While listening to NPR the other day, my ears perked up to a story from On the Media called “The Pleasure Principle.” In it, Ethan Zuckerman (blogger and internet theorist) described a condition called homophily, and its potential danger while using the internet.

In short, homophily describes how we tend to flock together, seeking out ‘birds of a feather’. Perhaps Aaron Retica (NY Times) describes it best as “…our inexorable tendency to link up with one another in ways that confirm rather than test our core beliefs”.

Online, this tendency can be amplified. Ironically, with a wealth of diverse voices available to challenge our own ideas, we tend to use the internet to reinforce what we already believe – like an electronic pat on the back.

Thus, Zuckerman warns that homophily threatens to make us stupid. If we only seek out things with which we agree, then are we really using the internet as a tool to expand our own humanity?

This has obvious implications for anyone who has built up a social network like Twitter. I’ll be the first to admit that most of the tweets I harvest are from professionals involved in science or education (or both). And I can also see how easily homophily can infect my RSS reader too, as I direct it to intentionally pull out only RSS feeds that I want to read.

As I get the majority of my news from Google Reader, I have to wonder if my feeds are too homogenized and narrow-minded. I also have to wonder if my Twitter friends allow me to accept my own perspectives on life without confrontation or question. Are these tools just amplifying my own stupidity?

Of course, I am painting a fairly grim picture. Of course there are many benefits in developing social networks with kindred spirits; if anything, the internet is quite a useful tool in fostering this type of kinship. The danger lies in blocking out things that we need to see – diverse ideas, differing opinions and news from around the world.

Zuckerman suggests visiting sites like Digg, Reddit and StumbledUpon – sites that collect interesting stories and allow us to discover the world in its serendipity. I’d also suggest broadening your news feeds to include international news originating from different countries. Broaden your social network to include people from different professions and cultures. Allow yourself to be challenged by different opinions when people comment on your posts.

Why might we be concerned about homophily as educators? Think about it this way – you may seek out online diversity to become a better person, and in doing so, become a better teacher that is open minded, compassionate and has an abundant collection of fresh ideas. While you may not actually unearth a ready-to-go lesson plan, you may actually be able to share something about life that cannot be assessed on a standardized test.

In our recent interview with Bill Nye, he reminded us that the hardest thing for everyone to understand about the environment is that every single thing you do affects everybody in the whole world.”

Inspired by his words, I decided to replace some lightbulbs in my house with CFLs (compact flourescent lightbulbs). While I have been slowly replacing lightbulbs with CFLs as they burn out, I finally replaced a good number before they were burned out. It also helps that many companies are offering CFLs in different sizes and more attactive casings (i.e. flood lamps, decorative bulbs, etc). Thus, more than 90% of the lightbulbs in my house are now energy efficient.

Many stores will make this conversion easy for you with multi-packs and rebates as well. Energy Star even has a “choose a light” guide for you to help you decide which CFL suits your needs best. Nye suggests finding CFLs of the color you like, but with all things, the higher quality ones are usually more expensive.

So you go to the store and you buy one [compact fluorescent light bulb]. Ok, but if you replace every lamp in your house, or every lamp in the main rooms… Replace every one of those lamps, and you will see your power bill go down… Now there are some whining, unbelievable-freakin’ whiners out there who tell you that we can’t change to compact fluorescents because of the mercury – “there’s no way to get rid of the mercury that’s in those lights and it’s gonna kill everybody.” So let’s keep in mind that it was the year 1951 when American industry went to buying more fluorescent lamps than incandescent lamps. That is to say, if you work at any sort of factory anywhere, they have fluorescent lights – ‘cuz it’s so much cheaper. And so those lights are required by law to be recycled and the mercury recovered. And there are services that recover the lights and recover the mercury. So we just gotta do the same thing for domestic consumers – for people that buy ‘em for their houses. For cryin’ out loud – this is not, if I may, rocket surgery. This is actually a little more complicated that: trying to motivate everyone to do the right thing with regard to their old lamps. And of course it can be done; it’s a metal. Who doesn’t want to recover a metal? It’s valuable, it’s shiny, you can see it – of course you can do it. Download the Podcast

With shrinking school budgets, educators might consider looking to grants for project funds. Here are some tips (from the links below and from personal experience) for you if you are thinking of applying for a grant.

