Childbirth educators are responsible for providing expectant parents with evidence-based information. In this column, the author suggests resources where educators can find evidence-based research for best practices. Additionally, the author describes techniques for childbirth educators to use in presenting research-based information in their classes. A sample of Web sites and books that offer evidence-based resources for expectant parents is provided. 相似文献

An exploratory study which focused on teachers responses to the demand for role change brought about by the implementation of a new course is reported. Two procedures used to gather data were participant observation and open-ended interviews. Role theory, symbolic interaction, and schools as organizations were used as the frameworks for data analysis in this discursive qualitative study. The data reported describe the teachers' perceptions of factors influencing their willingness to change behaviors in order to comply with the role demands of the innovation. Hypotheses grounded in the data were generated and tied together into a theory which is illustrated by a structural model. The model shows interrelationships of factors influencing the teachers to change roles at the time of initiation of the new course through the ultimate incorporation of the innovation. 相似文献

An experimental interdisciplinary freshman course called The Systems Approach to the Universe was taught at North Carolina State University in the Spring of 1986. The goals of the course were to introduce principles of general systems theory; to provide examples through lectures and readings of applications of these principles in a wide variety of fields and disciplines; and to introduce and provide practice in critical questioning and evaluation. This paper outlines what was done, how it worked, and how the instructors and the students assessed the experience afterwards.He received his B.Ch.E. from the City College of New York, and his Ph.D. in chemical engineering from Princeton University.

A post hoc matching design was used to compare children who participated in the Home Instructional Program for Preschool Youngsters (HIPPY) throughout Arkansas to children from the same classrooms who had no preschool experience and children who had other preschool experiences in the third and sixth grades. The program showed modest positive impact on school suspensions, grades, classroom behavior, and achievement test scores at both grade levels. 相似文献

Conclusion As you can see, this is a rather holistic view. These categories may have to be expanded depending on the particular needs
of your task. However, it seemed to be efficient. This process may also be applicable to other situations such as student
papers. This was my attempt to compare texts with a minimal amount of bias. I welcome input of others in an effort to expand
and refine this rubric. 相似文献

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined. 相似文献
