Many middle schools use the Web to disseminate and gather information. Online barriers often limit the accessibility of the Web for students with disabilities. The purpose of this study was to evaluate the accessibility of home pages of a sample of middle schools. The authors located 165 Web sites using a popular online directory and evaluated the sites for accessibility. A software program quantified the number of accessibility errors at each site. Most middle school home pages had accessibility problems, and the majority of them represented severe concerns that should be given a high priority for improvement. The good news is that the majority of the errors can easily be corrected. The work reflects a need for middle schools to continuously examine the accessibility of their home pages. Direction for improving accessibility is provided.  相似文献   

Neuroscience,education and the evolution of the human brain     

Richard Aldrich 《History of education》2013,42(3):396-410

This article has two purposes. The first is to bring current developments in neuroscience, including educational neuroscience, to the attention of historians of education. The second is to demonstrate how historians of education, in common with philosophers, psychologists and sociologists, can contribute to this new field. Education has replaced natural selection in human evolution. Symbolic representations, speech, memory, writing, printing, screen-based communications and various mood-changing activities have shaped and are continuing to shape the human brain. It is argued here that by taking a longer historical perspective and recognising the brain as a palimpsest or kluge, historians of education can help to explain the limitations of neuroplasticity and some of the fundamental problems that beset formal educational systems. Just as education needs to be afforded a more central role in the history of human evolution, so the brain needs to be given a more central role in the history of education.  相似文献   

Experimental evidence for improved neuroimaging interpretation using three-dimensional graphic models   总被引：1，自引：0，他引：1

Three-dimensional (3D) or volumetric visualization is a useful resource for learning about the anatomy of the human brain. However, the effectiveness of 3D spatial visualization has not yet been assessed systematically. This report analyzes whether 3D volumetric visualization helps learners to identify and locate subcortical structures more precisely than classical cross-sectional images based on a two dimensional (2D) approach. Eighty participants were assigned to each experimental condition: 2D cross-sectional visualization vs. 3D volumetric visualization. Both groups were matched for age, gender, visual-spatial ability, and previous knowledge of neuroanatomy. Accuracy in identifying brain structures, execution time, and level of confidence in the response were taken as outcome measures. Moreover, interactive effects between the experimental conditions (2D vs. 3D) and factors such as level of competence (novice vs. expert), image modality (morphological and functional), and difficulty of the structures were analyzed. The percentage of correct answers (hit rate) and level of confidence in responses were significantly higher in the 3D visualization condition than in the 2D. In addition, the response time was significantly lower for the 3D visualization condition in comparison with the 2D. The interaction between the experimental condition (2D vs. 3D) and difficulty was significant, and the 3D condition facilitated the location of difficult images more than the 2D condition. 3D volumetric visualization helps to identify brain structures such as the hippocampus and amygdala, more accurately and rapidly than conventional 2D visualization. This paper discusses the implications of these results with regards to the learning process involved in neuroimaging interpretation.  相似文献   

运动中快乐的形成机制与生物学基础     

田聚群  李忠  李铁钢 《精武》2012,(14):1-2

从建立快乐的概念出发,归纳出运动的动机：因为运动可以使人体验列快乐,所以人们才会喜欢并享受运动。根据中枢神经系统的调控对象不同,我们可以将运动项目分为三种类型,并指出不同种类的运动项目所产生的快乐在形式上是相同的。中枢神经采统可塑性为快乐的产生创造了相应的条件。  相似文献

运动疲劳对大脑随意运动控制的影响     

侯莉娟  宋争  于勇  朱凌泽  王君 《北京体育大学学报》2012,35(3):71-74

目的:观察运动疲劳前后,随意运动执行阶段脑区激活情况,探讨运动疲劳中枢调控的机制。方法:采用全脑功能磁共振成像(fMRI)技术,在7名健康男性大学生一次性功率自行车力竭运动前后,进行手握拳运动阶段大脑功能活动的扫描。数据经过头动校正、空间标准化、高斯平滑等预处理后,通过相关分析获得随意运动阶段脑激活图,采用SPM软件对参与随意运动的脑区进行解剖定位,并对运动疲劳前后参与调控的脑区进行配对样本t检验组间分析,寻找激活程度发生变化的脑区。结果:运动疲劳前后非利手执行握拳随意运动时大脑激活位点分别包括对侧初级感觉运动区、双侧运动前区、辅助运动区、小脑、丘脑、岛叶、纹状体及苍白球等,激活位点没有显著差别。但运动疲劳前激活程度显著高于运动疲劳后的脑区包括同侧基底神经节的丘脑和纹状体。利手执行握拳随意运动时大脑激活位点及激活量没有显著差异。结论:运动疲劳对参与随意运动控制的脑区位点没有显著的影响,但是同侧基底神经节的纹状体和丘脑参与调控的激活程度发生显著变化。  相似文献   

视觉空间认知加工的可塑性及其对特殊教育的启示     

晏碧华  游旭群 《南京特教学院学报》2007,(3)

可塑性是指有机体在环境反应过程中其结构和功能的可变性和突变性。行为可塑性的研究主要表现在对行为的形成与发展、行为自动加工的获得性及其影响因素的考察,行为可塑性是以脑结构的可塑性为基础。视觉空间认知加工的可塑性研究可通过检验训练效应和年龄效应而得以实现,多种视觉空间认知加工的可塑性存在差异。可塑性的研究提示:教育具有长时功效性和终生性。而视觉空间认知加工的可塑性研究则提示:选择性地进行特殊领域的系统训练可使特殊儿童的康复训练达到事半功倍的效果。  相似文献
