The Science of Not Knowing

NOTE: This is a cross post from my mostly about reading blog In One Place. But the ideas about science are important for educators as well.

There are moments when reading and real life come together. Not to be too dramatic: but now is one of those times. As oil spews into the Gulf of Mexico, my companions for the journey are Annie Dillard and Wendell Berry. And, both of them make the same essential point about science: the real power and terror of science is that neither doesn’t nor can know everything.

For Dillard, the not-knowing can be seen in the natural world, in something as seemingly simple as an elm leaf:

Or again, there are, as I have said, six million leaves on a big elm. All right…but they are toothed, and the teeth themselves are toothed. How many notches and barbs is that to the world. In and out go the intricate leaf edges, and “don’t nobody know why.” All the theories botanists have devised to explain the functions of various leaf shapes tumble under an avalanche of inconsistencies. They simply don’t know, can’t imagine.

Berry’s comments are in response to Edward O. Wilson, who in his book Consilience, celebrates science and discounts the possibilities of learning in and from mystery:

He understands mystery as attributable entirely to human ignorance, and thereby appropriates it for the future of human science; in his formula, the unknown = the-to-be-known…If modern science is a religion, then one of its presiding deities must be Sherlock Holmes. To the modern scientist as to the great detective, every mystery is a problem, and every problem can be solved. A mystery can exist only because of human ignorance, and human ignorance is always redeemable. the appropriate response is not deference or respect, let alone reverence, but pursuit of “the answer”.

Don’t nobody know why…and yet we teach students that there are answers. I am outraged that BP was not required to have a solution to what was clearly a potential problem. I suppose we can blame it on a failure of the imagination but the cynic in me can’t help but blame it on a desire for profit. And an unwavering belief in science to solve any problem. I, of course, am hoping along with everyone else that this IS a problem science can solve, and quickly, but at what cost?

BP, with its string of abuses, clearly has not real concern for the world community other than as a market for its oil. Berry points out that science is often conducted with economics rather than community in mind and quotes Wilson’s description of the “cardinal principle in the conduct of scientific research: Find a paradigm for which you can raise money and attack with every method of anaylsis at your disposal.” Berry goes on:

This principle, in effect, makes the patron the prescriber of the work to be done. It would seem to eliminate the scientist as a person or community member who would judge whether or not the work ought to be done. It removes the scientist from the human and ecological circumstances in which the work will have its effect and which should provide one of the standards by which the work is to be judged; the scientist is thus isolated, by this principle of following patronage, in a career with a budget.

Hmmm…as I typed those last words, I realized how hard I was being on scientists, even if I was only channeling Berry. I’m blaming scientists for the flaws in a system that is much larger than them just as teachers often get blamed for failed reforms for which they had no responsibility. I imagine some scientist, in a planning meeting for the platform, quietly suggesting that this could be a problem. His solution, however, did not meet the cost analysis: what was the chance of this happening and how much would it cost? What the number crunchers failed to consider, however, was the cost if it DID happen! This could ruin BP. I don’t think anyone has the heart to bail them out.

The Almost Paperless Classroom

Earlier this semester, I did an interview with WM’s Director of Academic Information Services about my “paperless” classroom. I explained how I was avoiding doing any printing or copying but offering documents online and reframing activities to take advantage of the web.

A quick example: I play the TPACK game with my students, putting together content, technology, and pedagogy to create ideas for using technology in instruction. Normally, it is a very paper heavy activity as I print out cards and lesson sheets. This semester, as I prepared for that class, I considered digital ways to present it. I ended up using an online flash card site to create the game. The flash cards had a pedagogy on one side and a content area on the other and then students were challenged to come up with their own ideas. I skipped the paper recording sheet, opting instead to have them use a wiki page. It was fortunate that I had done this…the night of the class I was sick so we met in Elluminate instead and having the online resources made it much easier to stick with the plan!

But, last night, the paperless dream came to an end. We were using Scratch and while I talked the students through an introduction, I wanted them to be able to explore on their own. But I also knew that some would appreciate some written handouts to follow along with and Scratch has these great program cards where you learn a bit of code at a time. I considered just having them access the cards online…but trying to navigate between the card and the Scratch window on the laptop is often difficult because there just isn’t enough real estate on the screen. So, I printed…ten copies of three pages which I handed out a bit ruefully.

