我国退役奥运会冠军社会流动研究

研究运用文献资料法和数理统计法,分析我国退役奥运会冠军的社会流动情况,主要从代际流动和代内流动两方面探讨了导致我国退役奥运会冠军社会流动的原因,研究发现:我国退役奥运会冠军社会流动以向上流动为主。并且发现我国退役奥运会冠军社会流动受社会环境、家庭因素和其他个人自致因素的影响,其中,家庭因素对我国退役奥运会冠军的社会流动影响最大。     

浅谈太极拳教学在农村中小学体育教学中的应用

太极拳是一种体育运动,也是一种武术,更是一种强身健体的项目,在中国有着悠久的历史。农村中小学把太极拳作为传统项目的教材,在很多方面有很大的推广价值。为进一步探索农村中小学体育特色工作的新思路,高标准推进教育教学工作,我们选择了太极拳训练为体育特色。笔者常年从事体育教学,对太极拳教学有着丰富的教学经验,如何在农村中小学体育教学中打好太极拳我感觉至关重要。太极拳不仅能强身健体还能培养学生的情操,提升校园文化建设,更能磨炼学生的意志,树立正确的人生观和价值观,本文对太极拳教学在农村中小学体育教学中的认识提出了自己的观点。

Coeducational and single-sex physical education: students’ situational interest in learning tasks centred on technical skills

Background: A student’s choice to engage in a learning task is highly related to the student’s environmental stimuli and his or her perception of interest. From this perspective, the construct of situational interest (SI) has been used to interpret students’ motivation in task engagement. SI is assumed to be transitory, environmentally activated, and context specific. It has been conceptualized as a multidimensional construct with five dimensions: instant enjoyment, exploration intention, attention demand, novelty, and challenge. Few prior studies have compared SI between girls and boys in physical education (PE) contexts, and these studies have offered contrasting findings. They were conducted in coeducational (coed) or single-sex contexts and used learning tasks centred on a variety of outcomes: technical or tactical skills, creativity and cultural understanding.

Purpose: In the context of the debate on single-sex and coed classes in PE, this study aimed to estimate the effects of single-sex and coed PE classes on students’ situational interest (SI) within learning tasks centred on technical skills. The researchers decided to study learning tasks centred on the development of students’ technical skills, since these tasks are often used by teachers in PE.

Participants: The sample consisted of 177 Swiss secondary school students, aged 11–17 years (M?=?14.07, SD?=?1.41, 96 boys, 81 girls).

Data collection: The students completed the French 15-item SI Scale after practising a technical learning task in single-sex and coed PE contexts. The researchers chose five physical activities (i.e. athletics, basketball, dance, gymnastics, and volleyball), which are commonly taught in the state of Vaud (Switzerland) and provide a balance between masculine and feminine activities.

Data analysis: A two-way repeated-measures MANOVA was performed to examine the main and interaction effects of student sex and class sex composition on the five SI dimensions.

Findings: The results showed a main effect of class sex composition on student SI but no main effect of student sex and no interaction effect of student sex and class sex composition. More precisely, the scores for three SI dimensions (i.e. instant enjoyment, exploration intention, and attention demand) were higher in the coed context than in the single-sex context.

Conclusions: This study encourages teachers to propose coed PE classes to enhance students’ motivation and engagement when practising learning tasks centred on technical skills. This study offers supplementary evidence of the teacher’s role in promoting student SI. Beyond accounting for students’ dispositional factors (e.g. sex), PE teachers can significantly impact students’ SI in technical learning tasks through instructional choices.     

班级:初级群体还是社会组织——一个教育社会学论争的实证性解释和结论

应用社会网络分析的方法,对某体校田径专项的15人小班进行了整体社会网的测量,并描述和分析了班级的情感网络和工作网络。在此基础上,尝试对班级作为初级群体还是社会组织的争论进行分析,并得出了班级更倾向于是社会组织的结论。     

精彩的语文课堂需要好的课堂评价

在语文教学中,我们往往会看到热闹非凡的课堂。然而仔细审视就会发现,课堂中的评价出现了浮夸甚至无效的现象。如何灵活运用语文教学中的评价决定着语文课堂教学的走向,影响着语文教学的效果。真实有效的课堂评价会使学生看清前进的方向,明确学习的目标。同样精当灵动的评价方式也会使我们的语文课堂成为精彩的课堂。采用激励性的评语、教师评价语言灵活多样、课堂评价主体的多元化,教师只有懂得多想得深,才能使语文课堂更精彩。     

美国小班教学综述

阶级阶层利益整合与和谐社会构建——中国农民阶级阶层分化研究

在一个社会里,只要存在阶级,就会存在阶级矛盾,它表现为利益双方的相互对立和依存.利益对立导致双方矛盾不可调和,便发生社会冲突,从而造成巨大的社会动荡;而利益依存凸显了矛盾双方合作的必要,双方可在一定的社会条件下以自己合法的方式获取自己的利益,双方相伴相生,相互依存,这就是阶级整合. 因此,阶级整合的关键就是要找到对立的边线--矛盾双方共同一致的利益,并随双方力量的消长而不断调整政策以适应边线的移动,这个边线就是构建和谐社会的基点.     

代数整数环Z[ω]的素元及剩余类环

作为抽象代数中环理论的两个重要环Z[i]与Z[ω],常以特例的形式散见于抽象代数教材中,对其系统的讨论不多见.而这两个环不仅是抽象代数中的重要实例,而且它们的性质是数论中相关理论的重要基础,特别是在解决费马问题n=3的情形时发挥了关键的作用.文中较为系统的讨论了整环Z[ω],确定了Z[ω]中的素元及其剩余类环所含元素的个数,由此得到数论中一个与Fermat小定理类似的结果.
