对流占优扩散方程的几个特征差分格式

文章研究了一类线性对流占优扩散方程的初边值问题.采用了A.A.Samarskii构造差分格式的思想,对方程的扩散项进行修正,构造了线性对流占优扩散方程的显、隐式特征差分格式和C-N格式,三个格式的收敛阶均为O( h2),利用Fourier方法分析论证了其稳定性和收敛性.     

远程教育“无显著差异现象”研究评述

本对当前关国远程教育界最有争议的“无显差异现象”研究进行了介绍、分析和评价。此研究的作罗塞尔在概括了以前355项远程教育比较研究的基础上,指出参加远程学习与面授学习的学生学习成绩不存在显差异。我们通过分析发现这类研究在设计思想和研究方法上有一定局限性,并建议今后的远程教育教学和研究应该建立起以学生为中心的理念,采用多元评价方法,并正确认识技术媒体在教学中的作用。

现象学对于教育研究的意义

将作为当代最重要的哲学方法论之一的现象学，置于教育研究的语境内，回答这样一系列问题：在现象学的意义上，当“教育”被称为是“现象”的时候，意味着什么?现象与教育怎样建立了实质性的联系?从教育学出发理解的现象学是什么?什么是教育现象学?采用现象学的方法对于教育研究者而言，意味着什么?最终将现象学对于教育研究的启发定位在“学会看”，并主张以现象学的态度和精神来进行教育研究。

Addressing Social Difference with Prospective Teachers Who Want “To Make a Difference”

This paper focuses on a cohort of B.Ed. students' understandings about social difference and social justice as recorded in their professional journals in the first semester of third year. It shows that their reasons for choosing teaching as a career, reflections on their school experiences and discussions about future students are grounded in the culture of individualism that is commonplace in Australian society. However, some also acknowledge that class, race, gender and ethnicity shape their lives and their future students' worlds. Furthermore, most were prepared to engage with social justice in their professional journals. Keeping these findings in mind, the paper identifies discursive spaces where teacher educators might work with prospective teachers to promote critical reflection about social difference and facilitate a commitment to social justice in education.

Choosing the Right Subjects in Significant Life Experiences Research

Research on significant life experiences (SLE) can achieve its potential importance only when it studies the right people for the right reason. Here I scrutinize ten research reports, and conclude that many do not. Historical information is incorporated in text and footnotes to place SLE research into the intellectual history of contemporary environmental education.

Effectiveness,Difference and Sociological Research

This article addresses Making the Difference (Connell et al., 1982) as a research project, in the specific context of Australian education and Australian sociology. It argues that the form of its research and writing have been as influential as the argument itself, and illustrates these themes by comparing that project of the early 1980s with two more recent Australian projects of the late 1990s. It is suggested that Making the Difference was successful in illustrating class and culturally based inequalities in the form of Australian schooling, and in illuminating some gendered processes of that schooling, but that its proposal for an 'organic working class curriculum' was difficult and utopian in conception, and quickly overtaken by broader interests in school 'effectiveness', and political moves to 'third way' policies rather than class war. It is argued that the Queensland New Basics project illustrates some of the lessons of engagement and communication offered by Making the Difference , and also the pragmatism of this new political context; and that the longitudinal 12 to 18 Project attempted to build on insights about class and gender of the earlier work, but with attention to some of the limitations of the type of focus on class of that work.     

What is a Significant Educational Experience?

This article analyses the nature of an educational experience by taking as its starting point Dewey's Art as Experience in order to identify what it is that counts as a significant or worthwhile experience. Dewey suggests that an experience needs to have an integral character in which the different phases of the experience are related and which tends towards a conclusion. Furthermore, an experience also needs to have the character of what Dewey calls an ‘undergoing’, an engagement with content which may be difficult or painful. It is suggested that this kind of experience may be seen in terms of a ‘light’ pedagogy in which content is allowed to unfold. This is contrasted with educational experiences that are ‘teacher‐driven’ or ‘learner‐driven’.