There’s a lesson here, though, about practicing zero tolerance: it just doesn’t work. My students would have been frustrated if, in order to keep up with my paperless dream, I did not provide them with what they needed to be able to learn. In this case, it was a piece of paper. They agreed with me that they preferred to have a paper guide along side their laptop rather than having both items on the screen. So, it was a pedagogical decision and one that I stand by.

Next week, we meet in Second Life so we will be both paperless and classroomless so maybe that makes up for my 30 pieces of paper.

Teaching, teaching, teaching

I am teaching three courses this semester. Two are face to face and one is online. I’ve taught the undergraduate face to face course for more than five years. It’s the typical “tech” class that pre-service teachers have always had to take. When I took it some 22 years ago, I learned about using film projectors and got a brief introduction to computers through one class period devoted to logo. Even then, I was hooked, and my final project was created on my Tandy 1000 using a free database program to develop a gradebook.

Fast forward nearly a quarter of a century (how DID I get this old??), and the course covers everything from Inspiration to Google Earth to Quest Atlantis. In more recent semesters, I’ve designed the course around the concept of TPACK–Technological Pedagogical Content Knowledge–to help students see the relationship of technology to the other areas of their learning. I like the course and enjoy spending time with 20-somethings who are excited about becoming teachers. I haven’t met with this year’s group yet. Monday is our first class. The section I teach focuses on elementary education and this semester I have several men in the course, which is unusual.

The two other courses–both graduate and both focusing on educational technology–are new to me. One is online and one is face to face. I developed the syllabus for the latter. The former has already been developed and I am working as a facilitator. But, the real difference I’ve discovered is how quickly I can bond with the students. I met with my face to face class last night, and I already love it. I knew some of the participants prior to the class so we settled in pretty well. And for the few I didn’t know, I already feel like I have a sense of how we will work together.

Even though the online course started a day earlier, I still don’t have much of a sense of the students. A few of them have posted to the discussion forums, but none have posted their pictures yet nor completed the audio assignment. So, I have no idea what they look or sound like! I’ve got names and email addresses and that’s it. I’ve been checking in several times a day to see what’s happening and am disappointed when there are no new posts for me to review. It is going to be a slow process and I am eager for Monday morning to come so I’ll at least know what they look like, well that is if they actually post pictures of themselves. The course creator gave them the option of posting any picture and I thought about changing that but didn’t want to immediately go in and start rearranging. So, I’m hoping most of them choose to post their own pictures rather than Marge Simpson or a sports team logo. That tells me something about them, certainly, but doesn’t help me really visualize them.

It promises to be an interesting semester! My face to face grad course participants will be keeping blogs and I’ll be posting more here as well to keep up with them.

VSTE Webinar: Quest Atlantis

Mark Your Calendars: The VSTE Webinar for January will be held Thursday, January 28, at 7:30 PM. We’ll be taking advantage of Learn Central‘s free Elluminate access. Mary Ellen Davis and Linda Carpenter from Virginia Beach will be reprising their excellent VSTE presentation about this online virtual problem solving tool for students. Come join us for an inspiring, interactive meeting. Here’s the URL for the announcement: http://www.learncentral.org/node/46740. You can register to let us know how many to expect but you can also just stop by.

This webinar is sponsored by the Education and Programs Committee of the VSTE Board of Directors.

Cross Post: Check Out Our Voice Threads

I posted this in the VSTE Ning site where my undegraduates are sharing their learning this semester.  But, I thought it might be of interest to a wider audience.

This semester, I added Voice Thread to my course and I’m glad I did. They are all tied to the Standards of Learning, Virginia’s standards. Most of my students are planning to use them as part of their student teaching experience.

Here’s the list with the links:

Simple and Compound Machines: http://voicethread.com/share/207443/

Weather Instruments: http://voicethread.com/share/207433/

Who Eats What: http://voicethread.com/#q.b207433.i1089152<

Magnets: http://voicethread.com/share/213467/

By the way, here’s the one I created for them. It reviews the different tools we have studied and asks them to think about how they can be integrated into the classroom. Please feel free to add your comments:

I’ll end with a thank you to my Twitter buddies who had excellent ideas for how the students can easily allow their students to comment on their threads. I am reminded of the power of my professional learning network and I hope my students are coming to see its power as well.
