Lesson planning and implementation of those plans are complex and cognitively demanding for English Language Teacher trainees preparing for the profession. Many find it difficult to develop a lesson holistically and to maintain alignment across aims, procedural steps, and evaluation when planning and implementing a lesson. We attempted to address this problem by establishing a model of trainees' action that included their deliberate metacognitive structuring of a lesson both in planning and review phases. Data from a first exploration of student thinking elicited by the model indicate positive shifts in trainees' holistic thinking and a student-centeredness in the critical perspectives they took in both planning and review.
