Metaphors offer a lens through which language teachers express their understanding of their work. Metaphor analysis can be a powerful reflective tool for expressing meanings that underpin ways of thinking about teaching and learning English as a second/foreign language. Through reflecting on their personal teaching metaphors, teachers become more aware of the beliefs that underpin their work. This paper reports the reflections on the prior beliefs of three experienced ESL teachers in Canada through the use of metaphor analysis. The paper attempts to explore the prior beliefs of the three experienced ESL teachers in Canada through metaphor analysis by using the Oxford et al. (1998) framework as a theoretical lens in which to gain understanding of the use and meaning of these metaphors. Results indicated that all three teachers used a total of 94 metaphors throughout the period of the group discussions and interviews, and that the metaphors used most were those related to learner-centered growth, followed by social order, then social reform.
