History For All

roman colliseum

How Earth Made Us is a documentary series produced by the BBC.  Like many BBC programs, the cinematography is spectacular.  But, perhaps more interesting, is the approach the program takes to history.  Instead of only examining human interactions, the program focuses on how natural forces such as geology, geography, and climate have shaped history.  And, the whole series is available on YouTube.

In the first episode, Water, host Iain Stewart explores the effects that extreme conditions have had on human development.  He visits the Sahara Desert, which receives less than a centimeter of rainfall each year, and Tonlé Sap, which swells to become the largest freshwater lake in southeast Asia during monsoon season.  The contrast is striking.  One interesting factoid is that the world’s reservoirs now hold 10,000 cubic kilometers of water (2400 cubic miles).  Because most of these reservoirs are in the northern hemisphere, they have actually affected the earth’s rotation very slightly.

The second episode, Deep Earth, begins in a stunning crystal cave in Mexico, in which crystals have grown to several meters long.  The cave, which is five kilometers below the earth’s surface, was discovered by accident when miners broke into it.  I can’t imagine what they thought when they first set foot inside.

The third episode, Wind, explores the tradewinds which spread trade and colonization, which lead to the beginning of globalization.  This brought fortune to some who exploited resources and tragedy to others who were enslaved.  The view from the doorway through which thousands of Africans passed on their way to the Americas is a chilling reminder of this period of history.

Fire, the fourth episode, moves from cultures that held the flame as sacred, to the role of carbon in everything from plants to diamonds to flames.  And carbon is also the basis of petroleum, which has powered the growth of humankind.  Several methods of extracting crude oil around the world are explored.

The final episode, Human Planet, turns the equation around tying the first four episodes together by looking at how humans have had an impact on the earth. One of the most compelling examples is the Great Pacific Garbage Patch which is the result of ocean currents bringing plastic and other debris from countries around the Pacific rim.  This garbage collects, is broken down by the sun, and eventually settles to the bottom to become part of the earth’s crust.  This is juxtaposed to rock strata in the Grand Canyon, pointing out that eventually, one layer of rock under the garbage patch in the Pacific will be made up of this debris.

In all, there is almost 5 hours of documentary video here.  It is a compelling production with spectacular imagery.  There are any number of ways to use these videos with an ESL class.  And because they are available on YouTube, there are even more options available to an ESL instructor.  Instead of everyone watching together in the classroom, the videos can be posted in an online content management system and students can watch them anywhere, anytime on their laptops and smartphones, if they have access to that kind of technology.  And if the videos are being watched outside of the classroom, there are more options for assigning different groups of students to watch different videos and then have conversations with students who watched different episodes.  The ubiquity of online video can bring learning to students outside of the classroom.

21st Century Newspapers

rolled up newspapers

A long, long time ago (maybe 6 or 7 years now) I taught an elective ESL class centered around a student newspaper.  We tried various formats including weekly, monthly, and quarterly editions, which ranged from 2 to 32 pages.  We also experimented with various online editions, but at the time that mostly consisted of cutting and pasting the documents into HTML pages.

Fast-forward to 2011 and look how online publishing has changed.  Blogs are ubiquitous, if not approaching passé.  Everyone but my Mom has a Facebook page.  (Don’t worry, my aunts fill her in).  And many people get news, sports scores, Twitter posts, friends’ Facebook updates, and other information of interest pushed directly to their smartphones.

It’s no surprise, then, that a website like paper.li has found its niche.  The slogan for paper.li is Create your newspaper.  Today.  Essentially, paper.li is an RSS aggregator in the form of a newspaper.  RSS aggregators are nothing new (see iGoogle, My Yahoo!, etc.).  As the name implies, the user selects a variety of different feeds from favorite blogs, people on Twitter, Facebook friends, etc. and aggregates the updates onto one page.

The twist with with paper.li is that the aggregated page looks very much like a newspaper — at least a newspaper’s website.  For people not on Twitter, Facebook, and Tumblr, paper.li might feel much more comfortable.  Also, publicizing one’s pages seems to be built right in to paper.li’s sourcecode.  I say that because I first learned of paper.li when I read a tweet that said a new edition of that person’s paper was out featuring me.  How flattering!  Of course, I had to take a look.

