强化应用数学意识,提高数学应用能力

数学是一门应用的艺术,运用数学知识解决实际问题是我们学数学的重要目的之一。数学教学的关键是教会学生用所学的知识解决实际问题,即要提高学生的应用知识的能力,而目前,大部分学生应用意识薄,应用能力弱。长此以往,必将学而无用,适应不了社会发展的需要。因此培养学生的数学应用意识,提高学生应用数学知识解决问题的能力,在数学教育中尤为重要。本文作者阐述了两个方面的内容：一是强化应用数学意识;二是提高数学应用能力。     

法国教师教育的改革现状及其借鉴

法国于1989年着手立法并全面革新师资培养的体制,以推动中小学教师合流及师资培育管道多元化的新制。教师培训学院（les instituts universitaires de formation des maltres,简称IUFM）于1991年诞生。随着教师培训学院的建立,到2005年提出将教师培训学院并入大学,再到2010年末起正式推动实施教师资格硕士化方案,这20年来法国教师教育经历了一场制度上和教育上的变革。     

城市农民工就业培训问题实证研究——基于对江苏省常州市302位农民工的调查与分析

根据302份调查问卷数据,具体分析农民工入城就业情况与参与技术培训情况,结果显示,城市农民工就业情况堪忧,参与职业技术培训比率低,效果差。他们期待由政府和企业承担培训费用,渴盼以短期、休息时间为主,采取在职学习和现场学习等教学模式,期望除了就业单位培训外,还对政府行为寄予厚望。因此,有关部门应完善农民工就业促进机制,建立农民工职业技术培训长效机制。     

现代汉语二合复句中分句语气异类组配的倾向性研究

现代汉语二合复句内分句语气同类组配是主体,异类组配是次要的。前后分句语气异类组配的使用频率具有一定的倾向性：陈述与疑问／祈使／感叹的组配〉疑问／祈使／感叹之间的两两组配;陈述＋疑问／祈使／感叹〉疑问／祈使／感叹＋陈述。陈述语气与疑问／祈使／感叹共享特征的数量都多于疑问、祈使、感叹两两语气之间共享特征的数量,因此前者是优势组配。疑问／祈使／感叹居前时通常要满足三个条件,居后时不受此限制,因此疑问／祈使／感叹居后是优势组配。     

Equatorial aurora: the aurora-like airglow in the negative magnetic anomaly

The most fantastic optical phenomena in the Earth''s upper atmosphere are the auroras. They are highly informative indicators of solar activity, geomagnetic activity, upper atmospheric structures and dynamics, and magnetospheric energetic particles. An area where the geomagnetic field differs significantly from the expected symmetric dipole, such as at the South Atlantic Anomaly, where the magnetic field intensity is low, gives rise to stronger precipitation of energetic particles into the upper atmosphere. Impact excitation and the subsequent airglow emissions exhibit aurora-like dynamic signatures. Nomenclatures of nonpolar aurora or equatorial auroras are similar to those used with the polar auroras owing to their similar excitation mechanisms. This paper provides an overview of the knowledge and the challenges concerning auroral activity at the South Atlantic Anomaly, or more generally, at the negative magnetic anomaly. We emphasize systematic investigation of the equatorial auroras to reveal the temporal and spatial evolution of the magnetic anomaly and the behaviour of energetic particles in near-Earth space.     

Item analyses of the concept assessment kit-conservation for educable mentally retarded children

A series of item analyses of the CAK-C was conducted for a sample of 155 educable mentally retarded children. The probability of a correct response was found to differ from task to task, and there was evidence that the order of difficulty of the tasks for this sample resembled that for nonretarded children. The probabilities of the two incorrect responses were generally not equal, and the choice of one or the other incorrect response showed some relation to CA, MA, and IQ, particularly the last two variables.     

Interpreting the differences: A reply to Kaufman

Kaufman's critique of our article was based on a misunderstanding of our purpose and procedures. This reply clarifies those points and suggests further areas of concern regarding the McCarthy Screening Test.

Correlates of the concept assessment kit-conservation for educable mentally retarded children

The relations of the CAK-C to the Stanford-Binet and the WRAT were explored for a sample of 155 educable mentally retarded children. Correlational analyses indicated that: (a) The CAK-C is more closely related to MA than to either CA or IQ. (b) Both Reading and Arithmetic are more closely related to MA than to the CAK-C. The results support the position that Piagetian intelligence is somewhat distinct from psychometric intelligence, but suggest that the latter is the better predictor of academic achievement.
