智能学习环境中主体需求冲突及其平衡研究

学习环境承载着学习和学习者需求的表达。学习环境的设计需要在终端用户(学生)和社会利益之间、在传统和创新之间不断平衡。当前以传统学校为代表的学习环境设计忽视终端用户和个体用户的主观需求,过于重视社会效益等客观需求。未来教育的实现和发展需要依托创新型学习环境设计的理论与实践进步。基于智能技术支持,以学习环境重构为引领的学校变革是未来学校发展的必然方向。通过在学习环境中融入适切性智能技术能够平衡学习环境中的人类需求冲突。智能学习环境的需求平衡模型是智能学习环境设计的重要组成部分,包含两个部分:(1)智能学习环境需求平衡解析模型——解析智能技术与学习环境内需求冲突之间的主体关系;(2)需求平衡关注度计算模型——计算学习环境的需求平衡程度,以及智能技术干预之后的学习环境的平衡结果。虽然该模型尚属于“概念型公式”,还需要进一步完善,但其提出为智能时代的学习环境设计,以及学习环境中需求冲突的测量和解决提供了理论指导。     

What do we learn from docutainment? Processing hybrid television documentaries

This study examined how hybrid documentary formats, which embed educational contents into narratives, are cognitively processed. Based on existing research and theories, two reception modes were identified: processing with a focus on the narrative plotline and processing with a focus on the thematic structure. In two experiments, two markers of narrative processing could be found for hybrid television documentaries: the experience of transportation and the narrative distance effect. In the first experiment, it could be shown that re-enactments and personal variables enhance the experience of transportation. The second experiment confirmed the narrative distance effect, which occurs independently of reception goals. This means that educational facts which are closely tied to the narrative plotline were learned better than distant facts, regardless of whether the recipients watched the documentary for information or entertainment purposes. The study supplements prior theories on hybrid processing and provides conditions under which narratives are appropriate for learning.

The “Internet of Things”: What It Is and What It Means for Libraries

The “Internet of Things” is a popular buzzword but a poorly understood concept. In short, it refers to everyday objects that can sense the environment around them and communicate that data to other objects and services via the Internet. This column will briefly explain what the Internet of Things is and how it might be useful for libraries. It will also discuss some of the problems with and objections to this technology. A list of currently available Internet of Things examples is also included.     

Charting the Idealism of Intelligent Design: A Small-Scale Map of Local Advocacy

Advocates of intelligent design (ID) promote their movement as a democratic, evidence-based undertaking that opens dialogues about religion and civic affairs. However, with pentadic cartography, this study demonstrates how ID closes the universe of discourse to perspectives other than what Kenneth Burke calls an idealistic orientation. To make this case and to offer counter-statements to ID’s idealism, this study maps discourse generated by an adult Bible study (ABS). Hosted by a Protestant church in America’s northeast, the ABS studied and discussed The Case For A Creator, Lee Strobel’s influential book.

A security-embedded infrastructure for Tele-Traffic Speed Control

In this paper we introduce a novel approach, relying on intelligent engineering, whereby the maximum speed limit at which vehicles on the road can cruise is controlled from some central or distributed facility. The system, as designed, leverages the use of the ubiquitous cellular infrastructure to cut down the costs involved that would otherwise accrue as a result of the need to build a dedicated traffic control system.In the new system maximum speed limits are transmitted from a Central Control Facility (CCF) to all stretches of roads and highways dispersed across urban areas in a highly dynamic manner. The system uses information arriving via a dynamic feedback system on prevailing weather conditions, road conditions, and bulk of traffic, amongst others, before it would broadcast maximum speed limit information to various destinations. When deployed in its final release, this will be done using a highly automated system with little human intervention.The work presented in this paper elaborates the TTC Network Design and RSU Network Distribution for the Tele-Traffic Speed Control System, to remotely manage, enforce, and control the maximum speed limit allowed on road stretches in rural and urban areas for different vehicle categories.The new system has been deployed successfully in a laboratory controlled environment on three vehicle categories; one category representing passenger vehicles, another buses and commuter transport, while the third representing trucks and freight traffic. It is expected that when the system is fully deployed on the wireless infrastructure, speed-related traffic accidents will witness a drop by more than 65-70% according to known accident statistics.
