Design And Development Of Online RIA-based Learner Experience Learning System

Learners experience is a new research subject in the field of educational technology .Throughout the past decade on the progress of the learners experience ,we found that learners experience on the related research topics are just emerging in the field of educational technology. And gradually , educational technology scholars and computer experts are concerning the field .Through the current study, we found that online teaching methods are flooded all corners of the network, the network learners prefer written materials to online learning software.Because of lacking network experience of learners online, this phenomenon is occur. Throughout the using of online learning software, online learners feel that not easy. It is very serious that the interactive coupling between different functional modules and with single-page style, it is difficult to maintain a long attention prone to visual fatigue, and may even be dense pages of text narrative troubled by the focus of the page to seize the contents. All of those are signs of lacking of performance.Solving the problem of inadequate education is a continuous concernning subject to people in the field of technology. In this paper, based on the learner experience of RIA technology design and development of online learning system described as an example analysis the feasibility of RIA technology to solve the problem of inadequate network of learners experience, with a view to change the status.From a technical perspective, the emerge of RIA technologies provides a solution for experience web-based learners. RIA technology to the traditional B / S application software client program is divided into two tiers: page displays the layer and the RIA engine layer. Page displays the layer is mainly responsible for the content of the page to display and interact with the network interface of learners for online learning system to achieve dynamic interaction and extensive page style effects; RIA engine layer is mainly responsible for initializing the local component, reducing the pressure of the server-side, sending the interaction requests to the server-side by asynchronous forward on page displays the level.From the point of view of course content, the contents of the page displays of online learning system is support tools for network learner. This paper analyzes the principles of clear and concise we should pay attention, highlighting courses focus on knowledge when the page content is displayed to help learners grasp knowledge. Network Learners learn the content of the course by online, learning the knowledge in detail after class. Online learning system provides online testing capabilities to help network learners what they have learned the timely review and consolidation point, to what they have learned to understand the extent of knowledge quantitative evaluation.After the requirement analysis, system design, system development, deployment implementation of the online learning system complete, the network learners come into use and fill in a web experiences learners evaluation questionnaires, analyze survey results, and provide strong evidence and recommendations for on-line iterative development and perfection.The structure of the paper and the contents of each chapter summarized briefly as follows:The first part of Chapter Introduction begins from the background of this study with a web-learner online learning in the process of the real problems encountered an entry point for research. Through a simple question analysis ,textual the feasibility and necessity of the research, and statements the status quo, the research objectives of this study and the major research methodologies of the online learning system at home and abroad who focus on learner experience.After thinking clearly, it is the time to study the content of the classification, sum, sum up to form the basic framework of this study.Chapter II, theory as a prelude to the user experience and to learn from the successful experience to define the concept of learner experience and influencing factors. From the technology point to analyze the feasibility of RIA technology can achieve the learners experience of the desired effect. From the emotional design and constructivist learning theory to textual theoretically the system design and development,which this RIA technology-based learning experience for the online learner.Chapter III analyzes the obstacles and difficulties in online learning at this stage in online learning experience ,and determines the network's overall needs and preferences. Discussed what based on analysis of the learner requirement analysis and curriculum to develop the design principles and to guide the subsequent design and development process.The fourth chapter describes the client-side design ideas of the RIA technology in the B / S application software development, analysis the superiority of the RIA technology in the development of the client , changes the traditional B / S application of a single "request - response" model, achieves the client's asynchronous interaction,and ensures the continuity of the network experience for learners. According to RIA technology clients design ideas, I design a process model for learner experiences of the online learning system to provide reference to the program. Chapter V, after completing initial requirements analysis and determining the design process, we access to the systematical code development and post-implementation evaluation phase. This chapter focuses on learner-based RIA technology experience of online learning system development process design, system architecture, the implementation of main function modules code issues. After on-line learning system development completing, the deployment of on-line for the network of learners to use, taking a number of Web-based Learners sample for an object of investigation,then making evaluation questionnaire and experience evaluation who use the online learning system.Chapter VI summarizes the main tasks of this study and contribution, and the problems raised in the research ,and determines the follow-up research direction of development.
