This document discusses the relationship between educational theory and classroom practice in teaching English to speakers of other languages (TESOL). It provides an overview of several learning theories (e.g. behaviorism, constructivism, socioconstructivism) and how they can inform practical teaching approaches and activities. The document also examines concepts related to language acquisition, such as comprehensible input/output, the zone of proximal development, and reducing foreign language anxiety. Overall, it aims to bridge the gap between theory and practice in TESOL by offering specific classroom applications and examples based on established learning theories.
