Based On Network Teaching Mode, A Variety Of Communication Mechanisms

Computer network brings prolificacy revolution to the instruction . It-leads to change in many aspects, including education ideas, instruction environments, teaching methods, instruction organizing form, the relationship among persons and all kinds of actions in the instruction. How to affectively develop the network instruction. It is a new task which is worth researching and discussing. It is focusing attention upon the fields of educational technology and teaching. Harasim pointed out, 'The cross between computer and communication technology and more and more mature in network technology has become the fresh strength in education. It leads to the transformation of the traditional instruction model: a series of new models, a set of successful learning rules in new learning environment, new hopes and expectations in the following. The difference between network instruction and traditional instruction is network learning environment (NLE). NLE is a constructive environment that is convenient to study for students and have much communication functions. In the different communication means supporting, the network instruction not only becomes more enriching, but also the old teaching method becomes more perfect, from the self-query learning model to the cooperative learning model, the resource-based teaching model. The lecture teaching model, the problem-based teaching model and the case-based teaching model become more perfect. They all appear many new traits.From the viewpoint on application objects of network instruction, there are two primary types: one is integration with classes in school, the other is distance learning in network education college. With the project of "school to school connection" spreads, it is required to seek the network instruction model integrated with class instruction. It is very important to construct scientific and effective network model in order to promote the network instruction and facilitate education information process. Meanwhile our country invests to develop distance learning. Searching network instruction model is very important to improve distance education.This dissertation analyzes the instruction model and strategies from network communication mechanism viewpoint. It discusses in theory and practice aspects.With the development of computer network communication, intelligent technology, information technology combined with modern instruction theory, and network instruction applied in practice, it will make the instruction model more and more perfect. This dissertation is only my beginning in network instruction research. Many aspects are not deep and complete. I aspire after the advice and guidance from scholars and experts. I will continue to study in future.
