Should teachers know science or neuroscience?



This question is constantly asked at different forums, science blogs and messages about education such as specialized in neuroscience and science. I personally read each one as because is the main theme of my writings. Yes, I think and believe that neuroscience can do a lot for education and my argument is time to put the brain in the classroom, and I do not tire of saying that science education benefits to any country at all levels, especially the economic. Can you interpret my phrases as you like, there is no a recipe.

My problem arises when other writers say: teachers should know neuroscience, and that joins a long list of duties, like teachers should know physics, math, history, chemistry, biology, astronomy, so they would teach it properly to students. Virtually any topic in which someone is expert, teachers must master it, so future generations can have a scientific education.

Of course the huge list of topics that we believe teachers can be experts, are added cleaning bugers, how separate fighters, reading of hieroglyphs, decryption key, taught to read and write, how to respond to questions such as: can I go to the bathroom?, can I deliver my homework tomorrow?, how do you know that I copied this from Wikipedia?, or what will you do to help my child with writing?. 

If teachers should be experts in so many fields, they would deserve to earn a higher salary. Being a teacher would be a good profession, (it doesn't mean is not, but it would be a better profession) and they would have enough money to read specialized magazines and attend all meetings, conference and forums organized by those who claim to know how to teach better and are part expensive conferences to share knowledge. Sharing is just a say by those experts in science, because they do not speak with simple mortals, they only charge a high bill by let you see them a couple of hours, recommending to buy their books, and follow them in social networks. 

If teachers have questions or want to share any idea, they have permission to speak. It doesn’t mean those questions will be answered, those ideas are not relevant. The relevance is decided by the expert, not you.

The question is then whether teachers should know science and how much they can apply it in their classroom, in a society that isn't interested in science.

Let's  split  this question, which is not as easy as it seems. 

The relationship of science to society

Once I read that it can’t be taught something that is socially shared, because teachers work with which society gives them to shape. If socially you aren't literate scientifically, it is not possible to provide the science from the experts, those lucky ones who have taken advantage from their enormous passion for a subject, often supported at home, because everything is much easier if you have other supports, in addition to school.

When people think about scientists the image is a brilliant mind able to respond to everything and understand the complexity of the world, it's partly an image that scientist themselves have created, however, science in numbers looks far from society.

Let me share some data. Between 1996 to 2010 were published 5,322590 Scientific articles in United States, and from those documents 4.972 679 are quotable, does that sound like many articles?, well, what about if we compared them with the population of The United States, 313,967,000 persons means that they are not so many articles, and if you accept that not everyone can read them, and each article sometimes costs between 20 and 40 dollars, maybe we can begin to see some distances.

The countries that follow in the list with more scientific production are China with 1,848,727 articles, but with a population of 1,347,350,000 persons; United Kingdom added 1,633,434 articles, and has a population of 62,262, 000 persons. 

At the other extreme of the data, The Vatican City State published 4 articles in the same period, but it has a population of 800 persons. The island of Saint Helena has a population of 4,255 and 1 published article. Of course the proportion is abysmal among the countries most gifted of scientific support. 

Does it look like The United States is a scientifically literate country?, I don't think so, because one of the topics given more headache is how to make that science can have better results. 

In a study applied in 2009 by the Organization for Economic Co-operation and Development to students 15 years of age between 65 countries, United States ranked 23th in science and 31st in mathematics. 

It is not the idea of this article to discover the black wire, but I think that the problem is between the distance of science with society. To argue this point, I propose some comparisons: Carl Zimmer is followed by 922 050 persons on Google plus, Hugh Jackman has  2, 878,747 followers, Daniel Tosh has 6.2 million followers on twitter. 

