This article explores how the computer-mediated communication (CMC) tool of blogging served as a teaching and learning tool about diversity and inequity in English education. It analyzes the blog writings of two preservice teachers who used their blogs as a space to encourage themselves and their peers to consider racial, linguistic, and other forms of diversity and inequality, and what these issues meant for English education. The analysis advances understandings of the potentials and limits of CMCs to foster dialogue and knowledge building among preservice teachers in relation to diversity and inequality in education.
