Learning science

al-Hassan Ibn al-Haytham (b. 965-1039) (Image from Wikipedia)

Science is, at its core, hypothesis testing. To learn science learn the scientific method: figure out the precise question to solve (as best you can); come up with an answer you think might work (hypothesis); test it; and repeat as necessary while modifying the hypothesis. Almost all science experiments for middle school through college involve following a set of instructions in the lab manual. Only in independent research projects do students actually go through the scientific process and then it’s difficult because they don’t have the experience.

Part of the problem is that it takes time. Time to muddle through the though process of trying to figure out what exactly is a tractable question to solve. Time to come up to with a reasonable, testable hypothesis. Time to figure out how to test it. Time for iterating through the process again, although, once you’ve set up your experiment the first time doing it again and again is not that hard or time-consuming.

With our Montessori Middle School’s six-week cycle of work, and even with the two weeks dedicated to the Natural World, students should be possible to get through this process for at least one problem. They would probably have to dedicate the two weeks to a single problem/experiment and it would probably be terribly slow in the beginning.

To discover the truth about nature, Ibn a-Haitham reasoned, one had to eliminate human opinion and allow the universe to speak for itself through physical experiments. “The seeker after truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them,” the first scientist wrote, “but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration.” – Steffens (2008) (Ibn Al-Haytham: First Scientist)

Montessorian on the web: Dr. Sarah Baird

Sarah Baird, from the Sea Pines Montessori Academy‘s Middle School, has recently started posting articles on K-12 education at Savannah K-12 Examiner. Dr. Baird was a research scientist (chemistry) before getting into Montessori so she’s not afraid to delve into the scientific literature to support her articles, yet her writing is targeted to a general audience.

“I am doing it to write (because I love it) and educate teachers and parents outside Montessori about our philosophy…. I feel like Montessorians keep all the info to themselves. We need to share and be proud to even have a little positive impact on our public schools,” Sarah Baird (2010) personal communication.

Having been blogging here for a few months I can say I greatly appreciate this sentiment, especially since one of the things I’ve been most impressed about with the Montessori approach is how it encapsulates so much of the modern pedagogy about constructivist education.

Score one for adding another intelligent voice with a Montessori perspective to the web.

Daydreaming …

Focused work. We like to see our students focused on their work and we give them long blocks of time to do so. It is hard, however, for anyone to stay on task for two hours straight. You have to allow for a certain amount of mind wandering and daydreaming. What a lot of neurologic research is uncovering is that zoning-out is an essential part of putting the pieces together and helps with learning.

When we are no longer even aware that our minds are wandering, we may be able to think most deeply about the big picture. – Zimmer (2010)

Daydreaming by Edward Harrison May (1876) (from Wikimedia Commons).

While we sleep the brain assembles information into coherent patterns, helping us learn and process emotions. Carl Zimmer has an article in Discover Magazine on how unfocused daydreaming accomplishes the same thing.

Intrinsic motivation in the real world

rewards tend to focus the brain more narrowly on the specific task that earns the rewards—thus making it harder to encourage employees to develop creative, innovative solutions. – Laura Vanderkam (2010)

Drive: The Surprising Truth about What Motivates Us by Daniel Pink

How do you motivate people in the creative economy? Apparently not with bonuses. The best way to get people to be creative is to motivate them in ways that “takes the issue of money off the table, so they can focus on the work itself” according to Daniel Pink in his book “Drive: The Surprising Truth About What Motivates Us.” Laura Vanderkam’s (2010) review of the book in the City Journal provides an excellent overview.

… leaders create an environment where people want to do their best. This involves giving people lots of autonomy over their time, their tasks, their techniques, and their teams; providing them an opportunity to work toward mastery of their professional craft; and imbuing their work with a sense of purpose. Laura Vanderkam (2010)

And translated into education Pink advocates the same approach as Montessori,

encourage mastery by allowing children to spend as long as they’d like and to go as deep as they desire on the topics that interest them. – Pink (2010)

It’s good to be reminded of the importance of intrinsic motivation every now and then. There are always forces, most often subtle but sometimes not, that push toward making sure students do well in the standardized tests and cover everything in the curriculum. High schools want to see good grades in all the subjects.

