Design of a college english mobile learning system based on CAD model

Abstract

With the development of mobile Internet technology and the adventof the information age, people's demand for mobile learning is growingand the studies on mobile English learning platform are also drawing more andmore attention. In this article, firstly, the background of mobile learning is introducedand a Conversation-Activity-Distribution theoretical model, CAD, isproposed with activity theory, situation cognition theory and distributed cognitiontheory as the cognitive basis. Then, the students' demand and expectationsfor implementation, function and content of the mobile learning system arelearned by the combination of experiential researches and questionnaire surveys.A model of college English mobile learning system is proposed based onthe CAD model, the overall structure of the model is discussed and its variousfunctional modules introduced. With vocabulary learning as case design, theprocess design, function design and adaptive design of the system are introducedand the functional interface to the system demonstrated. Theoretically,this article enriches the theoretical basis of mobile learning and improves themethods of mobile learning system. Practically, through the studies on relatedlearning theories, it puts forward a CAD theoretical model and carries out thecase study on English vocabulary, which are conducive to the popularization ofmobile learning in English learning and the improvement of teaching quality.
