The clinical use of ultrasound has dramatically increased, necessitating early ultrasound education and the development of new tools in ultrasound training and assessment. The goal of this study was to devise a novel low-resource examination that tested the anatomical knowledge and technical skill of early undergraduate medical students in a gross anatomy course. The team-based ultrasound objective structured practice examination (OSPE) was created as a method for assessing practical ultrasound competencies, anatomical knowledge, and non-technical skills such as teamwork and professionalism. The examination utilized a rotation of students through four team roles as they scanned different areas of the body. This station-based examination required four models and four instructors, and tested ultrasound skills in the heart, abdominal vessels, abdominal organs, and neck regions. A Likert scale survey assessed student attitudes toward the examination. Survey data from participants (n = 46) were examined along with OSPE examination grades (n = 52). Mean and standard deviations were calculated for examination items and survey responses. Student grades were high in both technical (96.5%). and professional (96.5%) competencies with structure identification scoring the lowest (93.8%). There were no statistical differences between performances in each of the body regions being scanned. The survey showed that students deemed the examination to be fair and effective. In addition, students agreed that the examination motivated them to practice ultrasound. The team-based OSPE was found to be an efficient and student-favored method for evaluating integrated ultrasound competencies, anatomical knowledge, team-work, and professional attributes.  相似文献

As an essential department at a higher education institution and an informal learning space, little is known about how academic libraries contribute to student learning on campus. The Olin Library sought to learn the role of library space in our users' learning. We surveyed users about their learning behaviors in a specific space prior to a scheduled renovation and then in the same space after. We wanted to determine how the renovation changed users' perceptions of their learning behaviors in that space.  相似文献

Abstract

This paper considers the emergence of amateur women’s rowing between the late nineteenth and early twentieth centuries, in light of contemporaneous social norms relating to gender and sport. It does not seek to identify a foundational point for women’s rowing, nor does it offer a comprehensive survey of the development of the sport over this period. Instead, it considers women’s rowing in three key contexts: women’s university colleges, at the end of the nineteenth century; the first women-only rowing club on the Thames, established in 1896 by Dr Frederick Furnivall; and the formation of a governing body for the women’s sport in 1923. Analysis of the conditions within the sport in these environments, and their implications, leads to more nuanced consideration of the women’s sport, and of gender as a normative social construct more widely. Discussion focuses on gendered influences on sporting behaviour, manifested in institutional regulation and hegemonic authority, and the intersection of class and gender.  相似文献

Research Findings: Using a qualitative research approach, this article explores teachers’ roles as scaffolders of infants’ play and the changing nature of their individualized support for infants’ learning and development through play in an infant group care setting. Three infant teachers in a child care center were followed over 3 months. Observations, interviews, ongoing conversations, e-mails, and reflective notes were used as data sources. Findings revealed that the teachers thought deeply about their roles as supporters of infants’ play, and they made intentional choices in scaffolding infants’ play. Each teacher's ways of empowering infants in play were grounded in her views of infants as learners and were individualized to accommodate children's unique learning styles and personalities. Practice or Policy: This study provides a window into the ways in which teachers working with the youngest children can set the stage for later learning.  相似文献

As elite youth sport becomes more organized and professionalized, the role of the family is increasingly acknowledged as being significant in the development of young talent. High-profile examples across a range of professional sports, both positive and negative, have drawn attention toward this important stakeholder. Accordingly, this review first examines the key issues in relation to family involvement in talent development in relation to what is perceived as good and bad practice on behalf of the family. Next the key theoretical underpinning is considered, Family Systems Theory, and how it may be integrated within elite youth sport. Finally, the article concludes with a summary of where the current literature leaves us and where we can progress from here. Two possible inputs are suggested that could benefit the effectiveness of family involvement: a focus on the family holistically and a second on the role different family members can play.  相似文献

While the number of Aboriginal and Torres Strait Islander students in higher education in Australia has doubled in recent years, the gap between their attainment and the attainment of other Australians has remained consistent. It is essential to elucidate the factors that promote Aboriginal and Torres Strait Islander students' academic success, not in order to justify the exclusion of these students from tertiary education, but to refine and develop curriculum and management strategies which promote their academic success. This study focuses on Aboriginal and Torres Straight Islander students' experiences in a diploma program offered in block mode, in order to better understand the ‘on-’ and ‘off-’ campus experiences which are related to academic success and the factors which challenge or enhance students' study. The research yields important findings related to students' motivations to enrol and their definitions of academic success; the challenges they experience in making the transition to tertiary study; the vulnerability of our students' determination to succeed; the effects of being in a program for Aboriginal and Torres Strait Islander students; and the ways in which minor challenges, if unresolved, can accumulate to interfere with students' study.  相似文献
