This meta-analysis examined associations between the quantity and quality of parental linguistic input and children’s language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of linguistic input. For quality and quantity of parental linguistic input, effect sizes were stronger when input was observed in naturalistic contexts compared to free play tasks. For quality of parental linguistic input, effect sizes also increased as child age and observation length increased. Effect sizes were not moderated by socioeconomic status or child gender. Findings highlight parental linguistic input as a key environmental factor in children’s language skills.  相似文献

Four meta-analyses examined relationships between morningness and cognitive ability (total N = 2177), eveningness and cognitive ability (total N = 1519), morningness and academic achievement (total N = 3220), and eveningness and academic achievement (total N = 700). The analyses focused on the population effect size (to reveal the effect across studies) and the homogeneity (to determine if the results of the several experiments are sufficiently similar to warrant their combination into an overall result). In all four cases, the aggregated correlations between chronotype and cognitive ability, as well as chronotype and academic achievement were found to be significant. Eveningness was found to be positively related to individuals' cognitive ability (r = .08), yet negatively related to indicators of academic achievement (r = −.14). Conversely, morningness had a negative relationship with cognitive ability (r = −.04) and a positive correlation with academic indicators (r = .16). Practical implications, including those pertaining to educational policy, are discussed.  相似文献

Abstract

A meta-analysis of vocabulary interventions in grades pre-K to 12 was conducted with 37 studies to better understand the impact of vocabulary on comprehension. Vocabulary instruction was found to be effective at increasing students' ability to comprehend text with custom measures (d = 0.50), but was less effective for standardized measures (d = 0.10). When considering only custom measures, and controlling for method variables, students with reading difficulties (d = 1.23) benefited more than three times as much as students without reading problems (d = 0.39) on comprehension measures. Gains on vocabulary measures, however, were comparable across reading ability. In addition, the correlation of vocabulary and comprehension effects from studies reporting both outcomes was modest (r = .43).  相似文献

Developmental science has increasingly scrutinized how environmental hazards influence child outcomes, but few studies examine how contaminants affect disparities in early skill formation. Linking research on environmental inequality and early childhood development, this study assessed whether differences in exposure to neurotoxic lead explain sociodemographic gaps in school readiness. Using panel data tracking a representative sample of 1266 Chicago children (50% female, 16% White, 30% Black, 49% Hispanic, μage = 5.2 months at baseline, collected 1994–2002), analyses quantified the contribution of lead contamination to class and racial disparities in vocabulary skills and attention problems at ages 4 and 5. Results suggested that lead contamination explains 15%–25% and 33%–66% of the disparities in each outcome, respectively, although imprecise estimates preclude drawing firm inferences about attention problems.  相似文献

Most U.S. preschoolers have consumed media created with funding from the U.S. Department of Education's Ready To Learn (RTL) initiative, which was established to promote school readiness among children ages 2–8. Synthesizing data from 45 evaluations (N = 24,624 unique child participants), this meta-analysis examined the effects of RTL media exposure on young children's literacy skills. Results indicate positive effects of RTL media exposure on children's literacy outcomes, especially vocabulary and phonological concepts. These effects are equivalent to about one-and-a-half months of literacy learning above and beyond typical growth. Findings are robust across a variety of research designs and for exposure to both television and new media. These results are discussed in terms of accountability evidence for RTL and larger debates in scholarly understanding of educational media effects.  相似文献

Abstract

This study evaluated the effects of integrating science and social studies vocabulary instruction into shared book reading with low-income preschool children. Twenty-one preschool teachers and 148 children from their classrooms were randomly assigned at the class level to either the Words of Oral Reading and Language Development (WORLD) intervention or a practice-as-usual condition. Children were screened and selected to approximate three vocabulary levels (15th, 30th, and 50th). WORLD teachers implemented the intervention in small groups of 5 to 6 students, 5 days per week, 20 minutes per session, for 18 weeks. Findings from multilevel models indicated statistically and practically significant effects of the WORLD intervention on standardized measures of receptive vocabulary (δT = 0.93) and on researcher-developed measures of expressive (δT = 1.01) and receptive vocabulary (δT = 1.41). The WORLD intervention had an overall main effect, regardless of entry-level vocabulary, a finding that speaks to its potential applicability in preschool classrooms.  相似文献

