从多态表征到置身参与:虚拟现实技术助力学科教学的价值路径

虚拟现实技术作为一种沉浸式交互虚拟系统,其教育功用应有效辐射学科教学,助力学科知识获得与学科思维培养。针对当前学科教学过程中“抽象符号→技能训练→工具思维”的现实问题,探析了虚拟现实技术在学科教学过程中的直观学习资源、知识有效应用与培养学科思维等价值;接着提出了虚拟现实助力学科教学的四种类型:独立式学科本位型、分布式学科本位型、独立式项目融合型与分布式项目融合型。最后依据虚拟现实学科教学价值与虚拟现实学科教学类型提出了虚拟现实助力学科教学的实践路径:直观资源的操作体验,指向知识内容有效获得;模拟情境的知识应用,促进知识向能力的转化;真实场景的问题解决,实现知识向思维的通达。以优化学科教学过程,为虚拟现实技术应用于教与学过程提供参考。     

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.     

Research results of two personal learning environments experiments in a higher education institution

This paper focuses on institutionally powered personal learning environments (iPLEs). The concept of the iPLE can be seen as a way universities can incorporate learner-centred approach into the architecture of their technology-enhanced learning environments. The aim of this paper is to pose that there are other ways to learn complementary to virtual learning environments, such as using distributed Web 2.0 tools from personal learning environments (PLEs). With that aim in mind, this paper presents an exploratory study with two different iPLE configurations, analyses how they modify the learning–teaching process, and reports their perceived usefulness from the students' point of view. These two case studies were carried out by a research group of educational technology from a Spanish university in graduate and postgraduate courses. As reported by other case studies, the results revealed that students use the environment basically in the academic context and this usage is conceived as another time and effort requiring task. This fact can be observed in the low level iPLEs customization. The overall conclusions we can extract are, on the one hand, that the new environment to integrate informal and formal learning should be flexible and adaptable to the student's needs and preferences and, on the other hand, that academic tools might someday become personal tools.
