Dissecting through Barriers: A Follow-up Study on the Long-Term Effects of Interprofessional Education in a Dissection Course with Healthcare Professional Students     

Yu Hang Zheng  Andrew Palombella  Jenn Salfi  Bruce Wainman 《Anatomical sciences education》2019,12(1):52-60

Several studies have shown significant improvements in the attitudes and perceptions of healthcare professional students toward interprofessional education (IPE) immediately following intervention with IPE courses. However, there remains little evidence on the lasting effects of IPE courses and the long-term influences of these IPE experiences are poorly documented. The purpose of this study is to assess the long-term effects of an intensive, ten-week interprofessional gross anatomy dissection course at McMaster University. Attitudes and perceptions of past participants towards interprofessional learning were evaluated, now that they have started working with other healthcare professionals outside of the IPE course setting. Thirty-four past participants who have clinical experience working in interprofessional settings or are currently working in the healthcare field completed a follow-up questionnaire consisting of a modified Readiness for Interprofessional Learning Scale (RIPLS) and open-ended questions. Quantitative analysis revealed a significant decrease in their attitude towards teamwork and collaboration and respect for other health professions, but a significant improvement in their understanding of roles and responsibilities compared to their results immediately after the IPE intervention. Qualitative analysis of open-ended questions revealed several themes such as developing interprofessional competencies, developing relationships, and remembering the strengths of the IPE dissection course. The results of this study indicate that the IPE experience in anatomy was highly valued by the students and that past participants maintain a clear understanding of their scope of practice, but the reality of clinical practice may have eroded gains made in the program.

High-resolution mapping of brain vasculature and its impairment in the hippocampus of Alzheimer's disease mice     

Xiaochuan Zhang  Xianzhen Yin  Jingjing Zhang  Anan Li  Hui Gong  Qingming Luo  Haiyan Zhang  Zhaobing Gao  Hualiang Jiang 《国家科学评论(英文版)》2019,6(6):1223

Accumulating evidence indicates the critical importance of cerebrovascular dysfunction in the pathogenesis of Alzheimer';';s disease (AD). However, systematic comparative studies on the precise brain vasculature of wild-type and AD model mice are still rare. Using an image-optimization method for analysing Micro-Optical Sectioning Tomography (MOST) data, we generated cross-scale whole-brain 3D atlases that cover the entire vascular system from large vessels down to smallest capillaries at submicron resolution, for both wild-type mice and a transgenic (APP/PS1) mouse model of AD. In addition to distinct vascular patterns in different brain regions, we found that the main vessels of the molecular layer of the hippocampal dentate gyrus (DG-ml) undergo abrupt changes in both diameter and branch angle, spreading a unique comb-like pattern of capillaries. By using a quantitative analysis workflow, we identified in the hippocampus of AD mice an overall reduction of the mean vascular diameter, volume fraction and branch angle, with most significant impairment in the DG-ml. In addition, virtual endoscopy revealed irregular morphological features in the vessel lumen of the AD mice, potentially contributing to the impairment of blood flow. Our results demonstrate the capability of high-resolution cross-scale evaluation of brain vasculature and underscore the importance of studying hippocampal microcirculation for understanding AD pathogenesis.  相似文献   

Teachers' Attitudes Toward Technology in a Two-Way Dual-Language Program     

Ricardo González-Carriedo  Pamela Esprívalo Harrell 《学校用计算机》2018,35(2):111-133

This study examined the attitudes of nine teachers in a two-way dual-language program in regard to using technology to support the linguistic and academic development of emergent bilinguals. Using a phenomenological, multiple case-study approach, teachers'; perceptions about using technology in education and the potential of technology to advance the students'; bilingualism and biliteracy were analyzed. Results showed that teachers had a positive outlook about the potential of technology as a tool to support the academic and linguistic growth of the students. However, several significant challenges were identified, most notably among them the scarcity of technological hardware at the school and the shortage of Spanish-language educational resources. The teachers'; perception was that a greater availability of digital technologies, including resources in the Spanish language, would greatly enhance student learning.  相似文献

