The present study examined how the home literacy and numeracy environment in kindergarten influences reading and math acquisition in grade 1. Eighty-two Greek children from mainly middle socioeconomic backgrounds were followed from kindergarten to grade 1 and were assessed on measures of nonverbal intelligence, emergent literacy skills, early math concepts, verbal counting, reading, and math fluency. The parents of the children also responded to a questionnaire regarding the frequency of home literacy and numeracy activities. The results of path analyses indicated that parents’ teaching of literacy skills predicted reading fluency through the effects of letter knowledge and phonological awareness. Storybook exposure predicted reading fluency through the effects of vocabulary on phonological awareness. Finally, parents’ teaching of numeracy skills predicted math fluency through the effects of verbal counting. These findings suggest that both the home literacy and the home numeracy environments are important for early reading and math acquisition, but their effects are mediated by emergent literacy and numeracy skills.  相似文献

Cognitive correlates of math skills in third-grade students   总被引：1，自引：1，他引：0  
Math achievement is not a unidimensional construct but includes different skills that require different cognitive abilities. The focus of this study was to examine associations between a number of cognitive abilities and three domains of math skills (knowing, applying and problem solving) simultaneously in a multivariate framework. Participants were 723 third-grade children (mean age?=?9.07) from 28 elementary schools. Confirmatory factor analyses with binary indicators showed that a four-factor model of math skills (Knowing-Recalling, Knowing-Computing, Applying and Problem Solving) and a nine-factor model of cognitive abilities (Nonverbal and Verbal Reasoning, Verbal Concepts, Planning, Visuo-Spatial Working Memory (WM), two types of Verbal WM, Phonological Awareness and Phonological WM) fit the data well. Results from structural equation modelling showed that verbal reasoning and verbal concepts were most consistently associated with math knowing and problem solving domains. Verbal concepts contributed also to the math applying domain. In addition, simultaneous processing of verbal WM predicted problem solving skills in math. The results can be used in supporting the learning process of students with difficulties in math.  相似文献

In typical development, emergent literacy skills predict successful reading abilities. Code‐related literacy skills may include letter knowledge, print concepts, early writing and early phonological awareness. Meaning‐related literacy skills may include lexical and grammatical ability, story retelling and comprehension. Children with ASD (autism spectrum disorder) show, on the most part, poor reading comprehension abilities, yet up to date, research regarding emergent literacy skills in ASD is limited. We conducted a study to investigate a naturalistic, standards‐based national literacy programme, for five kindergartners with ASD, of age 5‐8 years in their kindergarten setting. We implemented an ASD‐adapted intervention as an intensive group treatment over 6 weeks, with a pretest–posttest design to examine emergent literacy gains. The children with ASD demonstrated gains in both code‐related and meaning‐related skills following intervention. The clinical and theoretical implications are discussed regarding the importance of an intensive structured literacy intervention for children with ASD before entering school.  相似文献

This paper reports on four studies that were all concerned with cognitive and non‐cognitive correlates of proofreading (PR) ability. A new, five‐minute PR test was devised and piloted. In the first pilot study (N = 191) it was correlated with a verbal reasoning test. In the second study (N = 103) PR scores were regressed onto measures of personality: approach to learning, general and fluid intelligence (verbal reasoning) as well as a test of general knowledge. All three cognitive ability measures were significant predictors of PR but when entered together, general knowledge alone remained significant and accounted for a third of the variance. The third study (N = 95) was similar, except it also included a measure of typical intellectual engagement. Fluid intelligence (verbal reasoning) and openness were the only significant predictors of PR. In the fourth study (N = 249) participants completed four tests: PR, fluid intelligence (verbal reasoning), vocabulary and spelling. PR was consistently correlated with verbal reasoning but more strongly correlated with measures of crystallised intelligence, namely general knowledge and vocabulary. Implications and limitations are considered.  相似文献

The primary goal of this study was the broad assessment and modeling of scientific reasoning in elementary school age. One hundred fifty-five fourth graders were tested on 20 recently developed paper-and-pencil items tapping four different components of scientific reasoning (understanding the nature of science, understanding theories, designing experiments, and interpreting data). As confirmed by Rasch analyses, the scientific reasoning items formed a reliable scale. Model comparisons differentiated scientific reasoning as a separate construct from measures of intelligence and reading skills and revealed discriminant validity. Furthermore, we explored the relationship between scientific reasoning and the postulated prerequisites inhibitory control, spatial abilities and problem-solving skills. As shown by correlation and regression analyses, beside general cognitive abilities (intelligence, reading skills) problem-solving skills and spatial abilities predicted performance in scientific reasoning items and thus contributed to explaining individual differences in elementary school children's scientific reasoning competencies.  相似文献

