说起雷峰塔,有人会想起《白蛇传》里的神话传说,有人会想起鲁迅先生那篇刊登于中学课本的杂文《论雷峰塔的倒掉》。始建于五代十国的雷峰塔曾是西湖的地标建筑,“雷峰夕照”是著名的西湖十景之一。1924年9月25号雷峰塔轰然坍塌。2002年10月25日,雷峰塔重建竣工。2008年4月18日至2009年5月31日,“刀锋——重建雷峰塔”实验艺术展在北京圣之空间展出,宣誓着来自西湖边的艺术理想和精神之塔的重建。 相似文献

The present, study was conducted to determine the level of malondialdehyde (MDA) as an index of free radial induced lipid
peroxidation and antioxidant vitamins-vitamins A, vitamin C and vitamin E in 75 confirmed cases of urolithiasis. Significantly
high level of MDA (p<0.001) with significantly low levels of vitamin E (p<0.001) and vitamin A (p<0.001) with no significant
decrease in vitamin C (p>0.05) were observed in the plasma of urolithiasis cases as compared to normal controls. In conclusion,
it appears that a role of lipid peroxidation and oxidative function exists in the pathogenesis of urolithiasis. But, the exact
mechanism how this occurs remains to be elucidated. 相似文献

This article seeks to understand the ways in which feedback was communicated in post-observation conferences in teaching practice supervision within the learning-oriented field experience assessment (LOFEA) framework. 32 post-observation conferences between 21 pairs of supervisors and participants of in-service teacher education programmes, and interviews with supervisors and participants were analyzed, with findings revealed in four themes:
- 1.
- The distribution of content and nature of feedback in post-observation conferences; 相似文献

This study describes the process of defining a hypothetical learning progression (LP) for astronomy around the big idea of Solar System formation. At the most sophisticated level, students can explain how the formation process led to the current Solar System by considering how the planets formed from the collapse of a rotating cloud of gas and dust. Development of this LP was conducted in 2 phases. First, we interviewed middle school, high school, and college students (N?=?44), asking them to describe properties of the current Solar System and to explain how the Solar System was formed. Second, we interviewed 6th-grade students (N?=?24) before and after a 15-week astronomy curriculum designed around the big idea. Our analysis provides evidence for potential levels of sophistication within the hypothetical LP, while also revealing common alternative conceptions or areas of limited understanding that could form barriers to progress if not addressed by instruction. For example, many students' understanding of Solar System phenomena was limited by either alternative ideas about gravity or limited application of momentum in their explanations. Few students approached a scientific-level explanation, but their responses revealed possible stepping stones that could be built upon with appropriate instruction. 相似文献

Kenya experienced a severe drought and temporary food shortage during a study on mild malnutrition. Effects of the temporary food shortage on energy intake, weight, and behaviors were evaluated in schoolchildren and in toddlers and their mothers. Schoolchildren were seriously affected, showing significant declines in their energy intake, age-corrected weight, activity on the playground, and classroom attention. Toddlers appear to have been somewhat protected since their energy intake, weight, and play and language behaviors were stable. Maternal caregiving of toddlers declined for the group as a whole, but individually those mothers who maintained family food levels delegated responsibility for toddlers to other caregivers. While the food shortage affected poorer families more than those of higher SES, declines in the behaviors of schoolchildren occurred regardless of SES and previous level of nutrition, suggesting that food shortages can have behavioral consequences for schoolchildren in all communities. 相似文献

Using mathemagenic-based research, the authors attempted to determine if the location or type of a picture affects reading
comprehension. College students read a passage and then answered multiple-choice questions that assessed different types of
incidental learning. Generally, subjects who viewed a picture after reading the passage scored higher than those who viewed
before reading. 相似文献

This qualitative study was conducted to discuss and dispel commonly held myths about Latino parents' involvement in their children's education. Differences between teacher perceptions of Latino parent involvement and parents' understanding of their roles in supporting their children's education—including the learning and use of the English language—were explored. Results indicated that some teachers held negative perceptions of Latino parents. The study also revealed that Latino parents had high expectations of their children's academic achievement and wanted to be more involved in their education, but felt excluded from the school community. 相似文献
