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。

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.
