Take out those cell phones in class

Andrea Novicki — Thu, 05 Nov 2009 14:52:45 +0000

Most students have cell phones, and more than half of all US undergraduates own an internet-capable handheld device and more plan to purchase one in the next 12 months (ECAR Research Study 2009). Why not use them?

How? Here are three ideas:

Cell phones and internet-capable phones can be used as polling devices, like clickers, to engage students during class. Poll Everywhere will supply an easy to use interface for small classes for free, or large classes for a fee.

Students could access information during class, to contribute to discussions or to inform critical thinking. How? Students could query Google or Google Scholar, access the library or librarian, use news sources, or specific applications for your topic.

Leverage student interest in texting to learn about their thinking during class, by setting up a backchannel, like Hotseat at Purdue University. A teaching assistant or other instructor can monitor the backchannel, and alert you to questions, problems, and student interest at appropriate points in the class.

Come to a discussion of using mobile devices for education, both in and out of class, on the second Tuesday of each month.

The next wave of e-readers

Randy Riddle — Tue, 29 Sep 2009 16:16:41 +0000

Last year, Amazon made headlines with their release of the Kindle, a new generation of portable e-reader that uses E ink, a low power display technology that mimics the look of a printed page. The screen isn’t backlit like a computer display.

Since that time, interest has grown in the Kindle and similar offerings from Sony and we’re seeing a new generation of devices that add functionality, increased screen size, and partnerships with publishers to provide content for the devices. Some are predicting that the hot electronics item this holiday season will be the e-reader.

Sony is offering three models this year. The Reader Touch Edition is a thin, touch screen version of the device selling for $299. An included stylus can be used for highlighting and annotation on the 6″ screen. The Reader Pocket Edition, priced at $199, has a 5″ display and is a kind of “entry level” model. Due for release sometime in the next couple of months is the Sony Reader Daily Edition, which includes a 7″ touch screen display and adds wireless capability, mainly aimed at downloading news content.

The most well publicized and largest selling e-reader to date is the Amazon Kindle. The Kindle is notable for being a wireless device, which operates independently from your computer – you browse for content at Amazon’s e-book store and download material directly using a wireless technology that uses a cell phone network. If you want to read your own documents – PDF files or Word documents, for example – you email them to a special address and they are converted and downloaded to your Kindle for a small fee. The cost of wireless access is hidden in the cost of a book or document conversion.

The Kindle is available in two models. The Kindle DX, selling for $489, features a 9.7″ screen while the latest version of their entry level device with a 6″ screen sells for $299. The Kindle allows for annotations using a small keypad on the device.

Philips is introducing a new version of their iRex Reader, the DR 800 SG, in October. Priced at $399 and featuring a 8.1″ screen, it includes a stylus that can be used for adding annotations. The iRex is wireless using cellular network technology similar to the Kindle. For content, Philips is partnering with Barnes and Noble for e-book offerings.

Just announced is an offering from Barnes and Noble – the Nook. This e-reader has some features in common with the Kindle – access to a large library of titles for purchase through their bookstore, availability of subscriptions to newspapers and magazines, and wireless connectivity. The Nook also includes a touch sensitive color lcd screen along the bottom of the device that can be used for controlling options, selecting books, or entering notes with an online keyboard. One distinctive feature of the device lets you “check out” books to friends using a Nook.

There are two clear models that have emerged for content on e-readers. Amazon’s using a “closed” system – you can only download books from Amazon’s site and have to do a conversion to get other documents on the reader. All of the Sony models and the iRex support EPUB, an open format for digital books, so you can download books from independent authors and publishers or public domain material from Google Books. You can also create your own EPUB formatted documents with several online or desktop tools and EPUB files can also be viewed in e-reader software on other devices – laptops, netbooks, or even the iPhone.

Both Sony and Amazon offer programs for authors to self publish. Sony has a partnership with Smashwords while Amazon’s service is called the Digital Text Platform.

For faculty that are interested in using electronic books in the classroom, the main issues with ereaders are availability of content applicable to your course and whether your students have an e-reader or other device capable of displaying the file.. Both the Amazon and Sony e-book stores concentrate on current best-sellers and older catalogue titles in the areas of genre fiction, business, popular history and hobbies. Some textbooks are available for both devices.

The market for e-readers and e-books is small, but growing. Faculty that use primarily public domain texts or assemble a textbook and readings from documents available on the Web might find the use of PDF and EPUB files useful in courses – both formats can be viewed on a wide range of devices including e-readers, laptops and mobile phones.

Through our exploratory equipment loaner program, the CIT has an original Sony Reader and Amazon Kindle that can be checked out by faculty.

Explore cell phones in teaching

Andrea Novicki — Mon, 28 Sep 2009 12:52:37 +0000

Meet with other Duke faculty and talk about ideas for using cell phones (or any small, mobile devices) in teaching, both in and outside the classroom.

