The reality of virtual worlds: pros and cons of their application to foreign language teaching

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).     

Comparing creative thinking abilities and reasoning ability of deaf and hearing children

This study focuses on comparing the creative thinking and reasoning abilities of deaf and hearing children. Two groups of deaf (N = 210) and hearing children (N = 200) were chosen based on specific criteria. Two instruments were used in the study: theTorrance Tests of Creative Thinking‐Figural, Form A and Matrix Analogous Test. Canonical Correlation analysis and multivariate analysis of variance (MANOVA) were used to analyze the data. The canonical correlation analyses revealed one significant dimension in both deaf and hearing children. The multivariate analysis of variance (MANOVA) revealed that there are some similarities and differences between the deaf and hearing samples regarding creative thinking abilities.

A review of research based on published research reports andunpublished M.Sc. and Ph.D. dissertations is presented and basic lines of researchare discussed. Special emphasis was placed upon culturally specific issues,besides the culturally determined attitudes of parents and teachers. The need for anationwide system for the prevention of violence and corporal punishment wasemphasized.     

艺术类高职高专英语ESP教学模式探讨

随着中外文化交流的日益频繁,艺术类高职高专英语教学肩负着培养具有英语文化交流能力特别是能运用英语进行艺术专业信息收集、传递、分析的人才。目前的英语教学模式重在帮助学生打好语言基础。ESP教学模式有效运用交际教学理念和实践,同时对现有的师资、教材教法也提出了更多的思考空间。文章通过对艺术类高职高专英语教学的关注,试图对ESP教学模式的实施进行探讨。     

大学生健美操创编能力的培养

健美操教学中,除了基本动作和理论知识外,教师更应注重学生创编能力的培养,这样才能不断提高教学质量,促进健美操运动的发展。     

高职院校校企文化融合能力建设的研究

校企文化融合是校企深度合作的重要标志和迫切要求,对高职人才培养质量提升具有积极作用。文化融合也是校企深度合作的关键,它不仅需要从校企双方愿景、合作内容、载体和模式上解读文化融合的可能,更应该站在文化生成的自身立场进行观照。校园文化与企业文化具有不同的内涵、价值、优势和劣势,既有差异性也有共同点,实现校企文化融合意味着两种文化碰撞、冲突,相互吸收、融通互补,最终形成具有融合性、超越性和创新性的新文化类型。高职院校应该从文化意识、文化批判和文化建设三个维度,提升自身能力,推进校企文化融合,实现校企深度合作。     

企业认知偏差与产能过剩

摘要：在工业周期性运行过程中,常会出现产能过剩、产能不足两个极点状况。特别对于我国正处于向市场经济转轨过程中,产能过剩问题屡屡出现,给经济发展和经济效率带来了严重影响。但是在传统经济学理论中,企业及市场是完全理性的,通过价格机制作用和市场出清,不会出现严重的产能过剩或产能不足。本文认为,作为微观主体的企业,在投资决策过程中并非全知全能、完全理性的,存在着有限理性行为。文中利用双曲线贴现模型,将认知偏差理论引入到产能过剩问题的研究中来,从微观视角分析了企业作为市场中的微观主体的投资行为,得出结论：由于存在认知偏差系数β,企业会在经济过热时出现冲动投资,在经济处于低谷时拖延投资,导致产能与市场需求的非同步变化,最终形成产能过剩、产能不足。本文还根据模型得出的调节系数β及c,提出针对产能过剩问题的调控政策建议,即通过惩罚和补贴等措施,引导企业投资行为,减弱企业认知偏差,减缓工业周期性波动幅度,实现经济平稳健康发展。     

Professional development to increase teacher behavior‐specific praise: A single‐case design replication

Effective classroom instruction is contingent upon successful classroom management. Unfortunately, not all teachers successfully manage classroom behavior and need in‐service professional development. In this study, we replicated a targeted professional development approach that included a brief one‐on‐one training session and emailed visual performance feedback to increase novice teachers’ use of behavior‐specific praise, an evidence‐based classroom management skill. Dependent variables collected through direct observation included teachers’ behavior‐specific praise along with average student engagement and disruptions. Four elementary teachers participated and, based on a multiple‐baseline single‐case design, we found a functional relationship between the targeted professional development and teachers’ increased use of behavior‐specific praise. However, because of variability and one teacher's limited response, effect sizes were small for behavior‐specific praise and little change was observed in student behaviors. These findings warrant further research to determine which classroom management skills affect student behaviors overall, as well as continued evaluation of this professional development model and using school‐based coaches.     

拳击比赛与4种专项训练后的乳酸和脉搏值变化的分析

跟踪监测了优秀拳击运动员比赛和4种不同负荷方式训练后的乳酸(LA)值和脉搏(HR)值。结果显示，比赛后的LA值高于4种不同负荷方式训练后的LA值；4种不同负荷方式训练后的LA值也存在明显差别；4种不同负荷方式训练后的HR值无明显差别。拳击运动员4种不同负荷方式训练后的LA测试结果显示，疾跑练习无氧酵解强度最高。
