The use of technology in the educational setting can provide support for professional development early in a teacher's career. The purpose of this qualitative exploratory study was to examine the use of an electronic discussion board in a field-based block of courses as a place where 17 preservice teachers could share experiences and ideas. The researchers examined the nature and development of the discussions over one semester. The study found three major benefits: (a) computer mediated communication extends discussions beyond the classroom; (b) the discussion board became a place for professional support and community; and (c) preservice teachers' reflective thinking developed over time as a result of the discussion board. The electronic discussion board appears to be a promising way to enhance and support existing structures for preservice and inservice teachers' professional growth. (Contains 1 table.)
