Explanations of attitudes to change: Colombian mathematics teachers’ conceptions of the crucial determinants of their teaching practices of beginning algebra

This article arises from a study whose overall purpose was to investigate the relationship between Colombian mathematics teachers’ conceptions of beginning algebra and their conceptions of their own teaching practices. The teachers’ understandings of their teaching practices were explored with a view to unravelling their conceptions of change in their teaching. Focusing on the perspectives of teachers afforded opportunities that exposed the powerful role that the teachers’ conceptions of social/institutional factors of teaching played in their conceptions of their practices. The degree to which the teachers attributed these (external) factors as crucial reasons for what they do in their teaching was the basis of a categorisation of their conceptions of the crucial determinants of their teaching practices into three types. The findings are particularly relevant to our understanding of the stability of mathematics teaching approaches in the Colombian context but have likely implications for a range of international education contexts. Specific implications for the development of the research into teachers’ conceptions of mathematics and its teaching, and for teacher education programmes are presented.

Mindset change in a cross-cultural context

Imagine you are Thai and a member of a management team from a European company that acts in an Asian emerging market. Imagine you are a European expat with the assignment to double the turnover from that Asian company in a few years. Imagine you are a Change Maker and they ask you to facilitate the (multinational) management team of that Asian company to develop a market strategy and translate it into a business plan, and you have to deal with cultural differences. How do you manage a small-scale change process based on the principles of action learning in that specific multinational context? That's the essence of this account of practice.     

从两唐书《杜甫传》看杜甫诗学地位的变化

杜甫是我国文学史上一位集大成的诗人,他的诗对后世影响巨大,被后人尊为“诗圣”。他的诗歌被接受有一个渐进的过程,而宋代则是一个关键时期。他的诗在唐末五代已颇有影响,到宋代则形成了一个学杜的高潮。通过《旧唐书.杜甫传》和《新唐书.杜甫传》的比较,可以看出杜甫诗歌接受从唐末五代到宋代的变化过程。     

Mathematical biography and key rhetoric

The intention of this article is to consider the use of narrative and rhetorical inquiry as research methods. I construct a mathematical biography of one elementary teacher trainee, Sirpa, who had performed well in her advanced mathematics course in upper secondary school. I describe her development as a mathematics teacher during teacher education from her second-year methods course and teaching practice to fourth-year teaching practice. Narrative inquiry is more than a case study: Sirpa’s mathematical biography is a story that describes how she constructs her mathematical identity. I also analysed the key rhetoric that Sirpa used in her talk, key rhetoric here referring to the strategy by which she constructed continuity and coherence.

三线建设与六盘水生态环境之变迂

上世纪60年代中期开始,三线建设在六盘水全面铺开。由于当时重开发建设,轻环境保护,环保意识不强。随着六盘水矿区规模的不断扩大,境内环境开始受到污染,生态遭到破坏。出现“三废”污染严重,地下水下沉、枯竭,森林资源缩减,水土流失严重,自然灾害增多等诸多现象。

中国化马克思主义的历史生成及概念变迁

马克思主义中国化与中国化马克思主义构成了中国化马克思主义历史生成的双重语境。中国化马克思主义的理论概念经历了由中国的马克思主义—当代中国马克思主义—中国特色社会主义的历史变迁过程。中国特色社会主义道路与中国特色社会主义理论体系的逻辑互动体现了中国化马克思主义理论形态与实践形态的当代统一。     

社会转型时期温州商会的作用和组织结构
