ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.  相似文献

Public understanding of science as a separate subject in secondary schools in The Netherlands     

Wobbe De Vos  Jurrie Reiding 《International Journal of Science Education》2013,35(7):711-719

This paper describes and analyses an attempt to introduce the public understanding of science as a subject in its own right to be taught to all students in upper secondary education in The Netherlands. The aim of this paper is to make some of the experiences gained in this attempt, especially those related to the development of curriculum content, available to others. As the large-scale implementation of the new subject is still in progress, we focus on the initial stages of the introduction, covering the period 1994-1998. This period includes: (i) the launching of the initiative by a departmental advisory committee; (ii) the subsequent formulation of attainment targets; (iii) a curriculum development project that produced four teaching units tested in classroom experiments and meant as specimens to guide and inspire the authors of schoolbooks; and (iv) the publication of the first schoolbooks on the new subject. We conclude that in spite of its status as a separate subject, the current version of the course does not yet have a clear identity that distinguishes it, in the eyes of students as well as teachers, unmistakably from the traditional science subjects in the school.  相似文献

提出研究假设的作用     

佟德 《教育科学研究》2006,(1):60-61

研究假设是研究课题确定后依据一定的知识、事实和资料,对所研究问题的规律或原因做出的推测性论断和假定性说明,是研究之前预先设想的、暂时的理论,是对研究课题设想出的一种或几种可能的结论或答案。假设一般包括两个事件或概念之间的关系,用“如果……那么……”的句子来陈述。例如:如果教师对一名学生的评价越来越差,那么该生的自我评价也会变得越来越差。研究假设是我们在实施课题研究设计之前,必须明确的问题。在教育科学研究中,提出具体的研究假设具有非常重要的作用。一、为课题研究指明方向研究假设使研究目的更明确,研究范围更确…  相似文献   

浅析青少年生理发育特点与体育教学卫生     

常为来  宫丽娜 《淮南职业技术学院学报》2001,1(1):120-121,124

合理的运动可以起到增强心脏功能，改善呼吸系统功能，提高消化系统功能。不合理的运动将会与之背道而驰。针对青少年身体各器官的生理发育特点，通过对运动系统、心血管系统和呼吸系统、神经系统的生理发育特点以及体育教学卫生等方面的分析研究，认为：在体育教学中，应根据青少年运动系统的卫生，注意青少年心血管系统和呼吸系统的卫生，还应把握青少年神经系统的发育特点，促进大脑皮层兴奋与抑制，均衡发展卫生。  相似文献   

浅析英语教学中的文化渗透     

龚冰 《湖州职业技术学院学报》2007,5(1):71-73

语言是文化的一部分,不能独立于文化而存在。由于不同的民族有着不同的社会文化背景,因此,学习一种语言必须了解这种语言所承载的文化。英语教学中必须注重对学生进行文化渗透,首先,应充分利用现有教材,立足课堂,进行文化渗透,其次,要不断开拓第2课堂,加强文化渗透。  相似文献

传统概念问题的当代形式逻辑剖析     

龚启荣 《黔南民族师范学院学报》2005,25(5):20-25

尽管传统形式逻辑在概念问题上不研究大于1的n元名词而只研究仅占n分之1的1元名词，可是在这n分之1的研究中仍然存在着不少缺陷。譬如，关于概念的定义至今仍不能自圆其说；有些概念种类划分不合理；给概念内涵下的定义产生歧义；给普遍概念下的定义过宽；等等。传统形式逻辑是真正的逻辑科学，我们剖析的目的是深深地切望传统形式逻辑深刻正确的主导思想和久胜不衰的理论成果得到发扬光大。  相似文献
