Epistemic beliefs in action: Spontaneous reflections about knowledge and knowing during online information searching and their influence on learning

In the present study it was investigated whether high school students are spontaneously able to reflect epistemologically during online searching for information about a controversial topic. In addition, we examined whether activating epistemic beliefs is related to individual characteristics, such as prior knowledge of the topic and argumentative reasoning skill; also whether learning from the Web is influenced by epistemic beliefs in action and the ability to detect fallacies in arguments. The participants (N = 64) were students of Grade 13, who were asked to think aloud during navigation. Qualitative and quantitative analyses were performed. Findings reveal that most participants spontaneously activated beliefs about all four dimensions identified in the literature, that is, about the simplicity/complexity, certainty/uncertainty, justification, and source of knowledge, at different levels of sophistication. Most epistemic reflections were about the source of knowledge. Two patterns of contextualized epistemic beliefs emerged and significantly influenced learning from the Web, which was also affected by participants' ability to identify argumentative fallacies.     

The disaster of the ‘self‐managing school’ – genesis,trajectory, undisclosed agenda,and effects

Sometimes an educational idea is inexplicably adopted around the world with remarkable speed and consistency and in the absence of a proper evidence base or with little regard or respect for teachers, students or learning. This paper examines what has arguably been the most contentious and virulent educational reform of the past half‐century. Variously labelled, in what amounts to the self‐managing school, what this reform has done is virtually dismantle public education and privatise it without public debate or proper scrutiny. This paper considers the alleged claims by the enthusiastic proponents and examines what has subsequently transpired, particularly in respect of the most disadvantaged students and the broader mission of improved learning.     

The effect of context on student engagement in engineering

The self-belief, motivation, tendency to procrastinate and learning styles of engineering students are discussed. It is proposed that engineering has developed an idiom and a learning approach that favours the dominant client, i.e. men, while simultaneously undermining the self-efficacy and motivation of women. Thematic coherence and teaching within a context that is familiar to students have been shown previously to be effective approaches for engaging students and are extended here to utilise the common experiences of all students to initiate the learning cycle. These approaches are combined with a template for teaching that uses the 5Es (Engage, Explore, Explain, Elaborate and Evaluate) in order to render the fundamentals of engineering more accessible to all students. This methodology can be introduced by individual instructors, who will be rewarded by students who are more engaged, more motivated and more likely to give a higher rating to the instructor and the course.     

中部高校海外人才引进工作思考

中部崛起,关键靠人才。当前,人才流失、引进难度大已成为制约中部高校发展的瓶颈。随着新一轮海归潮的来临,中部高校必须解放思想,采取超常规的举措,建立一套科学、完善的引进人才政策体系和考评机制,增强服务意识,努力确保海外人才引得来、用得好、留得住,发挥最大效益。     

网络远程教育的个体生态学研究

从个体生态学视角可以深入研究网络远程教育中生态主体与生态环境间的相互关系。本文以国家远程教育生态系统中的生态主体和生态环境为对象,研究了生态主体与生态环境间的作用机制和作用原理．利用个体生态学的生态适应原理分析了生态主体对生态环境的适应策略,利用花盆效应理论分析了网络远程教育试点中生态主体与生态环境的不协调现象。本研究对于教育行政部门、远程教育院校和校外学习中心如何适应和改造生态环境具有一定的指导意义。     

在线学习活动设计与网络教学平台的功能

在线实践社区中教师同伴互助活动的可视化

教师同伴互助活动的可视化有助于设计者对在线实践社区功能的反思和更精致设计的决策,对于参与在线实践社区同伴互助活动的教师而言,有利于识别教师同伴互助的行为模式、增加社区感、增强社会存在感、吸引教师的专注力和个人行为的反思与行动。对于研究的本身,为进一步的教师同伴互助行为的预测和挖掘奠定了基础。本文的目标是探究教师同伴互助活动可视化的思路、技术和方法。     

基于“健康中国2030”视角下的福建省城市社区老年人体育活动现状*

基于“健康中国2030”规划纲要视角分析福建省城市社区老年人体育活动现状,采用问卷调查法、访谈法、文献法、数理统计法,分别抽取福州、厦门、莆田、泉州、南平、三明6个地市的部分社区老年人群进行调研。结果显示（1）所调查老年人患慢性疾病率高达58.76%;（2）老年人参与健身意识较强;（3）老年人参与体育健身积极性高;（4）老年人对体育健身知识缺乏了解。结论：福建省城市社区专业健身指导员短缺、老年人对体育健身知识了解匮乏、锻炼场地设施有限、家人支持老年人参加体育健身,但陪伴不足等是影响福建省城市社区老年人参与体育健身的主要因素。     

贵阳饮用水源地土地覆被（LandCover）格局分析

在遥感与地理信息系统的支持下,从2004年的中巴资源卫星影像中提取贵阳水源地三大水库水源涵养地作为研究区域,采用景观指数法进行水源地土地覆被格局现状研究。结果表明：以三大水库为中心的水源涵养地总面积为127584．63hm;旱地、水田和建设用地三种受人类生产活动影响严重的用地类型占研究总面积的59．91％,而林地和灌草地占33．71％,若单独考虑林地,则仅占总面积的22．60％,斑块大小上仅具有相对较大的,平均斑块面积为4．49hm;旱地具有最高优势度,是人类生产活动导致大斑块耕作所致;综上所述,林地保护和质量提升具有一定难度;灌草地破碎化严重,斑块数量多,平均斑块面积不大,可以考虑对灌草地的林地化改造,部分实现原有林地的连接,扩大林地面积。