At a previous meeting, participants discussed using these devices in class to engage students and foster interaction. Owen Astrachan demonstrated how he used Poll Everywhere with his class of 344 students. Poll Everywhere allows students to use their own devices as personal response systems, to give answers electronically in class.

Other participants discussed using applications that provide information relevant to the course, like Epocrates for accessing drug information, Labs 360 as a medical laboratory guide, or other applications for medical students. Other examples might be using the mobile version of the Wall Street Journal in a business class, flash cards for organic chemistry reactions, or spreadsheet applications for laboratories.

We discussed how instructors could incorporate the social networking and connectedness of applications like Smule’s Ocarina to engage students, and how Twitter could be used to build a community of students in an educational program.

EtherPad: real-time collaborative writing

Shawn Miller — Fri, 25 Sep 2009 13:37:43 +0000

A Mashable blog post listing “15 Essential Web Tools for Students” includes several tools that faculty may also find useful. We’ve written about Evernote, Delicious, Zotero and even Google Docs before (and they’re all a part of our Web2.0 Toolkit). One newer web app mentioned in the post is worth noting: EtherPad.

At first glance, EtherPad is not too unlike Google Docs – it’s also an online word processing tool of sorts. However, even though Google Docs allows collaboration with others (by sharing and editing the document), it only allows one user to edit the document at a time. EtherPad allows collaborative editing by several users in real-time.

EtherPad is still relatively new, meaning the editing features aren’t exactly robust – but when you’re doing collaborative writing, getting ideas down quickly is more important that the final formatting and markup. Word, HTML and text files can all be imported into a “pad” or you can just start from scratch. Pads can be exported in various formats (text, PDF, Word, etc), and there’s even a nifty “time slider” feature that can “play back” all the edits via a timeline.

No doubt, those teaching writing courses, or other courses that need to be able to capture rapid text-based collaboration, have been waiting or a tool like this. Here’s the catch:

Pads are free and public by default. You can invite anyone else by emailing them a URL (they don’t even need an EtherPad account). The downside here is that the Pad is public and anyone could potentially view it.

Free, public pads are limited to 16 users. That’s 16 users at the same time. Here in the library, we recently used Etherpad as a way to collaboratively construct notes during a guest speaker’s session – the only problem being that more than 16 people wanted to add something and basically had to wait until someone one of the other 16 users would “leave” the pad

Want privacy and the option for more users? EtherPad has a “pro” version available.

NOTE: If you’d like to try EtherPad, you can try it by editing the document in the screenshot (the text of this blog post).

Talking about Tweeting – DDI Twitter Lunch

Lenore Ramm — Wed, 23 Sep 2009 21:46:12 +0000

Earlier in September, several of us met as part of the monthly DDI Twitter program brown bag lunch discussion series. One of the overall goals of the program is to encourage a few faculty members to actively use Twitter in their courses, but another goal is to have meaningful discussions among interested faculty on academic uses of Twitter.

After introductions, I provided a list of potential uses of Twitter in a course (below). We discussed everyone’s ideas for using Twitter, which ranged from trying out Twitter in a language class to tweeting as an entire discipline to develop its community. Attendees were concerned about privacy, as far as FERPA and HIPAA, and representing the university as an institution. Attendees expressed a need for Duke to have an explcit social media policy, without stifling its use. Despite perceived complications, there was a lot of excitement about potential for spontaneous student participation, particularly from those who are more introverted. I also demonstrated two Twitter clients for following a large volume of tweets, Tweetdeck for the desktop and the web-based Tweetgrid. Two additional discussions sessions have already been scheduled for this fall, so you can register now.

Use cases for which all students would need a mobile device, laptop or be in a lab during class:

Polling each student within class
Participating in a class “back channel,” which would consist of lecture summaries, commentary and questions

Use cases for which a portion, but not all, of students would have access to a mobile device or other computer during class:

Tweeting in groups of 3 to 5 students where the tweets reflect the group consensus following a discussion

Use cases for which students would have access to a mobile device, laptop or desktop machine outside of class:

Students could receive information tweeted by the instructor and/or teaching stafff on course administrative issues and reminders.
Students could receive tweets from the instructor and/or the teaching staff on course related topics.
Students may tweet containing links to course related research.
Students may tweet reflections on course materials and course related topics.
Students may search for tweets using course related keywords or follow relevant #hashtags (e.g. #iranelection)
Students may follow experts in the course discipline or pertinent public figures.
Students may use Twitter to conduct interviews with one or more followers.
Students may tweet notes from course readings.
Students may tweet field observations or lab results.
Students participating in service learning could communicate from a remote location and record observations or reflections.
Both students participating in remote service learning or study abroad could use Twitter to maintain a connection with their classmates or advisers on campus.
Foreign language students may tweet in the course language and follow Tweeters from their respective countries.
Students may tweet to request help from classmates, the instructor or teaching staff.
Students may tweet creatively, taking advantage of the 140 character limit in order to condense a large idea into a brief statement (e.g. literary works, world religions described in a single tweet)
Students may do research using tweets as data.

