Embodied Composition in Real Virtualities: Adolescents’ Literacy Practices and Felt Experiences Moving with Digital, Mobile Devices in School

English educators are contending with the proliferation of mobile devices in students’ lives, and with the imminent integration of mobile devices into classrooms. Concurrently, literacy researchers using social semiotic theories of multimodality to investigate adolescents’ digital composing have focused on screens, paying scant attention to the bodies moving with them. Responding to recent critiques of multimodality that have centered on a lack of attention to embodiment and affect, this article leverages the concept of real virtualities to avoid artificially bifurcating screen and body, and to contribute a beginning theorization of the embodied experience of composing with mobile devices, which includes feeling-histories, affective atmospheres, and the felt experience of time. The data analyzed in this article come from a 12-week enrichment course in which five adolescents composed digital narratives with iPods. The overarching analysis describes all literacy practices with mobile devices in the course, and the microanalysis, using multimodal interaction analysis, compares two students with contrasting histories of mobile device use. Findings show these students’ literacies as more body-centered than techno-centered, and evince tensions between institutionalized learning environments and adolescents’ affective, cultural histories of being mobile while engaged in literacy. Further, findings describe how the feeling of tools and semiotic material influenced the trajectories of students’ bodies and narratives. Theories of digital composition should continue expanding to account for connections between mobility and affect, and the pedagogical importance of motility. The changing nature of literacy in the milieu of mobile computing compels researchers to consider the role of the moving, feeling body in literacy with more scrutiny.

A Component-Level Radio-Frequency Interference Evaluation Method for Mobile Devices

In this letter, a radio-frequency interference (RFI) evaluation method for highly integrated mobile devices, such as smartphones and tablets, is proposed. A near-field specification for noise-emitting components in mobile devices is developed based on near-field emission measurements and RF sensitivity measurements of mobile devices with the bit-error-rate (BER) test. To devise the specification, a derivative relation between the near-field strength of noise sources and the system-level RF sensitivity is newly suggested using the theoretical relationship between the signal to interference and noise ratio and the probability of error in communication systems, and verified with empirical measurements. Using the proposed algorithm, an RFI evaluation specification for commercial camera modules widely used in modern smartphones was established at several RF communication bands.

IGreen: A ubiquitous dynamic network to enable manufacturer independent data exchange in future precision farming

In order to master the future challenges concerning increased demand for food and energy it is obvious that new methods are needed to boost productivity in a sustainable way. One key aspect to optimize agricultural processes and decision making is to derive effective means to acquire and share information along the value chain. In the past, data management in agriculture was dominated by proprietary, mostly Original Equipment Manufacturer (OEM) driven solutions with limited scope. To overcome the shortcomings associated with this, the German national joint research project iGreen was initiated in 2009 to enable convenient and efficient data sharing in a holistic and OEM independent way. As a project partner, John Deere focused on developing concepts and components for interconnecting machines among each other and with infrastructure nodes. In this paper the achieved results such as the infrastructure component referred to as the machine connector, the onboard data management and integration of mobile devices will be presented and evaluated through experiments focusing on data sharing in wheat and forage harvesting. The overall promising results indicate that in the future new applications focusing on optimizing processes can be enabled that will greatly improve the effectiveness and ease of agricultural production, especially fleet management and resource planning.

Integration of Mobile Devices into Ubiquitous Learning by the 21st Century Teenagers

Mobile devices become ubiquitous, affordable and accessible for the 21 st century teenagers, as such they have the chance to perform the learning activities through using mobile devices without the constraint of time and space. Many quantitative studies have been done for investigating the perception of technology use in education, but the studies done do not specifically focus on the use of mobile devices into ubiquitous learning by the teenager especially in Malaysia. Therefore, this research conducted to obtain an in-depth understanding of the usage pattern of these teenagers on their mobile devices and to clarify to what extent they used the mobile devices in performing learning activities. The study also analyses the factors affecting the teenagers from using mobile devices to perform learning and provides a snapshot of the way the teenagers perceive the use of mobile devices qualitatively. The study shows that teenagers possessed positive attitudes towards using mobile devices into performing ubiquitous learning as they see the mobile devices as convenient, fast response and easy to access to knowledge of information. However, using mobile devices to perform ubiquitous learning is much depends on the individual's preference, interest and self-motivation. Learning facts, languages and skills using mobile devices are the most preferable activities among the teenagers.

