Reflections on Using Twitter in the Classroom

At the beginning of the term I embarked on a Twitter ‘exploration’ and described it as such to the class.  I’ve noted my Twitter skepticism and reluctant semi-conversion before.  The final push into this venture was inspired in part by a wonderful talk from Todd Zakrajsek at the Lilly South Conference in Greensboro, NC in February of 2009.   He spoke about the power of social norms and our role as instructors in sometimes reinforcing negative norms (“Where is everyone this morning?” –Todd’s example). While he didn’t mention Twitter specifically, as I designed the course, this technology emerged as a possible tool for promoting a community of readers and establishing a positive classroom expectation of preparation. A phone buzzing with an especially poignant comment from a classmate about an assigned reading, seemed like a potentially subtle and effective way of establishing a positive norm and sending the following message:

Not only are my classmates doing the reading well ahead of time, but they are thinking deeply about it.  I better get on it.

Twitter isn’t the only strategy for helping students engage challenging reading material. Bean and others have outlined some very effective strategies that I’ve borrowed. But it seemed worth trying Twitter as a supplement.

Before I summarize the students’ thoughts on the experiment (Students please let me know what I got wrong in the comments), I’ll talk briefly about the mechanics of setting up Twitter for class and how it was used in conjunction with the reading.

1. The mechanics – I set up a private Twitter group using GroupTweet. I liked this option because current Twitter users could keep their existing logins, rather than creating a new one for class.   If they wanted to send a Tweet unrelated to class, they could continue to do so.  If a tweet was directed to the class, they sent a direct message to the group, prefacing their message like so:

D ourgroup What do you think? Arkady p. 340 “Shortness of life was a primary force in the permanence of institutions …”

The setup was a little cumbersome.  Each student had to follow the group and also allow the group to follow them.  After everyone came to class with an established user account, we spent about 20 minutes setting this all up.  I think it was worth the class time, rather than trying to field questions online.  Many students also set up their phones for text messaging at this time.  I emphasized that this could all be done from the Twitter website and that a text plan was not necessary for completing this requirement.

2. Assignments – A bit of tinkering led us to the conclusion that a minimalist approach is best.  After asking the students to read five forensics articles related to the historical case and send two tweets about each, we all agreed this was counter-productive and too hard to track.  After that barrage, the typical assignment involved posting one comment and one question to classmates.  After a while, one question OR comment seemed enough.  More on that in a minute.

The results:

Positives

  • Convenience -  Several students commented that it was very convenient to send a text message when away from the computer.  When an idea struck them, they could share it at that moment.  My thirteen year old will attest to the fact that I don’t text much, but I sent quite a few thoughts to the group this way. One question hit me in the parking lot, and it was delivered to class before I got in my car.  No need to log on that night!
  • Social Norm – There was less agreement on this, but some students nodded in agreement when I indicated this exercise potentially strengthened our reading community.  During an especially busy week, I found myself a bit stressed when my phone started buzzing with student ideas and I hadn’t submitted my tweet yet.  By the time I posted, several of my thoughts were ‘taken’. We seemed to have set an unwritten rule that ‘original ideas were required’, so I had to look at the text from a different perspective—an unexpected but significant plus!
  • Length Restriction - Some mentioned being frustrated by the 140-charcter limit but others felt the constraint forced them to tighten up an idea.  All-in-all this tension seemed to be positive thing.  Many of the tweets cried out for more discussion during class.  I’m putting the character restriction squarely in the positive category, with a few, not insignificant, caveats noted below.
  • Connection – I felt much more on top of student perspectives prior to class after reading their tweets.  Their posts helped me prepare questions and plan for the upcoming discussion.  If there was an angle the students weren’t exploring in their tweets, I could pose questions in class that probed the issue more deeply. Their tweets also revealed some unexpected paths.  Yes, in-depth journals or discussion boards might have provided more insight and required more writing, but there just didn’t seem to be room for that with the other assignments and goals.  In the end, I was surprised at how much the tweets helped me get a gauge of student perspective in a very concise way!

