Globalised student achievement? A longitudinal and cross-country analysis of convergence in mathematics performance

With the aid of longitudinal country-level data from five IEA TIMSS assessments (1995-2011), the current study addresses the issue of the globalisation of curricula and achievement. To explore the hypothesis of global convergence, we study performance in four subdomains of mathematics. Using regression with fixed effects for countries, we consider whether the variation of subdomain scores decreases globally over time. Additionally, we explore qualitative differences in performance profiles using latent class analysis. Our results provide little evidence for a global harmonisation of student achievement. Rather, for regions with a similar language and culture, we observe similar strengths and weaknesses in mathematics content areas. Furthermore, these patterns remain stable over time. Directions for future research include the exploration of global trends in aspects of attained curricula for other subjects, and the use of information on school achievement.
