Action research is a change management tool. It is a type of case study that teachers/educators/those involved in the school process use to research their own practices, how students learn, or how their particular school operates.
"Action research involves a systematic process of examining the evidence. The results of this type of research are practical, relevant, and can inform theory. Action research is different than other forms of research as there is less concern for universality of findings, and more value is placed on the relevance of the findings to the researcher and the local collaborators."
