The Design and Implementation of English Learning System in Open and Distance Education

摘要

Through the research on mobile learning and the status of related technologies, this paper proposes the design of mobile English learning system and analyzes its feasibility and implementation in open and distance education. The author firstly discusses the concept and technology of mobile learning and the development and application of mobile widget which integrates into web to provide learners with efficient learning environment. Then the theory analysis and demand analysis of mobile English learning system are conducted. On the basis of the pilot study, the design of the system is divided into four-layer structures and constructed by using Nokia Web Run-Time (WRT) platform technology upon mobile widgets. The function in the mobile terminal needs to be achieved by the main modules of online testing, video on demand, English translation and dialogue scenes. The Content Management System (CMS) server applies to Windows Apache + Mysql/MariaDB + Perl/PHP/Python (WAMP), by which establishes a database so that the mobile terminal within the application package can send a request to the server and return data through a Uniform Resource Locator (URL) path. The mobile English learning system, through the reasonable analysis and design, is easily accessed to the distance learners and realizes scalability, security and operational convenience.
