用水壶烧水既快又方便,可头疼的是冲水时,歪倒的水壶把被炉火烘得很烫,手不能直接握住它,得到处找抹布把它包着,这样极不方便。我发现水壶把烫手的主要原因是:水壶把易歪倒,被炉火烘热,只要在水壶烧水时,将水壶把直立,水壶把就不会烫 相似文献

唐朝时，南方官吏缅伯高受太守委托，向皇上进贡天鹅。途经沔阳时，缅伯高发现天鹅身上有灰土，就将天鹅解下给它洗澡。谁知不趁让天鹅飞走了，缅伯高伸手只抓住了两根鹅毛。丢了贡品可有杀头之罪啊!缅伯高吓得倒在地上哀哀号哭。哭了一阵，无奈只得带上鹅毛进京。到了京城，缅伯高看见别的使者的贡品都十分珍贵，心里很难受，却又一筹莫展。轮到他进贡了，他恭恭敬敬地呈上鹅毛，同时吟了一首诗。 相似文献

我们小时候踢毽子,毽子都是自己做的。选两个小钱(制钱),大小厚薄相等,轻重合适,叠在一起,用布缝实,这便是毽子托。在毽托一面,缝一截鹅毛管,在鹅毛管中插上鸡毛,便是一只毽子。鹅毛管不易得,把鸡毛直接缝在毽托上,把鸡毛根部 相似文献

案例教学:谋求教学理论与教学实践协同提升 总被引：6，自引：0，他引：6
传统的教师教育面临着无法切实沟通和有效整合教学理论与教学实践的困境，而案例教学则让人们看到走出这一困境的希望。由于运用于教师教育的案例教学是以讨论对话、集体合作、批判反思、理论实践协同提升、教师和学员共同发展为基本取向，因此，为切实沟通和有效地整合教学理论与教学实践，案例教学必须发挥以下基本功能：激活与展现教学实践智慧、解构与重构课堂教学实践、显化与提炼教学理论知识、直面与聚焦课程教学改革。 相似文献

Mental health difficulties affect 1 in 10 children and adolescents, and up to half of adult cases begin during the school years. The individual and societal impacts of such difficulties are huge, and include poorer quality of life, lost economic productivity, destabilisation of communities, and high rates of health, education and social care service utilisation. Using early intervention and prevention in schools as a central component of a co-ordinated response to this emergent public health crisis makes good sense. Schools play a central role in the lives of children and their families, and their reach is unparalleled. It has been argued that truly comprehensive and effective mental health promotion in schools requires a universal screening component, but this is a controversial proposition. In this article we explore some of the opportunities and challenges posed by such a system. In doing so, we critically assess international literature on social validity (e.g. acceptability, feasibility and utility), definition and conceptualisation (e.g. what do we mean by ‘mental health’ and related terms?), design and implementation (e.g. planning, tool selection, linking to referral and intervention systems), psychometric considerations (e.g. are available instruments reliable and valid?), diversity (e.g. taking into account cultural variation) and costs and benefits (e.g. are the human, financial and material costs of universal screening justified by the improvements in provision and outcomes they bring?). We conclude by presenting a vision for a school-based system that takes into account these important factors. 相似文献

Anatomical fixation and conservation are required to prevent specimens from undergoing autolysis and decomposition. While fixation is the primary arrest of the structures responsible for autolysis and decomposition, conservation preserves the state of fixation. Although commonly used, formaldehyde has been classified as carcinogenic to humans. For this reason, an adequate substitute was developed. Ethanol-glycerin fixation and thymol conservation are described and compared with formaldehyde and phenol in this technical report. The setup, tissue qualities, financial aspects, and health concerns of this method are discussed. Ethanol-glycerin fixation and thymol conservation provide outstanding haptic and optic tissue qualities. Typical formaldehyde and phenol effects, such as skin, airway, and eye irritation, as well as carcinogenic effects, can be circumvented by using ethanol-glycerin and thymol instead. Ethanol-glycerin fixation is more expensive than formaldehyde and requires an explosion-proof facility. However, the absence of health effects and its convincing tissue qualities balance these higher costs. Therefore, ethanol-glycerin fixation and thymol conservation provide a potential alternative and complement established fixation techniques. The use of carcinogenic formaldehyde and toxic phenol can be effectively restricted through the use of the described method. 相似文献

We analyse two narratives of teacher‐facilitator teams producing elementary science curricula and disseminating them to their peers. We draw on these stories to interpret how teacher‐facilitators position themselves with respect to other educators (e.g. peer teachers and development‐team members), to real and imagined students and parents, to knowing and learning science, and to pedagogical practices and texts. We read these acts of positioning relationally and responsively. Teacher‐facilitators position themselves and their work in highly complex ways to multiple political and social others. These multiple positions raise a range of anxieties and questions for the teacher‐facilitators and shape their curricular and leadership roles. Our purpose is, first, to tease out these complexities of positioning and subjectivity, and second, to consider how teachers construct their roles as pedagogical and curricular leaders among their peers. This analysis illuminates thinking about how reform is enacted in schools and how leadership roles are constructed. 相似文献
