Image Size and Resolution

over stretched image

Think this image looks good? Click on it to see it actual size. Yikes!

I made a presentation at Ohio TESOL last week about how to make better PowerPoint presentations.  I’m going to add the audio to my slides by the end of this week (currently, you can only view the original slides sans audio).

Overall, the presentation was very well received.  In fact, I even inspired some people to overcome their fear and give PowerPoint a try.  One such brave soul emailed me the following question about blurry images, which I think is worth sharing here.  It’s a problem that many beginners face when adding images to PowerPoint presentations as well as print documents.  You won’t be an expert until you can fix it.  My response follows.

I loved your presentation last week on PowerPoint.  Being technically challenged, pp has never been at the top of my list to try.  But, after listening to you last Friday, I have put together a small presentation for a listening and speaking one class.  My question is…After I paste and stretch photos from Flicker, they are blurry.  I realize it is probably a simple click, but I cannot find it.  Please help!

I’m glad you enjoyed my presentation and I’m glad you’re diving in  and trying things out in PowerPoint.  I think this is a really good way to learn this technology.

image stretched 900%

Stretching an image to 900% of its original size will result in a blurry or pixelated image.

The issue you’re dealing with is a common one.  It has to do with the size and resolution of the original image you’re trying to add to your presentation.  When you are in PowerPoint, double-click on the image you’re working with to pull up the “Format Picture” menu.  Choose the “Size” tab at the top to see if you’ve stretched your image past it’s original size.  If the height or width under “Scale” is more than 100%, you will probably experience some blurriness or you will start to see all of the pixels that make up the image.  (To really see this, try using a really small image from a website and stretching it to fill your entire slide.  It will get really, really blurry and pixely.)

flickr picture

Click on "all sizes" to find larger versions of images in Flickr.

So, that’s the problem, but what’s the solution?  Well, you need to start with larger original images.  Once you find an image in Flickr, you will see an “ALL SIZES” button right under the title of the picture.  This will take you to the original picture and often give you several different size options.  By choosing the original, you can usually find a version large enough that you will be able to stretch it to fill your slide.  I suggest you double-check after you stretch it though (double-click again to pull up the Format Picture menu) because if it’s more than about 110% of the original size, your picture may look stretched when projected onto a screen even if you don’t notice any problems on your computer.

Something else to consider is the file size of the picture you use.  If you just need a small picture, try to avoid using the largest size.  Using larger pictures increases the size of the file for your final presentation.  While finding room on a hard drive usually isn’t a problem for new computers, on some machines PowerPoint can get bogged down and run slowly if many large photos have to be loaded for every slide.  So, if you only need a little picture in the corner, try using a smaller size image.

I hope that’s pretty clear.  Give it a try and let me know if you’re still having trouble.  Incidentally, I hope to upload an updated version of my presentation complete with audio in the next couple of days.  Watch for it here: http://www.slideshare.net/eslchill

Music in the Classroom

Technics turntable.

Drop the needle.

Next week I begin teaching a class that I designed called the History of English Language Popular Music Elective (HELP ME).  It’s a five-week class that will feature a decade of popular music each week.  The class meets every day and each day will feature a different song.  We will listen to the song, review and analyze the lyrics, and then listen to the song again and sing along.

There are many goals for this class.  First, it will expose students to songs that everybody knows to give them a foundation in popular cultural.  When a song comes on the radio, I’d like students to be able to say, “Isn’t that the Beatles?” just like a native speaker might.  The class will also include some linguistic content from each of the songs.  It could be a specific verb tense, idioms, pronunciation or whatever, but this will be an English class.  Finally, through the changing periods and genres of music, we’ll be able to talk about history.  Many changes in our culture are reflected in popular music.

Here are a few songs that I’ve identified for inclusion in the class:

All Shook Up by Elvis Presley – This song has lots of good metaphors and is a good example of an early rock song.

A Hard Day’s Night by The Beatles – There are some good examples of the present perfect in the chorus.

Paint It Black by The Rolling Stones – A Stones song has to be included, but many have very repetitive lyrics.  Paint It Black has lots of English to work with including colorful metaphors that students could be asked to interpret.  It could also be contrasted with What A Wonderful World by Louis Armstrong, which also has colorful metaphors.

I have a few others, but that’s a start.  Do you use music to teach ESL or EFL?  What songs do you use?  Share them in the comments below.  I’d like to know.  If there is enough interest, I’ll share my final set list once the class is finished.

Vorbeo: Easy Web Polls

Vorbeo: free and simple online polls.

