Racial Perceptions of Young Children: A Review of Literature Post-1999     

Dean Cristol  Belinda Gimbert 《Early Childhood Education Journal》2008,36(2):201-207

It has been argued that intervention strategies designed to reduce racial prejudice in young children have been based on weak theoretical models of racial stereotyping and prejudice with little effect on the reduction of racial bias. This paper examines the social-cognitive and intergroup scholarship post-Bigler (J Soc Issues 55(4), 687–705, 1999), with an emphasis on the development of racial prejudice in young children. The purpose of this paper is not to argue for a particular theoretical approach, but to provide an overview of some of the important pieces of research. Findings indicate that social learning and cognitive development models need to be understood when implementing curriculum designed to reduce racist beliefs and attitudes in young children.  相似文献   

技术发展与业务需求双驱动下的物联网演进     

彭聪  罗德安  夏林中  许志良 《深圳信息职业技术学院学报》2021,(1)

伴随着信息与通信领域的关键技术以及产业背景下新型业务需求的发展,物联网的关注重点、关键支撑技术以及服务形式都在持续地变化。自20世纪90年代末物联网概念被提出至今,物联网的代际演进可以系统地梳理为具有不同特征的三个阶段,包括注重物体标记的初代物联网、注重物体联网的二代物联网以及引入了社交网络的新型社交物联网。为了构建完整的物联网系统,应深刻地理解技术发展和产业需求是如何驱动物联网的代际演进,并在此基础上,谋求关键技术的选用和协同,以提供适应物联网设备和应用特征的解决方案。  相似文献

Power and energy in linearized physical systems     

Dean Karnopp 《Journal of The Franklin Institute》1977,303(1):85-98

Although no truly linear physical systems exist, linearized system models are very often used in practice to study the dynamics of real systems and components. Here, the relations between the power and energy in a non-linear physical system and the analogous quantities associated with variables representing small deviations from steady-state values are studied. Sometimes a linearized system is energetically similar to the non-linear system from which it was derived, and in other cases, new types of energy elements appear which were not present in the original system. In order to show the structure of the systems, the results are presented in both equation form and in the form of bond graphs which are unique in exhibiting the power and energy structure of system models.  相似文献

一定的学校管理模式总是与一定的学校发展水平相适应。当学校发展处于较高阶段的情况下,需要构建学习型学校管理模式,使之与较高层次的学校发展阶段相适应。一所学校的生存与发展并不仅仅是由物质条件和师资水平决定的,学校发展的关键指标--学校的核心精神,起着重要的作用。必须在组织结构和知识载体两方面构建平台,对学习型学校建设提供支持。  相似文献   

“人的全面发展”内涵新析   总被引：58，自引：0，他引：58  

扈中平 《教育研究》2005,(5)

把握“人的全面发展”内涵的实质,应确立两个理论前提:第一,“人的全面发展”在很大程度上是一种理想、一种追求、一种社会和人生的信念;第二,“人的全面发展”是一个相对的概念,而不具有绝对的意义。同时,“人的全面发展”还应包含四个层面的内涵,即完整发展、和谐发展、多方面发展、自由发展。  相似文献   

Response bias in follow-up studies of college students     

H. Dean Nielsen  Dr. Rudolf H. Moos  Elisabeth A. Lee 《Research in higher education》1978,9(2):97-113

The problems of response bias in longitudinal studies of college students are examined. An extensive follow-up questionnaire was sent to 1,253 college seniors who had participated in a similar survey as freshman four years earlier. Careful measure of student responsiveness in relation to various techniques designed to increase the proportion of responders (e.g., postcard, telephone contact) were kept.The less responsive groups were significantly different from their more responsive counterparts on nearly a dozen variables representing a wide variety of content areas, including academic achievement, self-concept, alcohol consumption, social deviance, and major choice preferences. Controlling for sex and socioeconomic status served to reduce, but not eliminate, these biases. Overall, the results indicate that researchers cannot account for follow-up nonresponse bias by making statistical adjustments according to data available at initial testing. The results are discussed in light of identifying the reasons for nonresponse, and attempting to develop categories of nonresponders who may be motivated to cooperate by different types of follow-up techniques.  相似文献

刘复兴 《教育研究》2006,(9)

有效解决我国义务教育改革发展面临的重大问题是修订1986年《义务教育法》的根本动因。新《义务教育法》在义务教育法的立法目的、义务教育的基本性质、经费投入、政府责任、学校安全、教育公平与均衡发展、教师队伍、法律责任等方面都有一些新的、重大的突破。这部《义务教育法》是我国义务教育立法和义务教育发展进程中的一个新的里程碑。  相似文献   

Changing primary teacher trainees' attitudes to science     

Beverley Jane  Associate Professor Marjory-Dore Martin  Russell Tytler 《Research in Science Education》1991,21(1):188-197

A study of primary teacher trainees' perceptions and attitudes to science in 1990, has been useful in designing a semester unit aimed at increasing the confidence and interest of first year students at Victoria College. This paper outlines the background survey and discusses some, of the results and how they were used to develop the Professional Readiness Study-Understanding Science. This unit attempts to change attitudes by focussing on metacognition and encourages students to understand and control their own learning. Discussion involves teaching and learning strategies and alternative assessment approaches including the student's journal-the Personal Record. Specializations: technology for learning, health education. Specializations student understanding of biology, particularly genetics, evaluation. Specializations: children's learning in science, language in science.  相似文献   

课程改革与教学模式转变   总被引：24，自引：0，他引：24  

段作章 《教育研究》2004,(6)

新一轮基础教育课程改革以空前的力度和崭新的面貌令世人关注,要实现课程改革的预期目标,关键在于教学模式的转变。现行教学模式必须从教师本位向学生本位转变,从独白式教学向对话式教学转变,从封闭式向开放式转变,从传递接受式教学向以引导探究为主要特征的多样化教学转变。  相似文献