Would paper.li be a good platform to relaunch a student newspaper?  It might.  If students have multiple blogs, paper.li could certainly aggregate the most recent posts into one convenient location.  Other feeds could also be easily incorporated as well.  (Think of this as akin to your local community newspaper printing stories from the Associated Press.)  The most recent news stories about your city or region, updates from your institution’s website, and photos posted to Flickr tagged with your city or school name could each be a column in your paper.li paper right beside the articles crafted by the students themselves.  You could even include updates from other paper.li papers.

To see examples of paper.li papers, visit the paper.li website.  (And note that .li is the website suffix — no need to type .com no matter how automatically your fingers try to do so.)  You can search paper.li for existing papers to see what is possible.  A search for ESL, for example, brought up 5 pages of examples, some with hundreds of followers.  Take a look.  You might just get an idea for your own paper.li.

Teaching with Google Images

canoes on google image search

In a recent meeting with the executive council of our student association, one of our class representatives suggested organizing a canoe trip.  Judging by the puzzled looks around the boardroom table, many students did not recognize this word.  So, I pulled up Google Images and did a search for canoe.  The results were similar to what you see above.  Instantly, students could understand the word and the discussion could continue.

I really enjoy the challenge of working with a group of students with a wide range of ability.  Using Google Image search is a good way to help level the playing field so that students can communicate with each other more efficiently.  If you have a projector and internet access in your classroom, images can be pulled up very quickly as a teaching aid.

A word of caution, though.  Be sure to set the Safe Search setting to “Use strict filtering” if you are doing a search in front of a whole class in order to reduce the chance of objectionable images appearing.  And be aware that even strict filtering is not 100% perfect.  So, if you are working with a group that is young or particularly sensitive to certain images, be ready to hit the back button immediately or, better yet, mute the image on the projector until the search comes up, preview the images, and then make the projection available to the class.

Once you begin using it, Google Image search is the kind of simple tool that you will wonder how you lived without.  While there are certainly benefits to having students define unknown terminology for each other, there are also times when you just want to provide a few words to define a term and move on.  In these cases, an image search is worth a thousand words.

Show Me The Money

statue of liberty dollar coin

I’ve posted about finding royalty- and copyright-free images on line before.  In this post, I’d like to share an often overlooked source: the U.S. Government.  Many government departments have images in the public domain, which usually means that teachers can use them in presentations, classroom activities, and almost any not-for-profit ways you can imagine.  Of course, there are exceptions, so be sure to read the fine print.

coinsThe U.S. Mint

The Mint publishes some very nice images of the money it produces including coins commemorating states, presidents, first ladies, national parks, and significant historical events.  Most are available for free download, though a few are copyrighted (such as the Sacagawea dollar coin).  There are also a few anti-counterfeiting restrictions on reproducing paper money, so be sure to read the fine print on the website.

The National Aeronautics and Space Administration has some amazing copyright-free images and videos available.  Whether you are looking for images of astronauts, rockets or other spacecraft, or images of outerspace, the NASA website has you covered.  Some of the images include those from the Hubble Telescope which has captured extraterrestrial images for over a decade.  There are lots of science- and engineering-related images, and the website makes it easy to search for them.

washing a dogCDC

You might not ordinarily think to look on the website for the Center for Disease Control and Prevention, but but the Public Health Image Library has lots of interesting stock images available, related to topics such as home safety, personal hygiene, agriculture, child safety and more.  Of course, you’ll also find lots of images of bacteria, microscopic pests, and other diseases, some of which may not be suitable for children.

More

For links to photos from more U.S. Government photos and images, visit the USA.gov website.  You will find links to images from lots of other departments related to agriculture, the environment, defense, safety, science and technology and others.  In essence, these images are “free” because you’ve paid for them with your taxes.  So, don’t hesitate to take a look and use them if you need to.

