“…Mathematics, as one of the core tests of TIMSS, has also been widely studied. For example, research data collected using TIMSS reveal that girls in Kuwait outperformed boys in Mathematics ( Al-Mutawa et al, 2021 ), students’ achievement in TIMSS has a significant linear relationship with variables related to school factors ( Wardat et al, 2022 ), and the relationship between socioeconomic status (SES) and TIMSS-results in mathematics has two mediators among Norwegian fifth graders ( Østbø and Zachrisson, 2022 ).
