Bertrand Russell’s Ten Commandments for Teacher


1. Do not feel absolutely certain of anything.

2. Do not think it worthwhile to proceed by concealing evidence, for the evidence is sure to come to light.

3. Never try to discourage thinking for you are sure to succeed.

4. When you meet with opposition, even if it should be from your husband or your children, endeavour to overcome it by argument and not by authority, for a victory dependent upon authority is unreal and illusory.

5. Have no respect for the authority of others, for there are always contrary authorities to be found.

6. Do not use power to suppress opinions you think pernicious, for if you do the opinions will suppress you.

7. Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric.

8. Find more pleasure in intelligent dissent than in passive agreement, for, if you value intelligence as you should, the former implies a deeper agreement than the latter.

9. Be scrupulously truthful, even if the truth is inconvenient, for it is more inconvenient when you try to conceal it.

10. Do not feel envious of the happiness of those who live in a fool’s paradise, for only a fool will think that it is happiness.

It has been a long time since I last posted – too long!


IMG_5504I  have been busy because I have decided to write a book on education.  My subject is research-based education and does it exist?  Here in Ontario we are big on research based or brain based education.  I am always a bit dubious about this as there are at least three things that need considering in implementing education based on research.

The first is the reliability of the research For readers like me who don’t always remember the difference between those two important pillars of good science, reliability and validity, I will explain.

Reliability refers to whether an experiment can be done more than once and by other researchers and still get the same result.  If your dog eats a tablespoon of peanut butter and then lies down and rolls over twice, can you get the same effect the next day when you feed him peanut butter?  If you can, can your friend in the next city get her dog of a different age to lie down and roll over twice after he has eaten a tablespoon of peanut butter?  Will it work with different breeds or only black dogs weighing more than 60 lb.?   The more often replications of the experiment end up with the same result, the more likely it is to be reliable.

The second pillar of research is validity.  This is not as simple a concept to explain.  Validity requires that the thesis and experiment make sense i.e. they are designed using both logic and fact.  The conclusions must be interpreted logically, too.  As the saying goes: “data is not the plural of anecdote.”

One mistake we often make is confusing correlation and causation: a classic example is the woman who believed that it was the sign “deer crossing” that caused deer to cross at that particular spot on the road.  She thought this was very dangerous as she had hit a deer three times just after passing the spot.  Her solution was to move the crossing.

The mistake this woman made was to mistake the correlation of a deer crossing sign and the deer crossing the road with the sign causing the deer to cross the road.   Some careful thinking about the nature of deer and their abilities would have brought the realisation that deer can’t read or follow traffic rules.  The deer’s preference for crossing the road at that point was the reason the sign was posted, not the other way around.

We can laugh at this person’s logic, but how often do we see similar thinking in

World Health Organization building from the So...

our lives.  Think of your friend who won’t get her child vaccinated because she believes that vaccinations kill children.  The World Health Organization (WHO)

clearly outlines the faulty logic as it applies to the DPT i.e. Diphtheria, pertussis (whooping-cough) and polio:

Diphtheria-Tetanus-Pertussis (DTP) Vaccine And Sudden Infant Death Syndrome (SIDS)

One myth that won’t seem to go away is that DTP vaccine causes sudden infant death syndrome (SIDS). This belief came about because a moderate proportion of children who die of SIDS have recently been vaccinated with DTP; on the surface, this seems to point toward a causal connection. This logic is faulty however; you might as well say that eating bread causes car crashes, since most drivers who crash their cars could probably be shown to have eaten bread within the past 24 hours.

If you consider that most SIDS deaths occur during the age range when three shots of DTP are given, you would expect DTP shots to precede a fair number of SIDS deaths simply by chance. In fact, when a number of well-controlled studies were conducted during the 1980s, the investigators found, nearly unanimously, that the number of SIDS deaths temporally associated with DTP vaccination was within the range expected to occur by chance. In other words, the SIDS deaths would have occurred even if no vaccinations had been given.

In fact, in several of the studies, children who had recently received a DTP shot were less likely to get SIDS. The Institute of Medicine reported that “all controlled studies that have compared immunized versus non-immunized children have found either no association . . . or a decreased risk . . . of SIDS among immunized children” and concluded that “the evidence does not indicate a causal relation between [DTP] vaccine and SIDS.”

Looking at risk alone is not enough however – you must always look at both risks and benefits. Even one serious adverse effect in a million doses of vaccine cannot be justified if there is no benefit from the vaccination. If there were no vaccines, there would be many more cases of disease, and along with them, more serious side effects and more deaths. For example, according to an analysis of the benefit and risk of DTP immunization, if there was no immunization program in the United States, pertussis cases could increase 71-fold and deaths due to pertussis could increase four-fold. Comparing the risk from disease with the risk from the vaccines can give us an idea of the benefits we get from vaccinating our children.

