The role of power in an English-as-a-second-language classroom has yet to be fully explored by an action research practitioner, especially in a Malaysian higher education setting. This study aims to contribute to this gap by working within an academic literacies perspective to teaching academic writing, which propagates the understanding of power-relational, socio-cultural and epistemological conditions for effective teaching and learning. As the teacher in this classroom, I focus on how power-relational conditions play out. To activate the power conditions, I used a teaching principle in Teaching English to Speakers of Other Languages (TESOL)-negotiated interaction to reduce power-based mismatches between participants in a teaching or learning relationship in my classroom, drawing upon Kumaravadivelu's work on post-method pedagogy for TESOL; that is, not being bound by any specific method of teaching. In analysing the different types of power that were operational in my classroom, wider implications of power that operate beyond the classroom level and how they impacted teaching and learning decisions were found to be highly illuminating. The action research methodology used for this study enabled me to reflect critically on my detailed diary recordings and student letter and interview collections, which in turn impacted on my teaching decisions as each teaching cycle was completed. My reflections also help shape my evolving identity as a teacher-researcher throughout this ongoing Malaysian action research journey.