Two studies on the role of video on vocabulary learning were conducted in kindergarten classrooms with substantial numbers of children from low-income and Dual Language Learning (DLL) backgrounds. In the first study (n = 78), the effect of video viewing was compared with the effect of book reading on vocabulary learning. In the second study (n = 89), the effect of repeated viewing of video was compared with the effect of single viewing of video on vocabulary learning. Pre-test and post-test receptive and expressive vocabulary measures, which were aligned with the content in the studies, were administered. Analysis of Variance was used to test the effect of condition (i.e., video viewing versus book reading and single versus repeated reading) on children’s word knowledge. Results showed no difference in vocabulary learning between the video viewing and book reading conditions. Findings showed that there was no difference in vocabulary learning between children in the single and repeated viewing condition on the receptive measure, but children in the repeated viewing condition showed higher gains in vocabulary on the expressive measure. No differences were found in either study between children with higher and lower vocabulary knowledge.  相似文献

A meta‐analysis of the relationship between attitudes in reading and achievement in reading was conducted to provide a statistical summary to the observed variability in the magnitude of previously reported effect sizes. A total of 32 studies, with a total sample size of 224,615 were used, and included a total of 118 effect sizes. A multi‐level approach was used in meta‐analysis to determine if variance in the magnitude of effect sizes could be partitioned to study (level 1) and moderator (level 2) levels by using a mixed model approach. Results from the meta‐analysis indicated that the mean strength of the relationship between reading attitudes and achievement is moderate (Zr=.32), while stronger for students in elementary school (Zr=.44) when compared with middle school students (Zr=.24). Findings related to selected moderator variables are discussed, with suggestions for future research.  相似文献

This systematic review and meta-analysis considered evidence of guided play compared to direct instruction or free play to support children's learning and development. Interventions from 39 studies were reviewed (published 1977–2020); 17 were included in meta-analysis (Ntotal = 3893; Mchildage = 1–8 years; Mgirls 49.8%; Methnicity White 41%, African American/Black 28%, Hispanic 19%). Guided play had a greater positive effect than direct instruction on early maths skills (g = 0.24), shape knowledge (g = 0.63), and task switching (g = 0.40); and than free play on spatial vocabulary (g = 0.93). Differences were not identified for other key outcomes. Narrative synthesis highlighted heterogeneity in the conceptualization and implementation of guided play across studies.  相似文献

This study examined the effects of reading interventions from single‐case design studies for students with and at‐risk of emotional and behavioral disorders in grades K–12 using a quantitative synthesis. Seventeen studies met the selection criteria of having one more dependent variables meeting what works clearinghouse (WWC) design standards with or without reservations. Although students’ reading performance significantly improved from baseline to intervention phases (p < 0.001), the overall weighted average effect size was weak (Tau‐U = 0.58, 95% confidence interval = [0.54, 0.63]; d = 0.29); smaller effects were found on reading comprehension. Interventions were less effective for students in secondary grades, students with a comorbid disability, and students in substantially separate settings. While no studies meeting the selection criteria were conducted in inclusive settings, the teacher provided interventions were more effective than those provided by researchers suggesting the importance of the student–teacher relationship for reading instruction. Study limitations, areas for future research, and implications for school practices are discussed.  相似文献

The goal of this study was to explore links among shyness, receptive vocabulary, and indices of socioemotional functioning in a sample of young children in mainland urban China. In particular, we sought to examine the potential moderating role of receptive language in these relations. Participants were N = 360 young children (200 boys, 160 girls, Mage = 4.72 years, SD = 0.63) attending preschool/kindergartens in Shanghai, People’s Republic of China. Multisource assessments were employed, including maternal ratings (child shyness), standardized tests (receptive vocabulary), child self-reports collected during individual interviews (loneliness), teacher ratings (child internalizing problems), and peer nominations (peer liking). Results indicated that receptive vocabulary moderated (buffering effect) the relations between shyness and several indices of socioemotional functioning. Results are discussed in terms of the implications of language skills for early school adjustment of young shy Chinese children.  相似文献

