理论扩展——教育技术现代化的内在动力

Theoretical Expansion - the Internal Motive Force of the Modern ization of Educational Technology

在教育技术理论的发展过程中 ,教育技术一方面从教育学、心理学、传播学、系统论、控制论、信息论等有关领域的研究成果中汲取营养 ,实现自己的理论扩展 ,又反过来指导教育技术实践。教育技术就在这认识———实践———再认识———再实践的往复循环中不断提高和发展。

Educational technology assimilates for its theoretical expansion the scientific achievements in pedagogy, psychology, communications, information science, cybernetics, and system theory and in turn serves the educational practice. It is in the endless cycles of knowledge and practice that educational technology keeps improving and developing.