Qoe Model for Multimedia Content Delivery from Mcloud to Mobile Devices

Integration of mobile devices in the m-learning systems provides the learner with scaffolding outside the classroom, it allows them to easily store, record and deliver multimedia content in real-time. The process of delivering multimedia learning objects (rich text, video, images, audio, animation, etc.) from the mlearning systems to the users requires more computational resources than mobile devices can provide. Considering the existence of different kinds of mobile browsers, which have limited support for HTML plugins (Flash, Java and Silverlight), we face the challenge to deliver the adapted multimedia contents in the interactive m-learning system. Installation of add-ons to the mobile browsers is just a provisional solution that is not always possible on each mobile device. Generally, the m-learning systems presented on the mobile device that not provide rich multimedia information leads to a degraded learning experience. In order to provide users with multimedia content that is suitable for their mobile devices and according to their needs we introduce the mobile cloud computing environment as paradigm that is ideal to overcome these problems. The proposed interactive mCloud system should provide high scale collaboration and interaction between the professor and students, in direction of increasing the quality of learning. The main focus is the delivery of multimedia learning objects to the users depending on the student’s cognitive style and adapting the content in accordance with the context-aware network conditions. The main task within this paper is to design a QoE model for estimating the multidimensional metric based on multimedia content adaptive features.

Emerging Vocabulary Learning: From a Perspective of Activities Facilitated by Mobile Devices

This paper examines the current mobile vocabulary learning practice to discover how far mobile devices are being used to support vocabulary learning. An activity-centered perspective is undertaken, with the consideration of new practice against existing theories of learning activities including behaviorist activities, constructivist activities, situated activities, collaborative activities and informal and lifelong activities. Such an approach allows one to reflect on the advantages of L2 vocabulary learning and to hypothesize what features of this technology are likely to change language teaching and learning.The integration of mobile devices and vocabulary learning needs to take into consideration portability, social interactivity, context sensitivity, connectivity and individuality. Insights gained from the categorization of activity type will inform researchers and teachers of the emerging vocabulary learning practice and its potential relevance to the innovation in language language teaching and learning.

Schools going mobile: A study of the adoption of mobile handheld technologies in Western Australian independent schools

<p>This paper reports on the adoption of mobile handheld technologies in ten Western Australian independent schools, based on interviews with staff conducted in 2011. iPads were the most popular device, followed by iPod Touches and iPhones. Class sets were common at lower levels, with 1:1 models becoming increasingly common at higher levels. Mobile learning, or m-learning, was still at an experimental stage in most schools, but common themes were already emerging around the need to integrate mobile devices into a broader learning ecology. Key discussions focused on their role in promoting consumption or production, collaboration or personalisation, and creating seamless learning spaces. Used for both organisational and pedagogical purposes, mobile devices were seen as enhancing student motivation, with empirical evidence of improved student learning also emerging in small-scale studies conducted by two schools. Challenges included the need to carefully manage the technology, ethical issues in its use, and staff roles in its deployment. Pedagogically grounded and adequately contextualised professional development (PD) was seen as vital for time-poor staff, while a desire to set up a professional community of practice was widely expressed. All the schools surveyed planned to extend their use of mobile handheld technologies in the future.</p>

New ICT tools allow children to take advantage of new learning platforms as well aiding them effectively in attaining new knowledge through activities related to their immediate interests and real life scenarios. Nowadays, computers and digital applications are a part of the daily life of children. In kindergarten education, properly designed digital educational activities can become a very powerful educational tool for efficient and effective learning. The utilization of interactive activities may contribute towards the growth of learning incentives as well as proper mental development in particular areas; such as mathematics and science. Mobile devices have new attractive features and provide considerable advantages in the teaching of mathematics in kindergarten education. Our study proposes the integration of mobile devices, running our own specially designed learning activity applications, in kindergarten classrooms. These applications are based on the three levels of Realistic Mathematics Education (RME) targeting fundamental mathematical concepts for the kindergarten level. We intend to gather information on effectiveness of the incorporation of these devices and applications as leaning tools for kindergarteners.