Negatives

  • Forced syntax: While the character limit forced us to be concise, I felt like I was doing Edward Abbey a serious disservice when I tweeted his quote below.  The original goes like this:

“Anarchism is founded on the observation that since few men are wise enough to rule themselves, even fewer are wise enough to rule others.” – Edward Abbey

Here’s how I resolved to tweet the message under the 140-character restriction:

“Anarchism – founded on observation since few men are wise enuf to rule themslvs, even fewer are wise enuf to rule others.” Abbey

Yikes! Tweeting with misspelled words and truncated thoughts just bothers me.  Maybe I need to enter the 21st century, but there’s part of me that doesn’t want to let go.  Am I having trouble with the anarchy of Twitter?  Stop poking me Ed.  You’d hate this Twitter thing, wouldn’t you?  Perhaps Seldom Seen Smith, Bonnie Abzug, Doc Sarvis, and George Hayduke could have coordinated this way.  #monkeywrenching?  But I digress.

  • Linking: bit.ly and tinyurl do make linking easy, so beating the 140 character limit is possible this way.  I could have used these services to link directly to the Abbey quote above; however, if the reader doesn’t have a data plan, this click through is less likely to occur on a phone.  Tweets I get from the Mars rovers hit my phone this way, but since I don’t have a data plan or iPhone, I don’t click through when reading from my phone.  Most of these tweets turn out to be text message noise because the gist of the message is incomprehensible without the detail behind the link.  Reading from a different client (like TweetDeck) helps me stay connected to the latest news from the rovers (which almost always includes links), but text messaging alone doesn’t cut it.  Agreeing on a client and linking practice is key before implementing this in class.
  • Threads: The students were a bit annoyed at not being able to respond easily and in a threaded fashion to a particularly interesting post.  Twitter has reply syntax(@), but let’s face it, it’s not designed for threaded discussion.
  • Reading Classmate Posts: Many of the early tweeters for an assignment admitted that they weren’t going back and reading others’ tweets until we put them on the screen or passed them out on paper in class (the latter seemed more effective).
  • Delay: There was often a significant delay between when students posted and when the tweet actually displayed, which caused some dismay, since tweeting was a requirement for many of the readings.
  • Hashtags:  Initially, we thought hashtags would help us organize the twitter discussion, but for our purposes, they didn’t seem to add much.  They quietly dropped from the dialog during the latter half of the semester.

Final Thoughts

Rather than confirming my initial doubts about Twitter, the experiment highlighted the appropriate niche for Twitter in my classes.  I’m sure there will be more iterations, but here are my tentative conclusions:

  • Twitter is a great tool for giving me a glimpse into how the students are approaching the reading in a low impact way for both the students and for me.  This window (albeit blurry) helps me develop discussion strategies and questions for the next meeting. Student tweets are an excellent springboard for more detailed discussion and analysis.
  • Less is more.  A single tweet can lead to a good bit of discussion and analysis.  It’s a seed crystal rather than a finished product.  I was really impressed at the deep analysis behind some of the tweets we discussed. Asking for multiple tweets on a particular reading was counterproductive for us.
  • Additional strategies are needed to encourage students to read and learn from their classmates’ post.  Simply asking students to come in with 2-3 posts that interested them before coming to class seems like a possible way to encourage this vital practice.  Additional ideas??
  • Participants need to agree on how they will use links.  If text messaging is the primary delivery mechanism, I’d strongly suggest avoiding linking.  The tweet should speak for itself.  If linking is desired, utilizing a client such as TweetDeck probably makes the most sense for everyone.
  • If you’re looking for more than a catalyst for in-depth discussion, journals or discussion boards are a better fit.  Tweets are a beginning, not a final say.
  • Consider mixing in write-to-learn activities and other exploratory writing to provide students with an additional avenue (in addition to class discussion) to explore their ideas or prepare for class discussion.  Twitter is just one of many tools—including actually writing!

