This document discusses a study that compares perspectives of elementary school teachers in South Korea, Japan, and Taiwan towards communicative language teaching (CLT) activities. The study uses video recordings of CLT activities in classrooms to elicit discussion among teachers. Key findings include that teachers face challenges in understanding what constitutes teaching for communicative purposes, the role of developmental factors in English language learning, and how to harmonize learning/teaching with sociocultural context. The study analyzes teacher perspectives through the framework of sociocultural theory, which views language learning as situated within social and cultural contexts.
