Noting that teachers' research is found in personal journals, professional conversations, computer networking, formal research studies, and publications or presentations, this paper answers, in outline form, a series of questions on the expanding role for special needs educators. These questions are: what "teacher as researcher" means; why teachers are becoming researchers in their own teaching environments; what (or who) the subjects of teacher research are; what some of the most common research methods and designs are that teachers use when researching their environments; how teacher researchers can find and frame a research question; what resources (articles, books, and other publications) can be consulted to learn how to become a teacher researcher, and what sources of support exist for teachers' research; and how teachers can start planning and networking today.
