| Since 90's in the 20th century, Europe, United States and other developed countries have put in "study with particular themes" and started many related projects; while in China, with a new round of curriculum reform, research-based learning and curriculum development has become a big matter of the reform of basic education. The issue stems from the project on modern educational technology named "151 Project" held by Guangdong Province, whose main content is to set 100 special study sites across the province, construct 50 public resource libraries and develop 100 studies of the use of online resources based on teaching reform during the "Tenth Five-Year" period. In this paper, the guidance of exploratory learning strategies, Web-mediated learning system feature, Deng Yanda's socialist ideology, human rights theory, economic theory and so on closely related to the development of contemporary China has been given a focus.Teaching based on information technology aims to foster the spirit of innovation, research ability and practical ability, which emphasizes on allowing students to learn through research, to learn to analysis, research, and finally solve the problem. During this process, students' scientific attitudes, values, as well as the spirit of innovation, innovative thinking, and creative ability are developed.In this paper, based on the analysis of the current learning system at home and abroad, the development of the context of inquiry learning and the characteristics of inquiry learning and thematic learning which take WEB as a basis, the strategies of inquiry learning is designed and realize a thematic learning system based on "Deng Yanda Thought" and the use of WEB technology. Systematical analysis and functional design of special study then was made.In the following sections of this paper the technical realizing of the use of exploratory learning and the design of security mechanisms in the system are given in detail. The system uses ASP + XML to build the database and data saved with SQL Server 2000. In the design process during the process of designing, three-layered B/S structure are served as the basis, and with a consideration that when the learners study with the help of this system, the exchange of the data are very frequent and during this process the data is impossible to be saved, so this paper suggest using XML to solve this problem. The application system carries out the style cooperating with the learner when probing into nature study with interactive large amount of data of system server, operation at every time all requires that the secondary data base extracts and then transfers end to the customer way does not preserve data in the middle. XML, the main body of a book, is applied to carry out the customer communication between end and the WEB server, using XML to sell a data at reduced prices. Information ending on alteration in customer carries out slow existence. Transmission using a data has avoided in large amount, repeating delivery and fetching in the customer between end and the server, have reduced server burden and error rate.In technology, B/S structure can make up for the disadvantages of C / S structure such as the large amount of program development, maintenance difficulties, and is hard to guarantee the security. The implementation of ASP technology still has certain defects, for example, when many user visits the network, the burden on the server is very heavy. These issues also need to address in the future development and suggest using a more perfect and securing ASP.net to replace the ASP to build the system.Finally, the contents of the study are summarized, and the purpose of topic-based learning system is to provide learners with a web-based thematic inquiry digital learning platform, emphasizing the subjectivity of the learner to explore, and to find the solution, and to achieve their own methods for building the system. Long-term concern and study on the application, implementation and executive efficiency are deserved. |
