A concept map approach to developing collaborative Mindtools for context‐aware ubiquitous learning     

Gwo‐Jen Hwang  Yen‐Ru Shi  Hui‐Chun Chu 《British journal of educational technology : journal of the Council for Educational Technology》2011,42(5):778-789

Recent advances in mobile and wireless communication technologies have enabled various new learning approaches which situate students in environments that combine real‐world and digital‐world learning resources; moreover, students are allowed to share knowledge or experiences with others during the learning process. Although such an approach seems to be promising and innovative, researchers have indicated several problems when applying it to practical applications, in particular, the lack of proper strategies or tools to assist the students to learn collaboratively in such a learning scenario with abundant content. Students might feel interested when using the mobile devices to learn; however, without proper assistance or guidance, their learning achievements are usually disappointing. To cope with this problem, this study proposes a concept map‐oriented Mindtool for collaborative ubiquitous learning. Experimental results from a natural science course in an elementary school show that this approach not only enhances learning motivation but also improves the learning achievements of the students.  相似文献

Developing a template for National Child Protection Index Reports     

Ager A  Stark L  Chu E  Dewan S  Boothby N 《Child abuse & neglect》2011,35(12):1002-1008

Objectives

What impact does the strengthening of child rights have on the experience and circumstances of children? CRC General Comment 13 emphasizes that defining measurable targets for improvements in child protection is a key element of efforts to strengthen child rights and well-being across the world. This paper describes an attempt to identify key domains relevant to such mapping of child protection indicators, and the feasibility of collecting data—from existing data sources or otherwise—to complete a “National Child Protection Index Report” summarizing achievements and concerns at a national level.

Methods

A process of inter-agency consultation was facilitated by the CPC Learning Network to establish a template for the Index Report. The template was modeled on that used for the “Countdown to 2015” maternal, neonatal and child health initiative, aiming to capture indices not only of key protection risks but also implementation and coverage of key protection measures. The work drew on indicator development and policy initiatives by a number of international child protection agencies. The template developed was used as a basis to pilot national data collection in Indonesia and, at a sub-national level, in northern Uganda.

Findings

The template provides a concise summary of protection issues of relevance to a broad range of constituencies, global and national. However, in the pilot settings, existing routine data collection was inadequate to effectively populate a large proportion of indicators. Mechanisms of collating findings from discrete assessments—another potential source of data for completion of the index report—were also generally underdeveloped.

Practice implications

In settings where state infrastructure allows the collection and analysis of routine data in such domains as health and economic activity, such efforts should be extended to the child protection sector. Discrete assessments by governmental or non-governmental agencies also provide significant potential for more effective sharing and collation of information. National Child Protection sub-clusters or equivalent structures can play an important role in facilitating both of these processes.  相似文献   

当前高校青年教师组织发展对策研究——以河北农业大学理学院为例     

王计军  储秀彦  储彦青 《佳木斯教育学院学报》2011,(5):1-2

高校青年教师是当代高校教师中最有活力、最富有创新精神的群体。他们的思想道德及工作行为更容易影响大学生。他们的价值观、创新精神和敬业精神不仅直接关系到他们自身的发展,更容易影响到大学生的成长与发展。在我院教师队伍中,35岁以下的青年教师占到了55·7%,已经成为教师队伍的主体,因此我们长期以来非常注重对青年教师的培养,一方面注重青年教师业务素质的提高,保证教师质量,另一方面,不断提高青年教师的政治素质,努力打造一支业务素质过硬,政治素质够高的基础课教师队伍,为培养新一代又红又专的社会主义事业建设者打下基础。  相似文献

学习型社会背景下成人终身学习模式探究     

王矗  陈琳 《成人教育》2011,(10):19-22

构建成人终身学习的学习型社会是我国全面建设小康社会的重要目标。学习型社会为成人学习者提供了一个良好的终身学习环境,促进了成人学习不断向全民化、终身化方向发展。通过成人学习者与普通学生不同的心理特征和学习特征的对比分析,结合终身学习的特点提出了成人终身学习的四个模式,即主动式学习模式、发现式学习模式、合作式学习模式、开放式学习模式。最后,在四个模式的基础上进行分析和探讨。  相似文献   

自治与责任:大学组织特色使命的理性反思     

张媛媛  陈大兴 《现代教育论丛》2011,(4)

大学的使命与人们对大学的认知紧密相关,不同的时代,不同的历史时期,有不同的大学认知,也就有不同的大学使命。大学特色使命经历了早期主要以传承与传播知识为己任,到教学与科研并重,再到教学、科研与社会服务并存的三个时期。而现今中国大学组织的特色使命却出现了大学信任度降低、独立性动摇、批判性削弱以及精神灵魂消解等众多问题。这些相关问题都与大学自治性的缺乏密切相关,所以把握好自治与使命的关系对当今我国大学组织的发展具有重要的现实意义。  相似文献   

基于类重叠度欠采样的不平衡模糊多类支持向量机     

吴园园  申立勇 《中国科学院大学学报》2018,35(4):536-543

传统的欠采样方法容易丢失重要的样本信息,且其实验结果的稳定性较差。针对上述问题,提出一种基于类重叠度欠采样的不平衡数据模糊多类支持向量机算法。该算法首先采用LOF局部离群点因子和箱线图的方法清洗训练数据集中的噪声样本,然后根据类重叠度抽取对分类起关键作用的支持向量,并且将代表每个样本点重要程度的类重叠度作为隶属度值,构造模糊多类支持向量机。实验结果表明,该算法克服了随机欠采样的支持向量机容易丢失重要样本信息和实验结果不稳定的缺点,且很好地提升了支持向量机在不平衡且含噪声的数据集上的分类精度,并保持较高的计算效率。  相似文献   

Synchronization control of neutral-type neural networks with sampled-data via adaptive event-triggered communication scheme     

He Zhang  Qian Ma  Junwei Lu  Yuming Chu  Yongmin Li 《Journal of The Franklin Institute》2021,358(3):1999-2014

This paper addresses the problem of synchronization control of neutral-type neural networks with sampled-data, where sampled data will be over a communication network before received by controller. Generally, the communication network is with a bandwidth-limited communication channel. To reduce network burden, an event-triggered scheme is designed between the sampler and communication network. A weak synchronization conditions are derived by using our proposed integral inequality. Finally, a numerical example is given to illustrate the effectiveness and advantage of the proposed results.  相似文献
