Technology educators at all grade levels are engaged in research. Some technology educators conduct informal research, while others implement formal, authentic research in their classrooms. The purpose of this chapter is to showcase action research in technology education as a method to authentically investigate problems technology educators may need to address in their classrooms. Action research has been defined for the technology educator, as well as the benefits and challenges of conducting authentic research. Further, the content of this chapter focuses on the approaches of action research, developing a research plan, and contextualizing action research in engineering design.
