独立学院英语专业翻译教学模式刍议——以翻译能力培养为中心

独立学院英语专业翻译教学的培养目标应凸显其应用性和实用性,在打好坚实语言基础的同时,还要注意培养学生的翻译能力。要获得和提高独立学院英语专业学生的翻译能力就需要在明确教学目标的前提下,制定适宜于学生自身特点的教学大纲,选择适宜该类学院翻译教学的内容与材料,有可能的话最好根据学生和地域实际情况编纂翻译教材,确定翻译课程教学方法,最后还要形成包括翻译能力测评、反馈体系等在内的评价机制。     

Flat-top and low-dispersion optical interleavers based on nested prism pair structure

A novel flat-top and low-dispersion optical interleaver using ring cavities (RCs) in a Mach-Zehnder interferometer (MZI) is proposed. It is composed of eight mirrors and two nested prism pairs. Each prism and the two mirrors behave as a RC. Phase shift of RC is a periodic function of the frequency of the input light which acts as a phase dispersive mirror. The two phase shifts needed to achieve a flat-top spectral passband are provided by Fresnel reffectivities at the prism-air interface of the two RCs. The...     

从社会成本与私人成本视角审视非公有制经济

非公有制经济的基本特征是私人成本较低,而社会成本较高。其私人成本较低,既是非公有制经济的生机活力的典型反映,也是它们基于自身的利益驱动将部分私人成本转嫁为社会成本的结果。社会成本较高,这是非公有制经济难以克服的根本缺陷。客观认识非公有制经济的成本高低和竞争优劣问题,应当从私人成本与社会成本相结合的视角,来审视非公有制经...

玩具数量对3～6岁幼儿分享行为的影响

为了用实验的方法探讨玩具数量对3～6岁幼儿分享行为的影响,选取了某幼儿园小、中、大班各30名幼儿,将各年龄班的幼儿随机分成人数相等的三组,三组进行游戏时玩具的数量不等,即分别为玩具数量多于、等于和少于小组人数。结果表明：小班、大班的幼儿都表现出当玩具数量少于人数时,幼儿做出分享行为的人数明显多于玩具数量等于和多于幼儿人数的情况。但中班幼儿面对不同数量玩具时的分享行为差异不显著。另外,当玩具数量等于人数时,表现出了明显的年级差异,大班幼儿做出分享行为的人数显著多于小班和中班幼儿。当玩具数量多于人数或少于人数时,不同年级幼儿的分享行为差异不显著。本研究的结论是：玩具数量是影响分享行为的因素之一,随着玩具数量的减少,幼儿的分享行为在增加。

Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.     

Learning Is Moving in New Ways: The Ecological Dynamics of Mathematics Education

Whereas emerging technologies, such as touchscreen tablets, are bringing sensorimotor interaction back into mathematics learning activities, existing educational theory is not geared to inform or analyze passages from action to concept. We present case studies of tutor–student behaviors in an embodied-interaction learning environment, the Mathematical Imagery Trainer. Drawing on ecological dynamics—a blend of dynamical-systems theory and ecological psychology—we explain and demonstrate that: (a) students develop sensorimotor schemes as solutions to interaction problems; (b) each scheme is oriented on an attentional anchor—a real or imagined object, area, or other aspect or behavior of the perceptual manifold that emerges to facilitate motor-action coordination; and (c) when symbolic artifacts are introduced into the arena, they may both mediate new affordances for students’ motor-action control and shift their discourse into explicit mathematical re-visualization of the environment. Symbolic artifacts are ontological hybrids evolving from things with which you act to things with which you think. Students engaged in embodied-interaction learning activities are first attracted to symbolic artifacts as prehensible environmental features optimizing their grip on the world, yet in the course of enacting the improved control routines, the artifacts become frames of reference for establishing and articulating quantitative systems known as mathematical reasoning.