Vorbeo: free and simple online polls.

Another recent resource that came across the Twitter stream (thanks @NikPeachey!) is Vorbeo, a custom online poll generator.

The most amazing thing about this tool is how simple it is to use.  The question, answers, and even the text for your “vote” button are customizable.  But, the best part is that there is a live preview of your poll that changes as you customize your poll.  When you’re finished, copy and paste the code generated by Vorbeo into your moodle or other web space.  Easy!

Making a poll with Vorbeo.

Making a poll with Vorbeo.

Now, you can poll your students, students can poll each other, and students can even poll the general public, if they can put enough people in front of the poll.

As an edupunk who likes to tinker with code on occasion, I also appreciate that the code changes as the poll is customize.  This is a great way to learn what each line of the code does.  (Incidentally, if you’d like to learn more about HTML, CSS, XML, and other scripting languages, try w3schools.com which has many examples and tutorials with live previews.)

Update: As slickly as Vorbeo generates web polls, it appears that these polls are not compatible with WordPress blogs.  Perhaps this is because WordPress already has it’s own polling feature using different technology or because it strips out HTML forms for security reasons.  Either way, trying to post a Vorbeo poll to a WordPress blog will neuter it (see below).  My other comments still apply, but check that Vorbeo is compatible with your application before counting on it in the classroom.

Do you like online polls?

Yes, the more the merrier!
Yes, occasionally
No, not really
No, I never respond to them!

Twurdy: Readability-Based Search

Twurdy = Too wordy?

Twurdy = Too wordy?

I came across Twurdy the other day and thought it was interesting enough to share.  In fact, I came across it on a blog post by someone that was recommend via Follow Friday on Twitter.  If I still had that electron trail, it would make an interesting story, but I don’t.

So, back to Twurdy.  This search enging is Google-based, but it also analyzes search results for readability using a proprietary algorithm.  The results are color-coded into the list of results.  If an item is determined to be easy-to-read, it is light in color.  Harder-to-read items are progressively darker in color.

Does it work?  I haven’t used it enough to be sure yet.  It’s certainly an intriguing idea, but the results will only be as good as the algorithm, the details of which are not shared on the Twurdy website.  But it may be a useful for learners with limited ability to start with the easiest-to-read pages or, conversely, for students to analyze the differences between easy- and hard-to-read texts.  I’m not suggesting students reverse-engineer the algorithm, but finding the features that make a page “hard-to-read” could start an interesting process that could aid students in their writing.

Making Friends at the Airport

An old extension cord makes new friends.

An old extension cord makes new friends.

Although I’ve kept this technology blog going for a little over a year now, I’m hardly a gadget geek.  Consequently, I’m not that guy at the airport juggling the laptop, cell phones, pda, digital camera, etc.  Perhaps it’s because I’m a bit of an edupunk: I like the challenge of hacking together affordable technology to wring every last ounce of usability from it.  Or maybe it’s just my lack of disposable income. Either way, I just don’t obsess over all the latest gadgets.

I do have a laptop that I use a lot, though, and I had it open in the airport recently when I found myself sitting next to that guy: He was pulling phone numbers from his laptop which he kept dialing to follow up with sales calls during which he made several references to the various cities and airports he had visited in the past week.

Of course he was talking loud enough for everyone to hear and of course he had two chargers plugged into one of the few electrical outlets in the boarding area for my gate.  I was planning to top up the battery in my laptop for the next leg of my flight, but there was nowhere to plug in.  What to do?  Easy.

A $5 commercial version.

A $5 commercial version.

I had brought along my three-way splitter which I cobbled together from an old three-way extension cord.  (I had used the long cord to make a formerly hard-wired flourescent light plugable and was left with this one foot piece to which I added a $2 replacement plug head.)  Of course, there are plenty of reasonably priced commercial options available, too.

I walked up to that guy, caught his attention, and gestured to my splitter and his chargers.  He gave me a quick be-my-guest wave and kept talking.  I unplugged one of his chargers, and plugged my splitter into the wall.  Into the splitter, I plugged his charger, my laptop charger, and the mp3 player of another passenger.  Instantly, I’m the life of the departure lounge.

If you travel with a laptop, cell phone, or other device that requires charging, bring one of these devices.  You’ll always have a place to plug in your charger and you might even earn some travel karma by helping out a gadget geek in need.

Professional Development 2.0

A network is all about making connections.

A network is all about making connections.

I’ve had a presentation called Professional Development 2.0 accepted to Ohio TESOL 2009.

