An evolving Learning Management System for new educational environments using 2.0 tools

The tools used in learning processes are in a continuous state of flux. One of the most significant changes is the application of Information and Communications technologies (ICTs) to educational contexts. This provides new possible ways to carry out learning activities, new learning services, the possibility to use new kinds of contents and activities, etc. However, ICTs have not provided as many advantages as they were supposed to, so changes are necessary. In this context, a new set of tools, Web 2.0, offers a new way to understand the Web, in which the user is the centre. Further, users can cooperate in order to define contents. This concept is also applied in technology-mediated learning but there are important problems when one tries to integrate such tools and concepts with existing systems. This paper explores the integration of these tools in traditional learning environments, the various possibilities and their advantages and drawbacks. After that, an interoperability scenario is described and two experiences are presented to show how 2.0 tools can be integrated in learning activities, and its effect in educational process.     

ICT tools in environmental education: reviewing two newcomers to schools

United Nations of Education Scientific and Cultural Organisation’s (UNESCO’s) founding statements about environmental education (EE) in the 1970s positioned it as a multidisciplinary field of inquiry. When enacted as such, it challenges traditional ways of organising secondary school education by academic subject areas. Equally, according to UNESCO, EE requires various forms of integrated and project-based teaching and learning approaches. These can involve hands-on experimentation alongside the retrieval and critical analysis of information from diverse sources and perspectives, and with different qualities and statuses. Multidisciplinary and knowledge engagement challenges are key considerations for an EE curriculum designed to harness information and communication technologies (ICT) to support and enhance student learning, which also challenge traditional instructional priorities that for example are largely based on textbooks. This review summarises research that has sought to integrate ICT and digital tools in EE. A key finding is that while there is a rich variety of such tools and applications available, there is far less research on their fit with and implications for student learning. The review calls for further studies that will provide models of productive forms of teaching and learning that harness ICT resources, particularly in developing the goals and methodologies of EE in the twenty-first century.     

货币政策框架由数量型调控向价格型调控转变研究

随着社会主义市场经济体制的不断完善和利率市场化改革的稳步推进,金融宏观调控从偏重运用数量型工具向更多运用价格型工具转变。借助货币政策规则理论和计量经济方法,对现阶段我国货币政策框架由数量型调控向价格型调控转变的可行性及路径做一系统分析。得出:价格型货币政策工具的调控绩效总体上要优于数量性货币政策工具;实现数量型调控向价格型调控转变,应进一步增强货币政策独立性和透明度,加快金融市场发展,推进利率市场化及人民币汇率生成机制改革。     

数控机床切削控制能力对机械加工精确度影响

在数控技术运用中,通过振动控制与速度控制等,在提高数控机床加工精确度的同时,也可提高加工的质量和经济效益。数控机床的智能化,运用计算机建模软件加强对机械加工的程序控制,在加强切削等环节控制能力的同时,追求高精确度的实现。机械加工精确度既体现数控机床的技术含量,也体现操作控制者技术技能水平,其与企业的发展有着直接的关系。     

中英文网络检索工具评价与比较

选用AltaVista 和搜狐两个网络检索工具, 利用10 个来自实际参考咨询的检索提问分别进行检索测试, 并根据由索引数据库构成、检索功能、检索效果、检索结果显示、用户负担五方面构成的评价标准, 进行具体评述和比较。由于无法估算网络中相关信息的总量, 所以文中忽略了查全率R 的计算, 但根据需要采用了重复率R r、死链接率Rd 两个新指标作为检索效果评价的标准。在上述评价的基础上, 分析中文检索工具存在的差距, 以及在选择评价标准时, 根据中、英文检索工具的特点, 应该有哪些不同。

An empirical investigation of factors influencing the adoption of data mining tools

Previous studies explored the adoption of various information technologies. However, there is little empirical research on factors influencing the adoption of data mining tools (DMTs), particularly at an individual level. This study investigates how users perceive and adopt DMTs to broaden practical knowledge for the business intelligence community. First, this study develops a theoretical model based on the Technology Acceptance Model 3, and then examines its perceived usefulness, perceived ease of use, and its ability to explain users’ intentions to use DMTs. The model's determinants include 4 categories: the task-oriented dimension (job relevance, output quality, result demonstrability, response time, and format), control beliefs (computer self-efficacy and perceptions of external control), emotion (computer anxiety), and intrinsic motivation (computer playfulness). This study also surveys the moderating effect of experience and output quality on the determinants of DMT adoption and use. An empirical study involving 206 DMT users was conducted to evaluate the model using structural equation modeling. Results demonstrate that the proposed model explains 58% of the variance. The findings of this study have interesting implications with respect to DMT adoption, both for researchers and practitioners.