Screen recording and Chinese character input in Apple’s Snow Leopard

Randy Riddle — Fri, 18 Sep 2009 14:44:44 +0000

Apple has released their new operating system for the Mac, Snow Leopard.

The update isn’t for everyone - it only works on newer Intel-based Macs and, since this is a major rewrite to the operating system, it has had some glitches on some computers and isn’t compatible with some current Mac software.

However, it gives you a glimpse of some new features that will be common on the Mac that will provide some useful options for you and your students.

A new version of Quicktime has a redesigned interface and simplified options for saving videos. One of the most intriguing new features in Quicktime X is a built-in screen recording utility, allowing you to make a video of your computer screen. Here’s a YouTube video demonstrating screen recording in Quicktime X.

If you work with the Chinese language, a new feature of Snow Leopard might be useful – input of Chinese characters using the computer’s trackpad. The YouTube video below shows a demo.

If you’re interested in investigating Snow Leopard, talk with your local technical support staff to see if the upgrade is for you.

Teaching with Twitter

Lenore Ramm — Wed, 26 Aug 2009 21:32:40 +0000

It’s hard to go anywhere or listen to anything without hearing something about Twitter these days, but how does it apply in an academic setting? Can the same technology that was used to communicate during Iranian political protests, following their presidential election, be used to help students learn?

You and several other faculty members can explore that topic during monthly brown bag lunch sessions. We’ll talk about ideas of how Twitter can be used in your course and look at tools that can make using Twitter for teaching easier. The first one will be on September 10th at 12pm.

Education calling – teaching with cell phones

Andrea Novicki — Mon, 24 Aug 2009 13:49:58 +0000

Now that many students carry a single device that can make phone calls, take pictures, record audio and video, store data, music, and movies, and interact with the Internet, how can we use this in teaching? This fall, meet with other faculty to discuss and test ideas and software for using cell phones or other small devices in teaching. We’ll meet once a month, for demonstrations and discussions. Come and share your ideas and learn.

On Tuesday, September 8th at 10 am, we’ll discuss topics and ideas for this semester. In addition, Owen Astrachan will talk about his plans for using Poll Everywhere, a simple polling system that uses student cell phones as “clickers” to gather student responses. We’ll try it out. Sign up to join us!

14 tweets that demonstrate the professional value of Twitter

Shawn Miller — Mon, 13 Jul 2009 21:55:47 +0000

Guest post by Julie Reynolds, Duke University

Twitter posts are limited to 140 characters, but I discovered it takes slightly more than 140 characters to convince colleagues of Twitter’s value. I’ll try to make my argument for why professionals should use Twitter, and I’ll do it in just 14 tweets. Here we go.

#1) Professional use of Twitter 1 of 3: Post URLs for blogs, articles, & events that you want to make public to a larger audience

#2) To promote publications, ex: “When Communicating with Diverse Audiences, Use Velcro to Make Science Stick http://bit.ly/4GD4fX“
#3) To publicize students’ work, ex: “#DukeEngage interns turn dung into fuel in India http://bit.ly/c3u1a”
#4) To publicize events, ex: “Citizen Science Training Opportunity July 19, 2009 http://bit.ly/16NYgc”

#5) Professional use of Twitter 2 of 3: Network w/folks who share interests or are using similar pedagogy/technology/research method

#6) Networking tip: be sure your Twitter profile has a descriptive bio so people can find you, ex: http://bit.ly/Vqepp
#7) Twitter can be like a virtual business card. Be sure your profile bio and webpage are up-to-date and informative
#8) Join a twibe to find similarly-minded people. Visit http://twibes.com/ to search and join twibes
#9) Add yourself to http://wefollow.com twitter directory so people can find you (I use #scientist #conservation #educator)
#10) I posted ex of students’ use of edu software, was contacted by software maker to ask if they could showcase my students’ work!
#11) Retweet to share info & build community, ex: “RT @saprasanna: Our DukeEngage project is on Duke News: http://tinyurl.com/nmuxkz”
#12) Search for keywords http://search.twitter.com/ (or via Tweetdeck, my fav Twitr app) & follow people who have interesting tweets

#13) Professional use of Twitter 3 of 3: Back-channel conversation at conferences for feedback on talks & updates on things you missed

#14) Ex: search for #NECC09 for examples of rich conversation and information resulting from back-channel conversations at a conference

You can follow this conversation on Twitter by searching for #TwitValue. For professional updates, follow Julie at http://twitter.com/JulieReynolds88.
