Re-mythologizing mathematics through attention to classroom positioning

With our conceptualization of Harré and van Langenhove’s (1999) positioning theory, we draw attention to immanent experience and read transcendent discursive practices through the moment of interaction. We use a series of spatial images as metaphors to analyze the way positioning is conceptualized in current mathematics education literature and the way it may be alternatively conceptualized. This leads us to claim that changing the way mathematics is talked about and changing the stories (or myths) told about mathematics is necessary for efforts to change the way mathematics is done and the way it is taught.

“What are you Representing?” Contesting Identities of Incarcerated Youth

This article explores how incarcerated youth and adult supervisors contest claims to identity via language of “representing”. Comparing how youth and adults “represent” in discussions of their own past and future selves sheds light on the constrained universe of discourse within which both groups work to express identities and on the basis of which we counsel, mentor, and educate young people. Acknowledging these constraints can contribute to understanding what I call exceptionalism—the idea that only exceptional poor and raced young men, through great personal effort and sacrifice, may resist the lure of the “street”. I conclude by discussing implications of this work for education and youth development work both inside and beyond the juvenile justice system as well as for research across lines of difference by committed “outsiders”.

基于MD5分组变序的远程教育系统动态身份认证

大学生身份焦虑研究——一项网络实证调查

通过某大学生QQ群对大学生身份焦虑问题进行了讨论和访谈,并将讨论和访谈内容进行归纳和整理,编制了问卷,对包括00群在内的182名大学生进行了调查,回收有效问卷178份,有效回收率为97．8名。通过数据分析,将大学生身份焦虑的成因归纳为四大类：一、“好孩子”身份的焦虑;二、未来成功期盼者的“焦虑”;三、爱与被爱者的焦虑;四、社会资本积累者的焦虑。     

质的研究中研究者个人身份问题探析

研究者个人身份的反省在质的研究中具有重要意义。研究者个人身份的探讨,其本质就是对于研究者体性特征、研究者个人冲突、研究者与研究对象保持的研究关系的现实审视,这也是反思研究者个人身份的三个基本维度。研究者个人身份构建的现实策略是：研究者体性印象的管理;研究者＂前见＂中介作用的发挥;研究者＂附加身份＂的退场;研究者情感的在场。     

西方关于青少年族群认同研究的现状和进展

族群认同是少数民族青少年心理发展的重要内容,它和青少年的自尊、社会适应、心理调适、社会行为均有显著的相关。国外在社会认同理论和发展理论的指导框架下,对青少年的族群认同进行了大量的研究。本文对国外青少年族群认同的研究进行了综述,内容涉及西方青少年族群认同研究的理论背景、族群认同的定义和操作化、族群认同的测量等,以期对我国青少年族群认同的研究提供借鉴。

Abstract：

Ethnic identity is an important part of adolescents development for minority ethnic groups,it is significant related to the self-esteem,social-adjustment,social behaviors and so on.Under the guidance of the Social Identity Theory and the Development Theory,there have been a lot of research on this topic among adolescents in western countries.This article gives a overall review on this area,the content contains the background of the theory perspectives,the conceptualization and measurement of the ethnic identity,and suggestions for future study are discussed.     

Towards a collaborative,interactionist model of teacher change

The aim of this article is to extend the scope of the models of teacher change to an interactionist view which co-ordinates sociocultural and constructivist perspectives. Accordingly our focus will be on the cultural and situational factors and processes of social interaction, as well as on the development on an individual level. First we study how roles, statuses, expectations as well as social and socio-mathematical norms were formed in the group of four student teachers, when they were co-planning, teaching and assessing mathematics lessons during their teaching practice. Finally, we attempt to construct a collaborative, interactionist model of teacher change integrating sociocultural and constructivist perspectives.     

Seeing one another as “other”

In this paper, the authors discuss two complementary life history research projects investigating prospective teachers' identities in relation to their race and social class. Drawing on the experiences of one student from each study, they show how both whites and students of color primarily thought about one another as “others”—people who fundamentally differed from one another and whom they understood through preconceived ideas about a group. The authors draw on a Bakhtinian notion of how a “surplus of sight” enables one to develop understandings of an “other” and also of oneself.     

The scholarship of research in teacher education in a higher education institution in transition: Issues of identity

This paper examines perceptions of professional and organizational identity of teacher educators in a ‘new’ University of Technology in South Africa, resulting from several recent mergers of colleges of education and colleges of technology mainly serving formerly disadvantaged students and schools. The findings show that most staff consider teaching and research as dichotomous. Research activities are seen to satisfy the institutional requirements for securing research funding and producing publications. Professional identities could be strengthened by a faculty-wide debate on the specific profile of teacher education in a University of Technology, resulting also in an agreed research ethos. Peer support in collaborative research groups with a focus on own practice is seen as an opportunity to strengthen research expertise.     

Identity formation of teacher–mentors: An analysis of contrasting experiences using a Wengerian matrix framework

In order to understand the process of identity formation in a community of practice, Wenger (2002) proposes a matrix framework whereby three qualities (connectedness, expansiveness and effectiveness) are matched against three modes of belonging (engagement, imagination and alignment). In this paper we use this framework to analyse the experiences of two teacher–mentors and interpret how their identities are formed during the process of mentoring student–teachers. Factors that contribute significantly to the development of their identity include the school culture, the ‘personalities’ of the other community members, and the influence of other relevant communities of practice.
