Student Writing for a Global Audience

by Steve Taylor

It may be humbling for instructors to realize that they don’t necessarily inspire the highest quality of writing from their students. Of course, students are motivated by grades to submit good writing to their teachers, but many have found that the prospect of students having their papers read by their peers can be even more motivating. For years now, many instructors have had their students upload written assignments to a shared digital space and found that the expectation of that sharing significantly improved the quality of writing.

The ante is now raised, as some instructors require their classes to share their writing with the whole world, via a publicly accessible website, such as a blog. These students know that they not only have to assemble sentences well enough to avoid embarrassment among their classmates, but they have to get their information right or risk being called out by any number of experts in their topic.

Publishing to the world is more than just a challenge not to fail, though— it’s also an opportunity for students to put themselves out there as legitimate, albeit novice scholars. Instead of paying several years of dues in graduate school before daring to submit a bit of original work in a peer-reviewed scholarly journal, they’re publishing now, and getting feedback as well.

At an ACS symposium this fall, Profs. Lisa Paravisini and Jenny Magnes spoke about these and other benefits of student blogging. “If you define your assignment topic well,” Lisa said, “having students publish their writings to a blog ups the ante, in terms of audience. The potential audience is the world.”

Lisa Paravisini-Gebert

One assignment she uses is to have students completely re-write a Wikipedia article. Their research must be thorough, accurate, ethical, and original. Sometimes earlier contributors to an article will immediately undo the submission; other times, it will remain and possibly generate some discussion among different contributors.

It’s even more interesting for a student to be able to publish original material, something that’s more feasible than most people realize. Students in Lisa’s environmental studies project photographed and interviewed people adjacent to the Casperkill Creek and blogged their work. What they shared was unique materials, of interest to a potentially wide audience.

Jenny Magnes

Jenny Magnes assigned her students to propose and execute a simulation project related to electricity or magnetics. They had to write a proposal, then a plan, create the simulation, and finally post their reports on the blog, along with their data files.

All of it was original work. Jenny browsed the web to make sure none of the proposed ideas were already posted somewhere. Each student had to make substantive, constructive comments on each others’ posts. But classmates weren’t the only ones responding.

One of her students did a project on induction (as in induction ovens), including one video that she made and one that she found on YouTube and several simulations, depicted with thoughtfully designed graphs.  One of the reader comments was from an upstate firm that does work similar to what she had simulated— the student was invited to visit the plant and speak with the engineers!

Lisa has also seen some surprising responses to blog posts. In her own blog about Caribbean Studies, she mentioned some of Sean Penn’s work and promptly received a comment from Mr. Penn’s assistant. One student posted a critical analysis of a book and heard back from the book’s author!

As Lisa says, online publishing brings a sense of responsibility to students’ research methods; they have to carefully consider issues of integrity, ethics of attribution, and originality. Because you never know who might be watching.

Farewell to Blackboard!

by Steve Taylor

For almost ten years, Vassar faculty and students have used the Blackboard system for sharing files and communicating within their classes. As we ring in the new year and ring out the old, Blackboard is one of the things we’re leaving behind. Here’s a little background on how we got to where we are.

By the late 1990s, many faculty members were learning HTML and creating websites for their courses, but quite a few colleges and universities had begun using “course management systems” or “learning management systems” to give their faculty an easy way to make course materials and activities available to their students online. There were a number of competing products— Blackboard, WebCT, Angel, “Web Course in a Box,” CourseInfo, First Class, WebBoard, and others.  I was interested in this development, but decided to wait a bit and see how the competitors fared.

By 2001, it was clear that Blackboard would become the dominant product in the marketplace. Since so many dot-coms were dying early deaths, that seemed a good enough reason to choose Blackboard. I approached the Director of CIS (Diane Balestri) and proposed that we adopt Blackboard. She wasn’t convinced about the prospects of this new technology, but suggested that if I could purchase it with my existing budget, we could try it. (Luckily, the initial offering was cheap.)

