The Content of Educational Psychology: an Analysis of Top Ranked Journals from 2003 Through 2007

Educational psychology as a field of study has encountered a lack of distinction by overlapping with other fields of study or disciplines. Consequently, educational psychology continues to have difficulty claiming jurisdiction over bodies of research knowledge and has been encroached upon by other more crystallized disciplines. The purpose of this study is to examine the research literature published across top-ranked educational psychology journals to identify the common ground and current trends in research content and to identify those areas that can be reclaimed by the discipline as its own. Overall, 758 articles published in six journals from January 2003 through December 2007 were included in this study. A combination of statistics-based and linguistics-based methods were used to determine how frequently terms occur in the data and establishing a semantic network which created a probabilistic analysis of the co-occurrence of terms resulting in a constellation of terms showing the relationship and relative importance of the categories of terms. The results showed a consistency of research categories suggesting that in spite of reports to the contrary, there is a collective agreement among educational psychologists demonstrated by the empirical research in the field.
