Shared Assumptions & Changing Culture

The only thing of real importance that leaders do is to create and manage culture. If you do not manage culture, it manages you, and you may not even be aware of the extent to which this is happening.

Edgar Schein

I’m reading An Uncommon Theory of School Change for a class, and the image text struck me. Actually, it knocked me to the floor.

Specifically, the idea of “shared assumptions” among a school’s teachers and staff. Every organization has these shared assumptions, and they all influence how the day-to-day functions of the organization, specifically in defining the organization’s culture, as Ed Schein explained.

So, why are these shared assumptions important in our schools?

Easy: they play a large part in how students learn. If teachers have decided, perhaps with the best of intentions, that “our kids can’t do that“–whatever that is–then it’s highly likely that the kids won’t do that.

(Somehow, this has turned into a bad commentary on one of Meat Loaf’s greatest hits…)

This line of thinking also shows up in John Hattie’s work, as teacher estimates of achievement significantly impact student learning.

Part of our work to change schools should involve a hard look at our shared assumptions and, perhaps, some adjustments to those assumptions.

After all, you know what happens when you assume something…

Rethinking the Public Commonplace Book

A bit of commonplace memories from Austin, TX

The great Cory Doctorow celebrated four years of his Pluralistic blog last week. As such, I felt it a good time to rethink my own attempts at creating a public commonplace book.

I’m unsure how effective my work at creating a commonplace book has been over the past couple of years, but I’m getting there.

I first spoke about this idea here, inspired by Cory’s work, Austin Kleon’s, Ryan Holiday’s, and a host of others.

My biggest fault is that I don’t post enough stuff. Why?

Because I’m always worried that what I post isn’t “good enough” or planned enough, or whatever. It’s silly, I know, but as a lifelong perfectionist and anxiety sufferer, it’s difficult not to think about those things.

So, I shall make another attempt to share all the awesome things I find, regardless of whether or not they specifically fit into some mold that I feel I must inhabit.

I don’t fit well in any mold. I have too many interests and passions. One day I might talk about rethinking education and the next I’ll talk about picking up a cool comic at my local shop.

Who knows where this journey will go? Not I, said the frog.
