Evidence was collected regarding changes over 3 years in the quality of a preprimary program in rural Bangladesh and differences in school achievement of children who did and did not attend. The quality of 30 preprimary schools was evaluated using the ECERS-R (Early Childhood Environment Rating Scale - Revised) and ECERS-E (- Extension). Results indicated that the quality improved overall from 3.50 in 2006 to 5.24 in 2008. Samples of 180 graduates of these schools were annually followed into first and second grades and tested for five competencies: speaking, writing, reading, oral mathematics and written mathematics. Their achievement scores were compared with students in their classrooms and students in neighboring schools who did not have the opportunity to attend preprimary schools. First graders in 2008 performed significantly better than comparisons in all competencies, and better than earlier graduates. Second graders performed significantly better than comparisons on all but Reading. Qualities of the math preprimary program correlated with math achievement in Grade 1 only. Consequently the quality of the preprimary program improved over time along with higher achievement for its graduates. The findings support efforts to expand high-quality programs in developing countries to help children succeed in the early primary grades. 相似文献

The article reports on a study investigating influences on Australian politicians’ decision making for early childhood education and care (ECEC) policy. The astronomical concept of dark matter is utilised as a metaphor for considering normalising, and therefore frequently difficult to detect and disrupt, influences implicated in politicians’ decision making for ECEC policy. The concept of dark matter connects with and extends Foucauldian conceptualisations of knowledge, power and discourse. The paper argues that maternalist discourses continue to shape the policy landscape for ECEC, though these are largely unacknowledged. 相似文献

Developmental Relations Between Vocabulary Knowledge and Reading Comprehension: A Latent Change Score Modeling Study 下载免费PDF全文
Jamie M. Quinn Richard K. Wagner Yaacov Petscher Danielle Lopez 《Child development》2015,86(1):159-175
The present study followed a sample of first‐grade (N = 316, Mage = 7.05 at first test) through fourth‐grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and reading comprehension to test for the presence of leading and lagging influences. Univariate models indicated growth in vocabulary knowledge, and reading comprehension was determined by two parts: constant yearly change and change proportional to the previous level of the variable. Bivariate models indicated previous levels of vocabulary knowledge acted as leading indicators of reading comprehension growth, but the reverse relation was not found. Implications for theories of developmental relations between vocabulary and reading comprehension are discussed. 相似文献

The current study examined factors related to older adults’ perceptions of Internet use. Three hundred ninety five older adults participated in the study. The factor analysis revealed four factors perceived by older adults as critical to their Internet use: social connection, self-efficacy, the need to seek financial information, and the need to seek health information. Key differences were found between previous research and the factors extracted in this study. The regression analysis demonstrated that variables like health condition, financial status, computer experience, and life satisfaction significantly predict, at various levels, factors perceived by the older adults to affect Internet use. The significance of the study as well as its implications for research and practice are discussed. Suggestions are made for future research and practice. 相似文献
