例说走出纠错教学困境的几点感悟     

章珏 《中学数学教学》2005,(6):12-13

面对学生的错误,传统的做法是直接把正确的答案教给学生,因为这样可以节省教学时间,增加课堂训练的密度和强度.但评讲不久便发现,错误又死灰复燃,许多同学依然重复"昨天的故事".究其原因,由于这种评讲没有切入学生解题时犯错的真实情境,评讲缺乏针对性,教学的低效性自然也就显现出来了.  相似文献

Inspirational Reality TV: The Prosocial Effects of Lifestyle Transforming Reality Programs on Elevation and Altruism     

Mina Tsay-Vogel  K. Maja Krakowiak 《广播与电子媒介杂志》2016,60(4):567-586

In light of recent theories of meaningful media that suggest a host of psychological benefits, the present study uniquely extends the boundaries of the effects of reality TV from simply offering pleasure, diversion, and amusement to its viewers to also providing deep insight and meaning. In particular, a between-subjects experiment (N = 143) examined differences in affective, cognitive, and motivational responses to lifestyle transforming versus game based reality programs. Findings indicate that lifestyle transforming reality TV produced stronger feelings of elevation and perceptions of the program as moving and thought-provoking than game reality TV, which in turn increased motivations for altruism. Avenues for future research and theoretical implications of meaningful and inspiring reality TV for positive psychology are discussed.  相似文献   

Smart structures and materials     

V. K. Wadhawan 《Resonance》2005,10(11):27-41

A structure is an assembly that serves an engineering function. It is reasonable to expect that all engineering design should be smart, and not dumb. But one can still make a distinction between smartly designed structures and smart structures. The latter term has acquired a specific technical meaning over the last few decades. A smart structure is that which has the ability to respond adaptively in a pre-designed useful and efficient manner to changes in environmental conditions, including any changes in its own condition; the response is adaptive in the sense that two or more stimuli or inputs may be received as anticipated and yet there is a single response function as per design. Smartness ensures that the structure gives optimum performance under a variety of environmental conditions. While structures with some degree of smartness have been designed from times immemorial, the current activity and excitement in this field derives its impetus from the level of sophistication achieved in materials science, information technology, measurement science, sensors, actuators, signal processing, nanotechnology, cybernetics, artificial intelligence, and biomimetics.  相似文献   

Technical analysis of a Central Asian wall painting detached from a Buddhist cave temple on the northern Silk Road

A great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified.  相似文献   

Does the long tail really favor small publishers?     

Stéphanie Peltier  Françoise Benhamou  Mamoudou Touré 《Journal of Cultural Economics》2016,40(4):393-412

A growing body of literature is devoted to testing the reality of the “long-tail” phenomenon. This literature is mostly, if not exclusively, focused on the impact of Internet on the distribution of sales by product. However, the long tail also raises the issue of a possible change in the usual market structure of cultural industries: an oligopoly with a competitive fringe. To our knowledge, no paper addresses the following question: If the long-tail effect does exist, is it of more benefit to small or dominant publishers? The aim of this paper was to address this issue in the context of the French publishing industry. Our main findings are as follows: (1) the market concentration of the French book industry is lower online than offline and (2) the difference in concentration between the two channels of distribution tended to widen over the period 2004–2010. Strategies adopted by leading publishers on the Web do not allow them to maintain the market share obtained with bricks-and-mortar retailers. Furthermore, we show that the market share lost by dominant firms is captured by small publishers online and by medium-sized publishers in conventional stores.  相似文献
