“概念的双重作用”与逻辑理论的证成——对冯契理论的一点引申与应用

冯契认为,一切概念都有摹写现实与规范现实的双重作用,逻辑原则也体现着后验性与先验性的统一.在逻辑理论的证成问题上,"概念的双重作用"要求逻辑理论的建构必须坚持后验性与先验性的统一.有见于现代逻辑论证理论的普遍主义、先验主义倾向,非形式逻辑试图从后验性与先验性、普遍性与情境性的统一中去证成自身.     

试述后现代精神观照下师生关系的重新审视

后现代主要并非指的是一种时态,而是一种思想态度和意识,以及一种崭新的思考问题的方法。师生关系是一种特殊的社会关系,是教育的全部蕴念所在。根据后现代基本精神,本文力图重新审视教育过程中目前已被广泛认可的师生关系,从一种全面的、多元化、多层次的视角反思传统的师生关系,从而对师生关系问题形成新的有益的认识,即师生关系应从二元对立的主客关系转变为相互作用的共生关系,由单向的知识传授关系转变为双向的平等对话关系,从理性保障的师生关系转变为情感保障的师生关系。     

“推类”的构成、本质与作用——三论“引譬、援类”

推类是中国古代推理的主要模式。其结构通常由"言事"与"言道"两个部分组成。"言事"与"言道"的核心是"喻"。其理论根据是:所言事与道之间共同存在的"义"。找到事与道之间共同的"义",便可"扶义而动,推理而行"。由"事"理过渡到"道"理。推类的本质是论证。如果我们较好地掌握了"言事"与"言道"这二者的关系及"引譬"、"援类"的思维方式,对于正确理解中国古代思想家们的思想和丰富我们的思维方式具有重要意义。     

BEING A LEARNER: A VIRTUE FOR THE 21ST CENTURY

ABSTRACT:  Lifelong learning is something which one does for oneself that no one else can do for one: it is a public and personal human activity, rather than private or individualistic. One of the features of the education system is the paucity of a language for learning as process and participative experience. Personalised learning requires a sense of the worthwhileness of 'being a learner'– a virtue in the 21st century. A sense of one's own worth as a person is essential to understanding one's identity as a learner. Research suggests the human capacity to learn can be understood as a form of consciousness which is characterised by particular values, attitudes and dispositions, with a lateral and a temporal connectivity. This 'consciousness' has several dimensions which are all related to becoming a person, with a learning identity. They also enable the learner to become aware of and appropriate what is of worth and map onto the sorts of core values that learning communities espouse. Awareness of self and of one's own worth as a person is a necessary condition for 'becoming a learner' and for identifying and engaging with 'what is of worth'. Furthermore, a sense of self as a learner is formed in relationship, and understood as one learns to tell one's own story, as a participant in the conversation of the learning community. Character is the way in which we refer to that quality of personhood in which there is rooted the capacity to change and learn over time.     

陈毅元帅战争诗词简论

陈毅元帅的战争诗词是20世纪生动形象的革命战争史，又是壮美深沉的民族精英心灵史：在审美上既重风骨，又富意境；在形式上古近体并重，且创作颇丰。陈毅其人品性高洁，风骨凛然，其诗亦然，是20世纪传统诗词当之无愧的大家。

Puzzle Pedagogy: A Use of Riddles in Mathematics Education

Abstract

In this article, I present a collection of puzzles appropriate for use in a variety of undergraduate courses, along with suggestions for relevant discussion. Logic puzzles and riddles have long been sources of amusement for mathematicians and the general public alike. I describe the use of puzzles in a classroom setting, and argue for their use as a basis for discussion of the nature of mathematics, for development of problem-solving skills and confidence, and as a means of engaging students from a broad range of mathematical backgrounds. I suggest a consistent use of puzzles in a low-pressure setting as a possible means of fostering inquiry and a positive learning mindset among students.     

“扶义而动，推理而行”——引譬、援类再探讨

推类是中国古代推理的主要模式。其结构通常由言事与言道两个部分组成。言事与言道的核心是“喻”。其理论根据是：所言事与道之间共同存在的“义”。找到事与道之间共同的“义”,便可“扶义而动,推理而行”。由“事”理过渡到“道”理。     

谈标志设计的审美意念

标志是一种特殊形式的创造．是符号化了的人类情感形式．是名副其实的形象代表。标志设计．无论从图案到文字．标志图形和标志文字．都得遵循从形象到意象的创作过程来传神达意。只有体现“名副其实，图文并茂．形神兼备”这三重设计境界．方能达到标志设计的至高审美意境。     

读诗论札记

诗歌是语言的艺术,更是文字的艺术。本文从"诗"字构成之义谈及:诗者,言也;诗者,寺也;诗者,持也;诗者,思也;诗者,私也。以及与"诗"音的"狮、师、蓍、施、尸"等字相关意义,以便更深刻地理解"诗"的原本之意。     

Human causality judgments and response rates on DRL and DRH schedules of reinforcement

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio (VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments, and that few current theories of causal judgment explicitly predict this pattern of results.

观众:作为电影叙事体中的不同角色

电影作为一种具有诱导性与强制性的叙事本,实质上左右了观众对影片意义的理解方式,同时为影片的全部意义提供一个潜在的认知结构。在这个结构中,对观众接受、体验方式的角色定位是电影制作极为重要的环节。电影观众便成为一个由电影的制作、观看与观看情境共同建构的电影叙事体系中的角色,一个我们可以潜入其中“窥视”影片内容的“假想替身”。不论是作为“窥视”、“先知”还是“认同”,观众都已经成为电影叙事本中的一部分,观众都被建构为叙事的主体并与影片的作共同“生产”影片的意义。     

教育研究之生命意识探寻

教育研究之生命意识,是对教育研究存在自身的思寻,是对教育研究自身作为一项有生命活动的思寻。教育研究之生命意识为教育研究者自身生命之意识,是教育研究者之个性的自我意识;教育研究之生命意识在于以整个生命的方式进行教育研究,要求以对生命的敏感性和理性关切来进行教育研究,让感官和人心都活跃起来;教育研究之生命意识表现为对生命和教育研究的一种精神担当,是对生命和教育的不断追问和困惑,而非给生命和教育提供技术方案,在于对教育和生命之赤子情怀和真性情;教育研究之生命意识蕴含于对生命和教育的宽恕,在于对教育研究的一种多元追求和关注。

Emergence of a learning community: a transforming experience at the boundaries

I narrate a process of transformation, a professional and personal journey framed by an experience that captured my attention shaping my interpretation and reflections. From a critical complexity framework I discuss the emergence of a learning community from the cooperation among individuals of diverse social and cultural worlds sharing the need to change a traditional professional development program structure and develop a new science education Masters Degree/Certification program. I zoom into the continual redefinition of the community, its evolution and complex interrelations among its participants and the emergence of a learning community as a boundary space having an emancipatory role and allowing growth and learning. I analyze the dialectical relationship between agents’ behavior either impeding growth or having an emancipatory function of a mindful RelationalAct in a complex adaptive system framework.

服装造型当中辅料的运用

服装设计并非洋洋洒洒的效果图或稀奇古怪的款式造型，而是服装造型与服装材料之间美的和谐、美的升华。任何优秀的服装都是设计与材料的完美结合。从某种意义上说，服装设计就是服装的造型风格的设计。服装造型的体现要有相应的辅料来支持。不同的辅料具有不同的表现性，辅料特征对服装的造型起到了至关重要的作用。可以说，服装的造型风格在很大程度上是由辅料的风格决定的。
