异步交互工具的交互潜能——一项关于异步交互中教学交互结构模型的研究

Interaction Potential of Asynchronous Interactive Tools：Research on Instructional Interaction Structure Model in Asynchronous Interaction

本文将社会网络分析法（SNA）用于两个教学案例，从教学交互的角度对异步交互中教师和学生组成的交互群体的交互模型和结构进行了系统的分析。研究认为，为了更加有效地利用异步交互促进在线学习，教师需要有针对性地对在线学习中的交互进行设计和准备，并在教学过程中充分发挥学生在交互过程中的主动性，提高对学生的关注程度。此外，结合使用多种交互工具，也可以有效地提高在线学习中教学交互的质量和效率。

This paper reports on two instructional cases using Social Network Analysis（SNA） and in view of instructional interaction systemically analyzes the interactive model and structure of the interaction group including teacher and learners. In order to promote online learning by effectively using asynchronous interaction， the teacher should design and prepare for the interaction in online learning， then fully bring the learners’ initiative into play in process of instructional interaction， and finally improve the attention level on learners. What’s more， using different interactive tools is also efficacious in advance the quality and efficiency of instructional interaction in online learning.