Enhancing children's literacy skills: designing the Q‐Tales ecosystem for children's e‐book design and publication          下载免费PDF全文

Bonnie Thompson Long  Tony Hall  Michael Hogan  Nikos Papastamatiou 《Literacy》2018,52(3):171-179

This article describes the conceptualisation and development of a pedagogical framework to support the design of e‐books for children to enhance literacy development. It emerged from research undertaken within the Q‐Tales international consortium project of the EU';s Horizon 2020 Programme for Research and Innovation, where the aim was to facilitate key stakeholders to collaborate and participate in the online production and publication of high‐quality, educational e‐books for children. The pedagogical framework described here sought to answer the question “What concepts and principles undergird the effective design of pedagogically impactful e‐books for children?” It is grounded by the theoretical underpinnings of socio‐constructivism, constructionism and skill theory, and how they relate to children';s literacy development. A framework describing different narrative forms and component features, key pedagogical activities appropriate for different stages of reading development and design recommendations regarding the integration of multimedia into e‐books are also central to the pedagogical framework. As well as informing the design of the Q‐Tales infrastructure for children';s e‐book design and publication, we hope the guidelines and pedagogical activities enumerated here will be widely useful for those designing and developing digital, interactive narratives, particularly e‐books to enhance children';s emerging literacy.  相似文献   

Metaphors of knowing,doing and being: Capturing experience in teaching and teacher education     

《Teaching and Teacher Education》2018

In this article, Bateson';s idea of human beings thinking with metaphors and learning through stories is examined as it played out within accumulated educational research studies. Five storied metaphors illuminating knowing, doing and being are highlighted from five investigations involving different research teams. In the cross-case analysis, the importance of narrative exemplars emerges, along with the significance of metaphors serving as proxies for teachers'; experiences. The plotlines of the metaphors, the morals of the metaphors and the truths of the metaphors are also discussed. In the end result, the value of metaphors in surfacing teachers'; embedded, embodied knowledge of experience is affirmed as well as the deftness of the narrative inquiry research method in metaphorically capturing pre-service and inservice teachers'; storied experiences.  相似文献   

Classroom Debates: Using Speed Rounds To Encourage Greater Participation     

Julianne Treme 《College Teaching》2018,66(2):86-87

The primary obstacle that can derail the effectiveness of a debate is one in which few students are involved and all of the energy and learning is limited to a few students. This leaves the majority of students passively absorbing information and does not encourage participation among those students that typically do not talk in class. This quick fix proposes a technique to increase the involvement of all students in the debate.  相似文献   

The social structure of entrepreneurship as a scientific field     

Hans Landström  Gouya Harirchi 《Research Policy》2018,47(3):650-662

Entrepreneurship as a scientific field has grown significantly, irrespective of the measures used. In this article we raise the question: How can we understand the evolution and success of entrepreneurship as a scholarly field? In particular, we focus on the social structure of entrepreneurship scholars to explain (1) how they are becoming integrated into larger scholarly communities and (2) how they differ from the way scholars integrate within the field of innovation studies. Based on a unique database and responses from 870 entrepreneurship scholars, we demonstrate that entrepreneurship can be regarded as a phenomenon-driven field bound together by a shared communication system and social interaction rather than strong theoretical influences, i.e., a social scholarly community. We identify two broader social communities; one embedded in entrepreneurship conferences that includes a rather eclectic group of entrepreneurship scholars, and another related to entrepreneurship journals and entrepreneurship economics, characterized by a stronger domain orientation. In contrast, scholars in innovation studies tend to be more theory-driven and are bound together by their disciplinary and theoretical background, i.e., an intellectual scholarly community.  相似文献   

Supervisor Cultural Humility Predicts Intentional Nondisclosure by Post-Master's Counselors     

Ryan M. Cook  Connie T. Jones  Laura E. Welfare 《Counselor Education & Supervision》2020,59(2):160-167

The authors examined supervisor cultural humility as a predictor of supervisee intentional nondisclosure. Using multiple regression in a sample of 101 post-master';s counselors, the authors found that 20% of supervisees'; intentional nondisclosure was explained by their perceptions of their supervisors'; level of cultural humility.  相似文献
