The Use Of Interactive Tv Technology To Build In The Exploration Of The Distance Learning Model

According to the analysis of the current state of the system of the modern distance education, the thesis can draw a conclusion that the modernization of the interaction is the lifeline and the impetus of the distance education. Based on this, the interactive television technique, a high-tech digital television technique, which is being most concerned is analyzed systematically. What' s more, the plan of reformation concerning with net platform of this technique is put forward. On this basis, a distance teaching model constructed by the interactive television technique will be deigned based on the bidirectional CATV. The aim is to impair the deficiency of the interactive difference of the modern distance education; to make the learners become the real main body in the process of learning; thus reflect the creativeness of the learners and complete the meaning constructivism.The thesis can be divided into three parts:Part 1: The technique and the development of the interactive television are introduced in detail. The former includes: the formation of the interactive television and the key techniques; whereas the latter includes: the current state and the future tendency, the field that it can be applied and the advantage of the usage of the interactive television on the distance teaching.Part 2: According to the review of the history and the analysis of current state of the system of the modern distance education home and abroad, the thesis can draw a conclusion that the modernization of the interaction is the lifeline and the impetus of the distance education. Besides the review and analysis, the characteristics and it' s formation of the system of the modern distance education will be introduced; several media used for the distance education willalso be compared and analyzed. That the traditional broadcastiong and TV will be taken place by the interactive television as the medium of education is the tendency. Distance education of the interactive television would be popular among teachers and students.Part 3: The theoretical basis of the distance education which makes use of the interactive television is the Constructivism. Beginning from the discussion of designing principle to the function , the analysis and remaking of the net platform that can be used to realize the model, the distance teaching model based on the bidirectional CATV and constructed by the interactive TV technique is put forward.
