集体主义与个体主义文化的概念是西方学者在20世纪70、80年代提出,最近十几年来备受争议.研究表明,这种差异实际上反映的是文化或外部环境要求的差异,而不是人类道德心理普遍的本质倾向.在儒家学说和亚洲价值观中同样有民主、权利等政治思想.对亚洲青少年关于权利和民主决策的推理研究表明,东西方青少年的道德推理并不存在显著文化差异,即使在中国文化内部,青少年的道德推理也不存在城乡差异.这表明,自主、权利和民主的概念来源于人类普遍的心理需求. 相似文献

随着网络游戏产业的兴起及不断发展,围绕着网络游戏虚拟财产产生了许多纠纷,造成了网络游戏运营商及大量网络游戏用户的损失。由于有关网络游戏虚拟财产的法律属性未明确规定,致使对网络游戏虚拟财产的法律保护处于真空状态。本文通过对网络游戏虚拟财产的法律属性的探究,认为网络游戏虚拟财产具有物的一般特性,可规定为特定的无体物,并建议制订相关的法律予以保护。 相似文献

This paper focuses on a training program in inductive reasoning for first-grade students and presents the direct results as well as the longitudinal effects of the evaluation study. The training is based on Klauer's theory of inductive reasoning and on his “Cognitive training for children” concept (Klauer, 1989a). The training program consists of 120 problems which can be solved through inductive reasoning. The tools for the training exercises were selected to correspond with the age of the targeted cohort. The experimental group in the study consisted of 90 students, whereas the control group was made up of 162. An inductive reasoning test was used in the pre- and posttest as well as in the follow-up study (one year later). The test comprised 33 figural, non-verbal items (Cronbach α = .86). On the posttest, the experimental group significantly outperformed the control group by more than one standard deviation. The experimental group scored significantly higher in each skill area targeted by the training. The most noticeable development was found in system formation. No gender differences were detected on the pre- or the posttest. The effect size of the training program was d = 1.12. In the follow-up study, the experimental group still significantly outperformed the control group; however, their respective levels of development had not changed in this one-year period. Thus, the training effect proved to be stable over time independent of individual students’ original level of inductive reasoning. This study provided evidence that inductive reasoning could be developed very effectively at this early age. 相似文献

类比推理是一种常用且科学的研究方法,长期以来在数学教学中得到普遍应用,他不仅是数学教学中的重要内容,更是高中数学考试中受到命题人热爱的一大考点。类比推理是一种以两个事物的某些相同属性作为判断前提,以试图找出更多其他属性方面的相同点的推理方式,同时也是一种从特殊推向特殊的推理方法。对学生的实际研究能力和判断推理能力以及相关的思维发散都能取得很好的培养作用,在高中数学教学实践中更是起着非常重要的作用,为教学注入新活力的同时又能为学生的解决问题提供新的思维模式。 相似文献

This study used a large-scale cluster randomized longitudinal experiment (N = 719; 35 schools) to investigate the effects of online mathematics mini-games on primary school students’ multiplicative reasoning ability. The experiment included four conditions: playing at school, integrated in a lesson (Eschool), playing at home without attention at school (Ehome), playing at home with debriefing at school (Ehome-school) and, in the control group, playing at school mini-games on other mathematics topics (C). The mini-games were played in Grade 2 and Grade 3 (32 mini-games in total). Using tests at the end of each grade, effects on three aspects of multiplicative reasoning ability were measured: knowledge of multiplicative number facts, skills in multiplicative operations, and insight in multiplicative number relations and properties of multiplicative operations. Through path analyses it was found that the mini-games were most effective in the Ehome-school condition, where both students’ skills and their insight were positively affected as compared to the control group (significant ds ranging from 0.22 to 0.29). In the Eschool condition, an effect was only found for insight in Grade 2 (d = 0.35), while in the Ehome condition no significant effects were found. Students’ gameplay behavior (time and effort put in the games) was in some cases, but not always, related to their learning outcomes. 相似文献