Intra‐individual variability of cognitive measures, such as verbal and spatial ability tests, has frequently been reported to typify learning disabled children. To test the generality of such findings, longitudinal data from a large representative and non‐clinical sample of Swedish children (n = 812) were analysed. At age 10, the children were tested with a Swedish intelligence scale. At age 13, basic academic skills were measured by standardised achievement tests. Typical cognitive profile types, based on the verbal and spatial intelligence subtests, were identified through cluster analyses (CLUSTAN) of the girl and boy samples separately. The satisfactory solution arrived at was a five‐cluster representation for the girls (n = 497) and an eight‐cluster representation for the boys (n = 497). For both sexes, verbally as well as spatially oriented profiles emerged. However, the verbal orientation was more pronounced for girls, whereas the boys displayed greater variability and stronger spatial orientation. General intelligence at age 10 was a strong predictor for basic skills at age 13 (r > 0.70). Verbally strong children tended to achieve better than predicted by their overall level of intelligence, whereas spatially oriented children showed a less favourable development in basic academic skills. The results are discussed in relation to neuropsychologically‐based models of reading disability and theories of language and development.  相似文献

Using a sample of 171 children, we examined classroom quality as a potential moderator of the link between three distinct but related aspects of cognition (fluid intelligence, crystallized intelligence, and executive functioning) and math achievement across the kindergarten year. Multilevel modeling analyses were conducted to account for nesting of students within classrooms. Results revealed significant aptitude by treatment interactions for fluid and crystallized intelligence, suggesting that classroom practices may affect children differently depending on their abilities. Children with higher levels of fluid intelligence and of crystallized intelligence fared better in higher quality classrooms. Results also provide some support for Cattell's investment hypothesis. Implications of the results are discussed.  相似文献

We examine the extent to which executive functions (EFs), as opposed to other cognitive skills, account for socioeconomically based disparities in school readiness. Participants are 226 American children (aged 36–71 months) enrolled in either needs-based or private preschools. Children completed 6 tasks designed to measure EFs as well as assessments of general intelligence and speed of cognitive processing. Children were also assessed on math, reading, and vocabulary skills. EFs accounted for unique variance across all academic measures even when controlling for speed of processing and general intelligence and partially accounted for disparities in school readiness associated with type of preschool enrollment. When vocabulary was controlled in the model, EFs only mediated associations between type of preschool and math. Vocabulary skills accounted for associations between socioeconomic status and both math and reading achievement. General intelligence and speed of processing did not uniquely account for associations between disadvantage and school readiness.  相似文献

This study investigated the role of broad cognitive processes in the development of mathematics skills among children and adolescents. Four hundred and forty-seven students (age mean [M] = 10.23 years, 73% boys and 27% girls) from an elementary school district in the US southwest participated. Structural equation modelling tests indicated that calculation complexity was predicted by long-term retrieval and working memory; calculation fluency was predicted by perceptual processing speed, phonetic coding, and visual processing; problem solving was predicted by fluid reasoning, crystallised knowledge, working memory, and perceptual processing speed. Younger students’ problem solving skills were more strongly associated with fluid reasoning skills, relative to older students. Conversely, older students’ problem solving skills were more strongly associated with crystallised knowledge skills, relative to younger students. Findings are consistent with the theoretical suggestion that broad cognitive processes play specific roles in the development of mathematical skills among children and adolescents. Implications for educational psychologists are discussed.  相似文献

Writing is a complex academic task—it involves numerous mental processes. Given the necessity for developing writing skills from elementary to secondary school, this study aimed to investigate the role of broad cognitive abilities derived from the Cattell–Horn–Carroll (CHC) theory of intelligence in predicting skills associated with writing achievement. The normative sample from the fourth edition of the Woodcock–Johnson Tests of Cognitive Abilities and the Woodcock–Johnson Tests Academic Achievement were used to examine the relationships between broad CHC abilities and academic achievement in writing. The findings of this study suggest that the broad CHC abilities Comprehension‐Knowledge, Processing Speed, and Fluid Reasoning are especially important predictors of basic writing skills and written expression during the school‐age years. In general, changes in the strength of the association between cognitive abilities and academic achievement in writing are observed over time, as the cognitive demands involved in the writing increase in complexity in later grades.  相似文献

