城市产业模式研究

现代化的大生产从一开始就拥有一种在不断的分工中进行自身繁殖、在空间和规模上不断自我扩张 的成长机制。产业内部不断分工,在城市发展中就表现为不同类型城市产业模式。本文从五个方面阐述了不同类型 产业模式的生成原因和面临的问题。     

A long-term experiment to investigate the relationships between high school students’ perceptions of mobile learning and peer interaction and higher-order thinking tendencies

In this study, a one-year program was conducted to investigate the relationships between students’ perceptions of mobile learning and their tendencies of peer interaction and higher-order thinking in issue-based mobile learning activities. To achieve the research objective, a survey consisting of eight scales, namely, usability, continuity, adaptive content, collaboration, communication, problem-solving, critical thinking and creativity, was developed. A total of 658 students from 38 high schools in Taiwan filled in the questionnaire after experiencing issue-based mobile learning activities. From the exploratory and confirmatory factor analyses, it was found that the questionnaire had high reliability and validity. The structural equation model further revealed that the provision of adaptive content in the mobile learning had positive impacts on the students’ tendency to interact with peers (i.e., collaboration and communication), which further affected their tendency to engage in higher-order thinking (i.e., problem-solving, critical thinking, and creativity). The findings of this study provide a good reference for researchers and school teachers who intend to promote mobile learning in school settings.     

法律保护、控股股东与公司绩效分析

我国上市公司具有典型的股权集中特征,研究控股股东行为对于改善我国公司治理具有重要意义。控制权收益是控股股东最大化自身利益的载体。现实决策中,控股股东往往需要权衡公共收益和私人收益哪一个更有利于实现自身利益最大化。文章从法律保护角度出发,以控制权收益为切入点,构建了一个研究控股股东行为的分析框架。结合我国控股股东的实际情况,将该框架进一步具体化,用来解释我国国有控股公司与民营控股公司的绩效差异之谜。     

农村教师培训需求对高师课程与教学改革的启示

高等师范院校课程与教学改革要与基础教育课程改革相适应,教师培训需求是教师对基础教育课程改革的心理反映。对农村教师培训需求的调查发现,高师课程与教学改革应该完善教育专业课程体系建设,增加教师技能训练课程门类;加强教育专业课程内容改革,突显课程内容的时代性和实用性;转变学习方式,突出学生主体性教学;关注学习过程,注重形成性评价。     

基于远程学习者个体需求的教学策略探究

远程教学是建立在信息技术和学习者学习需求基础上的教学,在具体的教学过程中采用什么样的教学策略,不仅要看技术条件和学科特点,更重要的是要看学习者的实际需求。本文在分析了远程学习者特征和学习需求的基础上,着力探讨了网络环境下基于学习者个体需求的教学策略。在宏观上提出了三种比较可行的教学策略,即资源性教学策略、非系统性教学策略和服务性教学策略。     

“自愿问责制”:美国高等教育问责制发展的新动向

近年来,"自愿问责制"(VSA)的兴起为美国公立学院和大学改革注入了新的活力,反映了美国公立院校领导层应对新挑战的基本思考。"大学肖像"模板是"自愿问责制"的主要实现形式,包含学生与家庭信息、学生经历与体会以及学生学习结果三个截面的内容,体现了整合性与集约化并举、规范化与弹性结合、创造性与渐进性兼顾等特点。虽然"自愿问责制"的发展伴随着质疑且存在一些有待解决的难题,但其发展对美国高等教育产生了重要影响。     

The Importance of Teaching and Learning Nature of Science in the Early Childhood Years

Though research has shown that students do not have adequate understandings of nature of science (NOS) by the time they exit high school, there is also evidence that they have not received NOS instruction that would enable them to develop such understandings. How early is “too early” to teach and learn NOS? Are students, particularly young students, not capable of learning NOS due to developmental unreadiness? Or would young children be capable of learning about NOS through appropriate instruction? Young children (Kindergarten through third grade) were interviewed and taught about NOS in a variety of contexts (informal, suburban, and urban) using similar teaching strategies that have been found effective at teaching about NOS with older students. These teaching strategies included explicit decontextualized and contextualized NOS instruction, through the use of children’s literature, debriefings of science lessons, embedded written NOS assessments, and guided inquiries. In each context the researchers interviewed students prior to and after instruction, videotaped science instruction and maintained researcher logs and field notes, collected lesson plans, and copies of student work. The researchers found that in each setting young children did improve their understandings of NOS. Across contexts there were similar understandings of NOS aspects prior to instruction, as well as after instruction. There were also several differences evident across contexts, and across grade levels. However, it is clear that students as young as kindergarten are developmentally capable of conceptualizing NOS when it is taught to them. The authors make recommendations for teaching NOS to young children, and for future studies that explore learning progressions of NOS aspects as students proceed through school.     

学术型硕士研究生教育质量管理体系构建研究

学术型硕士研究生教育质量的提高依赖于研究生教育质量管理体系中各要素质量的提高。将优越的管理体系作用于高质量的体系要素并形成优化的结构,学术型硕士研究生教育质量水平在整体上可以获得提高。2008版ISO9001标准可以指导学术型硕士研究生教育质量管理体系的构建。将ISO9001标准引入研究生教育领域,会使更多的培养单位获得更多的发展机遇,提高教育质量,提高教育管理水平。     

语篇隐喻的隐喻化过程及其分类

自从韩礼德第一次系统地提出语法隐喻理论以来,语法隐喻受到越来越多的关注。作为一个相对较新的理论,语法隐喻仍然有很多不完善之处。其中,语篇隐喻就是一个典型的例子。作为系统功能语言学派最杰出的代表,韩礼德几乎从没有明确地谈论过语篇隐喻,他也没有把语篇隐喻纳入到语法隐喻的系统当中。然而,许多对语篇隐喻感兴趣的语言学家一致认为：除了概念隐喻和情态隐喻之外,语篇隐喻也应该被包含在语法隐喻系统之中。基于韩礼德的一致性理论和意义进化理论,作者建立了语篇隐喻的隐喻化过程的综合模式,该模式表明语篇隐喻的隐喻化过程包含两个过程：语篇化过程和隐喻化过程。     

高职家庭经济困难学生认定中存在问题的思考

对家庭经济困难学生进行资助是我国一项重大决策。贫困生的认定、评议是否合理,影响到国家资助政策落实的公平性和真实性。为此,应加强各级政府的管理,增强高职学院辅导员的工作责任心,构建社会诚信体系,使国家资助款项真正用在家庭经济困难的学生身上。
