探讨翻转课堂在检验医学教育中的应用

翻转课堂(ICM,inverted classroom model)是在多媒体快速发展的基础上建立起来的一种融合多种学习方法的混合性教学方法。在课堂之前,借助网络、微课、期刊等多种途径制作辅助材料,并让学生通过使用这些材料接触和自学教学内容包含的基础知识;课堂中通过师生互动,积极提出疑问、剖析讨论、探究解决问题;课后通过各种测试反馈学生在本次课程中的表现,同时对教学活动进行评价。成功的翻转课堂应具有以下几个目标:(1)提高学生学习主观能动性,快速掌握基础知识;(2)学生和教师充分互动交流;(3)刺激学生更深入掌握辅助资料中的知识;(4)培养学生的批判性思维;(5)提高学生分析、综合以及评价等能力。我国医学教育结构复杂,各个领域相互关联,单一的教学模式不能满足当前的教学要求。电子产品、电子书籍、期刊、小视频普遍使用,以及大量公开的教育资源为翻转课堂的教学模式完善提供更多的途径,如何更有效的应用翻转课堂是各专家们关注的焦点。     

Shifting discourses in teacher education: Performing the advocate bilingual teacher

ABSTRACT

This article analyses the co-construction of the Bilingual teacher as advocate among preservice Bilingual teachers, through the use of narratives drawn from actual stories of Bilingual teachers, by means of drama-based pedagogy inspired by Theater of the Oppressed techniques. This study uses critical discourse analysis and Bakhtinian intertextuality to analyze how preservice Bilingual teachers shifted the discourse, moving from discussing issues pertaining to Bilingual education, such as race and immigration, from the outside to from the middle, situating themselves as protagonists of the conflict. The improvisational nature of the performances, owing to the use of drama-based techniques, allowed the participants to explore critical issues, develop their stance toward issues of immigration and racism, and rehearse their identities as advocates.     

Why music matters in urban school districts: The perspectives of students and parents of the Celia Cruz High School of Music,Bronx, New York

Despite their long history and importance in the American curriculum, music programs must constantly justify their place in the twenty-first century. Urban areas that are economically depressed sometimes may not be able to offer music instruction due to the emphasis on raising test scores as well as unfavorable economic conditions that may limit their options. Despite these challenges, community leaders and educators successfully established a school of music in the Bronx, New York. Celia Cruz High School, the focus of this case study, was created to offer a musically centered curriculum in the borough of the Bronx as well as address the epidemic of large failing schools. Celia Cruz in its design and current state serves the population of the Bronx and reflects that demographic. Interviews with parents and students were carried out as a means of establishing the perspective of a musically focused education within this context. Based on interviews, parents and students of Celia Cruz value music as its own form of knowledge and view it as a vital part of the academic lives of the students of Celia Cruz High School. The purpose of this study was to share the stories, perspectives, and experiences of the Celia Cruz community and the impact that a musically focused education could have on the lives of students in the Bronx, New York.     

Assessing Effectiveness of a Nonhuman Animal Welfare Education Program for Primary School Children

Nonhuman animal welfare education aims to promote positive relationships between children and animals and thus improve animal welfare, yet few scientific evaluations of these programs exist. This study aimed to evaluate the effectiveness of an education program developed by the Scottish Society for the Prevention of Cruelty to Animals (SPCA) that included 4 interventions focusing on pets (companion animals), wild animals, farm animals, and general animal rescues. Knowledge, attachment to pets, and attitudes and beliefs about animal minds were assessed at pretest, posttest, and delayed posttest using a questionnaire administered to 1,217 Scottish children aged 7 to 13 years old. Results showed a significant positive impact of the program on knowledge about animals and the Scottish SPCA for all interventions. The pet and farming interventions significantly impacted children’s beliefs about animal minds. There were trends toward improvements in a range of other measures. This study highlights the importance of teaching animal welfare education to children for early prevention of animal cruelty, discusses the need to base this education on theory and research to find effective change, and demonstrates how evidence-based practice can inform future education programs.     

日本演习林制度对中国生物多样性保护与国家公园建设的启示

演习林是日本通过农林院校管辖和运行的自然林地与人工林, 兼具科教、生物多样性保护、生态旅游与林木生产等功能。演习林的责、权、利明确, 能够实现长期、稳定的保护与利用, 与自然保护区、国家公园既有区别又相辅相成, 是日本经济协调发展与快速实现生态恢复的一个重要保障。目前, 日本约有30所高等院校拥有演习林, 演习林面积约占日本森林总面积的5‰, 其中东京大学的演习林建立最早、运行与管理机制最为完善。演习林主要有三大功能: 教学实践、科学研究、社会服务。演习林主要负责人是大学教师, 教师既参与科教也参与管理, 实现了教授治校、科教与社会服务的协调发展。当前, 我国正处于生物多样性保护的转型期和国家公园试点建设的关键阶段, 农林类高校或研究所可借鉴日本演习林制度, 主动参与到国家“绿水青山就是金山银山”的绿色发展理念和实践中; 涉及生物学与农林学科的科学工作者应积极承担当地自然保护区、森林公园、国家公园等的建设与管护。政府可以引导和吸纳有着充足研究经费、学术水平较高的农林与生物学类高校(特别是相关学科被列入“世界一流学科”建设行列的高校)在有条件的自然保护区或城市周边开辟高校直辖林地, 实现教学实践、研究与保护、社会服务等共建共存模式, 提升我国高校农林与生物学科研究水平, 促进我国生物多样性的可持续保护和国家公园的高标准建设。     

Precaution in Practice

Voluntary initiatives by industry have been frequently proposed as one of the most promising ways to reduce potential negative impacts on human health and the environment from nanomaterials. In this study, we examined the industrial perceptions, internal procedures, and performance of the nanomaterial industry. We conducted a written survey of 40 companies in Switzerland and Germany. Most companies replied that nanoparticulate materials (NPMs) should be subject to some kind of regulation, but industry did not convey a clear opinion as to who should be responsible for managing the potential environmental health impacts or how to regulate NPMs throughout their life cycle. If NPM risks were to be identified, most of the companies surveyed do not have standardized procedures for changing production technology, substituting inputs, redesigning processes, or reformulating final products to reduce or eliminate risks of NPMs. However, a majority of the survey respondents found their existing routines regarding these procedures to be sufficient.     

The changing status of the Chalkhill Blue butterfly <Emphasis Type="Italic">Polyommatus coridon</Emphasis> in the UK: the impacts of conservation policies and environmental factors

The Chalkhill Blue Polyommatus coridon is a widespread butterfly of lowland calcareous grassland in southern Britain and is considered a good indicator of habitat condition. Polyommatus coridon has been identified as a Species of Conservation Concern in the UK Biodiversity Action Plan due to a greater than 25% decline in range size since the 1950s, with losses due to the combined effects of habitat destruction, agricultural intensification and neglect. Analysis of annual butterfly monitoring data (transects) collected at 161 sites from 1981 to 2000 show a three-fold population recovery had occurred. The increases were at established sites, with no re-colonisations or range expansion detected. The 1980s population increase coincided with increases across the species range in stock and rabbit Oryctolagus cuniculus grazing, as well as greater protection and management of sites through protected areas and nature reserves. During the 1990s agri-environment schemes were thought to be the main conservation and policy mechanism driving the favourable conservation status of P. coridon, by facilitating appropriate habitat restoration and management. Weather played a part in the species recovery, with warm, but wet summers associated with increases in abundance. The research provides strong evidence of an important conservation success with the UK Biodiversity Action Plan, with implications for other specialist biodiversity.