Political violence affects more than 25% of children globally, yet little is known about how to support positive adaptation among conflict-affected children. Using a sample of 3797 Nicaraguan child-caregiver dyads (MAgeTime1 = 1.5 years, MAgeTime2 = 5.9 years; 51% male), this registered report used a novel quasi-experimental approach to examine how exposure to political violence relates to child and caregiver outcomes, and to test three policy-relevant moderators: participation in a large-scale home visit parenting program, household economic disruption, and media exposure. Results revealed positive associations between political violence and harsh discipline practices (0.33 SD), but there was no evidence that political violence affected children's behavior, caregiver depressive symptoms, or responsive parenting practices, and there was no evidence of moderation.  相似文献

Abstract

This meta-analytic review examines how word-learning interventions affect young children, at risk for reading difficulties, on vocabulary outcomes. We quantitatively reviewed 51 studies with 138 effect sizes (N = 7,403) to assess the association between vocabulary training and word learning. Using a random-effects model, we found a mean effect size of nearly 1 standard deviation indicating a strong training effect overall. Moderator analyses indicated that children from low-socioeconomic-status (SES) families experienced significantly lower word-learning gains than those from middle- and upper-SES families who had one or more risk factor (e.g., English Language Learner, language delays). This was true regardless of the total number of risk factors present. However, risk factors in addition to poverty did compound this SES disadvantage. Further, multivariate meta-regression analyses indicated that the sole risk factor associated with lower effect sizes was poverty controlling for all other risk factors. Subgroup moderator analyses indicated a number of instructional and pedagogical factors associated with greater effect sizes. Taken together, these results highlight the importance of creating interventions powerful enough to accelerate children's vocabulary development if we are to narrow the reading achievement gap.  相似文献

We investigated whether and how standardized behavioral measures of reading and electrophysiological measures of reading were related in 72 typically developing, late elementary school children. Behavioral measures included standardized tests of spelling, phonological processing, vocabulary, comprehension, naming speed, and memory. Electrophysiological measures were composed of the amplitude of the N400 component of the event‐related potential waveform elicited by real words, pseudowords, nonpronounceable letter strings, and strings of letter‐like symbols (false fonts). The only significant brain–behavior correlations were between standard scores on the vocabulary test and N400 mean amplitude to real words (r = ?.272) and pseudowords (r = ?.235). We conclude that, while these specific sets of standardized behavioral and electrophysiological measures both provide an index of reading, for the most part they are independent and draw upon different underlying processing resources.  相似文献

This meta-analysis (k = 35, N = 11,629) examines the effect that listening to music, particularly popular music, has on consumers. Results demonstrate that listening to music generates an effect on listeners consistent with the content of the music (average r = .210, k = 35, N = 11,629). This effect was similar when considering survey research (r = .227) or experimental research (r = .265). The tenets of excitation transfer theory received some support, particularly when considering the effects of music as a priming material (r = .399), demonstrating the impact of music as a means of establishing mood, and ultimately the subsequent reactions of individuals. One conclusion is that efforts toward media literacy or education may prove far more productive than media content restrictions when attempting to curb potential undesirable media effects. Additional implications for policy and theory are discussed.  相似文献

Forty anatomy articles were sampled from English Wikipedia and assessed quantitatively and qualitatively. Quantitatively, each article’s edit history was analyzed by Wikipedia X-tools, references and media were counted manually, and two readability indices were used to evaluate article readability. This analysis revealed that each article was updated 8.3 ± 6.8 times per month, and referenced with 33.5 ± 24.3 sources, such as journal articles and textbooks. Each article contained on average 14.0 ± 7.6 media items. The readability indices including: (1) Flesch–Kincaid Grade Level Readability Test and (2) Flesch Reading Ease Readability Formula demonstrated that the articles had low readability and were more appropriate for college students and above. Qualitatively, the sampled articles were evaluated by experts using a modified DISCERN survey. According to the modified DISCERN, 13 articles (32.5%), 24 articles (60%), 3 articles (7.5%), were rated as “good,” “moderate,” and “poor,” respectively. There were positive correlations between the DISCERN score and the number of edits (r = 0.537), number of editors (r = 0.560), and article length (r = 0.536). Strengths reported by the panel included completeness and coverage in 11 articles (27.5%), anatomical details in 10 articles (25%), and clinical details in 5 articles (12.5%). The panel also noted areas which could be improved, such as providing missing information in 28 articles (70%), inaccuracies in 10 articles (25%), and lack or poor use of images in 17 articles (42.5%). In conclusion, this study revealed that many Wikipedia anatomy articles were difficult to read. Each article’s quality was dependent on edit frequency and article length. Learners and students should be cautious when using Wikipedia articles for anatomy education due to these limitations.  相似文献