Kinect Development

microsoft kinect hardware

Microsoft recently announced plans to release a software development kit (SDK) for the Kinect.  This should allow academics and enthusiasts to find new ways to connect the motion-sensing Xbox hardware to other platforms, such as desktop and laptop computers, much more easily.  In short, there should be many more Kinect hacks to come.

I’m still not sure how this would directly apply to classroom teaching, although it stands to reason that these applications could someday replace physical interactive whiteboards in the same way that Kinect was originally designed to replace physical videogame controllers for the Xbox.

For more, see my previous post on Kinect Hacks and below for some new examples of how Kinect is being used in new and exciting ways.

Control Windows 7

The touchless multitouch is really nice.  Mice are so 2008.

3D Tetris with Face Tracking

As the user moves his head, the perspective on the screen changes to match so that the 3D perspective is constantly updated.

Kinect Lightsaber

A wooden stick becomes a lightsaber in real time.  This would save hours of  frame-by-frame editing.

Balloon Body

After Kinect scans your body, use your scroll wheel to expand or contract the surface.

Christmas Lights

Use Kinect attached to a bunch of dimmers to control Christmas lights for a very nice effect.

Flying Robot

The 3D capability of connect makes it perfect for a robot that navigates three-dimensional space.

Hey, You Guys!

light bulb

In the 1970s, The Electric Company was a kids television show made by the Children’s Television Workshop, the same folks that made Sesame Street,  but designed for a slightly older, getting-ready-to-read audience.  Fast-forward to 2009.  The Electric Company is being made again by what is now called Sesame Workshop.

Each half-hour show contains a main story featuring The Electric Company kids and their antagonist Prankster peers.  Vignettes interspersed between parts of the story focus on letters and sounds that relate to the vocabulary highlighted in each episode.  Most are catchy songs or games and contests played between the characters.  I’ve embedded several videos featuring silent e in this blog post.

The best thing about this show is that it does not baby it’s audience.  Scott Cameron, the Director of Education and Research for Sesame Workshop, has experience teaching ESL with music and games.  The focus of The Electric Company is on motivating children to read and this really can’t be done by talking down to an increasingly media-savvy audience.

In our house, Silent E is a Ninja (below) is a favorite that has achieved earworm status.  Try to watch it once or twice and tell me it’s not stuck in your head the rest of the day.  You’ve been warned.

The Electric Company has even brought back its classic silhouetted heads reading words together.  These are really effective demonstrations of learning to read by sounding out words.

Videos are available on the Electric Company YouTube Channel and on the Electric Company website (which includes a section for parents and educators).

Will these videos work with adult students?  It depends on the student.  These videos are fun and poppy and targeted to a younger audience.  But as a way to expose language learners to lots of fun, catchy, repeatable reinforcement, these really can’t be beat.  Do you know of other good videos?  Post a link in the Comments section.

2010 in review

automatic transmission

I got this auto-generated post direct from WordPress, which hosts ESL Technology.com, and thought some of it was worth sharing.  Every time I login to my blog, I can check on these numbers and other interesting data.  I can see how many page views I’ve had by day, week, and month as well as which pages were most popular and what sites are referring people to my blog.  More interesting than the numbers themselves are the fact that this data is so easily available that WordPress can automagically pull it together into a blog post for me.  (Incidentally, you can search “2010 in review” on WordPress to find other bloggers who have posted the autogenerated post.)

This kind of data is becoming easier and easier to work with — to mashup.  And all kinds of new software allows us to pull together lots of data in enlightening ways.  Governments that are making this kind of data available are finding citizens stepping forward to develop ways to make it more useful.  See Tim Berners-Lee’s TED Talk for a six-minute rundown of the highlights, below.

I recognize that the numbers generated for me by my blog are not as important as which roads are impassable after an earthquake in Haiti.  But, on almost every scale, this data is becoming easier to find, use, and mashup.  Some of our students may already be doing this.  Surely, many are not.  Developing the ability to work with this kind of data in very dynamic ways is sure to be an asset, if not an expectation, in the near future.

So, without further ado, my numbers.  Thanks for reading.
