Bb Tip: Students share files within Blackboard

February 27th, 2009 by Haiyan Zhou

Peer collaborative learning enhances the value of student-to-student interaction and results in various advantageous learning outcomes.  Instructors can use the Blackboard’s built-in collaboration tools to allow students to access each others’ files within Blackboard for peer review and feedback.

Instructors can choose tools for students to share files in a number of ways:

  • through the Discussion Board,
  • via Group File Exchange,
  • using the Blackboard Blog and Wiki Tool.

See more from the Duke Knowledge Base.

To explore and discover additional Blackboard features, see the Blackboard support website. If you would like more extensive help for Blackboard, request an office visit and we will come to you.

Open source tools for teaching, research and learning

February 25th, 2009 by Lynne O'Brien

I’ve just returned from The Andrew W. Mellon Foundation’s Research in Information Technology retreat at which project leaders are sharing information about open source projects in higher education and in arts groups and museums (http://rit.mellon.org/2009-rit-sc-program-retreat).  Open source tools (i.e., no purchase or license fees) may be of increasing interest in the current economic environment. I wonder whether these specific tools might be of interest to faculty and students at Duke. Several products might be good extensions to the Duke Digital Initiative because of their emphasis on producing, managing and analyzing multimedia resources. Other projects or tools could be extensions of the library’s work, as the library becomes not only a source of content, but a source of consultation on working with that content in new ways to further research.

Sophie – http://www.sophieproject.org/

Sophie is a multimedia authoring tool: “software for writing and reading rich media documents in a networked environment.” People who have used it, including high school students, describe Sophie as very easy to use. Sophie is currently being rewritten in Java, and with emphasis on collaboration tools. The project’s website provides illustrations of how Sophie is being used. For example, Sol Gaitan of the Dalton School in New York developed a multimedia book for her AP Spanish students so that they could explore the direct influence of particular flamenco music styles on Lorca’s poetry. Gaitan presents both the songs and the poems they inspired, and annotates the poems from pages 11 to 43; with the students expected to follow her lead by annotating the poems in the remainder of the book. Take a look: http://www.sophieproject.org/demobooks

VUE – http://vue.tufts.edu/

VUE provides a flexible visual environment for structuring, presenting, and sharing digital information. VUE lets you look for relationships across images, define relationships, compare images, etc. As such, it is a research tool as well as a presentation tool. The VUE website has a short video (http://vue.tufts.edu/screencast/QT_hiRes.cfm) that gives an overview of its functions and how it can be used.

Zotero – http://www.zotero.org/

Zotera is free, easy-to-use Firefox extensions to help you collect, manage, and cite your research sources. Some of us are familiar with Zotero as a citation management tool. The developers as well as other project leaders at the RIT meeting see Zotero as having additional functionality through its connections with other tools. For example, the planned redesign of the Sakai course management system may have ways for instructors to upload lists of their publications, and then, via Zotero, find other scholars with whom they might want to connect.

eComma – http://ecomma.cwrl.utexas.edu/e392k/

The eCommentary Machine web application (“eComma”) will enable groups of students, scholars, or general readers to build collaborative commentaries on a text and to search, display, and share those commentaries online.

Sakai 3- http://confluence.sakaiproject.org/confluence/display/DOC/Sakai+3.0

A completely re-architected version of Sakai is planned for summer of 2010. This version will move away from the cookie-cutter view of course sites and instead connect with 3rd party tools (such as WordPress) and utilize gadgets and widgets that allow a site to look more like a Google personal homepage. The idea is to reflect the look and feel of tools that are already popular. You can see a demo of creating a Sakai 3 site here: http://www.sakaiproject.org/portal/site/sakai-home/page/89473b2c-31dd-4261-9823-c31a79e55532

Participants at the RIT meeting also talked about people “curating their own arts experiences,” a reflection of growing expectation for web 2.0 type functionality. As an example, someone mentioned Sonic Living, (http://sonicliving.com/) which is not an open source product, but is a relevant example. It scans your hard drive, looks at your iTunes and then suggests live music in your area that matches the interests it found. It also lets you know what concerts your friends are attending. The arts and museum community is looking for ways to get information about their organizations, performances, etc. into the workflows people already have rather than expecting them to come to a website to find information about upcoming events.

