社会化问答社区的出现改变了原有的问答模式并拓展了知识获取的途径。回答者作为知识的主要贡献者,是促进问答社区内知识传递的核心要素。现有关于问答社区用户的研究普遍以用户的属性数据为依据,较少考虑使用个体连接所形成的关系数据进行分析。本文以中文问答社区"知乎"为研究对象,爬取了"流行音乐"和"英语学习"两个话题下的大规模数据,通过构建回答者关注关系网络,定义和量化直接连接和间接连接两类同伴关系,使用网络自回归模型探究同伴效应对知识贡献行为的影响。研究发现,回答者的知识贡献行为会受到直接和间接连接同伴效应的正向影响,但是间接连接同伴效应会随着回答者网络密度的增加而逐渐减弱甚至消失,聚类系数对回答者的知识贡献行为有负向影响。 相似文献

AbstractPositive student attitude towards peer assessment can be demonstrated through high-quality peer assessment activities. Research findings on students’ attitudes before and after such activities were mixed. This study was conducted using a mixed-methods approach to investigate the underlying factors influencing students’ attitude change. Participants were students enrolled in an online graduate-level assessment course in the college of education in a university in the southeast United States in the fall of 2017 (N?=?31). Surveys and interviews were used to collect quantitative and qualitative data separately, both of which indicated that perceived accurate and specific feedback tended to help students shift to more positive attitudes towards online peer assessment. In addition, final task score improvement after the activity was correlated with positive attitude change. Qualitative results also identified other factors, such as communication with the peers’ work and logistic concerns. The current study offers insights for researchers and instructors to promote positive attitude changes in online peer assessment activities. 相似文献

高职院校中学生的年龄大体相当,而对于部分学生来说教师的说教式教导很容引起学生的反感,实践证明在高职院校中进行学生党支部朋辈帮扶活动相较于教师的指导在一程度上更有效果.但是部分高职院校由于缺乏经验,在制度和方法上的缺陷导致高职学生党支部朋辈帮扶活动开展的不尽如人意.为了解决这个问题,本文在对高职学生党支部朋辈帮扶活动实施现状进行分析的基础上,探讨了高职学生党支部朋辈帮扶活动开展的意义,重点研究了高职学生党支部朋辈帮扶的策略. 相似文献

为探究父母消极控制与反馈、黑暗人格、同伴关系、社会适应的关系以及其内部作用机制,对1934名中学生采用整群施测法进行问卷调查。结果发现:1.父母消极控制与反馈、黑暗人格和积极社会适应呈显著负相关,和消极社会适应呈显著正相关;同伴关系和积极社会适应呈显著正相关,和消极社会适应呈显著负相关。2.控制了家庭社会经济地位的影响后,黑暗人格、同伴关系在父母消极控制与反馈对社会适应的影响中起链式中介作用。该研究验证和拓展了家庭社会化和社会学习等理论在青少年社会适应影响机制中的应用。 相似文献

In recent years, most studies on flipped classrooms or flipped learning have focused on learners’ motivation, academic achievement and teachers’ and students’ perceptions of the flipped classroom. Little research has involved interactions in the flipped classroom. This study aims to show that in-class collaborative learning in the flipped classroom can not only be conceived as a collective activity consisting of discrete actions, but also as a systematic activity. From the activity-theoretical perspective, contradictions were found between components of an activity such as subject, tools, rules, community, division of labor, object and outcome. This study conducted a pre-experiment, selecting one lesson of the seventh-grade Information Technology Course as the learning content, conducted in a flipped classroom. Three triads with different compositions were specifically observed by recording their interactions. More second-level contradictions existed between subject and tools, and division of labor within the low-level triad than within the other two triads, and more first-level contradictions also occurred within the low-level triad than within the other two triads. Most second-level contradictions within the high-level triad were resolved by self-regulation of cognition. Instead, most second-level contradictions within the mixed-level triad were overcome by co-regulation or shared regulation of cognition. This study sheds light on how to effectively design and implement flipped learning, and provides a new approach for analyzing interactions in the classroom. 相似文献

Feedback has been increasingly conceptualised as a dialogical process where students interpret the provided information through interaction with comment providers and use it to enhance their learning. A major challenge for the development of sustainable feedback is closely related to how students think about it. This study explored how 25 Chinese university students made sense of instructor and peer feedback following their English group presentations. The findings reveal that most of the participants perceived more judging and encouraging functions of feedback than its improving functions, which reflected their conventional thinking about feedback. Variation also existed in the perceived functions of instructor and peer feedback. Imbalanced power relations, face, group harmony and instructors’ feedback practice as well as students’ past learning and assessment experiences appeared to inhibit the participants from viewing feedback in a sustainable way. This study sheds light on college students’ complex thinking about feedback in a non-Anglophone context which has been neglected in the feedback literature, and has implications for educators and researchers in facilitating sustainable feedback in the Chinese context and the non-Chinese contexts where Chinese students study. 相似文献

AbstractPeer assessment has proven to have positive learning outcomes. Importantly, peer assessment is a social process and some claim that the use of anonymity might have advantages. However, the findings have not always been in the same direction. Our aims were: (a) to review the effects of using anonymity in peer assessment on performance, peer feedback content, peer grading accuracy, social effects and students’ perspective on peer assessment; and (b) to investigate the effects of four moderating variables (educational level, peer grading, assessment aids, direction of anonymity) in relation to anonymity. A literature search was conducted including five different terms related to peer assessment (e.g., peer feedback) and anonymity. Fourteen studies that used a control group or a within group design were found. The narrative review revealed that anonymous peer assessment seems to provide advantages for students’ perceptions about the learning value of peer assessment, delivering more critical peer feedback, increased self-perceived social effects, a slight tendency for more performance, especially in higher education and with less peer assessment aids. Some conclusions are that: (a) when implementing anonymity in peer assessment the instructional context and goals need to be considered, (b) existent empirical research is still limited, and (c) future research should employ stronger and more complex research designs. 相似文献
