Ajax Technology-based Online Learning Environment

With the rapid development of information technology and the widespread application of e-learning, e-learning environment construction also becomes more and more important, especially the Web2.0 technology's arrival presents the new challenge for the network information management system and e-learning theory. In order to promote learning, and to explore the Web2.0-based learning environment construction, I analyze the deficiencies of the current learning environment construction and David H. Jonassen's Constructivism learning environment model in the paper, and explain huge superiority of the Ajax technology in detail in the learning environment construction, propose a technology Ajax-based online learning environment model. Through the refinement of the model elements, I explore the Ajax technology-based learning environment system module and the module design.This article first reviews the history of the e-learning Environment. It shows the status quo and Web2.0 application of state, and then introduces the major work of this paper and the focus of the study.The second chapter is the Web2.0 content and the Ajax technology. This chapter discusses in detail the main elements of Web2.0 and thinking, Ajax technology components and principle, the question which needs to pay attention in the Ajax technology application. Finally lists the Ajax technology applications typical case.Chapter III discusses in detail the online learning environment-related knowledge. The sections of the main elements include: the learning environment-related concepts, the theoretical foundation of e-learning environment Construction, the guiding principles of e-learning environment Construction as well as influence of Web2.0 technology on learning environment.Chapter IV is the Ajax technology-based learning environment-related content. First of all, I describe the non-Ajax-based e-learning environment system. Two traditional cases are very representative, the one is based on the C / S, although the system has a number of advantages, with new technologies rapidly emerging and the level of user application continuously raising, B / S is faster. Furthermore, B / S structure of the system will give users greater convenience; the other case is based on B / S. The following sections show Ajax technology-based model design of online learning environment.Chapter V is a brief summary of the article. I forecast Ajax technology application prospect and the e-learning development trends.
