Much online learning nowadays depends upon the creation of a generic, quality online educational experience, with a particular emphasis on collaborative conversations. In this discursive piece, drawing upon published scholarship and our facilitation and evaluation of learning in technology-mediated environments, we propose an enrichment to the pedagogy of such approaches, referred to as learner retreats. Such metaphorical spaces recognise the need for a ‘quiet, safe place’ for the private (internal) reflective thinking of each learner, as a foil to the shared collaborative dialogues in the external world of the online community. This ‘headspace’, with a specific focus on private thinking, is where community learners may probe and enhance current group thinking through reflection and self-regulatory activities. Guidelines are provided for tutors wishing to optimise the use and impact of such personal retreats, promoting deep individual learning and development within the educational experience of online learning communities.  相似文献

随着移动智能设备和移动互联网的出现,移动社交媒介已日益成为人们网络活动和人际交往的新平台。为考察移动社交媒介使用行为、网络自我表露、网络社会支持和友谊质量之间的关系,本研究采用问卷法对473名青少年进行了调查。结果发现:(1)移动社交媒介使用行为会对网络自我表露和网络社会支持产生显著的直接正向影响,网络自我表露会对网络社会支持产生显著的直接正向影响,网络社会支持会对友谊质量产生显著的直接正向影响。(2)移动社交媒介使用行为可以通过网络社会支持的中介作用对友谊质量产生显著的间接影响,还可以通过网络自我表露和网络社会支持的链式中介作用对友谊质量产生显著的间接影响。  相似文献

相关研究表明,由于青少年在网络社交中能够获得他人的认可与支持,网络社交对网络成瘾具有显著的影响。自我价值定向理论认为自我价值是人们行为的终极理由,其中他人的认可与接纳、家庭社会经济地位都是自我价值的重要支撑。当青少年生活在高社会经济地位环境中,其自我价值可能越高,网络社交使用频率对网络成瘾的影响可能会减弱。我们从全国7个省收集了1216份青少年自评的网络社交使用频率、网络成瘾倾向以及父母自评的社会经济地位等指标的数据。结果表明:家庭社会经济地位调节着网络社交使用频率与网络成瘾倾向的关系;进一步的分析表明,在高社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响不显著,而在低社会经济地位的家庭中,青少年的网络社交使用频率对网络成瘾倾向的影响极其显著。结果支持了自我价值定向理论。  相似文献

Objective: Unemployment is a type of chronic stressor that impacts human health. The reasons for how the stress of unemployment affect health is still a matter of discussion. One of the pathways from chronic stress to ill health is mediated by cortisol, and so we set out to compile extant data on how its secretion is affected by unemployment.

Design: A systematic literature search was conducted to establish the cortisol dysregulatory effects of this stressor.

Main outcome measures: Only studies that specifically examined the effects of unemployment on cortisol excretion, and were written in English were included.

Results: Ten reports were obtained and synthesised to determine the severity and complexity of the effect of unemployment on cortisol secretion. The resulting combined evidence is mixed in terms of degree or dynamic of relationship.

Conclusions: The differences between the cumulate findings of the studies can be understood in the context of the lack of both standardised methodology and an absence of consensus on unemployment definition. We propose existing methodologies may be strengthened by acknowledging and accounting for the individual characteristics that may be relevant to the stress experience of unemployment.  相似文献

Currently, fewer older adults are online compared with younger generations. However, with many new initiatives aiming to significantly increase the number of older internet users, they will increasingly be exposed to potential victimisation from internet fraud, a fundamental issue affecting all adult internet users. Despite this, little research has examined online risk‐taking across the adult lifespan or adults' reasoning about risky online behaviors. Using fuzzy trace theory, we investigated adults' online risk‐taking behavior and intentions, and whether these behaviors were related to different ways of reasoning about risk, namely, gist reasoning (using qualitative, intuitive knowledge) and verbatim reasoning (using quantitative, specific knowledge). Participants (326 adults, 18–79 years old, Mage = 49.54 years) reported their past risk‐taking behavior, future online risk intentions, gist and verbatim reasoning about online risk, sensation seeking, and time spent online. Age was negatively correlated with past risk‐taking, time online, future risk intentions, and sensation seeking. However, time spent online was positively related to future risk intentions, suggesting that spending more time using the internet could lead individuals to take more risks. Increased verbatim reasoning predicted increased intentions to take online risks, while gist reasoning predicted reduced intentions to take risks online. Our findings extend online risk research applying fuzzy trace theory to adolescents and young adults and suggest that online safety training incorporating gist‐based reasoning strategies could benefit all adults and, in particular, older generations.

