全球经济一体化的发展趋势,使得全球各个国家之间的交流也日益增多,英语作为一门国际语言,在各个国家交流中起着桥梁的作用。提高英语口语水准和交际水平成为当今全球各个国家交流中的首要任务。目前,国内各个高等院校关于英语专业和非英语专业,也增加了学生英语口语测试。这也证明了,在国内各个高校英语课程改革的过程中,英语口语教学也成为了当下非常重要的内容之一。  相似文献

课文层次结构的教学,不仅要引争学生理清这篇文章的结构层次,更重要的是通过这篇文章的层次结构分析,引导学生把握层次结构分析的某种理由或依据,进而获得某种层次结构分析的方法。分析文章的层次结构,当然需要理解文章各个段落、各个部分的意思,考察各个段落、各个部分意思之间的内在联系;但同时,各个段落、各个部分之间语文形式上的联系,也是分析文章层次结构时不可忽视的重要的依据,因为这些语文形式正是作者用来显示和加强内容联系的结构标记,尤其是在议论文之中。  相似文献

历史上各个时期各个地区统治者获得公共权力之后便要运用各种手段对其掌握的公共权力的合法性进行论证.公民是公共权力的合法性的唯一来源,处于不同的经济基础之下的公民,对当权者的诉求必然不同,从而在各个不同时期、各种社会形态下的公共权力合法性呈现一个演进的状态.文章通过对各个不同形态的公共权力合法性的梳理,揭示了公共权力合法性的演进逻辑.  相似文献

Conclusion The Strategic Impact Model is distinctive in its portrayal of the integration of instructional and non-instructional interventions and its suggestion that all performance interventions undergo an analysis-design-development-production cycle, just as instruction does. It also differs from other similar models in its use of evaluative activities at each stage to assure alignment with strategic needs as well as quality control, and its suggestions for improving the chances of successful implementation by carrying out change management activities at each phase of the development process. He has special interests in distance education, historical and philosophical foundations of instructional technology and instructional development processes. He has special interests in planning and evaluating performance improvement initiatives, including training. An erratum to this article is available at .  相似文献

Conceptual design plays an important role in product life cycle, which requires engineers to use sound design theory, cross-disciplinary knowledge, and complex technical support to acquire design concepts. However, the lack of sufficient computational tools makes it difficult for designers to fully explore in the wide design solution spaces. Therefore, this paper proposes an integrated cognitive computing approach to formalize the cognitive activities of conceptual design. A cognitive computing model composed of concept associative memory, concept generation, and decision-making process is established based on the integration of cognitive psychology and engineering design. First of all, the Hopfield neural network is used to acquire similar concept solutions for specific subfunctions from a knowledge base. Then, morphological matrix and genetic algorithm are introduced to produce a set of feasible candidate solutions in the concept generation process. Furthermore, a technique for order preference by similarity to an ideal solution is applied to evaluate the generated concept solutions and obtain the optimal solution automatically. Finally, a case study is given to demonstrate the effectiveness and efficiency of the proposed approach.  相似文献

This study is designed to investigate the impact of school‐based curriculum development teams on teacher development within the tradition of school‐based curriculum development in a primary school in Hong Kong. Teacher interviews were used to evaluate the extent that teacher engagement in curriculum decision‐making processes within two school‐based curriculum development teams has led to teacher professional development which were triangulated with the videotaped meetings and tryout lessons. Qualitative evidence has revealed positively that participating teachers have developed themselves professionally through the process of planning, experimenting and reflecting (PER model) upon curriculum practice and innovation under certain conditions. However, the complexity of the structures and processes that were established for involving teachers in curriculum decision‐making processes needs further empirical and theoretical work. This paper only looks at data relating to teacher development in curriculum leadership collected in the second action cycle of the project from January to June 2005.  相似文献