The goal of my presentation is going to be highlight Web 2.0 technologies that can expose teachers to new resources and other people in the field.  I’ve posted before about the networked student, so why not the networked professional?

I’m going to focus on Twitter, because following the right people can set you up with a constant stream of great ideas and resources, blogs, which do the same but in long form, and RSS feed readers and other applications that can help organize all of these streams.  I’d also like to include Facebook, Linked In, Nings, and other social media, but I don’t have as much experience using them in the same way.

Among my own favorites are @LarryFerlazzo (and his blog), @TeachPaperless, @McLeod (and his blog), as well as blogs such as Six Things, Abject Learning, DigitaLang, and the others I have listed in my Blog Roll at right.

The purpose of this post, however, is to solicit other suggestions from you, the reader.  Is there someone you find especially useful to follow on Twitter?  Do you read any blogs that always inspire you?  Do you have a Facebook group that other ESL professionals should join?  Leave a comment below and share it with the world.

Writing 1000 Words

Tell me about your bus ride to school...

So, tell me about your bus ride to school...

Getting your students to write (or speak) can sometimes be a challenge.  They say a picture’s worth a thousand words, which got me to thinking: Where can teachers find interesting pictures that might prompt students to write or talk.  Here are some examples:

Photoshop Contest.com

Photoshop Contest.com

Photoshop Contest.com is a website that posts a picture each week for visitors to edit into other pictures.  The results can be fascinating.  The historical decoder device at right used this picture of typesetter’s letters as a starting point.  In addition to generating interesting pictures, trying to tease out which components of the picture are from the original can be an interesting challenge for students.

Worth100.com

Worth100.com

Worth1000.com is similar to Photoshop Contest with a variety of contests for beginning through advanced photo manipulators.  Although the results range in quality and interest, some of the theme categories could generate some interesting writing or discussion.  For example, the subjects in Sports Literalisms and Bald Celebrities may not be universally recognized by students, but Unsung Vending Machines and Less Than Usual require no explanation.  Some of the Literalisms provide interesting visual examples of idioms and other common English expressions.

Compfight.com

Compfight.com

Flickr is a very popular photosharing website.  And, although the sheer number of photos posted means it takes a little more digging to find them, similarly provocative photos can be found.  I often use Compfight.com to search Flickr because it’s very easy to select search parameters like Creative Commons licensed content and Safe Search.   Try searching for terms like manipulate, photoshop, and trick to find pictures that have been digitally edited.  Some, like the example of the car parked on the street have had no digital manipulation, but there is another trick involved.  Can you spot it?  Can your students?

Highlight the Web

Dont use these on your screen.

Don't use these on the internet.

I’ve recently started using Diigo to manage my bookmarks online.  It’s a lot like Delicious, which I’ve blogged about before, but has more features.  Both sites are cloud-based applications that allow you to manage your bookmarks online instead of in the browser of one computer.  So, instead of bookmarking something at the office and then not having it at home, or vice versa, bookmarks are saved to one central location.  And when I add bookmarks to Diigo, they are automatically added to Delicious, which means neither list becomes out of date.

The way I discovered Diigo was because of one of the features I like: highlighting.  Using Diigo, you can highlight sections of a web document and then forward a link to that page with the highlights (and even comments!) included.  For example, I could share this blog post.  This can be particularly useful with ESL students.  A long article may be intimidating, but a couple of paragraphs might be more manageable.

A simpler approach is a site called citebite.com.  You don’t sign up for an account, but instead copy and paste a URL and the section of text you want highlighted.  The site then gives you a URL for the result.  I could highlight this paragraph in this blog post, for example.  Comments are not available, and only one passage can be highlighted, but Citebite is a good, simple solution.

Awesomehighlighter.com falls somewhere in the middle of the other two applications.  When you enter a URL, you see the page and can then click on text you want highlighted.  Comments, in the form of sticky notes are also available.  Awesome Highlighter then provides a URL to your result page.  So, for example, I could add notes and highlighted passages to this blog post.  Unfortunately, Awurl.com, which Awesome Highlighter uses to provide URLs to the results pages, is blocked on the Ohio State network because it is a proxy / anonymizer.  Even though this is a localized problem, you might want to check that it won’t be blocked where you are before using this tool extensively.

The comment feature in applications like Adobe Acrobat, Microsoft Word, or other document editors has been used to facilitate collaboration between multiple authors and editors for a while now.  As we move closer and closer to the promises made by cloud computing, more and more of these tools are migrating to web-based applications that are becoming easier and easier to use.

Students Are Writing More

Our students are writing everywhere.

