Assessment and student participation: ‘choice and voice’ in school principal accounts of schooling territories

Schooling territories are bounded spaces where policies, bodies, practices, and discourses meet and collide. It is well documented in assessment literature that students who are active decision-makers understand their learning processes and have the necessary wherewithal to access support across schooling spaces. These spaces are co-produced through interrelationships, where youth participation is associated with power, voice, democratic citizenship, legal entitlement, empowerment, motivation and self-confidence. Recognising the growing pedagogical emphasis on locating students as responsible for their own learning, we consider how assessment practices constitute enabling and constraining schooling territories. Assessment for learning (AfL) can be linked with emancipatory practices in schooling territories where learner agency is co-produced through socio-material classroom relations. We use principal comments to map a range of interrelated schooling territories as a relational cartography of spatialised practices and student participation in AfL. Mostly, these territories are teacher imagined and defined, constructed through schooling and policy frameworks, and determined through the use of student achievement and student voice data. These conceptualised schooling spaces are interrogated to consider the positionality of students within AfL-related territories. While choice and participation may seem emancipatory, we reveal that AfL practices can serve a rarely acknowledged process of affirming territorial power.     

园林艺术的空间思维意识——论萧红小说的空间形式

萧红小说有两个重要特点:(1)在小说时空处理方面,其小说运用园林空间思维对形象按其同一性并置在一起,使读者在阅读中产生多层次、多样化的美感效果。(2)其小说在借鉴其他艺术方面也有独到之处。它借鉴园林艺术的编排技巧,编排形象和场景,使读者在阅读过程中获得多层次、多样化的感受。这些特点奠定了她在文学史上的地位。     

实现ArcGIS环境下的确认性空间数据分析功能

在地理信息科学领域,空间分析扮演着中心的作用.但目前的地理信息系统商业软件中,空间分析功能仍是一个薄弱环节;即便是美国ESR I公司的ArcGIS,其空间分析模块也仅仅局限于探索性空间数据分析的功能,从而极大地限制了地理信息系统作为空间决策支持平台的作用.本研究的目标便是解决这一问题.我们经过反复实践实现了ArcGIS环境下的确认性空间数据分析功能,包括古典线性回归模型和空间计量经济学模型的标准诊断、估计、以及可靠性检测的复杂算法.通过对ArcGIS的二次开发,真正实现了地理信息系统和空间分析功能的全面集成.     

Spatializing a global education phenomenon: private tutoring and mobility theory in Cambodia

ABSTRACT

Along with the dramatic expansion of private tutoring around the world, a significant body of literature has been produced to understand this phenomenon. While many studies consider the issue of geographic location, the spatial dimension tends not to be a central focus of private tutoring studies. In contrast, the present essay applies mobility theory to research from Cambodia, where private tutoring is essential to student success. It does so in order to place private tutoring provision into a broader perspective that includes but moves beyond the economic dimensions of supply and demand and the sociological dimensions of economic, cultural, and social capital to include consideration of how private tutoring provision is constrained by a multidimensional spatial field of possibilities and how private tutoring participation is enabled by one’s position and abilities in relation to that field. The paper argues for increased attention to ‘spatial capital’ in studies of private tutoring and education generally.     

强非局域介质中超高斯型光束的传输特性

运用变分法研究了傍轴超高斯型光束在强非局域非线性介质中的传输特性,得到了傍轴超高斯型光束各参量的近似演化方程、一个势函数以及一个临界功率;求出了傍轴超高斯型光束各参量的近似演化表达式;并通过分析得到当初始功率等于临界功率时,可以获得稳定的超高斯型空间光孤子;对于一般情形,傍轴超高斯型光束束宽则作周期性的压缩或展宽变化.

汉语语言形式中的民族时空观--汉语时间表达中的空间隐喻

认知语言学认为时间概念是由空间概念隐喻而来，“自我在动／时间在动”的空间隐喻是许多语言所共有的。文章以汉语时间表达的空间隐喻为语料，发现汉语较多使用“时间在动”的隐喻，为这一普遍性提供了佐证。同时发现“自我在动／时间在动”的隐喻不能完全解决汉语中一些时间表达的矛盾。
