合作学习研究的综述

合作学习(cooperative learning)是目前世界上许多国家都普遍采用的一种富有创意和实效的教学理论与策略体系。文章主要阐述了合作学习的概念、类型、方法,及理论。最后,指出我国合作学习研究出现的问题和未来展望。文章认为强化实验研究、探讨与课堂教学相结合的研究,及重视教师在合作学习的作用是今后该领域发展的主要方向。     

Cognition-based and affect-based trust as mediators of leader behavior influences on team performance

We develop a model in which cognitive and affective trust in the leader mediate the relationship between leader behavior and team psychological states that, in turn, drive team performance. The model is tested on a sample of 191 financial services teams in Hong Kong and the U.S. Servant leadership influenced team performance through affect-based trust and team psychological safety. Transformational leadership influenced team performance indirectly through cognition-based trust. Cognition-based trust directly influenced team potency and indirectly (through affect-based trust) influenced team psychological safety. The effects of leader behavior on team performance were fully mediated through the trust in leader variables and the team psychological states. Servant leadership explained an additional 10% of the variance in team performance beyond the effect of transformational leadership. We discuss implications of these results for research on the relationship between leader behavior and team performance, and for efforts to enhance leader development by combining knowledge from different leadership theories.     

Influences of head and torso movement before and during affordance perception

Previous research has shown that body sway (both standing and seated) is related to the accuracy of affordance judgments. The authors investigated the influence of seated head and torso movement on the perception of a novel affordance for wheelchair locomotion. Healthy adults without prior wheelchair experience judged the lowest lintel under which they could roll in the wheelchair. Prior to judgments, participants were given brief (≈ 2 min) practice at self-controlled wheelchair locomotion. During practice, the participant's head either was or was not restrained within the wheelchair. During the subsequent judgment session, the participant's head was or was not restrained. The accuracy of affordance judgments was influenced by restraint during the practice session and also by restraint during the judgment session. The authors collected data on head movement during the judgment session (when participants were not restrained). These data revealed that movement during judgment sessions was influenced by whether or not participants were restrained during the practice session. Overall, the results reveal that the availability of head movements (i.e., being unrestrained) and the nature of head movements (during unrestrained judgment sessions) were causally related to the accuracy of affordance judgments.     

Stability of peer victimization in early adolescence: effects of timing and duration

The current study investigated the stability of peer victimization and the impact of the timing and duration of victimization on psychological and academic outcomes for boys and girls on a sample of 863 middle school students. Results demonstrated strong support for the onset hypothesis and concurrent effects of maladjustment in anxiety, depression, self-esteem, poor school attitude, GPA, and attendance. Support for the cessation hypothesis was mixed, depending on the outcome and gender: boys demonstrated recovery from internalizing distress, whereas girls demonstrated residual effects, even after the cessation of victimization. Girls also demonstrated residual effects of victimization on grades, and both boys and girls evidenced residual effects of victimization on attendance. Regarding duration of victimization, there was strong support for the life-events model of stress and coping across almost all outcomes, suggesting that even temporary experiences of victimization could have a negative impact on psychological and academic outcomes. Overall, results demonstrated the importance of considering the timing and duration of victimization in understanding the risks and damaging effects of victimization. The results from this study also highlight both the need and the potential to intervene during early adolescence when peer relationships are taking on increasing importance, as well as the importance of helping students regain social-emotional and academic functioning, even after victimization ceases.     

互联网与中国公民社会研究:反思与展望

自20世纪90年代初以来,中国公民社会研究日益成为热门领域。时至今日,尽管对于公民(市民)社会这一源于西方的术语是否适用中国还有争论,但学术界的研究文献早已汗牛充栋,公民社会一词也在大众传媒上频频出现。在讨论中国公民社会的发展前景时,制度环境多被认为是最主要的制约因素;也正因为如此,海外论者多用新生的(nascent)或初期的(incipient)来形容中国公民社会,有的甚至从根本上否认中国公民社会的存在及成长的可能性。当制度环境在短期内难以根本转变的情况下,中国公民社会发展之路何在?这无疑成为一个现实问题。     

壮族巫术、巫师与巫医

壮族医学和壮族的巫术、巫师、巫医之间的关系是十分密切的。最初壮族医学起源于壮族巫术,最早的壮族巫医则产生于壮族巫师之中,并由巫医发展为民间医生。后来,随着科学文化的发展,壮族医学才从巫术中独立出来,成为一门专门的学科。壮族巫术、巫师与巫医的产生和发展,是壮族医学产生和发展过程中一个不可跨越和替代的历史阶段。     

重拾被遗忘的东方——兼评“东方哲学”与五卷本《东方哲学史》

在当代中国哲学界,东方哲学几乎属于被遗忘的领域:它从学科上被取消,从知识结构上被排除,从价值上被看轻,导致中国哲学界陷入一种中、西二元分立的简约化的格局之中。由中国社会科学院哲学研究所东方哲学研究室组织编写的五卷本《东方哲学史》的问世,对于改变这一状况起到了积极的作用。但是,东方哲学概念该如何理解?相较于西方民族,东方民族有着怎样的思考     

Women with Childhood ADHD: Comparisons by Diagnostic Group and Gender

This study compared adult women with childhood ADHD to adult women without childhood ADHD and to adult men with childhood ADHD. The participants, all from a larger longitudinal study, included 30 women and 30 men (approximately age 23 to 24) with childhood ADHD, and 27 women without ADHD. Women with childhood ADHD were matched to comparison women on age, ethnicity, and parental education, and to men with childhood ADHD on age, ethnicity, and IQ. Self- and parent-reports of internalizing, interpersonal, academic, and job impairment, as well as substance use and delinquency indicated group differences on measures of self-esteem, interpersonal and vocational functioning, as well as substance use. Follow-up planned comparison tests revealed that almost all of these differences emerged by diagnostic status, and not by gender. This study adds to research on the negative adult outcomes of ADHD and demonstrates that the outcomes of men and women with childhood ADHD are relatively similar.     

Linking ethical leadership to employee performance: The roles of leader–member exchange,self-efficacy,and organizational identification

This research investigated the link between ethical leadership and performance using data from the People’s Republic of China. Consistent with social exchange, social learning, and social identity theories, we examined leader–member exchange (LMX), self-efficacy, and organizational identification as mediators of the ethical leadership to performance relationship. Results from 72 supervisors and 201 immediate direct reports revealed that ethical leadership was positively and significantly related to employee performance as rated by their immediate supervisors and that this relationship was fully mediated by LMX, self-efficacy, and organizational identification, controlling for procedural fairness. We discuss implications of our findings for theory and practice.     

I am against us? Unpacking cultural differences in ingroup favoritism via dialecticism

The authors proposed a novel explanation for cultural differences in ingroup favoritism (dialecticism) and tested this hypothesis across cultures/ethnicities, domains, and levels of analysis (explicit vs. implicit, cognitive vs. affective). Dialecticism refers to the cognitive tendency to tolerate contradiction and is more frequently found among East Asian than North American cultures. In Study 1, Chinese were significantly less positive, compared to European Americans, in their explicit judgments of family members. Study 2 investigated ingroup attitudes among Chinese, Latinos, and European Americans. Only Chinese participants showed significant in-group derogation, relative to the other groups, and dialecticism (Dialectical Self Scale) was associated with participants' in group attitudes. Study 3 manipulated dialectical versus linear lay beliefs; participants primed with dialecticism showed more negative, explicit ingroup attitudes. Although ingroup disfavoring tendencies were more prevalent among Chinese across studies, they may be a reflection of one's culturally based lay beliefs rather than deep-rooted negative feelings toward one's ingroup.
