Research on Development Trend in Interdisciplinarity of Educational Technology based on Web of Science-covered Data

The purpose of this study is to provide references for researchers in the fields of educational technology (ET) and other sciences such as natural science, humanities and social sciences in their cross-integration research, and then promote interdisciplinary research and development of ET. To this end, this paper, based on the literature on Web of Science and related data in different subject category, applies the literature metrology and visualization technology of mapping knowledge domains, and then deeply reveals the interdisciplinary development of international ET from a multi-dimensional perspective. The study found that “computer science in interdisciplinary applications” are most closely related to the ET, with the longest interdisciplinary time. In addition, the knowledge source of ET is extensively covered, and its knowledge source discipline is far more than its own application field. Thus, it is necessary for ET to discover the characteristics of computer-related disciplines in terms of application methods and application fields and further improve its application range.