Individual differences in academic success were investigated in a geographically defined whole-population sample of very preterm children with a gestational age of less than 32 weeks or a birth weight of less than 1500 gm. The sample consisted of 264 very preterm children (75.6% of German-speaking survivors) and 264 controls matched for gender, socioeconomic status, marital status and age of mother, who were studied from birth. The present analyses focused on the impact of cognitive skills assessed at ages 6 and 8 on academic success at the age 13. IQ scores, prereading skills, reading, spelling, and math performance assessed during the last kindergarten year and again at the end of Grade 2 were used as predictors of academic success in early adolescence. Differences between very pretern children and controls in cognitive abilities already observed in earlier assessments remained stable over time, with controls on average performing more than half a standard deviation above the level of preterm children. Preterm children also performed poorer on the literacy measures and indicators of math performance. Multivariate and causal modeling revealed different prediction patterns for the two groups. Whereas IQ was particularly important for the prediction of academic success in the pre-term sample, general IQ was less relevant for the prediction of academic success in the control group. When subgroups of at-risk children were formed according to birth weight categories, we found that school problems were most pronounced for children with extremely low birth weight (1000 gm and less).  相似文献

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition.  相似文献

With age, children employ increasingly more sophisticated strategies to solve single-digit addition (SDA) number fact problems. Changes in SDA strategy-use are correlated with age-related changes in cognitive measures (e.g., working-memory capacity, WM); however, this correlation does not explain the basis of SDA strategy-use or change per se. Does strategy-use reflect differences in generally reasoning abilities or are they uniquely tied to SDA abilities? Answers to these questions would help clarify the nature of SDA abilities specifically and early math abilities more generally. To investigate these issues, we assessed 144 5- to 9-year-olds' SDA strategies, visuospatial working memory (VSWM), verbal WM, non-verbal IQ, basic RT, and visuospatial reasoning abilities. We focused on these abilities since recent research shows visuospatial processes support early math development. We used latent profile/class analysis to classify children's SDA strategies and visuospatial reasoning abilities, which yielded four ability subgroups in both cases, only partially related to age. Findings show SDA strategy subgroup and general reasoning subgroup memberships were related. More sophisticated subgroups had better WM, but did not differ in IQ and RT. Findings suggest SDA reasoning reflect general reasoning abilities. Implications for math skills acquisition and intervention are discussed.  相似文献

We measured age and gender differences in children’s awareness and endorsement of gender stereotypes about math, science, and verbal abilities in 463 fourth, sixth, and eighth graders. Children reported their perceptions of adults’ beliefs and their own stereotypes about gender differences in academic abilities. Consistent with study hypotheses, fourth and sixth graders had a stronger tendency than eighth graders to favor their own gender group rather than report traditional stereotypes. On average, girls favored girls over boys in all three domains. Fourth grade boys favored boys in all three domains; middle school boys reported traditional verbal stereotypes and were on average egalitarian in beliefs about math and science. Children’s reports of their perceptions of adults’ stereotypes mirrored age and gender differences in their own stereotypes and were correlated with their own stereotype endorsement. In addition to showing beliefs favoring girls in verbal domains and a tendency for most age and gender groups to not endorse traditional math and science stereotypes, the results support a synthesis of developmental and social identity theories regarding individual differences in children’s stereotype endorsement. Children’s tendency to favor girls in verbal domains may contribute to gender differences in educational and career choices by pulling girls toward the humanities and social sciences and discouraging boys from pursuing those domains.  相似文献

This study examined the role of self-regulation in emerging academic ability in one hundred and forty-one 3- to 5-year-old children from low-income homes. Measures of effortful control, false belief understanding, and the inhibitory control and attention-shifting aspects of executive function in preschool were related to measures of math and literacy ability in kindergarten. Results indicated that the various aspects of child self-regulation accounted for unique variance in the academic outcomes independent of general intelligence and that the inhibitory control aspect of executive function was a prominent correlate of both early math and reading ability. Findings suggest that curricula designed to improve self-regulation skills as well as enhance early academic abilities may be most effective in helping children succeed in school.  相似文献

Age versus schooling effects on intelligence development   总被引：1，自引：0，他引：1  
S Cahan  N Cohen 《Child development》1989,60(5):1239-1249
The effect of formal education, as opposed to chronological age, on intelligence development has suffered from inadequate empirical investigation. Most studies of this issue have relied on natural variation in exposure to school among children of the same age, thus confounding differences in schooling with differences in other intelligence-related variables. This difficulty can be overcome by a quasi-experimental paradigm involving comparison between children who differ in both chronological age and schooling. The present study applies this paradigm to the estimation of the independent effects of age and schooling in grades 5 and 6 on raw scores obtained on a variety of general ability tests. The sample included all students in Jerusalem's Hebrew-language, state-controlled elementary schools. The results unambiguously point to schooling as the major factor underlying the increase of intelligence test scores as a function of age and to the larger effect schooling has on verbal than nonverbal tests. These results contribute to our understanding of the causal model underlying intelligence development and call for reconsideration of the conceptual basis underlying the definition of deviation-IQ scores. Some implications of these results concerning the distinction between intelligence and scholastic achievement, the causal model underlying the development of "crystallized" and "fluid" abilities, and the notion of "culture-fair" tests are discussed.  相似文献

