  • Best practices and tips for Twitter in the higher-ed classroom

    Fri, 2012-01-06 00:40 -- John Hawks

    College students have become used to instant communication. Many professors complain that technology has given their students short attention spans and poor study skills. Others bewail the end of civilization, as they see their students reading Facebook during class instead of taking notes.

    In reality, students are adapting to a new information environment. The cues that guided young academics to new ideas a generation ago were subtle, steeped in unwritten formalities, and exclusionary. Today, the best students are using social networks, feeds, and blogs to forage for the information that matters to them. But others will inevitably take advantage of the social buffet to browse away from your course's content.

    What to do?

    Try taking the reins, to meet your students at the information smorgasbord. Getting your students to interact with each other outside of class is one of the best ways to deepen their educational experience.

    Twitter is a tool that can enable ad hoc conversations and interactions among your students, in ways that you can track and foster. Your students may not all be familiar with Twitter, but its simplicity and availability, much like text messages on a phone, has a broad appeal.

    Curious about how to apply Twitter in your classroom? Or maybe you've tried it in the past but had only partial success. My list of suggestions outlines some of the most common questions and hangups encountered with Twitter among groups of students.

    I use Twitter in large undergraduate lecture courses, where participation is voluntary and happens in conjunction with other modes of communication. I have spoken to many who use it in smaller courses and who require students to use Twitter in certain assignments. These applications all have their distinctive features, but there are many commonalities that emerge in today's diverse student communities. Here are some of them:

    Learn to work in 140 characters.

    The absolute greatest thing about Twitter: It forces concision. If you're a blathering, droning lecturer who won't shut up, Twitter will show you the smackdown.

    Brevity runs a risk. Your course syllabus has bloated to include 3 pages of small print in legalese for a reason. After years of teaching, you've seen students misinterpret every clear statement in every conceivable way. Every tweet is like a grenade waiting to explode with mistaken misinterpretations.

    Solution: Edit, edit, edit. The key to effective tweets is setting them aside for awhile before sending. Make sure every word counts.

    If 140 characters seems like being chained in a box, try to find the freedom in brevity. When you read a great story, you can forward it to your students in a flash with no regrets and little explanation. Salt your tweetstream with items from your feeds in the morning. Let your students take the pulse of how a real expert forages for information. Or set up a list with some of the best tweeps in your field of study, and encourage your students to follow it. Leverage the power of the Twitterverse.

    Make the course hashtag part of the syllabus.

    As cool as you are, your students may not want to follow you. Besides, as cool as you are, most of your tweets have nothing to do with your class! Besides, Twitter isn't about your students following you, it's about enabling them to find information from each other. You need a hashtag for your course. A student who keeps a search on the hashtag will see every tweet, including those by other students. This keeps the conversation open because any student can chime in anytime.

    Picking a hashtag is easy. It should include the course number and something memorable or distinctive. For example, my Principles of Biological Anthropology course at the University of Wisconsin-Madison has the hashtag #uw105. Put it on the syllabus and show students how to use it on the first day. Give them a little handholding.

    Above all, when you've thought of the most awesome gangbusters hashtag, check first to make sure someone else isn't already using it. The last thing you want is to have your students confused because Unlimited Wrestling is using your hashtag for their 105-lb weight class.

    Students always have the option to reply to you or other students without the hashtag, taking the conversation to a more private sphere.

    Bring the feed into the classroom.

    The main problem with Twitter as part of a course: Most students may already have accounts, but don't use them. My first semester, I had only two dozen active tweeps out of a class of 240.

    Fortunately, there are many ways to leverage a small amount of initial engagement into a bigger interactive presence. Make an informal assignment to devise a 140-character answer to a question, and promote the best answers in class. When your students tweet a useful link, retweet it to your followers. Use the class hashtag to send informal study questions on the current readings, or preview the next day's discussion.

    One way to encourage greater uptake is to use Storify. Students can compile their tweets into a record of notes for the class session, or can use Twitter to put together a study guide for an exam. Because Storify stories are accessible from the web without Twitter, they also provide a way to show non-tweeps the value of Twitter in your classroom.

    Maybe the gutsiest use of Twitter is a live twitterfall next to your lecture slides. Giving your class a backchannel gives the students a voice even when they are listening to your lecture. My students have made great use of the backchannel during certain lectures, asking questions about the content that I can answer right during class. If you have a teaching assistant, you can task him to handle Twitter during lectures and alert you to questions; or you can watch the tweetstream yourself. But there's a risk: After all, when you give students a voice, some of them will use it to complain. Be ready to respond to questions, confusions, and complaints with good humor.