This study sought to compare how three different gloss types (text–picture, text–audio and text–picture–audio) affected English as a foreign language (EFL) learners' reading comprehension and vocabulary acquisition. The study also compared how results on comprehension and vocabulary acquisition differed across three learning conditions (i.e., incidental, intentional and explicit instruction). A between‐groups design was employed with four groups (N = 135) of Iranian university learners of L2 English. The participants (with upper‐intermediate proficiency level) read English texts. Written recall and multiple‐choice questions were used to measure reading comprehension; vocabulary knowledge scale (VKS) and contextualized vocabulary knowledge test (CVKT) were used to assess vocabulary acquisition. Results of statistical analyses revealed that while the text–picture–audio gloss type consistently resulted in better vocabulary learning and reading comprehension, the learning conditions varied in terms of their immediate and delayed effect on vocabulary and reading scores. This study suggests that learner performances across gloss types are condition specific and provides both pedagogical and theoretical implications. What is already known about this topic
  • Electronic glosses foster reading comprehension and vocabulary acquisition.
  • There are different positions about the effectiveness of form focused instruction in grammar, with the focus on forms approach having a higher acceptable rate in SLA. But, this issue has been rarely researched in vocabulary acquisition.
What this paper adds
  • This study supports the complementary nature of dual annotations in vocabulary learning and reading comprehension.
  • This study extends the issue of form focused instruction to vocabulary learning by comparing the incidental, intentional and incidental–intentional learning orientations.
  • This study evaluates the interaction between the multiple gloss types and the learning orientations.
Implications for theory, policy or practice
  • This study provides both pedagogical and theoretical implications.

Abstract

In this experimental study, we examined the effects of a technology-mediated intervention to improve students’ understanding of academic vocabulary and its impact on measures of vocabulary and comprehension. The Vocabulators program was implemented in two states involving 24 teachers and 200 third-grade students identified as in need of supplemental vocabulary instruction. Individual students within each classroom were randomly assigned to treatment (n?=?100) or typical instructional practices (n?=?100) conditions. In the treatment condition, students received, on average, 29 lessons on vocabulary and comprehension. Results of linear regression analyses showed statistically significant and practical effects on experimenter-developed proximal measures of decoding (ES = 0.52), expressive vocabulary (ES = 0.78), receptive vocabulary (ES = 0.51), and near transfer measures of understanding vocabulary in sentences (ES = 0.65), and informational text comprehension (ES = 0.28). Group performance did not differ statistically on near transfer measures of sentence verification with vocabulary and narrative text comprehension as well as distal standardized measures of general vocabulary or reading comprehension. Findings suggest the potential impact of technology-based vocabulary/comprehension lessons to supplement typical instruction.  相似文献

Abstract

Researchers have argued that media exposure involving criminal justice can influence perceptions of police, but empirical research is decidedly mixed. Additionally, some scholars argue that media effects depend on audience characteristics. However, the moderating role of academic major remains unexplored. Using a laboratory-style randomized experiment (N?=?270), the current study examines the impact of media exposure that contains conflicting images of the police on perceptions of police and if this effect varies depending on academic majors by performing a series of paired t-tests, independent-samples t-tests, and a mixed between-within subjects analysis of variance. Findings show that exposure to mixed images of the police dampens confidence in the police, but this effect is pronounced among non-CJ majors compared to CJ majors. Expanding our knowledge base in differential media effects between CJ majors and non-CJ majors can offer useful insights into future CJ curricula.  相似文献

This longitudinal study examined the reciprocal associations between paternal and maternal rejection and firstborn children's (Mage = 49.9 months; 55% boys) behavior problems across the transition to siblinghood in a sample of 120 families recruited from 2016 to 2018 from Shanghai, China. Parental rejection and behavior problems were assessed before (prenatal) and 1, 6, and 12 months after the birth of a baby sibling. Random intercept cross-lagged panel models revealed positive relations between internalizing problems and both maternal and paternal rejection, and between externalizing problems and paternal rejection at the between-person level (rs = .32–.37), but only cross-lagged effects from children's internalizing and externalizing problems to maternal rejection at the within-person level (βs = .30–.54).  相似文献
