关于真理的若干思考

真理作为具有现实性的理论，标志着思想图象与现实图象的符合与一致。根据来源的不同，真理分为反映性真理与创造性真理。反映性真理意味着主观符合现实，创造性真理则意味着现实符合主观。真理标准包括理论要件和现实要件。检验真理的直接途径包括感觉——理性分析和实践——感觉——理性分析两种类型。逻辑证明是检验真理的间接途径。     

Voices of teacher candidates of color on white race evasion: ‘I worried about my safety!’

Abstract

This qualitative study investigated the negative impacts minority teacher candidates receive from white teacher candidates in a required multicultural education class. The findings reveal that four teacher candidates of color had difficulty positioning themselves among the overwhelming silencing power of whiteness in the class. The white students were tactful at evading power and race and flattening the existing hierarchical power relations through the discourses of colorblindness and by preying on the minority instructor. Their understanding of diversity was also shallow. On the other hand, the teacher candidates of color were afraid that they might be labeled as the ones who spoke up against the white students and fearful of the possibility of retaliation and ostracism from the white peers. It seems that the teacher education program’s structure allowed the white candidates to impose strong negative peer pressure on the teacher candidates of color.

正确认识“三个代表”的重要思想

“三个代表”重要思想是江泽民总书记2000年2月在广东考察时提出的，在“七一”讲话中，江泽民总书记进一步论述了“三个代表”重要思想的科学内涵和精神实质，这一重要思想是对马克思主义的新发展，是新世纪党的建设的伟大纲领，要理解“三个代表”重要思想，首先要了解江泽民总书记提出“三个代表”重要思想的出发点和着眼点。“三个代表”重要思想从理论上看，第一，强调了“先进性”的主导原则，第二，突出了“慎终如始”的发展过程论；第三，注重了“三个代表”的整体性。     

Triadic interaction in clinical task-based interviews with mathematics teachers

A clinical task-based interview can be seen as a situation where the interviewer–interviewee interaction on a task is regulated by a system of explicit and implicit norms, values, and rules. This paper describes how documenting and mapping triadic interaction among the interviewer, the interviewee, and the knowledge negotiated can be used to increase procedural replicability of the interview and accuracy of drawn conclusions about the interviewee’s thinking process. Excerpts from interviews with 25 inservice mathematics teachers working on a task to make up a problem whose solution requires division of two fractions are discussed. The excerpts illustrate the relationship between methodological decisions taken by the interviewer during the interview and the applicability of the interview output to the research questions. A divergent analysis of the interviews with these teachers, which spanned over two years and were conducted by four interviewers, is used to offer a framework for analyzing data collected in clinical task-based interviews.

参透色空真境界,抛置乾坤再出家——郁达夫与禅宗文化关系论之二

郁达夫既逃禅又向往“爱情”,这曾令很多人感到困惑,但是仔细考察却不难发现,他在爱情中真正关注的并不是爱情本身,而是通过爱折射出的慰藉感和归宿感。爱的欢欣和美丽使他感动,但爱的易逝与多变也使他备感人生的空淡和无聊。当他在“爱、中参透“情禅”时,他的小说也一改早期的声泪俱下,痛器狂啸,变得澄净空明,平淡悠长,极富禅意。在中国现代小说史上,这是极其特殊的。

论英国在太平洋战争中的双重使命

太平洋战争初期，英国在东南亚的殖民统治被摧毁，英国对日宣战，英国从消极抗战到有限参战，到战争结束时积极抢占东南亚殖民地，表现出英国参战的双重性。英国最初想借美国之力夺回自己在东南亚的殖民地，后又担心被美国取而代之，因此英国一直在对日战争中走钢丝，经中美英三方不断协调。才最终确立了英国在东南亚战场的责任，但英国始终把重返东南亚作为其参战的条件，使它的对日作战打上殖民主义烙印。
