Research Replication

Abstract

This chapter traces the history of replication research in the field of applied linguistics, culminating in a discussion of current views of replication research as a means of evaluating the internal and external validity of a study, illuminating phenomena of interest, and ultimately, driving both theory and pedagogy forward. It provides an overview of different types of replication studies (exact, approximate, conceptual) with recent examples from the field. Challenges concerning the interpretation of replication results, as well as ongoing controversies over the replication of qualitative studies, are discussed. The author concludes with current recommendations for facilitating replication research, including those pertaining to reporting and data sharing.
