This article presents our experience of testing the OpenSim platform as a tool in teaching French to 108 tourism students at Universidad Rey Juan Carlos (Madrid, Spain). The article begins with some theoretical reflections on the behaviour of the student when using a virtual platform by means of an avatar, and with our observations of how this doubling of identity is actually the greatest asset of virtual worlds when we intend to apply them to teaching (1. Introduction). Then we move on to present our goals and method of work (2. Aims and methodology) and to analyse the development of the virtual space or sim, setting out the teaching strategies that were employed in each of the islands we created, and which correspond to reading comprehension, listening comprehension and written expression (3. Metaverse design). In order to assess the language learning results, we also devised tests throughout the experiment, which were repeated one month later. The assessment shows that the process of language acquisition is positive (4. Results analysis). Finally, we demonstrate that the rise of virtual worlds has been backed up by psycholinguistic factors, but at the same time their applicability and sustainability depend on technical aspects and very especially on theoretical and pedagogical tenets which are still to be drawn up (5. Conclusions). 相似文献

This paper describes an online early childhood assessment course that was developed through a multi-university collaboration with support from a state improvement grant. Collaborators from three universities developed the course to address a new early childhood unified license (birth to age 8, regular and special education) in the state of Kansas. After reviewing the new state content standards, we identified targeted understandings, performance assessments, and online activities for 15 modules using a backward design process. Emphasis was placed on active learning through synchronous and asynchronous interactions facilitated by the use of a course management system. Positive evidence of learning was indicated by anonymous student feedback, pretest/posttest gain scores, and performance assessments evaluated with rubrics. We viewed the implementation of the course as a success and anticipate that it may lead to more sharing of online coursework in Kansas teacher education programs in the future. 相似文献

El lenguaje verbal es nuestra red de carreteras, el sistema básico y central de la comunicación humana. No obstante, existen sujetos que no pueden acceder a él, como hay ciudadanos que no disponen de automóvil. El uso cada vez más generalizado en la educación y en el tratamiento de aquellas personas con déficits o alteraciones en sus posibilidades de comunicación de sistemas alternativos hace imprescindible conocer y evaluar estos sistemas. En este artículo se hace una revisión seria y a la vez guiada por los conocimientos de aplicación, de estos sistemas alternativos de comunicación. Sin embargo el interés de estos sistemas no puede limitarse a aquellos sujetos que no disponen del sistema normal, del mismo modo que el coche no se limita a los inválidos o la música a los ciegos. El conocimiento de los sistemas alternativos, aún cuando afecte más a personas con necesidades especiales, parece poder ser también una extensión natural para alumnos y profesores normales que desean ampliar extensiva, metacognitiva y humanamente su comunicación y su representación. 相似文献

Intelligent learning systems (ILSs) have evolved in the last few years basically because of influences received from multi-agent architectures (MAs). Conflict resolution among agents has been a very important problem for multi-agent systems, with specific features in the case of ILSs. The literature shows that ILSs with cognitive or pedagogical agents are prone to arbitration methods, where as ILSs with reactive agents are much in favor of control mechanisms. For these kind of systems, different control types are proposed based on the different stimuli that these agents will receive. These stimuli are aspects to be evaluated during the teaching/learning process such as: (1) error analysis, (2) learning styles, (3) analogies, (4) social aspects, etc. The paper reviews several ILSs, related to our work; different control mechanisms are proposed to solve the agents' intervention conflicts. Finally, the use of several mechanisms is exemplified by the results of a specific ILS. 相似文献

The aim of this paper is to analyze the effect of electoral timing on municipal public cultural spending. We use a panel sample of all municipalities from the Spanish Region of Murcia for 1995–2008. Our results reveal that mayors adopt an opportunistic behavior, increasing cultural spending in the election year and reducing it in the second year after the election. We also investigate whether the electoral cycle in cultural spending is influenced by mayors’ ideology, political strength, willingness to run for re-election, and electoral competitiveness. In this regard, our study shows that when mayors expect close elections, political budget cycles’ size is greater. Concerning political leadership, the magnitude of the electoral cycle is influenced by mayors’ political ideology rather than mayors’ political strength and re-election willingness. Additionally, we seek to shed some light on the determinants of public cultural spending. We find that income and upper-level governments’ transfers have a positive impact on cultural spending. Finally, unemployment, young people’s proportion and elderly people’s proportion negatively influence cultural spending. 相似文献

We describe the results of electromigration desalination of two soluble salt-contaminated Galician granites. The efficacy of electromigration, which had not been previously applied to granite, was assessed for two types of granite contaminated with a 20% NaCl solution and seawater. Desalination effectiveness was evaluated as follows: (1) analysis of anode and cathode ion content during testing; (2) analysis of ions at different distances from the electrodes after testing; (3) pH assessment of the stone surfaces; and (4) evaluation of colour changes. Results were very satisfactory; by the end of testing, chloride was reduced by almost 100% in both the NaCl and seawater contaminated samples. Sulfate reduction was also significant, despite this ion's lower mobility. The granite pH values remained close to neutral and colour changes were minimal. The difference in effectiveness of the process for the two types of stone was associated with their dissimilar pore structure. 相似文献

Vietnam is an important case for studying the impact of foreign firms’ backward linkages on local firms’ productivity. As an emerging economy Vietnam became the second most popular FDI destination after China in Pacific Asia since 2014. Our empirical analysis for Vietnam as a whole demonstrates a significant difference in the productivity growth between domestic suppliers who have a direct linkage with foreign firms and non-suppliers. This is also true for the Southeast Region (SE) with Ho-Chi-Minh City as economic center. However, in the Red River Delta (RRD), that difference is not statistically significant. Based on in-depth interviews with domestic suppliers, we reveal that in the RRD, effects of foreign firms on the productivity upgrading of domestic suppliers are indirect and limited while internal factors like absorptive capacity are more important for the productivity growth. These regional differences can be traced back to different regional specializations which still persist from the pre-reform era. 相似文献

Management literature has identified high-skilled human capital as a crucial dimension of innovation processes at the firm level. In this study, we introduce an alternative view of human capital based on the tasks that firms’ workers perform. We propose a measure of cognitive analytical and interpersonal tasks: the degree of abstractism. We argue that the level of abstractism of a firm has an effect on a firm's propensity to innovate and on its product innovation performance. We hypothesize that while the degree of abstractism has a linear positive relationship with the propensity to innovate, the relationship between abstractism and product innovation performance follows an inverted u-shaped relationship. We find partial support to our hypotheses using data from more than six thousand Portuguese firms. We discuss how these results change our understanding of the relationship between human capital and innovation at the firm level. 相似文献

ABSTRACT The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes. 相似文献
