Background: Fair comparisons of educational systems in large-scale assessments can be made only if the differences in curricula have little impact on the outcomes. This study investigated the sensitivity of science achievement rankings to varying degrees of curriculum implementation in the Trends in International Mathematics and Science Study…

While professional development has been emphasised in many countries, few comparative studies have examined the degree of teachers' participation in professional development and its effect on teachers. Using the TIMSS 2007 data, this study analyses to what extent teachers participated in professional development in 50 TIMSS countries and examines…

The "world culture" framework posits a convergence in the organisation of education across the world. On the other hand, scholars observing teaching practices inside classrooms find significant variation among nations and regions of the world. This study examined the global change patterns of classroom practices at the between- and…

The aim of the International Society for Technology, Education, and Science (iHSES) conference is to offer opportunities to share ideas, discuss theoretical and practical issues, and connect with the leaders in the fields of "humanities," "education" and "social sciences." It is organized for: (1) faculty members in…

Research on educational quality has been scarce in the Middle East and North Africa (MENA) region, whereas the debates over educational quality date from 1966 in the USA with the Coleman Report. Fortunately TIMSS (Trends in International Mathematics and Science Study) starts to fill this gap by providing data on students' achievement and for many…

Science schooling enjoys high status. Scientific capability is perceived as critical in underpinning economic success in advanced societies. Science achievement, at all levels, has become a global competition in which nations want to be seen to triumph. Governments periodically pay close attention to science education with a view to ensuring it…