    Reward the students who are participating with attention. A daily pick of the top tweet, or a weekly top five, may be a real morale booster for certain students. Retweets are the currency of the Twitterverse, so use them liberally. Put your students into contact with other professional tweeps by mentioning them together in the same tweet.

    Be professional.

    If you spend a lot of time answering student e-mails, moving some of those questions Twitter can be a huge relief. An answer in 140 characters approaches the simplicity of handling questions in person at the end of class. But even though a tweet can be brief (or maybe especially because of brevity) you need to be conscious of your professional role in your class.

    All the usual advice about electronic communication applies to Twitter, too. Don't try too hard to be funny: Humor can easily go wrong in a diverse classroom, and in an electronic setting is often misinterpreted. Especially when the 140-character limit makes you omit words from the punchline.

    Twitter can help to level barriers in your classroom, but don't be too casual. You may be able to run your class effectively without formalities, but you are part of a college or department where not every instructor has your abilities. Don't unwittingly undermine your friends and colleagues.

    Don't assume your students are hanging on your every tweet, but be aware that some will cling to the barest scrap. A breezy tweet may mean little to you after you've written a dozen of them, but be conscious that a student may read those 140 characters just as they've spent most of the night studying for your next exam. Students may appreciate your quick and open communication style, but they are conscious of your power over their grades.

    Students in the U.S. are protected by FERPA, which limits the ways that coursework can be released to the public. That doesn't mean you can't assign graded exercises on Twitter, but you should be ready to justify your pedagogical goals: Is Twitter giving your students an additional way to communicate and synthesize content in the course, or do you expect that public communication is a skill they must master to be effective in your field? Anticipating possible outcomes for students is part of designing effective courses, and in this respect Twitter is adding a new twist to an old theme.

    Be prepared for abuse.

    Twitter is a public channel. Anyone who has tweeted much will have encountered spammers. Fortunately, bots and spammers usually don't tweet with hashtags, so they're unlikely to show up for students keeping a search on your course hashtag. But if you retweet your students' tweets, you should be prepared for the possibility that spammers find their usernames more than they would otherwise have done.

    Twitter makes it easy to report spam and block users. Making quick use of these facilities is often the most effective way to keep your students' timelines relatively uncluttered with spam. When you introduce Twitter to your course, you should always mention and highlight the ways that the service enables blocking other users.

    Because it's a public channel, one of your students may believe anonymity will protect him if he decides to be abusive. It's very easy to sign up for an anonymous Twitter account and a student can throw bombs into other students' timelines by including the course hashtag. An instructor needs to be concerned about the potential for cyberstalking or harassment, also.

    Fortunately, like other uses of technology in the classroom, your students' interactions on Twitter probably fall under your institution's electronic use guidelines. That means you have help from your IT department and college administration if you have a student creating a disruption. Don't think that an abusive student is solely a problem for your class: Electronic abuse and harassment are antithetical to a college's mission to teach students.

    A simple warning may be enough to let students know that anonymity will not protect bad behavior. Make it clear that electronic abuse is as serious or more serious than plagiarism. If you face a case of abuse that you suspect is caused by a student, inside or outside your classroom, make it clear to the entire class that the case will be dealt with by your institution's academic affairs personnel.

    A Twitter glossary:

    Tweet: The basic message, much like a text message on a phone. It's limited to 140 characters in length.

    Timeline: A series of tweets from people and lists that a user follows.

    Follow: By following another user or list, their tweets show up in your timeline.

    Tweeps: 6-character slang for followers and Twitter friends.

    List: A timeline can quickly become unmanageable if you're following hundreds of users. Including a set of related users in a list allows you to focus on content.

    Link shortener: Services like bit.ly or goo.gl take a long URL and give an equivalent that is 20 characters or less, making it possible to comment on links in a single tweet. Each of these services is essentially a huge database linking long URLs to short, customized ones.

    TweetDeck: Many users rely only on twitter.com or dedicated mobile apps for Twitter. Others use one of several software applications that manage Twitter content. Apps like TweetDeck automate certain tasks, like link shortening, and enable fast switching between concurrent searches.

    Hashtag: Any text string preceded by the hash (#) sign. Tagging a tweet with a hashtag helps to group tweets by subject. Searching by hashtag enables people to follow tweets from a course or meeting even if they don't know which users may be there.

    @: @ is a special character that let's Twitter know a username is coming (e.g., @johnhawks).

