Mapping doctoral dissertations in an educational leadership programme: A longitudinal examination of knowledge construction in the last two decades

This paper offers a meta-analysis scoping study of doctoral dissertations completed in the last 20 years in one doctoral programme of Educational Leadership (EL) at a higher education institution in Texas, aiming at identifying topical foci, epistemology, methodology and main themes. Therefore, we systematically collected, documented, securitised and analysed completed dissertations following the steps identified by PRISMA guidelines. The review aimed to answer the following four questions: (1) What are the general trends of doctoral dissertations in the studied programme? (2) What is the topical foci of these dissertations? (3) What are the prevailing epistemological constructs and genres informing this work? (4) What are the gaps in this research focus within the scope of educational leadership and policy? Based on our analysis, four main key themes were identified: educational leadership and policy, public education, equity and social justice, and race and ethnicity. Further implications, utility of research and future dissertations in educational leadership in this programme and other similar programmes are fully discussed.
