再論混合權利：一種最新的有關交互的理論定理

Getting the Mix Right Again: An Updated and Theoretical Rational for Interaction

上期我們對特里˙安德森博士進行了專訪，本期將刊登安德森博士所提出的有關交互的理論定理──交互等效性原理。文章首先對遠程教育中的交互進行了界定和評價，其次提到交互和教育的關係、交互模式；然後作者提出交互的等效性原理，以及對交互性水平進行評估；最後展示了等效性原理的應用案例。

We interviewed with Dr. Terry Anderson Last issue. We will introduce his theoretical rational for interaction──equivalence of interaction. Firstly， the article defines and evaluates interaction in distance education. secondly， it talks about the relationship between interaction and education， the models of interaction. Thirdly， the author puts forward to the equivalence of interaction， and evaluates the level of interactivity. Finally， the article presents the applying cases of equivalency theorem.
