I’ve been meaning to share this project idea with Josh Burker, author of The Invent to Learn: Guide to Fun and the Invent to Learn: Guide to More Fun books, for more than a year.

While on one of the fabulous London Walks tours (I’ve done dozens of them) of Chelsea in London last year, I learned that before houses had street numbers assigned to them, people shared cards with a rendering of their home’s fanlight depicted on it. This practice dates back to 1720.

The function of the fanlight is to light a home’s entry way, but many of London’s upscale townhouses feature a semicircle shaped fanlight in which a geometric pattern exists. Each pattern needs to be different, at least in a particular neighborhood, in order to depict the occupants of the home for deliveries and visitors. Below are some of the photos of fanlights I took while walking around Chelsea.

Here’s the project idea…

  • Use your favorite dialect of Logo (Turtle Art, SNAP!, Scratch, etc…) to design a unique fan light. Teachers may support the activity by providing the code for drawing a uniform semicircle in which each student’s fanlight pattern must fit.

Extension

This is a good project for employing the concept of state transparency; in programming as in life, it is a good idea to return to where you started. Returning the turtle to its initial starting position and orientation allows you to repeat the pattern elsewhere on the screen and perform various transformations on it.

Try these challenges

  • Use Logo/MicroWorlds/SNAP!/Scratch to program the turtle to draw a row of townhomes with different fan lights in each window.
  • Change the scale of your entire neighborhood.
  • Change the scale of your fanlight window without altering its shape.
  • Allow the user to specify the scale of the fanlight and draw it to that scale.
  • Create a more abstract illustration using your fanlight in different ways.

That’s it!

Happy programming

Two-Day Seminars with Will Richardson in October 2019 in DC, NJ, & Boston – Register today!

I originally wrote a version of this article in 2007, but the topic is even more timely during today’s period of introspection regarding violence, civility, gun control, widening wealth disparities and education reform. Our daily discourse is filled with reckless nostalgia for the good ol’ days of the White Citizens Councils and the preposterous claims that Dr. King would love charter schools, the destruction of unions, the demonization of public school teachers and having poor children do the work of school janitors.

It is unconscionable to reduce Dr. King’s life, work and sacrifice to the few paltry sentences fed to us by the textbook industry or Republican politicians cherry-picking happy talk rather than confront the societal demons King identified and that are still with us.

This epidemic of ignorance can only be cured by educators! (also read: The Help: A Teacher’s Guide for more resources)


This Monday is Dr. Martin Luther King’s Birthday and February is African American History Month. Both occasions were created as a way of honoring the sacrifice of Dr. King and the contributions of millions of African Americans before him. It is a somber occasion in which to confront the hideous crimes of institutionalized racism and to celebrate the achievements of people who overcame insurmountable odds to enjoy the unfulfilled promises of the United States Constitution.Schools are the natural setting to inform students of our history, warts and all. Yet we tell so few historical stories and most of those narratives are watered down until they become fairy tales and meaningless happy talk. Face it, ______ (Black, Women’s, Latino…) History Months are necessary because the information presented to students is so biased, simplistic, incomplete and often times just plain wrong.

Please take a moment to answer the following questions. Think of it as a quiz if you wish.

  1. What do you know about Dr. Martin Luther King Jr?
  2. What do your school social studies texts say about his life and work?
  3. How much class time is dedicated to the life and times of Dr. King?
  4. Have you done any independent reading or research into the life of Dr. King?
  5. Why did Dr. King speak in Washington that day in August 1963?
  6. What was the event called?*
  7. Was Dr. King the only speaker?
  8. Why wasn’t’ President Kennedy at the speech? Wasn’t he Dr. King’s friend?
  9. Who was A. Phillip Randolph?
  10. Who is John Lewis?
  11. Who was Bayard Rustin?
  12. Where was Malcolm X that day in 1963?
  13. Why was Dr. King in Memphis before he was assassinated?
  14. Bonus question: Are there serving members of Congress who voted against the federal law establishing the King holiday?

Many teachers use the King holiday as an opportunity to tell students “all about” Dr. King. “He had a dream…” They use resources like these fabulous materials recommended for teachers on the web.