Robust Reliability Performance of Large size eWLB (Fan-out WLP)

With reducing form-factor and functional integration of mobile devices, Wafer Level Packaging (WLP) is attractive packaging technology with many advantages in comparison to standard Ball Grid Array (BGA) packages. With the advancement of various fan-out WLP, it is more optimal and promising solution compared to fan-in WLP, because it can offer greater flexibility in design of more IOs, multi-chips, heterogeneous integration and 3D SiP. eWLB (embedded wafer level packaging) is a type of fan-out WLP enabling applications that require smaller form-factor, excellent heat dissipations, thin package profile as it has the potential to evolve in various configurations with proven manufacturing capacity and production yield. This paper discusses the recent advancements of robust reliability performance of large size eWLB. It will also highlight the recent achievement of enhanced component level reliability with advanced dielectric materials. After a parametric study and mechanical simulations, new advanced materials were selected and applied to eWLB. Standard JEDEC tests were carried out to investigate component level reliability of large size (9x9~14x14mm2) test vehicles and both destructive/non-destructive analysis were performed to investigate potential structural defects. Daisychain test vehicles were also tested for drop and TCoB (Temperature Cycle on Board) reliability performance in industry standard test conditions. Besides, this paper will also present a study of package level warpage behaviour with Thermo-Moire measurement.

A Template-Based Short Course Concept on Android Application Development

Smartphones are a common accessory to provide rich user experience due to superior memory, advanced software-hardware support, fast processing, and multimedia capabilities. Responding to this trend, advanced engineering systems tend to integrate mobile devices with their solutions to facilitate usability. With many young students showing interest in learning mobile application development, conventional electrical engineering undergraduate education cannot meet the needs of this workforce due to fast changes in mobile technology and limited curricula hours. Templatebased learning (TBL) methods may overcome these limitations by shortening the learning cycle through fast hands-on introduction to development tools, basic programming, and application development and integration process. Students manipulate code fragments in provided templates, and compile, embed, and run applications. They also implement new applications reusing fragments from other similar templates. TBL modules can be integrated in pre-existing conventional courses to provide basic and fast exposure to the subject. This paper provides an example of a TBL template library for Android phones, which has been used in a classroom setting to collect student attitude data and assess efficiency of the TBL approach.

