This paper explores the relationship between digital games and learning along the continuum from formal to informal learning. Games are an increasingly important component of our learning ecologies but their potential can prove difficult to fully harness due to the downsides of gaming in informal contexts and to the limitations games can present when adopted in formal learning contexts. The aim of this paper is to shed light on the strengths and weaknesses of games for learning, and to gather stakeholder recommendations for the main actors in the field. The adopted research approach is qualitative and participatory, involving players, teachers, parents, researchers and developers. Data from 25 interviews and 11 focus groups yielded insights into the educational, psychological and ethical aspects of play. Results suggest that gameplay influences individuals in a very personal manner, and that its effects cover a wide range of skills, extending to identity development. Hence, to harness this potential, all actors in the ecology need strong awareness of both the affordances and the risks of games, and deep respect for individuals’ LEs. The study has implications for a wide range of actors, including educators, players, researchers, parents, game developers and policymakers. 相似文献

We seek to analyse the notion of structuring resources and their role in shaping mathematical activity, and more broadly to add to our understanding of mathematical epistemologies in workplace settings. Our analysis is of two nursing activities – drug administration and fluid balance monitoring – based on data collected in an in–depth study of paediatric nurses on the ward. In the first activity, we examine ways in which nurses conceptualise ratio and proportion problems, while in the second, we provide a case study of two nurses discussing conflicting strategies when monitoring the fluid balance of a patient. We discuss the ways in which the available resources give mathematical and professional meanings in these situations and draw out some implications for the design of viable didactical strategies in vocational mathematics teaching. 相似文献

In the southern part of Italy, along the National Road 163 (the Amalfi Coastal road), and particularly close to Positano, some stone formations are present with a cylindrical shape (pinnacles) due to the erosion of the rock and the presence of sub-vertical cracking planes in the rocky slope. The landscape beauty and the dangerousness of these pinnacles, more than 10 m in height, leaning on the underlying road, requested a vulnerability study. The dynamic behavior of these natural solids is influenced by the notable mechanical inhomogeneity due to the nature of the rock, to the presence of diffused crack patterns and to the position along the slope. Some inspections have been performed to have a detailed survey of the pinnacles, using the Laser Scanner 3D technique and with the collaboration of geologist-mountain climbers; some rock specimens have also been taken to be analyzed and tested. The specific weight, the tensile (for bending) strength and the compressive strength, as well as the Young Modulus, considering various directions with respect to cracking planes, were analyzed during laboratory tests on the specimens sampled on site. Different structural modeling to analyze the seismic vulnerability of the pinnacles have been performed and compared: starting from simplified mechanical models of rigid blocks, passing through elastic analyses and finally to finite element (FEM) analyses. Numerical dynamic and static analyses, particularly, the modal dynamic analyses for the elastic continuum and the non-linear static analyses, considering both cracking and plasticity behavior of the rock have been performed. The analyses concerned the pinnacles both under the actual in-situ conditions and according to some strengthening interventions to evaluate the effectiveness and safety of the design. 相似文献

According to the literature, in recent years, developing experiential learning has fulfilled the requirement of a deep understanding of lean philosophy by engineering students, demonstrating the advantages and disadvantages of some of the key principles of lean manufacturing. On the other hand, the literature evidences how some kinds of game-based experiential learning overlook daily difficulties, which play a central role in manufacturing systems. To fill the need of a game overcoming such lack of vision, an innovative game direct in-field, named Kart Factory, has been developed. Actual production shifts are simulated, while keeping all the elements peculiar to a real production set (i.e. complexity, effort, safety). The working environment is a real pedal car assembly department, the products to be assembled have relevant size and weight (i.e. up to 35 kg approximately), and the provided tools are real production equipment (e.g. keys, screwdrivers, trans-pallets, etc.). Due to the need to maximise the impact on students, a labour-intensive process characterises the production department. The whole training process is based on three educational principles: Experience Value Principle, Error Value Principle, and Team Value Principle. As the ‘learn by doing’ and ‘learn by failing’ are favoured, the theory follows the practice, while crating the willingness to ‘do’ instead of just designing or planning. The gathered data prove the Kart Factory's effectiveness in reaching a good knowledge of lean concepts, notwithstanding the students’ initial knowledge level. 相似文献

Subjectivity detection is a task of natural language processing that aims to remove ‘factual’ or ‘neutral’ content, i.e., objective text that does not contain any opinion, from online product reviews. Such a pre-processing step is crucial to increase the accuracy of sentiment analysis systems, as these are usually optimized for the binary classification task of distinguishing between positive and negative content. In this paper, we extend the extreme learning machine (ELM) paradigm to a novel framework that exploits the features of both Bayesian networks and fuzzy recurrent neural networks to perform subjectivity detection. In particular, Bayesian networks are used to build a network of connections among the hidden neurons of the conventional ELM configuration in order to capture dependencies in high-dimensional data. Next, a fuzzy recurrent neural network inherits the overall structure generated by the Bayesian networks to model temporal features in the predictor. Experimental results confirmed the ability of the proposed framework to deal with standard subjectivity detection problems and also proved its capacity to address portability across languages in translation tasks. 相似文献

Innovative strategies in inquiry-based learning are recognized as improving the quality of higher education learning, but
there is a need to explore whether and how these strategies promote the development of professional identity among undergraduates.
In this article we describe an inquiry-based course, situated in a European context, which is designed to support students’
professional identity development through reflective practice; and we present the assessment of students’ learning outcomes.
Results highlight the key roles of field research, peer groups, and a narrative approach in promoting positive student attitudes
toward reflecting on their production of knowledge and in developing their professional identity. 相似文献

Abstract This paper looks at the way RAI (Italian Radio) was used to transmit computer programs, and how it helped when the school leaving age was raised in Italy in the 1950s. It also looks at RAI's position vís‐à‐vís the teacher, in which they are joint leaders with complementary functions. 相似文献

Suppose there is a scientist that writes a paper for a peer-reviewed journal. How likely is it that a natural disaster will terminate, change, suspend or discontinue some aspect of this editorial process? To answer this question, the aim of present study was to determine the effects of a natural disaster on progress in materials science research. The Tsunami event in Japan and materials science are well suited to serve as a case study for both the development and application of a system to evaluate the Academic Research Output immediately after a natural disaster. In particular, the analysis focused on the short-term impacts of Japan's triple disaster – earthquake, Tsunami, and nuclear accident (11 March, 2011) – on the Academic Research Output in materials science subject from three different areas: Sendai (Miyagi Prefecture), Tsukuba (Ibaraki Prefecture) and Kyoto (Kyoto Prefecture). The last one has been used as an internal reference standard (normal/non-disaster situation) for the comparison. A geographical cluster-based study was conducted between 09 February and 10 April 2011. Consistent with the hypothesis that a disaster might slow down knowledge production, the conclusion showed that the Japan's triple disaster strongly influenced the Academic Research Output of papers in the selected field of science. Using statistical data, these findings show that the number of submitted papers and the cumulative number of authors contributing to the field of materials science decreased immediately after the March 11th events in the areas affected by disaster. 相似文献
