关于Tfg—遗传环、Tfg—正则环   总被引:1,自引:0,他引:1  
本文借助于左酉模范畴R1M中的遗传扭论(T,F)相对应的Gabriel拓扑G,定义并讨论了较平坦模,T-内射模[1、2]、f-内射模[3]、p-内射模[13]更为一般的Tfg-平坦模和Tfg-内射模,然后利用这两类模刻划了Tfg-遗传环和Tfg-正则环,见定理8、9、10和11,从而推广了遗传环和正则环t1-半单环[6]。  相似文献

“互文性”是语篇的基本特征。任何语篇都是由引语拼凑而成,任何语篇都是对其它语篇的吸收和改造。“模因”是文化信息的基本单位。模因的复制、模仿和传播才使得文化得以传播、继承和发展。文章探讨了互文性和模因的关系,指出模因的传播就是互文性形成的过程,并从模因的角度分析了广告语篇中的互文现象,以加深对广告语篇中模因的认识。  相似文献

环上的自由模是域上线性空间的一种推广,因而线性空间的许多性质可以自然地推广到环上的自由模.文[1]指出,交换环上自由模的基所含元素的个数是自由模的一个不变量,即基元个数不变性.这里对任意环上自由模的基及相关矩阵进行了讨论,给出了任意环上两个自由模R^(m)与R^(n)同构的充要条件,R^(m),R^(n)分别是秩为m,n的自由R-模,并且Hom(R^(m),R^(n))是秩为mn的自由R-模,同时做出了使R^(m)≌R^(n)、但m=n不成立的反例.  相似文献

大学专业课程双语教学有助于学生在掌握专业知识的同时,巩固和提升外语应用能力。目前可供选择的双语教学模式很多,国外常见的主要有:沉浸型模式、维特型模式和过渡型模式等;而国内主要有:翻译型模式、渗透型模式、穿插型模式、半外——混合——全外型模式等。双语教学模式的选择应根据各校自身的条件,选择适当的模式,并可从语言目标、学术目标、文化与社会目标几方面进行评价。  相似文献

The following research delivered a web-based module about plagiarism and paraphrasing to avoid plagiarism in both a blended method, with live instruction paired with web presentation for 105 students, and a separate web-only method for 22 other students. Participants were graduates and undergraduates preparing to become teachers, the majority of whom were pursuing certification in elementary education. After the module, students practised paraphrasing with their own written example, then took a Likert-scale survey about their perceptions of the module and provided demographic information. The majority of students expressed a high level of satisfaction with not only the module itself but also their own increased knowledge about paraphrasing and plagiarism. Graduate students and students in the live group felt that pairing an instructor with the module furthered their understanding of paraphrasing. Students who identified themselves as having cheated felt that they had better learned how to paraphrase from the module compared with students who reported themselves as never having cheated. Responses from the web group were low considering the amount of students invited to participate. Students in the live group who had instructor-led discussion felt it contributed to their understanding of paraphrasing, while students in the web group wished for more instructor-led interaction. Outcomes on the student-written paraphrase were weaker than anticipated, with only half of the group producing good or excellent paraphrases.  相似文献

在线学习是一种师生分离的自主学习,对学习者的学习行为进行监控,能提高在线学习效率。利用电子学档对学习者的在线学习行为进行监控,不仅有助于促进学习者的学习反思、激发学习动机、开展更为有效的学习,而且有助于实现对学习者学习行为的全面监控。基于电子学档的在线学习行为监控模型一般包括行为信息的提取模块,整理和分析模块,成果及评价模块,反思模块,行为标准制定模块等五部分。采用这个模型,可以实现对在线学习行为的全面监控。  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 paper describes a module provided to first year elementary participants in a two-year after-degree Bachelor of Education program. The module was specifically designed to address the fact that pre-service teachers can enter the B.Ed. degree with little or no science knowledge. Science experiences were explicitly incorporated into the B.Ed. module described here linking science content knowledge to specific science pedagogic content knowledge. The pre-service teachers were surveyed and interviewed during and after completion of the module. It was found that the inquiry based approach increased the pre-service teachers' level of science knowledge, their confidence with regard to teaching elementary science, and improved their attitude toward science teaching and learning.  相似文献
