On February 1st 2011 (Census Day), 18,059 Italians lived in Luxembourg and made up 3.5% of the total population. Their number has decreased since 1970. In that year 23,490 Italians (6.9% of the total population) are still counted. In 1960, Italians accounted for 37.8% of all foreigners living in Luxembourg. In 2011, the Italians account only for 8.2% of the foreign citizens living in Luxembourg. In comparison with the general population, the Italians are much older on average (45.2 years for Italians, against 38.7 years on average for the total population). The majority of Italians living in Luxembourg was born in Italy (62.7%). 28.3% were born in Luxembourg. In absolute terms, most Italians live in the City of Luxembourg (5 750, nearly 30% of all Italians living in the Grand Duchy). However, their relative proportion in the population is the largest in Bertrange (7.0% of the population of the municipality, against 3.5% at the national level). Overall, the Italians have a lower level of formal education than the total population on average. However, young Italians have more often higher levels of education than people of the same age in the total population. [less ▲]

The present paper investigates translanguaging practices and types of talk of 6 to 8 year-old multilinguals who record texts on the App iTEO in Luxembourg. ITEO enables users to record and edit oral text, to listen to recordings and to structure the recording process. The automatic playback materializes the language and provides opportunities for reflection. The collective process of recording and transforming texts presents children with opportunities to use exploratory talk proven to stimulate learning (Mercer 2000, 2004). Our qualitative longitudinal study focuses on the use of iTEO for teaching and learning languages in nursery and primary schools (http://storying.bsce.uni.lu/). The study’s multi-method approach, with data collected over two years, includes: observations of activities involving iTEO, video recording of children`s storying, interviews with all participants and the collection of documents. The data analysis followed the principles of Grounded Theory (Charmaz 2006, Strauss & Corbin 1990) and was assisted by the programme Nvivo. Findings have shown that children develop linguistic and metalinguistic competences and that they translanguage regularly while working with iTEO (Gretsch 2014, Kirsch & Gretsch, 2015). In this paper, we discuss a case study of children in the first grades of primary school with the following purposes: 1. To identify instances of translanguaging; 2. To analyze the different kinds of discourse emerging during the co-construction of text on iTEO; and 3. To show how these contribute to learning. We argue that iTEO creates a translanguaging space (García & Wei 2014), where children can draw on their entire repertoire in order to learn. Embedded in multilingual pedagogies, iTEO helps learners to co-construct linguistic knowledge through different types of talk. The results of our case study will contribute to a deeper understanding of the ways in which multilingual children translanguage and use different types of talk in autonomous, collaborative and computer-assisted activities.

iTEO ist eine iPad App, die es ermöglicht, Sprache aufzunehmen und Texte (Wörter, Sätze) zu editieren. Wir setzten iTEO in verschiedenen Grundschulklassen in Luxemburg ein, um zu untersuchen, wie Kinder und Lehrpersonen das Tool zur Sprachförderung im Unterricht einsetzen. Die Ergebnisse unserer Studien zeigen, dass Kinder, die gemeinsam mit Kameraden Geschichten erzählten, ihre Sprache entwickelten (z.B. Wortschatz, Grammatik, diskursive Kompetenzen), sich metalinguistisches Wissen aneigneten und Lernstrategien erwarben. [less ▲]

Luxembourg’s multilingualism and multiculturalism are reflected both in its trilingual education system and its diverse school population. However, despite the official policy of trilingualism, language learning programmes tend to be underpinned by a monoglossic view that sees languages as autonomous skills that need to be developed separately. Statistics have repeatedly shown that ethnic minority children, 48% of the school population, underachieve. In response, the ministry of Education has developed approaches to further the development of multiple languages. However, these are neither sufficiently specific nor systematic. Our project addresses the need for the development of appropriate didactics and of innovative strategies to cope with the diversity and heterogeneity in Luxembourg’s schools. We believe in working with rather than against the diversity of the school population and base our understanding of language learning on sociocultural theories. We investigate how young children of ethnic minority background learn Luxembourgish, German and French through collaborative storytelling on the iPAD App iTEO and how teachers support their learning with this new technology. The App iTEO is a learning-and-teaching tool that records and edits language. It structures the learning process, mediates language learning and promotes metalinguistic awareness. Findings of the pilot study have shown that the tool facilitates children’s collaborative, exploratory and open-ended language learning and allows children to draw on their diverse language repertoires and to deploy a range of strategies.

The sequencing process of a DNA chain for reading its components supposes a complex process, since only small DNA fragments can be read nowadays. Therefore, the use of optimization algorithms is required to rebuild a single chain from all the small pieces. We address here a simplified version of the problem, in which no errors in the sequencing process are allowed. The methods typically used in the literature for this problem are not satisfactory when solving realistic size instances, so there is a need for new more efficient and accurate methods. We propose a new iterated local search algorithm, highly competitive with the best algorithms in the literature, and considerably faster. [less ▲]

This paper introduces a new iterative approach to solve or to approximate the solutions of the nonconvex quadratically constrained quadratic programs (QCQP). First, this constrained problem is transformed to an unconstrained problem using a specialized penalty-based method. A tight upper-bound for the alternative unconstrained objective is introduced. Then an efficient minimization approach to the alternative unconstrained objective is proposed and further studied. The proposed approach involves power iterations and minimization of a convex scalar function in each iteration, which are computationally fast. The important design problem of multigroup multicast beamforming is formulated as a nonconvex QCQP and solved using the proposed method. [less ▲]

Different approaches have been proposed on the design and development of digital and interactive technology in mobile learning contexts. In line with recent findings in literature, we suggest that mobile learning systems benefit from a criteria-based iterative design and development process that incorporates evaluation results of mobile learning scenarios based on school curricula. Underlying these scenarios is a holistic, socio-technical system view, which makes allowance for the complex dynamics between teachers, students, researchers, the multiplicity of contextual factors, and the specifications and requirements of the digital devices and applications, as well as their interrelations. Five school project scenarios are described, as well as the evaluation process involved that served as an integral part in creating a dynamic optimization process for the design and development of digital and interactive systems that follow efficiency criteria for mobile learning (i.e., construction, contextualization, communication, and control). In addition, we argue that mobile systems should also allow for users’ or students’ participatory activities in the preparation phase to bridge the gap between indoor and outdoor learning. [less ▲]
