我国区域人文社科类高校知识传播效率差异及收敛性研究     

程慧平 《高等理科教育》2016,(1):60-66

文章使用DEA-Dagum基尼系数—收敛性检验方法,依据2009—2013年31个省份的面板数据测量我国人文社科类高校知识传播效率,分析区域差距及其收敛性.研究显示:东、中、西部地区知识传播效率依次递增.我国人文社科类高校知识传播效率低下受规模效率和纯技术效率低下的双重影响,纯技术效率低下影响更大.大部分省份处于规模报酬收益递减状态,区域内差距是全国整体效率差异的主要原因.全国及三大地区人文社科类高校知识传播效率差距均存在不同类型的收敛.  相似文献   

Developmental discourses as a regime of truth in research with primary school students     

Clare Bartholomaeus 《International journal of qualitative studies in education》2016,29(7):911-924

While developmental discourses have been heavily critiqued in relation to education systems, less attention has been paid to how these impact the data collection process in classroom research. This article utilises Foucault’s concept of regime of truth to highlight the pervasiveness of developmental discourses when conducting research in primary schools. Such a theoretical framing makes explicit how developmental discourses work and are constructed as ‘truth’, which limit the possibilities for alternative perspectives. This article shows how this regime of truth works in practice by reflecting on qualitative research conducted with two age groups in two primary schools in Australia, focusing on the researcher’s navigations of these discourses. In particular, this article examines the impact of developmental discourses on conducting research with multiple age groups, initiating research, choosing methods for data collection, and negotiating power relations and ethical practices.  相似文献

Mathematical Modeling in the Primary School: Children's Construction of a Consumer Guide     

Lyn D. English 《Educational Studies in Mathematics》2006,63(3):303-323

This paper examines 6th grade children's local conceptual development and mathematization processes as they worked a comprehensive mathematical modeling problem (creating a consumer guide for deciding the best snack chip) over several class periods. The children and their teachers were participating in a 3-year longitudinal teaching experiment in which sequences of mathematical modeling problems were implemented from the 5th grade (10 years of age) though to the 7th grade. In contrast to traditional problem solving, mathematical modeling requires children to generate and develop their own mathematical ideas and processes, and to form systems of relationships that are generalizable and reusable. Reported here is a detailed analysis of the iterative cycles of development of one group of children as they worked the problem, followed by a summary of the mathematization processes displayed by all groups. Children's critical reflections on their models are also reported. The results show how children can independently develop constructs and processes through meaningful problem solving. Children's development included creating systems for operationally defining constructs; selecting, categorizing, and ranking factors; quantifying quantitative and qualitative data; and transforming quantities.  相似文献
