Previous studies differed largely in their findings concerning the relationship between principal leadership and students' mathematics achievement because of the complexity of principal leadership. As Hallinger and Heck's theoretical framework showed, principal leadership was comprised setting vision/goal, school management, and school climate…

This research explored the relationship of principal leadership and teacher professional learning in China and Thailand. The authors tested a conceptual model in which teacher trust and agency were proposed as mediators of the effects of the principal's learning-centered leadership on teacher professional learning. Common survey measures had been…

Ageism is recognized as a significant obstacle to older people's well-being, but age discrimination against younger people has attracted less attention. We investigate levels of perceived age discrimination across early to late adulthood, using data from the European Social Survey (ESS), collected in 29 countries (N = 56,272). We test for…

The foundation of school success is laid early in children's lives. Consequently, assessments of academic precursors may help to identify children in need of additional support. Such early assessments could also be interesting from an international perspective when educational systems are compared. This analysis is used to inform on the…

This article argues that strong interrelations between methodological and theoretical advances exist. Progress in, especially comparative, methods may have important impacts on theory evaluation. By using the example of the "Varieties of Capitalism" approach and an international comparison of higher education systems, it can be shown…

Background: Influence of external factors in general, and socioeconomic background factors in particular, on traditional reading performance has been extensively researched and debated. While traditional reading is well investigated in this respect, there is a lack of studies on equity aspects related to digital reading achievement, in spite of…

This study explored the validity of the Utrecht Work Engagement Scale in a sample of 853 practicing teachers from Australia, Canada, China (Hong Kong), Indonesia, and Oman. The authors used multigroup confirmatory factor analysis to test the factor structure and measurement invariance across settings, after which they examined the relationships…

The primary goal of this study was to test a credibility-learning model in U.S., Chinese, German, and Japanese classrooms. Using structural equation modeling, an etic credibility-learning model was generated from the common significant paths of the hypothesized model across the four cultures. Teacher credibility showed only an indirect…
