'Re-thinking equity: the need for a multidimensional approach in evaluating educational equity through TIMSS data'

Abstract Background In recent years, data derived from international large-scale assessments have significantly influenced the discourse surrounding educational equity. However, the use of such data has often neglected the full spectrum of dimensions that equity encompasses, while being limited to exploring the relationship between achievement variations and student background. This approach, however, constrains our understanding of the rich notion. Methods This paper aims to contribute to the advancement of current research by advocating for an alternative approach that encompasses all relevant dimensions of equity and examines their impact on both achievement and motivational outcomes. A cluster analysis manifests itself as the designated method to employ, as the concept of equity remains theoretically challenged and the detection of data patterns can serve as a strong step in its multifaceted inquiry. Moreover, this method enables us to incorporate the multidimensional concept in a country-level context. Results Employing data from the Trends in International Mathematics and Science Study at grade four, this paper presents five distinct clusters of educational systems that illustrate diverse equity configurations. Notably, none of the identified clusters consistently scores high or low on all equity dimensions. This suggests that all of the clusters perform inconsistently to different degrees across the dimensions of equity. Furthermore, no single cluster emerges as superior to the others across both outcome measures. Conclusions These findings shed light on the intricate interplay between equity, achievement, and motivation within the examined educational systems. The unique configuration of the equity dimensions within each cluster underscores the importance of adopting a nuanced evaluation of equity, which can enhance our understanding of equity patterns.