    Mention: A tweet that includes a user's @username. This shows up in the user's @mentions timeline.

    Reply: Clicking "reply" will compose a tweet that begins with a @username. This shows up in the user's @mentions timeline, but will not show up in your follower's timelines unless they also follow the @user you reference. Appending anything to the beginning of the tweet (like a '.') will make it appear in your followers' timelines, too.

    D: Twitter's private message option. If a user follows you, you can send them a direct message by D username. This will not show up in timelines of any of your followers.

    RT: The retweet. A basic way of relaying other people's tweets to your followers.

    MT: The "modified tweet". You can add a comment and edit other people's tweets to stay under 140 characters, and it's good form to include an "MT" to show that you've changed the original.

    Storify: A service (from Storify.com) that enables you to categorize a series of tweets and compile them with additional content into a narrative of an event.

    Other resources

    People are integrating Twitter into their classes all over the world, in many different academic settings, and they are sharing their ideas. Here are a few:

    "Professor Encourages Students to Pass Notes During Class — via Twitter": Jeffrey Young reported in the Chronicle of Higher Education about Cole Camplese, one of the first to use a live twitterwall alongside his lecture slides.

    "A Professor's Tips for Using Twitter in the Classroom": An even earlier article from Young, about David Perry's use of Twitter in an electronic communications class.

    "Twitter in the Classroom (this replaces those)": David Silver notes that Twitter replaces listserv, e-mail announcements, and serves as a way for students to share online assignments in other formats.

    "Twitter for Academia": Tips from AcademHack that go beyond the classroom and includes some ways that Twitter can actually promote good writing habits.

    "5 Unique Uses of Twitter in the Classroom": US News gave some interesting advice in their last higher education edition, focusing on ways that Twitter may benefit students beyond the classroom, and some very creative exercises.

  • In the lab of Shakhashiri

    Thu, 2012-01-05 21:09 -- John Hawks

    Nature this week profiles [1] my University of Wisconsin-Madison colleague Bassam Shakhashiri, now president of the American Chemical Society. Around here he is most famous for his activism in science education and outreach, which goes back many years. The profile discusses how Shakhashiri started in education:

    Science education should aim to share the beauty, challenges and rewards of open enquiry and help people to avoid sham, quackery and unproven conjecture. Interacting with students deepens my own understanding of science and of the process of learning science. When I joined the University of Wisconsin–Madison as a faculty member in 1970, my mission was to improve undergraduate chemistry education for all students, not just for science majors. In 1984, I became the assistant director for science and engineering education at the US National Science Foundation, after those programmes were almost phased out early in the administration of President Ronald Reagan. I rebuilt the programmes and created new ones. When I returned to the University of Wisconsin–Madison in 1990, I worked on science-literacy initiatives that focused on classroom instruction and the public appreciation of science.

    He gives an amazing show, full of chemical and physical tricks. It is so interesting how masters of science education and outreach leverage the advantages of their fields to find different ways to hit broader audiences. A chemist like Shakhashiri can do tricks like a magician on a stage; an astronomer like Neil deGrasse Tyson (recently profiled by Carl Zimmer) can take people on a virtual voyage through the universe. A physicist like Brian Greene can twist space or look inward to the smallest particles; a neurologist like Oliver Sacks can bring you on rounds to hear the stories of the strangest patients.

  • Blogs rank high in online education

    Fri, 2011-12-16 00:43 -- John Hawks

    This morning I read a notice from our Division of Continuing Studies, pointing to how their online resource library had received more than one million visits so far this year ("Vast distance education online resource open to all").

    With more than one million page visits to the UW-Madison Continuing Studies online Distance Education Resource Library so far in 2011, no one can dispute that interest in online education is flourishing.

    That is definitely something for the university to be proud of. But in breadth of outreach, I have a lot more impact writing alone here than the Distance Education Resource Library. Since the first of this year, my logs show 2.7 million visits here on this blog.

    Naturally, the audiences are not the same, and total visits is a misleading comparison, since our sites have traffic with a long tail of one-time readers, and a small cadre of repeat visitors. Thanks to every one of you!

    I don't track statistics like these to argue that one model is superior to another; they have different (and complementary) goals. Comparing the numbers is essential, though, because the comparison gives them perspective.

    Traffic is one way to quantify a website's importance, but it is most useful to compare traffic among sites with similar missions. Saying that "I had XXX visits," may sound very impressive, but showing how that number compares between credible and well-known web resources makes the number into useful information. A blog can do spectacularly well relative to a fully resourced education outreach project.

