Issues surrounding cesarean birth are of interest to researchers from varied disciplines and nations. In this column, three studies that examine aspects of cesarean birth are reviewed. One study presented a review of 11 studies and found differences in the perceptions of white and minority mothers toward labor, vaginal birth, and cesarean birth. In a second study on infant outcomes, Japanese researchers found differences in transient tachypnea in infants born in the first half of the 37th week gestation and those born in the second half of the 37th week and the 38th week of gestation. In a third study conducted in Norway, researchers found more complications when cesarean birth occurred at advanced dilation. The three studies' implications for childbirth educators are discussed. 相似文献

从教学的角度分析WebQuest的作用,认为WebQuest有利于激发学生的学习兴趣;培养学生的探索、研究精神;有利于培养学生的团队协作意识,形成协作学习方式;有利于提高学生的思维水平,培养学生的创新意识和能力;有利于学生的全面发展。同时WebQuest还存在不适合所有课程内容的教学和学习、一定程度上限制了老师的思维、学生很难一直都保持较高的积极性和投入高水平的思维等局限性。 相似文献

随着我国新一轮基础教育课程改革的深入,教师教育面临新的挑战,其功能需要进行新的角色认知。本文认为,现阶段我国教师教育应该重新审视其与基础教育改革的关系,确立其适应和引领基础教育课程改革的新功能。变被动适应为主动适应,并能够积极引领基础教育的课程改革。为此,教师教育应该通过新课程理念的更新、新课程知识的储备、新课程技能的训练、新课程研究能力的提升,为推动我国新课程改革的进一步深化培育"新师资"。 相似文献

This study investigated how an authentic assessment program was used to examine student learning outcomes within the context of a Christian university’s institutional mission, core values, and distinctive qualities. For the purposes of this study, an authentic assessment program is defined as assessing student-produced work within the context of the institutional mission. A sample of 1,814 undergraduate students taking one or more general education courses at the university during the 2007–2009 academic years was examined for any significant differences in student learning outcomes. A univariate analysis of covariance (ANCOVA) indicated the Student Assessment System (SAS) scores for the online students were not significantly different from the SAS scores for the face-to-face (F2F) students after controlling for course grade. These results suggest that online students achieved the same critical mission-related educational outcomes that the university required of its F2F students. An implication of this finding is that the university just as effectively articulated its faith-based mission and vision to the online students as it did to its students taking classes F2F. 相似文献

电大现行远程教学模式评析 总被引:1,自引:0,他引:1
现代远程教育是我国高等教育走向大众化的有效途径,是社会关注的热点,也是目前高校研究和探讨的重要课题。电视大学是中国远程教育的主力军,如何走出一条适合我国国情,适合电大发展的远程教育之路,是电大工作者的使命。本文是远程教育模式研究的一个子课题,重在反思电大现行教学模式存在的问题,并提出个人的见解,只有对现行模式的利弊做出正确的分析,才谈得上制定创建新模式的策略。 相似文献

When Parents Ask ... about Preterm Birth, Breastfeeding Success, Breast Cancer, or Waterbirth 下载免费PDF全文
Moore ML 《The Journal of perinatal education》2003,12(4):40-43
IN THIS COLUMN, THE AUTHOR REVIEWS RESEARCH ON FOUR SEPARATE TOPICS: the prevention of preterm birth, the effect of epidurals on breastfeeding success, the possible protective effect of lactation on breast cancer, and laboring in water. In two separate studies-a multisite study in the United States and a second study from Brazil-natural progesterone was shown to significantly reduce the incidence of preterm birth in women at high risk. A third study conducted in the United Kingdom examined the effect of clindamycin on preventing infection that can lead to preterm birth. A group of studies related to lactation found that early breastfeeding was more successful in women who did not have epidural anesthesia. In a Korean study, the lifetime duration of breastfeeding was associated with a significant reduction in breast cancer. Concerning waterbirth, Swiss researchers found that, when a woman labored in water, she regulated both water temperature and bathing duration to ensure that her body temperature and that of the fetus remained within a normal physiological range. 相似文献

Misoprostol (Cytotec) is a synthetic prostaglandin E1 analogue that was designed for the prevention and treatment of peptic ulcer associated with the use of nonsteroidal anti-inflammatory drugs. In obstetrics, misoprostol has been administered for induction of first and second trimester abortion, for induction of labor in the third trimester, and to control postpartum hemorrhage. None of these uses has been approved by the Food and Drug Administration. Nevertheless, misoprostol is widely used in the United States and throughout the world. Advantages are cited as reduced rate of cesareans, shorter time from induction to birth and, particularly in developing countries, lower cost, oral, vaginal or rectal administration, and stability without refrigeration. Disadvantages are uterine hyperstimulation and, in rare instances, uterine rupture and death. Mothers should be informed of both the risks and the possible benefits of misoprostol. Further research with large samples is necessary to determine whether the risks outweigh any possible benefits. 相似文献

Pigeons’ performance of a delayed conditional discrimination with presence versus absence of conditional (sample) stimuli was examined in two experiments. The pigeons showed steeper retention functions with feature (i.e., presence) samples (either food or yellow) than with no-feature (i.e., absence) samples (either no food or no yellow). These results suggest that pigeons code features and respond only by default to test stimuli (comparisons) associated with no features. In contrast, the overall superiority of performance on no-feature-sample trials compared with feature-sample trials in both the food/no-food- and yellow/no-yellow-sample tasks was reversed at a 0-sec delay in the food/no-food-sample group, but not in the yellow/non-yellow-sample group. This difference in results with hedonic versus nonhedonic samples suggests that the crossover in delay performance on food/no-food-sample trials is produced by the formation of backward associations between the food-associated comparison stimulus and the food sample. 相似文献
