This video by Chris from The Language House covers fundamental English teaching concepts. It emphasizes maximizing Student Talking Time (STT) over Teacher Talking Time (TTT) through pair work and clear tasks. Key elements include using target language (L2), avoiding translation, employing elicitation and guided discovery, and implementing concept check questions (CCQs). Effective lesson structures like Engage-Study-Activate (ESA) are explained, along with error correction techniques and providing positive reinforcement. The importance of learner objectives and varied teaching materials is also stressed.