But it seems that people can be a little interested in science, if you can understand it, because if we look at the most popular scientific websites is that visits that are made to them are distributed as follows:
1. How stuff works?,  12,000,000! Clearly , it's good to know, n how everyday things work and if someone explains it and you enjoy this, perhaps it's easy to understand it!.
2 NOAA 10,000,000
3 Discovery Channel 9,400,000. What teacher has not heard: I saw it on Discovery Channel?.
4 NASA 8,900,000
5 Science direct 4,500,000
6 Science Daily 2,400,000
7 Nature 1,800,000
8 Treehuger 1,700,000
9 PopSci.com 1,400,000
10 Science Blogs 1,250,000
11 PhysOrg 1,200,000
12 New Scientist 1,000,000
13 Live 950,000 Science
14 Space 750,000
15 Network Orbit 600,000
It must be considered that these sites are not only reached in The United States, but if the world's population is estimated in 7 billion of persons, readings are reduced to very little, and one more comparison:  Lady Gaga has 27, 815 976 followers on twitter. Does this sound like she has more fans than Nature?.

But if we look again at the list, its possible to observe the level of complexity on scientific topics is inversely proportional to the audience, this means less complexity, more audience.

Why don’t people read nor understand science?

I learned many years ago there are three levels of science, basic science, where are those of highest level, sometimes in laboratories with expensive equipment, often trying to give answers to the most complex things in the universe. Between them and simple mortals, they are those who interpret those complex things and have the ability to explain them with simple words. Sometimes they are scientists, sometimes they have enough passion for some topics, but without their ability to explain in words what scientists write based on molecules or mathematical calculations, it would be difficult to understand much.

Finally there is the applied science, or those who take what the second level and put it in action. Sometimes they are mercenaries and science are expensive, but something to eat.

Many journalists and scientific bloggers are at the second level, sometimes communicate directly with scientists, although they can feel fear of scientists´ comments,  saying  simple mortals are wrong or they do not understand beyond few letters (this was Carl Zimmer's  comment of on twitter).

This is the reason why there are manual to argue with scientists as the written by Jacquelyn Gill, who explains that scientists only talk among themselves and only accepted evidence of writings that have been reviewed by peers, their peers. Even when if at some cases it has been proof that articles can be wrong or even based on false evidence. But it seems there is a tremendous competition between them and sometimes unfair. In some countries it makes sense, when the programs for science and Academy depends on limited budgets, and it is distributed among so many brilliant minds just few coins.

Gill explains that if an idea was written in a blog or in a magazine that does not have some credibility, it is simply disqualified by the experts. In addition, if simple mortals are not capable of understanding their language, means the end of any discussion. 

To this is added, as indicated by the numbers, the greater amount of scientific articles are written in English. So if you are not bilingual it can be difficult to read.

But I also learned ´many years ago to be skeptical; I was told that it was a peculiar quality to scientific minds, and which helps to look further than things appear in a first look. There are many examples in the history of science, but what I like the most it’s the apology that the New York Times newspaper, had to give Robert Goddard, who was accused of crazy to say that it was possible to build rockets, manned, powered by fuel, capable of reaching the moon. 

The community ridiculed him, and he had to wait 49 years for an apology. His idea was not only correct, but possible.

Another widespread thought is that the best ideas are written in certain magazines or do certain laboratory or academies. As if thinking were tied to a place, sometimes get me the impression they think only from 8 am to 6 pm and after that anything is futile. But for a simple mortal to write in those magazines or work at those places, need to work 5 times harder than any other and when the most important thing is eating, it is very easy to forget about the science. 

If I learned well, a knowledge or an idea is valid only if it is written by a name or a known magazine?, does perhaps no one else have the right to think?, and what if  such a blogger is a retired professor?, who cares, experts won’t ask more questions, they are busy doing science.

Is it possible to have a society that is literate in science?

The answer is complex, is needed an interested society and numbers indicate that doesn’t happen. But when we asked:  who is the most famous living scientist?, the first name in everyone's mind is Stephen Hawking. 

He has appeared in several popular TV shows (I mean with millions of viewers), for example his appearance on the Simpsons, in the chapter 22 of the tenth season, was watched only in The United States by an audience of 6.8 million viewers. Others know him for his appearance on South Park, and more recently in Big Bang Theory. I know between recognize his name to understand his theories there is considerable distance, but people recognize him, as Michael Phelps, Derek Jeter or Madonna. Only in Facebook  Dr Hawking has 209, 210 subscribers.

