The author presents five types of educator practitioner inquiry: pragmatic research, lesson study, appreciative inquiry, collaborative autobiography, and equity research. Examples of each type of research carried out by K-12 practitioners are provided. The particular type of research that educators select should depend on the purpose of the research, preference of participants, researcher and facilitator capacity, and available resources. Predictors of success include commitment of researchers and leadership, professional learning on how to use the type of research selected, time to carry out the research, continued support, and recognition of the research and the researchers.
