Teacher Reflection Narratives: A poststructural approach

This study focuses on critical incident analysis in initial teacher education and the part played by the professional learning conversation. A reflection framework was used to identify changes in levels of reflective practice. Conversational skills of the supervising teacher in recognising the ‘person’ in the student teacher, and their management of the student's emotions, appear central to unlocking and increasing critical reflective practice. Dialogues that focused only on training standards, using evidence from practice to ‘sign off’ particular standards, were concerned more with the routines of teaching and less with increased and considered analysis of practice and change.     

Interrogating students’ perceptions of their online learning experiences with Brookfield’s critical incident questionnaire

This article discusses whether the very act of accessing online students’ experiences of teaching may itself foster students’ sense of belonging to a learning community. The article reports and reflects on the application of Brookfield’s critical incident questionnaire (CIQ) in postgraduate courses delivered online in 2008–2010 through the University of Newcastle in Australia. The anonymous CIQ is designed in part to access students’ views of teaching practice, and was deployed as part of an ongoing interest in quality teaching. The article makes recommendations for deploying the CIQ in online learning spaces and concludes with some reflections on unexpected opportunities thoughtful CIQ deployment may provide. The practice of sharing students’ anonymous responses may have helped to foster students’ sense of a shared learning community. This may be particularly valuable in an asynchronous online learning context where students are typically geographically isolated from one another.     

鸿宾楼事件与回汉关系的调适

1948年河北定县鸿宾楼事件的发生有着复杂的历史种现实原因.在应对事件和调适回汉民族关系的过程中,中共地方干部以党的民族政策为指导,在尊重回族文化习俗、相信回族党员群众、克服大汉族主义、注重对回族群众政策宣传教育、建立民主高效的民族工作机制等方面的成功实践,对当时尚缺乏应对此类民族突发事件经验的其他解放区具有范例意义,对建国后党和政府应对此类事件和增进民族团结也具有明显的镜鉴作用.     

武则天“扼婴”事件考疑

武则天"扼婴"成为这位杰出女皇一生最残忍的罪恶,使她不仅不能成为伟大女性,而且连普通母亲都不配。在历史上,她成为一个最残忍的母亲,为了政治向上爬,甚至亲手扼杀自己的亲生幼女,连起码的人性都可以不要。从1300多年来的史籍中,这似乎已经成为铁定事实。其实,历史记载有许多不可解释的疑问和矛盾,实际上这只不过是封建文人对这位女皇的强加之罪,原因就在于她是我国历史上唯一的伟大的超凡女皇,这是封建社会男子中心社会所不允许的。通过对多种史料的考证,事件过程的对比,用确切的史实证明,考疑这实在是历史上一件天大冤案:女皇武则天不是一位残忍至极失去母性的人。

Looking Inward: The impact of race,ethnicity, gender,and social class background on teaching sociocultural theory in education

In this paper I examine how and to what extent various elements of my biography—race, ethnicity, gender, age, social class background, and prior personal and professional experiences—influenced my relationships with students in a graduate course examining the impact of race, gender, and social class on education. My lived experiences as an immigrant woman of color in United States society and my prior professional experiences as an urban teacher are shown to have strengthened my expertise and confidence in teaching this course. Nevertheless, experience confirmed my initial concerns that my race, gender, and social class background negatively influenced some students' perceptions of my teaching competence and position of authority in the classroom. The paper concludes with recommendations for teacher education, including encouraging teachers to continuously engage the question of how their biographies shape their pedagogies and relationships with students, an important undertaking as our schooling populations become more racially, ethnically, and linguistically diverse. I also recommend that universities continue to recruit faculty who are not only from racial minority backgrounds but also from varied ethnic and social class backgrounds.     

九一八事变前中国东北的社会情况

九一八事变前,在奉系军阀主政中国东北的情况下,由于采取了一系列的措施,东北的耕地面积不断扩大,粮食产量不断提高,工业生产蒸蒸日上,同时也促进了东北金融业及民族资本主义的发展,为东北地区城市的发展与近代化做出了贡献。在一定程度上打破了日本垄断中国东北政治、经济、文化的局面,同时也刺激了日本进一步侵略中国东北的野心。

2008年汶川大地震期间发生的＂范跑跑＂事件和＂普世价值＂争论启示我们：必须坚定不移地用社会主义核心价值体系引领纷繁复杂的社会思潮,必须重视社会主义核心价值体系引领社会思潮的原则、方法和策略问题。唯有如此,才能巩固社会主义的主流意识形态、打牢党和人民团结奋斗的共同思想政治基础,确立构建社会主义和谐社会的共同目标取向,夯实中国特色社会主义事业的根基。