    MIT OpenCourseWare receives 1.5 million visits a month ("OCW Site Statistics"). Their offerings are uneven in quality, but they provide a unique service by archiving lectures as they are created.

    I am investigating the technology to offer substantial open course elements here on my blog. This semester I began offering our laboratories from a section of this website, and my lecture slides have moved to Prezi, making them easily sharable. After a semester to try out the new format, I think we may be ready to move onward with a full scale open courseware approach.

    So keep watching here over the next month, as I lay the groundwork for my spring course.

  • Medieval methods

    Tue, 2011-11-15 09:26 -- John Hawks

    Psychologist Alison Gopnik, in MacLeans "In conversation: Alison Gopnik".

    Q: What’s the traditional approach to learning at a university, and how does it square with what experts know about how people learn?

    A: The traditional way of thinking about learning at a university is: there’s somebody who’s a teacher, who actually has some amount of knowledge, and their job is figuring out a way of communicating that knowledge. That’s literally a medieval model; it comes from the days when there weren’t a lot of printed books around, so someone read the book and explained it to everybody else. That’s our model for what university education, and for that matter high school education, ought to be like. It’s not a model that anybody’s ever found any independent evidence for.

    Fri, 2011-11-04 21:41 -- John Hawks

    The New York Times devotes a long article to understanding why such a high fraction of students who begin science, technology, engineering and math (STEM) majors drop out of them in their second and third years of college.

    The National Science Board, a public advisory body, warned in the mid-1980s that students were losing sight of why they wanted to be scientists and engineers in the first place. Research confirmed in the 1990s that students learn more by grappling with open-ended problems, like creating a computer game or designing an alternative energy system, than listening to lectures. While the National Science Foundation went on to finance pilot courses that employed interactive projects, when the money dried up, so did most of the courses. Lecture classes are far cheaper to produce, and top professors are focused on bringing in research grants, not teaching undergraduates.

    I have an interesting experience with this problem. Getting students engaged with skeletal biology is really easy, because they can get started learning practical information really fast. This is a common pathway for students to enter biological anthropology. In genetics, in contrast, is has historically been harder to devise practical early experiences. First genetics courses are very much based on theory and memorization. Students who get onto a lab bench early are likely to stay very engaged. But many areas of biology today are most productively learned in other ways than the bench.

    I've been putting undergraduate students directly into bioinformatics, getting them working with data and presenting theory as it becomes useful to the project. This has been a really positive experience so far, and there are just countless opportunities today to get students working with the sea of data coming from next-generation sequencing projects. But there's not really much support at hand for developing these practical experiences for students -- that's something that hasn't changed since the eighties. Very hard to envision scaling up to a broader set of undergraduates, because a lot of supervision is necessary for these experiences.

    The article discusses piecemeal solutions, and more widespread ones adopted by some engineering schools for retaining first and second year students. Taking students who start out interested and engaged with science, and then treating the subject as "sink or swim", is a waste of everyone's time.

    The irony is that everyone already treats lab experiences as the only serious training for STEM students in many fields. Professors already bring undergraduate students into labs and spend time (and their graduate students' and postdocs' time) training them in lab experiences. They just use the lecture classes as an expensive and time-consuming IQ test to filter those students. But this has a real cost: Instead of developing expertise within the undergraduates, which might get some real work done, and at least allow senior students to train younger cohorts, they learn techniques only a year or two before they depart.

  • Hawks lecture at University of Birmingham Sept. 22

    Mon, 2011-09-19 19:25 -- John Hawks

    I'll be in the U.K. the rest of this week. The University of Birmingham has invited me to give a lecture for their "Great Read" event as they begin the new academic year. If you're in the area, the talk is at 3:30 on Thursday, September 22, in the Concert Hall of the Barber Institute. I'll be appearing after Ken Miller, widely known for his work in evolutionary biology and his advocacy of evolution education in the U.S.

    As for myself, I'll be talking about Neandertal and Denisovan DNA and what they tell us about human evolution. All my talks have new, unpublished stuff in them, and this is no exception.

    I notice that the topic of evolution education has really hit the news this week in the U.K, as a group of 30 prominent scientists, including Paul Nurse and Richard Dawkins, have signed a letter protesting lax evolution education standards ("David Attenborough joins campaign against creationism in schools", "Scientists demand tougher guidelines on teaching creationism in schools"). Looks like I'll be going there just in time.

    My host has planned some exceptional activities later this week for us, and I'll plan to report back when I can.

