现代管理学的发展已经由科学管理向文化管理转变。在中国学前教育发展中民办幼儿园占主要市场,国家投入少,生源竞争激烈,办园质量良莠不齐,民办幼儿园只有"以人为本"进行文化管理,办出特色,打造品牌,才能赢得良好的社会效益和经济效益。而幼儿园文化管理的实质就是幼儿园的文化建设,因此加强民办幼儿园的物质文化、制度文化、精神文化建设是其可持续发展的重要途径。 相似文献

From 1996 to 1999, an inclusive early special educational model was studied in 13 ordinary kindergartens in Finland. The kindergartens received an additional staff member (a special teacher) to handle special educational issues. The work of these special teachers and the views of the staff were studied. The special teachers' duties consisted of six main tasks, the most often mentioned being general and special educational work and consultation with adults. The staff were generally satisfied with the new system. They received assistance and learnt new ways of working. However, the special teacher did not have enough time to meet all the needs that existed in kindergartens. This experimental model is now a permanent system. 相似文献

Kindergarten children's perception of play is a reflection of their life and experiences, which can be used as an index of the quality of pre‐school provision and the influence of kindergarten education reform that began in the 1980s in mainland China. Therefore, based on this hypothesis, the current authors argue that to examine young children's perceptions of play is to examine the experiences of their life in kindergarten and, indirectly, the effects of kindergarten education reform. Using photo classification and on‐site interviews, the current research explored 5‐ and 6‐year‐old children's perceptions of play. This article reports on research comparable to previous research which aimed to examine the effect of the 15‐year kindergarten education reform. One of the principles which the reform advocated was that kindergartens and early years practitioners should respect young children's rights to play, emphasizing and providing play over group lessons as the basic activity in kindergarten settings. Similar to the results of previous research, the current research showed that group lessons remained the main reference used by young children to judge the nature and meaning of activities in kindergartens. However, the activity in the interest corners/areas, which has been a main method of organizing children's activities in kindergartens advocated by the top‐down approach to kindergarten educational reform since 1989, was found to be a new criterion in young children's judgements. The current research revealed that kindergarten education reform had achieved some positive effects as expected. 相似文献

Being taught to learn together: an ethnographic study of the curriculum in two Chinese kindergartens
Fengling Tang Shirley Maxwell 《Early Years: An International Journal of Research and Development》2007,27(2):145-157
This paper reports the findings of a pilot study which adopted an ethnographic approach to investigate the cultural features of the Chinese kindergarten curriculum by means of ‘semi‐participant’ observations, semi‐structured interviews, daily conversations and open‐ended questionnaires in two Chinese kindergartens. The paper first introduces the debate over teaching and learning in the early years in Western contexts. It then demonstrates that the curriculum in Chinese kindergartens is mainly implemented by means of teachers' formal collective teaching. Children seem to be taught to learn; their spontaneous learning interests are welcomed but seldom developed in depth. The preference among teachers for this formal collective teaching, coupled with their perception that this teaching is required in their particular situations, creates a tension between teaching and children's learning. The shift in parents' views of education, from an over‐emphasis on children's knowledge‐based study to support for children's harmonious overall development, also contributes to this tension. 相似文献
