The Approach Of Device Independence For Mobile Learning System

Mobile learning is transforming the way of tradition education. But most of e-learning system and contents are not suitable for mobile device. In order to provide suitable mobile learning services, the approach for self-adaptation is proposed in this paper. Firstly, the formal definitions of context and its influence on learning service, including NCxt, side S, weighing Q and adaptation coefficient E, are presented Then, using the approach, the mobile learning system is constructed The example implies this approach can detect the contextual environment of mobile computing and adapt the mobile learning service to the mobile learners' device automatically.