Okay.  I’ll do it reluctantly.  Summing up my post in a tweet …

Scrivener Rocks as a Course Design Tool

I mentioned in an earlier post how much I liked Scrivener as a writing tool.  As I used the program to write some learning goals for an upcoming course, I began to realize how powerful it is for facilitating the entire course development process.

Here’s a brief video demonstration which shows how I’m using it for course design as well as reflection and organization during the course.

scriv

While there’s only a Mac version available, Literature and Latte, the maker of Scrivener, has provided a list of supporting and alternative softwareWriteItNow is mentioned as an alternative for the PC, but I haven’t tried it yet.  Anybody out there have any experience with WriteItNow?

Visualizing the World – Wow!

This is a really powerful tool for viewing global statistics that might be useful for class.  The visualizations in Hans Rosling’s presentation  are pretty amazing.

Motion Map

The tool Rosling uses in the presentation is available online (along with his blog).  It took me a little while to figure it out how to use it, but experimentation with the maps and charts, along with the video tutorial, really helped me realize how much is here.

Indicators include health, economic, education, environmental, and more data from the UN.

The site also provides information about how you can use Google Spreadsheets to make your own motion charts.  I experimented, and the process is fairly straight-forward for charts but doesn’t include the mapping piece, which is available for the UN data on Rosling’s site.

Scrivener – A great tool for writing

What’s this demo about?

I wholeheartedly agree with Bryan Bibb’s great overview of Scrivener . Scrivener is an amazing tool for writers and allows for easy organization of a wide variety of resources. This tool has transformed my writing process!

Additional Detail:

The software is only available for the Mac. :-(

How long is it?

The overview video is fairly long but definitely worth the time to get a sense of what this software can do.

Geospatial Revolution Project

Now that spring semester is over, I’m hoping to pick up my blogging pace again. Penn State University announced the geospatial revolution project recently, which involves the creation of video episodes to explain the importance and role of geospatial technologies in our world. Check out the trailer below. This looks intriguing!

Whenever I try to articulate my excitement about the power of geospatial technologies for learning across the curriculum, I’m usually disappointed in my ability to convey the message. It looks like these episodes might do a much better job of highlighting that connection. I’m currently taking GIS courses through Penn State’s online program, so I recognize at least one of the interviewees in the clip!

Science Projects and the NFL

eyeblack experiment The upcoming NFL matchup between the Packers and the Giants on the frozen tundra of Lambeau field this Sunday helped my youngest daughter design an experiment for her upcoming science fair project. She’s been studying heat, so we’ve been discussing what Green Bay fans can do, if anything, to stay somewhat warm during the game.

I’ll share more details once we have data, but it’s the second NFL-inspired project we’ve undertaken in the last few years. The strange picture above was taken during experiments carried out by my oldest daughter when she was in second grade. We were wrestling with science fair project ideas and took a break to watch football when she asked, “Dad ,why do they wear that black stuff under their eyes?”. A visit to the wig shop (for the styrofoam head) and the sporting goods store, along with a borrowed light meter, provided the raw materials.

indoor eyeblack

We didn’t see a difference indoors or outdoors in the amount of light entering the eye, but she conjectured that the light meter doesn’t have the same kind of peripheral vision that we do. She didn’t use those exact words of course.

While we were experimenting, Ricky Proehl (pictured below), then wide receiver for the Carolina Panthers (and fellow Wake grad, I might add), was signing autographs at a nearby sporting goods store. My daughter took the opportunity to ask him a few questions, since he wears eye black. He admitted that there might be a bit of habit and superstition involved, but he felt it really helped him see better, especially indoors. He was really friendly and patient and seems to be a great a guy. We added the eye black with photoshop.