Educause Learning Initiative Conference 2009

February 24th, 2009 by Shawn Miller

Andrea Novicki and I (Shawn Miller)  attended the Educause Learning Initiative’s 2009 Conference January 20-22 in Orlando.

Link to Educause conference archive (videos, ppts, etc): http://connect.educause.edu/term_view/eliannual09

The conference: the meta-experience

ANDREA: ELI is attended by people who are excited about using technology in teaching. The attendees (faculty, learning center folks, instructional technologists) may also be excited about technology in general, but the focus is on the possibilities that technology provides for education.  The organizers and attendees are the sort of people who are willing to try things to find out what works. Therefore, there are many experiments at this conference: types of sessions, varieties of activities, and how people learn at the conference (which is the most interesting to me). It’s like being able to see into the future, or, even better, getting to play in the future.   (more…)

SIMILE Timeline: If the President can use it, you can too

February 19th, 2009 by Shawn Miller

If you’ve looked at the new Recovery.gov site recently, you’ve probably noticed an interesting interactive element at the bottom of the main page.

This timeline is a good, simple example of the SIMILE Timeline tool created by MIT Libraries, and MIT CSAIL.

SIMILE Timeline tool general info:

Original project homepage: http://simile.mit.edu/timeline/
New, Google-hosted homepage: http://code.google.com/p/simile-widgets/
Getting Started guide: http://simile.mit.edu/wiki/Timeline#Getting_Started
See examples here: http://simile.mit.edu/wiki/Category:Example_timeline

Though creating the timeline does require someone to actually edit code, the code for the timeline is not much more complex or daunting than the average HTML website. Here’s an example of a process that might be employed as an assignment wherein students would collaboratively build a timeline.

I. SIMILE uses two files to work properly. First, there’s an .html file (I’m calling this file ‘timeline.html’) that presents the application and includes several tweakable parameters. The .xml file (which I’m calling ‘events.xml’) is the code representing the times, dates, headings, description and image links for the specific event.

II. Download and/or reuse these files:

1. events.xml – this file lists all the events. Copy/paste more events after </event> tag for previous events. Events don’t need to appear in any particular order.

2. timeline.html – This is the file that includes the modifiable code for the SIMILE timeline. This is also the file that you would link to for viewing the timeline.

3. Use Lifehacker’s XML generator script to quickly create xml form data
http://www.lifehacker.com/assets/resources/2006/10/eventmaker.html
OR download/save eventmaker.html and upload it to your own webspace.

III. Possible student process

1. Students collect different event detail, images, etc. Perhaps groups of students work together collecting events based on particular themes or chunks of time, etc.

2. Creating a ‘wiki’ tool in the course Blackboard pages for each group may help them collaboratively work out the event details and images before they run them through the xml generator.

3. Once the final details are set (image URLs are prepared, dates verified, titles and descriptions set), the student(s) can go to the eventmaker.html page and generate the xml code snippet for their event.

4. Students can post this code on another Bb wiki representing the entire xml code for the timeline. The faculty member, a TA, and/or a student would then grab this code either periodically, or toward the end of the semester, and upload it to the Duke WebFiles space as the new events.xml file.

Still too complex? Well, Google has you covered. The timeline can now be created as a ‘widget’ when using Google Spreadsheets.

A webpage written by David Huynh explains the whole process. Suffice it to say that this process only requires a class to create and share a single Google Spreadsheet file, and then simply edit the content cells to work. Enjoy.

Display student work in Perkins library

February 18th, 2009 by Andrea Novicki

Have your students produced work you’d like to show the world? Display it on the Student Wall in Perkins Library. The Student Wall, on the first floor of Perkins Library, is available for exhibits of work created by students for classes, research or internships and for displays by student organizations related to their projects. Displays will highlight civic engagement, social issues, and experiences closely related to formal coursework.