The aim of this study was to identify the specific contribution of executive functions to pre-academic skills (emergent literacy, phonological awareness and orthographic knowledge, and emergent mathematic knowledge) over and above cognitive and linguistic underpinning abilities such as naming, short-term memory and vocabulary. The study was designed to examine the following questions: (1) Are executive functions related to pre-academics skills in general or are they related to specific pre-academic skills? (2) Does the magnitude of the relationship between executive functions and pre-academics skills change with the progress in pre-school age? 54 children between the ages of 5 and 6 years old from 4 different kindergartens participated in the project. A wide range of pre-academic skills, cognitive, linguistic and executive functions tasks were administered. The results demonstrated that executive functions contributed significantly to both emergent literacy and emergent mathematic knowledge. In addition, the current study also suggests that the role of executive functions increases with the growth of child’s pre-academic development. Finally, the strongest contribution of executive functions was found to orthographic knowledge.  相似文献

This paper reports on a longitudinal study using the computer‐based cognitive assessment system CoPS, and considers the applicability of this system in the early identification of cognitive strengths and limitations that affect the development of reading. CoPS comprises eight tests of basic cognitive abilities, including phonological awareness, auditory discrimination, and short‐term visual and auditory‐verbal memory. A total of 421 children participated in the study. Assessment with the CoPS tests was carried out at age 5 years, and follow‐up assessments using conventional tests of reading and general ability were carried out at 6 and 8 years of age. Correlations between the CoPS tests administered at age 5 and reading ability at age 8 were in the region of 0.6 for auditory‐verbal memory and phonological awareness, and in the region of 0.3 for the CoPS measure of auditory discrimination as well as most of the other memory measures. Stepwise linear regression analyses showed that the CoPS tests of auditory‐verbal memory and phonological awareness administered at age 5 together accounted for 50% of the variance in reading ability at age 8, compared with only 29% of the variance being attributable to intelligence. It was concluded that short‐term memory is an important predictor variable for reading, in addition to the more generally acknowledged variable of phonological processing. Discriminant function analysis showed that CoPS tests provide a highly satisfactory prediction of poor reading skills, with very low or zero rates for false positives and false negatives. By contrast, a word recognition test given at age 6 was not found to predict reading at age 8 to the same degree of accuracy, resulting in an unsatisfactory false positive rate of 21%. Measures of verbal and nonverbal ability at age 6 produced unacceptably high false positive rates between 50% and 70%. These findings are discussed in relation to the prediction of children at risk of reading failure. The potential of computer‐based cognitive profiling for facilitating differentiated teaching in early reading is also considered.  相似文献

The current study investigated the development of children's performance on tasks that have been suggested to underlie early mathematics skills, including measures of cardinality, ordinality, and intelligence. Eighty‐seven children were tested in their first (T1) and second (T2) school year (at ages 5 and 6). Children's performance on all tasks demonstrated good reliability and significantly improved with age. Correlational analyses revealed that performance on some mathematics‐related tasks were nonsignificantly correlated between T1 and T2 (number line and number comparison), showing that these skills are relatively unstable. Detailed analyses also indicated that the way children solve these tasks show qualitative changes over time. By contrast, children's performance on measures of intelligence and nonnumerical ordering abilities were strongly correlated between T1 and T2. Additionally, ordering skills also showed moderate to strong correlations with counting procedures both cross‐sectionally and longitudinally. These results suggest that, initially, mathematics skills strongly rely on nonmathematical abilities.  相似文献

A paradigm of specialized brain hemisphere processing abilities was used to test cognitive skills and cognitive style in "learning-disabled" (LD) and "normal" children. Results indicate that (1) verbal ability is not a unitary factor, and LD children are deficient in only some aspects of verbal ability; (2) the LD group perform as well as the control group on right-hemisphere tests; (3) LD boys are more field sensitive (field dependent) than the control boys; (4) LD children may be attempting to use a nonverbal information processing mode to deal with academic tasks. The need for information on nonverbal processing skills in order to aid verbal processing is discussed.  相似文献
