| Abstract: | In this paper, we define and describe a distance education system model (DES model) after analyzing the development of distance education. The aim of this model is to assist the designers of different distance education system to plan and implement a specific situation. The DES model is composed of five layers, which include physical layer, network layer, transport layer, management layer and implement layer. Each layer consists of different objects addressing issues specific to each layer. Each object consists of one or more methods to be implemented in order to achieve the distance education. Moreover, we analyze the model and discuss the designing distance education system algorithms based on this model. At last, we illustrate the mapping of the model onto a specific learning situation. |
