Background: Individual patient data (IPD) meta-analysis allows for the exploration of heterogeneity and can identify subgroups that most benefit from an intervention (or exposure), much more successfully than meta-analysis of aggregate data.

Highlighting the need for teacher education programs to respond to rapidly diversifying societies, this article reports a qualitative metasynthesis of intercultural outreach projects in music teacher education, conceptualizing these projects as a "pedagogy of interruption." Results show that such outreach projects interrupt the…

While reflection has been a common tool for examining the development of teaching and learning practices in the classroom, its use in a language learning setting is still peripheral and minimal.