In a list released by a writer is said to have other four famous living scientists. We can or not agree with it, I would have on my personal list to David Eagleman, since I am interested in his ideas about the brain or Francis Crick because I am passionate about his work about the mind, and I could not miss Stanilas Dehaene, for his work with learning, but here there are the names of the original list and one of their lectures at TED:
1. James Watson TED http://www.Ted.com/talks/james_watson_on_how_he_discovered_dna.html 382 204 have seen this Video
2. Jane Goodall TED http://www.Ted.com/talks/jane_goodall_at_tedglobal_07.html has 204,047 views
This video has been viewed 743,076 times
4. James Hansen  http://www.Ted.com/talks/james_hansen_why_i_must_speak_out_about_climate_change.html This video has been viewed 491,350 times.
 
If we want a society educated in science, scientists should answer our foolish questions of their followers, they should be closer to politicians, journalists, comment in forums of ordinary people, remove the suit of arrogant and remember that one day they were normal people and they even ate popcorn while watched a science tv show. Long before Tivo.

Speaking of politicians, a year ago, during the economic crisis in the United States, I was scared reading and watching how political meetings were so long and they couldn’t find a solution to the dilemma. I could not resist and asked my husband and my father-in-law, if there are so many Nobel awards in economy at this country, why not one of them can resolve the situation?. Nobody could answer me.

I decided to write this note thanks to all articles and blogs about what teachers and politicians should know about science, in response to all and from my humble point of view. What should politicians know science?, simple, social life would be easier and economically it would add much in the short, medium and long term. 

What should scientists know about teachers,  politicians and  ordinary people?, beyond that we are objects of constant study, you must start the dialogue, or the distance between everybody  will be getting bigger.

Scientist should understand that politicians know nothing about science,they don't have to, but they allow the budgets to science programs. Is it worth talking to them and explain some of the advantages of science?.

Attempts to popularize science among the young are carried out, for example the idea of Google Science Fair, it brings together young people from all over the world scientists and the proposal of Scientific American reunite to 1000 scientists in 1000 days, that incredibly, has only brought together scientists 1552 so far, sounds very little if is considered the National Academy of science in the United States was founded in 1863 and now has 2,200 members and 400 foreign partners; the National Academy of engineering has 2,200 members more 200 foreign partners and the Institute of medicine has 1, 700 members and 100 foreign partners, and this is only the cream and cream of science in the United States.
But back to the original question:

Should teachers know of neuroscience?

I have said that there is a great distance between duty and wishing. Teachers must know from neuroscience as much as they want to, and apply both as the official educational programs allow them. Because we are always willing to say how to teach better, but we don't know what their programs indicate. Knowledge has to be purchased at an enormous speed, have to meet bureaucratic affairs, attending many children in a classroom, dealing with parents, educational authorities, and survive the traffic. Who are we to tell them how to teach?.

Because we scientists can have a lot of research about a  X neuron, but we have not been able to fully explain how the brain works. There is much information molecular, biochemical, electrical, neuroimaging, neuroanatomical, neural networks, we try to explain processes, but until now, no one raises the hand and says: works and thus learns. That's fascinating science, more studies, more question arise.

But teachers know something and very clear: Children learn when they want, how they want and what they want to, and not as plans and programs the Government and the international agencies indicate, or how neuroscientists are written in their expensive journals.

If scientists want to be heard, we must learn to listen and read each other, what  simple mortals say and think by, being in touch with journalist without making them feel that they do not know a letter, that it is true, they don't know what the expert knows, but they are trying to!. 

I think that if science touches the door of homes and offices of politicians, there will be fewer diseases, less resistance to treatments, greater acceptance of ideas that achieve progress for all, solve problems, yes I know, I'm idealistic.

Autism spectrum disorders: a detection of abilities and not dis-abilities.

I found once a quote which is supposed was written by Volkman and Cohen and it says: “If all individuals diagnosed with autism could be together in a room, the most striking fact would not be their similarity, but how different they are between them". And I would like to  add: and if at the same room we can  join all therapists and people who do not live with children with autism  every day, them it would be very easy to see what children cannot do, but only a few would be able to admire their skills.