For more information on vaccines and childhood illnesses go to Global Vaccine Safety:

Six common misconceptions about immunization.  This is a much more serious case of correlation = causation than the Deer Lady’s confusion.

The sample used should be a reasonable size and reflect the population in question.  How many samples, people, classrooms or animals are needed can’t be defined theoretically, but scientists and most sensible people should know when the sample is not enough.   For example if one wants to know the death rate from measles, the best sample would be all the reported cases of measles in an area or all the confirmed cases of measles.  The latter would be better, unless one can safely assume that doctors are generally accurate in diagnosing measles and therefore their reports won’t skew the data.

One of the cruellest results of poor research is the myth that the MMR (mumps, measles and rubella) vaccine causes autism .  The research was published in 1988 and retracted by the eminent medical journal, Lancet in 2012.  Not only was the research retracted but the author was also reprimanded by Britain’s General Medical Council and stripped of the right to practice medicine in Britain.

The doctor used only 12 children for his research, taking the blood samples from children at his son’s birthday party.  There were other flaws in his work; for more information see the sites below.

After his results were published in 1988, some British parents refused to get their children immunized with the MMR vaccine and the incidence of all three diseases increased.  Measles is highly contagious and can lead to more serious illnesses or death.  For example: one in twenty will develop pneumonia (a common cause of death from measles) and one in a thousand will develop encephalitis, putting them at risk for convulsions, deafness, mental retardation or death.  By 2008 there were enough measles cases in Britain to declare it an epidemic.  See web sites in the bibliography below for a discussion of MMR vaccination from at least two opposing perspectives.

Even when research is well done, there are two more pits for the unwary: drawing conclusions and applying the results correctly. If your dog rolls over repeatedly after eating peanut butter, is it to please you in order to get more peanut butter or does peanut butter put his belly in such agony that he needs to roll over more than once to relieve it?  One might argue that the dog’s motivation doesn’t matter; the important thing is that the dog rolls over.  It does, however, make a difference to dogs and to dog lovers.  They care whether pain or delight is causing the new tricks.  This is another case where the researcher will have to explore the connection between the incidents in order to do good science.

Research intent on testing the results of other studies is not glamorous and doesn’t get the headlines (or the grants, sometimes) but it is as important as the initial work.  In fact, without it, we would have more drugs with disastrous side effects, more collapsing structures and poorer educational systems.

The third thing that needs considering, besides reliability and validity and the conclusions draw by the researcher, is the interpretation of research by the layman – or woman.  It is easy to misunderstand research if we don’t read the work or summaries without a critical eye.  I find myself increasingly wondering who did the original research, how valid and reliable it was, if the researcher had a bias towards the results and what other research has been done. Education needs good research to inform good teaching practices and teachers need to know how to read the research, question it and implement what has been learned.

I have not covered everything you need to know about scientific methods and the methods of science.  My intention here is to draw attention to the layman’s need to understand scientific thinking and reflect critically on research before applying it in the field.  For a more thorough analysis, go to:  The Scientific Method vs. Real Science at http://www.av8n.com/physics/scientific-methods.htm.  It does require some thoughtful reading but it is worth the effort.

So, I am writing a book about the relationship between education and what we really know about the brain and relevant psychology.  I am still in the research stage.  Instead of doing my own original research, I am reviewing other peoples’ studies to understand the results and their relevance to education.

My blog will probably have a different flavour, as it is likely to reflect my thoughts and discoveries as I learn.  I hope you enjoy accompanying me on this journey.

When zero is not allowed, what is the difference between a student who doesn’t do assignments and a student who is on an Individual Education Program?


It is common to accommodate a student on an Individual Education Plan due to a disability either intellectual or physical, by reducing her workload if that is appropriate.  For example, an English teacher might require a student to answer one of two questions as thoroughly as every one else in the class.  For the second question he might jot down a few words to remind him of his thoughts on a possible answer, if he had time.  He will meet requirements of the assignment by thinking about both questions, but reducing the amount of writing required would accommodate his dysgraphia.

I should add that there are many other forms of accommodation.  Shortening the amount of work is only one but sometimes a useful one.

Gifted students on an IEP may have the number of questions they do for math practice reduced as they do not need as many to cement the concept.  Instead, the teacher may assign problems that take them farther into the concept.

