Embedded in social worlds, education systems and research reflect distinct national trajectories. We compare two contrasting traditions of educational research (ER). Whereas British ER exhibits a multidisciplinary and pragmatic character, German ER reflects pedagogy and mainly humanities-based traditions. Yet, in both countries, policymakers' growing demand for evidence in ER resulted in increased funding, specific research programs, and mandatory large-scale assessments. These have reshaped the field, suggesting more similar ER agendas. Based on a comprehensive original dataset of basic ER projects funded by the main grant-making agencies in both countries (2005-2015), we analyze five dimensions: levels, objects, disciplines, methodologies, and themes. We find epistemic drift, with partial convergence characterized by a multi-level focus, multidisciplinary approach, strongly empirical and quantitative methodology, and a premium on teaching and learning themes. The cases remain distinct in exploring systemic questions in a wider contextual frame (UK) or concentrating more narrowly on the individual learner (Germany).
