This article has no direct link with academics, children, students or those who teach: I severed almost all such connections several years ago. It describes the rewards and challenges of leading a reminiscence group of elderly people, all of whom suffer some level of memory loss and/or severe physical disability; most are wheelchair-bound. It contains examples of their autobiographical talk which I recorded separately from group meetings and transcribed, exclusively for the satisfaction of each individual concerned. Ours is not a society which cherishes its aged members. What becomes of their identity? Who are they now? They are, of course, people – as interesting as those in our classrooms. They too need to know their own worth. 相似文献

The experiment in which a candle is burned inside an inverted vessel partially immersed in water has a history of more than
2,200 years, but even nowadays it is common that students and teachers relate the change in volume of the enclosed air to
its oxygen content. Contrary to what many people think, Lavoisier concluded that any change in volume in this experiment is
negligible; moreover, the explanation relating oxygen consumption in the air with its change in volume is known to be wrong.
In this work we briefly review the history behind the candle experiment and its relationship with some typical erroneous explanations.
One of the key factors behind Lavoisier’s success was the use of experiments carefully designed to test different hypotheses.
Following these steps, we performed several closed volume experiments where the candle wick was replaced by a capillary stainless
steel cylinder supported and heated by a nichrome filament connected to an external power supply. Our recorded experiments
are displayed as web pages, designed with the purpose that the reader can easily visualize and analyze modern versions of
Lavoisier’s experiments. These experiments clearly show an initial phase of complete combustion, followed by a phase of incomplete
combustion with elemental carbon or soot rising to the top of the vessel, and a final phase where the hot artificial wick
only evaporates a white steam of wax that cannot ignite because no oxygen is left in the closed atmosphere. After either a
complete or incomplete combustion of the oxygen, our experiments show that the final gas volume is nearly equal to the initial
air volume. 相似文献

This study aimed to investigate and compare the impact of pursuing top university status on the management and academic practices of two departments in a top-ranked institution in Taiwan. Qualitative interviews, official policy documents, website resources and relevant documents were the main sources of empirical data. Interview data were collected from 10 interviewees, the department heads and four full-time academics in both departments. This study found that departments and academics were required to plan and work in accordance with the university’s overall development plan and the two departments played different roles in contributing to various aspects of the university managers’ idea of what a world-class university is. This should be understood within the unique and complex academic tribes of different subject fields and the deeply rooted dimensions of Chinese culture in Taiwan. 相似文献

The concept of metacognition refers to one’s knowledge and control of one’s own cognitive system. However, despite being widely
used, this concept is confusing because of several reasons. First, sometimes it is not at all clear what is cognitive and
what is metacognitive. Second, researchers often use the same term, namely, “metacognition” even when they refer to very different
aspects of this complex concept. Alternatively, researchers may use different terms to indicate the same metacognitive elements.
Another foggy matter is the interrelationships among the various components of metacognition discussed in the literature.
This conceptual confusion regarding the concept of metacognition and its sub-components calls for in-depth theoretical and
conceptual clarifications. The goal of this article is to portray a detailed example of a conceptual analysis of meta-strategic
knowledge (MSK) which is one specific component of metacognition. This specific example is used to draw a general model for
conceptual analyses of additional metacognitive components. The approach suggested here is to begin with a clear definition
of the target sub component of metacognition, followed by a systematic examination of this sub component according to several
dimensions that are relevant to metacognition in general and to that sub component in particular. The examination should include
an analysis of how the details of the definition of the target sub-component refer to: (a) general theoretical metacognitive
issues raised by prominent scholars; (b) definitions formulated and issues raised by other researchers who have investigated
the same (or a similar) sub-component and, (c) empirical findings pertaining to that sub-component. Finally, it should be
noted that since metacognition is a relational rather than a definite concept it is important to situate the context within
which the conceptual analysis takes place. 相似文献

启蒙运动建立起来的主体迎合了资本主义制度建立的需要,这是一个崇尚理性、科学和自由的主体,一个反对传统和权威的主体。但这样的主体后来遭到了尼采、弗洛伊德、海德格尔和后现代主义者等众多学者和流派的批判。时至20世纪下半叶以来,其存在的根基发生动摇。流行一时的主体哲学是否走到了尽头,是否临近“黄昏”,是当今学者正在进一步思考和探究的问题。 相似文献

Standard presentations of optics concentrate on ideal systems made for imaging which bring all rays from a point source to one focus. But, in Nature, or in realistic optical systems with defects, rays do not behave precisely in this way. Rather than the focus simply being blurred, the rays, after reflection or refraction, form beautiful and rather universal patterns of bright lines known as caustics. Mathematically speaking, a family of rays is best viewed as a surface in a higher-dimensional space where we keep track of both the position and direction of rays. The intensity enhancement on approaching the caustic line is a singularity, arising from projection of a smooth surface from higher dimensions to lower dimensions. The universal features of such singularities, which arise in many contexts beyond optics, formed a major theme of Vladimir Arnold’s work after 1965, when he was exposed to René Thom’s vision of ‘catastrophe theory’. Arnold and his school made seminal contributions to singularity theory. 相似文献

Disorientation and navigation inefficiency are the consequences of the fragmented and incoherent structure of most hypertexts. To avoid these negative effects, researchers recommend—among other things—an interface with a structural overview of the relations between sections. Some authors have found that with such an overview, information is looked up faster and remembered better. This study examined whether a structural overview also leads to a deeper understanding. Forty students read a hypertext about the effects of ultraviolet radiation in one of two presentation conditions (structural overview and list). In the list condition, the same topics were mentioned as in the overview condition, but just in the format of a list. After reading, they answered textbase questions which measured their recognition and also inference questions supposed to measure their situation model constructed from the information read. The last type of questions indicated the readers' understanding of the text. On textbase questions, subjects with low as well as high prior knowledge scored equally well in both conditions. In contrast to our expectation, the overview did not improve the recognition of main points. However, on situation model questions low prior knowledge subjects scored significantly lower in the overview condition than in the list condition. These results supported our hypothesis that a structural overview may hinder the understanding of less knowledgeable readers, because it draws their attention to the textual macrostructure at the expense of attention to the microstructure of the text. 相似文献

The purpose of the investigation is to study changes in intelligence among Swedish 13 year‐olds during a 25‐year period. The results show that the average of spatial and reasoning intelligence has successively risen. Concerning verbal intelligence, there is a clear increase during the 1960's. After this period the growth has been more irregular. No changes in the differences between social groups were observed. On the other hand, this was the case between boys and girls. In verbal ability, there were only small differences between the sexes in 1961. However, in 1985 the girls were clearly ahead of the boys. In spatial and reasoning ability, the boys were superior in the early 1960's. Twenty‐five years later this difference had almost disappeared. 相似文献