You can see where this is leading.  What a teacher assigns and the amount she assigns is tied in to how much work she believes is needed to learn the material.  If you have read my four posts “How do you get to Carnegie Hall?” you will remember that repetition AKA practice is necessary for learning skills.

If a student is not on an IEP, does a teacher have a moral right to change the program he used his expertise, experience and professional judgement to design just to accommodate a normal student who hasn’t handed in some assignments?

Consistently not doing work is a behaviour problem and those who are best equipped to deal with them should be informed: parents, guidance counsellors, principals, vice principals.  In the meantime, teachers should be allowed to get on with what they were trained to do.  And that includes assessment

Do we really want our future doctor, lawyer, builder of bridges, electrician or plumber accepted to train in their professions even though they had missed parts of their math or physics or English classes?  If they find zeroes discouraging, let them ask for help.  If they don’t want to learn enough to ask for help, please don’t lie to the public by indicating they have actually passed a course.

Announcing a new blog: for Teaching Outside the Box


http://teachingideasoutsidethebox.wordpress.com/

The new blog is intended to be an adjunct to this one. While this blog is largely a commentary on education, the new blog will offer practical information. In a few months I will be retiring from formal teaching within a school board but I can’t stop spilling over with ideas for teaching. Rather than leave them to simmer, I will be posting them there. I will also post some of my favorite ideas from the past 25 to 30 years of teaching.

There will rarely be fully fledged lessons or units, nor will they be necessarily specific to a grade. I have adapted grade twelve units to be used in a grade eight class and seen those units adapted to use in a grade five class. Sometimes they will be a full lesson or a full unit or a cross subjects lesson. Whatever they are, I do ask you to give me credit on any written document.

Why won’t they be fully fledged? To be frank, I have never taken a lesson and done it just as it was written, even if I created it and used it satisfactorily the year before. There are always too many new factors such as new information, a crossover from another subject, the class’s interest, different time limits and I am sure you can add to that list. I also got bored doing the same thing twice in exactly the same way.

If you want help adapting or designing anything I post, especially if it is meant for gifted or other IPRC’d students, I would be happy to come and work with you if your school is within an easy distance of Ottawa or Toronto. I am also on Skype and on Skype, I can consult even if you are on the other side of the earth.

What can I help you with? I have taught every grade from two to eight (ages 8 to 13) and as a supply teacher, I taught everything. I have taught adults and I am a qualified teacher of English as a Second Language. I am a specialist in teaching children with special needs, especially gifted and learning disabled. I hold a masters in adaptive education. The best fun I have ever had in education, besides teaching itself, was having student teachers in my classrooms. I loved encouraging them to try new things and watching them grow in confidence.

So, if I can help, let me know.

Not Something of which I Want Reminding


My only comment now is that I have been here and I am deeply upset that this kind of thing continues to happen.  As a link to this CBC article will probably eventually disappear, I am going to copy the whole article here.

Falsely accused teacher calls for accountability

Accused of abusing students, teacher spent weeks under suspicion

An Ontario substitute teacher who was cleared of abuse allegations is speaking out, suggesting that parents and students be held accountable for making false accusations.

“Something is terribly wrong here,” said Susan Dowell, who has taught school for 15 years. “Children who do make false allegations – parents who make false allegations – what happens to them in the end?”

The complaint against Dowell came after she told a grade five boy not to throw away an uneaten banana at lunch. Dowell was on lunch room duty, during a one-day teaching assignment at R.L. Graham elementary school, in Keswick, Ont.

“I told him to eat it…or put it back in his lunch box and take it home. His parents paid good money for fruit like that for him to eat,” said Dowell.

Dowell said the boy went home that night and complained, so one of his parents went to the school vice principal.

“The story that the parent heard and later told the administration…is that I had him go into the garbage to take out a squishy banana — eat garbage basically — and humiliated him in front of his friends.”

Dowell said the incident happened right after she had enforced classroom rules, for a group of unruly students – the boy’s friends – that morning.

“They came in with an attitude immediately…like they’re going to see how far they can go,” said Dowell. “I know enough, in a situation like this, I’m not going to get into a battle with students…so I asked them to go to the office immediately.”

Banana incident sparked investigation

The following week, while teaching at another school, she was suddenly sent home and told she was under investigation by Ontario’s Children’s Aid Society.

“I was just shocked and confused,” said Dowell. For over a week, she said, no one would tell her what she was accused of doing.

“For nine days. It feels like you’re waiting to find out a diagnosis with cancer. It’s crazy making…I was told not to speak to anyone.”