为探讨社交网站使用、线上社会资本、自尊与青少年生活满意度的关系,本研究在社会资本理论及自尊的社会计量器理论的基础上,构建了一个有调节的中介模型。采用社交网站使用强度问卷、线上社会资本问卷、自尊量表以及生活满意度问卷对初(1)到高(3)六个年级的1368名中学生(M=14.63岁,SD=1.75)进行调查研究,结果显示:(1)社交网站使用强度与线上黏接/桥接型社会资本和生活满意度均呈显著正相关;线上黏接型社会资本与自尊、生活满意度均呈显著正相关;线上桥接型社会资本与自尊呈显著正相关,与生活满意度的相关不显著;自尊与生活满意度呈显著正相关。(2)线上黏接型社会资本能够在社交网站使用强度与生活满意度的关系中起部分中介作用。(3)社交网站使用对生活满意度的直接预测作用及线上黏接型社会资本的中介效应会受到自尊的调节,相对于自尊水平低的青少年,社交网站使用更有利于高自尊个体获得线上黏接型社会资本、提升生活满意度。研究结果不仅有利于从社会资本理论及自尊的社会计量器理论视角理解社交网站使用与青少年生活满意度的关系,而且对引导青少年获取社会资本、提升生活满意度具有启示意义。  相似文献

Current definitions of bullying, crafted by policymakers and researchers, raise questions about the ways in which adult constructions of bullying reflect, or fail to reflect, the lived realities of adolescents. In particular, the narrow scope of “bullying,” as currently defined, may over-simplify adolescents’ experiences with relational aggression, which often sit in the space between bullying, discrimination, and harassment. This study investigates adolescents’ talk about bullying on an online message board, as one effort to better understand whether adolescents’ constructions of bullying are aligned with those of researchers and policymakers, and where these youth constructions may overlap with ideas about discrimination and harassment. Conducting a content analysis of data from an online, teen message board, we find that participants frequently use the term bullying to describe adult or familial aggression, and often describe bullying behaviors in ways that reflect elements of discrimination and harassment. We conclude with suggestions for future research and practical approaches that might better bridge gaps between research and practice.  相似文献

Ideas about psychoanalysis via videoconference—videoconference teleanalysis (VT)—are presented with the general understanding that these settings produce a twofold split between various degrees of recognition/negativisation of the absence of the other, on one hand, and the expectation of physical co‐presence, on the other. This split has been put forward as dismantling the here, now, with me pre‐reflexive unity of the analytic experience. This article suggests that both members of the analytic dyad will seek to reappropriate the experience through a forced ego integration that interferes with accessing states of unintegration in the analytic treatment and produces subtle alterations to symbolisation work. The effort to overcome this condition is illustrated with clinical vignettes and therapists’ comments about feelings of inauthenticity and discontent when trying to sustain evenly‐suspended attention, as well as in the perception of a form of flattening of the alive nature of speech. However, this is not a constant for all VT, and mutual understanding can be an important mitigating feature. The focus of the discussion should be on the capacity of the analytic dyad to overcome such a split and not on a direct extrapolation of the perceptual limitations of VT to possible effects on transference / countertransference.  相似文献

People are beginning to develop symbiotic relationships with social networking sites (SNSs), which provide users with abundant opportunities for social interaction. We contend that if people perceive SNSs as sources of social connection, the idea of SNSs may reduce the desire to pursue offline social activities and offline pleasures. Experiment 1 demonstrated that priming with SNSs was associated with a weakened desirability of offline social activities and an increased inclination to work alone. Felt relatedness mediated the link between SNS primes and reduced desire to engage in offline social activities. Experiment 2 showed that exposure to SNS primes reduced the desirability of offline socializing and lowered the desire for offline pleasurable experiences as well. Moreover, heavy users were more susceptible to this detrimental effect. We provide the first experimental evidence that the idea of online social networking may modulate users’ engagement in offline social activities and offline pleasures. Hence, online social networking may satisfy the need for relatedness but undercut the likelihood of reaping enjoyment from offline social life.  相似文献
