This paper investigates the sustainability and the impact of offering the dynamic approach (DA) to schools for more than 1 year in improving student achievement in mathematics (quality) and reducing the impact of socioeconomic status (SES) on achievement (equity). A sample of 56 schools in socially disadvantaged areas in three countries (i.e.,…

There is an increasing interest of policies and projects to adapt boarding schools as a means to provide quality education for educationally disadvantaged students. However, little evidence is available for the effectiveness of boarding schools. The current study examined the boarding effect on primary and middle school student mathematics…

Background: Previous studies have suggested that teachers' frequent use of cognitive activation strategies in mathematics lessons is positively associated with students' mathematics achievement. Aims: This study aims to investigate the possible mediating role of mathematics self-efficacy in the association between cognitive activation and…

Using the International Association for the Evaluation of Educational Achievement's (IEA's) Trends in International Mathematics and Science Study (TIMSS) 2015 data, this brief explores the relationship between teachers' gender and students' mathematics and science achievement, as well as gender differences in science and mathematics teachers'…

The National Center for Education Statistics (NCES) has periodically published reports using results from the National Assessment of Educational Progress (NAEP) to compare the proficiency standards that states set for their students.
