Abstract :
This paper examines various criteria that have been proposed for evaluating the increasing number of empirical studies carried out using qualitative research methods, and it demonstrates how such criteria may privilege certain forms of qualitative research while excluding others. A broader disciplinary view is taken by defining qualitative research, and by discussing in more detail the two qualitative traditions that have achieved prominence in applied linguistics, ethnography, and conversation analysis. Then, select existing evaluative criteria for qualitative research proposed by applied linguists, as well as additional criteria developed outside applied linguistics, are examined. Finally, the issue of criteriology is considered, on which some of the assumptions underlying the existing evaluative criteria are based. To conclude, this article discusses the complex relationship between research method and evaluative criteria and the role of professional journals in establishing and validating such criteria.
