Using QR Codes


A QR code is a user generated barcode that can be read by modern smart phones and are being used for a variety of purposes.  According to the QR Code Wikipedia listing, codes may contain text, URLs or other data.   Currently, one of the most common uses of QR Codes are in providing URLs (web addresses) for smart phones.  Usually the process goes like this:
  1. A creator of content publishes the QR Code using a variety of sources, with Google being the most common.   The web address (for example) is made into a bar code that looks like the one below:


      Village EduLand QR Code
  2. The QR code can then published online or even on printed media for the consumer of content
  3. Students or readers of the content can then take a picture of the QR Code with a free bar code reader app (for iOS) and automatically be directed toward a specific website emedded in the code
QR Codes such as this are increasingly being found in newspaper and magazine ads as well as in store offers such as at  discount and grocery stores.   The QR code is a easy way to convey especially long and specific website addresses to the public.

How do we make a QR Code?

The easiest and most accessible QR Code format for weblinks (URL) can be published by using the Google URL shortener called goo.gl.   Simply paste the website that you want to create the QR code into the text box as below:

After submission your URL will appear under the text entry box with several new options.  The first users will notice is that the primary purpose of goo.gl is to shorten long web addresses into shorter URLs that may be more easily shared.  Google also keeps track of how many people click on the shorted URL that can be published anywhere on the web and used like a regular web address.   

In order to access the QR Code we must choose the details link that brings up the following page:



How to Access the QR Code

As indicated above the final step is to save the image on your desktop for later use by right clicking and choosing ‘Save As’.

I have started using QR Codes in my classes as alterative ways to present long websites for students using printed and online material.   I still provide the actual link (or shortened goog.gl link), but for students using smart phones, iPod Touches or other devices with camera ability there seems to be allot of potential to be developed.   QR Codes could be used in the classroom setting to help develop scavenger hunts, puzzles, team building and other experiential activities.   


How might QR Codes be used in your classroom to improve learning?

EBooks in the College Classroom


I recently reviewed the 2011 Horizon Report that was published by The NEW MEDIA CONSORTIUM and the EDUCASE Learning Initiative.   The Horizon report introduces six technologies that will have a significant impact on learning and education in the next five years.  This year technologies highlighted include:
  • Electronic Books
  • Mobiles
  • Argument Reality
  • Game Based Learning
  • Gesture-Based Computing
  • Learning Analytics
Amazon Kindle App for Mac OS
For the purpose of this posting, I hope to spend time presenting ideas related to Electronic Books (EBooks) and my own experiences in the classroom.  Within my own EB supply closet are books from the Amazon Kindle Store, Apple iBooks Store, as the new Google Books Store.  Each store has its own unique strengths and decided weaknesses.

Also, my experiences with actual hardware include reading text via second and third generation Amazon Kindles, on smart phones such as the iPhone and Android as well the traditional computer and the iPad.   Again, each hardware experience has it’s own test case, and inherit pros and cons.

Within the classroom setting the least useful may be iBooks from Apple.   The catalog selection from iBooks pale in comparison to the other stores from Amazon and even Google.  The iBooks Store does at times have a better selection of specialty items (such as texts on Apple programming and software), but in general, the selection is much smaller.    Another negative is iBooks can only be read on iOS devices such as the iPad or iPod Touch or iPad.   Reading online or via your laptop is not possible at this time.  Prices for the iBooks Store is comparable to other online resources and special editions do exist with enhanced text and video for many books.  While a great start and addition to the online reading environment, Apple’s entry to EBooks has limited impact in my classroom.

A even newer option is the Google Bookstore, this new store is showing great possibilities for the classroom.   Google not only has one of the worlds largest collections of scanned books from libraries across the world, their databases include many of the same public domain books included in the iBooks and Amazon Stores.  Numbers of titles appear to be greater via Google while compared to the offerings from Apple.   Accessibility of Google Books are certainly greater with reading apps being available for iOS, Android, and for reading via web on a laptop or desktop machine simply by logging in your Google Account.  Most Google books are even readable on competing platforms (in ePub format) such as the Sony Reader or Barnes and Noble Nook.

The largest and most well known EBook platform is the Amazon Kindle Store.  Kindle is the format I use most personally and in the classroom setting for many, many reasons.   First, no one can come close to the options and catalog that of titles that Amazon provides to customers.   Second, the Kindle can be accessed almost universally, Amazon calls this the “Kindle everywhere”.   There are reader apps for iOS, Android, Blackberry, and almost every other mobile device.   Amazon also has special software for Windows and Mac OS X to read text on the computer.   Of course, as with the iBooks Apps, your reading placement and progress are synced across applications that makes sure whenever and wherever you read your book, your place is kept in the cloud.

While Amazon is clearly my favorite option due to ease of use, there are other features that the Kindle bring to the table that is quite valuable in the educational setting.  First, the notes tool of the Kindle editions is a great way to highlight important passages and and include personal reflections.   These notes and reflections can now be made public for any student to observe and read (with given permissions) online.  This means that as the instructor reviews the material within the Kindle environment, passages that have been highlighted and the notes of the instructor about specific passengers can automatically be shared with students online.   I think this concept of immediate sharing of text might be the most powerful and under appreciated aspect of the use of EBooks in the educational setting.  

A reported negative in the Horizon Report and other publications related to the use of EBook is the use of location numbers instead of page numbers.   Until recently within the Kindle environment, page numbers did not exist, only artificially created location numbers that were created by Amazon.   I have experienced this pain personally in the classroom when I was using a EBook version, yet my students were relying on page numbers I did not have.  The opposite is common as well, I only have the traditional paper copy of a text when the student has a EBook.   

Thankfully, as of last week Amazon is slowly rolling out a feature that provides page numbers for their EBooks. These page numbers will correspond to the page numbers listed on traditional printed texts.   If this system works as advertised, one of the biggest concerns of using EBooks in the classroom will evaporate.  

While this post basically ignores other competing readers from Borders, the Barnes and Noble Nook or Sony Reader, the foundational concept remains the same.  We as educators must pick the right tool, that will be accessible to the most people and presents the best information possible to students.    I have seen a dramatic number of students using EBooks in the classroom during the past year, thus as the Horizon Report indicates, we are beginning to see a shift from how course material is delivered away from traditional paper to electronic ink.

Favorite iOS App

I think my favorite iOS app of all time is Instapaper.  It is a simple app that is hard to conceptualize under one uses it.  Basically, think about the last time that you found something online that was interesting but there was no time to read the full page.  

This is Instapaper comes in.  Click on the installed bookmarklet on your web browser and the page is automatically saved to your free account in the cloud...minus ads and bad formatting.   The page is actually saved in a nice readable format minus distractions.

Then, with Instapaper installed on your iOS device (it is a universal app), download your pages for off line reading anytime you want in that same nice clear format.    So the bottom line is... the user can save almost any page they want for later reading and then see your list of saved items both online and via your iOS device.  

A sample of articles on my reading list....(via web)

Instapaper has implications for students or classrooms without iOS devices too.   The service can be used as a online bookmark for complete text.   Don't have your iOS device?  Just log into your online account to access your saved pages.   I see great promise for researchers or folks who like to keep online material of personal use at a later date.

Instapaper can be found here via the iTunes AppStore.

While there is no official Android App, a good unofficial program that is quite useable is InstaFetch.