Ricky Proehl

More formal studies seem to suggest it helps with glare and contrast sensitivity and that the grease is better than the stickers. Plus it looks tough! That’s the real reason I wore it while playing high school baseball, since my hitting wasn’t going to impress any girls. I even remember swiping grime out of the tail pipe of my car before one game because I ran out. Gross.

Go Packers! With wind chills way below zero, light glare is going to be the least of the players’ worries this weekend.

Screen Draw Program

It’s been a long time since my last post. February was pretty busy. Last month during a presentation of some Google Earth features, I was wishing I had a tablet so I could scribble some notes and highlight some areas on the map. I found a cheap program for Mac users called desktastic that’s pretty simple and cheap ($12.95) that does a nice job. Here’s a shot of Mt. St. Helens where I jotted a few notes.

Mt. St. Helens
As you can see there’s a pencil, stamp, and text tool. Pretty simple stuff but useful. You can assign a key to toggle the program, so that it sits on top of programs or underneath.

Of course you can have fun doodling as well. I think Newton looks pretty cool with the mustache. ;-)

Can you count the passes?

Check out this video. See if you can count the number of passes between members of the team in the white t-shirts, and then read the post below.

Discussion on the Post Above

Did you watch the video from the post above? How many passes did you count between members of the team wearing white shirts? I counted 14. Did you see anything strange? If not, watch the video again and keep an eye out for the gorilla. You aren’t alone if you missed it. Over 50% of folks fail to see the person in the gorilla costume walking through the center of the action.

This is the example of inattentional blindness that I mentioned in a previous post. My colleague Dr. Larry Pace pointed me to the video. Here’s another page with some more examples. This is so fascinating. My favorite is the study where they ask a subject for directions and creatively swap the recipient of those directions. The study revealed that the more the recipient approximates the subject in age, etc., the more likely the subject is to notice the switch. The bigger the differences, the more likely it is that the subject will keep giving directions to a completely different person and never notice the switch.

This inattentional blindness can play a big role in poor decision-making in survival situations, according to the book I’m reading. Basically, if you’re lost in the wilderness with me, it’s best to ditch me as soon as possible. Your chances will improve! I wouldn’t have seen the gorilla if I hadn’t known it was coming.

This has so many implications for the relationship between learning and learning environments. I can’t wait to read more.

Learning in Retirement Blog Class

Yesterday I taught a FULIR (Furman University Learning In Retirement) class on blogging as part of Dr. Lipscomb’s What’s New in Technology Series. I’m really enjoying the opportunity to get back in the classroom, and this was a great group of folks – friendly and very curious, especially with regards to how this technology fit into the big picture. The initial discussion was fostered with some iClicker questions about experience with blogs and familiarity with the term ‘Web2.0’. After a quick overview, we jumped into creating our own blogs.

The time I spent on Friday creating WordPress accounts (wordpress.com) for each participant was worth it. We quickly started creating posts, and I think everyone enjoyed swapping out themes.

theme

Sample WordPress Theme

I’d like to see WordPress simplify adding pictures to a post. What if by inserting a photo into a post, it was uploaded behind the scenes, instead of having to upload, send to editor, etc..? We got through it, but the challenges highlighted the counter-intuitive user interface.

I think a decent portion of the class may keep blogging, based on the questions I was getting after class. Several wanted to know more about feedreaders, so they could consolidate the blogs they have been following.

A couple of things to do differently next time:

1. Track down some mice for the laptops. The trackpad was a significant barrier at times.

2. Provide more detailed, step-by-step instructions for adding / editing a post, and especially adding an image.

A couple of things to keep:

1. The clickers. This helped get a quick, anonymous gauge of experience level.

2. Directions on how to get to the admin panel. Many of the themes either make this link hard to find or remove it altogether, so having this in the handout really helped.

I really enjoyed this and might propose some classes for the spring!

One person commented as they left that they would explore this more the next time they couldn’t sleep. My blog started one morning when I was tossing and turning. I wonder how many blogs have started during a bout of insomnia??
