Method, system and devices for wireless data storage on a server and data retrieval

Abstract: A method and system for remotely storing data on a server through a wireless connection instead of storing data locally in a consumer device, as well as devices for use with the method and system. More particularly, a video camera, still camera, laptop computer, or other consumer device which normally stores data in local memory such as film, disk, random access memory, memory sticks, or other forms of storage would transmit the data to a remote server through a wireless connection. The data would be saved on the remote server for subsequent retrieval through, for example, the Internet or a wireless connection to the server. In addition, data not originating from the user device could be downloaded to the consumer device. The data to be retrieved can be specified by the user, or sent to the user according to a user profile stored on the server.

Learning in One-to-One Laptop Environments A Meta-Analysis and Research Synthesis

Abstract: Over the past decade, the number of one-to-one laptop programs in schools has steadily increased. Despite the growth of such programs, there is little consensus about whether they contribute to improved educational outcomes. This article reviews 65 journal articles and 31 doctoral dissertations published from January 2001 to May 2015 to examine the effect of one-to-one laptop programs on teaching and learning in K–12 schools. A meta-analysis of 10 studies examines the impact of laptop programs on students’ academic achievement, finding significantly positive average effect sizes in English, writing, mathematics, and science. In addition, the article summarizes the impact of laptop programs on more general teaching and learning processes and perceptions as reported in these studies, again noting generally positive findings.

One-to-one computing: what does it bring to schools?

Abstract: This study investigates students’ use of one-to-one laptops for various activities and the impact of one-to-one computing on student learning and school culture. Based on data collected from surveys and interviews of teachers, students, and parents in a Midwestern middle school over one academic year, this study answers the following major questions: 1) How did students use their laptops? 2) What impact did the one-to-one laptop program have on student learning and school culture? 3) What were the perceptions of and concerns over one-to-one computing? A sound understanding of these issues is increasingly important as more and more schools are joining in this one-to-one computing initiative and more money is being invested. Results revealed that students used their laptops for various tasks related to learning, communication, expression, and exploration. Students gained significantly in their technology proficiency. The one-to-one laptops have provided great opportunities and resources for teaching and learning, but also raised issues such as student discipline problems, concerns on digital literacy, and fear of over-dependency on information technology.

Learning with Laptops: Implementation and Outcomes in an Urban, Under-Privileged School

Abstract: This study examined the implementation and outcomes of a laptop program initiative in a predominantly low-income, minority school. Both quantitative and qualitative data were collected, analyzed, and compared with students in non-laptop classrooms within the same school. Results of the study revealed that in the hands of well prepared teachers, laptops enabled disadvantaged students to engage in powerful learning experiences. Although quantitative data did not reveal significant differences in student attitudes towards computers and school between laptop and comparison students, qualitative data indicated that laptop integration created enhanced motivation and engagement with schoolwork, influenced classroom interactions, and empowered students. Such behaviors were not evident among comparison students. Furthermore, qualitative data indicated that the laptop program produced academic gains in writing and mathematics within the laptop group. Results of the study have implications for policy makers,...

Database system issues in nomadic computing

Abstract: Mobile computers and wireless networks are emerging technologies that will soon be available to a wide variety of computer users. Unlike earlier generations of laptop computers, the new generation of mobile computers can be an integrated part of a distributed computing environment, one in which users change physical location frequently. The result is a new computing paradigm, nomadic computing. This paradigm will affect the design of much of our current systems software, including that of database systems.This paper discusses in some detail the impact of nomadic computing on a number of traditional database system concepts. In particular, we point out how the reliance on short-lived batteries changes the cost assumptions underlying query processing. In these systems, power consumption competes with resource utilization in the definition of cost metrics. We also discuss how the likelihood of temporary disconnection forces consideration of alternative transaction processing protocols. The limited screen space of mobile computers along with the advent of pen-based computing provides new opportunities and new constraints on database interfaces and languages. Lastly, we believe that the movement of computers and data among networks potentially belonging to distinct, autonomous organizations creates serious security problems.
