面向1:1数字化学习的电子教材设计与开发研究

Research on the Design and Development of Electronic Teaching Materials for 1:1 Digital Learning

随着显示技术、触控技术和虚拟技术等信息技术的快速发展和个人数字终端的广泛普及，数字阅读、数字交流、1:1数字化学习越来越普遍，如何开发面向1:1数字化学习的新型电子教材已受到普遍关注。该研究通过文献法和开发性研究法，基于首要教学理论和多媒体认知理论，构建了面向1:1数字化学习的电子教材设计与开发模式——EDMBFC模式，提出整合21世纪技能的学习目标分析、以完整任务为核心的知识重构、学习路径设计和画面语言的表达是电子教材设计与开发的关键环节，并以小学四年级《科学》电子教材设计与开发实践为例进行了阐释。该模式中目标分析、知识重构、任务序化、学习路径设计等有密切输入输出关系，以这种具有耦合关系的方法为核心构建的EDMBFC开发模式具有较强的操作性，将会提升电子教材开发实践的理性水平。

With the rapid development of display technology， touch technology， virtual technology， information technology and personal digital terminal， digital reading， digital communication and 1:1 digital learning， how to develop e-Book for the 1:1 digital learning has been paid more and more attention. Based on the primary teaching theory and cognitive theory of multimedia， EDMBFC model of designing and developing e-Book is constructed. The method and strategy of analyzing learning goals， reconstructing the knowledge， designing learning path and expressing the visual language are proposed. Science course’s e-Book for the fourth grade is an example to explain EDMBFC model. In the model， there are close relation among the target analysis， knowledge reconfiguration， task ordering and learning path design. The construction method coupled with the EDMBFC as the core development mode has stronger operation. In this way， rational level of developing e-Book will be improved.
