ABSTRACTThe development of Information and Communication Technology has created waves of excitement about its power to fix educational problems and improve learning results, prompting a succession of policy efforts to integrate digital technology into education. Educators, schools and corporations are increasingly driving these initiatives. This article makes the argument that a narrow vision of digital technology, which both ignores the complexity of education and wastes valuable public resources, is becoming an obstacle to significant improvement and transformation in education. Utilising our research and experience in the field of educational technology, this paper problematises the common elision of ‘technology’ and ‘digital technology’. From this basis, we then critically reflect on various common approaches to introducing digital technology in education under the guise of promoting equality and digital inclusion. These include national government-led programmes, more recent trends for local school-led initiatives, and the role of non-formal education initiatives led by corporations/foundations. Amidst the varying surface-level ‘failure’ and/or ‘success’ of these approaches, we point to limited underpinning ‘information and knowledge society’ logics in framing the application of digital technology to education. As such we conclude by considering the educational challenges for future Ed-Tech initiatives. 相似文献

RESUMENEn la Argentina de mediados del siglo XX comenzó con un fuerte sesgo estatal a pensarse en la cinematografía escolar como un eficaz método pedagógico de difusión de un pretendido ideario simultáneamente emancipador y propagandístico. Del mismo modo que otros gobiernos de diversas filiaciones ideológicas, la presidencia de Juan Domingo Perón estuvo signadas por una política de la imagen que se enfocó en educar los sentidos de las futuras generaciones de argentinos. En este caso se muestra una política en particular, como lo fue la revista Noticioso entre 1952 y 1955, cuyo análisis refleja el exponencial crecimiento del rol estatal, hasta ocupar un lugar central no sólo en la reproducción de cine educativo, sino también de la filmación, distribución y proyección de los celuloides. En síntesis, con la creación en 1948 del Departamento de Radioenseñanza y Cinematografía Escolar como organismo específicamente dedicado a la enseñanza audiovisual, y especialmente con la publicación de Noticioso, puede verse un síntoma de las políticas gubernamentales que el peronismo forjó para la formación de nuevos ciudadanos, en el marco de la pretendida Nueva Argentina. 相似文献

Forty-one practitioners inclusive of physiotherapists, sports scientists and strength and conditioning coaches from the academies of elite soccer clubs in the United Kingdom completed an on-line questionnaire which examined their: (1) background information; (2) perceptions of injury occurrence and risk factors; (3) screening and return to play; and (4) approach to designing and delivering injury prevention programmes with a response rate of 55% (41/75). Contact injuries were the most common mechanism reported and players between 13–16 years of age were perceived to be at the greatest risk. Pertinent risk factors included: reduced lower limb and eccentric hamstring strength, proprioception, muscle imbalances, and under developed foundational movement skills. Joint range of motion, jump tests, the functional movement screen, overhead and single leg squats were the most utilised screening methods. Training modalities rated in order of importance included: resistance training, flexibility development, agility, plyometrics and balance training. Training frequency was most commonly once or twice per week, during warm-ups, independent sessions or a combination of both. Injury prevention strategies in this cohort appear to be logical; however, the classification of injury occurrence and application of screening tools to identify “at risk” players do not align with existing research. The frequency and type of training used may also be insufficient to elicit an appropriate stimulus to address pertinent risk factors based on current recommendations. 相似文献

Due to its importance in fitness centers, a number of authors have explored and analyzed loyalty. However, two characteristics not yet examined are service convenience in fitness center chains and low-cost fitness centers (an emerging business model). In the present study, the authors sought to understand the relationship among perceived quality and service convenience on perceived value, satisfaction, and client loyalty in low-cost fitness centers. Clients (N = 763; 381 women and 382 men) from three low-cost Spanish fitness centers were surveyed, revealing a positive relationship among the variables studied. Findings demonstrate the importance of proper management of non-monetary sacrifices and perceived quality by the managers of these sport organizations, since client loyalty could depend on factors of these emerging sport models. 相似文献

This article argues that a mutual shaping lens enables a more encompassing account of the joint processes of technological and social change in new media than the diffusion of innovations and social shaping of technology perspectives. Drawing from recent work in sociology and history of technology, organization studies, social informatics, and computer-supported cooperative work, this article suggests that the shaping and diffusion of media artifacts are so intimately tied that they should be seen as the two sides of the same innovation coin. Using examples from the history of videotex newspapers in the United States, the analysis shows that actors simultaneously pursued interdependent technological and social transformations, that this was an ongoing process in which partial outcomes in the technological domain influenced social events at a later phase—and vice versa—and that such process was influenced by historical developments. 相似文献

There is an increasing consensus in the Recommender Systems community that the dominant error-based evaluation metrics are insufficient, and mostly inadequate, to properly assess the practical effectiveness of recommendations. Seeking to evaluate recommendation rankings—which largely determine the effective accuracy in matching user needs—rather than predicted rating values, Information Retrieval metrics have started to be applied for the evaluation of recommender systems. In this paper we analyse the main issues and potential divergences in the application of Information Retrieval methodologies to recommender system evaluation, and provide a systematic characterisation of experimental design alternatives for this adaptation. We lay out an experimental configuration framework upon which we identify and analyse specific statistical biases arising in the adaptation of Information Retrieval metrics to recommendation tasks, namely sparsity and popularity biases. These biases considerably distort the empirical measurements, hindering the interpretation and comparison of results across experiments. We develop a formal characterisation and analysis of the biases upon which we analyse their causes and main factors, as well as their impact on evaluation metrics under different experimental configurations, illustrating the theoretical findings with empirical evidence. We propose two experimental design approaches that effectively neutralise such biases to a large extent. We report experiments validating our proposed experimental variants, and comparing them to alternative approaches and metrics that have been defined in the literature with similar or related purposes. 相似文献

The southernmost area of Texas, known as the Rio Grande Valley, is largely absent from histories of early radio. The social, political, and economic history of the Valley from 1848 to the 1950s prompts the authors to approach the region’s broadcast history from the context of rural and farm radio. The papers of broadcaster Bradford Smith, housed at the Margaret H. McAllen Memorial Archives at the Museum of South Texas History, provide an entryway for Valley radio to become part of the larger body of rural and farm radio scholarship. Smith’s radio reports emphasize the centrality of localism for remote communities, and they provide competing narratives about the region’s modern identity and its Mexican roots. 相似文献

This paper aims to contribute to the analysis of within industry inter-firm variety. The paper develops two themes: (i) the analysis of intra-industry heterogeneity, and (ii) the extent to which higher performance is associated with the capacity of firms to expand their knowledge base. The main contribution of the paper is empirical, based on a data source consisting of information on documents published in international scientific journals by Spanish pharmaceutical firms. The empirical results support the argument that the firm's knowledge base is a main driver of persistent heterogeneity within industries. We find systematic variety in terms of how firms articulate their research activities, and positive correlation between firms’ knowledge diversification and performance. 相似文献
