In response to the scientific evidence documenting both profound developmental changes in sleep and circadian biology during adolescence and the myriad of negative health, performance, and safety outcomes risks associated with chronic sleep loss, at least 70 public school districts in the United States, representing approximately 1,000 schools, have successfully implemented a delay in high school start times. However, despite the compelling evidence supporting school start time change as a key strategy in addressing the epidemic of adolescent sleep loss, many school districts across the country with early high school start times have not considered the option to implement later bell schedules for adolescents. Moreover, while the current scientific literature has clearly documented the positive outcomes associated with delayed high school start times, these studies contain limited information regarding the process by which school districts consider, approve and implement bell schedule changes. Thus, this in‐depth examination of those school districts that have been successful in changing their bell schedules is intended to support the efforts of other districts in various stages of contemplating this measure. We utilized a multi‐pronged approach (literature review, case studies, telephone interviews, online survey) to summarize the experiences of school districts across the United States in regard to challenges faced, strategies employed, and lessons learned in the hope that this information will be a useful tool for other school districts looking to chart a course forward to promote the health, safety, and academic opportunities of their students. 相似文献

There are limited empirical data on curriculum in two‐year colleges; this study is designed to address that lack. A literature review is used to identify the functions served by credit courses: transfer, general education, preparation for work, and remediation. Secondary analysis is made of data gathered on a 1977 survey of science, social science, and science‐related technical courses. Instructor perceptions of course purpose(s) are used to determine if the identified functions are served. The findings indicate these functions are served, but predominately as combined functions rather than the discrete functions identified in the literature. Patterns of multiple course functions are identified by academic area and by course. Further, the methodology used is presented as a useful tool in developing empirical data about college curricula. 相似文献

Research in the United States suggests that teachers view Black students' misbehavior as more likely to reoccur, but such research has not disentangled the effect of race from related factors. We used conjoint analysis to experimentally test the effect of multiple student characteristics on the chances of being referred for a behavior intervention program. Although preservice teacher participants were not more likely to refer Black students, they were more likely to refer students who had lower grades, lived in poverty, lived with a single mother, and had been retained. We interpret these results and highlight directions for future research and practice. 相似文献

Ultrasonography is increasingly used in medical education, but its impact on learning outcomes is unclear. Adding ultrasound may facilitate learning, but may also potentially overwhelm novice learners. Based upon the framework of cognitive load theory, this study seeks to evaluate the relationship between cognitive load associated with using ultrasound and learning outcomes. The use of ultrasound was hypothesized to facilitate learning in anatomy for 161 novice first‐year medical students. Using linear regression analyses, the relationship between reported cognitive load on using ultrasound and learning outcomes as measured by anatomy laboratory examination scores four weeks after ultrasound‐guided anatomy training was evaluated in consenting students. Second anatomy examination scores of students who were taught anatomy with ultrasound were compared with historical controls (those not taught with ultrasound). Ultrasound's perceived utility for learning was measured on a five‐point scale. Cognitive load on using ultrasound was measured on a nine‐point scale. Primary outcome was the laboratory examination score (60 questions). Learners found ultrasound useful for learning. Weighted factor score on “image interpretation” was negatively, but insignificantly, associated with examination scores [F (1,135) = 0.28, beta = ?0.22; P = 0.61]. Weighted factor score on “basic knobology” was positively and insignificantly associated with scores; [F (1,138) = 0.27, beta = 0.42; P = 0.60]. Cohorts exposed to ultrasound had significantly higher scores than historical controls (82.4% ± SD 8.6% vs. 78.8% ± 8.5%, Cohen's d = 0.41, P < 0.001). Using ultrasound to teach anatomy does not negatively impact learning and may improve learning outcomes. Anat Sci Educ 10: 144–151. © 2016 American Association of Anatomists. 相似文献

This paper looks at an aspect of the two‐year college: that it is the logical system for achieving educational equality in higher education. The authors find that low aptitude blacks are overrepresented at four‐year colleges, that blacks are less likely than whites to meet aspirations of attending four‐year colleges, and that attending a two‐year college is related to reduced probability that four‐year education will be realized. 相似文献

A comparative study of conservation development in partially sighted, sighted, and sighted blindfolded children at four age levels (6–7, 8–9, 10–11, and 12–15 yrs.) was assessed. Conservation on tasks of mass, weight, and volume were evaluated using Piaget and Inhelder's (1941) prediction, judgment, and explanation questions. The significant differences were found between groups, task, and age level. Visually impaired children's performance was inferior to sighted children at all age levels, while little difference was found between partially sighted and blindfolded children's performance. For all three groups, conservation of mass was easiest, followed by conservation of weight, then volume. The findings support the notion of a developmental lag in cognitive skills for partially sighted children. 相似文献