But what if a student just wants to write, and they just pour their heart into it. The other subjects suffer, especially the least interesting ones, but my goodness how their writing improves. What then? …

Praise and rewards

Looking through the Greater Good Science Center‘s blog post on how to raise kind children, I was struck, as I usually am, by the somewhat counter-intuitive finding that we should not reward good behavior (helping in this instance).

Very young children who receive material rewards for helping others become less likely to help in the future compared with toddlers who only receive verbal praise or receive no reward at all. This research suggests that even the youngest children are intrinsically motivated to be kind, and that extrinsic rewards can undermine this tendency. – Carter (2010)

While I have not yet looked to see if there is any direct research on this topic with regards to adolescence, this is part of the Montessori philosophy. Lillard (2007; Ch. 5) has an entire chapter on Extrinsic Rewards and Motivation that gets to the same point. She cites the research that gets to the specific point that extrinsic rewards, rewards that come from the outside such as praise, tend to demotivate once the rewards are removed.

Engaging in a well-liked activity with the expectations of a reward led to reduced creativity during that activity and to decreased voluntary participation in that activity later. (Lepper et. al., 1973) in Lillard (2007; Ch. 5)

Rewards have negative effects when they are clearly stated, expected, and tangible; read this book and you’ll get $5; or do this work and you will get better grades. However, rewards can work if you’re dealing with subjects that students find uninteresting and there is a very clearly specified set of steps that they can learn by rote.

“[R]ewards are often effective at the moment of their offering, so if there are no long-term goals, rewards help without causing harm down the road.” Lillard (2007; p. 157)

Rewards can help with basic learning, like memorizing facts, but intrinsic motivation is essential for tasks that require higher-level more creative thinking.

I try to praise or give tangible rewards very rarely, though it is often hard. Students look for praise sometimes (and sometimes for the oddest things), so when I do complement I try to use what Carter calls growth-mindset praise and say something like, “See, practice really pays off.” Praise the effort, not some intrinsic value the students have.

Kindness, and the science for raising happy kids

There has recently been quite a bit of scientific research on the evolutionary benefits of kindness. This article (found via onegoodmove.org) summarizes some of the work quite nicely. Again the theme is reciprocity; when we are kind to others, others tend to do more for us:

“The findings suggest that anyone who acts only in his or her narrow self-interest will be shunned, disrespected, even hated,” Willer said. “But those who behave generously with others are held in high esteem by their peers and thus rise in status.” – Anwar (2010)

Science for raising happy kids blog.

The article links to UC Berkley’s Greater Good Science Center and in particular, their Science for Raising Happy Kids website. Despite the somewhat Orewellian name (thanks Simon Pegg), the website has a lot of good information and a very good blog. I particularly liked a recent post by Christine Carter on Five Ways to Raise Kind Children. What she proposes aligns very much the Montessori philosophy.

PBS’s Inside the Teenage Brain is online (for free)

The full FRONTLINE documentary, Inside the Teenage Brain can be found online at PBS’s website. PBS has an entire website dedicated to the documentary which includes transcripts of interviews with neuro and cognitive scientists.

This is an excellent program (and website) that really delves into a lot that is counter-intuitive about adolescents. It is strongly recommended for both teachers and students, because it goes into the fundamental question of why your teens seem like aliens. Indeed, it describes the type of research upon which the Montessori Middle School program is based.

Rising bread

Yesterday, one of our experimental loaves of bread failed to rise, so re-tried it today and had a discussion about all the things we can do encourage it to rise. Since yeast is an organism, and we talked about the role of yeast in baking bread yesterday, this was a chance for the students to take what they’d learned and extrapolate into a new situation.

These types of situations pop up all the time in the student run business, especially when we try something new. It gets to the critical thinking skills adolescents need to practice. It is the reason Maria Montessori advocated for a boarding house middle school that ran a business. It is one of the reasons I insist that we start at least one new business every year in addition to our core pizza business.