  2. http://www.windmillworks.com/games/dream.htm

Note: I highly recommend you click the links to see the garbage used to honor one of the greatest men who ever lived.You can’t teach about Dr. King without the “I Have a Dream Speech,” right? Textbooks and various multimedia products have sliced, diced and filleted a 30-second perky excerpt from Dr. King’s speech.

Since students will be unlikely to be introduced to any of Dr. King’s other rhetorical output, might I suggest that you play the entire speech for your students. Of course you should listen to it yourself beforehand. The entire speech runs approximately 17 minutes. If the Internet has educational value, it begins with the access to primary sources.

You may find a COMPLETE video clip of the ENTIRE “Dream” speech, alongside the unabridged transcription of the speech at the following sites:

So, what do you think? Do the content, intent and emotion of the whole speech paint a different picture than the one portrayed by the one-paragraph textbook version recited by politicians?In an age when educators profess profound concern about information literacy why not discuss why the entire message of the speech has been hidden by curricular omission. That and the substance of Dr. King’s actual speech should generate a few year’s worth of curriculum alone.

Schools are the natural setting to inform students of our history, warts and all. Yet we tell so few historical stories and most of those narratives are watered down until they become fairy tales and meaningless happy talk.

Even Google got in the business of infantilizing the life of Dr. King with today’s logo.

On this Martin Luther King Birthday National Holiday, I give thanks to the World Wide Web and YouTube for ensuring that future generations of children will be free to learn history aside from the standardized content being currently delivered to them.


Supplemental Resources:Educators serious about sharing the heroic ongoing American struggle for civil rights should read Herbert Kohl’s brilliant book, “She Would Not Be Moved: How We Tell the Story of Rosa Parks and the Montgomery Bus Boycott.” The first half of the book demonstrates how the Rosa Parks story has been turned into a fantasy taught to children and offers the facts children are denied. The second half of the book discusses how teachers can fairly teach complex or controversial issues to children of all ages. I also recommend, Teaching What Really Happened: How to Avoid the Tyranny of Textbooks and Get Students Excited About Doing History by James Loewen.


*The March on Washington for Jobs and Freedom took place in Washington, D.C., on August 28, 1963.

Why do you suppose “jobs” gets left out of the classroom discussion?

Watch the following clip and see how Dr. King might have responded to the magical thinking on race being advanced by U.S. Secretary of Education Arne Duncan or Governor Walker or Governor Kasich or Governor Daniels or Governor Christie.

If you were ever curious about what I believe or do as an educator, my summer institute, Constructing Modern Knowledge, represents me quite well. The energy, creativity, projects developed and guest speakers at last month’s institute makes CMK 2011 one of the proudest accomplishments of my career. Even when we lost electricity for a couple of hours, project-based learning continued unimpeded!

Educators from across the USA, Costa Rica and Australia came together for four days of project-based learning, collaboration and conversation with some of the greatest thinkers of our age. Registration will open in early September for the 5th Annual Constructing Modern Knowledge institute, July 9-12, 2012 in Manchester, NH. Add your email address to the mailing list for discount registration information as soon as it becomes available.

I’ve done a bit of work documenting a few of the learning stories captured at CMK 2011. I hope you and your colleagues enjoy them!

  • Lessons learned from a creative, collaborative, computationally-rich, non-coercive, constructionist learning environment.
  • Impossible – Documentation of a project blurring the boundaries between science, technology, engineering, mathematics and an insane project idea successfully realized.
  • Serendipitous Learning – Documentation of a project blending S.T.E.M., invention, tinkering, history and linguistics inspired by an unlikely “object to think with.”
  • Constructing Modern Mathematics or is it History? English? – Documentation of a project in which mathematics, computer science, history and art come together in a computationally rich environment.
  • Tinkering Resources – Lots of links, resources and inspiration.
  • CMK 2011 Construction Materials – Interested in downloading a list of the open-ended creativity software and construction materials being used at Constructing Modern Knowledge 2011?
  • A Constructionism Primer
  • Three articles about effective project-based learning
  • What attendees said about Constructing Modern Knowledge 2010 (including Chris Lehmann)
