Substantial evidence documents the superiority of breastfeeding for mothers and breastmilk for babies. Although the American Academy of Pediatrics and the U.S. Healthy People 2010 initiative promote breastfeeding, current breastfeeding rates often fall short of recommendations. This study determined factors associated with exclusive breastfeeding 2 to 4 weeks following discharge from a large, urban, academic medical center striving for Baby-Friendly designation. Results indicated that mothers who breastfed within the first hour of birth (61%) were significantly more likely to be exclusively breastfeeding 2 to 4 weeks after discharge. Incorporating care practices that include a number of the "Ten Steps to Successful Breastfeeding," as recommended by the Baby-Friendly Hospital Initiative, may increase the duration of exclusive breastfeeding after discharge. 相似文献

Radford University was recently configured with a campus-wide wireless local area network. Using these new capabilities, a
classroom-based Honors section of Concepts of Biology was conducted solely using electronic technologies (paper was never
transferred from professor to student). To accomplish this, students used common software and freeware. Commercial versions
of similar software are designed solely for academic use, however, here the students were trained to use software and technologies
that will be available to them once leaving the institution. Overall, students in this course responded favorably to the use
of technology and reported that it aided in their learning process. 相似文献

In order to evaluate the effectiveness of an experimental elementary mathematics field experience course, we have designed
a new assessment instrument. These video-based prediction assessments engage prospective teachers in a video analysis of a
child solving mathematical tasks. The prospective teachers build a model of that child’s mathematics and then use that model
to predict how the child will respond to a subsequent task. In this paper, we share data concerning the evolution and effectiveness
of the instrument. Results from implementation indicate moderate to high degrees of inter-rater reliability in using the rubric
to assess prospective teachers’ models and predictions. They also indicate strong correlation between participation in the
experimental course and prospective teachers’ performances on the video-based prediction assessments. Such findings suggest
that prediction assessments effectively evaluate the pedagogical content knowledge that we are seeking to foster among the
prospective teachers. 相似文献

Predoctoral interns' responses to an internship supervision training questionnaire indicated that counseling center interns supervised more trainees, received more supervision in their supervisory roles, reported more supervision training activities, and yielded higher supervisor development scores than did non‐counseling‐center interns. A qualitative analysis of participants' responses showed that non‐counseling‐center interns desired more supervision training and opportunities to provide supervision during their internship year than did counseling center interns. 相似文献

Students who engage in challenging behaviour compromise the fundamental ability of schools to educate children. Consequently, teachers face the daunting task of designing effective strategies to promote positive educational outcomes for their students. Since the 1997 Individuals with Disabilities Education Act amendments, the use of positive behaviour supports (PBS) to address the behavioural needs of children challenged by disabilities has expanded. There is evidence to support the utility of PBS in reducing challenging behaviour among students. However, successful schools are also gauged by the academic achievement of their students. Hence, it is important to examine the extent to which behavioural outcomes are related to academic outcomes. The purpose of this paper is to examine the extent to which PBS interventions aimed at reducing challenging behaviour result in corresponding improvement in academic achievement. A meta‐analysis of extant research indicated a positive correlation of 0.40 between improvement in problem behaviour and academic achievement.

We revisit the relationship between attendance and performance in the undergraduate university setting and apply agency theory in the instructor–student context. Building on agency theory propositions in the educational setting advanced by Smith, Zsidisin, and Adams (2005) , we propose that the student and instructor must align goals to promote the student's achievement of performance learning outcomes, and attendance functions as a behavior‐based alignment mechanism to encourage the convergence of faculty and student interests. Further, we propose that attendance does not equally affect lower‐ and higher‐performing students and that absences are also negatively related to students' cumulative grade point average. We test these hypotheses with data from undergraduates enrolled in management courses at a state university in the southeast. Our results show that attendance is positively related to exam performance, there are more pronounced negative effects of an absence for lower‐performing students than for higher performers, and absences are negatively related to a student's cumulative grade point average. We discuss the implications of our findings for students, instructors, and universities as well as practice in teaching and learning. 相似文献

OBJECTIVE: This study examined specific aspects of child sexual abuse in relation to symptom severity among hospitalized patients diagnosed with bulimia nervosa. METHOD: Participants were 45 hospitalized bulimic women who reported a history of child sexual abuse. Structured interviews were conducted in order to obtain detailed information regarding specific features of the abusive event(s). Participants also completed instruments that measured depression and eating pathology. RESULTS: There were no significant differences in severity of depression or eating disturbance among women reporting differing abusive experiences including intrafamilial versus extrafamilial abuse, abuse with or without the use of physical force, one versus multiple incidents, early abuse versus abuse occurring after age 14, contact versus noncontact abuse, disclosed versus undisclosed, and combined physical/sexual abuse versus sexual abuse alone. CONCLUSION: The specific characteristics of child sexual abuse are not related to the level of symptomatology for hospitalized bulimic patients. This study suggests that differences in the nature of the abuse may not be as important as the fact that the abuse occurred in the first place. 相似文献

Meta-analysis was used to review the results of 25 studies that compared the classroom behavior of children and adolescents with learning disabilities (LD) to children without learning disabilities. The data were analyzed from several different methodological perspectives. Results showed that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities compared to their nondisabled peers in each of five overall areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Both observational and teacher rating data demonstrated these differences. Effect sizes for both groups of studies seemed to cluster around 1 standard deviation, suggesting noticeable and educationally significant impairment in the behavior of children with disabilities. Analysis of grade-level effect sizes suggests some explanation for the large number of referrals often witnessed during the elementary school years. Educational implications of these behavioral differences in terms of implications for mainstreaming are discussed. 相似文献

This study investigates the dialogic processes involved in how teachers talk about their students and what consequences their ways of talking (i.e., “narratives”) may have for their guidance. We take a sociocultural perspective on learning as transformation of students’ subjectivity. Teaching, as a process of guiding and facilitating learning, cannot be effective if the teacher does not actively seek how the student perceives and understands reality. We borrow and adapt from Bakhtin (1999) four narrative ways of talking about others: objectivizing, subjectivizing, problematizing and finalizing. The presence of these narratives in web discussion postings of our pre-service teachers about the Latino children they worked with in a community center are analyzed. We then compare their ways of talking about children with print- and web-based discussions about children made by in-service teachers, model teachers and our pre-service teachers in a school-based practicum. Using mixed quantitative and qualitative methodologies, we found an overwhelming predominance of objectivizing and finalizing in our pre-service teachers’ narratives about the children with whom they work that seems to define a certain pedagogical regime that we call here “teaching imaginary children/students.” This “way of talking” about children seems to be characterized by unchecked speculations guiding instruction that are not tested by finding out from the children themselves how they understand the instruction and the world. These speculations, in turn, can lead to a dogmatic approach towards children. 相似文献
