Question‐posing and question‐responding: the heart of ‘Possibility Thinking’ in the early years

Drawing on research that sought to explore the characteristics of ‘Possibility Thinking’ as central to creativity in young children's learning, this paper considers question‐posing and question‐responding as the driving features of ‘Possibility Thinking’ (PT). This qualitative study employed micro‐event analysis of peer and pupil–teacher interaction. Events were sampled from two early years settings in England, one a Reception classroom (4‐ to 5‐year olds) and the other a Year 2 classroom (6‐ to 7‐year olds). This article arises out of the second stage of an ongoing research programme (2004–2007) involving the children and practitioners in these settings. This phase considers the dimensions of question‐posing and the categories of question‐responding and their interrelationship within PT. Three dimensions of questioning were identified as characteristic of PT. These included: (i) question framing, reflecting the purpose inherent within questions for adults and children (including leading, service and follow‐through questions); (ii) question degree: manifestation of the degree of possibility inherent in children's questions (including possibility narrow, possibility moderate, possibility broad); (iii) question modality, manifestation of the modality inherent in children's questions (including verbal and non‐verbal forms). The fine‐grained data analysis offers insight into how children engage in PT to meet specific needs in responding to creative tasks and activities and reveals the crucial role that question‐posing and question‐responding play in creative learning. It also provides more detail about the nature of young children's thinking, made visible through question‐posing and responding in engaging playful contexts.     

场独立和场依赖认知风格对大学生听力理解能力的影响

Witkin认知风格理论中通过镶嵌图形测试将学习者认知风格分为场独立性和场依赖性两种,场独立风格的学习者对外界或背景依赖程度小,场依赖风格的学习者对外界或背景的依赖程度大。场独立和场依赖认知风格对学习者的二语习得能力具有不同影响,听力理解能力同样受到不同认知风格的影响,学习者认清自身认知风格并在教师指导下有针对性地进行策略训练将有效提高听力理解水平。     

基于社会资本理论的社交问答用户健康信息行为研究

[目的/意义]社交问答用户的社会资本受多种因素影响，本文旨在探究社交问答用户不同的健康信息行为对其社会资本积累的影响。[方法/过程]以知乎网上糖尿病话题下2 537个问题帖子，3 567个回答的1 650名用户为研究对象，依据L.Nan的社会资本理论和N.Uphoff对社会资本的分类，将社交问答用户的社会资本分为认知性和结构性两类，用多元线性回归的方法分析社会问答用户的健康信息行为与社会资本之间的关系。[结果/结论]用户的健康知识贡献行为和自我信息披露行为在不同程度上正向促进社会资本的累积，而不同的健康知识获取行为对认知性社会资本和结构性社会资本的影响有差异。这些结果有助于社交问答用户提高社会资本，平台完善用户服务和激励机制。     

The world without Bandung,or for a polycentric system with no hegemony

The first wave of revival of States and nations of Asia and Africa which shaped major changes in the history of humankind organized itself in the Bandung spirit in the frame of countries Non-Aligned on colonialism and neo colonialism, the pattern of globalization at that time. Now, the same nations, as well as those of Latin America and the Caribbean, are challenged by neo-liberal globalization, which is no less imbalanced by nature. Therefore, they must unite to face the challenge successfully as they did in the past. In some countries “sovereign” projects are developed that associate active State policies aimed at systematically constructing a national integrated consistent modern industrial productive system, supported by an aggressive export capacity. Views with respect to the degree, format and eventual regulation of opening to foreign capital and financial flows of all kinds (foreign direct investments, portfolio investments, speculative financial investments) differ from country to country. Policies pursued with respect to the access to land and other natural resources also offer a wide spectrum of different choices and priorities.

认知视域下社会化问答社区用户知识采纳行为的影响因素——基于扎根理论的探索性分析

【目的/意义】社会化问答社区目前已成为网络环境下用户搜寻和获取知识的重要途径。探析用户知识采纳行为有助于提升社会化问答社区知识组织与服务能力,对社区的运营管理方面也具有重要的实践意义。【方法/过程】本文选取知乎作为研究对象,应用扎根理论方法,通过数据资料收集、三级编码等过程,结合认知心理学的相关理论,构建了社会化问答社区用户知识采纳行为模型。【结果/结论】研究发现:自我认知、平台认知、社会认知三个维度对用户知识采纳行为具有显著影响,并通过认知有用性、认知易用性两个中介变量和技术、情感因素两个调节变量分别刺激用户知识采纳的意愿,从而影响知识采纳行为。【创新/局限】从认知视域基于扎根理论的方法探索社会化问答社区知识采纳行为的影响因素模型,但采集的知乎的样本容量较小,概念模型的信度和效度并未经过大样本检验。
