The transition to secondary school geometry: can there be a “chain of school mathematics”?

Students mainly perceive the transition to secondary school as an opportunity to start their school career anew. Reality often proves them wrong, especially in the case of mathematics. In our paper, we briefly discuss children’s transition to secondary school as both an opportunity and a problem, with reference to the Greek context. In discussions about the transition to secondary school and its effect on the teaching and learning of mathematics, primary and secondary school teachers in Greece often depict school mathematics as a “chain” of concepts and procedures. With this metaphor as our reference point, we discuss how ideologies about the teaching of mathematics are enacted in both school levels. We will base our discussion on the analysis of extracts taken from dialogues in primary and secondary school mathematics classrooms in Greece. In our analysis, we employ a Peircean view of semiotics in an attempt to conceptualize students’ rushed introduction to rigor in justifying mathematical statements in secondary school. These extracts are part of a longitudinal study that aimed, on the one hand, to pinpoint discontinuities and continuities in the teaching of geometry between primary and secondary schools and, on the other, to investigate whether a set of curriculum material that we designed could serve as a link in the teaching of geometry between the two school levels.     

Pre-kindergarten teachers’ use of transition practices and children's adjustment to kindergarten

This study describes pre-kindergarten teachers’ use of kindergarten transition practices and examined the extent to which these practices were associated with kindergarten teachers’ judgments of children's social, self-regulatory, and academic skills upon their entry into kindergarten. Participants were 722 children from 214 pre-kindergarten classrooms participating in the National Center for Early Development and Learning's (NCEDL) Multi-State Pre-kindergarten Study. Of nine transition practices intended to promote children's adaptation to kindergarten, pre-kindergarten teachers reported implementing, on average, six transition practices, with notable variation across pre-kindergarten classrooms. Children were judged by their kindergarten teachers to have more positive social competencies and fewer problem behaviors when they attended pre-kindergarten classrooms in which more transition activities were implemented and, specifically, in which teachers discussed curricula or specific children with kindergarten teachers. In addition, positive associations between kindergarten teachers’ perceptions of children's social competence and pre-kindergarten transition activities (total number of activities and activities that children experience directly) were stronger for children who experienced social and economic risks. Implications of these findings related to alignment across the pre-kindergarten to kindergarten settings to improve children's school readiness are discussed.     

浅谈对外贸易中的技术性贸易壁垒及其有效应对

我国加入WTO之后,随着对外贸易的不断扩大,传统的关税、配额等壁垒正逐步拆除,但遭遇的技术性贸易壁垒却越来越多,也越来越严重,尤其是发达国家,利用其话语权和游戏规则制定权的优势．使这类技术性贸易壁垒显得“合理”而隐蔽。对此,需要由政府制订应对方案、企业提高竞争能力,共同采取积极、有效的措施,以打破这类技术性壁垒的限制。     

走出学科危机:教育现代化进程中的大学学科建设

当代科学技术发展高度综合与交叉的新趋势对知识生产模式提出了新要求,大学传统上建立在知识分类体系基础上的学科制度在新知识生产模式下面临深刻危机,囿于学科壁垒的封闭式知识生产限制了大学的创新活力,知识生产过程中未能实现“学科逻辑”与“问题逻辑”相统一,学科存在的合法性与学科建设的有效性都受到质疑。通过历史与现实两个维度的审视,知识生产过程中对于专业化分工的需要没有发生根本性变化,对学者个体而言“专”是“跨”的前提,因此学科本身不会从大学里消亡。但未来的学科建设应当通过系统性变革,打破既有的学科壁垒,建立贯通知识生产中“营地”与“阵地”的矩阵式运行结构,促进学科的交叉、会聚与融合,使得学科在大学的科学研究、人才培养与社会服务等活动中更好地发挥作用。

论毛泽东的宪政思想及其嬗变

毛泽东的宪政思想缘起于新民主主义革命时期，在社会主义革命和社会主义建设的初期得到发展。民主集中制、党政分开、人民主权等原则是毛泽东宪政思想的主要特征。但是，因国内外条件的变化和毛泽东“左”倾思想的发展，毛泽东的宪政思想在其晚年发生了嬗变。     

科学选才:转型期中国高考政策变革的重要利益诉求

科学选才是中国高考政策的重要利益诉求,它较多与集中地反映了效率优先的理念,但与公平选才这一高考政策的基本利益取向存在一定的矛盾,在现有考试技术尚无法对考生进行准确、全面考评的情况下,科学选才成为转型期中国高考政策变革面临的现实难题。对此,可以通过改革高校招生计划管理形式、高考内容与形式、健全高考监督制约机制等措施,营造有利于科学选才的政策环境,提高高考改革的效度和信度。     

试析归化和异化翻译策略的选择

归化与异化是翻译中处理文化因素的两种不同的翻译策略——前者主要以目的语文化为归宿,后者主要以源语文化为归宿。归化与异化问题是中国翻译界激烈争论已久的问题。但是在具体翻译实践中,有利于目的语读者理解文化差异是决定翻译策略选择的主要因素,因此,应兼用两种翻译策略,实现让读者理解文化差异的目的。
