重视学生特性,实现思想政治课教育功能最大化

促进人的个性发展是教育长期追求的重要目标。思想政治课在学校的课程体系中居于首要位置,在提高学生的文化素养、道德修养及促进学生的个性发展等方面发挥着不可替代的作用。而艺术院校的学生在个性及其专业特性上具有明显的特点,因而,在思想政治课教育中,重视和利用教育对象的特殊性并将其与教育活动紧密联系,使教育活动自觉反映并符合学生身心发展的需求、学生的个性发展与教育活动趋向良性互动的状态,实现艺术院校思想政治课教育功能最大化的目标。     

Learning executive function skills by playing focused video games

The objective of the present study was to determine whether it is possible to design a video game that could help students improve their executive function skill of shifting between competing tasks and the conditions under which playing the game would lead to improvements on cognitive tests of shifting. College students played a custom video game, Alien Game, which required the executive function skill of shifting between competing tasks. When students played for 2 h over 4 sessions they developed significantly better performance on cognitive shifting tests compared to a control group that played a different game (d = 0.62), but not when they played for 1 h over 2 sessions. Students who played Alien Game at a high level of challenge (i.e., reaching a high level in the game) developed significantly better performance on cognitive shifting tests compared to controls when they played for 2 h (Experiment 1, d = 1.44), but not when they played for 1 h (Experiment 2). Experiment 3 replicated the results of Experiment 1 using an inactive control group, showing that playing Alien Game for 2 h resulted in significant improvements in shifting skills (d = 0.78). Results show the effectiveness of playing a custom-made game that focuses on a specific executive function skill for sufficient time at an appropriate level of challenge. Results support the specific transfer of general skills theory, in which practice of a cognitive skill in a game context transferred to performance on the same skill in a non-game context.     

逻辑思维在法律文书语言运用中的重要性

＂以事实为根据,以法律为准绳＂是我国司法机关办案的指导原则,用精确的逻辑思维指导法律语言实践是法律文书具有说服力的基础。而逻辑思维以概念、判断、推理为其反映形式,本文拟从这三方面对逻辑思维在法律文书语言运用中的重要性加以分析、探讨。     

公共英语新版教材编写体验与认知

为了更好地配合和适应我国公共英语等级考试和教学的发展需要，新版公共英语教材经过重新编写即将面世。该系列教材在第一版的基础上无论从指导思想、内容、以及编排体例上都做出许多新的变化，内容选材上更加注重时代感、启发性、实用性和文化性，编排上追求系统性，科学性，开放性，以及可操作性。全书融入许多新的教学理念，必将更好地应用与服务于我国公共英语教学的实践。     

休闲与物理学创造的双向互动性

休闲是科学诞生的基本条件之一。作为时间形态存在着的休闲（闲暇时间）是物理学创造活动得以进行的基本保证,而作为实践形态而存在的休闲则极大地推动了物理学的突飞猛进,并通过技术的中介,给人类社会带来了高度的物质文明和精神文明,反过来在延长了休闲时间的同时,又丰富了休闲的内容与方式。在当今知识爆炸时代与信息化时代,无论是对任何一门学科的教学而言,学校主管部门特别是具体授课者,都应该力求做到得心应手地给学生＂留下空间＂。因为只要有了空间,学生就不仅能够在积极向上、形式各异、多姿多彩的校园文化这个心灵的驿站中,获得精神的慰藉,从而陶冶了情操、恢复了体能、增强了交际能力;而且还能够充分利用课余的闲暇时间,在开放性、交互性、共享性、协作性和自主性的信息化环境中,积极主动地去猎取适合发展自己个性特长的有关知识,进而使他们的知识结构,能够跟得上新知识、新学科与日俱增的时代步伐。     

异议模式及其语用功能探究

在交流日益频繁的今天,表达异议也日显重要。作为一种本质上不合作、不礼貌的重要言语行为,异议却往往容易被研究者忽视。基于异议在日常交往、辩论访谈等活动中的实证分析,可以尝试对其主要模式进行分类,探讨不同模式的语用功能。并且为了便于实践中表达异议时模式的选择,影响选择的强弱、显隐、直接间接三对参数被提出。研究旨在补充异议这一言语行为在语用学中的研究,促进人们更好地交换意见。     

Improving cognitive and physical function through 12-weeks of resistance training in older adults: Randomized controlled trial

ABSTRACT

We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults.     

Creative Potential within Policy: An Analysis of the 2013 English Literature Curriculum

This article takes as its focus Lefebvre's trialectic of conceived, perceived and lived spaces as a lens through which to scrutinise the 2013 English Literature Curriculum, and to explore the extent to which creative spaces might exist within that curriculum. The article analyses how the curriculum is envisaged by policymakers and how it might be expected to be translated into practice, utilising the wording of the policy document to facilitate an exploration of what its underlying intentions might be. The author's experience of teaching a poem from the new curriculum is used in order to provide illustrative examples of the ways in which teachers’ and learners’ experiences of the curriculum might, in practice, diverge from the direction envisaged by policymakers as teachers negotiate creative spaces within their classrooms.     

试论中国古典音乐的崇高美——以《十面埋伏》为例

艺术作品的崇高美,是指艺术作品本身蕴含着庄严伟大的思想,强烈激动的情感、雄奇远大的意象、激越高昂的格调、慷慨激昂的旋律、跳跃夸张的结构、恢宏阔大的场面、饱满奔放的语言。中国古典音乐中崇高美质的最大作用是振奋人们的精神。