Dowell later learned that after the parent complained about the banana incident, the vice principal talked to the other students she taught that day. She said the group of unruly students she’d sent to the office had plenty of complaints.

Dowell was on a one-day teaching assignment at R.L. Graham Elementary School, when the incidents happened.Dowell was on a one-day teaching assignment at R.L. Graham Elementary School, when the incidents happened. (CBC)“Somehow all these children came up with all these incredible stories of how I had grabbed their wrists and I left red marks that apparently weren’t showing later,” said Dowell.

“Children are getting a lot more savvy these days. It used to be, ‘make the occasional [substitute] teacher cry.’ Now they know they can have you suspended.”

Without talking to Dowell, the school immediately called the Children’s Aid Society, which it is required to do by law, when there is an allegation of abuse.

“I thought I’d be treated as a professional colleague and I’d be given the benefit of the doubt and at least gotten a phone call afterwards to ask what had happened, from my perspective.”

Told to expect police

Dowell was removed from the board’s substitute teacher roster. Her union told her she might even be arrested.

“You are told police could come to your door any moment. What do you tell your family and friends? It’s a horrible situation to be in, knowing that you’re totally innocent,” said Dowell. “I knew I had never been alone with a child. I never put my hands on a child…but it felt like I was guilty until proven innocent.”

Dowell spent a month at home on partial pay, borrowing money to pay her bills, before the CAS concluded the allegation was unfounded.

The Children's Aid Society concluded the complaints against Dowell were unsubstantiated.The Children’s Aid Society concluded the complaints against Dowell were unsubstantiated.(CBC)“The Society…has determined that Ms. Dowell did not use excessive physical force with the students in her class or intentionally embarrass the student during her interactions with him in the lunchroom,” read a letter to Dowell’s lawyer from the York Region Children’s Aid Society.

“The Society is not substantiating any concerns related to the alleged use of physical force or public humiliation by Ms. Dowell, nor would the Society be concerned should Ms. Dowell return to her occasional teaching position.”

Dowell was then allowed to go back to work, but she still faces a probe by the school board, which is standard protocol when a complaint is made.

“These are separate investigations with different standards,” said Christina Choo-Hum of the York Regional School Board. “We have a much closer eye and more detailed approach to our investigation.”

Due diligence

When asked why a minor incident would lead to a full-blown investigation, Choo-Hum said, “If there is the slightest question [about a teacher] we err on the side of caution. It’s due diligence.”

Choo-Hum said no one from the school or the board would comment on Dowell’s case, because it’s a personnel matter. She said the board does not keep statistics on how many complaints against teachers it investigates, or what the outcome is.

Nadia Ciacci, president of the union representing 1800 occasional teachers in the York district, said she’s seen false complaints multiply every year, from none three years ago, to eight this school year. Ciacci said all were unfounded.

The message has to get out there – that this has to stop.”

Jon Bradley, associate professor of education at McGill University, has studied false allegations against teachers. He knows one case where the teacher committed suicide. He said careers and lives are ruined, particularly for men falsely accused of sex abuse.

“It’s really a mess,” he said. “We seem to be almost afraid. We seem to be saying – if a kid makes an accusation it must be true. Kids don’t lie. That’s the first thing we say – kids don’t lie.”

He cited one case that should have been suspect from the start, because of how the nine-year-old girl characterized what happened.

“She said ‘he leered at me suggestively.’ I don’t know how many grade four students would use an expression like that.”

No consequence for accusers

He said parents and children involved in false allegations don’t face any consequences, and they should.

“What’s really sad in this is we’ve got adolescents making terrible accusations against teachers and getting off scot-free with absolutely no penalty whatsoever,” said Bradley.

Ciacci of the teacher’s union said she would like to see parents held legally responsible, perhaps through an amendment to Ontario’s Parental Responsibility Act.

“Look at the cost to taxpayers as well for the Children’s Aid involvement,” she said. “Parents need to be held accountable.”

Dowell said the group of Grade 5 students misbehaved and challenged her in class, then claimed she had abused them.Dowell said the group of Grade 5 students misbehaved and challenged her in class, then claimed she had abused them.(CBC)Choo-Hum said there is no school board policy or standards for dealing with students who make false allegations.

“Students are dealt with on a case-by-case basis [at the school level],” said Choo-Hum.

Dowell said she is confident the board investigation will also find she did nothing wrong. Regardless, though, she said she will never feel the same in the classroom.

“The next time I see a kid throw out a banana I am obviously not going to say anything. And next time I see belligerent, defiant behaviour – am I to turn the other cheek?” said Dowell.

““I feel very much I am damned if I do I am damned if I don’t.”
