Interactive Videos

mocap character

When I hear the phrase interactive videos, I think of people covered in florescent mocap pingpong balls or choppy, Choose Your Own Adventure-style stories like Dragon’s Lair.  And there are those.  But, it seems that some creative tinkerers have pushed the envelope with some of YouTube’s interactive features and come up with some interesting results.

How can they be used with ESL and EFL students?  Well, in addition to viewing and interacting with the videos and then discussing or reporting on the experience, students could be challenged to determine how the videos were made.  For the more ambitious, students could make their own videos using the same techniques.  Some of them, like the Oscars find the difference photo challenge would be relatively easy to remake.

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.

Poll Everywhere

clipboards

Ever stare out into a roomful of your students’ faces as you explain the role of the comma in differentiating restrictive and non-restrictive adjective clauses?  I have.  After a few terms, I began to wonder whether those blank stares indicated that students were overwhelmed by the topic, or bored because they already understood this material and couldn’t wait to move on, or were just plain bored (though I was pretty confident the latter was true.)

I thought it would be great if we teachers could adopt the same technology that the network news teams use when they take a roomful of average citizens and make them watch debates with a dial in their hand.  By turning the dial left when they are happy and right when they are not, an average response is displayed in a graph that scrolls across the bottom of the screen.  Wouldn’t it be great if students could dial between “I don’t understand. Slow down.” and “I get it.  Move on.”?  For now, we must make do with the analog, “Any questions?”

Getting live feedback can be very useful in the classroom.  Poll Everywhere is a website that makes creating live polls extremely easy.  With a free account, you can create a poll that allows up to 30 responses by web, text message, smartphone or Twitter.  You can even download your poll on a PowerPoint slide, which you can use to observe the results as they roll in.  More features are available for paid accounts.

Polls are very easy to set up, but there are lots of good online tutorials out there, including this one by Sue Frantz.  These kinds of polls can do a great job of gathering instant feedback from your students using technology they likely already have with them (instead of requiring them to purchase Clickers, devices with only one function.)  Whether asking students if they the pace of the class is appropriate or checking comprehension of content, Poll Everywhere is an extremely flexible tool that can be used in a wide variety of situations.

Kinect-Based IWB

infrared points of light projected from a Kinect

Ever since a $3000 bounty was placed on cracking open Microsoft’s fab new gaming hardware, the motion-sensing Kinect for Xbox, hackers and tinkerers have been putting the open-source drivers to lots of interesting uses on platforms that Microsoft never envisioned.  I’ve written about interesting Kinect hacks before (and before that,) and I’ve written about my experience with the Wii-based $50 Interactive Whiteboard (IWB,) but I haven’t seen a fully-developed Kinect-based Interactive Whiteboard.

Perhaps an Interactive Whiteboard is too narrow a description.  Many of the pieces are in place (see below) to interface with a computer using Kinect.  So, as with the Wii-based IWB, any application you can use on your computer can be controlled by this hardware.  If you connect your computer to a projector, you essentially have an Interactive Whiteboard.

Is the Kinect-based experience different from a Wii-based IWB or a Smartboard?  Almost certainly.  There would be no need to touch the screen at all, but rather to gesture in front of the Kinect to interact with the projection on the screen.  Would this be an improvement?  I’m not sure.  A touch-based IWB is more analogous to traditional whiteboard that uses markers and an eraser.  So, the touchless experience would be quite different.  I need to try it myself to really wrap my head around the opportunities that this motion-sensing interface offers.

I’m not sure if anyone here at Ohio State is working with Kinect as an interface for non-Xbox applications.  But I do know that the Digital Union has a Kinect which could probably be used to see if and how things work.  If anyone else is interested in trying to pull this together, drop me a line or leave a comment.

Web Browsing in 3D

3D glasses

Everything else is available in 3D (movies, televisions, the real world), so why not 3D browsing?  I recently came across this demo video of a 3D browsing experience created using WebGL, HTML5, Javascript and the Mozilla Audio API.  Is this the future of Web browsing?

I’m not extremely fluent in all of these technologies (for more info, see Flight of the Navigator), but as a demo, this is pretty impressive.  To me, it looks a little like Second Life with tons of screens out to the internet.  In other words, slick and different, but I’m not sure how useful, or even how truly integrated this experience would be.  Would you rather navigate to different places on the Web by moving through a 3D space or by Ctrl-Tabbing to the next open tab in your browser?  Maybe I’m old-school, but the latter seems far easier to me.

Of course, there are lots of other demos posted online and it will be interesting to see where this goes.  Checking your favorite Twitter feeds in-game would certainly blur the line between the gaming experience and the real world, but is this necessary?  Probably not, but maybe that’s not the question to be asking with whiz-bang technology like this.  It certainly opens up interesting avenues for the greater integration of a wide range of technologies.  Where that takes us will be interesting to see.

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.

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.

Optical Illusions

optical illusion

We’ve all seen optical illusions before.  Many of them, like the Ames Room above, take advantage of the flattening effect of the still camera, which only captures images from a single perspective.  But part of the fun is moving around to a different vantage point, which reveals how the eye is tricked.

Brusspup is an artist who has a YouTube channel that reveals optical illusions that he creates.  These videos offer the best of both worlds because the viewer can see both the illusion and how the trick is achieved.  Some examples are below.

How can these be used in the classroom?  Optical illusions are almost universally engaging.  Beginning with a still image of the illusion (or by pausing the video at that point,) students could be challenged to express how the illusion is created.  The class could then watch the video to see the solution.  This could be a fun and challenging way for students to formulate hypotheses and think critically.

Alternatively, students could be directed to the YouTube channel and asked to find their favorite illusion.  They could then be assigned the task of describing the illusion (both the effect and how it was achieved) in a presentation or in writing.  Depending on the level of the students, breaking down the task into step by step pieces would also be a good test of their English.

There are lots of other ways to use these videos.  Whether they are incorporated into a classroom activity or just viewed as an informal warm-up activity, they are sure to get your students talking.
