The Design And Research About The Learning Environment Of Hypermedia Based On CFT

The teachers are the dominators, and the classrooms are the main places to teach studentsin traditional learning environments, so students' learning is closed, passive and lack offlexibility in that case. In recent years, with the rapid development of technology of computersoftware and hardware, and the universal application of operational interface of humanization,and the vigorous development of the Internet, the application of computer technology ineducation is more broader, and it's application value to education is much greater, whichmakes the traditional learning environments change a lot. It's been the mainstream ofdevelopment about theories of learning environment that we should integrate computertechnology, use powerful storage space and search capabilities unlimited of computer tostimulate a new kind of learning environment for learners' individual learning.With the development of the theory of learning, the architecture of learning environmentis also changing day to day. Constructivism provides theoretical foundation for thearchitecture of Learning-Centered learning environment;so many psychologists have createda variety of styles and viewpoints of constructivism by conducting more in-depth studyaccording to their respective issues of concern to learning and teaching based onconstructivism. In these schools, Cognitive Flexibility Theory (CFT) provides the mostappropriate theoretical models for the design of learning environment enhancing learners'cognitive flexibility, which thinks that it must not only take into account the importance ofteaching basic concepts and principles but also take into account the importance of thedevelopment of learners' cognitive ability, and the flexible capacity of problem-solving in thenew environment. The views on the learning environment of CFT are important to construct anew kind of learning environment.This dissertation firstly expatiates the contents and the theoretical foundation of CFT bydetailing the concepts of CFT, the classifications about learning stages of CFT, the view ofteaching of CFT, the cognitive tools based on CFT, and the relations between CFT andteaching of internet;then We made the outlook of learning environment through carefulanalysis according to the view of the resources outlook on the learning environment of YangKaicheng named "Expert of Instructional Design" and the view of the Integrated Systemsoutlook on the learning environment of M.J.Hanafin based on Constructivism, which includesfour parts: Learning content, Learning resources, Cognitive tools and Interaction andexchange. Then we made the outlook of Hypermedia learning environment by integratingCFT with Hypermedia based on the expatiation of Hypermedia, that is, Hypermedia learningenvironment is a Multimedia environment which is composed of learning content, learningresources, cognitive tools, interaction and the exchange.Then we integrate CFT into the learning environment based on hypermedia, and bringforward the view of specific composition, learning characteristics, learning processes,ultimate goals and the principles of design of the Learning Environment of Hypermedia basedon CFT, moreover, we bring forward the design strategy of system and the design model ofsystem through designing learning content, learning resources, cognitive tools, interaction andthe exchange of the Learning Environment of Hypermedia based on CFT.Based on the above researches, an example of Hypermedia learning environment basedon CFT is designed and developed according to the design strategy of system and the designmodel of system of the Learning Environment of Hypermedia based on CFT, which is UnderB/S architecture, developed at Windows 2000 Server and IIS5.0 platform. The user webinterface is developed by Dreamweaver. Page style and color scheme are controlled by CSS.Web interaction is programmed by JavaScript. The system basically implements the designobjective and run stably and credibly.
