5 little monkeys

At Edcamp Delta, Brad shared the following parable with me.

In the parable, researchers supposedly put 5 monkeys together in a cage, and in the cage there were some steps leading to some bananas. Whenever any of the monkeys would start to go up the steps to get a banana however, the hypothetical researchers would spray all of the monkeys in the cage with cold water. Every time any one of the monkeys went to get a banana, the entire group would get sprayed with cold water. After time, the monkeys would self-regulate and would attack any monkey that tried to make a move for the bananas, and the researchers stopped spraying the monkeys with water.

In the next stage of the experiment, they removed one of the original monkeys, and replaced it with a new one. The new monkey, not knowing about the cold water, would eventually decide to make an attempt to get one of the bananas, at which point the other four monkeys would attack the new monkey, preventing it from getting a banana. Over time, the new monkey learned not to make an effort to get a banana, and even though it had not experienced the spraying of cold water, it learned about the aversion to going to get a banana.

Over time, the researchers replaced each of the original monkeys with a new monkey, and each time, the new monkey learned not to attempt to get a banana as the other monkeys would beat it up. In other words, the researchers learned that the monkeys had passed along a cultural adaptation (avoidance of getting bananas) without having the original reason for the adaptation still present.

There was an experiment done with monkeys in the 1960s which is likely from where this parable was derived. Stephenson was able to train monkeys to avoid touching an object with blasts of air, and discovered that these monkeys could transmit this aversion to a ‘naive’ colleague (Stephenson, 1967). So while the parable seems to have never actually been tested, the results from Stephenson’s experiment suggest the parable is believable.

The point of this parable is that we can often repeat patterns as a form of peer pressure without understanding the original reasons for the behaviour. While we have an advantage over monkeys, which is that we can clearly articulate to each successive generation the reasons for a particular action that we take, unfortunately, we often do not share our reasons with the next generation, and only share the rules that we have established.

We see this experimented repeated over and over again in society. For example, suppose that in a subway station a door was locked in the early morning, and another door was unlocked. The first people to arrive at the subway station, not seeing anyone around, will test both doors, and enter through the one that works. Eventually traffiic gets a bit higher, and the door that works is always open because of constant traffic through the door. The other door, which doesn’t work, is assumed to not work since no one seems to be using it. If a custodian came by and unlocked the door, it wouldn’t be used, until someone came and actually went against the grain and tested the other door. We could call this person who tests the other door, even though no one else seems to be using it, an innovator.

Cultural pressure to follow what we’ve always done before, without really understanding the reasons why we follow the actions we do, is quite strong. How many of our structures in schools are done in certain ways even though the restrictions on doing them in other ways no longer exist?

I could use some help

I’ve been invited to do a keynote on the topic of educational technology for the University of Alberta at their Technology Fair for their student teachers and education faculty on February 13th. See http://www.educ.ualberta.ca/technologyfair/ for details on this conference.

I’m working on the keynote, and I could use some feedback. There are aspects of what I’ve written that I’m happy with, and others that I think need improvement. I’m not planning on reading this verbatim, but it will inform how I construct my slides, and speaking notes for the keynote. If anyone can give me some feedback, that would be greatly appreciated.

You can either comment on the keynote directly, or leave me a comment here. Thank you in advance for your assistance.

 

 

Are teachers overpaid?

Two authors of a controversial paper from the Heritage Foundation suggest that teachers are overpaid for their efforts. Here is my response.

The US economy dropped by 15.6% in 2009 for a total loss of $2, 342, 400, 000, 000. The people responsible for this disaster to the economy almost all received million dollar bonuses for their efforts.

From this I can deduce that the relationship between compensation for one’s "work" and what one does, or knows how to do, is not as straight forward as the authors of this paper claim.

All compensation is political. We choose to compensate some people differently than others for historical reasons, for political reasons, and obviously for economic reasons, but to ignore the historical and political aspects of compensation is to make a grave error in one’s research.

Thoughts? Do you think teachers are overpaid?

 

 

Is my son a writer?

This is a list my son created of things he wanted to make sure he got done for the day.

Writing a list

 

Does this make my son a writer? Is it more important that he is attempting to use text to get out his thoughts? Or is it more important that I help him correct the mistakes that he has made to make him a ‘better’ writer?

I’m of the opinion, at least at this stage, that we allow our son to make mistakes without being overly concerned about correcting them. Once he learns how to read, he will naturally learn how to spell better, and he will also learn more of the rules about how we write things down. At this stage grammar, and structure are somewhat unimportant, and just being willing to experiment and make an attempt is of critical importance.

What do you think?

Bicycling with my son


One of the first times my son rode his bicycle.


I went bicycling with my five year old son yesterday with his new bicycle from his Birthday. We haven’t had much of a chance to bicycle recently together, so my son hadn’t actually ridden his bicycle since the summertime. As a result, he had really forgotten a lot about what he learned over the summer about riding bicycles, and was really struggling to even get his bicycle going.

As the minutes wore on, he became more and more frustrated, although I was encouraged by his willingness to fall down and then get right back up over and over again. I did give him some advice and encouragement during this time, but since I knew he was capable of riding his bicycle, I didn’t want to be too helpful.

I realized that he had forgotten what it felt like to ride his bicycle. He was on an unfamiliar bike that was just a wee bit too large for him, and just couldn’t seem to get it together.

So I asked him to pause for a second, and get off his bicycle. I knelt, and we were face to face, and I asked him if he remembered riding his bicycle before. He said he couldn’t and his face fell a bit. I asked him if he remembered riding it down Auntie Juniper’s driveway (which is where he first learned how to ride his bicycle), and his face lit up while he nodded vigorously. I asked him to close his eyes, and imagine himself riding down Auntie Juniper’s driveway. He closed his eyes and I reminded him of how much practice he had put in, how much fun he had during the summer, and how good he had gotten at riding his bicycle. We spent about two minutes remembering together the feeling of the first time he rode a bicycle.

Right after that, he got back on his bicycle and started to ride it. He only fell down one more time while riding his bicycle, and even managed to ride it all the way around the park twice without stopping (he was pretty proud of this accomplishment). He went from unable to get his bicycle going more than a couple of feet to being as capable as he was during the summer after all of his practice.

This incident reminded me of a few things about learning:

  • What you know how to do is tied to your emotions. It is not enough to simply know things, you have to have some feelings attached to those things for them to be useful. When my son lacked confidence, he wasn’t able to ride his bicycle. When he regained his confidence, and remembered the joy he felt riding his bicycle during the summer, all of his knowledge about how to ride a bicycle came back to him.
     
  • Focused and contextualized practice are important in learning. You can’t really get better at riding a bicycle by talking about riding a bicycle, you have to do it. My son spent many hours riding his bicycle in order to become better at it.

    Although I see the obvious value in learning in practicing, I want to re-iterate how important it is that this practice be in a meaningful context. I often see comments on stories about mathematics education, for example, where the people talk about this or that cashier who was unable to make change without a calculator and how this points to an obviously sorry state of mathematics education. The question I want to ask in response to the often repeated story of the cashier is, when did they practice making change? They practiced arithmetic repeatedly in schools, no doubt, but how many schools have students play the part of cashiers and make change for pretend customers? How often is the skill of arithmetic practiced in context?
     

  • Practice should be part of a shared experience, and should have a positive emotion attached to it. If my son had learned how to ride a bicycle on his own, I wouldn’t have been able to help him remember his previous experience. If he had spent his entire time practicing in frustration or in anger during the summer, I doubt he would have remembered how to ride his bicycle yesterday.
