Challenges and Impacts of One Laptop Per Child
The PRIDE Project Project Pacific Education Series, 2009 http://www.usp.ac.fj/index.php?id=publications CHALLENGES AND IMPACTS OF ONE LAPTOP PER CHILD AUTHORS • David Leeming, OLPC Coordinator, SPC http://wikieducator.org/User:Leeming • Ian Thomson, RICS and OLPC Project Manager, SPC [email protected] • Tony Forster , Games Programming Cluster of Schools, [email protected] INTRODUCTION This paper describes and advocates the One Laptop Per Child (OLPC) programme as a potentially transformational approach to much-needed education reform in the region. The main challenges for an OLPC programme are explained, based on experience from OLPC trials projects in several regional countries implemented by the Secretariat of the Pacific Community (SPC) in association with the OLPC Foundation. The paper also discusses the potential pedagogic impacts, and provides some promising early feedback from the trials projects. SUMMARY AND GOALS The regional priorities for education in the Pacific region are embodied jointly in strategies such as the Pacific Island Forum’s Forum Basic Education Plan, and nationally under the member states’ own reform programmes that are supported by various donors. These priorities include improving and transforming teacher education, curricula, and vocational education, with many voices (c.f. the University of the South Pacific’s PRIDE Project) calling for more Pacific cultural relevance and culturally appropriate pedagogy and content introduced into all of these areas, as well as a shift towards more progressive methods such as “active learning” and “learning by doing”. There are a lot of challenges within these areas. The OLPC or One Laptop Per Child is a charitable project which aims to place sub $100 laptops into the hands of third world children. -

One Laptop Per Child Birmingham: Case Study of a Radical Experiment IJLM
FORMULATIONS & FINDINGS One Laptop per Child Birmingham: Case Study of a Radical Experiment IJLM Mark Warschauer Abstract University of California, Irvine [email protected] The One Laptop per Child (OLPC) program has sought to transform education by developing Shelia R. Cotten University of Alabama, Birmingham and distributing to low-income children around [email protected] the world an inexpensive computer with an in- novative interface and applications. This article investigates the implementation of OLPC in Morgan G. Ames Stanford University Birmingham, Alabama, where some 15,000 of [email protected] the group’s XO laptops were distributed to all first- through fifth-grade public school students and their teachers. Surveys were collected from a representative sample of children before and af- Keywords ter they received their laptops, supplemented by One Laptop per Child observations and interviews in a Birmingham educational reform school. The use of the XOs by teachers and program evaluation schools, the ways social and technical infra- structure affected program implementation, and the types of XO use by students are examined. The disappointing results of the Birmingham program, which has been discontinued, are an- alyzed in relationship to OLPC’s technocentric approach, the organization’s principle of child ownership, and the design elements of the XO hardware and software.

TAXONOMY for MOBILE TERMINALS a Selective Classification Scheme
TAXONOMY FOR MOBILE TERMINALS A Selective Classification Scheme Gunther Schiefer and Michael Decker Institute of Applied Informatics and Formal Description Method, University Karlsruhe (TH), 76128 Karlsruhe, Germany Keywords: Simple Phone, Feature Phone, Smartphone, Handheld, Web-Tablet, Netbook, Mobile PC, Tablet-PC, classification, mobile Terminal. Abstract: There is a great number of different types of mobile computing devices like cellular phones, Handhelds and notebooks. However in literature so far there is no common accepted definition for these terminal types. Es- pecially the term “Smartphone” is used for very different types of mobile phones. In our article we therefore propose a comprehensive taxonomy for mobile terminals that clearly distinguishes between different classes of terminals. 1 MOBILE TERMINALS is that mobile computing is a rather new technology so a market consolidation like that for personal desk- Everyday life without mobile terminals is almost top computers didn't take place yet.

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.
