課程設計與媒體選擇

Course Design & Choice of Media by Applying the Theory of Transactional Distance

本文介紹了包括約850名學生在內的一系列經驗研究，表明學生的文化背景與母語、性別和年齡差異要求課程設計必須具有靈活性，並應用交互距離理論說明在課程設計中如何選擇作合適的教學技術。本文提供的曲線表明了學生的文化與母語、性別與年齡因素對其在線和離線閱讀英語的速度的影響狀況。為避免由於文化差異帶來的學生負擔加重的不公正狀況，應採用超文本形式修正課程設計，根據交互距離理論選擇媒體，尤其是相對於異步媒體的同步媒體。

This Paper presents a series of empirical studies involving approx 850 students to show how flexibility in course design should be informed by the student’s culture and native language， gender， and age， and explains how to decide on the most appropriate learning technology in course design by applying the Theory of Transactional Distance. Curves are presented to show how academic English reading rates on-line and off-line are affected by the L1， gender， and age. To prevent inequitable culturally-distinct overload， course design should be modified using hypertext. Choice of media-in particular synchronous versus asynchronous media-is decided according to the Theory of Transactional Distance.
