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.

Mind The Plug! Laptop-User Recognition Through Power Consumption

Abstract: The Internet of Things (IoT) paradigm, in conjunction with the one of smart cities, is pursuing toward the concept of smart buildings, i.e., ``intelligent'' buildings able to receive data from a network of sensors and thus to adapt the environment. IoT sensors can monitor a wide range of environmental features such as the energy consumption inside a building at fine-grained level (e.g., for a specific wall-socket). Some smart buildings already deploy energy monitoring in order to optimize the energy use for good purposes (e.g., to save money, to reduce pollution). Unfortunately, such measurements raise a significant amount of privacy concerns.In this paper, we investigate the feasibility of recognizing the pair laptop-user (i.e., a user using her own laptop) from the energy traces produced by her laptop. We design MTPlug, a framework that achieves this goal relying on supervised machine learning techniques as pattern recognition in multivariate time series. We present a comprehensive implementation of this system and run a thorough set of experiments. In particular, we collected data by monitoring the energy consumption of two groups of laptop users, some office employees and some intruders, for a total of 27 people. We show that our system is able to build an energy profile for a laptop user with accuracy above 80%, in less than 3.5 hours of laptop usage. To the best of our knowledge, this is the first research that assesses the feasibility of laptop users profiling relying uniquely on fine-grained energy traces collected using wall-socket smart meters.

Learning consumption: Media, literacy, and the legacy of One Laptop per Child

Abstract: This article examines one of the largest interventions in computer-based learning currently underway, the One Laptop per Child OLPC project, with 2.5 million laptops in use worldwide. Drawing on 2010 and 2013 fieldwork investigating a project in Paraguay with 10,000 of OLPC's “XO” laptops, I explore the ways in which participants interpreted leisure laptop use as “learning.” I show that the most captivating uses of the laptops were not “productive” or programming-centric, as OLPC's developers hoped, but “consumptive” and media-centric, focused on music, videos, and video games. I discuss the learning benefits and drawbacks of this use, as understood by participants and in light of education research, and in light of the broader context of transnational corporations interested in marketing to these children. In the process, I weigh OLPC's utopian dreams against the interests of the child beneficiaries, concerns of media imperialism, and a potential shift in the meaning of computers.

Dual screen haptic enabled convertible laptop

Abstract: A dual display client apparatus includes a pair of display housings. When physically coupled together in a first mode of operation, the display housings may be arranged as a single portable electronic device such as a clamshell laptop. In this mode, the system is configured to share computing power and other resources among the two housings, providing a more powerful and robust device than when the housings are separated. Processor power and storage capacity may be aggregated in the unitary apparatus. Battery charging and power sharing may be enabled between the devices' power supplies. When decoupled, the separate display housings are configured to each operate as a self-sufficient, standalone computing device. In this mode of operation, applications and other software may be instantiated as shared instance or separate instances, giving the user of each device ultimate flexibility in device operation and content consumption.

Trends in home computing and energy demand

Abstract: Household energy demand due to domestic computer usage has changed beyond recognition over the past thirty years. Computers are now used in most homes, almost every day and laptop ownership has overtaken traditional desktop computers. Mobile devices give access to services that in the past required desktops, and they are usually more energy efficient. Today's computers usually rely on wireless routers that are often run all day. The effect of these changes on electricity use in the home has been profound. At least 60% more electricity was used for UK home computing in 2012 than in 1990. The implications of recent changes in information technology use are assessed for domestic electricity use and carbon emissions, using data from the Household Electricity Survey (HES) – the most detailed survey of electricity consumption in UK homes. On average, routers use twice as much energy per day as the laptops they serve. Laptops also draw power at a different time of day compared with desktop computers – which has ...

Penerapan metode weighted product dalam sistem pendukung keputusan pemilihan laptop berbasis web

Abstract: Lack of knowledge and information of laptop specifications make common people who want to buy a laptop feel confused to decide which laptop that suits their needs. One way to help prospective buyers in order to select a laptop that suits their needs is to build a system with a web-based decision support system Weigthted Product is a method that uses multiplication to connect the attribute value, where the value should be raised to advance with the corresponding attribute weights. Weighted Product (WP) is part of the concept of Multi-Attribute Decision Making (MADM) where normalization is necessary in the calculation. This system requires the input of weighting value based on the needs of prospective buyers in the form of price, RAM capacity, type of processor, hard drive capacity, and Video Grapphics Array (VGA). The result of this research is to give suggestions on laptops based on the specifications described by the perspective buyer with 100% accurate calculations, either manually or within the decision-support system.

Assessing Laptop Use in Higher Education: The Laptop Use Scale.

