The goal of CAR is to improve your own teaching in your own classroom (or your department or school). While there is no requirement that the CAR findings be generalized to other situations, as in traditional research, the results of classroom action research can add to the knowledge base. Classroom action research goes beyond personal reflection to use informal research
practices such as a brief literature review, group comparisons, and data collection and analysis. Validity is achieved through the triangulation of data. The focus is on the practical significance of findings, rather than statistical or theoretical significance.