In the fall of 2001, we had our initial trial— about a dozen instructors used Blackboard for 19 courses. (More than a third of them were Chemistry courses.) Blackboard’s use grew dramatically:

There were a fair number of complaints about how Blackboard functioned, but Blackboard Inc. was very poor at responding to suggestions or even bug fixes. And the cost had grown to more than $40,000 annually. So in 2008, we began exploring alternatives and eventually decided to replace Blackboard with Moodle. Moodle is an open-source program, which means that anyone can customize the program to their liking. At Vassar, we’ve taken advantage of that by adding and removing functions, clarifying wording, creating our own look and feel, etc.

As of fall 2010, no active courses were using Blackboard, but the server was still available for instructors to access old sites. As of December 31, the server has been shut down. (ACS maintains archives of all Blackboard course sites, which can be imported into Moodle at any time in the future.)

Moodle has been enthusiastically welcomed by many, but the transition has not been easy. Once everyone is fully out of the transition stage, though, I think they’ll be quite happy with Moodle. And if there’s anything we don’t like about it, we can probably change it!

Videoconferencing

by Steve Taylor

Not long ago, the idea of live two-way video communication seemed futuristic. For years, phone companies dabbled with video-enabled telephones, but the bandwidth of a telephone connection just isn’t up to the job. With the nearly ubiquitous high-bandwidth Internet connections of the present day, however, one-to-one video conversations  via computer have become commonplace.

By far the most common system for this at the moment is Skype. Skype began as an Internet-based phone system (“voice over Internet protocol” or VoIP), but in 2006, added video capability. You can use Skype to connect to someone’s standard telephone (without video, of course), but there is a charge for that. When communicating Skype-to-Skype, voice-only or with video, there is no charge. That’s true for international calling, too, which is especially compelling, given the cost of traditional long-distance phone calls.

Apple’s iChat program also supports videoconferencing, including multi-party conferences, but only operates on Macintosh computers.

In education, one powerful use of videoconferencing is for a class to be able to converse— in real-time— with a highly regarded author, artist, or scientist, for whom it would not be practical to arrange a site visit. Children in elementary schools use videoconferencing to chat with authors of their favorite books.

Vassar students in Prof. Jeremy Davis’ Experimental Animal Behavior class used Skype to interview authors of articles they were reading. Students would read several articles by a single scientist, then prepare some questions. They would discuss the papers in class, then call the author, to ask their questions. Both students and scientists enjoyed the experience.

Since most recent-model computers have built-in cameras and microphones, Skype is easy to use for one-to-one videoconferencing. Using it for one-to-many conferencing is more difficult. Although it’s easy for a class to see and hear the remote person via a classroom’s projection system, the classroom computer’s built-in camera and microphone don’t work well for a room full of people. With funding from the Fergusson technology fund, Prof. Davis purchased a conference microphone, which made it easier for the class to speak to their remote scientists.

Another way to use videoconferencing in education is “many-to-many,” in which one class interacts with a remote class, often in another country. This technique has been used by Prof. Silke von der Emde’s German classes and Prof. Hiromi Dollase’s Japanese classes, to share knowledge with students in other cultures.

This type of videoconferencing calls for a more sophisticated system. There is a special communications protocol (H.264) that enables high-quality, real-time video and audio communication, but must be done using a specially designated device, rather than a standard computer. Many colleges and universities, as well as hotels and conference centers, have rooms with these devices. Vassar has such a system in College Center Room 204. A centrally located microphone picks up voice from anywhere in the room. The videoconferencing device— located above a 50-inch LCD display— includes a video camera that can be pre-programmed to pan and zoom to a dozen different locations in the room, so that the remote viewers can see the individual who is speaking.

In order to make use of Vassar’s videoconferencing facility, you’ll have to reserve the meeting room via Campus Activities and arrange for an operator via Media Resources. It’s advisable to arrange for a test-run previous to the conference day, to make sure that everything works on both ends.

Vassar’s newest player in this field is Adobe Connect Pro. Connect Pro is essential a web conferencing system, which is to say, a system for sharing computer screens and text chatting, which has for many years been used as a way to provide training or product demos to groups. But Connect Pro also includes voice and video channels and the ability to record sessions for later playback.

Please contact your ACS liaison to get started on any of these systems.

The Teaching and Technology Forum

by Steve Taylor

Though it’s not a recent event, I thought it would still be worthwhile to write about last spring’s Teaching and Technology Forum.

