve rewriting large sections and even starting again with a clean piece of paper, but thats all part of the process. One final tip, as with step 2, it often helps to read out loud.

And that’s it!

I am not saying that if you follow this technique you will win a Nobel prize or be able to play the bongos, another skill that Feynman was famous for, but it will certainly deepen your understanding of the subject, and that’s not a bad start is it!

Engaged

There are a number of terms that crop up continually in learning, motivation, attention, inspiration, concentration, curiosity etc. But one that is becoming increasingly important especially for those students studying online, is engagement.

Many of the above terms are closely related and often used in the same sentence, but by taking some of them we can make an attempt at defining engagement – the degree of attention, curiosity, interest and passion demonstrated when learning.

Types of engagement

However when you look into any subject in detail it’s never as easy as you first thought. Fredricks, Blumenfeld and Paris identified three types or as they called them dimensions of engagement:

1. Behavioural engagement e.g. attendance, involvement and absence of disruptive or negative behaviour.

2. Emotional engagement e.g. interest, enjoyment, or a sense of belonging.

3. Cognitive engagement e.g. invested in learning, seek to go beyond the requirements and relish a challenge. A cognitively engaged student can become unaware of time and will be capable of taking the subject matter outside its context, form new connections and begin asking questions in order to ensure they have fully understood.

In simple terms an engaged student is physically, emotionally and mentally present.

Why is it important?

There is a large body of evidence that shows correlation between high levels of engagement and a number of desirable learning based outcomes, for example improved critical thinking, cognitive development, skills transfer, self-esteem, deeper understanding and better *exam results. It’s also worth adding that an engaged student is more likely to complete the course.

If you are not engaged, then what are you doing?

Engagement clearly helps students learn more effectively but it is also closely linked to motivation. In fact the expression motivated and engaged are sometimes used as if they were the same, but there is a subtle difference. I have written about motivation many times and unlike engagement tends to be more long term, possibly internal and certainly goal orientated. You can of course be engaged but not motivated, for example engaged in an activity, perhaps concentrating and interested but it’s not a topic or subject that you feel is important and have no long term need or desire to find out more. Engagement is the response to an external and immediate satisfaction, entertainment, curiosity, or recognition.

How to engage – for the teacher

As with motivation, it’s better to be engaged than not, so before we answer the question, what can teachers do to engage their students, it’s worth noting the role of the student, if you sit with your arms folded thinking of something else, you won’t engage.

  • Make it relevant – outline before you start why this topic is important for your audience. How is this online session going to help the students achieve their objectives, try to be specific.
  • Use real world examples – related to the above, a real world example can help the student appreciate the importance of what they are learning, i.e. if it’s used in the real world it must work. This may result in the student asking questions internally as to how it might work in their organisation or concluding that it will not.
  • Positive reinforcement – praise may sometimes feel artificial and of course should not be given all of the time, but recognising the difficulty of a task and congratulating everyone for doing well is both motivational and engaging.
  • Build rapport – use student names to help personalise the process. Break down barriers by saying what you personally find difficult, and perhaps why. If you can empathise with the student it helps build rapport, which makes it more likely they will listen and follow your advise.
  • Inspire – not everyone will think of themselves as inspirational but in some ways it takes very little, a simple story that means something to you can do the trick. Simon Sinek suggests that inspirational leaders know their WHY, they know why the are doing something. Ask what’s your why, and it’s not just because it’s your job, it’s because it’s your passion and fits with your personal beliefs.
  • Inclusive activities – plan for a number of activities that will encourage the group to engage with each other, the subject matter and you. These can be as simple as asking questions, setting quizzes, polls, or more involved, such as break out groups. Importantly the activities should not be easy, they need to be challenging, bored students are not engaged.
  • Manage and facilitate, don’t tell, ask – try to get the students thinking, ask them why, do you all agree, is there an alternative answer? It’s also a good idea to encourage students to think and believe in themselves, to become independent and autonomous learners.

And one last tip, make it short and don’t go on too long or labour a point, there is a danger your students will disengage!

Which is probably my queue to bring this to an end and wish you all a Merry Xmas.

Cramming works, but only until tomorrow

Cramming

I have written about cramming before or to be precise it was in the title of a previous blog but the main focus was on the benefits of attempting exam questions. As a result, I feel I should say far more about what many students reluctantly admit is their most commonly used study method.

Cramming is the process of leaving everything until the last minute and then studying intensely in a relatively short period of time. Students know they shouldn’t do it and yet the “cramming badge of honour” is often worn with pride. It is accompanied by the boast, “anyway I work better under pressure”.

Better under pressure

Yerkes and Dodson (Yerkes-Dodson Law) famously put rats in a maze and administered electric shocks as they attempted to choose between a black and white door. They noticed that mild shocks improved the rats’ performance until a certain point, after which it greatly decreased. A chart of the shock strength versus performance takes the shape of an inverted U. And although there has been some criticism as to the exact findings, the concept that people perform better under pressure is true but only to a point, and of course judging when that point is reached is personal and arguably impossible.

The conclusion therefore has to be that creating a stressful situation by leaving everything until the last minute is not a particularly sensible strategy. An exam environment brings its own high level of stress without you having to manufacture your own.

Back to cramming

In June and July, I identified 6 scientifically proven learning strategies, and it is here that we can find the answer to the question, does cramming work?

Spaced practice is the process of studying over time compared with studying the same content but intensely at the end, normally prior to a test. The results as to which one is best is conclusive, spacing your learning is far better because you will not only improve what is called retrieval strength but also storage strength. The implications being that you will you be able to recall what you have learned quickly and the information will be stored waiting for when you might need it in the future.

However, studying at the end, effectively cramming also works, it has to, students have been using this method of revising since the very first exam. But, and there is a but, it only helps with retrieval strength, that is you will only be able to retrieve the information for a short period of time, perhaps as little as a day. Should you want to recall what you learned at some point in the future it won’t be there. The reason, a short burst constantly topped up will keep the information in short term memory but due to the lack of time the brain is unable to consolidate what you have learned, effectively taking it into long term memory. There is some evidence to support the view that this consolidation takes place when you are a sleep, something else that students who cram often don’t get, but that is a sufficiently large enough topic it would need a future blog.

Conclusions

Cramming does work for short term chunks of information for example formulas, key words that remind you of knowledge stored in long term memory, formats, illustrations etc. Simple memory techniques such as acronyms and acrostics are great and should be used, they are part of the tool kit of a professional student. But they are in addition to a more structured and spaced out way of learning, not an alternative.

Here are a few more resources.
