Overview of the Handheld Devices for Ubiquitous Learning Project

The Handheld Devices for Ubiquitous Learning (HDUL) project is an exploratory study that seeks to determine how wireless handheld devices (WHDs) can enhance learning and teaching in university settings. Our motives for investing in HDUL are based on the devices people own and carry, society’s cultural and technical movement towards ubiquitous computing, WHDs’ potential for harnessing situated and distributed cognition capabilities, and emerging media-driven learning styles. During the 2003–2004 and 2004–2005 academic years, HDUL integrated WHDs into eight diverse courses at both the Harvard Graduate School of Education (HGSE) and the Harvard Extension School (HES) as summarized in Table 1 below.

The Promise of Ubiquitous Computing

In the late 1980’s, Mark Weiser began writing and discussing the potentials of ubiquitous computing –– computing in which computers are no longer seen and resides in the periphery of our daily lives (Weiser, 1991). Since then, ubiquitous computing (UbiComp) has become an area of study in computer science and electrical engineering (see for example Abowd & Mynatt, 2000). Furthermore, UbiComp is changing the way that people see and use computers.

The computer-human interaction trajectory, according to Weiser (1996), can be thought of in three waves. The first computing wave tied many people to a single mainframe computer. Users of such computers had highly specialized skills that were not representative of average citizens. The second wave connected individuals to desktop and laptop computers, thus providing a one-to-one computer-to-human ratio. The third wave is the era of ubiquitous computing, whereby many computers interact with one person, or many computers interact with many people. Using the foundation of UbiComp, Chris Dede suggested the potential of UbiComp in education through the characters of Alec and Arielle as they explore a museum with their handheld devices (Dede, 2002).

Vignette 2 Alec and Arielle strolled through Harvard Yard on their way to the museum, to collect data for their class assignment. Each carried a handheld device (HD) that softly pulsed every time they walked past a building in the Yard. The vibration signaled that the building would share information about its architecture, history, purpose, and inhabitants, using interactive wireless data transfer. Sometimes Alec would stop and use his HD to ask questions about an interesting looking location. Today, he was in a hurry and ignored the pulses. Inside the museum, Alec and Arielle split up to work on their individual assignments. When Alec typed his research topic into the museum computer, it loaded a building map into his HD, with flashing icons showing exhibits on that subject. At each exhibit, Alec could capture a digital image on his HD, download data about the artifacts and links to related websites, and access alternative interpretations about the exhibit. His HD automatically supplied information about Alec’s age and background to ensure that the material he received was appropriate in native language, reading level, and learning style. While the museum-supplied information was interesting, Alec always enjoyed the comments posted about each exhibit by other kids. Sometimes, he added a few remarks of his own to the ongoing discussion. Seeing a cool artifact related to Arielle’s topic, Alec paused to link to her HD, sending a digital image of the exhibit and information on its location. Alec’s favorite exhibits were those augmented by virtual environments. For example, at a panorama showing the bones found at a tar pit, Alec’s HD depicted a virtual reconstruction of the dinosaurs that were trapped at that prehistoric location. In the virtual environment, he could assume the perspective of each species and walk or fly or swim through its typical habitat. Other types of exhibit-linked virtual environments enabled “time travel” to show how a particular spot on the earth’s surface had changed over the eons. For each epoch, Alec used virtual probes on his HD to collect data about temperature, air pressure, elevation, and pollutants. Walking back from the museum, Arielle and Alec shared what they had found. Both wondered what learning was like before augmented reality and ubiquitous computing, when objects and locations were mute and inert. How lifeless the world must have been!

In addition, Dave Keefe, Phoebe Farag and Andy Zucker's (2003) "Ubiquitious Computing Project: A Brief History" summarizes the histories and findings of various initiatives and how they played out in educational settings.

Wireless Handheld Devices

While the literature on ubiquitous computing is purposely device non-specific, wireless handheld devices (WHDs) offer many of the features theorized by Weiser and discussed by Dede. As a broad class of devices, WHDs include but are not limited to cellphones, personal digital assistants, handheld gaming devices, and portable music players. Despite their dissimilarities, WHDs share five commonalities: 1) Connectability – they connect to the Internet wirelessly via wireless fidelity, or WiFi, 2) Wearability – they are wearable and therefore always at the fingertips of the user, 3) Instant Accessibility – they turn instantly on and off, 4) Flexibility – they can collect data by accommodating a wide variety of peripheral extensions, and 5) Economic Viability – they have much of the computing capability and expandable storage capacity of laptops at a fraction of the cost (Dieterle, 2004).

Exemplar Uses of Handheld Devices in Education

Overview

In "A Report Card on Handheld Computing," authors Jean Shields and Amy Poftak (2002) first provide a short history of handheld devices before examining their potentials for schools. By striking a balance between the strengths and limitations of handheld devices, Shields and Poftak portray handhelds objectively as they pertain to education. At the end of their article, they provide a variety of resources designed to help educators sort out different devices, find useful applications, and develop an implementation strategy.

Dr. Charles R.

Since then, he and his chemistry colleagues have constructed a 1-to-1 student to Pocket PC ratio for each semester’s 35 chemistry sections. | Link to General Chemistry Labs
