Mobile Princeton

For reunions last year, OIT created a special web site tailored for the small mobile devices that are now proliferating in the marketplace, cell phones with web browsers, iPhones, Blackberries, and the like. The experiment proved to be quite successful. To accelerate the development of such services, OIT signed an agreement in December that will give the University access to Blackboard Mobile, an environment that will permit users to access public information about the University in a format especially suited to such mobile platforms.

The result will soon be a Princeton-specific application, m.Princeton, for leading brands of smart phones.

Mobile Central was founded by a group of Stanford students who developed the core products offered by Mobile Central by rising to the challenge of a course assignment in a Stanford computer science class - the task: to deliver real mobile solutions for the Stanford campus community.

iStanford now permits users to search the campus directory and campus map, view athletics and course information, and a variety of other campus services. The students later formed the company TerriblyClever Design in 2007, and developed several more mobile suites for other colleges and universities.

During the past year, several universities, notably Stanford, Duke, and MIT, have used these same services to permit mobile users to access campus maps, directories of people and places, bus schedules and campus tours, event calendars, announcements and news, as well as images and videos.

Princeton is now building a full suite of such mobile applications for the benefit of the entire campus, as well as visitors, parents, and prospective students. OIT has assembled a team with representatives from several departments to complete the first phase of the work in time for reunions this coming May. The first phase will include a campus map, a campus directory, athletics schedules, course information, news, and the public events calendar.

During the first phase, Princeton will also assemble support for Reunions, from events and campus maps through directories and local restaurant menus.

The second phase will be ready in time for the fall. It will deliver real time shuttle information, access to the library catalog, an image gallery, additional video content, building maps (library floor plans, for example), as well as an online Orange Key tour.. Additional changes will be made as needed and will be delivered as updates to the existing application.

RyanIrwin.jpgAt the April 28 Lunch ‘n Learn seminar, Janet Temos ‘82 *01 and Ryan Irwin ‘10 of Blackboard Mobile Central discussed the details about the coming Princeton mobile apps. They noted that the apps will be delivered in formats that support the Blackberry Storm, Curve, and Bold, the iPhone, the iPod touch, and eventually the iPad. The apps will also work on any smart phone that can support a web browser. The application will be free, but users will need to download the application that suits their brand of phone.

The Apple applications will be available for download via iTunes. Blackberry applications will be available from the Blackberry app store. Blackboard Mobile Central and Princeton will host the web-based version.

Student with a Kindle

In the Fall term of 2009, Princeton conducted a pilot sponsored by the High Meadows Foundation, the University Library, and the Office of Information Technology, to assess the use of e-readers in the classroom. The reader used was the Amazon Kindle DX, a lightweight, portable e-reader with the capacity to hold approximately 3500 books, in three University courses.

The project aimed to explore the use of the e-readers in classes for which e-reserves were the primary readings. The printing of e-reserve readings at Princeton accounts for a large portion of printing in public clusters (total of 10 million sheets of paper last year). The e-reader pilot sought to target e-reserve readings and present them on an e-reader to see if printing could be reduced.

The pilot participants consisted of three faculty members, 51 students, and several administrators in the Library and the Office of Information Technology.

The three courses in the pilot involved considerable eReserve reading, all had some content in the Kindle store, and they had to be of a size that would permit the involvement of three courses. The courses in the pilot were Civil Society and Public Policy (Professor Stanley Katz, an undergraduate seminar), U.S. Policy in the Middle East (Ambassador Daniel Kurtzer, a graduate seminar), and Religion and Magic in Ancient Rome (Professor Harriet Flower, a graduate seminar).

Devices were given to students in September. The pilot was voluntary with opt-out possibilities at any time. One student opted out at the start of the pilot. No student opted out after the pilot began. Students were asked to do the bulk of the course reading on the Kindle. 95% of the students reported that they had not previously used an eReader.

Participants were asked to do pilot course readings on the e-reader without printing as much as they felt it was possible. The pilot concluded with a survey and some final focus groups in February 2010.

The survey results are available at at the e-reader project web site and in the presentation slides.

The goals of the pilot were to reduce the desire to print, to explore the unique strengths of eReaders, all while being careful not to affect adversely the classroom experience.