  • Mailbag: Textbook costs

    Fri, 2011-08-26 16:29 -- John Hawks

    Re: "Textbooks leaving students behind"

    Dr. Hawks,

    I am a long-time reader of your blog and a librarian at the University of South Florida. With interest, I read your comment of 8/24/11 concerning the high cost of textbooks for students and wanted to share some information.

    Here in the library we are taking it seriously and are leading an institution-wide effort to promote alternatives. There is some information concerning the library's Textbook Affordability Program (TAP) program at http://tap.usf.edu/. We've been encouraging faculty to develop open-access electronic textbooks (we will host them and assist with design/layout). We negotiated with the on-campus bookstore to donate copies of all textbooks with an expected user base exceeding 100 students to the library where we provide free access. We also have a VERY aggressive electronic book program that increasingly covers classroom needs. For context, our building holds 1.8 million physical volumes (the USF Library System holds 2.4 million) but our ebook collection is now approximately 600,000 volumes. Finally, we pay ~$140,000 to subscribe to a copyright clearance system that ensures that students no longer need to purchase expensive course packs and that faculty are protected as they try to help students.

    Thanks for mentioning this issue in your blog. I suspect that you caused some readers to consider solutions to this significant problem. And I appreciate your attention to such issues as peer review, the academic journal "ecosystem," and open-access.

    Cheers,

    Todd

    Thank you so much for writing with this! Yes, it's an awful problem, and my solution (write materials myself) obviously won't work for everyone. But maybe one step at a time we'll improve things.

  • Syllabus crafting

    Fri, 2011-08-26 12:49 -- John Hawks

    Barbara Fister, "The syllabus as TOS".

    These days syllabi are looking more and more like those Terms of Service that pop up when we use software. You know, the long documents in fine print with a scrollbar that we click through so we can move on. I thought nobody read them, but it turns out the excellent people at the Electronic Frontier Foundation actually track changes to them for us. (The EFF points out that these documents have a sinister side. They are contracts that we can’t negotiate, and they contain provisions we might not agree to, if we understood what they actually meant.) But the most striking thing about TOS is that they are full of rules – and very few people read them. So maybe they’re not the best model for the syllabus.

    Meanwhile, ProfHacker Jason B. Jones features some syllabi with graphic design appeal: "Creative approaches to the syllabus". Interesting to many readers will be Susan Sheridan's Introduction to Biological Anthropology syllabus, full of happy skeletons and visual appeal. Maybe the most stunning was the U.S. history syllabus from Worcester State University professor Tona Hangen, who describes her logic in "Extreme makeover, syllabus edition".

    I go with the single-page syllabus, myself, basically for the reasons Fister describes. I don't want any information to hide between the pages. But it's fascinating to see some of these creative approaches.

  • Textbooks leaving students behind

    Wed, 2011-08-24 10:44 -- John Hawks

    The Chronicle of Higher Education reports on a survey of nearly 2000 undergraduate students on 13 varied college campuses:

    In the survey, released on Tuesday by the U.S. Public Interest Research Group, a nonprofit consumer-advocacy organization, seven in 10 college students said they had not purchased a textbook at least once because they had found the price too high. Many more respondents said they had purchased a book whose price was driven up by common textbook-publishing practices, such as frequent new editions or bundling with other products.

    I find that the textbook is consistently the source of the most complaints from students on end-of-semester evaluations. I'm committing to no longer use textbooks that cost more than $10. I will use open access when possible.

    Think that's impossible? I don't.

    UPDATE (2011-08-25): See also my mailbag entry from Todd Chavez.

  • Administrative bloat

    Sun, 2011-07-17 01:58 -- John Hawks

    Mark Shapiro documents Parkinson's Law in action:

    For example, based on data in the California State University Statistical Abstract, the number of full-time faculty in the whole CSU system rose from 11,614 to 12,019 between 1975 and 2008, an increase of only 3.5 percent. In the same time period the total number of administrators rose 221 percent, from 3,800 to 12,183. In 1975, there were three full time faculty members per administrator, but now there are actually slightly more administrators than full-time faculty. If this trend continues, there could be two administrators per full-time faculty in another generation.

    Interesting is the breakdown of "managerial and professional" which has bloated extremely, compared to clerical, service/maintenance, and technical jobs, which have actually declined significantly over the same period.

    You know, if we could get these professional administrators to actually help in the lab and the classroom, I wouldn't mind having two of them working under me. Sadly, it doesn't work that way!
