This digest outlines salient characteristics of teacher-led research and its benefits to teachers and students. A discussion of selected resources for teacher researchers, which are available through various components of the Educational Resources Information Center (ERIC), follows the overview. Effective teacher research is an empowering professional development activity that can assist teachers in several ways: (1) it empowers teachers, giving them greater confidence in their ability to individually and collectively promote change; (2) it develops and improves intellectual and technical skills; and (3) it expands career opportunities. Because teacher research is typically driven by a teacher's desire to improve his or her practice, and because it is focused on a specific problem, students generally reap immediate benefits from the teacher's findings. ERIC can assist teacher researchers to plan, implement, and disseminate their research. Specific ERIC resources that may be particularly useful include the ERIC database, the AskERIC Virtual Library and other Internet-based resources, ERIC publications, and subject-specific ERIC clearinghouses. Examples of information from some of these specific resources found within the ERIC system are given, and contact information for identified resources is included. (Contains 16 references.) (IAH)