Abstract: The laptop computer is considered one of the most used and important technological devices in higher education, yet limited systematic research has been conducted to develop a measure of laptop use in college and university. The purpose of the following study was to develop a research-based, theoretically grounded scale to assess student use of laptops inside and outside higher education classrooms. The Laptop Use Scale addressed four key areas: in-class academic use, in-class non-academic use, outside of class academic use, and outside of class non-academic use. Tested on 156 higher education students using laptops computers, the Laptop Use Scale showed acceptable internal reliability and good validity (face, content, construct, and convergent validity). It is argued that this scale can help assess and calibrate pedagogical strategies used to integrate laptops into higher education classrooms. Suggestions for future research on assessing student use of laptops are offered including a focus on multi-tasking behavior.

DiskFiltration: Data Exfiltration from Speakerless Air-Gapped Computers via Covert Hard Drive Noise.

Abstract: Air-gapped computers are disconnected from the Internet physically and logically. This measure is taken in order to prevent the leakage of sensitive data from secured networks. In the past, it has been shown that malware can exfiltrate data from air-gapped computers by transmitting ultrasonic signals via the computer's speakers. However, such acoustic communication relies on the availability of speakers on a computer. In this paper, we present 'DiskFiltration,' a covert channel which facilitates the leakage of data from an air-gapped compute via acoustic signals emitted from its hard disk drive (HDD). Our method is unique in that, unlike other acoustic covert channels, it doesn't require the presence of speakers or audio hardware in the air-gapped computer. A malware installed on a compromised machine can generate acoustic emissions at specific audio frequencies by controlling the movements of the HDD's actuator arm. Digital Information can be modulated over the acoustic signals and then be picked up by a nearby receiver (e.g., smartphone, smartwatch, laptop, etc.). We examine the HDD anatomy and analyze its acoustical characteristics. We also present signal generation and detection, and data modulation and demodulation algorithms. Based on our proposed method, we developed a transmitter on a personal computer and a receiver on a smartphone, and we provide the design and implementation details. We also evaluate our covert channel on various types of internal and external HDDs in different computer chassis and at various distances. With DiskFiltration we were able to covertly transmit data (e.g., passwords, encryption keys, and keylogging data) between air-gapped computers to a smartphone at an effective bit rate of 180 bits/minute (10,800 bits/hour) and a distance of up to two meters (six feet).

The Fundamental Reasons Why Laptop Computers should not be Used on Your Lap

Abstract: 800x600 As a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. Today laptops are a great tool for education and learning, work and personal multimedia. Millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). Over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons and Magnetic Resonance Imaging (MRI). Our own studies as well as the studies performed by other researchers indicate that using laptop computers on the lap adversely affects the male reproductive health. When it is placed on the lap, not only the heat from a laptop computer can warm men’s scrotums, the electromagnetic fields generated by laptop’s internal electronic circuits as well as the Wi-Fi Radiofrequency radiation hazards (in a Wi-Fi connected laptop) may decrease sperm quality. Furthermore, due to poor working posture, laptops should not be used on the lap for long hours. Normal 0 false false false EN-US X-NONE AR-SA

Learning from the Learners: Preparing Future Teachers to Leverage the Benefits of Laptop Computers

Abstract: Technology is changing the teaching and learning landscape. Teacher preparation programs must produce teachers who have new skills and strategies to leverage the benefits of laptop computers in their classrooms.

A New Technique for Optimizing Resource Allocation and Data Distribution in Mobile Cloud Computing

Abstract: The emergence of mobile cloud computing (MCC) brings benefits to mobile users and cloud providers. However, due to the inherent limitations of the device such as battery life time, CPU and memory capacity, a mobile thin client device ( e.g. smart phones, tablets, iWatch, Google Glass, etc ) cannot meet the requirements of some demanding applications. To alleviate this limitation, the mobile device should cooperate with external resources to increase its performance. Recently, current research approaches have been unable to offer an efficient, seamless computing experience. In this paper, we present a comprehensive thin-thick client collaboration that involves conventional desktop or laptop computers, known as thick clients, by allowing the thin client to borrow resources from thick clients, particularly for optimizing data distribution and utilizing MCC resources to meet Service-Level Agreements, Quality-of-Service requirements and cloud service customers’ budget. Our work uses both numerical analysis and simulation to prove that our proposed architecture can improve resource allocation efficiency and achieve better performance than other existing approaches in some cases.

Time and space dimensions of computer laptop use amongst third year students of the University of the Free State

Abstract: T To broaden the knowledge base of occupation, therapists should understand how spaces, objects and time components support, shape and inhibit occupational performance. The aim of this study was to describe the spatial and temporal dimensions of laptop use amongst students at the University of the Free State in 2013. A descriptive study design was conducted amongst a sample of 216 third year students who make use of a laptop computer for academic and/or recreational purposes. Data were collected by means of an anonymous self-administered questionnaire in which the spatial and temporal dimensions were investigated. Student’s postural configurations were identified and prioritised according to frequency of preference. The three most preferred positions during the academic year were sitting at a table on a chair with backrest (39.8%), sitting with one’s back against a vertical surface (17.6%) and lying on one’s back (11.1%). The median time spent on a laptop was 38.5 hours per week, which occurred in a variety of spatial contexts. Specific postural configurations and time components relative to the occupation of laptop use are conceptualised in this study. Recommendations call for a study to investigate the association between the preferred postural configurations and postural risks with the use of laptop computers. Key words: Laptop, university students, occupational therapy, spatial dimension, temporal dimension, technology.

