浅谈篮球比赛紧张心理的形成及对策

随着篮球运动的不断发展,比赛不仅是技战术及体力的较量,更是知识、智慧、心理素质的较量。但往往因队员过度紧张,心理承受能力差,而导致比赛中动作失常、过度抑制或过渡兴奋、情绪不稳定、注意力不集中的现象,不能充分发挥整体及个人应有的水平,直接影响比赛。就这一方面的有关问题根据多年的教学经验,总结出一些能够消除紧张心理情绪的方法和措施,希望引起同行们的讨论和研究。

The Uncertain Future for Digital Visual Collections in the University

Digital documents in the networked information environment fundamentally change the ways that visual materials can be used in education and scholarly discourse. These new uses raise questions about research library strategies with regard to digitized visual materials as a part of their collections, challenge assumptions underlying intellectual property rights for images and their scope, and offer ways in which visual literacy can become a more integral part of the common educational experience.     

That vision thing.

The 1991 Janet Doe lecturer describes the vision held by the founders of the Medical Library Association of medical information being readily accessible to health professionals no matter how far they were located from major medical centers, and traces the pursuit of this vision to current outreach activities.

Ensuring Content‐Area Learning by Secondary Students with Learning Disabilities

Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively.     

要同中学生谈自爱

当前，有少数中学生不懂得自爱。他们有的自卑，有的自弃，无所事事，无心向学。针对这些问题，德育工作者应该和中学生朋友推心置腹地谈谈自爱，劝导中学生自爱应从下面八个方面做起。１．珍惜自己的身体。身体是学习和工作的本钱，没有一个健康的体魄，就不能进行正常的学习和工作。中学生不仅要注意饮食卫生，保证定时定量，全面摄取营养，满足身体发育的需要，还要按时作息，保证每天有８～９小时的睡眠，积极参加体育锻炼，上好体育课，做好“两操”，讲究用脑和用眼卫生。２．爱惜自己的生命。人最宝贵的东西是生命，生命对于每个人只…     

Early Literacy Skills in African-American Children: Research Considerations

The poor reading achievement of African-American children in urban schools is well established. African-American children from low-income homes may be at particular risk for reading difficulties, although middle-income children often fare poorly as well. Intervention efforts have focused on children in kindergarten through fifth grade. This article suggests that prevention efforts must begin prior to kindergarten entry. Several key variables that may influence young children's performance, including poverty, general oral language skills, dialectal variations, home literacy practices, standardized testing bias, and teacher expectations, are explored. Future directions for research addressing emergent literacy in African-American children are discussed throughout.
