网上语言学习与性别差异

网上语言学习作为一种时新学习趋势正在悄然兴起。在影响语言学习的各种因素中,性别差异毋庸置疑将被给予特别的重视。此研究从生理与认知差异的不同角度,分析了两性差别,并以分析这种差别对于网上语言学习所带来的对学习成果的影响为目的。此研究主要通过问卷调查的形式,样本来自50位大学在校学生和不同背景的社会在职人员。研究的结果表明性别差异的确在网上语言学习的质量方面起着重要的作用,并且对网上语言学习者和基于网上学习的研究者都有着重要的指导作用。　　Keywords:languagelearning;genderdiffer ence;web-basedlearning     

Location preference and flavor aversion reinforced by amphetamine in rats

To associate the identical drug state with both a location and a flavor, rats were given intraperitoneal amphetamine injections and then confined for 20 min in one side of a shuttlebox with access to a flavored solution; on control trials without injections, they were confined for 20 min in the opposite side with a different flavor. In the first experiment, the rats were placed in the shuttlebox immediately after injections; in the second experiment, they were placed in the shuttlebox 20 min after injections. Subsequent free-choice tests in both experiments revealed an increased choice of the side of the shuttlebox associated with amphetamine but also an aversion to the flavored solution associated with the drug.     

Problematising the ‘Career Academic’ in UK construction and engineering education: does the system want what the system gets?

‘Career Academics’ are principally research-led, entering academia with limited or no industrial or practical experience. UK Higher Education Institutions welcome them for their potential to attain research grant funding and publish world-leading journal papers, ultimately enhancing institutional reputation. This polemical paper problematises the Career Academic around three areas: their institutional appeal; their impact on the student experience, team dynamics and broader academic functions; and current strategic policy to employ them. We also argue that recent UK Government teaching-focused initiatives will not address needs to employ practical academics, or ‘Pracademics’ in predominantly vocational Construction and Engineering Education. We generate questions for policy-makers, institutions and those implementing strategy. We argue that research is key, but partial rebalancing will achieve a diverse academic skill base to achieve contextualised construction and engineering education. In wider European contexts, the paper resonates with issues of academic ‘drift’ and provides reflection for others on the UK context.     

The Development of Memory and Processing Capacity

The assumption of some developmental theories that short-term memory is the workspace of higher cognitive processes, and consequently that span measures processing capacity, is claimed to be inconsistent with the working memory literature. 4 experiments, using children aged 5 to 12 years, contrast this theory with a model in which short-term memory and the processing space component of working memory are at least partly distinct. Experiments 1 and 2 varied processing load, holding duration constant. The processing load manipulation had little effect on recall of a short-term memory preload. Experiments 3 and 4 failed to support the prediction that the greater processing efficiency of older children would be associated with slower loss of information from short-term memory. Although counting and rehearsal rates increased with age, and correlated with span, they did not predict the rate of loss of memory preload due to intervening counting. The data suggest that effects obtained with short-term memory span do not provide clear indications of overall working memory development, because short-term memory span and the processing space component of working memory entail distinct systems.     

Metaphors as expressions of followers’ experiences with academic leadership

Researchers continue to investigate and understand leadership in higher education. However, leadership does not stand alone; it is part of an interactive dyad with followers. Building on a previous study that aimed to unpack academics’ experiences of leadership in higher education with a view to enhancing leadership practices, this paper creatively examines metaphors in order to understand how followers interpret academic leadership, followership and follower–leader interactions. Data were gathered from academics in follower roles through written narratives or face-to-face interviews in accordance with participants’ preferences. Drawing on a social constructionist perspective and a metaphorical conceptual framework, we align with Lakoff and Johnson [1980. Metaphors we live by. Chicago: University of Chicago Press] who claim that metaphors pervade thought and action. Our findings illuminate followers’ understandings of leadership efficacy; their multifaceted responses to particular encounters with leaders and the complexities of following and leading in university workplaces. We demonstrate how metaphors can explain some of the concerns and constraints shaping follower and leader interactions in academia. Our analysis highlights the importance of framing leadership as a relational and dynamic construct.     

Research leadership in writing for publication: A theoretical framework

Academics experience difficulty in managing competing tasks, particularly in relation to writing for publication. In a study conducted on a writing retreat, analysis of data obtained from academic writers revealed that facilitative leadership provided at a writing retreat was central to managing task complexity and writing‐related anxiety. The question remains, however, about how this leadership can be modelled in campus settings in order to continue to support academics in managing the complexity of their multiple roles as teachers, researchers and writers, beyond purely technical‐rational approaches. This article outlines one approach to answering this question: it explains how containment theory was used to shed light on the leadership role at the writing retreat, and it proposes a model—strategic engagement—for the leadership role in writing for publication in campus settings.     

Is adaptation to task complexity really beneficial for performance?

Theories of self-regulated learning assume that learners flexibly adapt their learning process to external task demands and that this is positively related to performance. In this study, university students (n = 119) solved three tasks that greatly differed in complexity. Their learning processes were captured in detail by task-specific questionnaires and computer-generated log files. Results indicate that students adapted almost all learning processes significantly to task complexity. For example, students accessed more hypertext pages for complex tasks than for simple tasks. However, this kind of adaptation was not consistently related to performance. For variables capturing learners’ self-regulation, such as the number of accessed hypertext pages, more pronounced adaptation was significantly and positively related to performance even when learners’ general processing depth was statistically controlled. Results were less consistent for variables capturing learners’ self-monitoring, such as their judged task complexity.
