Many states require children to reach age 5 by a specified date in the calendar year in order to begin kindergarten. We use birth certificate records from 1999 to 2004 to assess whether parents systematically time childbirth before these eligibility cutoff dates to capture the option value of sending their child to school at a relatively young age, thereby avoiding a year of child care costs. Testing for discontinuities in the distribution of births around cutoff dates, we find no evidence that the option value influences the timing of birth. Similarly, we find no systematic discontinuities in average mothers’ characteristics or babies’ health outcomes around cutoff dates. Timing in the neighborhood of eligibility cutoffs occurs only when the cutoffs coincide with weekends or holidays, which may have implications for recent research that assumes birth dates in the neighborhood of cutoffs are essentially randomly assigned.  相似文献

This study is based on an intervention designed to enhance early childhood teacher candidates' critical thinking abilities. The concept, elements, standards, and traits of critical thinking were integrated into the main course contents, and the effects of the intervention were examined. The results indicated that early childhood teacher candidates' dispositions toward critical thinking significantly increased after the intervention. In addition, their knowledge about critical thinking and ability to apply critical thinking in their own learning showed growth as well. Curricula implications for early childhood teacher preparation programs and instructional practices for teacher educators are discussed.  相似文献

This article provides a model for sustaining employee engagement through the application of the four functions of management. Training managers in using the four functions, with an emphasis on control, improves the sustainability of engagement efforts. Following is a brief primer of the four functions of management. The article provides practical steps to apply the functions to sustain employee engagement.  相似文献

The purpose of the study is to investigate the popular assumption that the “digital natives” generation surpasses the previous “digital immigrants” generation in terms of their technology experiences, because they grow up with information and communication technology. The assumption presumes that teachers, the digital immigrants, are less technology savvy than the digital natives, resulting in a disconnect between students’ technology experiences inside and outside of the formal school setting. To examine the intersection of these generations and their technology experiences, this study used a mixed-methods approach to survey and compare middle school science teachers’ (n = 24) and their students’ (n = 1,060) inside–outside school technology experiences, and conducted focus group interviews to investigate any barriers that prevented them from using technology in school. The findings imply that the concept of digital natives may be misleading and that the disconnect between students’ inside–outside school technology experiences may be the result of the lack of sufficient teacher training concerning technology integration strategies.  相似文献

The Adolescent Sexual Health Work Group commissioned the development of core competencies that define the knowledge, skills, and attitudes necessary for all providers of adolescent sexual and reproductive health. This article describes the background and rationale for this set of competencies, the history and use of competencies, and the process involved in creating the core competencies. It explores the ways that educators can use them to strengthen classroom instruction and improve outcomes for adolescents in the area of reproductive health. Several additional tools that guide the application of the competencies to human resources, self-assessment, performance assessment, professional development, and program evaluation are described.  相似文献

Through an extensive content analysis of 14 years of television nightly news stories, evidence is presented showing coverage of homelessness corresponded more to seasonal variations than actual changes in the plight of the homeless. In addition, news coverage appeared to reify boundaries between the acceptable and the unacceptable while masking socioeconomic factors central to homelessness during the 1980s and early 1990s. Finally, implications are drawn concerning the likely effects of news portrayal of homelessness as an individual problem requiring individual acts of kindness rather than a systemic problem demanding institutional and societal change.  相似文献