I learned the word autism more than 20 years ago during my work in a children's hospital in Mexico. Those days, the diagnosis was confused with psychosis and not many persons spoke so publicly about the topic. The only therapeutic proposed was medications that maintain quiet to children and if at home behavior and socialization did not work, then the only one answer was a hospital. There were some behavioral therapies that were used with a few children, but the therapeutic goal was to keep them quiet.

Nobody spoke too much, at least in Mexico,  of other developmental disorders such as syndrome fragile X, Rett syndrome, the Prade Willi syndrome, childhood disintegrative disorder, tuberous sclerosis, Williams syndrome, Angelman's syndrome or Asperger's syndrome, and if anything was said something of the autism spectrum disorders, the only one word was autism.

In contrast, Autism Speaks is currently an international voice that gives help to autism children and families and their numbers reported that 1 in every 88 children has autism diagnosis at the United States. 

Certainly there is extensive information now. On the internet when someone types the word autism appear at least 9 860 000 results. But there is still something on the entire set of signs and symptoms that children have and that every parent knows so well. Something that every site, campaigned and paper, sometimes forget: we started to talk about autism and we forget the children and the people behind it. 

As experts we can’t hide our perplexity, because the autistic spectrum has a variety of features, even though they have tried to group into versions of the DSM and ICD, there is always a child that presents all the symptoms and none of the above.

At a conference held in the CISAME in 2010, once all the experts talked with passion about what each of us we have studied about the disorder, a girl of 8 years raised her hand. I think we all ignore it for a few moments, and it was not we did not see her, but there were more hands trying to ask those things we wanted to share, so she raised her hand higher, to the point that we all thought that she would jump on the person near to her to get our attention. We finally gave her the word and with reverence asked us: "why do you speak about autism?" before autism I am a girl when will you speak about children with a diagnosis of autism? ".

She was my motor and I started to write about what it’s possible, all the things any child can with or without  developmental disorders, the reason why so many  experts have sometimes spent a lifetime saying loud and strong things beyond the word autism, and even beyond all behaviors that have caused distress to the parents, or the moment when they receive the diagnosis, much more than the long list of No that parents and children here every day: they cannot talk, you cannot write, they cannot go to school, they  cannot dance, they  cannot go to College, they cannot make anybody smile, do not, do not not. 

Don’t they breathe?, perhaps don´t  they grow?, let’s go slowly.

Looking for evidence

More than 50 years ago was suspected that autism is linked to a specific gene. At least 17 candidate genes linked to the disorder to varying degrees and in different ways have been reported so far, he points to others who may have incomplete information or translocate. That's why there is more research with families who have more than one child with a diagnosis of autism, but so far, there is not a single research that points to a single gene.

Even those development disorders such as the fragile X or Rett syndrome, where there are a limited number of genes responsible for all the symptoms, can show variations in the development of the children and there were found mutations or genetic drafts that do not tie in all cases. That’s one reason why unique children can be found, children who have more skills than ICD show in its pages.

On the other hand, mirror neurons have been mentioned as responsible for the difficulties in socialization and empathy, however, some children "learn" to socialize depending on environmental conditions.

Vaccines were during some years claimed as responsible of autism, but it has already proven that they are not guilty of triggering, and even better all the story was an invention.

A new group of evidence show than the virus HHV-6 can be part of some cases, but there is only few articles about it.

And I can continue mentioning factors, from environmental, family, social, and even cultural, but no matter how much time you can take to try to explain the causes of autism spectrum disorders, the truth is that the great needremains to help children and their families to have a more happy life.

And following my passion about the brain and trying to find answers where the disorder originates, I began to look for answers, trying to see what everyone sees, that no one looks. 

All studies point out about all the neuro degenerative aspects and brain differences, particularly in the white matter, which are the nerve fibers, myelinated responsible for the transmission of information from one cell to another. Differences in the amount of gray matter that is the neural bodies and dendrites devoid of myelin have also noted. With this in mind, there is no doubt autism is a neural problem.

I’ll stop for a second to say that for many years researches know that the brain is plastic, moldable, flexible and it adapts to environmental emergencies. This feature is probably given by evolutionary aspects, what you have may change with the passage of the years. And although many generations are required to see a general shift to level species, if it is possible to see brain differences from various learning tools. 

