Students’ choice of animated pedagogical agents in science learning: A test of the similarity-attraction hypothesis on gender and ethnicity     

Roxana Moreno  Terri Flowerday 《Contemporary educational psychology》2006

College students learned about science with a multimedia program. One group (choice or C) chose to learn with or without an animated pedagogical agent (APA) representing a male or female of five different ethnicities. Another group (no-choice or NC) was assigned an APA by the system. All participants in C group chose to learn with APAs and students of color chose significantly more same-ethnicity APAs than White American students. A significant interaction between choice and ethnic similarity factors revealed that group C produced lower retention, transfer, and program ratings when learning with same-ethnicity rather than different-ethnicity APAs. Results support an interference hypothesis for students who choose to learn with same-ethnicity APAs.  相似文献   

健美操动作的灵魂--论健美操音乐的选配   总被引：1，自引：0，他引：1  

李萍 《湖南第一师范学报》2005,5(1):66-67

健美操的音乐是健美操动作的灵魂，音乐和动作的和谐统一是一套健美操完美表现的标志，因此音乐的选配对动作的节奏、风格、整体布局及表现起着决定性的作用。同时在选配健美掺音乐时我们应特别注意音乐的延续性和完垫巨，此外音乐的风格、节奏和旋律决定着健美操动作的编排及表演者的再创造。  相似文献   

陕西秦岭旅游景区认知与选择偏好研究     

田祥利  宋保平  延军平 《资源科学》2010,32(5):873-879

在大尺度区域旅游规划兴起背景下,本研究以陕西省秦岭旅游发展专项规划为例,基于客源群体差异角度,运用认知度和偏好度等值线图对大区域旅游景区认知和选择偏好规律进行了探究,结果表明：①成熟型和稳定型旅游景区形成认高知度聚集区,成长型和开发型旅游景区形成低认知度分散区;②旅游景区选择偏好形成聚集区和辐射区,数量选择偏好存在差异,旅游景区空间显示偏好与交通通达性密切相关;③大区域旅游景区认知度和选择偏好度存在正相关关系,形成了以认知为基础的旅游景区偏好和出游倾向。  相似文献

县域生态工业园区发展路径选择     

刘仕欣 《安阳师范学院学报》2009,(2):106-109

县域经济发展生态工业是循环经济的必然选择,生态工业园区是县域生态工业的主要载体。生态工业茵区有虚拟型、现有改造型和全新创建型三种建立模式。目前,县域经济构建生态工业园区存在物质集成障碍、技术障碍、信息共享障碍、效益障碍和政策障碍等障碍,因此需要进一步制度创新。  相似文献

炳灵寺石窟与丝绸之路东段五条干道     

李并成  马燕云 《家教指南》2010,(2)

炳灵寺石窟地处古丝绸路上的一大"山结"、"水结"之处,亦为"路结"所系之地,丝路东段五条干道——秦陇南道、羌中道(吐谷浑道)、唐蕃古道、大斗拔谷道、洪池岭(乌鞘岭)道,在其附近一带汇聚。本文通过该石窟中留存的大量游人题记等有关史料的研究,对其在丝路交通上的重要地位作了新的揭示和剖析,并为该石窟作为丝绸之路整体"申遗"入选的重要景点之一提供新的历史依据。  相似文献   

Why are there proportionately more poor pupils enrolled in non-state schools in urban Kenya in spite of FPE policy?     

Moses Oketch  Maurice Mutisya  Moses Ngware  Alex C. Ezeh 《International Journal of Educational Development》2010,30(1):23-32

One of the conundrums of free primary education (FPE) policy in several countries in Sub-Saharan Africa is the ‘mushrooming’ of fee-paying private schools. Several researchers have become interested in studying this phenomenon and have raised the question—does free primary education meet the needs of the poor? Emerging voices among this group of researchers suggest that the impact of FPE, particularly in meeting the educational needs of the poor may be over-stated in situations where the poor still utilize what is referred to as ‘private schools for the poor’. The concerns expressed by those voicing this point of view point to the question of why the poor choose fee-paying [low quality] private schools when there is, presumably a free state school? To respond to this question and to contribute to this debate, this paper adopts the excess demand and differentiated demand frameworks to analyse how slum (poor) and non-slum (non-poor) parents utilize education in Nairobi, Kenya following the implementation of free primary education policy in 2003. We conclude that the answer to the ‘mushrooming’ of private schools for the poor is ‘excess demand’. As to whether free primary education meets the needs of the poor, we argue that where supply does not match demand excess demand is likely to arise in the initial stages. We recommend that what is required is greater and possibly differentiated and better targeted investment in education whereby unequals are treated unequally in order for the Kenyan government not to under-invest in the education of the poor.  相似文献   

理性选择理论视角下的身份认同研究     

韦岚 《四川职业技术学院学报》2009,19(3):27-29

理性选择理论在社会学、公共行政和公共管理等领域产生了丰富的理论成果,其对个人行为选择的分析着重运用系统方法进行研究,以达到解释行为发生原因,预测行为前景的效果.这在个人确立身份并建构身份认同的过程中发挥了重要的指导作用,通过引导个人在差异申确定身份,从语言、文化、记忆等层面完成身份建构,避免个人因在身份认同上与群体的偏离而产生发展的滞后性,在思想上和行动上实现个人的身份认同,彰显人生的价值与意义.  相似文献   

基于dijkstra算法的农网路径优化     

项川  冯宁  汪谦 《人天科学研究》2013,(1):51-53

在线路设计中路径的选择极甚为关键的环节,它会严重影响工程的总造价和运行的稳定性。根据送电线路路径选择上的一些特点,建立在全局基础上最优的路径搜索模型,并且把地质情况、水文状况和林带等影响线路的路径选择的因素统统包括在内,最后运用dijkstra算法在模型上进行最优路径搜索。仿真结果说明,dijkstra算法可以正确地计算出全局最优路径。  相似文献
