"天人合一"理解分歧的症结在于缺乏对"天"的无限性的诠释。数学语境的独到之处在于能描述这个不可观测的、大而无外、小而无内的"天"的无限性。借用线性几何系统构建了数学语境下"天人合一"的&... "天人合一"理解分歧的症结在于缺乏对"天"的无限性的诠释。数学语境的独到之处在于能描述这个不可观测的、大而无外、小而无内的"天"的无限性。借用线性几何系统构建了数学语境下"天人合一"的"天",是N维(N→∞)的多维宇宙空间,指出"天"是一切的投影源,N-1维及以下是其投影的相。"天人合一"的"人"是"大我","合一"代表一种境界或一种趋势:对于圣人来说,"天"和"人"本来是一体的,不必再去"合";对于一般人来说是指人效法天地,"合一"表示一种趋势,在数学语境下可表达为lim_(n→∞)^(n/n)=1。 展开更多

在语境论的视角下,研究数学就是研究数学语境。文章通过对数学语境的结构分析,阐释了数学语境的基本特征:1.数学语境是语形、语义、语用相互作用的统一有机体;2.数学语境是具有边界的;3.数学语境处于不断再语境化的过程中。这些特征表明... 在语境论的视角下,研究数学就是研究数学语境。文章通过对数学语境的结构分析,阐释了数学语境的基本特征:1.数学语境是语形、语义、语用相互作用的统一有机体;2.数学语境是具有边界的;3.数学语境处于不断再语境化的过程中。这些特征表明,为数学的本质提供一种语境论进路具有重要的理论和现实意义。 展开更多

There have been great improvements in English teaching in China since the adoption of the New National English Curriculum, however, there are still some problems in western Sichuan province in China. Silent class is found through the author's observation of some English lessons in some senior schools. This paper analyzes the situation of classroom interaction in English teaching in southwestern China and explores the reasons of silent class based on the analysis of the statistics drawn from questionnaires. The reasons are illustrated from three perspectives: teacher-centered class, exercises-based teaching, and learners' instrument learning motivation. The author suggests some proposals to solve the problems, such as changes of teachers' roles, creation of stress-free learning environment, and use of task-based teaching, which aims to make teachers consider using interactive language teaching to cultivate learners' whole abilities and to improve the efficiency of teaching and learning. 展开更多

Serve to introduce decision context and decision implication to Formal Concept Analysis (FCA). Since extracting decision implications directly from decision context takes time, we present an inference rule to reduce the number of decision implications. Moreover, based on the inference rule we introduce the notion of a-maximal decision implication and prove that the set of all α-maximal decision implications is α-complete and α-non-redundant. Finally, we propose a method to generate the set. 展开更多
