What’s Wrong with Traditional Education

Alison Gopnik points out the people first start to learn by exploration (the same way scientists do), and then learn to do things well by apprenticeship.

When we actually start to look at the fundamentals, it seems children learn by exploring—by experimenting, playing, drawing inferences …. that kind of exploratory learning isn’t just the purview of scientists but seems to be very, very basic. …The other kind of learning that we see, not so much in preschoolers but in school-age children, is what I call guided apprenticeship learning, where you’re not just exploring and finding out new things but learning to perform a skill particularly well.

— Alison Gopnik in Fillion (2011): In conversation: Alison Gopnik in MacLeans.

Kate Fillion’s great interview with Gopnik, a cognitive scientist, is worth the read.

The traditional way of thinking about learning at a university is: there’s somebody who’s a teacher, who actually has some amount of knowledge, and their job is figuring out a way of communicating that knowledge. That’s literally a medieval model; it comes from the days when there weren’t a lot of printed books around, so someone read the book and explained it to everybody else. That’s our model for what university education, and for that matter high school education, ought to be like. It’s not a model that anybody’s ever found any independent evidence for. [my emphasis]

Update

EV, in the comments, recommends Allison Gopnik’s TED talk. It focuses on babies, but is a pretty good presentation.

Facilitating Movement in the Classroom

… the part of the brain that processes movement is the same part of the brain that processes learning.

— Jensen (2005): Movement and Learning in Teaching with the Brain in Mind.

I’m setting up a new classroom this year. How it’s arranged is very important to me. Montessori classrooms are designed for open movement and having different things going on in different places at the same time. Unlike last year, I won’t have to manage the entire middle school in the same room for the entire day. Instead, middle and high-school students will come in for two-hour periods for math and science.

Two hours is a long time for anyone, so I don’t expect them to be able to sit still for the entire period. In fact, just like in last year’s middle school classroom, I intend that the class devolve into smaller groups for most of that time. Students will need to be able to move around freely and associate freely, so long as they respect each others ability to work. I’m trying to arrange the room to facilitate that.

So how to arrange the furniture?

I need open spaces for students to walk and move. Eric Jensen has an entire chapter of Teaching with the Brain in Mind dedicated to how important movement is to learning. His focus is primarily on the need to save time for recesses and PE in increasingly regimented school days, but he also talks about integrating movement into everyday learning: energizers to wake kids up; stretching for more oxygen; and so on. I certainly know that I do a lot of pacing when I’m trying to think.

David Walsh also sees movement in the classroom as particularly important for boys.

Adolescent boys can have five to seven surges of testosterone every day. … And because testosterone is geared towards quick release, adolescent boys are prone to follow any impulse that might release stress. [p. 62]

…

Some experts think that making students sit still at a desk all day isn’t good for either sex, but girls are better able to tolerate it. Boys are more likely to get frustrated by school and loose interest. [p. 100]

— Walsh (2004): Why Do They Act That Way.

So no rows of desks. Instead, I’ve tried to make different work areas.

  • There’s one big area with a set of tables along three sides of a rectangle facing the whiteboard; students can be inside or outside of the rectangle depending on their needs.
  • Another area is centered around the couch, which may seem highly desirable, but I’ll be curious to see how they use it to work.
  • Toward the back of the room, there’s a solitary, larger-than-normal desk for a larger group that need space from the big set of tables.
  • I also have a smaller table near the window, that I envision would appeal to smaller, quieter groups, or even individuals sharing the same table.
  • And, finally, there is a bank of individual work spaces along the back wall.

That’s the plan, anyway. Classes have not started yet, so we’ll see how it holds up when it meets the enemy students. I am always happy to let them rearrange things, but most often they don’t seem to want to spend the time and effort.

WEIRD behavior

San foragers of the Kalahari would probably look at these two red lines and say they were the same length. (Image adapted from Fibonacci on Wikipedia)

The small window into the effects of modern life on the way we think was opened just a little wider recently by an interesting article by Joseph Heinrich and others. They sift through a large number of studies of people living the industrialized life and their more rural counterparts to find real differences in they way these different groups think.

San village

In the image above, the San foragers would be right, the two lines are the same length, but your typical Western, Educated, Industrialized, Rich, and Democratic (WEIRD) person would need to the left line to be about 20% longer for them to say they were identical. Why this is, I can’t say, but it might be that our visual perception is colored at an early age by the carpentered edges we see around us. Or maybe not.

And it’s not just in vision. WEIRD people think of fairness and co-operation in decision-making, and where things are relative to the self differently too, and their kids tend not to be able to identify easily with other species. The latter result is likely because of the “nature deficit“. The article clearly demonstrates that people think very differently, in very fundamental ways, if they come from modern environments.

The paper, found via Big Questions Online and Edge, is a fascinating read, and not too bad coming from a technical journal. There are a lot of interesting results summarizing a lot of behavioral science research. As a reminder to remember that one scientific article, no matter how good it is, remains just one perspective. the paper’s pdf has a number of commentaries and criticisms attached from other behavioral science researchers.

What I’m still trying to process, are the implications for Montessori educational philosophy. Because there are these significant, large differences in the way people see the world, we need to be aware of the perspectives of our audience. Students also need to appreciate how cultural differences affect the way we think and see the world that influence how we argue and how we behave. Yet they also need to recognize the there are some subjects, say the physical sciences, that are objective; there is a single, definite truth (for some value of definite) about the composition of a water molecule.

To teach effectively, you need to speak the same language

An interesting research project has shown that the same parts of the brain light up when you’re telling a story as when you’re listening to the story. So much so, that you begin to anticipate and parts of the your brain actually light up before the same parts in the storyteller’s. And the greater the synchronization, the greater the recall of the story.

The researchers found considerable synchronization between Silbert’s brain-activation patterns and those of her listeners as the story unfolded. For example, as Silbert spoke about her prom experience, the same areas lit up in her brain as in the brains of her listeners. In most brain regions, the activation pattern in the listeners’ brains came a few seconds after that seen in Silbert’s brain. But a few brain areas, including one in the frontal lobe, actually lit up before Silbert’s, perhaps representing listeners’ anticipating what she was going to say next, the team says. – Balter, 2010

That’s fascinating enough, but the control of their experiment was to have listeners listen to a story in a language they did not know. There was not the same synchronization. This means, if we extrapolate a little, that the amount of language comprehension determines how much you learn from a conversation, or hearing a story, or listening to a lecture, or even for understanding a set of oral instructions.

So if you want students to remember something you need to speak in their language. Language here refers not just to English versus Russian or whatever, but speaking using common idioms that the student is, like, you know, familiar with.

What Video Games Have to Teach Us about Learning and Literacy, by James Paul Gee

James Paul Gee has written a lot about this type of communication, and what it means for learning. He argues that meaning is situated, that is, how we understand something that is said to us depends a lot on our previous history and experiences. The most effective communication only really occurs within communities that have shared the same, or similar, experiences.

We are as teachers, of course, trying to expand student’s ability to use language, and introduce them to the language of different communities. But we should probably pay attention to how we speak in different contexts, and speak in their language when we want them to really remember something.

Stress, pressure and performance

How well does extrinsic motivation help us perform? NPR recently had another interesting interview with Dan Ariely where he talked about how rewards, cash bonuses in this case, affect performance.

It turns out that while bonuses increase people’s desire to perform better, people actually perform worse, probably because of the increased stress.

Jonah Lehrer actually suggests that this also applies to negative rewards. He suggests the engineers trying to cap the oil leaking beneath the Gulf of Mexico should take more time off because pressure from powerful incentives reduces our ability to think creatively.

So think about what this implies for high-stakes testing.
