时间知觉阈限的双脑不对称性

时间知觉阈限并非单个概念，而是依赖于不同判断标准在不同时间经验问的分层级的门槛，并可能对应着不同时距范围内时间信息加工的不同机制。研究用分视野呈现技术考察了大脑两半球在三种不同反应标准下测定的短时距刺激时间知觉阈限上的差异，结果表明：（1）三种反应标准和不同呈现方位条件下，极限法测定的时间知觉阈限存在显著差异，二因素的交互作用不显著；（2）就时间知觉阈限而言，左半球存在着时间信息加工上的相对优势；（3）“同时-非同时”的阈限最低，其次是“连续-分离”的阈限，最后是“先后顺序”的阈限。     

对中小学实施英才教育的思考

纵观当今世界，英才在国家的发展中起着举足轻重的作用，而英才的涌现需凭借英才教育的大力发展，因此，必须从时代的发展，人的发展，以及教育自身发展的高度充分认识实施英才教育的重要性，使英才教育成为我国教育发展不可或缺的重要的战略目标，当前，在我国发展英才教育还存在诸多困难，既要充分解放思想，更新教育观念，又要做好教育制度的创新工作，为英才教育的发展创造条件，为英才的脱颖而出开辟新的天地。     

规约与重释:比较教育研究中几个基本问题的检视

理性地审视比较教育的研究现状,存在着比较教育概念泛化、学科界限不明、研究者语言与文化语境匮乏以及研究立场偏狭等问题。这些问题应引起学界的关注与思考。

Philosophy of being and becoming: A transformative learning approach using threshold concepts

Transformation has been the fundamental basis upon which education has always stood, as without transformation in mind, education would seem purposeless and undirected. This would imply that the objective of providing information in education is not just to gain knowledge but to achieve the desired transformation in character or behaviour by applying the knowledge learnt within ourselves. Based on how information is interpreted and managed, the philosophy of information influences our states of being and becoming which have an impact on our understanding of the information world. This paper discusses the philosophical aspects of being and becoming in relation to transformation, and threshold concepts are explored as a means of achieving transformative learning.     

The truth,but not yet: avoiding naïve skepticism via explicit communication of metadisciplinary aims

ABSTRACT

Introductory students regularly endorse naïve skepticism – unsupported or uncritical doubt about the existence and universality of truth – for a variety of reasons. Though some of the reasons for students’ skepticism can be traced back to the student – for example, a desire to avoid engaging with controversial material or a desire to avoid offense – naïve skepticism is also the result of how introductory courses are taught, deemphasizing truth to promote students’ abilities to develop basic disciplinary skills. While this strategy has a number of pedagogical benefits, it prevents students in early stages of intellectual development from understanding truth as a threshold concept. I argue that we can make progress against naïve skepticism by clearly discussing how metadisciplinary aims differ at the disciplinary and course levels in a way that is meaningful, reinforced, and accessible.     

中小学生不良数学信念的表现及成因

中小学学生的不良数学信念，主要表现在如何对待数学、如何对待数学学习两个方面。学生所以产生不良数学信念，既与教师、教材、教法及教师的数学现有关，也与学生的自我意识有关。分析学生不良数学信念的表现及产生原因，有助于教师帮助学生树立正确数学信念以提高数学教学质量。     

Located in the thin of it: Young children’s use of thin moral concepts

One important socio-cultural medium through which young children’s moral understanding is cultivated is parent/child discourse. Of particular interest to us was young children’s use of basic (‘thin’) evaluative concepts (good, bad, right and wrong), which are ubiquitous in everyday discourse and serve as a potential bridge from the non-moral to the moral domain. We investigated 14 2–5-year-old children’s (and their parents’) use of thin evaluative concepts and found that while they frequently used good and bad to morally evaluate other people’s and their own psychological/dispositional states and behaviors—as well as, less frequently, to highlight relevant standards, expectations and rules—they did not use right and wrong. In contrast, a sample of US written and spoken public conversation revealed that adults did. Reasons for this are discussed, along with the frequency of different types of moral evaluations, differences between children and their parents, and age-related trends.
