大学英语分课型教学模式的反馈与评价

运用量化与质化相结合的方法调查了大学英语分课型教学模式,学习者对英语视听说课程的评价,并分析了不同年级、不同性别学习者对视听说课程的感知差异以及性别和年级之间的交互作用。研究结果显示:(1)学习者对视听说课程普遍比较满意;(2)高年级学习者对视听说课程的评价比低年级学习者更为正面;(3)女生在"语言应用能力"和"自主学习能力"两个维度上的得分高于男生;(4)性别和年龄的交互作用在"教学资源的使用效果"和"自主学习能力"两个维度的作用显著。研究结果表明,我们有必要继续实施并完善大学英语分课型教学模式,以进一步深化大学外语课程改革。     

Banach空间中单调算子的性质

设X为Banach空间,X~*是它的共轭空间,在X自反的情形下,关于X的子集D到X~*的单调算子成立锐角原理.本文对一般Banach空间X,考虑X~*的子集A到X的单调算子,不需要假设X及X~*自反,证明了单调算子的锐角原理,Minty-Browder定理及强单调映象原理.     

泰国学生汉语差比句习得的特点及偏误分析

文章对比了泰国学生中介语语料与汉语母语者语料中差比句的使用情况,分析了泰国学生差比句习得的特点和偏误类型。研究发现,泰国学生中介语语料与汉语母语者语料中各句式的使用频次不完全一致,使用频次与正确使用频率也不完全一致;泰国学生汉语差比句偏误率较高,偏误类型复杂多样,其主要原因在于汉泰语＂比/■＂字句在形式和功能意义上错综复杂的对应关系和对应＂空缺＂。文章最后提出了针对泰国学生汉语差比句的教学策略,确定了有＂泰国特色＂的差比句教学难度等级序列。

Development and field validation of an omni-domain power-duration model

ABSTRACT

Purpose: To validate and compare a novel model based on the critical power (CP) concept that describes the entire domain of maximal mean power (MMP) data from cyclists.

Methods: An omni-domain power-duration (OmPD) model was derived whereby the rate of W? expenditure is bound by maximum sprint power and the power at prolonged durations declines from CP log-linearly. The three-parameter CP (3CP) and exponential (Exp) models were likewise extended with the log-linear decay function (Om3CP and OmExp). Each model bounds W? using a different nonconstant function, W?eff (effective W?). Models were fit to MMP data from nine cyclists who also completed four time-trials (TTs).

Results: The OmPD and Om3CP residuals (4 ± 1%) were smaller than the OmExp residuals (6 ± 2%; P < 0.001). W?eff predicted by the OmPD model was stable between 120–1,800 s, whereas it varied for the Om3CP and OmExp models. TT prediction errors were not different between models (7 ± 5%, 8 ± 5%, 7 ± 6%; P = 0.914).

Conclusion: The OmPD offers similar or superior goodness-of-fit and better theoretical properties compared to the other models, such that it best extends the CP concept to short-sprint and prolonged-endurance performance.     

The Origin of Language and its Link with Music according to the Theory of Jābir ibn [Hdot]ayyān

Jābir ibn [Hdot]ayyān took advantage of the vast translation enterprise of Greek scientific works into Arabic. He quotes from these sources, including several whose Greek originals are lost. His works can be likened to the encyclopedia of Ikhwān al-[Sdot]afā’, the most important transmission of Pythagorean tradition. In this Epistle on Music the Ikhwān followed Jābir's method, and perhaps were influenced by him, in analysing the relationship between language and music, together with the arithmetical speculations that were widely influential. In this article, I have attempted to collect Jābir's scattered ideas on the origin of language and music trying to assemble the major ones in a coherent exposition.

艺术类专业学生职业信仰现状及改进途径--基于浙江艺术职业学院的职业观调研

职业信仰作为职业观中的核心内容,对于学生更好地认同核心价值、更快地明确职业志向、更有效的提升精神境界发挥着积极作用。目前,艺术类专业学生的职业观教育得到高度关注,但在对某艺术学院的职业观调研中我们也发现诸如职业认知清晰、职业情感凸显、职业责任偏弱、职业选择务实、职业规划盲目、专业差异显著等方面的现况,为此试图从心理机制、学校教育以及社会因素等方面探讨艺术类专业学生职业信仰教育的基本途径。