Evaluation of a Secure Laptop-Based Testing Program in an Undergraduate Nursing Program: Students' Perspective.

Abstract: Recently, the many robust learning management systems, and the availability of affordable laptops, have made secure laptop-based testing a reality on many campuses. The undergraduate nursing program at the authors' university began to implement a secure laptop-based testing program in 2009, which allowed students to use their newly purchased laptops to take quizzes and tests securely in classrooms. After nearly 5 years' secure laptop-based testing program implementation, a formative evaluation, using a mixed method that has both descriptive and correlational data elements, was conducted to seek constructive feedback from students to improve the program. Evaluation data show that, overall, students (n = 166) believed the secure laptop-based testing program helps them get hands-on experience of taking examinations on the computer and gets them prepared for their computerized NCLEX-RN. Students, however, had a lot of concerns about laptop glitches and campus wireless network glitches they experienced during testing. At the same time, NCLEX-RN first-time passing rate data were analyzed using the χ2 test, and revealed no significant association between the two testing methods (paper-and-pencil testing and the secure laptop-based testing) and students' first-time NCLEX-RN passing rate. Based on the odds ratio, however, the odds of students passing NCLEX-RN the first time was 1.37 times higher if they were taught with the secure laptop-based testing method than if taught with the traditional paper-and-pencil testing method in nursing school. It was recommended to the institution that better quality of laptops needs to be provided to future students, measures needed to be taken to further stabilize the campus wireless Internet network, and there was a need to reevaluate the Laptop Initiative Program.

Everyday personal laptop usage in secondary schools in Trinidad and Tobago

Abstract: The e-Connect And Learn (eCAL) programme is a Trinidad and Tobago government-led initiative, launched in 2010, that grants personal laptop computers to students entering secondary school. The purpose of this paper is to provide a snapshot of how students are using these government-issued personal laptops 3 years after the programme's launch. This paper explores the fissure between what the policy recommends and what is actually enacted in the context of laptop usage in the classroom. Data were drawn from 1,451 students, from 32 secondary schools across Trinidad and Tobago. Responses indicate that students are falling short of the expectations for in-class laptop usage and in schools where usage is less often but on a regular basis, laptops are mainly used for technology-related subjects. These findings not only suggest that students' everyday personal laptop usage in the classroom is not in alignment with the eCAL programme goals, but also highlight some of the issues to be considered by other countries when implementing large-scale laptop programmes.

User defined custom virtual keyboard

Abstract: At present, the smart phones are mostly touch based, and they don't have an input hardware (keyboard) associated with them. Also, the software keyboard present in these smart devices, are very small as compared to desktop/laptop. This results in slow typing and also, causing inconvenience for the disabled people. In the smart devices (mobile, tablets, TV etc.), a hardware keyboard is missing. There are few solutions for making virtual keyboard but those solutions are not customizable and accurate enough with existing phone's hardware. Some solutions like laser keyboard which can be used as an alternative to hardware keyboard are there, but it requires an extra hardware to carry along with your device. Also, using specialized 3D cameras can be an alternative to the above problem. This paper defines new way of developing a virtual and custom keyboard, using 2D camera and other sensors available in phone, without the use of any extra input hardware. This implementation enables users to create his keyboard on any homogenous surface like table or paper.

Text entry of physical and virtual keyboards on tablets and the user perception

Abstract: We examined the text entry speed on a tablet for users using physical and software keyboards; a Bluetooth keyboard, a default software keyboard and a gesture based keyboard. We compared these to a laptop and measured adjusted words per minute and error rate. User perceptions were gathered to see if there was a noticeable difference between text entry speeds and how users viewed each keyboard's accuracy, frustration and ease of use. We found was that while there was a difference in entry speed between virtual and physical keyboards, there was no difference in speed between physical keyboards or between software keyboards. There was limited error difference between all keyboards. However despite the Bluetooth keyboard being closest to the laptop in results, user preference was greater for the gesture keyboard.

The Laptop Accordion.

Abstract: The“Laptop Accordion”co-opts the commodity laptop computer to craft an expressive, whimsical accordion-like instrument. It utilizes the opening and closing of the laptop screen as a physical metaphor for accordion bellows, and the laptop keyboard as a musical buttonboard. Motion is tracked using the laptop camera via optical flow and mapped to continuous control over dynamics, while the sound is generated in real-time. The instrument uses both skeuomorphic and abstract onscreen graphics which further reinforce the core mechanics of “squeezebox” instruments. The Laptop Accordion provides several game modes, while overall offering an unconventional aesthetic experience in music making.
