Project Description:

ISIS students explored handheld devices for collecting data to create annotated maps. Students investigated GPS-enabled camera technologies and tracking software to determine the best tools and practices to create maps for a remote community. They created a toolkit, with a variety of devices and documentation, and an associated website, ISISmapping.  This toolkit will be used in DukeEngage project in Muhuru Bay, Kenya in the summer of 2009. 

The ultimate goal of this project is to create information-rich maps to be used in school and community center planning, fund raising, outreach, and education, in collaborate with DukeEngage, WISER, and members of the local Kenyan community.

Victoria Szabo and Sherryl Broverman will present this project at the 2009 Educause conference.

Julie and Vicki have published a research report on using audio feedback for peer review on student writing.  They used iPods distributed as part of the Duke Digital Initiative, to test if audio feedback is an effective way for students to offer high-quality comments to each other on their writing.   Their report “Can you hear us now?: A comparison of peer review quality when students give audio versus written feedback” (pdf) is published in the annual 2008 edition of The WAC Journal, a national peer-reviewed journal on writing across the curriculum.

Julie and Vicki noticed that when they gave students feedback on their writing, audio feedback was more time-efficient and seemed to be of higher quality than written comments.  They designed a study to find out if students would experience the same efficiency and effectiveness using audio feedback for peer review.  Students in their classes gave and received peer reviews using both audio and written comments.  Students were surveyed about their preferences and perceptions at the end of the semester.  In addition, Julie and Vicki assessed the quality of the peer reviews using defined criteria and two raters for each review.

They found that audio peer reviews contained more specific and higher order comments than written peer reviews.  They conclude that audio feedback significantly improves the quality of peer reviews.  The paper finishes with concrete suggestions based on their results and experiences with students for effectively using audio feedback in the classroom.

This paper is a great example of the Scholarship of Teaching and Learning; Vicki and Julie have carefully researched “what works” in teaching using audio peer reviews, and offered suggestions for others based on their results.

Project Background

In Spring 2008, Lucy Haagen, Visiting Lecturer in the Program in Education, used mobile phones to develop learning communities connecting Duke students with Durham high school students and mobile-learning resources. Haagen and the students used mobile phones both as traditional devices (i.e., as phones) and as capturing (for example, to record audio essays) and advanced communication (podcast broadcasting) devices. Based on the initial success of this program, CIT provided resources for Haagen to use mobile phones to facilitate ESL service-learning activities with DukeEngage in Vietnam during Summer 2008. Using the multimedia capabilities of the phones, Duke students used mobile phones as communication, documentation and instructional tools to enhance their work as English teachers in two villages outside Hanoi.

About the technology

Haagen’s project used Nokia N 72 handsets. Many mobile phone brands can be purchases as ‘unlocked’ and/or ‘international’ – meaning they’re not tied to specific carrier, and can be used in foreign countries by purchasing a ‘pay as you go’ SIM card after arriving in the destination country. In contrast to the US, where calls and text messages are most often charged to both callers and receivers, receivers of calls and text messages are not charged in Vietnam and many other Asian countries. Increasingly, even affordable mobile phones are equipped with cameras (still and video), voice recorders and messaging systems that don’t require internet connectivity.

Teaching strategies

1- Mobile phones as portable documenting tools

Multimedia-capable phones often include cameras that can take photos or even capture video. Built-in microphones can capture and record audio as well. Depending on the type of phone, these files can be shared between phones or downloaded onto a computer later. Some phones even include software for editing audio and video within the device itself. For ESL activities, audio/video recording is especially helpful, as students can record themselves trying phrases, and immediately listen to and/or view the results. In Haagen’s proejct, for example, one student created an audio diary by recording messages to a close friend. Other students used the mobile phones’ cameras along with audio narration to document various aspects of the culture.

2- Mobile phones to create ad-hoc networks

Mobile phones that are enabled to send and receive text messages can be used to communicate between smaller groups to arrange meetings, or even accept answers to short quiz questions. The cost of text messaging (SMS) in many foreign countries is far less than the cost of messaging in the US. Faculty Director on the Vietnam project, Erik Harms, used text messaging on a week-long field trip where students were trusted to explore on their own as long as they met up at appointed times and places. Program Assistant Duc Ho used text messaging to run an ad-hoc “admissions office” for one of the projects involving a 3-week English class for gifted high school students. Faced with more applicants than available spaces, Duc used text messaging to manage a waiting list and communicate with applicants as information became available.

3- Mobile phones as teaching devices

Throughout rural Vietnam, electricity is rationed. In summer, electricity rations (about 10 hours/day) are reserved for lighting and for running electrical fans at night – crucial to sleeping in a tropical climate without air conditioning. With power in such short supply, mobile phones took the place of laptops as presentation tools. English lessons were enhanced as small groups of students crowded around the instructor’s mobile phone, viewing pictures and listening to downloaded American songs and podcasts.

4- Mobile phones and teacher workshops

Haagen used her mobile phone to capture images, video and audio connected with English teaching in Hanoi and the two villages. With assistance from staff in Hanoi University’s new media lab (a gift from the New School (NY, NY), she used Apple i-DVD to create interactive DVDs. These DVDs were then used in a series of teacher workshops funded by the US Embassy in Hanoi.