Preparation

  • Make sure your idea fits the grant criteria (location, non-equipment, etc)
  • Look for full grants and mini-grants too
  • May need to become member of professional organization(s) to be considered
  • Grants have two broad categories:
    • New proposals
    • Help to buildup existing projects
  • “Less is more” in proposal
  • Find colleagues as collaborators, community support
  • Look at successful proposals of other grant ideas
  • Find multiple uses of money, if possible
  • Involve students
  • Is your project sustainable beyond funding?
  • Gather ‘writing tools’
  • Success breeds success in grants

Writing

  • Use technical writing, not a creative writing style
  • Be clear and concise in writing style
  • Make sure to plan ahead and make the deadline, if not before
  • Display confidence & enthusiasm
  • Do your homework: research, cite studies that support your project
  • “Jargonize” appropriately
  • “Less is More” in writing
  • Develop specific, attainable goals in your project
  • Provide and timeline and a means for evaluation
  • Be prepared to showcase your successes already related to grant
  • Discuss potential problems and pitfalls
  • Consider your funding needs
  • Proofread! Avoid simple typos, misspellings, or awkward formatting
  • Critique your own proposal
  • Have others read your final draft as well
  • Turn in ON TIME (or ahead of time)

Follow-up

  • Some grants will contact you regardless of acceptance
  • Don’t get discouraged – a good idea is still worth doing. Look for other funding, try again next year
  • You may have a perfect idea/application and still get rejected
  • If rejected, ask grantor for comments/suggestions
  • If accepted, make sure to follow criteria for follow-up: report, publicity, etc

My district has recently installed Microsoft Sharepoint.  This is a dynamic tool (albeit from the MotherShip) that allows me to create and control groups where users can collaborate though shared documents, discussions boards, blogs, and wikis (and many other features).

My initial observations of Sharepoint made me realize that it has a distinct Microsoft footprint – heavy on tools, but clunky to use.  It reminds me of that spoof video fantasizing if Microsoft had packaged the iPod.  In any case, I futzed around with it for a while until I was semi-satisfied.

I have to admit – the discussion board is a powerful tool.  It engages my students on a level that they would not comfortable with in the classroom.  It challenges them to raise questions they would not ask in class.  It actually brings more discussion into the classroom.  And this was only after a week of discussion.  (NOTE: the power of a discussion board is not new to me, but this is the first time I am able to use one under my district’s IT reign).

This is exactly a tool I have been looking for, as I have a colleague in Sweden who wants to have our classes collaborate on a project.  Since SKYPE is blocked, this would allow the students to actually have that collaboration – supervised by me and my Swedish colleague.

Sharepoint is quite powerful in that it allows multiple configurations for its users with many layers of permission.  There are a few no-brainers that I already have setup to protect my students.  First – they can only post, but can’t edit or delete their entries.  This helps to reinforce the idea that once something is posted on the internet, it is always there.  Secondly, I don’t allow anonymous outside registration either – outside registration would have to be added by me or would have to be requested.

But I am not clear how to setup other student permissions/identities and if I should allow outside access for viewing.  I have a few options:

  1. Lock down the site so that ONLY students in my class can see and participate in the discussions
  2. Lock down the site as above, but allow it to be viewed by any student or teacher in the district
  3. Allow outside viewing, but protect student identities – make them create unidentifiable usernames
  4. Other options?

If you use student discussion boards, what advice do you have?  What are the benefits and drawbacks of these configurations?  I want students to be safe, feel free to speak their mind, but I also want to emulate the outside world as well.

You can see what I’ve done (and what the students have done) so far.  Their identities are protected – so I am currently using option #3.  Most likely, these settings will change in the future. [Link]

This school year, I was fortunate enough to have an interactive whiteboard (from Interwrite) installed in my classroom. I was hesitant to get it at first, as I would lose some valuable front-board real estate to have it mounted.

However, once I started using it, I soon found out some interactive and intriguing ways ways to enhance my instruction. Here’s what I like about it:

    1. More Student Interaction. I often find myself working too hard. That is, teaching to my students instead of working with them so that they can teach themselves. The IW has really helped to get students out of their seats and truly be more interactive in the lessons. Students love to write on the board, and it’s a great way to get students to contribute to the class.
    2. New Technology WOW Factor. There are only a handful of IW’s in the school right now, and students still think it’s a pretty cool gadget. It’s like I have the iPhone of education hanging on my wall (sorry for the metaphor).
    3. Great for Graphing. As a science teacher, I always have my students collect and graph data to analyze in class. The IW allows me to display graphs and write on them for analysis. The ‘write-on-able’ feature and the fact I can go back or save make the IW far superior to an overhead and some markers.
    4. Import Work and other Media. The IW allows me to easily import many types of media. This is particularly nice when working with online or CD-ROM textbooks, as I can incorporate media directly from student texts into my lessons. I can also use non-digital media, as we have a copy machine in our building that will scan documents and e-mail them to teachers.
    5. Save and Export Work. As I mentioned, I was a little cautious about losing some traditional whiteboard space. But I found that the IW actually expands this space, and I can create multiple pages and scroll back and forth. I can also record my movements on the IW to export them as a movie, and export the pages to a PDF file.
    6. Demonstration and Interactive Use of Programs. I particularly like to use RasMol for molecular imaging. I can use the same basic mouse functions on the IW to manipulate the molecule on the board, as well as certain structures with the IW pen. Here’s an exported video of me manipulating a GFP molecule with the IW.
    7. Interwrite Board + SMART Airliner Tablet = Extreme Whiteboarding! I still use traditional whiteboards integrated with the IW. I can assign multiple tasks for student groups to tackle on their own whiteboard, then take a picture of each and upload them to view. The students can present it on the board as I bring up their whiteboard picture. All the while, I am sitting in the back and can correct or add comments with a SMART Airliner Tablet or wireless keyboard/mouse. Again, the students produce, review and critique their entire lesson with my guidance.

Saturday, February 9th @ 7:00 PM
Lawrence University; Appleton, WI
Science Hall, Room 102

Please join us for this special Darwin Day event on Saturday, February 9th at Lawrence University. This event is designed to celebrate Darwin’s birthday and contributions to science. All students, educators and scientists are welcome. Food and door prizes will be provided.

Event Schedule
7:00 PM Keynote Presentations & Discussions (below)
8:30 PM Movie: Flock of Dodos
10:00 PM Social at the Viking Room on campus

Genetics and Speciation
Beth De Stasio, Raymond J. Herzog Professor of Science
& Associate Professor of Biology, Lawrence University
Using one or two recent examples, we will explore the connection between genetic change, phenotypic change, and speciation. Advances in our ability to dissect the genetic component of complex traits such as an organism’s morphology and color have allowed scientists to understand the changes that have led to reproductive isolation and subsequent speciation within particular populations. We will discuss the importance of reproductive isolation to speciation and mechanisms by which organisms can be isolated even when living in the same environment. Two examples will be explored.

Evo-devo and its contributions to Darwin’s legacy
Brigid O’Donnell, Postdoctoral Fellow of Biology, Lawrence University
Evolutionary developmental biology (or “evo-devo”) is a relatively new field of biological inquiry that elegantly illustrates both common ancestry and descent with modification in organic beings as envisioned by Charles Darwin. Evo-devo has provided us with a powerful perspective to explore the proximate mechanisms underlying the genesis of form as well as the evolutionary “tinkering” of developmental pathways across multiple scales of biological organization (from genes to entire structures!). I will highlight two specific case studies that have supplied exciting insights into the origin and evolution of the phenotype: the origin of body plans and the developmental basis of eyespot patterns in butterfly wings.

Coevolution of hosts and their parasites
Judith Humphries, Assistant Professor of Biology, Lawrence University
The coevolution of parasites and their hosts is often described as an “Arms Race”, where for example, the parasite evolves to increase the probability of infecting its host but in response, the host coevolves to better defend itself against the parasite. This is consistent with the “Red Queen Hypothesis” where both host and parasite must continually evolve in order to maintain fitness relative to each other. The relationship between parasitic brood birds such as cuckoos, and their hosts is often used to exemplify this hypothesis.

The Library of Congress has recently made a huge step in embracing such Web 2.0 concepts such as creativity, collaboration and sharing between users.

In an effort to provide better access to their collections, while symbiotically harvesting more information about those collections, the Library of Congress has created a Flickr page to host copyright-free pictures:

Out of some 14 million prints, photographs and other visual materials at the Library of Congress, more than 3,000 photos from two of our most popular collections are being made available on our new Flickr page, to include only images for which no copyright restrictions are known to exist…

…We want people to tag, comment and make notes on the images, just like any other Flickr photo, which will benefit not only the community but also the collections themselves.

More information is available on the Library’s Web site here and on the FAQ page here. You can read Flickr’s take here.

-from the Library of Congress Blog

While this is a tremendous offer, don’t forget about the slew of resources already available from the Library of Congress (including a section for teachers). Check them out for your classes and for yourself.