In the case of normal development, even the brain does not know what kind of environment must adapt, the plasticity allows to babies to develop those skills that will be used in the environment. Those actions can make him or her feel happier, those that will be reinforced, to speak, walk, and smile. This usually this reminds me an old question: Is an artist born or made?. 

The answer that I like most is that perhaps all of us concert pianists, but we never had the opportunity to beat a piano.

For example, it’s known that even though children are able to recognize foreign languages, they will lose this ability to give priority to the native language, finally it is that is going to provide an effective socialization. This is clear that neurons survive depending on usage. 

It seems that nature has very clear use of resources and their exploitation, by what is not the luxury of having neurons which does not use, and will maximize those that serve as tools in response to the environment.

The brain with developmental disorders

Under this principle of plasticity, the idea is that the neurodegenerative process apparently happens even before the first symptoms, but to the passage of the cerebral arrangement, imprisons areas that are losing connections and that imprisonment, and eventually becomes little used. However, there are other areas that manage to survive and become efficient, much to its way.

If every child had deficiencies such as are indicated by the diagnosis books, it would be easy to diagnose the disorders, however, it seems to me that it is not. Even for experts, it is easy to confuse the symptoms. For example, in a study conducted in the Autism clinic of CISAME, in Mexico city, it was found that 27% of cases should not be diagnosed as part of the autistic spectrum, because the clinical histories revealed perinatal problems as causes of the symptoms and signs of children.

That’s why I prefer to invite parents to analyze: what children can do?. The main symptom is focused on the shortcomings of communication, but even in children who do not speak show means of expression. This is the case of Carly Feischmann, who had never said a word, until by chance, his parents and therapists discovered that she was able to write on a laptop and that opened the door to communication.

But, what else can your child do?, if you search you will find that your child can do things, not like the others, perhaps  he or she does things with a special nuance, perhaps so sophisticated as the protagonist of the series, Touch, or much to his or her own way. Even maybe she or she smiles with that expression of a few friends, but for you, without place to doubt is a smile.

On the basis of brain plasticity, don't give up, your child's brain will adapt to circumstances, perhaps slower and not as high, and rightly so as other children. But if support you, there is no doubt that surprise.

Perhaps the rule is not to see him with pity, that feeling of disability is destructive, it makes us think that you can't, you don't know, that not this and not the other. Try, do it twice, three, four. How the Olympic athletes get so amazing victories?, they do the same movement over and over again until they can  make it perfect. It’s worth the attempt.

Finally, would like to recall that no brain is equal to another, that all we learn, feel and see the world in different ways, that's why I do not understand, and I would admit my ignorance, I don't understand the why focuses attention on what children cannot be achieved, as if genetics or disorder destination, if there are many evidence of brain plasticity and achievements perhaps small for humanity, but who become great strides of each child with any developmental disorder. Despite the difficult thing is sometimes deal with their tantrums.

I think that scientist, parents, and society must work in the understanding of disorders, not to ask for money, not for gain notoriety or be at the front of the photo, but to give a chance for adaptation to children, who one day will grow and become adult.

The big mistake is to ask that society adapts to them, asks to parent to stop their lives to one side for the sake of their children. One day the parents won’t be around to look after that child, so the goal is adaptation and not the adequacy.

Skills

Without falling into the trap that all children are like the books, I can say that several researches find math skills, music, the visual Arts, as the most reported, but, have tried to give your child a computer or a tablet computer?, maybe help you at the garden?, maybe the macrame is a choice... those who have in addition a little or a lot of obsession compulsion can be excellent for quality control. 

I would say, don’t think in them as the persons who can do nothing, find that they can do, and you will find the talent. The goal is to find what they can do. Even the blind deaf child can feel and smell and that can be enough to discover the world.

And for those who have brothers, enforces the same. My goal in education is that children can find their talent as young as possible so they can be happy children and successful adults. Perhaps a skill as an adult is to find the gift of each one of these children. Achieve communication, by any way is worth. I'm sure you'll be amazed of what you can  find. 

Being a child with autism is not a diagnosis, it is a tag of life, but most importantly, YOU have a life to decide what to do with it. They just need someone who provides one hand to achieve this.
