A collaborative assessment of students’ placement learning

The research informing this paper set out to investigate the qualitative experiences of students, supervisors and tutors involved in a summative collaborative assessment of placement learning on an undergraduate professional qualifying programme in the UK. Analysis of data gathered through semi-structured interviews provides valuable insights into its use. In particular, engagement in a collaborative assessment brings a degree of exposure for all concerned. Participants need to feel ‘able’ to participate, and ability to participate is linked to notions of agency and autonomy. Collaborative assessment design needs to acknowledge power relations and include strategies to reduce imbalances. The importance of recognising and working with the complexities of assessment should not be underestimated. Criterion referencing offers a guide to support consistency but can also falsely present assessment as mechanistic and instrumental. The research shows that it is in the ‘doing’ of assessment that a ‘shared language’ is developed. It demonstrates the value of active student engagement in assessment in relation to the construction and use of theory, developing reflective practice and assessment literacy. The collaborative assessment provides students with the opportunity to experience a ‘performance of understanding’ in a community of practice that, whilst pressured, reflects ‘real’ professional life.     

女博士就业初探——基于落实率和求职过程及结果的分析

本文通过对北京某综合性研究型大学2005年-2010年博士毕业生历史数据的梳理,以及对2010届毕业生的问卷调查,比较了男、女博士毕业生的年终落实率和求职过程与结果。研究发现,女博士获得第一个工作机会所需时间长于男博士。但在落实率、获得的工作机会总数、实习期间和实习期后起薪,以及工作满意度方面,均不存在显著的性别差异。基于上述结果,本文讨论了女博士在求职过程和结果上的特殊性,提出了有针对性的辅导建议。

文本聚类分析结果可视化方法研究

针对文本聚类分析结果表达中缺乏语义关系的缺陷,本文利用人们在可视化形式下对模型和结构的理解和获取能力,提出了一种新的可视化表达方法。通过改进的Force-directed模型对聚类分析结果进行文本布局,表现文本间的语义相似关系;使用等值线生成算法构建层次性主题图,聚集和提炼文本主题;最终实现文本聚类分析结果的语义直观表达。实验结果表明,这种可视化方法不仅能够有效地表达聚类结果,体现类间、文本间的语义相关程度,而且还有助于发现隐含的信息,并通过类别之间的关联实现有效的信息导航。     

Learning in the practicum: engaging pre-service teachers in reflective practice in the online space

It is argued that online discussion is a useful tool for creating opportunities for learning in teacher education. In a project designed to improve the practicum in rural areas, researchers placed pre-service teachers (PSTs) in two different moderated online discussion forums: an unstructured personal blog space and a structured threaded discussion forum where discussion topics guided them to reflect on their practicum experiences in relation to theoretical components of their studies. Findings indicated a marked difference in the contributions made to each form of online discussion with significantly greater participation in the unstructured blog format. Using Kreber and Cranton’s hierarchy of reflection, analyses of both forums found that PSTs rarely engaged in high-level reflection. Examination of lecturer involvement in the forums suggests that their contributions did not sufficiently encourage PSTs towards optimum critical reflection. These results leave the researchers considering ways in which the practicum experience can better promote reflective practice in this crucial, component of teacher education.     

基于NSGA-Ⅱ的给水管网传感器多目标优化选址研究

在EPANET2污染物侵入模拟的基础上,以污染事件期望监测时间最短和传感器系统能够监测到的污染事件比例最大为优化目标,研究了传感器选址的多目标优化问题。针对选址问题的特性。通过改进非支配排序遗传算法-Ⅱ（NSGA-Ⅱ）的编码方式、交叉算子和变异算子,使其能够较好地解决给水管网传感器多目标优化选址问题。结合一管网算例,利用改进过的NSGA-Ⅱ给出了一组Pareto解．并对两个极端解对应的选址结果进行了权衡分析。提出的优化模型与求解方法对给水管网传感器多目标选址具有一定的参考作用。     

The student experience of piloting multi-modal performance feedback tools in health and social care practice (work)-based settings

The aim of this study was to evaluate newly developed performance feedback tools from the student perspective. The tools were innovative in both their mode of delivery and the range of stakeholders they involved in the feedback process. By using the tools in health and social care settings, students were able to engage in interprofessional assessment of common competences and obtain performance feedback from a range of stakeholders not commonly involved in work-based learning; these included peers and service users. This paper discusses the ways in which the performance feedback tools were developed by a collaborative programme and compares their delivery, across a wide range of professions and work-based settings, in paper-based, web-based and mobile formats. The tools were evaluated through a series of profession-specific focus groups involving 85 students and 7 professions. The data were analysed thematically and reduced to three key categories: mode of delivery, assessment tool dynamics and work-based issues. These will be discussed in detail. The students agreed that the structured way of capturing and documenting feedback from several sources would support their practice placement learning. The reflective nature of the tools and the capacity for guiding reflection was also welcomed. The concepts of gaining service user, peer and/or interprofessional feedback on performance were new to some professions and evoked questions of reliability and validity, alongside appreciation of the value they added to the assessment process.     

电影植入式广告：商业与艺术相生不相克

随着电影产业的不断发展壮大,电影功能也不断从娱乐、教育到文化传播等方面扩展延伸。“电影既有娱乐教育的功能,又肩负着一定的教育感化责任”。在商业高度发达的今天,电影又在不知不觉中变成了传播广告的载体。一时间,业界哗然,支持者与反对者各持己见。而近期上映的《变形金刚Ⅱ》再次将植入式广告的讨论推到了风口浪尖。那么,电影的商业性与艺术性是否完全对立？两者能否在某种程度上实现统一。从而达到共赢呢？拟就这一问题进行论述。