In its eighth year, the forum is a poster session in which faculty members display and explain teaching initiatives (or in some cases, research initiatives) that make interesting use of technology. A new feature this year was the inclusion of some student-initiated projects as well.

Keynote Speaker
A special feature of the forum is its keynote speaker. This year’s keynote was Prof. Paul Ruud, of the Economics Department. In his address, he proposed a new blog, in which Vassar  faculty members would regularly post brief descriptions of their class activities. With a high participation rate, this blog would let any instructor know what his or her students were doing in their other classes; then the instructor might adapt some lesson plans to complement what students were doing in some of those other classes. It might also encourage faculty members to communicate more with each other, based on a greater awareness of what each other was teaching. The result could be a strengthening of the cross-discipline integration that is the core of a liberal arts education.

The poster sessions, while quite diverse, covered topics that might each be considered to be one of two types: those that used technology to visualize information and those that use technology to increase social networking.

Visualization Technologies
Some poster sessions show ways in which technology could be used to give students greater access to images of what they’re learning about. Lucy Johnson, with Anne Sando (2010), showed how they are building a database of photos of the archaeological artifacts; Arden Kirkland and Holy Hummel showed how they are building a database of photos of the costume collection; Andrew Tallon showed his growing collection of digital 3D panoramas of architectural sites; and Sarah Kozloff showed how she is using streaming technology to provide students with anytime/anywhere access to film excerpts. Jane Parker showed a novel use of video for skills training: projecting video of a skilled squash player onto the front wall of a squash court, for players to mirror in real time.

Visualization is also used for getting a new perspective on scientific data. Alicia Sampson (2012) and Rebecca Eells (2012) worked with Kate Susman and Jenny Magnes to build visual models of worm behavior; Joe Tanski and Bona Ko (2010) used x-ray fluorescence spectroscopy to analyze the elements of art objects.

Social Networking
While these projects used technology to bring  students closer to their learning materials, others used technology to bring students closer to other people. Kelsey Forrest (2011) and others in Saúl Mercado’s class created a social networking site to benefit the Vassar community, while Leslie Williams and Adalake Barnwell created  a site to facilitate communication between local high schools students and the Vassar student mentors. Students in the Bioinformatics program created their own support group for fellow students. Some people used technology to  collaborate on their work: students in Leonard Nevarez’ class used a wiki for collaborative writing, while Tracey Holland used a wiki  to co-write with her own collaborators; Natalie Friedman’s class did their writing assignments on a shared blog site. Zeynep Gokcen Kaya, an exchange student from Turkey, presented her research on social interaction in virtual worlds.

Hybrids
Interestingly, two exhibits showed uses of technology that enhanced both visualization and social interaction: students in Jeremy Davis’ class used Skype to interview authors whose articles they were studying, while students in Hiromi Dollase’s class used videoconferencing to speak with students in Japan.

More information, along with photos and reproductions of each presenter’s poster can be found at <http://pages.vassar.edu/facultyforum>.Watch for the announcement of next spring’s event— you won’t want to miss it.

Welcome

by Steve Taylor

Welcome to Techademia, a site where the Academic Computing Consultants at Vassar write about technology and teaching.

This blog will be about our teaching and your teaching. We envision this site as a place where we hope to do a little teaching, about things that may be too new or obscure to have caught your notice. At the same time, these writings will  focus on teaching at the college level, while highlighting ways in which technology can enhance— or even revolutionize— that teaching.

Every faculty member that I’ve met at Vassar is wholly committed to his or her teaching. Many tell me that they’re really interested in one technology or another that might help their students to understand their course materials better. But they’re also really, really busy and can rarely find the time to take workshops or tinker around with new devices or programs.

We hope that his blog will provide a way for you to fit a little bit of this learning into your busy schedule. We aim to generate new postings each week, on various topics related to teaching with technology. Those topics will range from descriptions of very specific gadgets to discussions of pedagogical approaches. Some will be specific to Vassar, while others will be more generic.

The primary contributors will be the four members of Vassar’s Academic Computing Services (ACS) group. (If you’d like to know more about us, see the authors’ profiles, in the sidebar.) We may have occasional guest contributors as well, and we invite anyone in the Vassar community to comment on what they read.

Looking forward to some interesting discussions,

Steve
