This concluding chapter synthesizes insights across the volume and introduces our Praxis-Infused Transperspectival Model of Agency in Language Teaching (PTMALT). Building on critical and relational frameworks, the model conceptualizes teacher agency as a dynamic praxis shaped by temporality, relationality, ideology, affect, identity, and structural conditions. Rather than offering a static or linear framework, PTMALT provides a generative lens through which the complexity, tension, and possibility of teacher agency can be understood. Drawing on diverse chapters, we argue that language teacher agency is not merely responsive but transformative and must be studied and supported through justice-oriented, context-sensitive, and emotionally attuned lenses. The model also highlights the ethical dimensions of agency and its entanglement with identity, ideology, and resistance. The chapter outlines how PTMALT can inform future research, teacher education, and pedagogical practice, serving as both an analytical tool and ethical call to action for scholars, practitioners, and policymakers committed to equity and transformative change in language education.
