多媒体学习的认知—传播模型及其基本特征

Cognition-propagation Model and Basic Characteristics of Multimedia Learning

在多媒体学习过程中,交互行为参与的频率已经越来越高,它深刻地改变了多媒体学习活动的本质与形态,"三通道"多媒体学习的认知—传播模型更全面有效地刻画了多媒体学习的过程与本质。多媒体学习认知—传播模型依据的理论基础主要包括:双通道加工理论、信息加工理论、建构主义学习理论和系统科学理论;主要有以下六个基本特征:两个过程、三个通道、信息传播与加工的四个阶段、学习与传播环境、多媒体学习过程的内外反馈及多媒体信息在整合过程中存在比对环节。

The frequency of interactive behaviors which happened in the process of multimedia learning is becoming higher and higher. The essence and morphology of multimedia learning have been deeply changed by interactive behaviors. Meanwhile, the process and essence of multimedia learning have been entirely and effectively depicted by the three-channel cognition-propagation model. The cognitive-propagation model of multimedia learning is mainly based on dual-channel processing theory, information processing theory, constructivist learning theory and system science theory. The model has six basic characteristics which are two processes, three channels, four stages of information propagation and processing, environment of learning and propagation, internal and external feedback during the processes of multimedia learning, existent intercomparison links of multimedia information in the integration process.
