近二十年教育技术学研究生的学术取向:阶段、规律与反思

The Academic Orientation of Educational Technology Graduates in Recent Twenty Years:Stage,Regular Pattern and Reflection

教育技术学作为教育学的二级学科拥有大规模的研究生培养体系,纵观2000—2020年的教育技术学研究生毕业论文的学术取向,有助于挖掘教育技术学研究的发展趋势和文化背景,反思教育技术学在发展过程中存在的问题,并给其他相关学科的发展提供借鉴。本文首先运用文献计量学的方法分析教育技术学研究生学位论文的学术图景;其次,从教育技术学的起步阶段、发展阶段、顶峰阶段、成熟阶段深度阐述教育技术学学科不同阶段研究的学术取向;最后,通过LDA主题分析挖掘教育技术学研究生学位论文的主流学术取向,同时为了进一步揭示近二十年来的纵向研究趋势,采用TF-IDF进行数据挖掘以发现和反思其深层次的发展规律。

As the sub-discipline of education,educational technology has large scale postgraduate education system.Making a comprehensive survey of the academic orientations of graduate theses of educational technology from 2000 to 2020 will be beneficial to the digging of the developmental trends and cultural background of educational technology research,the reflection of the existing problems in the development of educational technology,and providing referential significance to the development of other related discipline.This paper,at first,has utilized bibliometric methods to analyze the academic landscape of graduate dissertation of educational technology;the second,this paper has expounded in depth the academic orientation of different stages’research of educational technology from the initial stage,development stage,peak stage,mature stage of educational technology;at last,this paper has dug the main stream academic orientation of graduate dissertation of educational technology through LDA subject analysis.Meanwhile,in order to further reveal the longitudinal research trends in recent 20 years,the paper has adopted TF-IDF to conduct data mining to find and reflect its deep developmental regular pattern.
