以知引趣活跃思维——谈中学英语课堂教学的趣味性     

胡威克 《基础教育研究》2002,(3):33-34

要使课堂教学有趣味决非易事，它是一门学问，又是一门艺术。它要求教师具有扎实的教学功底，开阔的眼界和渊博的知识。趣味，顾名思义，是有趣且可回味。决非为了轻松一下，一笑了之，更不是搞噱头，哗众取宠。苏联教育学家科罗寥夫说过：“有趣味、有吸引力的东西使识记可能性几乎增加一倍半，这就是教育的潜力所在。”显而易见，趣味不是目的，而是一种策略。目的是为了营造一个热气腾腾、生动活泼、轻松愉快的学习环境。把书教得趣味盎然是为了充分挖掘学生的学习积极性、主动性和创造性，使其“记忆的可能性”增加，最终达到熟练自如地…  相似文献

Environmentally-induced stone decay: the cumulative effects of crystallization–hydration cycles on a Lincolnshire oopelsparite limestone     

Belinda J. Colston  David S. Watt  Helen L. Munro   《Journal of Cultural Heritage》2001,2(4)

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay.  相似文献