Our students are writing everywhere.

I recently came across an interesting article in Wired magazine about student writing: “The New Literacy” by Clive Thompson. The beginning posits that the new school year brings the usual fretting about how students’ writing is getting worse and worse. But Thompson then presents the most convincing counter argument I’ve seen yet.

Research conducted at Stanford University suggests that students (and people in general) are writing more than ever. All those text messages, Facebook updates, blog posts, and even classroom essays really add up. In fact, professor Andrea Lunsford is quoted as saying, “I think we’re in the midst of a literacy revolution the likes of which we haven’t seen since Greek civilization.” A generation ago, after leaving high school or college, how many people wrote more than a paragraph? Sure, there were some who were letter-writers, but we’re all emailers now.

The study also found that students are acutely aware of their audience and, in particular, adapting their writing to get their point across. Interestingly, students judge writing to be good if it has an effect on the world — if there is debate and interaction.  Essays are given less attention because the only audience for whom students are writing is the professor.

I don’t agree with all of the findings reported in the article (you may not either if you’ve ever received an email from a student that was startlingly informal — where is the audience awareness there?) but it does point us down an interesting path.

How much more attention do students pay to their assignments when their writing can be viewed by the whole class?  Or the whole world?  Collaborating on a blog or wiki for writing assignments makes this process relatively easy and straightforward.  What kind of feedback can they provide each other?  If the teacher adjusts her role to coach and helps guide this process, some feedback can be crowdsourced, giving students more responses.  Of course, student feedback would not be the same as teacher feedback, but both could be valuable.

Having students use new technology to share their writing is not a cutting edge idea, but this shift in perspective gives some insight into how blogs, wikis, and the like can increase production and, possibly, motivation.  Instead of lamenting students’ sloppy penmanship, maybe we should be embracing this revolution in writing and getting our students to write even more.

Crowdsourcing Meta-Resources

A Google Spreadsheet of TED Talks.

A Google Spreadsheet of TED Talks.

I came across a blog post on The History Teacher’s Attic which organized TED Talks by educational discipline and haven’t been able to stop thinking about it.  The interesting part is that the post is based on a Google Docs Spreadsheet containing information on every TED Talk through July 29, 2009.  The thing I like most about this post is the potential in this spreadsheet.

Johnny Lee's TED Talk introduces his $50 interactive whiteboard.

Johnny Lee's TED Talk.

First, most TED Talks are fascinating (Johnny Lee’s talk introduced the world to the Wii-based $50 interactive whiteboard) and authentic audio resources for advanced ESL students.  Having one central resource with overviews of all talks, is very useful for an ESL teacher.

Second, Google Docs can be very useful tools for collaboration.  Because they are cloud-based, anyone can access and edit documents via a web browser.  By opening up the document for anyone to edit, the work of compiling all of the information can be distributed to many people.  For example, this list of educators on Twitter spreadsheet was crowdsourced, meaning many people did a little bit of work to build what is a pretty extensive list.

The US Presidents mashup.

A mashup of US Presidents.

And once the spreadsheet has enough information, it can be mashed up in useful new ways.  For example, this mashup, created using MIT’s Exhibit, makes the information in the TED Talks Google Docs spreadsheet sortable and searchable.  Other examples include Flags of the World, which combines flag images from Wikipedia and a Google Map, and US presidents, which includes a timeline, map, images, and facts about each president such as religion and political party.

So, at this point, I’m ready to begin the new project of collecting and compiling some of my favorite resources into larger, crowdsourced, mashable meta-resources.  I’m going to start with a wide-open Google Docs spreadsheet, and then try my hand at different mashups.  But, before I begin, here are some questions I’m trying to answer.  (Feel free to supply your answers by commenting on this post.)

This American Life has great audio.

This American Life has great audio.

First, what resource(s) should be compiled?  TED Talks seem to be relatively well covered, but how about a similar resource for This American Life episodes, stories from The Moth live storytelling events, YouTube videos (EDU or otherwise), or other resources?  Should the meta-resource be targeted to ESL / EFL teachers or all educators?  And finally, what information should be included?  A link to the resource, the title, duration and a synopsis are obvious details, but what else?  Maybe keywords or tags as a way to organize them, the goegraphic location of where the story takes place, a warning system for language or content not appropriate for the classroom, and links to related resources in case students want to explore particular topics further.

So, consider this a call to action.  I’m going to solicit lots of feedback and then begin.  Once underway, I’m going to solicit more help.  With a little crowdsourcing, we can grow some really interesting and useful resources.
