"An Investigation into the Practice of English Language Teaching" is a comprehensive study that examines the practice of English teaching in independent classes. The investigation aims to capture the attitudes of teachers and parents, assess the competence of teachers, and analyze the impact of professional development measures on English instruction. The results show that many teachers are not interested in teaching English in independent classes and often rely on textbooks without integrating appropriate teaching materials or innovative methods such as music and dance. The study highlights the need for targeted professional development offerings to support teachers in their subject expertise and improve the quality of instruction. Additionally, it addresses the negative attitude of parents towards the independent teaching format, indicating a further need for action.