And there is also an underlying motive here. To help the Library on this project, Flickr has even created a new publication model for public collections called The Commons. Both the LOC and Flickr are hoping to encourage other public institutions to follow their lead. (In fact, the National Library of Australia is already doing a similar project with Picture Australia).

But of course, making these collections easily available has tremendous implications in education. This is a perfect way to teach about tagging and sharing in the classroom, while using historically important content without the worry of students accessing inappropriate content. And these pictures have no copyright restrictions, so they can easily be used by students and teachers in endless and creative ways in many classes. Too bad Flickr is blocked by Websense in my district.

What could you do with these pictures?

In the recent issue of Edutopia (Nov/Dec 2007, Vol. 3, # 8), Mitch Martin describes about how a good teacher must be bad at something to be good at teaching (Mr. Martin’s Oopses, page 10). I must admit – I’ve been thinking about this article a lot lately in both teaching and beyond.

Martin describes his attempts at learning how to play guitar, in how he had juggle practicing with his family and job – all the while feeling the exact frustrations and distractions that his students experience in his classroom.

After reading that passage, I instantly remembered back to my student teaching seminar, when the professor asked us “how can you relate to students who don’t care about getting good grades?” Coming from a small liberal arts college in the Midwest, most of us in the room were highly concerned with our grades. Getting grades was easy – empathizing with our students was hard.

After many years, I think that Martin offers at least a possible solution – put yourself in your students’ shoes. Translation: try something new where you might have to struggle a bit to succeed. Martin believes that “the best teachers are the ones who have struggled and succeeded.” I am reminded of a wise colleague of mine (now retired) who always told me that any good idea always starts with a LOT of fumbling and error.

So I challenge you all to make this your New Year’s resolution. Try something new – something in which you may have to struggle a bit in order to succeed. Not only will it enrich your life, but you’ll be able to better empathize with your students and it will make you a better teacher.

The use of digital photo frames to show slideshows is nothing new. But while I was setting up our house for Christmas (tree, lights, etc), I noticed the digital photo frame in the family room that has been repeating the same family pictures for the last 11 months (it was a 2006 Christmas gift).

Immediately, I realized that it could easily be used for another Christmas decoration. So I went to Flickr, searched for “Christmas” and found a slew of high quality, general Christmas pictures. After realizing that my frame only recognizes JPEG’s, I selected only those files – and ones that were shot horizontally (they look better in the frame than vertical ones).

So I was able to create a temporary, yet dynamic Christmas slide show (interspersed with family pictures at Christmas). Beyond using this idea for other holidays and special days, I realized that I could do the same thing in my classroom.

Imagine topic-specific pictures that can showcased to peak curiosity, engage discussion, and generally highlight the topic at hand. These pictures can easily be changed by swapping out memory cards, so it would be fairly easy to get it ready for several lessons over a school year.

As digital photo frames are getting pretty cheap, they can easily be purchased for the classroom. Or, if you are like me, then your old electronics end up in your classroom. I might have to upgrade mine at home and use my old one at school!

Inspired by Dale Basler’s stop-motion video project in physics, I recently had my freshman biophys students make videos that examine the factors affecting the rate of a chemical reaction.

We used a lab from an Addison-Wesley Chemistry lab manual entitled “Factors Affecting Reaction Rates”. This lab was ideal, as the instructions are already neatly divided into 4 parts, whereby each part examines what can affect the rate of a chemical reaction (temperature, concentration, surface area and use of catalyst). Students were divided into 8 groups of 3 (2 groups for each concept).

These were the guidelines for the videos:

  • 1-2 minutes in length
  • Describe setup & document experiment
  • Discuss results (with graph or data table)
  • Show balanced reaction
  • Discuss concept

This was a 5-day project (2 days in lab, 1 for taping, and 2 for editing in the computer lab). I gave the students just the basics in order to use Windows MovieMaker, and helped them on-the-fly with questions.

Besides the final project, perhaps the best part of the project was viewing them all in class. Not only were we able to discuss the concept in each video, but students also critiqued each video in content and in quality. This evolved into a really productive discussion on how important it is to be able to communicate science effectively.

This turned out to be a great project that the students really enjoyed. The only negative comment I heard was “the reactions were kinda boring” (all kids want fire and flames). Now that I know the students can handle this type of work, my mind is spinning on what movies they can make in the future using other science tools – graphical analysis, digital microscopy and RasMol (molecular visualization software) come to mind immediately.

Here is an example video:
