About the development of learning environment system to be used in the class, the followings were shown : the dynamic link mechanism on Web, the methodology to utilize tags to build the flexible learning environment system with Web-DB connection, and a way of system development which is effective in school education.We proposed new teaching method in which this system was utilized. We practiced the classes in which learners pursue knowledge and own those jointly in the Period for Integrated Study as well as the existent subjects. In the elementary school, the junior high school and the high school, the classes were held and we got the following results.1.Based on the "The Zone of Proximal Development" of Vygotsuky L.S., the methods of teaching and instructional design were established.2.A tag can add various meanings to the information created in the system in the learning process. We also cleared the form of new communication that becomes possible by this method.3.We mounted the next three functions on this system by using the meaning expression mechanism with the hyper-link. (1)System can change some output forms on the monitor from to each other. (2)Communication function. (3)The visualization of thinking.4.The results of the classes which were carried out in 2002 and 2003 years were put into documents of instruction and digitized for the database.
