AbstractThis paper presents a case study of a first grade student to illustrate the diversity of her understandings related to variables and variable notation. While prior research has documented secondary school students’ difficulties with variables and variable notation, we identify many productive understandings in this much younger student, leading us to question the prevailing argument that students might have difficulties with variables due mostly to their own limitations. We draw our data from a teaching experiment that explored functional relationships. Individual interviews were carried out with a subset of the students in the experiment prior to, as well as mid-way through and at the end of the experiment. This paper focuses on a set of three interviews with one of the first grade students. We illustrate the shifts that occurred in the student’s understandings about variables and variable notation across as well as within each of the three interviews. 相似文献

In recent international and Australian early childhood curriculum guidelines and child-protection policies, the need for teachers of young children to foster spirituality has been highlighted. However, what this might mean in practice has not been widely explored. This article addresses the more controversial issue of spiritual abuse and the right of children to protection in terms of spiritual development. We present a critique of current definitions taken from research and policy documents. Qualitative data provide the research background. Vignettes are presented to give examples of what spiritual harm might look like in practice. Finally, a strengths-based approach is introduced and strategies are suggested in order to explore the potential of the Strengths Approach (a social justice approach originating from social service practice) to aid early years’ teachers to create spiritually protective learning environments. This approach recognises and values children’s holistic development and wellbeing and supports them to appreciate, engage with and question the world around them with a resilient spirit. 相似文献

In this 8‐year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty‐four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept‐slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high‐high (with a large initial vocabulary size and a fast growth rate), low‐high (with a small initial vocabulary size and a fast growth rate) and low‐low (with a small initial vocabulary size and a slow growth rate) groups. Low‐high and low‐low groups were distinguishable mostly through phonological skills, morphological skills and other reading‐related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language‐related and reading‐related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development. 相似文献

A new grouping principle, uniform connectedness (UC), has been posited to be a basic organizer of visual pattern information,
one that takes precedence over other, more classic grouping principles (Palmer & Rock, 1994), but its ontogenetic origins
have not previously been investigated. We examined whether 3- to 4-month-olds and 6- to 7-month-olds utilize UC to organize
static two-dimensional displays. Infants habituated to uniformly connected patterns exhibited a novelty preference for disconnected
element patterns, whereas those without any habituation failed to exhibit a preference. The results indicate that infants
are sensitive to UC as a cue for perceptual organization. Prior studies indicate that some Gestalt principles (e.g., common
movement) are functional during the first half year of life, but that other principles (e.g., form similarity) are less readily
available. The present finding showing that young infants are sensitive to UC points to the foundational nature of this cue
and adds to an emerging body of evidence indicating that at least some of the mechanisms believed to produce perceptual organization
in adults are already operational in the first months of life. nt]mis|This research was supported by grants from the National

Motor deficits are the most common outcome of brain damage. Although a large part of such disturbances arises from loss of elementary sensorimotor functions, several syndromes cannot be explained purely on these bases. In this article, we briefly describe higher-order motor impairments, with specific attention to the characteristic ability of the human hand to interact with objects and tools. Disruption of this motor skill at several independent levels is used to outline a comprehensive model, in which various current proposals for a modular organization of hand-object interactions can be integrated. In this model, cortical mechanisms related to object interaction are independent from representations of the semantic features of objects. 相似文献