Project description

This project will provide geographically dispersed online Duke nursing informatics graduate students with collaborative tools that will help them acquire, critique, summarize, and disseminate available HIT studies and evidence reports. Linda Goodwin will utilize informatics experts, mobile technologies, and remote (virtual) teamwork that enable both synchronous and asynchronous collaboration to compile HIT evaluation resources, critique them for level of evidence, and make them available to a world-wide audience. The project will be focused on immersing students, both Doctor of Nursing Practice (DNP) Program and Master of Science in Nursing (MSN) in real-world informatics issues and projects in health care.

Linda Goodwin and her students will experiment with different types of mobile tools and web-based citation tools, explore whether mobile technologies that permit student access to synchronous teamwork tools from anywhere they can gain wireless Internet access will improve both the process and the products of remote online teamwork.

Project Description

For Brenda Neece’s course on Musicology, a requirement of all incoming PhD candidates in the Music Department, Neece and her students experimented with the use of small form factor Ultra Mobile PCs (UMPCs) for field research. Neece, during her own research, used a handheld Psion in her work to take notes, dictation, keep track of sources and even make sketches as she travelled in many locations researching musical instruments. With this project, Neece introduced the students to new methods of integrating technology with field research.

The UMPC is a new form factor computer – essentially a small tablet PC – giving the students access to a full Windows Vista computer in a small package. The project allowed the CIT to gain an understanding of ways that students and faculty might use this novel new portable computer.

The CIT loaned Neece and her two students Sony UMPCs during the Fall semester. The UMPCs have a stylus and could be used much like a tablet to create quick sketches and music notation. The computer includes a built-in webcam and digital still/video camera, as well as wireless capabilities, built-in microphone and other features. The computers were pre-loaded with productivity software, such as MS Office, and Endnote for creating and using citations. The Music Department provided licenses for the music notation software Sibelius for use on the computers during the project.

Neece and her students used the UMPC’s for common tasks, such as web browsing and editing of Word documents, but focused primarily on using the devices for research.  They used library electronic resources using WiFi access, made notes using the writing input-based Windows Journal, created and edited short musical examples with the stylus in Sibelius, and used the built-in camera to take quick images of sheet music or instruments for reference.

Despite some technical problems due to the emerging nature of the UMPC platform, the reaction was positive.  “It is fantastic to have the power of a full computer in one’s pocket,” Neece said at the end of the project.  “This is exactly what I would have loved to have had when I did all of my fieldwork and library research for my doctorate instead of my little Psion.”

Project Description

“How do they connect? The past and the present?”

CIT provided Trudi Abel with funding and student support to create digital versions of historic maps of Durham using Google Earth. Using high quality digital copies of maps from the late 1800’s, Abel worked with CIT staff to figure out the best methods for converting, importing and placing images as overlays into Google Earth. The “georectification” of these maps presented several obstacles, requiring the team to consult with local Durham mapping and historical experts to complete the placement and positioning of these maps.

Several of the resulting digital maps have recently been added to Abel’s ongoing project – the Digital Durham website. Google Earth files can be downloaded and opened on users’ computers for exploration. Visitors to the site can also access several high resolution screen captures of the map overlays without the need to open or use Google Earth. The resulting maps can also be used in Abel’s work with Duke and local high school students – providing a basis for student research projects. Audio pieces created on iPods, geotagged photography and even short video clips can be linked directly to their historical and/or present-day locations.

“I think these maps will help users visualize an industrializing city and gain a better understanding of the process of urbanization in this New South community.”

This project created video series that demonstrate a specific adult physical examination taught in N332 Physical Assessment. The various formats of the videos were integrated to online courses posted in Blackboard, to self-paced web tutorials for online learning and to video iPods for mobile learning.

This demo session of the physical examination was taught each year to about 150-200 students in N332 Physical Assessment and Diagnostic Reasoning at Duke University School of Nursing. Faculty, actors, models who were involved in this demo had to repeat the same live demo to show many different sections of students before doing a laboratory practice.

This shift to ‘in house material’ videos and the subsequent movement of the clips to iPOD has changed instructors’ teaching in a major way. Because instructors not longer have to use live demo or non Duke specific video material the content drift for the course is much reduced. It has also very significantly affected the teaching style of at least 7 faculty and their respective courses. In addition, after instructors were able to fully utilize the videos this semester, the students have been so enthusiastic that they are moving ahead with this resource and influencing and enhancing their applications.

“The huge student enthusiasm for this product has convinced me that convenience and portability is very valuable to our students…likely to others…The university could do more to support these initiatives. They are time and resource intensive to start but the payoff is very good.” Dr. Susan Denman, the project primary investigator said when she evaluated this project.

Project description

In this advanced Hindi language course, Professor Satendra Khanna includes a wide variety of film and literature examples to increase student engagement with authentic language and culture. With the addition of iPods to the course, students in the course expanded their contact with authentic language even further by using their iPods to record weekly samples of actual Hindi in use at various South Asian diaspora sites in the Triangle. The language samples were analyzed in class to allow the incorporation of important locutions and vocabulary in student coursework. The introduction of iPod assignments allowed students to encounter the real language in real use, which required them to adapt to this Hindi-using environment rather than using language that is pre-filtered and simplified. Such exposure to Hindi in current use in the diaspora has dynamic consequences for Hindi instruction in the classroom.
