The acquisition of early mathematical knowledge is critical for successful long-term academic development. Mathematical language is one of the strongest predictors of children's early mathematical success. Findings from previous studies have provided correlational evidence supporting the importance of mathematical language to the development of children's mathematics skills, but there is limited causal evidence supporting this link. To address this research gap, 47 Head Start children were randomly assigned to a mathematical language intervention group or a business-as-usual group. Over the course of eight weeks, interventionists implemented a dialogic reading intervention focused on quantitative and spatial mathematical language. At posttest, students in the intervention group significantly outperformed the students in the comparison group not only on a mathematical language assessment, but on a mathematical knowledge assessment as well. These findings indicate that increasing children's exposure to mathematical language can positively affect their general mathematics skills. This study is an important first step in providing causal evidence of the importance of early mathematical language for children's general mathematical knowledge and the potential for mathematical language interventions to increase children's overall mathematics abilities. 相似文献

Recent research has found that linguistic cues may affect children's number word acquisition. Two studies were undertaken to evaluate the use of singular/plural markings and small number words in Chinese and English and its effect on children's number concepts. The first study utilized the CHILDES data and investigated how singular/plural markings and number words of "one," "two," and "three" are used in Chinese and compared it with that of English. The second study entailed testing twenty-four 2.4- to 3.3-year-old Chinese- and English-speaking children on number identification tasks. Results show that the English-speaking children performed significantly better than Chinese-speaking children in identifying "two," "three," and "four" as referents for collections of multiple items but not in identifying those number words as referents for specific pluralities. Additionally, the results show that English-speaking children were more inclined to count when quantifying small number sets than Chinese-speaking children. 相似文献

Over two decades ago, the “30-million-word” gap rose to prominence after work by Hart & Risley (1995) suggested that children from families with low socioeconomic status (SES) heard fewer words than their peers from families with higher SES during their first 4 years of life. Recent research challenges the magnitude and even existence of this gap. However, due to methodological limitations, we know very little about the presence, magnitude, and settings in which there may be a word gap. Moreover, causal evidence is also limited. I highlight why it is critical for the field to have a more precise understanding of the nature of the word gap (or lack thereof) and potential avenues for better evaluating this phenomenon. 相似文献

Research Findings: The focus of this study was to construct and validate 12 brief early numeracy assessment tasks that measure the skills and concepts identified as key to early mathematics development by the National Council of Teachers of Mathematics (2006) and the National Mathematics Advisory Panel (2008)—as well as critical developmental precursors to later mathematics skills noted in the Common Core State Standards (2010). Participants were 393 preschool children ages 3 to 5 years old. Measure development and validation occurred through 3 analytic phases designed to ensure that the measures were brief, reliable, and valid. These measures were 1-to-1 counting, cardinality, counting subsets, subitizing, number comparison, set comparison, number order, numeral identification, set-to-numerals, story problems, number combinations, and verbal counting. Practice or Policy: Teachers have extensive demands on their time, yet they are tasked with ensuring that all students’ academic needs are met. To identify individual instructional needs and measure progress, they need to be able to efficiently assess children’s numeracy skills. The measures developed in this study not only are reliable and exhibit evidence of validity but also are easy to use and can be utilized for measuring the effects of targeted instruction on individual numeracy skills. 相似文献

Preschool-aged children (n = 58) were randomly assigned to receive small group instruction in letter names and/or sounds or numbers (treated control).
Alphabet instruction followed one of two approaches currently utilized in early childhood classrooms: combined letter name
and sound instruction or letter sound only instruction. Thirty-four 15 minute lessons were provided, with children pre- and
post-tested on alphabet, phonological awareness, letter–word identification, emergent reading, and developmental spelling
measures. Results suggest benefits of combined letter name and sound instruction in promoting children’s letter sound acquisition.
Benefits did not generalize to other emergent literacy skills. 相似文献
