This article presents a methodological approach to educational psychology research in which researchers engage in collaborative transformations of educational practice while developing theory concerning the societal and scientific relevance of these transformative processes. The theoretical inspiration for this approach stems from…

During this inquiry, I describe my journey as a beginning arts-based researcher, using this methodological approach to explore the "peak experiences" of five, second-grade gifted students in a general classroom.

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…
