远程学习工具交互性研究

Interactivity of distance learning tools

技术工具承载着远程教育教学过程,对远程教学交互有着重要支持作用。技术工具的快速发展一方面对远程教学提供了重要支持作用,另一方面也对认识其特性并合理应用提出了挑战。教学交互是远程教育的核心过程。如何认识工具对交互的支持作用,对于远程教育教学的设计与实施至关重要。为了系统分析和评价技术工具的交互特性,本文从技术选择、教学应用和能供性研究3个视角展开文献综述,解析了工具对界面交互、信息交互和概念交互的支持,提出了远程学习工具的交互性分析框架,包括操作可用、联结构建、信息获取、内容加工、交流协作5个维度,共16个指标。本文通过分析框架对远程教学的典型工具,即博客、微博和微信,进行了分析,对比了三种工具的交互性。

Distance instruction is mediated by technology,which plays an important role in instructional interaction.Rapid advances in technology can facilitate distance instruction.Nevertheless,it remains a challenge to make sense of technological affordances and give full play to them.Given that instructional interaction is essential to distance education,it is of paramount importance to investigate how technology enhances interaction,which in turn impacts on the design and implementation of distance instruction.This study set out to conduct a systematic analysis and evaluation of interactivity of distance learning tools,starting with a literature review of technology selection,application and affordances,discussing how technology can enhance interface interaction,informational interaction and conceptual interaction,and developing an analysis framework of distance learning tool interactivity.This 16-index framework is comprised of five dimensions,i.e.ease of operation,connection establishment,information access,content processing,and communication and collaboration.The framework was then used to compare three tools-blog,microblog,and We Chat in terms of their respective interactivity.
