Developmental cognitive neuroscience highlights the importance of interactions between children and their environment. As young children spend increasing time in childcare, it is key to investigate the impact of “maths‐talk” and maths provisions in preschools. Qualitative insights from early educators indicate a greater bias toward counting activities than would be expected given the Early Years curriculum. In addition, we quantified the observed breadth of preschool practitioners' maths language (e.g., place‐value language), setting‐based maths provisions (e.g., quality of maths‐related activities), and their relation with children's early numeracy skills. In settings with greater practitioners' breadth of maths language, children display greater cardinality skills although our data call for the further investigation of parental socioeconomic status and education. We conclude with a discussion on the need to operationalize children's maths learning environments as diversely as possible. Enriching practitioners' skill sets may be an effective and needed way of improving early maths outcomes. 相似文献

In human movement and sports science, manipulations of perception and action are common and often comprise the control of events, such as opening or closing liquid crystal goggles. Most of these events are externally controlled, independent of the actions of the participants. Less common, although sometimes desirable, are event manipulations that are dependent on the unconstrained movements of participants. As an example, we describe a method we used previously to manipulate vision of basketball jump shooters on the basis of on-line registration of their own movements. The shooters wore liquid crystal goggles that opened or shut as a function of specific kinematic features of these movements. The novel aspect of this method is that the criteria for detecting movement patterns and performing the appropriate manipulations are adjustable to the specific sport context and the complexity and variations of the unconstrained movements. The method was implemented as a finite state machine: a computer system that can be used for pattern recognition. We discuss this method, how it works and the potential it has for studying perceptual-motor skills in sport. Furthermore, the results of the basketball experiment are briefly summarized and complemented with new analyses. 相似文献

美国历史上最富传奇色彩的事件是加利福尼亚淘金潮。1948年在Sutter’sHill发现开会后不久，有4万多个淘金者手持工具涌向加利福尼亚寻找财富。不幸的是他们当中很少人迅速致富，而许多声称“找到了金子”的人，他们的发现最终被证明只是灿烂的石头或愚人金。从很多意义上来讲，互联网（WorldWideWeb）是1997年的淘金热潮。许多公司纷纷创立网页，进入国际互联网，意欲迅速致富。在网页中有没有金子？还是你将财力物力花在网页设计上，却发现一大堆的愚人金呢？很少国际互联网企业迅速致富，例外的只有一些将国际互联网用作直接销售渠道的… 相似文献