Students are responsible for producing professional looking materials in whatever size and format that is appropriate to their exhibit as long as it fits on this wall. The materials must be suitable for hanging in this space either backed with a solid material (such as foam core) or placed in frames. Students will be responsible for mounting and taking down the exhibits with help from the library exhibits coordinator. Material will be displayed for a minimum of 3 weeks.

For more information or to schedule a display, contact the exhibits coordinator, Meg Brown.

Avoiding “Death by PowerPoint”

February 17th, 2009 by Randy Riddle

Recently, the CIT offered “Death by PowerPoint”, one of our regular workshops that look at using technology in your teaching.  We offer ideas for improving student learning and engagement or managing your courses.

PowerPoint (and other presentation tools) are ubiquitous in the classroom and both students and faculty have a kind of “love/hate” relationship with them.  While you can present material concisely, integrate images or other media and easily distribute presentation material to students for reference, the software can make lectures inflexible or take away from the interactivity of an engaging classroom session.

Our workshop focused on five principles of effective multimedia for learning, based on Dr. Richard Mayer’s research.

Signaling
Mayer found that students learn better when materials are organized to highlight essential ideas.   On a slide, you might use the heading of the slide to state the main point or produce a series of slides that take students through a clear, outlined process.

Multimedia
People learn better from words and pictures than from words alone.  Use images or diagrams to convey information.

Modality
People learn better from graphics with spoken text rather than from graphics and on-screen text.  Text on the screen is actually distracting.  Text-heavy information should be spoken and/or presented in handouts for later reference and reinforcement of your ideas.

Segmentation
Too much information is often a problem with presentations.  Students learn better when information is presented smaller segments.  Each point on should have it’s own slide.

Coherence
Students learn best when extraneous material is excluded.  It may be tempting to spice up a presentation with “bells and whistles”, but these actually detract from learning. Only include materials that support the message.

We also discussed ways to make lectures more interactive and engaging.  Students stay more alert and focused if you take a break after every few slides and engage students.  Small group activities can be quick and offer feedback on student learning.  For example, students can be broken into pairs to discuss a brief question and then report, students can  “shout out” ideas that you would write on the board or type on a blank PowerPoint slide.  Or, in larger class settings, you might use a Personal Response System or “clickers” to have students vote or answer questions about the material.

Finally, we discussed good visual design.  Keep presentations simple works best – background images and different colors take the focus away from your content.  And, take a break.  Project a blank screen during the presentation to bring the student’s focus back to you for important points or for discussion.

Students produce videos at Duke’s Marine Laboratory

February 16th, 2009 by Andrea Novicki

Students in Marine Invertebrate Zoology have created short videos about published research articles. The videos can be seen in on the course YouTube Channel; catch some of the students’ enthusiasm for invertebrates while they explain published research in marine invertebrate zoology. This course is taught at the Duke University Marine Laboratory by Cindy Van Dover; Andrew Thaler is the teaching assistant.

Students share top billing with invertebrates like squid and dwarf worms, and provide a window into life at the marine station. Here’s the video about my favorite animal.

Catalogue of Digitized Medieval Manuscripts and social bookmarking

February 11th, 2009 by Randy Riddle

The Chronicle of Higher Ed has a blog post highlighting the Catalogue of Digitized Medieval Manuscripts, an online database that links to digitized materials in various collections.

While many libraries and institutions are digitizing parts of their collections, it’s not always easy to find material in a specific subject area.  These “aggregator” sites may become more common as scholars with common interests share links to materials.

Students in a class could put together something like this as part of activities centering around research in a course, using social bookmarking tools like Google Reader or delicious.

Getting Personal (part 2): Michael Wesch and the ‘Just in Time’ personal web

February 10th, 2009 by Shawn Miller

NOTE: This post is part 2 in a series addressing concepts found in the 2009 Horizon Report. Part 1 can be found here.

