Closing the Digital Divide? the $100 PC and Other Projects for Developing Countries
Closing the Digital Divide? The $100 PC and Other Projects for Developing Countries Nina Malakooty Personal Computing Industry Center The Paul Merage School of Business, University of California, Irvine 3200 Berkeley Place North Irvine, California 92697-4650 949.824.6387 February, 2007 The Personal Computing Industry Center is supported by grants from the Alfred P. Sloan Foundation, the U.S. National Science Foundation, industry sponsors, and University of California, Irvine (California Institute of Information Technology and Telecommunications, The Paul Merage School of Business, and the Vice Chancellor for Research). Online at http://pcic.merage.uci.edu. 1 INTRODUCTION Bringing inexpensive computers to the developing world has been the focus of numerous government initiatives supported by technology proponents who feel that computers can bring social, economic, and educational benefits to countries where technology is considered a luxury. While private companies and governments have tried to deploy the necessary technology and support, myriad initiatives have ultimately failed or fallen short of their intended impacts. In most cases, the economic and infrastructure conditions necessary for success have been lacking. An ambitious project in the United States, nicknamed the “$100 PC Project,” now seeks to succeed with a plan for low-cost computing in the developing world. Nicholas Negroponte, co- founder of the MIT Media Lab, has formed a new organization called One Laptop Per Child (OLPC), with the intent to develop a $100 laptop for millions of children worldwide. With $20 million in start-up investment, agreements with major technology corporations and interest from at least seven countries worldwide, his goals have attracted interest, but challenges remain. -

One Laptop Per Child (OLPC) Is a Nonprofit Organization Founded in 2005 by Nicholas Negroponte, Also the Founder of MIT's Prestigious Media Lab
One Laptop Per Child (OLPC) is a nonprofit organization founded in 2005 by Nicholas Negroponte, also the founder of MIT's prestigious Media Lab. OLPC's goal is to “create educational opportunities for the world's poorest children by providing each child with a rugged, low-cost, low-power, connected laptop with content and software designed for collaborative, joyful, self- empowered learning” (Mission Statement, OLPC). However, the history of the program was fraught with challenges, setbacks, and limitations: after 2006, when the XO laptop was manufactured and deployed in least developed countries, a variety of criticism was leveled at the project, directed both at the hardware itself and the strategies of distributing laptops to children. This literature review is an analysis of the benefits and limitations of One Laptop Per Child project within the educational sector, particularly focused on deployments in the continent of Africa. A brief history of the OLPC project and the concept of the digital divide will be followed by an analysis of the project’s five core principles. I conclude that the project’s overarching goals severely limit the adaptability of its deployments to specific geographical and cultural contexts and reduce the educational benefit of the laptops, as shown by recent evidence from deployments in Ethiopia, Rwanda, and Tanzania. One Laptop per Child Long before conceptualizing the OLPC project, Negroponte (1995) set forth a philosophy which saw the digital revolution as being problematic, yet inevitable. According to him, technology and globalization will fundamentally change the role of the nation-state, making governments “both larger and smaller” (p. -
Meet the Eee PC
Chapter 1 Meet the Eee PC In This Chapter ▶ Not your average laptop ▶ Popular Eee PC misconceptions ▶ Reviewing Eee PC models ▶ Selecting an Eee PC ▶ Purchasing an Eee PC his chapter introduces you to the ASUS Eee PC. (Eee PC is pronounced Twith a single E, not multiple EEEs, as in “Eeek, a mouse!”) If you’re won- dering where all those Es came from, it’s from a marketing campaign that states the computer is “Easy to learn, easy to work, and easy to play.” In this chapter, I tell you what the Eee PC is — and just as important, what it isn’t. I then list available models, describe their specifications, and conclude by giving you tips on selecting and purchasing an Eee PC. Eee PC: Not Your Average Laptop The Eee PC (see Figure 1-1) has been called a mini-laptop, a subnotebook, a Mobile Internet Device (MID), and a netbook (a catchy marketing buzzword for small, Internet-centric laptops). Whatever you call it, the Eee PC is a shrunk- down, lightweightCOPYRIGHTED laptop that has these keyMATERIAL features: ✓ Small — At just a bit over two pounds and roughly the size of this book, the 7-inch and 8.9-inch screen models are designed to be go-anywhere, do-anything personal computers. To fit in such a small package, keys on the Eee PC are smaller than those found on a typical laptop keyboard — right around 83 percent of normal. After you get used to the small size it’s possible to touch type with some practice. -
Crucial Considerations in One-To-One Computing in Developing Countries

Various versions of one- to-one computing have recently been implemented around the developing world. Governments and educational organizations have often felt a pressure to acquire new technology as an effort to leapfrog development, but this has in most cases been done without any deeper analysis of the complete framework that successful one-to- one computing initiatives require. A number of One Laptop Per Child (OLPC) projects have subscribed to the view that one-to-one computing should not delve into non-technical areas like teacher training, curriculum development, or content development. We, however, consider the non-technical issues to be of great importance for the success of computer-enhanced learning in primary schools. This paper presents and analyzes nine crucial and often neglected considerations for successfully implementing one-to-one computing initiatives: a pedagogical framework, teacher training, a support model, content in local languages, adaptation to local conditions, parental agreement and support, monitoring and evaluation, administrative support, and sustainability. -

Una computadora personal esta orientado al uso individual y se diferencia de una computadora mainframe, donde las peticiones del usuario final son filtradas a través del personal de operación o un sistema de tiempo compartido, en el cual un procesador grande es compartido por muchos individuos. Después del desarrollo del microprocesador, las computadoras personales llegaron a ser más económicos y se popularizaron.

Fueron de interés principalmente para los aficionados y técnicos.

TECHNOLOGY AND COMMUNITY DEVELOPMENT BCD 216 LECTURE 12 DETERMINING A SUSTAINABLE APPROACH (CONT’D) 10) Health care According to the Global Health Council, rather than the use of professionally schooled doctors, the training of villagers to remedy most maladies in towns in the developing world is most appropriate. Trained villagers are able to eliminate 80% of the health problems. Small (low-cost) hospitals - based on the model of the Jamkhed hospital – can remedy another 15%, while only 5% will need to go to a larger (more expensive) hospital.Before being able to determine the cause of the disease or malady, accurate diagnosis is required. This may be done manually (through observation, inquiries) and by specialised tools.Herbalist medicines(e.g. tinctures, tisanes, decoctions) are appropriate medicines, as they can be freely made at home and are almost as effective as their chemical counterparts. A previous program that made use of herbal medicine was the Barefoot doctor program. A phase-change incubator, developed in the late 1990s, is a low cost way for health workers to incubate microbial samples.Birth control is also seen as an appropriate technology, especially now, because of increasing population numbers (overpopulating certain areas), increasing food prices and poverty. It has been proposed to a certain degree by PATH (program for appropriate technology in health).Jaipur leg was developed by Dr. P. K. Sethi and Masterji Ram Chander in 1968 as an inexpensive prosthetic leg for victims of landmine explosions.The Leveraged Freedom Chair is a low-cost wheelchair designed specifically for rough terrain,Natural cleaning products can be used for personal hygiene and cleaning of clothing and eating utensils; in order to decrease illnesses/maladies (as they eliminate a great amount of pathogens).
