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

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.

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

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.

用Javabean构建数据过滤的Script代码生成器

针对asp或jsp的客户端数据过滤程序代码由手工编写,编程效率低的缺点,提出了用脚本代码生成器实现自动生成数据过滤代码的方法。生成器的主要组件是Javabean,它可以连接到不同的数据库并操作数据表,在提取数据表的字段结构信息后,由用户选择需要过滤的字段,生成器能根据数据表的结构参数匹配bean中的相关过滤函数,最后生成具有数据过滤能力的客户端脚本代码文档。将生成器用于Web程序的开发,不仅能减少开发人员在编写、测试和修改代码工作量,而且能及时跟踪数据库(表)设计的改变,脚本代码生成高效、自动、准确。     

实践社区核心成员大五人格特征及其与沟通技能的关系

文章采用修订的大五人格问卷和自编的沟通技能问卷,对宁夏8家企事业单位中15家实践社区的核心成员进行了调查,结果表明:大五人格问卷和沟通技能问卷信度和效度良好;实践社区核心成员一般拥有敏感的、外向的、温和的、开拓性、高利他性、灵活性等人格特质;核心成员的沟通技能在年龄、职位、文化程度、单位性质等变量上均有不同程度的显著性差异;大五人格特质与沟通技能之间存在密切的关系,五个因素中的社交性、开放性和利他性对沟通技能水平具有较大的影响。     

The end of “information”: Computers,democracy, and the university

This paper describes some of the challenges which the growing pervasiveness of computers and electronic communications technology present to liberal democracies. We argue that these technologies, by their influence on the mechanisms of publicity and privacy, make possible the abuse of an under-developed popular epistemology. The confused response of the courts to cases of information crime suggests that the university is a better forum in which to meet and master these challenges.Freedom is not a simple experience. And as technology becomes more sophisticated, living in freedom—which means living with constant, changing choice—will only become more complex.
