Email: choyonj@indiana.edu Abstract The purpose of this study was to conduct a citation network analysis of Educational Technology Research and Development (ETR&D) to examine the trends and issues of the educational technology field’s scholarly community that have evolved in the past two decades. The distinctive features of citation network analysis used in this study derive from a social network analysis approach to see relational and network patterns in the citation data. From this citation network analysis, we obtained the following results: (1) the ETR&D network revealed structural attributes that help us understand the features regarding how the field has developed and how scholarly works have interacted; (2) the most influential papers and scholars in the field were identified; (3) frequently co-cited papers were recognized as having a strong relationship by a few researchers and (4) five cohesive subgroups (factions) generated key research themes in the field including: instructional design, learning environments, the role of technology, educational tech- nology research and psychological foundations. Implications and limitations of the study were discussed for future research. Introduction As the educational technology (ET) field matures, we turn our attention to the literature gener- ated by the scholarly community. Recent reviews in the field have revealed some publication patterns of authors and institutions through citation analysis (Gall et al, 2010; Kirby, Hoadley & Carr-Chellman, 2005; Zaugg, Amado, Small & West, 2011). Citation analysis is quantitative analysis of the literature produced by a field and the relationships among people as evidenced by whom they cite in their published papers (Kirby et al, 2005). Gall et al (2010), through a citation analysis, generated a list of nine symbiotic journals (those that British Journal of Educational Technology Vol 44 No 5 2013 677–694 doi:10.1111/j.1467-8535.2012.01338.x © 2012 British Educational Research Association
