生物学是一门以实验为基础的自然科学，观察和实验是生物科学研究的重要方法，是学生获取感性知识的重要源泉，是实施素质教育的良好切人点。在高中生物教学中，实验占有极为重要的地位。对实验能力进行考查是当前高考的重要内容之一。由于考查学生的实验操作技能目前还难以实现，因此考查的内容主要集中在实验原理、实验目的、材料用具、方法步骤、操作要领等方面，以及对实验程序、实验现象、实验结论的分析、归纳和总结及进行简单的实验设计。高考所考查的生物实验，并不局限于生物教材上所提及的常规实验，而是在常规实验的基础上，利用新教材，借助新情景进行创新实验设计，解决和探索新的问题。 相似文献

A resurgence of national and international interest in citizenship education, citizenship and social cohesion has been coupled with an apparent emergence of a language of crisis (Sears & Hyslop-Margison, 2006). Given this background, how can or should one consider a subjective sense of membership in a single political community? What this article hopes to show is that confining the subject of citizenship or patriotism to a national framework is inadequate in as much as there are grounds to argue for a more expansive and, at the same time, integrated outlook. Patriotism, like Citizenship, is still open to interpretation and potentially in danger of falling short of a richer conception. Education, therefore, needs to incorporate inclusive practices and encourage an integrative mindset in order to accommodate: increasingly complex identities, associations, experiences and continuing changes in the political landscape. In this article, the author argues for the importance of learning ways in which to value and respect diversity while working towards a principle of unity in diversity. Cultivating a subjective sense of membership in a single world polity is vital in matters pertaining to sustainability and justice.
In response to considering possible ways of sharing a subjective sense of membership in a single community and some implications for Citizenship, Patriotism and Citizenship Education, this article looks to three areas: ways in which to understand the notion of citizenship and patriotism, cultural crises and the notion of a cosmopolitan nation and, finally, the personal dimension to education for world citizenship. 相似文献

This study aimed to use a learning inventory (the Approaches and Study Skills Inventory for Students, ASSIST) to measure the
impact of a curriculum change on students’ approaches to learning in two large courses in a health sciences first year programme.
The two new Human Body Systems (HUBS) courses were designed to encourage students to take a deep approach to learning. ASSIST
was completed by 599 students enrolled in a biology class in 2006 that was part of the old curriculum, and by 705 students
at the beginning and end of the new HUBS courses in 2007. Changes in students’ approaches to learning over time were examined.
The ASSIST scores for both HUBS courses reflected the dominance of a surface approach, followed by a strategic and then a
deep approach. However, by the end of the year, students were taking a deep and strategic approach to their studies to a greater
extent, and a surface approach to a lesser extent. Moreover, students enrolled in the new course adopted a deep approach to
their studies to a significantly greater degree than those studying the old curriculum. Despite the predominance of a surface
approach, the results suggest that it is possible to bring about small but significant positive changes in students’ learning
behaviour in a very large class through curriculum change. The proportion of students preferring a surface approach, and results
showing that high performance on the final exam was significantly correlated with a surface approach, probably reflected contextual
factors, including assessment, and is the focus of ongoing curriculum development. 相似文献

诠释学作为一门指导文本理解和解释的学科，在以前类似于修辞学、语法学、逻辑学，从属于语文学。到了20世纪，诠释学由一种理解和解释的方法论发展成为一种哲学理论。诠释学的哲学转向与世界意义的多元化转向并行。随着古典诠释学向现代哲学诠释学的转换，诠释学不再仅是对经典文本的诠释而具有多元化的意义，从而为自己找到广阔的诠释空间，因此在诠释学的视野下比较诗学也具有更加开放的被诠释可能。以诠释学为背景，进一步探讨比较诗学在学理意义上的可能性和可行性，便会发现：比较诗学之“比较”不是工具论意义上的一种手段而是存在论意义上的一种思维方式，从而为比较诗学学科研究提供一个新的视角。 相似文献

To compare the metaphorical views of elementary and secondary school environments, as recalled by American and Chinese college students preparing to become teachers, preferred and actual school experiences were related to metaphors, such as being in a crowd, in a prison, on a team, or in a family. The analysis of data revealed that American elementary schools were most often compared to being in a family and secondary schools to being on a team. Hong Kong students, on the other hand, compared elementary schools to being on a team and secondary schools to being in a family. 相似文献

Two studies were undertaken to assess the value of exposing people to performance visualization in order to help them cope with communication apprehension (CA) in employment interviews. The first study, which took place in a laboratory, employed a pre/post‐test experimental design. Seniors who were preparing to enter the job market took part in mock interviews, completed a state communication apprehension (CA) measure, a trait CA measure, and a scale designed to measure negative thinking. Participants were then assigned to performance visualization, placebo, or control conditions. After exposure to the requisite treatment, they participated in another mock interview and completed the same battery of measures. The second study took place in the field. In this study, participants, who were about to undergo a screening interview for a job, completed state and trait CA measures, were exposed to performance visualization, and completed the state and trait CA measures the second time. These studies indicated that exposure to performance visualization related negatively to CA and negative thoughts, as well as positively to being offered a job. It showed no relationship to being asked back for a second interview. The implications of these findings are discussed in the conclusion of this report. 相似文献

This paper has a limited purpose. It does not pretend to present a rigorously argued position. Rather it represents, in part, an attempt to indicate in brief outline a way in which some ideas developed in what could broadly be termed ‘the existentialist tradition’ might be brought to bear on a topic of current interest in educational theorising. This will take the form of a sketch of a critique of a currently fashionable view on the topic to be considered. But, to reiterate, what follows is a sketch, only. 相似文献

This study explores pre-service teachers’ perceptions of movement education, the benefits they perceive from participating in a 12-week movement education module in a course on play, and the module’s effects on their confidence and competence in regard to incorporating movement into a curriculum. Findings suggest that the pre-service teachers achieved a deeper understanding of movement education and appreciated the module as a worthwhile professional growth experience. Specifically, they viewed the module as enabling them to build a new understanding of movement, to express themselves physically, to develop movement skills, to engage in social interactions, and to teach a variety of subjects using movement education principles. The study demonstrated that the module of this nature constitutes a useful educational tool for fostering the professional development of pre-service teachers in regard to their beliefs, attitudes, and skills pertaining to movement education. 相似文献

This article discusses English language teaching in Thailand through a biographical case study of a teacher working in a government school in the rural north-east. It explores a particular context of teaching and learning, showing how an individual comes to be a teacher and deals with the day-to-day demands of teaching, as well as reflecting on the place of English in a society where it is a foreign language. The article contends that case studies of this type have the power to illuminate the context of teaching, to enable us to come to a fuller understanding of the demands of being a teacher of English in societies where it is a foreign language, and thus to provide essential data on the realities of teaching in various contexts. This data may then be used to inform centralized programmes to reform English language teaching which at present rarely consult the principal change agents – teachers – prior to their implementation. Curriculum reform programmes in Thailand have been criticized for their lack of impact at the classroom level and the article maintains that, if these programmes are to be effective, they should be based on an understanding of the local contexts of teachers' work. 相似文献