Using Short Message Service (SMS) to teach English idioms to EFL students

AbstractThis study aimed to gauge the efficacy of three modes of instruction of English idioms, ie, Short Message Service (SMS)‐based learning, contextual learning and self‐study learning. More precisely, this study capitalized on the push aspect of SMS affordance to deliver bite‐sized English idiom lessons on spaced intervals to the learners irrespective of the traditionally inherent problems in most teaching classrooms of English as a Foreign Language learning contexts and thus promote regular study. Students' perceptions and attitudes toward mobile learning and the application of SMS in teaching and learning English (idioms) were also sought by conducting a poststudy survey. Overall, the results revealed that students receiving short mini‐lessons on their mobile phones via SMS were more enthusiastic and learned more than their counterparts on paper or contextual groups.Practitioner NotesWhat is already known about this topic Among different functions a mobile phone can afford, its Short Message Service (SMS) has been widely used to transmit and receive general and educational contents. SMS affordance of mobile phones has been used to teach language components such as grammar and vocabulary. The efficiency of teaching English idioms via SMS in comparison with other methods (eg, contextual learning and self‐study approaches) has not been examined in the Mobile Assisted Language Learning practices simultaneously. What this paper adds Gauging the comparative efficacy of SMS‐based instruction of English idioms in contrast with two other instruction modes, ie, contextual learning and self‐study simultaneously. Delivering bite‐sized SMS‐based English idiom lessons to the learners beyond the constraints of the traditional classrooms and promoting regular study. Seeking students' perceptions and attitudes toward mobile learning and the application of SMS in teaching and learning English idioms by conducting a poststudy survey. Implications for practice and/or policy Insights gathered from the comparative integration of mobile devices, particularly mobile phones and its different affordances into teaching classrooms of English as a Foreign Language learning contexts, are considered to have important implications for the educators and technologists to harness the potential of mobile technologies and design appropriate tasks that pave the way for the widespread use of this platform for language learning on a large scale. A deep understanding of the mobile devices used and the possibilities associated with them is needed in order to better design the mobile learning (m‐learning) activities. Embarking on an m‐learning project entails designing particular activities tailored to the needs of students involved in the learning process.

Enhancing team projects using an event-triggered knowledge network

Across the disciplines and levels of education, team projects are becoming an increasingly important tool for assessment. However, it is often difficult to make sure that work is fairly distributed, that a reasonable schedule is formed which does not leave everything for the last minute, and that individual students are fairly rewarded/penalized for their respective contributions. To solve these problems, we can model a project using events, rules, and workflows. Depending on the nature of an event, an appropriate rule can be triggered, which can subsequently initiate a workflow that will assign specific tasks to specific roles within the team. Events that occur over the course of the project, fired from a variety of sources, can lead to the derivation of new knowledge, and potentially alter the flow of the team’s activities. An integration of mobile devices into the system can insure that students are always aware of the current state of the system and their roles within it. At the conclusion and at all prior points in the project lifecycle, a comprehensive log of each student’s activities will be available and will greatly simplify the task of assigning fair and accurate grades. The result will be a more educational, more equitable, and far more engaging learning experience.

Mobile device integration of a fingerprint biometric remote authentication scheme

SUMMARYVarious user authentication schemes with smart cards have been proposed. Generally, researchers implicitly assume that the contents of a smart card cannot be revealed. However, this is not true. An attacker can analyze the leaked information and obtain the secret values in a smart card. To improve on this drawback, we involve a fingerprint biometric and password to enhance the security level of the remote authentication scheme Our scheme uses only hashing functions to implement a robust authentication with a low computation property.

A Risk-Based Classification of Mobile Applications in Healthcare

Mobile devices and applications are becoming popular in today’s society. The number of applications available to both the patient and the healthcare provider is changing the way healthcare is being delivered and consumed. The integration of mobile devices into every-day lives is driving the changes in healthcare. While all areas of medicine are being impacted, changes are mostly of chronic care, long term care and any place that causes a need for constant data, monitoring or training. The acceptance of mobile devices by healthcare consumers within wide range of age and socioeconomic circumstances is reason to look at mobile technology as the future of healthcare. While increased use of mobile applications are welcomed by most providers and consumers alike, there is a need to systematize the study of its use. The authors provide a framework for considering mobile applications in healthcare, based on their risk-profile. They accomplish this by first identifying and classifying the mobile healthcare applications.

Service Component Architecture Extension for Sensor Networks

The role of small electronic devices has been growing over the past years. Many types of devices which allow for interaction with the environment can now be found in the market and there is large set of solutions for integration of mobile devices with enterprise systems. However, most such solutions focus only on providing base services for other SOA system elements. The paper presents an extension of the SCA programming model to include intelligent sensors and a concept of uniform programming model shared between sensor networks and standard computers. The architecture of such an extension is proposed and an initial prototype implementation is presented. The solution utilizes a proxy pattern, validated by a simple case study using Sun SPOTs and Sentilla. The advantages and limitations of the proposed extension are also discussed.
