EFL teachers’ perceptions of English language policy at the elementary level in Taiwan

Due in large part to the trends towards economic globalization, English has become the most widely disseminated and ubiquitous international language. The purpose of the study was to investigate what Taiwan’s EFL teachers at the elementary level believe about the policy of English as a compulsory subject and how they perceive the benefits and obstacles of the policy’s implementation. Ten elementary English teachers in Tainan City and its suburban areas participated in this study. Data were collected through teachers’ interviews, classroom observation and document analysis. Results found that all ten teachers agreed with the policy for English as a compulsory subject at the elementary level. They observed both positive and negative sides of this top‐down policy. Classroom observation and interview data revealed that EFL teachers had to plan their English classes with the constraints on a large class of students with mixed levels of proficiency, limited teaching hours and resources. Parents’ expectations of and attitudes towards English learning also became an obstacle.     

Regarding uncertainty in teachers and teaching

The literature on teacher uncertainty suggests that it is a significant and perhaps inherent feature of teaching. Yet there is disagreement about the effects of these uncertainties on teachers as well as about the ways that teachers should regard them. Recognition of uncertainties can be viewed alternatively as a liability or an asset to effective teaching. Findings from the literature on uncertainties in teaching are summarized and analyzed, including explanations in the research about what accounts for and contributes to uncertainties. Recommendations for research and professional development are provided.     

社会转型·社会治理·社会回应机制链

在全球化多元共生、开放、回应与同构的趋势中，中国社会转型与西方社会转型因社会主义制度因素的嵌入而具有非同源性，但中国因工业化、现代化的使然，仍引发了社会结构的重构和具有现代性特质的社会分化开始，并凸显出我国传统的政府与社会高度合一管制模式的内生性冲突。因而在社会转型情境中建设和谐社会，不仅需要重设动力机制、社会机制，而且建设和谐社会的新制度安排还需要建立一套不断完善的社会机制链才能持续地转化为现实生产力，才能促进与实现社会的和谐。     

一类两种群食饵-捕食者模型的定性分析

具功能性反应的两种群食饵-捕食者模型：＆=xg（x）-yφ（x）,＆=y（-d＋eφ（x））当食饵种群的相对增长率g（x）与捕食者种群的捕食率φ（x）都是非线性的情况,运用微分方程稳定性理论和Poincaré-Bend ixon环域定理,探讨了系统平衡点的稳定性,给出系统极限环存在的充分条件.     

单盘转子不平衡的瞬态动力响应分析

转子的不平衡是引起转子失稳的主要因素,对机器有着不利的作用;不平衡的响应特性是一个值得关心的问题。本文建立了单盘转子的运动微分方程,分析了在各个加速度条件下的响应特性,研究表明,不同加速度的不平衡瞬态响应有一定的规律,加速度越大,响应越小,相位越小;同时进动角速度可以分为三个区域波动。这些特性对于转子平衡有一定的指导作用。     

Screening of phonological awareness in the early elementary grades: an IRT approach

The purpose of the present study was to explore the possibilities for the assessment of growth in phonological awareness of children in kindergarten and first grade. Phonological awareness was measured using four sets of items involving rhyming, phoneme identification, phoneme blending, and phoneme segmentation. The results of an exploratory factor analysis and analyses conducted within the framework of item response theory showed one latent ability to underlie the different sets of items, which nevertheless differed in difficulty. Analyses in terms of the children’s ability further showed the phonological awareness measures to be sensitive to growth. The amount of information supplied by the different sets of items depended on the children’s level of ability. The conclusion that it is possible to accurately monitor the development of children’s phonological awareness in the early elementary grades appears to be justified, and this possibility opens up new perspectives for the early screening for reading problems and dyslexia.     

论美国文化应答式教育的涵义与启示

文化应答式教育是利用学生的语言文化背景进行教学,促进学生在学业上获得成功的一种教育模式,主要针对少数民族学生的教育。我国的教育研究在这个方面尚处于起始阶段。借鉴美国的教育模式对我国这样一个多民族国家的教育有着极其重大的指导意义。     

校长领导权力合法性危机的反思与超越

校长领导权力合法性危机是指校长领导权力失去正当性且未获得被领导者的认同、支持和服从,其实质上是一种认同危机,主要表现为公共性危机、程序性危机、价值性危机及有效性危机等。通过注重公共意志及公共利益价值取向的联结、遵循程序正义与实质正义原则的统一、实现以人为本与交往伦理的结合及处理好适当集权与合理分权的协调等范式,可以缓解校长领导权力的合法性危机,最终实现学校的有效发展。     

基于VAR模型通货膨胀影响因素的实证分析

分析了十年我国两次比较严重的通货膨胀的成因,使用2001年1月—2010年9月的季度数据,在构建稳定的VAR模型基础上,通过建立协整方程,运用格兰杰因果检验以及脉冲响应函数的方法,对其进行分析。结果表明：经济增长、广义货币供给量、房地产销售价格指数、外汇储备与CPI之间存在长期的协整关系;长期内以房地产为代表的资产价格对CPI的冲击较大,短期内外汇储备推高CPI的效果最为显著。