At the April 14 Lunch ‘n Learn seminar, Janet Temos, Director of OIT’s Educational Technologies Center, Stan Katz and Dan Kurtzer two of the faculty involved in the pilot, and Trevor Dawes, Circulation Director at the University Library reviewed the findings of the Princeton e-reader pilot and shared their experiences.

Temos reported that the pilot did indeed reduce students’ desire to print.

Students judged the screen size, image resolution, device weight and storage capacity to be excellent. Highlighting, annotating, navigating within and between books, and the dictionary features achieved much less positive evaluations. Overall, Temos reported, the students thought that the devices had promise, the reason they said at the end that none opted out.

Kurtzer noted that, in his graduate seminar, all of the students were expected to read the course material before coming to class. And so, while they may have experienced some challenges with navigation, those did not occur in class. He reported that all of the students liked the fact that they could carry all of their reading around all of the time.

Many of Kurtzer’s students have recently downloaded material from current classes to maintain the experience. Main criticisms included highlighting, keeping track of bookmark references, and moving between and among passages from different books.

One problem that the pilot addressed was the difficulty of working with pdf documents because you can’t enlarge the type size. The only surprise in the data, reported Kurtzer, was that the pilot appears only to cut down 50% of the students’ printing.

Use of the Library’s eReserve system has grown exponentially, Dawes commented. The pilot provided a good opportunity to test the use of the eReserves system on an eReader platform. For this project, the processing was different in that it was required to scan the pages individually, trimmed, and processed further by OIT staff. Early on, we discovered that the Kindle could not read pdf documents in their native format. The amount of staff time involved was large and, he concluded, would not be sustainable for the device. We will continue to monitor progress to see if new devices will be able to accommodate pdf’s more efficiently.

Professor Katz’s course involved 23 books. He emphasized that the device is superbly ideal to accompany travel, and he and students agree wholeheartedly with that assessment. That said, it was wholly inappropriate for the close textual work involved in the course.

Classroom discussion required that all students be looking at the same passages, and they were expected to annotate those passages. Annotations collapse into footnotes, the keyboard is tough to use, and the Kindle had built-in limits on the amount of text that could be highlighted and annotated. The tedious nature of finding passages caused consistent classroom confusion. All that said, he is off to San Francisco for a dissertation review. “I will load it into the Kindle, said Katz, “and love it once again.”

Molecule visualization

Princeton University has created a cyberinfrastructure, says Curt Hillegas, the Director of Princeton's TIGRESS High Performance Computing and Visualization Center, itself a collaboration between the Princeton Institute for Computational Science and Engineering (PICSciE). Developed within the past decade, this cyberinfrastructure consists of computational systems, data and information management, advanced instruments, visualization environments, and people, all linked together by software and advanced networks to improve scholarly productivity and enable knowledge breakthroughs and discoveries not otherwise possible.

At the April 8 Lunch 'n Learn seminar, Hillegas noted that the University's research computing activity has grown to keep pace with and to provide leadership for this international trend. Tigress maintains a vast hardware and storage infrastructure. And staff provide support for programming and for the new visualization facilities within the Lewis Science library.

The effort, of course, also involves faculty across many disciplines and departments. This session highlighted the work of two University faculty: Professor Annabella Selloni from Chemistry and Professor Clarence Rowley from Mechanical and Aerospace Engineering. The session demonstrated how computational science and engineering is enabling and accelerating scientific discovery.

Annabella Selloni’s research activity is aimed at obtaining a microscopic understanding of the property of materials with specific emphasis on surface and interface phenomena. At the Lunch ‘n Learn seminar, she discussed the quest to discover an efficient and perhaps less expensive alternative to platinum as a catalyst for the production of hydrogen. Princeton’s high performance computing systems have permitted her to model and to manipulate functionalized electrodes. At the seminar, she played simulations that illustrate how small surface changes can have a significant effect in the production of hydrogen.

Professor Clarence Rowley is modeling flows past a cavity, as would occur with a sun roof or an aircraft wheel well or weapons bay. Although his efforts have employed the processing power of a supercomputer, his aim has been to achieve workable results and a control design with a much more limited number of equations. Full systems require as many as 2,000,000 equations. Rowley now has control designs based upon just two equations. With such active control, it may be possible, for example, to mimic the fluid dynamics of insects and small birds and to design a controller to stabilize the leading edge of aircraft wings.
