Research Findings: In this research we explore the relationship between young children’s number knowledge and their measurement of length. First, we examined 4- to 5-year-olds’ (kindergartners’) understanding of and preference for using standard or nonstandard units to measure length. Second, we investigated whether the following tasks were related to children’s understanding of using standard (i.e., rulers) and nonstandard (i.e., blocks) units to measure length: (a) counting and written number identification knowledge, (b) symbolic or nonsymbolic number magnitude comparison ability, and (c) approximate number line estimation ability. Third, we examined whether understanding these number tasks predicted understanding how to measure length for both standard and nonstandard units. Our results show that young children prefer to use standard units of measurement when given a choice, and some of these children use a ruler correctly. Our results also show an important relationship between children’s understandings of numbers and measurement. Practice or Policy: Given children’s preference for rulers, introducing both nonstandard and standard units in early learning settings concurrently rather than consecutively is recommended for practice.  相似文献

Individual differences in children’s number knowledge arise early and are associated with variation in parents’ number talk. However, there exists little experimental evidence of a causal link between parent number talk and children’s number knowledge. Parent number talk was manipulated by creating picture books which parents were asked to read with their children every day for 4 weeks. N = 100 two- to four-year olds and their parents were randomly assigned to read either Small Number (1 – 3), Large Number (4 – 6), or Control (non-numerical) books. Small Number books were particularly effective in promoting number knowledge relative to the Control books. However, children who began the study further along in their number development also benefited from reading the Large Number Books with their parents.  相似文献

In human history, the origin of the numbers came from definite practical needs. Indeed, there is strong evidence that numbers were created before writing. The number “1”, dating back at least 20,000 years, was found as a counting symbol on a bone. The famous statement by the German mathematician Leopold Kronecker (1823–1891), “God made the integers; all else is the work of man,” has spawned a lively modern philosophical discussion, and this discussion begins by trying to get a philosophical handle on “1.” This approach remains under heavy discussion, and is more-or-less unresolved (Frege in Die Grundlagen der Arithmetik (English: The foundations of arithmetic). Polhman, 1884). In this note, we consider the many facets of “one” in it many guises and applications. Nonetheless, “one” has multiple meanings, from the very practical to the abstract, from mathematics to science to basically everything. We examine here a mere slice of mathematical history with a focus on the most basic and applicable concept therein. It troubles many, particularly students, even today.  相似文献

Research Findings: In this research, 487 Chinese children age 3 to 5 years took part in a number line estimation task. This task was used to assess children’s estimation accuracy and their estimation patterns along a number line in two different estimation circumstances. Situation A had the same line lengths for different numeric ranges, whereas situation B held the ratio of line lengths to numeric ranges constant. There were also three different number ranges (1–5/10/20). A new mathematical modeling method was proposed, where the two-dimensional estimation patterns of one child would be modeled as points in a higher dimensional space. Then the Dirichlet process Gaussian mixture model was applied to dynamically estimate the number of classes and assemble the different points into discrete classes based on distance. Three conclusions were drawn as follows: (a) significant differences were found within children for different ages and number ranges; (b) Chinese preschoolers had more estimation patterns than just linear pattern and logarithmic pattern, especially in small number ranges; and (c) mental number distance played an important role in their estimation patterns. Practice or Policy: Implications for early mathematic instruction on children’s understanding of mental number line are discussed.  相似文献

Research Findings: Teachers and parents often use trade books to introduce or reinforce mathematics concepts. To date, an analysis of the early numeracy content of trade books has not been conducted. Consequently, this study evaluated the properties of numbers and counting within trade books. We coded 160 trade books targeted at establishing early numeracy skill in children to determine the numbers included; the representations of number presented; and how books used representations of number to inform children about numbers, including counting. The main findings included limited opportunity to learn the number 0 and numbers beyond 10 as well as limited exposure to multiple representations of number deemed necessary to build strong number understanding and counting skills. Practice or Policy: We discuss practical implications for the selection and use of trade books about number with young children.  相似文献

Growing awareness of the importance of education in the early years has led professional organizations and policy makers to consider the effectiveness of mathematics education for young children. Factors such as educational environments, early years curricula and teacher education are some of the many aspects that have been examined. This paper describes the types of mathematical content knowledge that 25 prospective primary teachers developed as they designed, taught and reflected upon early number lessons. This Lesson Study approach involved two mathematics educators and 25 prospective primary teachers designing, teaching and re-teaching five early number lessons in two elementary classrooms with 4–5 year old children. The results suggest that effective teaching of early number concepts draws on mathematical knowledge that is specialized and unique to teachers; in other words Specialized Content Knowledge (SCK). The study found that engaging in Lesson Study promoted mathematics SCK development in two primary ways, notable by: (1) raising awareness of the complex relationships between early number concepts that contribute to developing robust early number understandings and (2) developing expertise in identifying the nature and source of children’s mathematical errors. The development of participants’ early number SCK is described and recommendations are made for the design of experiences in Initial Teacher Education (ITE) to support teachers in the provision of high quality mathematics experiences to young learners.  相似文献

Many counseling centers have session limits to accommodate the increasing number of clients who seek treatment. The current study explored clients' expectations for the number of sessions over the course of one year at a large university counseling center. In contrast to previous research that has suggested clients want ten or fewer sessions, our results suggest that over 60% of clients wanted 20 or more sessions. Moreover, clients who expected 20 or more sessions reported therapy was less effective than clients who expected less than 20 sessions. While actual number of sessions was related to expected number of sessions, termination status appeared to be related to clinical factors and not clients' expected number of sessions. Implications for clinical practice and agency session limit policies are discussed.  相似文献

The present study examined predictive power of behavioral self-regulation, family and child characteristics on children’s number sense. The participants consisted of 101 kindergarten children. A subsample of 30 children was randomly chosen for the reliability procedures of Assessing Number Sense and Head, Toes, Knees and Shoulders instruments. Thus, data from 71 children were used for further analysis. Multiple regressions using stepwise method were computed for determining whether self-regulation, family income, parents’ level of education, gender, and age related to and were predictive of scores on number sense. Results of the study indicated that behavioral self-regulation, mothers’ education level, gender and age are significant predictors of number sense, and behavioral self-regulation was the most influential predictor, followed by mothers’ education level, gender and age. Findings are discussed in terms of influential factors of number sense in early childhood.  相似文献
