As an English teacher, I have designed and delivered courses tailored to different age groups, focusing on their specific learning needs and cognitive development. For primary school students (0-3 years), my approach centered on early language exposure through interactive storytelling, songs, and playful activities that fostered basic vocabulary acquisition and listening skills. For secondary school students (9-14 years), I structured lessons around grammar, reading comprehension, writing exercises, and conversational practice, ensuring a balanced development of all language skills while encouraging critical thinking and creativity. In adult education (18-22 years), I emphasized advanced language proficiency, academic writing, professional communication, and critical analysis, equipping students with the linguistic tools necessary for higher education and career opportunities. My methodology integrated student-centered learning, fostering engagement and confidence in using English across various contexts.
