远程学习的教学交互模型和教学交互层次塔

A Hierarchical Model for Student and Teacher Interaction in Distance Learning

本研究以Laurillard于2001年提出的学习过程的会话模型为原型,建立了远程学习的教学交互模型。教学交互模型由三个层面所组成:学生与媒体的操作交互、学生与教学要素的信息交互、以及学生的概念和新概念的概念交互。这三个层面的教学交互在学习过程中可能同时发生,学习者的学习在这三个层面的教学交互共同作用下完成。其中信息交互包括三种形式:学生与学习资源的交互、学生与教师的交互、学生与学生的交互。这三种形式的信息交互相互补充。根据远程学习的教学交互模型,作者把学习过程中的三个不同层面的教学交互按照其抽象的程度,从上到下形象地呈现出来,由此形成了教学交互的层次塔。本研究首次将远程学习过程分解为三种教学交互,由此揭示远程学习的教学交互本质。同时,通过采用教学交互层次塔的形式,形象地概括出三个层面教学交互对学习的不同意义及相互依存关系。

Based on the Convers ational Model developed by Laurillard (2001), this paper puts forward a model for s tudent and teacher interaction in dis tance learning. This model cons is ts of three levels: (1) Operational Interaction: the interaction between s tudents and various media; (2) Information Interaction: the interaction between s tudents and the various kinds of information in learning and teaching; and (3) Conceptual Interaction: the interaction between s tudents ' exis ting concepts and new concepts. Thes e three types of interaction may happen at the s ame time in the learning proces s. There exis t three forms of information interaction: between s tudents and learning res ources, s tudents and teachers, and among s tudents thems elves. Thes e three forms complement one another. According to this interaction model, the three levels mentioned above have a hierarchical relations hip and the author believes that this bes t illus trates the nature of dis tance learning and teaching.