Michael Wesch, a professor of Cultural Anthropology at Kansas State University gained some internet fame a few years back by publishing a video on YouTube called “Web2.0…The Machine is Us/ing Us.” Since then, Wesch has been adding an impressive set of Web2.0 tools to his courses, using them both for producing and sharing content with his students. In other words, Wesch uses tools developed for the social and/or personal (blogs, YouTube, etc) as instructional technologies.

The screenshot below shows Wesch’s Netvibes page for his course “Mediated Cultures: Digital Ethnography.” Netvibes, much like iGoogle or Pageflakes, is a service that allows users to bring together various elements of their online existence onto one page. Some would also call this an ‘aggregator’ or a ‘portal.’ In Wesch’s Netvibes page, he’s created a virtual dashboard that provides the following info on one page:

  • recent updates to his students blogs (1)
  • recent updates to the course’s wiki page (2) created using WetPaint
  • a Google Calendar (3) shows the class and assignment schedule
  • all recently bookmarked links to websites and/or articles by the course (4) using a tool called Diigo

Looking at Wesch’s site might seem overwhelming at first – but it works on some simple concepts including a variation of a teaching concept called Just in Time Teaching (JiTT). “Just-in-Time Teaching” asks the question: “How can the web, a new tool, help students take more responsibility for their learning under mindful expert supervision?” (Novak & Middendorf, 2004).

Here’s how the basic idea could work using a Blackboard assignment. A faculty member notices students haven’t been keeping up with the reading, and on top of that, notices that the students who have been reading aren’t comprehending certain key points. A JiTT solution may be to create a two or three question assignment in Blackboard to be completed the night before class. The questions aren’t difficult, and don’t require more than 200 words each to answer. Before class the following day, the faculty member quickly glances over the answers. Now our faculty member has a) a better idea of how many students have actually done the reading, and more importantly, b) a much better idea about what the students are and are not comprehending, making it much easier to focus lecture and class time on the problem areas, or avoid re-teaching concepts that the students already appear to have mastered.

In many ways, Wesch is applying these same concepts to his course – only technology has advanced to the point where its not even necessary to wait until students all submit answers to an assignment. Look at the screenshot of Wesch’s Netvibes page again. With one glance, Wesch knows that his students have been uploading their assignments to their blogs (’Trailer 2′), knows that some of his students were having some difficulty with audio (see the comments section), has an idea of how many students have accessed the wiki and are working in groups, and can also get a general idea of how much research his students are doing, and what they’re finding interesting (via the Diigo ‘tagged links’ box #4).

Now, let’s take this one step further. At a presentation Wesch gave at ELI 2009, Wesch mentioned that he was also interested in removing distractions from his course. A semester or two ago, he had been using Facebook in his course – but now finds Facebook to be a gateway for distraction. No problem – Wesch just changes the tools and moves on. This is a crucial point to consider, and something we (instructional technologists) deeply believe, but sometimes forget to make clear: it’s not about the tools, it’s about your content. Or, put even more plainly: it’s not the tools, it’s your class.

Course planning can be frustrating – especially given the broad range of technologies now available. Wesch’s successes demonstrate that we don’t have to always put technology first – and in fact, we shouldn’t. Consider what you want to do with your course, what you want your students to achieve, and then plan from there. Is there a new technology that you think might work? There’s a good chance that it’s simple enough to implement. The key here is to not get too attached or ‘hung up’ on a certain technology, but to instead be prepared for changes. If we understand that our content and the collaborative/community aspects of working with a group of students is what’s ultimately important, we can better adjust to use any combination of technologies we choose.

Visualizing Pharmacology

February 4th, 2009 by Andrea Novicki

Duke students Marcel Yang and David McMullen (pictured) produced a three dimensional visualization for teaching pharmacology as an independent study project with Rochelle Schwartz-Bloom and Rachael Brady.  They have tested the impact of their visualization on student learning in Duke’s Immersive Virtual Environment (DiVE) as well as on computer screens. They are currently preparing their visualization  to be entered in the NSF Science and Engineering Visualization Challenge.

This project is partially supported by a Center for Instructional Technology Visualization Grant.

See their presentation at the Visualization Forum.
