<p>This study examines how deep learning supports English language instruction that is explicitly culture-informed and situation-based. The teaching objectives are clear: to improve learners’ abilities in (a) cultural knowledge about Anglophone societies relevant to English use, (b) context-sensitive language reasoning, and (c) interactive classroom participation. We analyze the applicability of representative models to three tasks—cultural text learning, context recognition, and intelligent classroom interaction—using text classification, semantic similarity, and question-answering pipelines. Results show that Transformer and BiLSTM yield high accuracy in cultural text understanding and enhance learners’ cognitive grasp of language–culture links. Deep learning also improves context reasoning in complex scenarios and, through intelligent interaction, increases participation and feedback quality. We discuss constraints (data quality, computation, personalization) and outline future work on knowledge graphs, multimodal learning, and adaptive mechanisms to raise the instructional value of deep learning in language education.</p>
